1126 * exp_ch6.adb (Expand_Call): Remove ugly special-case code that resets
1127 Orig_Prev to Prev in the case where the actual is N_Function_Call or

3322 (Build_Discriminated_Subtype): Do not inherit representation clauses
3323 from parent type if subtype already carries them, because they are
3324 inherited earlier during derivation and already include those that may
3325 come from a partial view.

3365 (Collect_Interps): When only one interpretation has been found, set N's
3366 Entity and Etype to that interpretation, otherwise Entity and Etype may
3367 still refer to an interpretation that was ignored by Add_One_Interp,
3368 in which case would end up with being marked as not overloaded but with

7385 reference before the actual is resolved and expanded, to prevent
7386 spurious warnings on formals of enclosing protected operations.
7387 (Analyze_Overloaded_Selected_Component): If type of prefix if
7388 class-wide, use visible components of base type.

7494 clauses for inherited components of a type extension.
7495 (Rep_Item_Too_Late): Do not attempt to link pragma into rep chain for
7496 an overloadable item if it is a pragma that can apply to multiple
7497 overloadable entities (e.g. Inline) because a pragma cannot be on
7498 more than one chain at a time.

7628 subprogram body that acts as its own spec may not have a non-private
7629 WITH clause on a private sibling.
7630 (Build_Unit_Name): If the parent unit in the name in a with_clause on a
7631 child unit is a renaming, create an implicit with_clause on that
7632 parent, and not on the unit it renames, to prevent visibility errors

7736 (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
7737 Timed_Entry_Call): Analyze the triggering statement as the first step of
7738 the processing. If this is a dispatching select, postpone the analysis
7739 of all select statements until the Expander transforms the select. This

7741 replicated some of the select statements. In case the Expander is
7742 disabled, perform regular analysis.
7743 (Check_Triggering_Statement): New routine.
7744 (Analyze_Requeue): Exclude any interpretations that are not entries when
7745 checking overloaded names in a requeue. Also test type conformance for

7754 for the defaulted actual.
7756 2007-12-13 Geert Bosch <bosch@adacore.com>
7758 * sem_eval.adb (Eval_Real_Literal): N_Constant_Declaration is a static

8341 multiple inherited interfaces info. This information cannot be stored
8342 in Xref_Entity_Record, which only supports a single instance of Tref_*,

8361 * exp_disp.adb (Expand_Interface_Actuals): Code cleanup. Remove code
8362 that handles use of 'Access and 'Unchecked_Access applied to

8364 centralized in Expand_N_Attribute_Reference.

8370 (Freeze_Array_Type): For a packed array type, generate an initialization
8371 procedure if the type is public, to handle properly a client that
8372 specifies Normalize_Scalars.
8374 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
8376 * exp_ch9.adb (Actual_Index_Expression): When the expansion occurs

8408 vx_stack_info.{c,o} that contains the routine __gnat_get_stack_info
8409 used by VxWorks targets to have access to task-specific data and be
8410 able to extract the stack boundaries for stack checking.
8411 Use system-vms-ia64.ads on ivms.
8413 * Make-lang.in: Update dependencies.
8415 * sysdep.c (__gnat_get_stack_info): Move to a standalone file
8418 2007-10-15 Vincent Celier <celier@adacore.com>

8452 2007-10-15 Gary Dismukes <dismukes@adacore.com>
8454 * sem_aggr.adb (Resolve_Record_Aggregate): In the case of a box
8455 association for an access component, add an association with null as
8456 the expression. Remove testing for array subtypes and the setting in
8457 that case of Ctyp to the array component type, which prevented proper
8458 inclusion of an association for null-initialized arrays. Collapse
8459 condition that tests for array subtypes into just a test of
8460 Is_Partially_Initialized_Type (which already covers arrays anyway).
8462 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
8464 * sem_ch12.adb: Minor code reformatting.
8465 (Check_Generic_Child_Unit): Iterate over the homonym chain in order to

8472 flag of derived concurrent types, taking into account the flag setting
8473 on the parent subtype and any new set of discriminants.
8475 2007-10-15 Hristian Kirtchev <kirtchev@adacore.com>
8477 * sem_ch4.adb: Minor code and comment reformatting.
8478 (Analyze_Allocator): When the designated type of an unconstrained
8479 allocator is a record with unknown discriminants or an array with
8480 unknown range bounds, emit a detailed error message depending on the
8481 compilation mode and whether the designated type is limited.
8483 2007-10-15 Tristan Gingold <gingold@adacore.com>
8485 * system-vms-ia64.ads: New file.

8556 to generate g-soccon-vms.ads.
8558 * atree.adb: Add ??? comment

8604 2007-09-27 Eric Botcazou <ebotcazou@adacore.com>
8606 Mapped location support
8607 * back_end.adb (Call_Back_End): Pass information about source
8608 files instead of units to gigi.
8609 * gigi.h (struct File_Info_Type): New.
8610 (gigi): Rename and change type of number_units parameter, change
8611 type of file_info_ptr parameter.
8612 * trans.c (number_files): New global variable.
8613 (gigi): Rename and change type of number_units parameter, change
8614 type of file_info_ptr parameter.
8615 If mapped location support is enabled, create the isomorphic mapping
8616 between source files and line maps.
8617 (Sloc_to_locus): If mapped location support is enabled, translate
8618 source location into mapped location.
8619 (annotate_with_node): Rename into set_expr_location_from_node.

8645 * a-calend-vms.adb, a-calend.adb:
8646 Add a section on leap seconds control along with two entities used to
8647 enable and disable leap seconds support. The array Leap_Second_Times is
8648 now constant and contains hard time values pre-generated. Remove
8649 all elaboration code used to populate the table of leap seconds.
8652 Add entity Leap_Seconds_Support to the list of global run-time variables
8653 along with a comment on its usage and values.
8654 (Gen_Adainit_Ada): Add code to generate the declaration and import of
8655 Integer variable Leap_Seconds_Support. Set its value to zero (disabled)
8656 or one (enabled) depending on the presence of binder switch "-y".
8657 (Gen_Adainit_C): Add code to generate the declaration of external int
8658 __gl_leap_seconds_support. Set is value to zero (disabled) or one

8669 s-taprop-posix.adb (Stop_Task): New function, dummy implementation.
8671 * s-taprop.ads, s-taprop-vxworks.adb (Stop_Task): New function.
8673 * s-tasdeb.adb (Stop_All_Tasks): New function, implementing a run-time
8674 function which can be called by the debugger to interrupt the tasks of
8675 an Ada application asynchronously, as needed on VxWorks.
8676 (Stop_All_Tasks_Handler): Renamed from Stop_All_Tasks.
8678 * s-tasdeb.ads (Stop_All_Tasks_Handler): New function declaration,
8679 renamed from Stop_All_Tasks. Update comments.

8695 * gnatvsn.ads (PCS_Version_Number, ASIS_Version_Number): Removed.
8697 * exp_dist.ads (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
8700 * opt.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
8702 * rtsfind.adb (PCS_Version_Number): Move from Gnatvsn to Exp_Dist,
8705 * sem_dist.ads: Minor comment fix
8707 * tree_io.ads: Move ASIS_Version_Number from Gnatvsn into Tree_IO.
8709 2007-09-26 Javier Miranda <miranda@adacore.com>
8710 Eric Botcazou <ebotcazou@adacore.com>
8713 (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
8714 indirection added to the HT_Link component of the TSD. This is required
8715 to statically allocate the TSD.
8718 Minor reordering of the declarations in the private part. Required to
8719 add a level of indirection to the contents of the TSD component HT_Link.
8720 This is required to statically allocate the TSD.
8722 * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
8723 Is_Statically_Allocated set from constant objects.
8724 Do not make exported constants created by the compiler volatile.
8725 (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
8728 * trans.c (Identifier_to_gnu): For constants, unshare initializers
8729 before returning them.
8731 * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
8732 public part of the package.
8733 (Make_DT): Move HT_Link component out of the TSD record. For this
8734 purpose Make_DT now declares a separate object that stores the
8735 HT_Link value, and initializes the TSD component with the address
8736 of this new object. The addition of this level of indirection is
8737 required to statically allocate the TSD because the TSD cannot
8738 have variable components.
8739 (Expand_Interface_Conversion): Improve the expanded code.
8740 (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
8742 * sem_disp.adb (Check_Dispatching_Operation): In case of a body
8743 declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
8744 if we are building static dispatch tables then we must not generate
8745 extra code to register the primitive because the dispatch table will
8746 be built at the end of the library package; otherwise we notify that
8747 we cannot build the static dispatch table.
8749 2007-09-26 Robert Dewar <dewar@adacore.com>
8751 * checks.adb, gnat1drv.adb, sem_util.ads: Improve warnings for address

8766 for thunks associated with interface types.
8768 * einfo.ads: Improve documentatation of Is_Internal
8769 (Is_Thunk): New attribute applicable to subprograms. True for thunks
8770 associated with interface types.
8771 Extensive comment fixes regarding flags that appear in all entities. The
8772 documentation is now consistent for all such flags (there were a number
8773 of errors in the documentation in this regard).
8775 * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
8777 * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
8778 of these procedures are passed a function call that already has
8779 build-in-place actuals (testing new flag
8780 Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
8781 the case where processing continues.
8782 (Expand_Call): If the call is generated from a thunk body then we
8783 propagate the extra actuals associated with the accessibility
8784 level of the access type actuals.
8786 * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
8787 of each extra formal of a protected operation to reference the
8788 corresponding extra formal of the subprogram denoted by the
8789 operation's Protected_Body_Subprogram.
8791 * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
8792 N_Function_Call nodes.
8794 2007-09-26 Robert Dewar <dewar@adacore.com>
8796 * exp_ch5.adb: Activate memmove type processing if debug flag d.s is set
8798 * debug.adb: Add d.s flag.
8800 2007-09-26 Gary Dismukes <dismukes@adacore.com>
8802 * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the
8803 debug variable so that it won't be initialized when pragma
8804 Initialize_Scalars is in effect.
8806 2007-09-26 Gary Dismukes <dismukes@adacore.com>
8808 * freeze.adb (Freeze_Entity): Remove check for preelaborable
8809 initialization of a full view. This is moved to
8810 Analyze_Package_Specification.
8812 * sem_ch7.adb (Analyze_Package_Specification): Add check for
8813 preelaborable initialization of a full view in entity loop.
8814 (Uninstall_Declarations): If entity is a use-visible compilation unit,
8815 its child units are use-visible only if they are visible child units.
8817 * sem_util.adb (Is_Preelaborable_Expression): New function to determine
8818 whether an expression can be used within a type declaration that
8819 requires preelaborable init.
8820 (Check_Components): Replace inline code that does partial checking for
8821 preelaborable default expressions with call to
8822 Is_Preelaborable_Expression.
8823 (Has_Preelaborable_Initialization): In the case of a generic actual
8824 subtype, (that is, Is_Generic_Actual is True), return the result of
8825 applying Has_Preelaborable_Initialization to the generic actual's base
8828 2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
8830 * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
8831 call to Jan_1_Day _Of_Week to optimize its performance.
8832 (Is_Leap): Move the routine to the scope of Week_In_Year.
8833 (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
8834 weekday on which January 1 falls of Year - 1 and Year + 1. This function
8835 avoids calling Time_Of and Split, thus making it more efficent.
8836 (Week_In_Year): Reimplemented in oder to follow ISO 8601.
8838 * g-calend.ads (Week_In_Year): Change comment to reflect new
8841 2007-09-26 Emmanuel Briot <briot@adacore.com>
8843 * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
8844 Command_Line): New types
8845 (Define_Alias, Define_Prefix, Free): New subprograms. These provide
8846 support for defining how switches can be grouped on a command line (as
8847 is the case for -gnatw... for GNAT), and how simple switches can be
8848 used as aliases for more complex switches (-gnatwa is same as
8850 (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
8851 (Start, Current_*): New subprograms
8852 Added support for parsing an array of strings in addition to the real
8854 (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
8855 be moved from the body to the private part of the spec.
8856 (*): All subprograms now have an extra parameter with default value to
8857 specify which parser should be used. For backward compatibility, it
8858 defaults to parsing the command line of the application. They were also
8859 modified to properly handle cases where each of the argument does not
8860 start at index 1 (which is always true for Ada.Command_Line, but not
8861 when processing any Argument_List).
8862 (Free): New subprogram
8863 (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
8864 Argument): New subprograms
8865 (Switch_Parameter_Type): New enum, which clarifies the code. The extra
8866 special characters like ':', '=',... are now handled in a single place,
8867 which makes the code more extensible eventually.
8868 (Getopt, Full_Switch): When the switch was returned as part of the
8869 special character '*', make sure it is prepended by the switch character
8870 ('-' in general), so that the application knows whether "foo" or "-foo"
8871 was specified on the command line.
8873 2007-09-26 Florian Villoing <villoing@adacore.com>
8875 * g-dirope.adb (Remove_Dir): In case we are removing directories
8876 recursively, make sure that if an exception is raised during the
8877 processing, the current working directory is reset to its initial
8878 value before propagating the exception.
8880 2007-09-26 Vincent Celier <celier@adacore.com>
8882 * gnatbind.adb: If there are several ALI files specified and there is
8883 a main program to bind, the first ALI is expected to contain the main
8884 subprogram and the names of the binder generated files will be derived
8885 from the first ALI file name.
8886 (Gnatbind): Fix insertion character in invocation of Error_Msg
8888 2007-09-26 Vincent Celier <celier@adacore.com>
8890 * gnatcmd.adb (Check_Files): Do not include sources that have been

9278 variable, insert init proc call only after the shared variable
9279 procedures have been processed, because the IP call needs to undergo

9291 given a box association, the type of the component is discriminated,
9292 and the value of the discriminant is the discriminant of the enclosing
9293 type, retrieve its value from the aggregate itself, where it must have
9296 * sem_ch4.adb (Analyze_One_Call): Further refinement to previous fix,
9297 to remove other spurious ambiguities on arithmetic operations involving
9298 literals and addresses, on systems where Address is a visible integer
9299 type, when the operator is called in functional notation.
9300 (Try_Primitive_Operation): Within an instance, a call in prefixed form

9426 (Write_Entity_Flags): Write the status of flag Is_Raised.
9427 (Is_Descendent_Of_Address): New entity flag, to simplify handling of

9449 * exp_ch8.adb (Expand_N_Package_Renaming_Declaration): In the case of a
9450 library-level package renaming, pass the declaration associated with

9486 * sem_eval.adb (Eval_Concatenation): If the left operand is the empty
9487 string, and the right operand is a string literal (the case of "" &

9491 * stringt.adb (Store_String_Chars): Optimize by growing the
9492 String_Chars table all at once, rather than appending characters one by
9494 (Write_String_Table_Entry): If the string to be printed is very long,
9495 just print the first few characters, followed by the length. Otherwise,
9496 doing "pn(n)" in the debugger can take an extremely long time.
9498 * sem_prag.adb (Process_Interface_Name): Replace loop doing
9499 Store_String_Char with Store_String_Chars.

9518 * sem_ch3.adb: The predicate Is_Descendent_Of_Address is now an entity
9519 flag, for effiency. It is called when analyzing arithmetic operators
9520 and also for actuals in calls that are universal_integers. The flag is
9521 set for the predefined type address, and for any type or subtype
9524 * sem_ch4.adb (Analyze_One_Call): Reject an actual that is a
9525 Universal_Integer, when the formal is a descendent of address and the
9526 call appears in user code.

9593 * cstand.adb (Create_Standard): Create an entity for a zero-sized type
9594 associated with Standard_Debug_Renaming_Type, to be used as the type of
9595 the special variables whose names provide debugger encodings for
9596 renaming declarations.
9598 * einfo.ads, einfo.adb (Debug_Renaming_Link): Change to return Node25.

9606 (Debug_Renaming_Declaration): Replace creation of an enumeration type
9607 and literal with creation of a variable of type
9608 Standard_Debug_Renaming_Type whose name encodes both the renamed object
9609 and the entity of the renaming declaration.
9610 (Qualify_Entity_Name): Add the delayed qualification of the entity name
9611 part of the name of a variable that has a Debug_Renaming_Link.

9621 * exp_aggr.adb (Build_Record_Aggr_Code): Extend the test for an
9622 ancestor part given by an aggregate to test for an unchecked conversion,
9623 since this can occur in some cases when the ancestor part is a function
9624 call, and we don't want to fall into the recursive call to this
9625 procedure in that case.
9627 * exp_ch3.adb (Stream_Operation_OK): Revise tests for availability of
9628 stream attributes on limited types to account for user-specified
9629 attributes as well as whether Input (resp. Output) becomes available
9630 due to Read (resp. Write) being available for the type. Change Boolean
9631 variable to the more accurate name
9632 Has_Predefined_Or_Specified_Stream_Attribute. Change convoluted
9633 double-"not" predicate at beginning of return statement to more
9634 understandable form.
9636 * exp_ch5.adb (Expand_N_Extended_Return_Statement): If the extended
9637 return has an associated N_Handled_Sequence_Of_Statements, then wrap it
9638 in a block statement and use that as the first statement of the
9639 expanded return rather than incorrectly using the handled sequence as
9640 the first statement.
9642 * exp_ch6.adb (Expand_N_Subprogram_Declaration): If this is a protected
9643 operation, generate an explicit freeze node for it rather than
9644 generating extra formals, to ensure that gigi has the proper order of
9645 elaboration for anonymous subtypes in the signature of the subprograms.
9646 (Build_In_Place_Formal): Move assertion to beginning of loop.
9647 (Is_Build_In_Place_Function_Call): Allow for an unchecked conversion
9648 applied to a function call (occurs for some cases of 'Input).

9650 applied to a function call (occurs for some cases of 'Input).
9652 * exp_strm.adb (Build_Record_Or_Elementary_Input_Function): For Ada
9653 2005, generate an extended return statement enclosing the result object
9656 * freeze.adb (Freeze_Record_Type): Extend the current management of
9657 components that are access type with an allocator as default value: add
9658 missing support to the use of qualified expressions of the
9659 allocator (which also cause freezing of the designated type!)
9660 (Freeze_Entity): Call Freeze_Subprogram in the case of a predefined
9661 dispatching operation, since extra formals may be needed by calls to
9662 build-in-place functions (such as stream 'Input).
9664 * sem_ch6.adb (Create_Extra_Formals): Skip creation of the extra
9665 formals for 'Constrained and accessibility level in the case of a
9666 predefined dispatching operation.
9668 * exp_util.adb (Insert_Actions): A protected body is a valid insertion
9669 point, no need to find the parent node.
9671 2007-08-16 Javier Miranda <miranda@adacore.com>
9673 * exp_attr.adb (Attribute_Priority): Add missing support for entries
9676 2007-08-16 Javier Miranda <miranda@adacore.com>
9678 * exp_ch9.adb (Build_Protected_Entry): Undo previous change because it
9679 is not really required and can introduce regression with the debugger.
9680 The original problem is fixed with the patch written for checks.adb.
9682 2007-08-16 Thomas Quinot <quinot@adacore.com>
9684 * g-dyntab.adb, g-table.adb, table.adb: (Set_Item): Suppress

9694 * makeutl.adb, makeutl.ads (Test_If_Relative_Path): New Boolean
9695 parameter Including_Non_Switch, defaulted to True. When
9696 Including_Non_Switch is False, options that are not switches and
9697 appear as relative path are not converted to absolute paths.

9721 * sem_ch12.adb (Copy_Generic_Node): A reference to a child unit of the
9722 generic for an enclosing instance is a global reference, even though
9723 its scope is the enclosing instance.

9749 * sem_res.adb (Comes_From_Predefined_Lib_Unit): New.
9750 (Resolve): Alphabetize local variables. Add new variable From_Lib. When
9751 the statement which is being resolved comes from a predefined library
9752 unit, all non-predefined library interpretations are skipped.
9753 (Resolve_Op_Concat): If string concatenation was folded in the parser,
9754 but the "&" is user defined, give an error, because the folding would
9757 * sinfo.ads, sinfo.adb (Is_Folded_In_Parser): New flag to indicate that
9758 the parser has folded a long sequence of concatenations of string
9761 * trans.c (Handled_Sequence_Of_Statements_to_gnu): Mark "JMPBUF_SAVE"
9762 and "JMP_BUF" variables as artificial.

9811 * inline.adb, types.ads, inline.ads, frontend.adb, alloc.ads:
9812 Suppress unmodified in-out parameter warning in some cases
9813 This patch is a also fairly significant change to the way suppressible
9816 * checks.ads, checks.adb (Install_Null_Excluding_Check): No check
9817 needed for access to concurrent record types generated by the expander.
9818 (Generate_Range_Check): When generating a temporary to capture the
9819 value of a conversion that requires a range check, set the type of the
9820 temporary before rewriting the node, so that the type is always
9821 properly placed for back-end use.
9822 (Apply_Float_Conversion_Check): Handle case where the conversion is
9824 (Get_Discriminal): Code reformatting. Climb the scope stack looking
9825 for a protected type in order to examine its discriminants.

9832 * a-stzsup.adb, nlists.adb, lib-util.adb, treepr.adb,
9833 a-stwisu.adb, a-strsup.adb: Fix warnings for range
9834 tests optimized out.
9836 * exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
9837 (Get_Allocator_Final_List): For the case of an anonymous access type
9838 that has a specified Associated_Final_Chain, do not go up to the
9840 (Expand_N_Type_Conversion): Test for the case of renamings of access
9841 parameters when deciding whether to apply a run-time accessibility
9843 (Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
9844 aggregate code before allocator, and ahead of declaration for
9845 temporary, to prevent access before elaboration when the allocator is
9846 an actual for an access parameter.
9847 (Expand_N_Type_Conversion): On an access type conversion involving an
9848 access parameter, do not apply an accessibility check when the
9849 operand's original node was an attribute other than 'Access. We now
9850 create access conversions for the expansion of 'Unchecked_Access and
9851 'Unrestricted_Access in certain cases and clearly accessibility should
9852 not be checked for those.
9854 * exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
9855 includes a type conversion of a packed component that has been expanded,
9856 recover the original expression for the object, and use this expression
9857 in the post-call assignment statement, so that the assignment is made
9858 to the object and not to a back-end temporary.
9859 (Freeze_Subprogram): In case of primitives of tagged types not defined
9860 at the library level force generation of code to register the primitive
9861 in the dispatch table. In addition some code reorganization has been
9862 done to leave the implementation clear.
9863 (Expand_Call): When expanding an inherited implicit conversion,
9864 preserve the type of the inherited function after the intrinsic
9865 operation has been expanded.
9867 * exp_ch2.ads, exp_ch2.adb
9868 (Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
9869 of an entry formal appearing in an assignment statement does not assign
9871 (Expand_Current_Value): Instead of calling a routine to determine
9872 whether the prefix of an attribute reference should be optimized or
9873 not, prevent the optimization of such prefixes all together.
9875 * lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
9876 component whose prefix is known to be of an access type is an implicit
9877 dereference and does not assign to the prefix.
9879 2007-08-14 Ed Schonberg <schonberg@adacore.com>
9880 Robert Dewar <dewar@adacore.com>
9882 * atree.ads, atree.adb (New_Copy_Tree): If hash table is being used and
9883 itype is visited, make an entry into table to link associated node and
9885 Add comments and correct harmless error in Build_NCT_Hash_Tables
9886 (Array_Aggr_Subtype): Associate each itype created for an index type to
9887 the corresponding range construct, and not to the aggregate itself. to
9888 maintain a one-to-one correspondence between itype and its associated
9889 node, to prevent errors when complex expression is copied.
9890 Fix mishandling of multiple levels of parens
9892 * sem_aggr.adb: Create a limited view of an incomplete type, to make
9893 treatment of limited views uniform for all visible declarations in a
9894 limited_withed package.
9895 (New_Copy_Tree): If hash table is being used and itype is visited,
9896 make an entry into table to link associated node and new itype.
9897 (Resolve_Record_Aggregate): Do not add an others box association for a
9898 discriminated record component that has only discriminants, when there
9899 is a box association for the component itself.
9901 * par-ch4.adb: Fix mishandling of multiple levels of parens
9903 2007-08-14 Robert Dewar <dewar@adacore.com>
9905 * comperr.adb: Fix problem with suppressing warning messages from gigi

9908 errout.adb (Write_Eol): Remove trailing spaces before writing the line
9909 (Write_Eol_Keep_Blanks): New procedure to write a line, including
9910 possible trailing spaces.
9911 (Output_Source_Line): Call Write_Eol_Keep_Blanks to output a source line

9936 Javier Miranda <miranda@adacore.com>
9937 Gary Dismukes <dismukes@adacore.com>
9939 * einfo.ads, einfo.adb: Create a limited view of an incomplete type,
9940 to make treatment of limited views uniform for all visible declarations
9941 in a limited_withed package.
9942 Improve warnings for in out parameters
9943 (Set_Related_Interaface/Related_Interface): Allow the use of this
9944 attribute with constants.
9945 (Write_Field26_Name): Handle attribute Related_Interface in constants.
9946 Warn on duplicate pragma Preelaborable_Initialialization
9948 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
9949 generation of a freezing node to ensure proper management of null
9950 excluding access types in the backend.
9951 (Create_Extra_Formals): Test base type of the formal when checking for
9952 the need to add an extra accessibility-level formal. Pass the entity E
9953 on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
9954 originally being done in a couple of cases), to ensure that the
9955 Extra_Formals list gets set on the entity E when the first entity is
9957 (Conforming_Types): Add missing calls to Base_Type to the code that
9958 handles anonymous access types. This is required to handle the
9959 general case because Process_Formals builds internal subtype entities
9960 to handle null-excluding access types.
9961 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
9962 functions that need it, even when not marked Requires_Overriding.
9963 Improve warnings for in out parameters
9964 (Analyze_Function_Return): Warn for disallowed null return
9965 Warn on return from procedure with unset out parameter
9966 Ensure consistent use of # in error messages
9967 (Check_Overriding_Indicator): Add in parameter Is_Primitive.
9968 (Analyze_Function_Return): Move call to Apply_Constraint_Check before
9969 the implicit conversion of the expression done for anonymous access
9970 types. This is required to generate the code of the null excluding
9971 check (if required).
9973 * sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
9974 A formal parameter is never publicly referenceable outside of its body.
9975 (Check_References): For an unreferenced formal parameter in an accept
9976 statement, use the same warning circuitry as for subprogram formal
9978 (Warn_On_Unreferenced_Entity): New subprogram, taken from
9979 Output_Unreferenced_Messages, containing the part of that routine that
9980 is now reused for entry formals as described above.
9981 (Goto_Spec_Entity): New function
9982 (Check_References): Do not give IN OUT warning for dispatching operation
9983 Improve warnings for in out parameters
9984 (Test_Ref): Check that the entity is not undefinite before calling
9985 Scope_Within, in order to avoid infinite loops.
9986 Warn on return from procedure with unset out parameter
9987 Improved warnings for unused variables

9990 Javier Miranda <miranda@adacore.com>
9991 Gary Dismukes <dismukes@adacore.com>
9993 * exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
9994 (Expand_N_Attribute_Reference): Further unify the handling of the
9995 three forms of access attributes, using common code now for all three
9996 cases. Add a test for the case of applying an access attribute to
9997 an explicit dereference when the context is an access-to-interface
9998 type. In that case we need to apply the conversion to the prefix
9999 of the explicit dereference rather than the prefix of the attribute.
10000 (Attribute_Version, UET_Address): Set entity as internal to ensure
10001 proper dg output of implicit importation.
10002 (Expand_Access_To_Type): Removed.
10003 (Expand_N_Attribute_Reference): Merge the code from the three cases
10004 of access attributes, since the processing is largely identical for
10005 these cases. The substantive fix here is to process the case of a
10006 type name prefix (current instance case) before handling the case
10007 of interface prefixes.

10012 Robert Dewar <dewar@adacore.com>
10014 * exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
10015 (Freeze_Array_Type, Freeze_Record_Type): For the case of a component
10016 type that is an anonymous access to controlled object, establish
10017 an associated finalization chain to avoid corrupting the global
10018 finalization list when a dynamically allocated object designated
10019 by such a component is deallocated.
10020 (Make_Controlling_Function_Wrappers): Create wrappers for constructor
10021 functions that need it, even when not marked Requires_Overriding.
10022 (Initialize_Tag): Replace call to has_discriminants by call to
10023 Is_Variable_Size_Record in the circuitry that handles the
10024 initialization of secondary tags.
10025 (Is_Variable_Size_Record): New implementation.
10026 (Expand_N_Object_Declaration): Suppress call to init proc if there is a
10027 Suppress_Initialization pragma for a derived type.
10028 (Is_Variable_Size_Record): New subprogram.
10029 (Build_Offset_To_Top_Functions): New implementation that simplifies the
10030 initial version of this routine and also fixes problems causing
10031 incomplete initialization of the table of interfaces.
10032 (Build_Init_Procedure): Improve the generation of code to initialize the
10033 the tag components of secondary dispatch tables.
10034 (Init_Secondary_Tags): New implementation that simplifies the previous
10035 version of this routine.
10036 (Make_DT): Add parameter to indicate when type has been frozen by an
10037 object declaration, for diagnostic purposes.
10038 (Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
10039 diagnose attemps to freeze a subprogram when some untagged type of its
10040 profile is a private type whose full view has not been analyzed yet.
10041 (Freeze_Array_Type): Generate init proc for packed array if either
10042 Initialize or Normalize_Scalars is set.
10043 (Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
10044 constructing the new profile, copy the null_exclusion indicator for each
10045 parameter, to ensure full conformance of the new body with the spec.
10047 * sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
10048 Create wrappers for constructor functions that need it, even when not
10049 marked Requires_Overriding.
10050 (Covers): Handle properly designated types of anonymous access types,
10051 whose non-limited views are themselves incomplete types.
10052 (Add_Entry): Use an entity to store the abstract operation which hides
10054 (Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
10055 (Collect_Interps): Use Empty as an actual for Abstract_Op in the
10056 initialization aggregate.
10057 (Function_Interp_May_Be_Hidden): Rename to
10058 Function_Interp_Has_Abstract_Op.
10059 (Has_Compatible_Type): Remove machinery that skips interpretations if
10060 they are labeled as potentially hidden by an abstract operator.
10061 (Has_Hidden_Interp): Rename to Has_Abstract_Op.
10062 (Set_May_Be_Hidden): Rename to Set_Abstract_Op.
10063 (Write_Overloads): Output the abstract operator if present.
10064 (Add_Entry): Before inserting a new entry into the interpretation table
10065 for a node, determine whether the entry will be disabled by an abstract
10067 (Binary_Op_Interp_May_Be_Hidden): New routine.
10068 (Collect_Interps): Add value for flag May_Be_Hidden in initialization
10070 (Function_Interp_May_Be_Hidden): New routine.
10071 (Has_Compatible_Type): Do not consider interpretations hidden by
10072 abstract operators when trying to determine whether two types are
10074 (Has_Hidden_Interp): New routine.
10075 (Set_May_Be_Hidden_Interp): New routine.
10076 (Write_Overloads): Write the status of flag May_Be_Hidden.
10078 2007-08-14 Ed Schonberg <schonberg@adacore.com>
10079 Javier Miranda <miranda@adacore.com>
10081 * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
10082 types declared in the declarative part of a nested package body or in
10083 the proper body of a stub.
10084 (Set_All_DT_Position): Add missing check to avoid wrong assignation
10085 of the same dispatch table slot to renamed primitives.
10086 (Make_Select_Specific_Data_Table): Handle private types.
10087 (Tagged_Kind): Handle private types.
10088 (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
10089 output of implicit importation and exportation.
10090 (Expand_Interface_Thunk): Fix bug in the expansion assuming that the
10091 first formal of the thunk is always associated with the controlling
10092 type. In addition perform the following code cleanup: remove formal
10093 Thunk_Alias which is no longer required, cleanup evaluation of the
10094 the controlling type, and update the documentation.
10095 Replace occurrence of Default_Prim_Op_Count by
10096 Max_Predef_Prims. Addition of compile-time check to verify
10097 that the value of Max_Predef_Prims is correct.
10098 (Check_Premature_Freezing): Apply check in Ada95 mode as well.
10099 (Make_DT): Add parameter to indicate when type has been frozen by an
10100 object declaration, for diagnostic purposes.
10101 (Build_Static_Dispatch_Tables): New subprogram that takes care of the
10102 construction of statically allocated dispatch tables.
10103 (Make_DT): In case of library-level tagged types export the declaration
10104 of the primary tag. Remove generation of tags (now done by Make_Tags).
10105 Additional modifications to handle non-static generation of dispatch
10106 tables. Take care of building tables for asynchronous interface types
10107 (Make_Tags): New subprogram that generates the entities associated with
10108 the primary and secondary tags of Typ and fills the contents of Access_
10109 Disp_Table. In case of library-level tagged types imports the forward
10110 declaration of the primary tag that will be declared later by Make_DT.
10111 (Expand_Interface_Conversion): In case of access types to interfaces
10112 replace an itype declaration by an explicit type declaration to avoid
10113 problems associated with the scope of such itype in transient blocks.
10115 2007-08-14 Robert Dewar <dewar@adacore.com>
10116 Ed Schonberg <schonberg@adacore.com>
10117 Javier Miranda <miranda@adacore.com>
10119 * exp_util.ads, exp_util.adb:
10120 This patch replaces a number of occurrences of explicit tests for N_Null
10121 with calls to Known_Null. This improves tracking of null values, since
10122 Known_Null also catches null constants, and variables currently known to
10123 be null, so we get better tracking.
10124 (Ensure_Defined): create an itype reference only in the scope of the
10126 (Side_Effect_Free): A selected component of an access type that
10127 denotes a component with a rep clause must be treated as not
10128 side-effect free, because if it is part of a linked structure its
10129 value may be affected by a renaming.
10130 (Expand_Subtype_From_Expr): For limited objects initialized with build
10131 in place function calls, do nothing; otherwise we prematurely introduce
10132 an N_Reference node in the expression initializing the object, which
10133 breaks the circuitry that detects and adds the additional arguments to
10134 the called function. Bug found working in the new patch for statically
10135 allocated dispatch tables.
10136 (Is_Library_Level_Tagged_Type): New subprogram.
10137 (Remove_Side_Effects): If the expression of an elementary type is an
10138 operator treat as a function call.
10139 (Make_Literal_Range): If the index type of the array is not integer, use
10140 attributes properly to compute the constraint on the resulting aggregate
10143 * freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
10144 class-wide type whose base type is an incomplete private type, leave
10145 class-wide type unfrozen so that freeze nodes can be generated
10146 properly at a later point.
10147 (Freeze_Entity, array case): Handle case of pragma Pack and component
10148 size attributre clause for same array.
10150 2007-08-14 Vincent Celier <celier@adacore.com>

10202 Update Project Manager to new attribute names for ghprbuild
10203 Allow all valid declarations in configuration project files
10204 (Search_Directories): Detect subunits that are specified with an
10205 attribute Body in package Naming. Do not replace a source/unit in the
10206 same project when the order of the source dirs are known. Detect
10207 duplicate sources/units in the same project when the order of the
10208 source dirs are not known.
10209 (Check_Ada_Name): Allow all identifiers that are not reserved words
10211 Major update of the Project Manager and of the project aware tools,
10212 including gprmake, so that the same sources in the GNAT repository
10213 can be used by gprbuild.

10215 directory of non extending project to nil.
10216 Change type of path name variables to be Path_Name_Type
10217 (Locate_Directory): Make sure that on Windows '/' is converted to '\',

10227 insensitive flag for attributes with optional index.
10228 (Prj.Dect.Parse_Attribute_Declaration): For case insensitive associative
10229 array attribute, put the index in lower case.

10798 (Collect_Previous_Instances): new procedure within of
10799 Load_Parent_Of_Generic, to instantiate all bodies in the compilation

10803 takes progenitor types into account.
10804 (Validate_Derived_Type_Instance): Enforce the rule of 3.9.3(9) by
10805 traversing over the primitives of the formal and actual types to locate
10806 any abstract subprograms of the actual type that correspond to a
10807 nonabstract subprogram of the formal type's ancestor type(s), and issue
10808 an error if such is found.
10809 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation,

10824 an access_to_constant type.
10825 (Try_Primitive_Operation): If the type of the prefix is a formal tagged
10826 type, the candidate operations are found in the scope of declaration of
10827 the type, because the type has no primitive subprograms.
10828 (Analyze_Selected_Component): If prefix is class-wide, and root type is
10829 a private extension, only examine visible components before trying to
10830 analyze as a prefixed call.
10831 Change Entity_List to Type_To_Use, for better readability.

10845 purpose of enforcing E.2.2(8) only if it is not available at any place.
10846 Take into account the Ada2005 pragma Has_Preelaborable_Initialization
10847 when checking the legality of an extension aggregate in a preelaborable
10848 package. Treat the literal null as a valid default expression in a
10849 component declaration for a type with preelaborable initialization.
10850 A limited interface is a legal progenitor for the designated type of a
10851 remote access to class-wide type.

10882 (Resolve): When looping through all possible interpretations of a node,
10883 do not consider those that are hidden by abstract operators.
10884 (Resolve_Actuals): When verifying that an access to class-wide object
10885 is an actual for a controlling formal, ignore anonymous access to
10886 subprograms whose return type is an access to class_wide type.
10887 (Resolve_Slice): If the prefix of the slice is a selected component
10888 whose type depends on discriminants, build its actual subtype before
10889 applying range checks on the bounds of the slice.
10890 (Valid_Conversion): In an instance or inlined body, compare root types,
10891 to prevent anomalies between private and public views.

10913 elabration statements, register the package with the name server
10914 at the beginning, not at the end, of the elaboration statements so

12031 * checks.ads, checks.adb (Apply_Address_Clause_Check): Handle case in
12032 which the address-clause is applied to in-mode actuals (allowed by
12034 (Apply_Discriminant_Check): Do not generate a check if the type is
12035 constrained by a current instance.
12036 (Activate_Division_Check): New procedure
12037 (Activate_Overflow_Check): New procedure
12038 (Activate_Range_Check): New procedure
12039 Call these new Activate procedures instead of setting flags directly
12040 (Apply_Array_Size_Check): Removed, no longer needed.
12041 Code clean up: remove obsolete code related to GCC 2.
12042 (Get_E_Length): Protect against bomb in case scope is standard
12043 (Selected_Range_Checks): If the node to be checked is a conversion to
12044 an unconstrained array type, and the expression is a slice, use the
12045 bounds of the slice to construct the required constraint checks.
12046 Improve NOT NULL error messages
12047 (Apply_Constraint_Check): If the context is a null-excluding access
12048 type, diagnose properly the literal null.
12050 2007-06-06 Pascal Obry <obry@adacore.com>
12052 * clean.adb (Clean_Archive): Use untouched casing for the archive name
12053 and the corresponding .deps file.
12054 (Clean_Interface_Copy_Directory): Use untouched casing for the library
12055 src directory. Minor code-clean-up. Use untouched casing for files
12056 read into the library src dir.
12057 (Clean_Library_Directory): Idem.
12058 (Parse_Cmd_Line): Accept new switch -aP

12063 Eric Botcazou <ebotcazou@adacore.com>
12064 Arnaud Charlet <charlet@adacore.com>
12066 * einfo.ads, einfo.adb (Available_View): New synthesized attribute
12067 applicable to types that have the With_Type flag set. Returns the
12068 non-limited view of the type, if available, otherwise the type itself.
12069 For class-wide types, there is no direct link in the tree, so we have
12070 to retrieve the class-wide type of the non-limited view of the Etype.
12071 New attributes Static_Initialization and Static_Elaboration_Desired.
12072 Remove the pragma Thread_Body, and the associated flag
12073 Is_Thread_Body in entities, and all related code.
12074 (Suppress_Value_Tracking_On_Call): New flag
12075 E_Exception has Esize and Alignment fields
12076 (Universal_Aliasing): New function.
12077 (Set_Universal_Aliasing): New procedure.
12078 (Write_Entity_Flags): Deal with Universal_Aliasing flag.
12079 (Check_Nested_Access): New procedure.
12080 (Has_Up_Level_Access, Set_Has_Up_Level_Access): New procedures.
12081 (Find_Direct_Name, Note_Possible_Modification): Use Check_Nested_Access.
12082 (Related_Interface): New attribute. Present in dispatch table pointer
12083 components of records. Set to point to the entity of the corresponding
12085 (Is_By_Reference_Type): Recurse on the full view of an incomplete type.
12086 (Original_Access_Type): Remove, not needed.
12087 (Root_Type): Handle properly subtypes of class-wide-types.
12090 * sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
12091 class-wide types visible through limited-with clauses.
12092 (Try_Primitive_Operation): When examining all primitive operations of a
12093 tagged type, do not consider subprograms labeled as hidden unless they
12094 belong to a private generic type with a tagged parent.
12095 (Try_Object_Operation): Extensive rewriting, to handle properly various
12096 overloading cases, when several ancestors may have class-wide operations
12097 that are possible candidates, and when the overloaded functions return
12098 array types and have defaulted parameters so that the call may be
12099 interpreted as an indexing.
12100 (Analyze_Allocator): Remove Mark_Allocator and its invocation.
12101 (Process_Function_Call): use Next, rather than Next_Actual, to analyze
12102 successive actuals before analyzing the call itself.
12103 (Try_Primitive_Operation): A primitive operation is compatible with the
12104 prefix if the prefix has a synchronized type and the type of the formal
12105 is its corresponding record, as can be the case when the primitive
12106 operation is declared outside of the body of the type.
12107 (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
12108 perform homonym traversal, looking for class-wide operation matches
12109 (formerly done in statements of Try_Class_Wide_Operation). Matches on
12110 access parameters are now restricted to anonymous access types.
12111 (Mark_Allocator): An allocator with a discriminant association parent is
12113 (Try_One_Prefix_Interpretation): If the type of the object is
12114 incomplete, as can be happen when it is a limited view obtained through
12115 a limited_with_clause, the selected component is not part of a prefixed
12117 (Complete_Object_Operation): Diagnose properly an object that is not
12118 aliased when the corresponding controlling formal is an access
12120 (Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
12121 ambiguous calls in prefixed notation, where two primitives differ only
12122 in that the controlling argument of one is an access parameter.
12124 * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
12125 whether a function that returns an unconstrained type can be inlined.
12126 (Process_Formals): Diagnose properly the illegal use of an incomplete
12127 type in the profile of an access_to_subprogram declaration.
12128 (Check_Synchronized_Overriding): Nothing check for concurrent types, the
12129 operations are attached to the corresponding record.
12130 (Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
12131 When processing a primitive of a concurrent type which implements an
12132 interface change the type of all controlling formals to that of the
12133 corresponding record type.
12134 (Check_Synchronized_Overriding): Relax the conditional logic when trying
12135 to determine the tagged type to which a primitive belongs.
12136 (Check_Conventions): Capture condition to ignore a primitive operation
12137 (which is shared between the loop in Check_Conventions and the one in
12138 Check_Convention) in a new local function Skip_Check.
12139 (Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
12140 confusion with Check_Conventions' own Prim_Op local variable.
12141 (Create_Extra_Formals): Test for a tagged result type rather than a
12142 controlling result when determining whether to add a BIP_Alloc_Form
12143 formal and a BIP_Final_List formal to the function.
12144 (Check_Conformance); For parameters that are anonymous access types,
12145 subtype conformance requires that the not null and the constant
12146 indicators must match
12147 (Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
12148 to retrieve the appropriate type when processing a concurrent type
12149 declared within a generic. Minor comment reformatting. Change invocation
12150 of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
12152 (Analyze_Subprogram_Body): If the return type of a function is an
12153 anonymous access to the limited view of a class-wide type, and the
12154 non-limited view of the type is available, update the type of the
12155 function so that code can be generated.
12156 (Process_Formals): In case of access-subtype itype whose designated
12157 type is also an itype (situation that happens now with access to
12158 subprograms) we mark the access-type itype with the Has_Delayed_Freeze
12159 attribute to avoid backend problems.
12160 (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
12161 init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
12162 anonymous types' designated types are same before testing
12163 Subtypes_Statically_Match.
12164 (Create_Extra_Formals): Test for a named access parameter that is a
12165 controlling formal as an additional condition for adding an
12166 accessibility level formal. This can occur in the subp type created for
12167 dispatching calls in Expand_Dispatching_Call, and allows calling
12168 Create_Extra_Formals from that procedure rather than special-casing the
12169 extra formals there.
12170 (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
12171 when the function has a controlling result.
12172 (Check_Returns): Add much more knowledge of the optimization of local
12173 raise statements to gotos, to retain proper warnings in this case.
12174 (Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
12175 nodes when looking for last statement.
12177 * sem_type.ads, sem_type.adb (Specific_Type): Add support for
12178 class-wide types visible through limited with clauses.
12179 (Add_One_Interp): If the operands are anonymous access types, the
12180 predefined operator on universal_access is immediately visibles
12181 (Find_Unique_Type): Handle anonymous access to subprogram types just as
12182 other anonymous access types.
12183 (Disambiguate): Take into account CIL convention.
12184 (Interface_Present_In_Ancestor): Add support for class-wide interfaces.
12186 2007-06-06 Robert Dewar <dewar@adacore.com>

12191 Fix lower bound of tables.
12194 * nlists.adb: Ditto.
12195 (Prev_Node, Next_Node): Change index type to Int so that it properly
12196 covers the range First_Node_Id - 1 up.

12201 Hristian Kirtchev <kirtchev@adacore.com>
12203 * exp_aggr.ads, exp_aggr.adb:
12204 (Build_Record_Aggr_Code): Add missing initialization of secondary tags
12205 in extension aggregates.
12206 (Flatten): Other conditions being met, an aggregate is static if the
12207 low bound given by component associations is different from the low
12208 bound of the base index type.
12209 (Packed_Array_Aggregate_Handled): If the component type is itself a
12210 packed array or record, the front-end must expand into assignments.
12211 (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to
12212 Init_Pr, instead of Ancestor_Is_Expression.
12213 (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a
12214 coextension chain root, either generate a list controller or use the
12215 already existing one.
12216 (Static_Array_Aggregate): New procedure to construct a positional
12217 aggregate that can be handled by the backend, when all bounds and
12218 components are compile-time known constants.
12219 (Expand_Record_Aggregate): Force conversion of aggregates of tagged
12220 types covering interface types into assignments.
12221 (Replace_Type): move to Build_Record_Aggr_Code.
12222 (Expand_Record_Aggr_Code): if the target of the aggregate is an
12223 interface type, convert to the definite type of the aggregate itself,
12224 so that needed components are visible.
12225 (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
12226 components and the context is an extended return statement do not
12227 create a transient block for it, to prevent premature finalization
12228 before the return is executed.
12229 (Gen_Assign): Do not generate a call to deep adjust routine if the
12230 component type is itself an array of controlled (sub)-components
12231 initialized with an inner aggregate.
12232 (Component_Check): New name for Static_Check. This name is now more
12233 appropriate, and documentation is added which was missing.
12234 (Component_Check): Add test for bit aligned component value
12235 (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_
12236 Tagged_Comps, name is more appropriate given added function below.
12237 (Component_Not_OK_For_Backend): Check for bit aligned component ref.

12240 Javier Miranda <miranda@adacore.com>
12241 Robert Dewar <dewar@adacore.com>
12243 * exp_attr.adb (Expand_N_Attribute_Reference): Case Callable and
12244 Terminated: Add unchecked type conversion from System.Address to
12245 System.Tasking.Task_Id when calling the predefined primitive
12247 Disable new Ada 05 accessibility check for JVM.NET targets, which
12248 cannot be implemented in a practical way.
12249 (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
12250 the sources always references the tag of the actual object. Therefore,
12251 if 'Tag is applied in the sources to class-wide interface objects we
12252 generate code that displaces "this" to reference the base of the object.
12253 (Expand_N_Attribute_Reference, case Size): Return specified size if
12254 known to front end.
12255 (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
12256 has code that displaces the pointer of the object to manage interface
12257 types. However this code must not be executed when the prefix is a
12258 subprogram. This bug caused the wrong expansion of the internally
12259 generated assignment that fills the dispatch table when the primitive
12260 is a function returning a class-wide interface type.
12261 (Expand_N_Attribute_Reference:Attribute_Valid): Remove incorrect call to
12262 Set_Attribute_Name for Name_Unaligned_Valid.
12264 2007-06-06 Ed Schonberg <schonberg@adacore.com>
12265 Gary Dismukes <dismukes@adacore.com>
12267 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case 'Address):
12268 If the initialization is the equivalent aggregate of the initialization
12269 procedure of the type, do not remove it.
12270 (Expand_N_Attribute_Definition_Clause): Exclude access variables
12271 initialized to null from having their expression reset to empty and
12272 note this exception in the comment.

12276 Ed Schonberg <schonberg@adacore.com>
12277 Gary Dismukes <dismukes@adacore.com>
12279 * exp_ch2.adb: Remove "with" and "use" clauses for Namet and Snames.
12280 Add "with" and "use" clauses for Sem_Attr.
12281 (Expand_Current_Value): Do not replace occurences of attribute
12282 references where the prefix must be a simple name.
12284 * sem_attr.ads, sem_attr.adb: Remove "with" and "use" clauses for
12285 Namet. Add new arrays Attribute_Name_Modifies_Prefix and
12286 Attribute_Requires_Simple_Name_Prefix.
12287 (Name_Modifies_Prefix): Body of new function.
12288 (Requires_Simple_Name_Prefix): Body of new function.
12289 (Resolve_Attribute, case Access): Improve error message for case of
12290 mismatched conventions.
12291 (Analyze_Attribute, case 'Tag): The prefix the attribute cannot be of an
12293 (Analyze_Attribute, case 'Access): If the type of the prefix is a
12294 constrained subtype for a nominal unconstrained type, use its base type
12295 to check for conformance with the context.
12296 (Resolve_Attribute): Remove test of the access type being associated
12297 with a return statement from condition for performing accessibility
12298 checks on access attributes, since this case is now captured by
12299 Is_Local_Anonymous_Access.
12300 (Analyze_Access_Attribute): Set Address_Taken on entity
12301 (Analyze_Attribute, case Address): Set Address_Taken on entity
12302 (OK_Self_Reference): Traverse tree to locate enclosing aggregate when
12303 validating an access attribute whose prefix is a current instance.
12304 (Resolve_Attribute): In case of attributes 'Code_Address and 'Address
12305 applied to dispatching operations, if freezing is required then we set
12306 the attribute Has_Delayed_Freeze in the prefix's entity.
12307 (Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
12308 current scope if access of local subprogram taken
12309 (Analyze_Access_Attribute): Check legality of self-reference even if the
12310 expression comes from source, as when a single component association in
12311 an aggregate has a box association.
12312 (Resolve_Attribute, case 'Access): Do not apply accessibility checks to
12313 the prefix if it is a protected operation and the attribute is
12314 Unrestricted_Access.
12315 (Resolve_Attribute, case 'Access): Set the Etype of the attribute
12316 reference to the base type of the context, to force a constraint check
12317 when the context is an access subtype with an explicit constraint.
12318 (Analyze_Attribute, case 'Class): If the prefix is an interface and the
12319 node is rewritten as an interface conversion. leave unanalyzed after
12320 resolution, to ensure that type checking against the context will take

12324 Javier Miranda <miranda@adacore.com>
12325 Robert Dewar <dewar@adacore.com>
12327 * exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
12328 wrapper when the full view of the controlling type of an inherited
12329 function that dispatches on result implements interfaces.
12330 (Expand_N_Object_Declaration): In cases where the type of the
12331 declaration is anonymous access, create finalization list for it.
12332 (Expand_N_Object_Declaration): Generate a persistent_bss directive only
12333 if the object has no explicit initialization, to match description of
12334 functionality of pragam Persistent_BSS.
12335 (Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
12336 new function to build static aggregates, to replace initialization call
12337 when static initialization is desired.
12338 (Freeze_Type): Generate a list controller for an access type whenever
12339 its designated type has controlled anonymous access discriminants.
12340 (Build_Equivalent_Aggregate): New procedure to compute a static
12341 aggregate to be used as default initialization for composite types,
12342 instead of a generating a call to the initialization procedure for the
12344 (Build_Initialization_Call): When available, replace a call to the
12345 initialization procedure with a copy of the equivalent static aggregate
12347 (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
12348 declarations for objects of a class-wide interface type, rather than
12349 just identifiers, to prevent visibility problems.
12350 (Expand_N_Object_Declaration): When expanding the declaration for an
12351 object of a class-wide interface type, preserve the homonym chain of
12352 the original entity before exchanging it with that of the generated
12353 renaming declaration.
12354 (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
12355 active, because there is no way to handle the exception.
12356 (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
12357 to do a minimum decoration of the Access_Disp_Table list.
12358 (Expand_Record_Controller): Avoid the addition of the controller between
12359 the component containing the tag of a secondary dispatch table and its
12360 adjacent component that stores the offset to the base of the object.
12361 This latter component is only generated when the parent type has
12362 discriminants ---documented in Add_Interface_Tag_Components).
12363 (Apply_Array_Size_Check): Removed, no longer needed.
12364 (Expand_N_Full_Type_Declaration): If the type has anonymous access
12365 components, create a Master_Entity for it only if it contains tasks.
12366 (Build_Init_Procedure): Suppress the tag assignment compiling under
12368 (Freeze_Record_Type): Remove code associated with creation of dispatch
12370 (Init_Secondary_Tags): Update type of actuals when generating calls to
12371 Ada.Tags.Set_Offset_To_Top
12372 (Stream_Operation_OK): Disable use of streams compiling under no
12374 (Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
12375 if Has_Init_Expression set.
12376 (Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
12377 Register_Primitive, which provides the same functionality.
12378 (Requires_Init_Proc): Return false in case of interface types.
12379 (Add_Secondary_Tables): Use the new attribute Related_Interface to
12381 (Predefined_Primitive_Freeze): Do not assume that an internal entity
12382 is always associated with a predefined primitive because the internal
12383 entities associated with interface types are not predefined primitives.
12384 Therefore, the call to Is_Internal is replaced by a call to the
12385 function Is_Predefined_Dispatching_Operation.
12386 (Make_Eq_If): When generating the list of comparisons for the
12387 components of a given variant, omit the controller component that is
12388 present if the variant has controlled components.

12391 Hristian Kirtchev <kirtchev@adacore.com>
12392 Bob Duff <duff@adacore.com>
12394 * exp_ch4.adb (Complete_Coextension_Finalization): Add machinery to
12395 handle the creation of finalization lists and calls for nested
12396 coextensions when the root of the chains is part of a return statement.
12397 (Inside_A_Return_Statement): New function inside Complete_Coextension_
12399 (Expand_Record_Equality): Skip components that are interface types.
12400 (Displace_Allocator_Pointer): Add missing support for interface subtypes
12401 (Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
12402 with Rewrite_Coextension. Change the condition for detecting coextension
12404 (Is_Local_Access_Discriminant): Removed.
12405 (Rewrite_Coextension): New routine which rewrites a static coextension
12406 as a temporary and uses its unrestricted access in the construction of
12408 (Complete_Coextension_Finalization): New routine. Generate finalization
12409 attachment calls to all delayed coextensions.
12410 (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
12411 the allocator is not a coextension itself and has delayed coextensions.
12412 If the current allocator is controlled, but also a coextension, delay
12413 the generation of the finalization attachment call.
12414 Rename local variable "Node" to "Nod" in order to avoid confusion with
12416 (Expand_Allocator_Expression): Call Adjust for initialized allocators of
12417 limited types that are not inherently limited. Such an allocator is
12418 illegal, but is generated by the expander for a return statement, to
12419 copy the result onto the secondary stack. This is the only case where a
12420 limited object can be copied. Generate code to displace the pointer
12421 to the object if the qualified expression is a class-wide interface
12422 object. Such displacement was missing and hence the copy of the object
12424 (Apply_Accessibility_Check): Handle allocated objects initialized in
12426 (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
12427 and Expand_Allocator_Expression. Allocating class-wide interface objects
12428 this routine displaces the pointer to the allocated object to reference
12429 the component referencing the corresponding secondary dispatch table.
12430 Expand_Allocator_Expression): Add missing support to allocate class-wide
12431 interface objects initialized with a qualified expression.
12432 (Get_Allocator_Final_List): Test for an anonymous access type that is a
12433 function result type, and use the finalization list associated with the
12434 function scope in that case (such an anonymous type should not be
12435 treated like an access parameter's type).

12439 Javier Miranda <miranda@adacore.com>
12441 * exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
12442 controlled type, use Make_Handler_For_Ctrl_Operation to construct the
12443 required exception handler.
12444 (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
12445 properly the case of a function whose return type is a limited
12446 class-wide interface type. Modify the code of the accessibility
12447 check to handle class-wide interface objects. In this case we need to
12448 displace "this" to reference the primary dispatch table to get access
12449 to the TSD of the object (to evaluate its accessibility level).
12450 (Expand_N_Extended_Return_Statement): Test for a tagged result type
12451 rather than a controlling result as one of the conditions for
12452 generating tests of the implicit BIP_Alloc_Form formal. The
12453 initialization assignment is also handled according to whether the
12454 result is tagged instead of controlling.
12455 In the case where the init assignment is inserted in the "then" part of
12456 the allocation conditional, rewrite the target to be a dereference of
12457 the implicit BIP_Object_Access formal.
12458 If the returned value is unconstrained and created on the secondary
12459 stack, mark the enclosing block and function so that the secondary
12460 stack is not reclaimed on return.
12461 Treat returns from functions with controlling results similarly to
12462 returns from functions with unconstrained result subtypes.
12463 If the object returned is unconstrained, and an allocator must be
12464 created for it, analyze the allocator once the block for the extended
12465 return is installed, to ensure that finalizable components
12466 of the expression use the proper finalization list. Guard the call to
12467 Move_Final_List with a check that there is something to finalize.
12468 (Make_Tag_Ctrl_Assignment): Use "old" handling
12469 of controlled type assignment for virtual machines, since new code uses
12470 unsupported features (such as direct access to bytes in memory).
12472 2007-06-06 Gary Dismukes <dismukes@adacore.com>
12473 Ed Schonberg <schonberg@adacore.com>
12475 * exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
12476 accessibility actual, check for the case of an aliased object that has
12477 been rewritten as an Access attribute, and assign Prev to Prev_Orig so
12478 we fall into processing for the attribute rather than the name of the
12480 (Expand_Inline_Call): If an actual is a literal, and the corresponding
12481 formal has its address taken in the body, create a temporary to capture
12482 value. If the return type is a limited interface, do not treat the
12483 return value as Controlled.
12484 (Is_In_Place_Function): If the return type is a limited interface,
12485 treat as returning in place. The actual returned object may not always
12486 be limited, but the caller has to assume that it is returned in place.
12487 (Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
12488 context of an allocator, use the correct finalization chain (that is,
12489 the chain belonging to the access type, rather than the chain belonging
12490 to the current scope).
12491 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
12492 result type rather than a controlling result as a precondition for
12493 adding an allocation form actual to a build-in-place call.
12494 (Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
12495 (Freeze_Subprogram): Code cleanup. Remove all the code that register the
12496 primitive in the dispatch tables. This work is now done by Make_DT when
12497 the type is frozen.
12498 (Register_Predefined_DT_Entry): Removed.
12499 (Add_Return): If end label is not present, use sloc of last statement
12500 for generated return statement in procedure, for better gdb behavior
12502 (Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
12503 object address nodes to ensure proper processing by routines like
12505 (Expand_Call): Fix generation of validity check for parameter
12506 (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
12507 the allocation form parameter if the result subtype is constrained,
12508 except when the function has a controlling result.
12509 (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
12510 rather than Is_Controlled and Has_Controlled_Component, since we want to
12511 include class-wide result types in this treatment. Also test for a
12512 controlling result, since that also requires passing a finalization
12514 (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
12515 even when the result subtype is constrained, to handle calls involving
12516 controlling results.
12517 (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
12518 is now called even when the result subtype is constrained, to handle
12519 calls involving controlling results.
12520 (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
12521 on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure
12522 now performs the test).
12523 (Make_Build_In_Place_Call_In_Object_Declaration):
12524 Add_Alloc_Form_Actual_* is now called even when the result subtype is
12525 constrained, to handle calls involving controlling results.
12526 (Add_Return): Accomodate rewritten pattern from local raise to goto
12527 transformation, so that we still recognize an transfer statement
12528 and do the right thing here in that case.
12529 (Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
12530 and end of subprogram code.
12531 (Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
12532 support for primitives that are functions (without formals) with a
12533 controlling result.
12534 (Inherited_From_Formal): If the actual subtype has not generic parent
12535 type, it is not an actual for a formal derived type, and there is no
12536 operation to inherit from the formal.
12538 2007-06-06 Ed Schonberg <schonberg@adacore.com>
12539 Thomas Quinot <quinot@adacore.com>
12541 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
12542 inserted cleanup code appropriately for GDB use.
12543 (Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
12544 exception handler for Deep_Adjust or Deep_Finalize.
12545 (Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
12546 Raise_From_Controlled_Operation is available, use a call to that
12547 subprogram instead of a plain "raise Program_Error" node to raise
12548 Program_Error if an exception is propagated from an Adjust or Finalize
12550 (Insert_Actions_In_Scope_Around): If the statement to be wrapped
12551 appears in the optional statement list of a triggering alternative, the
12552 scope actions can be inserted directly there, and not in the list that
12553 includes the asynchronous select itself.
12555 2007-06-06 Ed Schonberg <schonberg@adacore.com>
12556 Robert Dewar <dewar@adacore.com>
12557 Hristian Kirtchev <kirtchev@adacore.com>
12559 * exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry): Set sloc of
12560 generated exception handler appropriately when debugging generated code.
12561 Deal properly with No_Exception_Propagation restriction mode.
12562 (Expand_N_Abort_Statement): Add an unchecked type conversion from
12563 System.Address to System.Tasking.Task_Id when processing the result of
12564 the predefined primitive _disp_get_task_id.
12565 (Expand_N_Asynchronous_Select): Clarify comment.
12566 (Expand_N_Protected_Type_Declaration): Minor code cleanup.
12567 (Find_Parameter_Type): New routine inside Type_Conformant_Parameters.
12568 (Type_Conformant_Parameters): New parameter Prim_Op_Typ. Code cleanup.
12569 (Add_Private_Declarations, Build_Protected_Body): Use proper slocs for
12570 privals and for generated call to Complete_Entry_Body, for better gdb
12572 (Copy_Result_Type): Utility to construct a parameter and result profile
12573 for protected functions whose return type is an anonymous access to
12575 (Build_Protected_Sub_Spec and Expand_Access_Protected_Subprogram_Type):
12577 (Build_Task_Activation_Call): Insert Activate_Tasks call at proper
12578 point when the local-raise-to-goto transformation has taken place.
12580 2007-06-06 Javier Miranda <miranda@adacore.com>
12581 Nicolas Setton <setton@adacore.com>
12583 * exp_dbug.adb (Get_Encoded_Name): Modified to continue providing its
12584 functionality when the backend is generating code.
12585 Otherwise any serious error
12586 reported by the backend calling the frontend routine Error_Msg
12587 changes the Compilation_Mode to Check_Semantics, disables the
12588 functionality of this routine and causes the generation of
12589 spureous additional errors.
12591 * exp_dbug.ads (Pointers to Unconstrained Arrays): Document the
12592 debugging information now generated by the compiler for fat-pointer
12594 Document the contents of DW_AT_producer in the GNAT Vendor extensions to
12596 Document GNAT Vendor extensions to DWARF 2/3 and the "-gdwarf+" switch.
12598 2007-06-06 Thomas Quinot <quinot@adacore.com>
12600 * exp_dist.ads, exp_dist.adb (Make_Transportable_Check): New subprogram

12602 PolyORB_Support.Build_Subprogram_Receiving_Stubs):
12603 For a remote call to a function with a classwide return type, apply an
12604 E.4(18) check to the returned value.
12605 (Add_RACW_Primitive_Declarations_And_Bodies): Do not generate stubs for
12606 stream attributes of the designated type of an RACW, as they are not
12607 dispatching primitive operations.
12609 2007-06-06 Geert Bosch <bosch@adacore.com>
12611 * exp_fixd.adb (Integer_Literal): Add optional argument to construct a
12613 (Do_Divide_Fixed_Fixed): Add comments to indicate Frac is always
12615 (Do_Divide_Fixed_Universal): Handle case of negative Frac.
12616 (Do_Multiply_Fixed_Fixed): Add coments to indicate Frac is always
12618 (Do_Multiply_Fixed_Universal): Handle case of negative Frac.
12620 2007-06-06 Javier Miranda <miranda@adacore.com>
12622 * exp_imgv.adb (Expand_Value_Attribute): Disable compilation of this
12623 attribute compiling package Ada.Tags under No_Run_Time_Mode.
12625 2007-06-06 Javier Miranda <miranda@adacore.com>
12627 * exp_intr.adb (Expand_Unc_Deallocation): Add missing support for
12628 deallocation of class-wide interface objects.
12629 (Expand_Dispatching_Constructor_Call): Take into account that if the
12630 result of the dispatching constructor is an interface type, the
12631 function returns a class-wide interface type; otherwise the returned
12632 object would be actual. The frontend previously accepted returning
12633 interface types because Expand_Interface_Actuals silently performed
12634 the management of the returned type "as if" it were a class-wide
12636 (Expand_Dispatching_Constructor_Call): Replace call to
12637 Make_DT_Access_Action by direct call to Make_Function_Call.
12639 2007-06-06 Robert Dewar <dewar@adacore.com>
12640 Ed Schonberg <schonberg@adacore.com>
12642 * exp_pakd.adb (Expand_Packed_Not): Use RM_Size rather than ESize to
12643 compute masking constant, since we now set Esize properly to the
12645 (Create_Packed_Array_Type): Set proper Esize value adjusted as required
12646 to match the alignment.
12647 (Create_Packed_Array_Type): Use Short_Short_Unsigned as base type for
12648 packed arrays of 8 bits or less.
12650 * freeze.adb (Freeze_Entity): When freezing the formals of a
12651 subprogram, freeze the designated type of a parameter of an access type
12652 only if it is an access parameter.
12653 Increase size of C convention enumeration object
12654 (Freeze_Entity, array type case): Make sure Esize value is properly
12655 adjusted for the alignment if it is known.
12656 (Freeze_Entity, array type case): When checking bit packed arrays for
12657 the size being incorrect, check RM_Size, not Esize.
12658 (Freeze_Record_Type): Check for bad discriminated record convention
12659 (In_Exp_Body): Return true if the body is generated for a subprogram
12660 renaming, either an attribute renaming or a renaming as body.
12661 (Check_Itype): If the designated type of an anonymous access component
12662 is a non-protected subprogram type, indicate that it is frozen, to
12663 prevent out-of-scope freeze node at some subsequent call.
12664 (Freeze_Subprogram): On OpenVMS, reject descriptor passing mechanism
12665 only if the subprogram is neither imported nor exported, as well as the
12666 NCA descriptor class if the subprogram is exported.

12670 Robert Dewar <dewar@adacore.com>
12671 Gary Dismukes <dismukes@adacore.com>
12673 * exp_prag.adb (Expand_Pragma_Import_Or_Interface): Remove properly a
12674 default initialization on an imported object, when there is no
12675 initialization call generated for it.
12676 (Expand_Pragma_Assert): Add handling of No_Exception_Propagation
12679 * snames.h, snames.ads, snames.adb, par-prag.adb: New pragma
12680 Static_Elaboration_Desired.
12681 Remove pragma Thread_Body.

12686 (Name_CIL, Name_CIL_Constructor, Convention_CIL,
12687 Pragma_CIL_Constructor): New names.
12689 * sem_cat.adb (Validate_Object_Declaration): An initialization that
12690 uses the equivalent aggregate of a type must be treated as an implicit

12693 has none of the other categories.
12694 (Process_Import_Or_Interface_Pragma): Report an error for an attempt
12695 to apply Import to an object renaming declaration.
12697 * sem_prag.adb (Process_Import_Or_Interface): Warn that a type imported
12698 from a C++ class should be declared as limited and that it will be
12699 considererd limited.
12700 (Analyze_Pragma): Warn that a type specified with pragma CPP_Class
12701 should be declared as limited and that it will be considererd limited.
12702 (Ada_2005_Pragma): New procedure, used to deal with Ada 2005 pragmas
12703 (Analyze_Pragma, case Export): Diagnose export of enumeration literal
12704 (Analyze_Pragma): Deal with Universal_Aliasing.

12725 * exp_util.ads, exp_util.adb (Expand_Subtype_From_Expr): In Ada2005, an
12726 object of a limited type can be initialized with a call to a function
12727 that returns in place. If the limited type has unknown discriminants,
12728 and the underlying type is a constrained composite type, build an actual
12729 subtype from the function call, as is done for private types.
12730 (Side_Effect_Free): An expression that is the renaming of an object or
12731 whose prefix is the renaming of a object, is not side-effect free
12732 because it may be assigned through the renaming and its value must be
12733 captured in a temporary.
12734 (Has_Controlled_Coextensions): New routine.
12735 (Expand_Subtype_From_Expr): Do nothing if type is a limited interface,
12736 as is done for other limited types.

12747 the parent unit is a renaming when the parent is itself a child unit.
12748 Remove handling of with_type clauses.
12750 * sinfo.ads, sinfo.adb (Is_Static_Coextension): New function.

12786 Add new warning for renaming of function return objects
12788 * opt.adb (Tree_Write, Tree_Read): Use proper expressions for size
12789 (Tree_Read): Use size of object instead of type'object_size, since the
12790 latter is incorrect for packed array types.
12791 (Tree_Write): Same fix
12793 * opt.ads: Add new warning for renaming of function return objects
12794 (Generating_Code): New boolean variable used to indicate that the

12806 * sem_ch8.adb (Check_Library_Unit_Renaming): Check that the renamed
12807 unit is a compilation unit, rather than relying on its scope, so that
12808 Standard can be renamed.
12809 (Analyze_Object_Renaming): Add new warning for renaming of function
12811 Also reject attempt to rename function return object in Ada 83 mode.
12812 (Attribute_Renaming): In case of tagged types, add the body of the
12813 generated function to the freezing actions of the type.
12814 (Find_Type): A protected type is visible right after the reserved word
12815 "is" is encountered in its type declaration. Set the entity and type
12816 rather than emitting an error message.
12817 (New_Scope): Properly propagate Discard_Names to inner scopes

12834 absolute value of Header.Block_Size when displaying the freed physical
12836 (Allocate): Compute Storage_Address using Integer_Address, not
12837 Storage_Offset, because the range of Storage_Offset may not be large
12839 (Configure): New parameter Low_Level_Traces
12840 (Allocate, Deallocation, Free_Physically): Added low-level traces
12841 (Configure): new parameter Errors_To_Stdout.

12843 (Deallocate, Dereference): Send error messages to the proper stream
12844 (Print_Pool, Print_Info_Stdout): Make sure the output goes to stdout, as
12845 documented. Previous code would send it to the current output file
12846 defined in GNAT.IO, which might not be stdout
12847 (Is_Valid): Adjust comment to mention that a positive reply means that
12848 Header_Of may be used to retrieve the allocation header associated with
12849 the subprogram Storage address argument. Return False early if this
12850 address argument is misaligned.
12852 2007-06-06 Vincent Celier <celier@adacore.com>

12866 * gnatlink.adb (Gnatlink): Do not specify -static-libgcc when --LINK=
12868 Correct error message when invocation of the linker fails
12869 Add explicit size clause for the C imported variables
12870 Object_List_File_Supported and Using_GNU_Linker to emphasize that
12871 we expect char size.
12872 Read target parameters earlier, since this is needed to set
12873 Target_VM properly. Also do not use -static/shared-libgcc for non GCC
12876 2007-06-06 Vincent Celier <celier@adacore.com>
12879 Add 3 spaces before the default project directory when displaying
12880 the project search path.
12881 Add new command line switch '-l' to display license information.

13257 associated with dispatch tables is known at compile time.
13258 (Get_Value): If an association in a record aggregate has a box
13259 association, and the corresponding record component has a default
13260 expression, always copy the default expression, even when the

14361 parameter, to handle an Ada 2005 syntactic ambiguity for calls written
14363 (Resolve_Actuals): If an actual is an allocator for an access parameter,
14364 the master of the created object is the innermost enclosing statement.
14365 (Remove_Conversions): For a binary operator, check if type of second

14608 attempt to derive from a synchronized tagged type.

14613 that use (a subtype of) the class-wide type of the enclosing type.

14616 Check_Anonymous_Access_Components rather than Empty.
14617 (Make_Incomplete_Type_Declaration): Add test for case where the type has
14618 a record extension in deciding whether to create a class-wide type,

14673 (Initialize): Add the directory where gnatmake is invoked in front of
14674 the path if it is invoked from a bin directory, even without directory

14698 * par.adb: Allow library units Calendar, Machine_Code,
14699 Unchecked_Conversion and Unchecked_Deallocation to be recompiled even
14700 when -gnatg is not specified.
14701 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
14702 there is no need to generate always a record_definition_node in case
14703 of synchronized interface types.
14704 (SIS_Entry_Active): Initialize global variable to False
14705 (P_Null_Exclusion): For AI-447: Add parameter Allow_Anonymous_In_95 to
14706 indicate cases where AI-447 says "not null" is legal.
14708 * makeutl.ads, makeutil.adb (Executable_Prefix_Path): New function
14710 * makegpr.adb (Check_Compilation_Needed): Take into account dependency
14711 files with with several lines starting with the object fileb name.

14714 (Initialize): Add the directory where gprmake is invoked in front of the
14715 path, if it is invoked from a bin directory or with directory
14716 information, so that the correct GNAT tools will be used when invoked

14726 If the array component is a discriminated record, the array aggregate
14727 is non-static even if the component is given by an aggregate with
14729 (Expand_Record_Aggregate): Use First/Next_Component_Or_Discriminant
14730 (Convert_Aggr_In_Allocator): If the allocator is for an access
14731 discriminant and the type is controlled. do not place on a finalization
14732 list at this point. The proper list will be determined from the
14734 (Build_Record_Aggr_Code): If aggregate has box-initialized components,
14735 initialize record controller if needed, before the components, to ensure
14736 that they are properly finalized.
14737 (Build_Record_Aggr_Code): For the case of an array component that has a
14738 corresponding array aggregate in the record aggregate, perform sliding

14749 accessibility on class-wide allocators if the allocator occurs at the
14750 same scope level as the allocator's type. The check is guaranteed to
14751 succeed in that case, even when the expression originates from a
14752 parameter of the containing subprogram.
14753 (Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
14754 under No_Dispatching_Calls restriction. During the semantic analysis
14755 we already notified such violation.
14756 (Tagged_Membership): Constant folding. There is no need to check
14757 the tag at run-time if the type of the right operand is non
14758 class-wide abstract.

14772 * exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
14773 initialize most the TSD components by means of an aggregate.
14774 Modify the declaration of the object containing the TSD
14775 because we now expand code that has a higher level of abstraction.
14776 The TSD has a discriminant containing the Inheritance Depth Level,
14777 value that is used in the membership test but also to fix the size
14778 of the table of ancestors.
14779 (Expand_Interface_Conversion): Insert function body at the closest place
14780 to the conversion expression, to prevent access-before-elaboration
14781 errors in the backend.

14783 compiling under restriction No_Dispatching_Calls plus code cleanup.
14784 Code reorganization plus removal of calls to Set_Num_Prim_Ops
14785 (Make_Secondary_DT): Remove call to Set_Num_Prim_Ops.

14806 Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
14807 (Expand_Dispatching_Call): Replace generation of call to the run-time
14808 subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
14809 calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
14811 (Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
14812 the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_

14814 Build_Set_Prim_Op_Address.
14815 (Get_Remotely_Callable): Subprogram removed.
14816 (Init_Predefined_Interface_Primitives): Replace generation of call to
14817 the run-time subprograms Inherit_DT by call to Build_Inherit_Predefined_
14820 * sem_elab.adb (Set_Elaboration_Constraint): Replace the call to
14821 First (Parameter_Associations ()) with the call to First_Actual that
14822 returns an actual parameter expression for both named and positional
14825 * sem_disp.adb (Check_Dispatching_Call): In case of dispatching call
14826 check violation of restriction No_Dispatching_Calls.
14827 (Check_Controlling_Type): A formal of a tagged incomplete type is a
14828 controlling argument.

14831 First/Next_Component_Or_Discriminant
14832 (Insert_Actions): Add entries for new N_Push and N_Pop nodes
14833 (Find_Implemented_Interface): Removed. All the calls to this subprogram
14834 specify Any_Limited_Interface, and this functionality is already
14835 provided by the function Has_Abstract_Interfaces.
14836 (Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
14837 support concurrent types implementing interfaces.
14838 (Find_Implemented_Interface): Removed. All the calls to this subprogram
14839 specify kind Any_Limited_Interface, and this functionality is already
14840 provided by the function Has_Abstract_Interfaces.
14841 (Remove_Side_Effects): replace Controlled_Type by
14842 CW_Or_Controlled_Type whenever the issue is related to
14843 using or not the secondary stack.
14845 * par-ch12.adb (P_Formal_Type_Definition): Update calls to
14846 P_Interface_Type_Definition to fulfill the new interface (the formal
14847 Is_Synchronized is no longer required).

14859 anonymous, use finalization list of enclosing dynamic scope.
14860 (Expand_N_Package_Declaration): For a library package declaration
14861 without a corresponding body, generate RACW subprogram bodies in the
14862 spec (just as we do for the task activation call).
14863 (Convert_View): Split Is_Abstract flag into Is_Abstract_Subprogram and
14864 Is_Abstract_Type. Make sure these are called only when appropriate.
14865 Remove all code for DSP option
14866 (CW_Or_Controlled_Type): new subprogram.

14872 * exp_ch9.ads, exp_ch9.adb (Family_Offset): Add new 'Cap' boolean
14873 parameter. If it is set to true, return a result capped according to
14874 the global upper bound for the index of an entry family.
14875 (Family_Size): Add new 'Cap' boolean parameter. Pass it to Family_Offset
14876 (Build_Find_Body_Index): Adjust for above change.
14877 (Entry_Index_Expression): Likewise.
14878 (Is_Potentially_Large_Family): New function extracted from...

14882 Family_Size with 'Cap' set to true.
14883 (Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
14884 a protected version of an operation declared in the private part of
14885 a protected object, because they may be invoked through a callback.
14886 (Set_Privals): If the type of a private component is an anonymous access
14887 type, do not create a new itype for each protected body.
14888 If the body of a protected operation creates
14889 controlled types (including allocators for class-widetypes), the
14890 body of the corresponding protected subprogram must include a
14892 (Build_Activation_Chain_Entity): Build the chain entity for extended
14894 (Type_Conformant_Parameters): Use common predicate Conforming_Types
14895 to determine whether operation overrides an inherited primitive.

14897 for a possible overriding candidate.
14898 (Build_Simple_Entry_Call): Set No_Initialization on the object used to
14899 hold an actual parameter value since its initialization is separated
14900 from the the declaration. Prevents errors on null-excluding access

14904 Pablo Oliveira <oliveira@adacore.com>
14906 * exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
14907 Do an Unchecked_Conversion to handle the passage from the Underlying
14908 Type to the Base Type when calling Build_To_Any_Call and
14909 Build_From_Any_Call.
14910 (Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
14911 E_Constant, depending upon Variable formal.
14912 (GARLIC_Support.Build_Subprogram_Receiving_Stubs,
14913 PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
14914 parameter that requires an extra constrained parameter, declare
14915 temporary for actual as a variable, not a constant.
14916 (Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
14917 the unit being compiled is the one that contains the stub type.
14918 Change primitive operation name for the RACW associated with a RAS
14919 from Call to _Call so it cannot clash with any legal identifier.
14920 (PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
14922 (Append_RACW_Bodies): New subprogram.
14923 (Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
14924 Add_Receiving_Stubs_To_Declarations functions.
14925 When expanding a package body, this list correspond to the
14926 statements in the HSS at the end of the pacakge.
14927 When expanding a package spec, this list correspond to the

14930 registering the receiving stubs at the end of the 'Stmts' list.
14931 (RCI_Package_Locator): Pass the new Version generic formal when
14932 instantiating a RCI_Locator package.
14933 (Build_From_Any_Function): To compute the High bound for an
14934 unconstrained array actual, we add the Low bound with the length.
14935 Thus we must convert the low bound and the length to an appropriate
14936 type before doing the sum.
14937 (Build_Subprogram_Receiving_Stubs, PolyORB):
14938 * Retrieve the extra formals parameters at the
14939 end of the parameter stream.
14940 * Use Move_Any_Value to write back out parameters
14941 after executing the request as it is more efficient
14942 than Copy_Any_Value.
14943 * Build the any containing Extra Formals with the
14944 appropriate typecode.
14945 (PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
14946 empty Component_List.
14947 (Build_Actual_Object_Declaration): New subprogram. Build and insert into
14948 the tree the declaration for an object that serves as actual parameter
14949 in server-side stubs.

14959 function with the first not implicit parent type.
14960 (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
14961 (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
14962 typecode from the Etype. Therefore we retrieve the correct typecode
14963 with a call to Get_Any_Type.
14964 (Copy_Specification): Do controlling formal type substitution based on
14965 Is_Controlling_Formal flag, instead of caller-provided object type.
14966 (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
14967 a RACW primitive operation, we might get a subprogram declaration for an
14968 ancestor of the RACW designated type (not for the designated type
14969 itself), in the case where this operation is inherited. In this case we
14970 have no easy means of determining the original tagged type for which
14971 the primitive was declared, so instead we now rely on
14972 Copy_Specification to use the Is_Controlling_Formal flag to determine
14973 which formals require type substitution.

14979 GNAT.Current_Exception are not allowed if pragma Restrictions
14980 (No_Exception_Propagation) is set and in any case make the associated
14981 handler unsuitable as a target for a local raise statement.
14982 (Expand_Dispatching_Constructor_Call): Replace generation of call to the
14983 run-time subprogram CW_Membership by call to Build_CW_Membership.
14984 (Expand_Dispatching_Constructor_Call): If the dispatching tag is given
14985 by a function call, a temporary must be created before expanding the
14986 Constructor_Call itself, to prevent out-of-order elaboration in the
14987 back-end when stack checking is enabled..
14989 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14991 * exp_pakd.adb (Expand_Packed_Boolean_Operator): The bounds of the
14992 result are the bounds of the left operand, not the right.
14994 2007-04-06 Ed Schonberg <schonberg@adacore.com>
14997 (Build_Mutable_Record_Write_Procedure): For an Unchecked_Union type, use

15114 * mingw32.h (S2WSU): New macro to convert from a string to a
15115 wide-string using the UTF-8 encoding. The S2WS macro supports now only
15116 standard 8bits encoding.
15117 (WS2SU): As above but converting from wide-sring to string.
15118 This is needed as it is necessary to have access to both versions in the
15119 runtime for the form parameter encoding support.
15120 This set of patch add support for the encoding form parameter.
15121 (S2WS): Improve implementation to handle cases where the filename is not
15122 UTF-8 encoded. In this case we default to using the current code page
15123 for the conversion.
15125 * s-crtl-vms64.ads, s-crtl.ads (Filename_Encoding): New enumeration
15126 type (UTF8, ASCII_8bits). This enumeration has a rep clause to match

15170 * init.c: Reuse PA/HP-UX code for IA-64/HP-UX, except
15171 __gnat_adjust_context_for_raise.
15172 (__gnat_init_float): on x86 vxworks 5.x and 6.x, we use the same
15173 implementation of floating point operations as native x86 targets.
15174 So the FPU should be initialized in the same way using finit. Fix
15175 floating point operations accuracy issues.
15176 (__gnat_install_handler, case FreeBSD): Use proper type for sa_sigaction
15177 member in struct sigaction, so as to avoid warning for incompatible

15195 * lib-xref.ads, lib-xref.adb:
15196 Modify the loop that collects type references, to include interface
15197 types that the type implements. List each of these interfaces when
15198 building the entry for the type.
15199 (Generate_Definition): Initialize component Def and Typ of new entry
15200 in table Xrefs, to avoid to have these components unitialized.
15201 (Output_References): Split Is_Abstract flag into
15202 Is_Abstract_Subprogram and Is_Abstract_Type.

15244 2007-04-06 Robert Dewar <dewar@adacore.com>
15246 * namet.ads, namet.adb (wn): Improve this debugging routine. Calling
15247 it no longer destroys the contents of Name_Buffer or Name_Len and
15248 non-standard and invalid names are handled better.
15249 (Get_Decoded_Name_String): Improve performance by using
15250 Name_Has_No_Encodings flag in the name table.
15251 (Is_Valid_Name): New function to determine whether a Name_Id is valid.
15252 Used for debugging printouts.

15256 Bob Duff <duff@adacore.com>
15258 * par-ch3.adb: (P_Type_Declaration): Set Type_Token_Location
15259 (P_Interface_Type_Definition): Remove the formal Is_Synchronized because
15260 there is no need to generate always a record_definition_node in case
15261 of synchronized interface types.
15262 (P_Type_Declaration): Update calls to P_Interface_Type_Definition.
15263 (P_Null_Exclusion): For AI-447: Remove warnings about "not null" being
15264 illegal in Ada 95, in cases where it is legal. Change the warnings to
15265 errors in other cases. Don't give the error unless the "not null"
15266 parses properly. Correct the source position at which the error occurs.
15267 (P_Known_Discriminant_Part_Opt): Pass Allow_Anonymous_In_95 => True to
15268 P_Null_Exclusion, to suppress "not null" warnings.

15320 Entry for pragma Unreferenced_Objects
15322 * switch-c.adb (Scan_Front_End_Switches): Store correct -gnateD
15323 switches, without repetition of "eD". Make sure that last character of
15324 -gnatep= switch is not taken as -gnat switch character.
15325 Complete rewrite of circuit for handling saving compilation options

15344 the default project path, initially done during elaboration of the
15346 If the prefix returned by Sdefault is null, get the prefix from a call
15347 to Executable_Prefix_Path.
15348 (Project_Path): Call Initialize_Project_Path if Current_Project_Path is
15351 * prj-nmsc.adb (Get_Path_Names_And_Record_Sources): Use the non
15352 canonical directory name to open the directory from which files are
15354 (Record_Other_Sources): Idem.
15355 (Locate_Directory): Add the possibility to create automatically missing
15356 directories when Setup_Projects is True.
15357 Call Locate_Directory so that the directory will be created when
15358 Setup_Projects is True, for object dir, library dir, library ALI dir,
15359 library source copy dir and exec dir.
15361 * prj-pp.adb (Max_Line_Length): Set to 255 for compatibility with older
15364 2007-04-06 Robert Dewar <dewar@adacore.com>

15399 full word is no longer compared twice.
15401 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15403 * sem_ch10.adb (Install_Limited_Context_Clauses.
15404 Expand_Limited_With_Clause): Use a new copy of selector name in the
15405 call to Make_With_Clause. This fixes the tree structure for ASIS
15406 purposes. Nothing is changed in the compiler behaviour.
15407 (Process_Body_Clauses): Handle properly use clauses whose prefix is
15408 a package renaming.
15409 (Install_Limited_With_Clauses): Do not install non-limited view when it
15410 is still incomplete.
15412 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15413 Gary Dismukes <dismukes@adacore.com>
15415 * sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
15416 when capturing size information, instead of base type, which for a
15417 formal array type will be the unconstrained type.
15418 (Analyze_Formal_Object_Declaration): Add check for illegal default
15419 expressions for a formal in object of a limited type.
15420 (Instantiate_Object): Ditto.
15421 (Check_Formal_Package_Instance): Skip entities that are formal objects,
15422 because they were defaulted in the formal package and no check applies
15424 (Check_Formal_Package_Instance): Extend conformance check to other
15425 discrete types beyond Integer.
15426 (Process_Default): Copy directly the unmatched formal. A generic copy
15427 has already been performed in Analyze_Formal_Package.
15428 (Analyze_Associations): If a formal subprogram has no match, check for
15429 partial parametrization before looking for a default, to prevent
15431 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
15432 not set the instantiation environment before analyzing the actuals.
15433 Fixes regression on 8515-003 with implementation of AI-133.
15434 Set_Instance_Env checks whether the generic unit is a predefined
15435 unit, in which case the instance must be analyzed with the latest Ada
15436 mode. This setting must take place after analysis of the actuals,
15437 because the actuals must be analyzed and frozen in the Ada mode extant
15438 outside of the current instantiation.
15439 (Save_Env, Restore_Env): Preserve and restore the configuration
15440 parameters so that predefined units can be compiled in the proper Ada
15442 (Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
15443 Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram
15444 and Is_Abstract_Type.
15445 (Analyze_Formal_Package): For better error recovery, Add exception
15446 handler to catch Instantion_Error, which can be raised in
15447 Analyze_Associations
15449 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15450 Bob Duff <duff@adacore.com>
15451 Gary Dismukes <dismukes@adacore.com>
15453 * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
15454 prefix type is a discriminated subtype of the type of the formal.
15455 (Analyze_Allocator): Collect all coextensions regardless of the context.
15456 Whether they can be allocated statically is determined in exp_ch4.
15457 (Analyze_Selected_Component): If the prefix is a limited view and the
15458 non-limited view is available, use the non-limited one.
15459 (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
15460 therefore illegal), suggest a qualified expression rather than a type
15461 conversion, because a type conversion would be illegal in this context.
15462 (Anayze_Allocator): Trace recursively all nested allocators so that all
15463 coextensions are on the corresponding list for the root. Do no mark
15464 coextensions if the root allocator is within a declaration for a stack-
15465 allocated object, because the access discriminants will be allocated on
15467 (Analyze_Call): Remove restriction on calls to limited functions for the
15468 cases of generic actuals for formal objects, defaults for formal objects
15469 and defaults for record components.
15470 (Analyze_Allocator): Before analysis, chain coextensions on the proper
15471 element list. Their expansion is delayed until the enclosing allocator
15472 is processed and its finalization list constructed.
15473 (Try_Primitive_Operation): If the prefix is a concurrent type, looks
15474 for an operation with the given name among the primitive operations of
15475 the corresponding record type.
15476 (Analyze_Selected_Component): If the prefix is a task type that
15477 implements an interface, and there is no entry with the given name,
15478 check whether there is another primitive operation (e.g. a function)
15480 (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
15481 properly the indexing of a function call written in prefix form, where
15482 the function returns an array type, and all parameters of the function
15483 except the first have defaults.
15484 (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
15485 the original operands, rather than relocating them, for efficiency and
15486 to work properly when an operand is overloaded.
15487 (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
15488 Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
15489 (Analyze_Selected_Component): If the prefix is a private extension, only
15490 scan the visible components, not those of the full view.
15491 (Try_Primitive_Operation): If the operation is a procedure, collect all
15492 possible interpretations, as for a function, because in the presence of
15493 classwide parameters several primitive operations of the type can match
15494 the given arguments.
15496 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15497 Robert Dewar <dewar@adacore.com>
15499 * sem_ch5.adb (Analyze_Assignment): Reject a right-hand side that is a
15500 tag-indeterminate call to an abstract function, when the left-hand side
15502 (Analyze_Loop_Statement): Improve detection of infinite loops
15504 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15505 Thomas Quinot <quinot@adacore.com>
15507 * sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
15508 out of Analyze_Package_Declaration, because processing must be applied
15509 to package bodies as well, for deferred constants completed by pragmas.
15510 (Analyze_Package_Declaration): When the package declaration being
15511 analyzed does not require an explicit body, call Check_Completion.
15512 (May_Need_Implicit_Body): An implicit body is required when a package
15513 spec contains the declaration of a remote access-to-classwide type.
15514 (Analyze_Package_Body): If the package contains RACWs, append the
15515 pending subprogram bodies generated by exp_dist at the end of the body.
15516 (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
15517 Is_Abstract_Subprogram and Is_Abstract_Type.
15518 (Preserve_Full_Attributes): The full entity list is not an attribute
15519 that must be preserved from full to partial view.
15521 * sem_dist.adb (Add_RAS_Dereference_TSS):
15522 Change primitive name to _Call so it cannot clash with any legal
15523 identifier, and be special-cased in Check_Completion.
15524 Mark the full view of the designated type for the RACW associated with
15525 a RAS as Comes_From_Source to get proper view switching when installing
15526 private declarations.
15527 Provite a placeholder nested package body along with the nested spec
15528 to have a place for Append_RACW_Bodies to generate the calling stubs
15529 and stream attributes.
15531 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15532 Robert Dewar <dewar@adacore.com>
15534 * sem_ch8.adb (Has_Components): If the argument is an incomplete type
15535 that is a limited view, check the non-limited view if available.
15536 (Undefined): Refine error message for missing with of Text_IO
15537 (Find_Expanded_Name): Use Is_Known_Unit for more accurate error message
15538 to distinguish real missing with cases.
15539 Fix format of all missing with messages
15540 (Analyze_Subprogram_Renaming): Emit proper error message on illegal
15541 renaming as body when renamed entity is abstract.
15543 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15544 Javier Miranda <miranda@adacore.com>
15546 * sem_type.ads, sem_type.adb (Has_Abstract_Interpretation): Make
15547 predicate recursive, to handle complex expressions on literals whose
15548 spurious ambiguity comes from the abstract interpretation of some
15550 (Interface_Present_In_Ancestor): Add support to concurrent record
15552 (Add_One_Interp,Disambiguate): Split Is_Abstract flag into
15553 Is_Abstract_Subprogram and Is_Abstract_Type.
15555 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15556 Javier Miranda <miranda@adacore.com>
15558 * sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
15559 dereference of a local object R created as a reference to another
15560 object O, use the access level of O.
15561 (Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
15562 rather than local Same_Formal_Type, to check whether protected operation
15563 overrides an inherited one.
15564 (Same_Formal_Type): New predicate, used when matching signatures of
15565 overriding synchronized operations, to handle the case when a formal
15566 has a type that is a generic actual.
15567 (Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
15568 predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
15569 (Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
15570 syntactic ambiguities involving indexing of function calls that return
15572 (Abstract_Interface_List): New subprogram that returns the list of
15573 abstract interfaces associated with a concurrent type or a
15574 concurrent record type.
15575 (Interface_Present_In_Parent): New subprogram used to check if a
15576 given type or some of its parents implement a given interface.
15577 (Collect_Abstract_Interfaces): Add support for concurrent types
15578 with interface types.
15579 (Has_Abstract_Interfaces): Add support for concurrent types with
15581 (Is_Parent): New subprogram that determines whether E1 is a parent
15582 of E2. For a concurrent type its parent is the first element of its
15583 list of interface types; for other types this function provides the
15584 same result than Is_Ancestor.
15585 (Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
15586 (Collect_Synchronized_Interfaces): Removed because the subprogram
15587 Collect_Abstract_Interfaces provides this functionality.
15588 (Collect_Abstract_Interfaces): Minor update to give support to
15589 concurrent types and thus avoid undesired code duplication.
15590 (Get_Subprogram_Entity): Handle entry calls.
15591 (May_Be_Lvalue): Include actuals that appear as in-out parameters in
15593 (Enter_Name): Do not give -gnatwh hiding warning for record component
15594 entities, they never result in hiding.
15596 2007-04-06 Ed Schonberg <schonberg@adacore.com>
15597 Robert Dewar <dewar@adacore.com>
15599 * sinfo.ads, sinfo.adb (Coextensions): New element list for allocators,
15600 to chain nested components that are allocators for access discriminants
15601 of the enclosing object.
15602 Add N_Push and N_Pop nodes

15924 anonymous access types.
15925 (Valid_Conversion): For a conversion to a numeric type occurring in an
15926 instance or inlined body, no need to check that the operand type is

16497 by themselves. Disabling those checks must also be done for task types,
16498 where discriminants may be used for the bounds of entry families.
16499 (Apply_Address_Clause_Check): Remove side-effects if address expression
16500 is non-static and is not the name of a declared constant.

16512 rewritten replacement for Apply_Alignment_Check
16513 (Get_E_Length/Get_E_First_Or_Last): Add missing barrier to ensure that
16514 we request a discriminal value only in case of discriminants.
16515 (Apply_Discriminant_Check): For Ada_05, only call Get_Actual_Subtype for
16516 assignments where the target subtype is unconstrained and the target
16517 object is a parameter or dereference (other aliased cases are known
16518 to be unconstrained).

16632 the parent part is a build-in-place function call, generate assignments.
16633 (Expand_Record_Aggregate): Call Convert_To_Assignments if any components
16634 are build-in-place function calls.
16635 (Replace_Self_Reference): New subsidiary of
16636 Make_OK_Assignment_Statement, to replace an access attribute that is a
16637 self-reference into an access to the appropriate component of the
16638 target object. Generalizes previous mechanism to handle self-references
16639 nested at any level.
16640 (Is_Self_Referential_Init): Remove, not needed.
16641 (Is_Self_Referential_Init): New predicate to simplify handling of self
16642 referential components in record aggregates.

16644 check for presence of entity before checking for self-reference.
16645 (Has_Default_Init_Comps): Return True if a component association is a
16646 self-reference to the enclosing type, which can only come from a
16647 default initialization.
16648 (Make_OK_Assignment_Statement): If the expression is of the form
16649 Typ'Acc, where Acc is an access attribute, the expression comes from a
16650 default initialized self-referential component.
16651 (Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
16652 that has been derived from several abstract interfaces we must also
16653 initialize the tags of the secondary dispatch tables.

16658 Robert Dewar <dewar@adacore.com>
16661 (Expand_Access_To_Protected_Op): If the context indicates that an access
16662 to a local operation may be transfered outside of the object, create an
16663 access to the wrapper operation that must be used in an external call.
16664 (Expand_N_Attribute_Reference, case Attribute_Valid): For the AAMP
16665 target, pass the Valid attribute applied to a floating-point prefix on
16666 to the back end without expansion.
16667 (Storage_Size): Use the new run-time function Storage_Size to retrieve
16668 the allocated storage when it is specified by a per-object expression.
16669 (Expand_N_Attribute_Reference): Add case for Attribute_Stub_Type.
16670 Nothing to do here, the attribute has been rewritten during semantic

16679 into a fat pointer.
16680 (Is_Constrained_Aliased_View): New predicate to help determine whether a
16681 subcomponent's enclosing variable is aliased with a constrained subtype.
16682 (Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
16683 test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
16684 an aliased prefix must be known to be constrained in order to use True
16685 for the attribute value, and now it's possible for some aliased views
16686 to be unconstrained.
16688 2006-10-31 Robert Dewar <dewar@adacore.com>
16690 * exp_ch2.adb: Change Is_Lvalue to May_Be_Lvalue
16691 (Expand_Entity_Reference): Correct error of not handling subprogram
16692 formals in current_value processing.

16697 Gary Dismukes <dismukes@adacore.com>
16699 * exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
16700 register in the final list objects containing class-wide interfaces;
16701 otherwise we incorrectly register the tag of the interface in the final
16703 (Make_Controlling_Function_Wrappers): Add missing barrier to do not
16704 generate the wrapper if the parent primitive is abstract. This is
16705 required to report the correct error message.
16706 (Expand_N_Subtype_Indication): Do validity checks on range
16707 (Clean_Task_Names): If an initialization procedure includes a call to
16708 initialize a task (sub)component, indicate that the procedure will use
16709 the secondary stack.
16710 (Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
16711 compatibility for interfacing with CPP by default.
16712 (Expand_N_Object_Declaration): Only build an Adjust call when the
16713 object's type is a nonlimited controlled type.
16714 * exp_ch3.adb: Add with and use of Exp_Ch6.
16715 (Expand_N_Object_Declaration): Check for object initialization that is a
16716 call to build-in-place function and apply Make_Build_In_Place_Call_In_
16717 Object_Declaration to the call.
16718 (Freeze_Type): When the designated type of an RACW was not frozen at the
16719 point where the RACW was declared, validate the primitive operations
16720 with respect to E.2.2(14) when it finally is frozen.
16721 (Build_Initialization_Call,Expand_Record_Controller): Rename
16722 Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
16723 return-by-reference has no meaning in Ada 2005.
16724 (Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
16725 to register tag of the immediate ancestor interfaces in the
16726 run-time structure.
16727 (Init_Secondary_Tags): Moved to the specification to allow the
16728 initialization of extension aggregates with abstract interfaces.
16729 (Build_Master_Renaming): Make public, for use by function declarations
16730 whose return type is an anonymous access type.
16731 (Freeze_Record_Type): Replace call to Insert_List_Before by call to
16732 Insert_List_Before_And_Analyze after the generation of the specs
16733 associated with null procedures.
16734 (Expand_Tagged_Root): Update documentation in its specification.
16735 (Init_Secondary_Tags): Update documentation.
16736 (Build_Init_Procedure): If we are compiling under CPP full ABI compa-
16737 tibility mode and the immediate ancestor is a CPP_Pragma tagged type
16738 then generate code to inherit the contents of the dispatch table
16739 directly from the ancestor.
16740 (Expand_Record_Controller): Insert controller component after tags of
16741 implemented interfaces.
16742 (Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
16743 create null procedure overridings when null procedures are inherited

16746 declarations for overriding null primitives inherited from interfaces.
16747 (Is_Null_Interface_Procedure): New function in
16748 Make_Null_Procedure_Specs.
16749 (Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
16750 immediate ancestor of a tagged type is an abstract interface type we
16751 must generate the specification of the predefined primitives associated
16752 with controlled types (because the dispatch table of the ancestor is
16753 null and hence these entries cannot be inherited). This is required to
16754 elaborate well the dispatch table.

16764 (Expand_N_In): Do validity checks on range
16765 (Expand_Selected_Component): Use updated for of Denotes_Discriminant.
16766 (Expand_N_Allocator): For "new T", if the object is constrained by
16767 discriminant defaults, allocate the right amount of memory, rather than
16768 the maximum for type T.
16769 (Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
16770 when the allocator is initialized by a build-in-place call, since the
16771 allocator is already rewritten as a reference to the function result,
16772 and this prevents an unwanted duplication of the function call.
16773 Add with and use of Exp_Ch6.
16774 (Expand_Allocator_Expresssion): Check for an allocator whose expression
16775 is a call to build-in-place function and apply
16776 Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and
16777 untagged designated types).
16778 (Expand_N_Unchecked_Type_Conversion): Do not do integer literal
16779 optimization if source or target is biased.
16780 (Expand_N_Allocator): Add comments for case of an allocator within a
16781 function that returns an anonymous access type designating tasks.
16782 (Expand_N_Allocator): apply discriminant checks for access
16783 discriminants of anonymous access types (AI-402, AI-416)

16792 * exp_ch5.adb (Expand_N_Loop_Statement): Do validity checks on range
16793 (Expand_N_Assignment_Statement): Call
16794 Make_Build_In_Place_Call_In_Assignment if the right-hand side is a
16795 build-in-place function call. Currently, this can happen only for
16796 assignments that come from aggregates.
16797 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
16798 in order to alleviate the upward compatibility introduced by AI-318.
16799 (Expand_N_Extended_Return_Statement): Add support for handling the
16800 return object as a build-in-place result.
16801 (Expand_Non_Function_Return): Implement simple return statements nested
16802 within an extended return.
16803 (Enable_New_Return_Processing): Turn on the new processing of return
16805 (Expand_Non_Function_Return): For a return within an extended return,
16806 don't raise Program_Error, because Sem_Ch6 now gives a warning.
16807 (Expand_N_Extended_Return_Statement): Implement AI-318
16808 (Expand_Simple_Function_Return): Ditto.
16809 (Expand_N_If_Statement): Handle new -gnatwt warning

16811 (Expand_N_Assignment): Handle assignment to the Priority attribute of
16812 a protected object.
16813 (Expand_N_Assignment_Statement): Implement -gnatVe/E to control
16814 validity checking of assignments to elementary record components.
16815 (Expand_N_Return_Statement): return Class Wide types on the secondary
16816 stack independantly of their controlled status since with HIE runtimes,
16817 class wide types are not potentially controlled anymore.
16819 * expander.adb (Expand): Add case for new N_Extended_Return_Statement
16822 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Avoid
16823 Expand_Cleanup_Actions in case of N_Extended_Return_Statement, because
16824 it expects a block, procedure, or task. The return statement will get
16825 turned into a block, and Expand_Cleanup_Actions will happen then.

16829 Bob Duff <duff@adacore.com>
16830 Gary Dismukes <dismukes@adacore.com>
16832 * exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
16834 (Expand_Inlined_Call): Tagged types are by-reference types, and
16835 therefore should be replaced by a renaming declaration in the expanded
16836 body, as is done for limited types.
16837 (Expand_Call): If this is a call to a function with dispatching access
16838 result, propagate tag from context.
16839 (Freeze_Subprogram): Enable full ABI compatibility for interfacing with
16841 (Make_Build_In_Place_Call_In_Assignment): New procedure to do
16842 build-in-place when the right-hand side of an assignment is a
16843 build-in-place function call.
16844 (Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
16845 of the explicit dereference of the allocator to the result subtype of
16846 the build-in-place function. This is needed to satisfy type checking
16847 in cases where the caller's return object is created by an allocator for
16848 a class-wide access type and the type named in the allocator is a
16850 (Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
16851 conversion of the reference to the declared object to the result subtype
16852 of the build-in-place function. This is needed to satisfy type checking
16853 in cases where the declared object has a class-wide type. Also, in the
16854 class-wide case, change the type of the object entity to the specific
16855 result subtype of the function, to avoid passing a class-wide object
16856 without explicit initialization to the back end.
16857 (Register_Interface_DT_Entry): Moved outside the body of
16858 Freeze_Subprogram because this routine is now public; it is called from
16859 Check_Dispatching_Overriding to handle late overriding of abstract
16860 interface primitives.
16861 (Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for
16862 adding an implicit access actual on a call to a build-in-place function.
16863 (Expand_Actuals): Test for an actual parameter that is a call to a
16864 build-in-place function and apply
16865 Make_Build_In_Place_Call_In_Anonymous_Context to the call.
16866 (Is_Build_In_Place_Function): New function to determine whether an
16867 entity is a function whose calls should be handled as build-in-place.
16868 (Is_Build_In_Place_Function_Call): New function to determine whether an
16869 expression is a function call that should handled as build-in-place.
16870 (Make_Build_In_Place_Call_In_Allocator): New procedure for handling
16871 calls to build-in-place functions as the initialization of an allocator.
16872 (Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
16873 handling calls to build-in-place functions in contexts that do not
16874 involve init of a separate object (for example, actuals of subprogram
16876 (Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
16877 handling calls to build-in-place functions as the initialization of an
16878 object declaration.

16880 instantiation of Traverse_Body to avoid unreferenced warning.
16881 (Check_Overriding_Inherited_Interfaces): Removed.
16882 (Register_Interface_DT_Entry): Code cleanup.
16883 (Register_Predefined_DT_Entry): Code cleanup.
16884 (Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
16885 inlined statements if within a transient scope.
16886 (Expand_Inlined_Call.Process_Formals): When replacing occurrences of
16887 formal parameters with occurrences of actuals in inlined body, establish
16888 visibility on the proper view of the actual's subtype for the body's
16890 (Freeze_Subprogram): Do nothing if we are compiling under full ABI
16891 compatibility mode and we have an imported CPP subprogram because
16892 for now we assume that imported CPP primitives correspond with
16893 objects whose constructor is in the CPP side (and therefore we
16894 don't need to generate code to register them in the dispatch table).
16895 (Expand_Actuals): Introduce copy of actual, only if it might be a bit-
16896 aligned selected component.
16897 (Add_Call_By_Copy_Node): Add missing code to handle the case in which
16898 the actual of an in-mode parameter is a type conversion.
16899 (Expand_Actuals): If the call does not come from source and the actual
16900 is potentially misaligned, let gigi handle it rather than rejecting the
16901 (Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
16902 Class Wide types as returning by reference independantly of their
16903 controlled status since with HIE runtimes class wide types are not
16904 potentially controlled anymore.

16909 references that are private components of the protected object.

16911 (Update_Prival_Subtypes): Add explicit Process argument to Traverse_Proc
16912 instantiation to deal with warnings.

16919 * exp_dbug.ads, exp_dbug.adb (Get_External_Name): Add missing
16920 initialization of Homonym_Len.
16921 (Fully_Qualify_Name): Remove kludge to eliminate anonymous block
16922 names from fully qualified name. Fixes problem of duplicate
16923 external names differing only in the presence of such a block name.
16925 2006-10-31 Thomas Quinot <quinot@adacore.com>
16926 Pablo Oliveira <oliveira@adacore.com>
16928 * exp_dist.adb (Get_Subprogram_Ids): This function will no more assign
16929 subprogram Ids, even if they are not yet assigned.
16930 (Build_Subprogram_Id): It is now this function that will take care of
16931 calling Assign_Subprogram_Ids if necessary.
16932 (Add_Receiving_Stubs_To_Declarations): Checking the subprograms ids
16933 should be done only once they are assigned.
16934 (Build_From_Any_Function, case of tagged types): Add missing call to
16936 (Corresponding_Stub_Type): New subprogram. Returns the associated stub
16937 type for an RACW type.
16938 (Add_RACW_Features): When processing an RACW declaration for which the
16939 designated type is already frozen, enforce E.2.2(14) rules immediately.
16940 (GARLIC_Support.Build_Subprogram_Receiving_Stubs): Do not perform any
16941 special reordering of controlling formals.
16943 * exp_dist.ads (Corresponding_Stub_Type): New subprogram. Returns the
16944 associated stub type for an RACW type.
16946 2006-10-31 Ed Schonberg <schonberg@adacore.com>
16948 * exp_fixd.adb (Rounded_Result_Set): For multiplication and division of
16949 fixed-point operations in an integer context, i.e. as operands of a
16950 conversion to an integer type, indicate that result must be rounded.
16952 2006-10-31 Robert Dewar <dewar@adacore.com>
16954 * exp_imgv.adb (Expand_Image_Attribute): For Wide_[Wide_]Character
16955 cases, pass the encoding method, since it is now required by the run
16958 * s-valwch.ads, s-valwch.adb (Value_Wide_Wide_Character): Avoid
16959 assumption that Str'First = 1.
16960 (Value_Wide_Character): Takes EM (encoding method) parameter and passes
16961 it on to the Value_Wide_Wide_Character call.
16962 (Value_Wide_Wide_Character): Takes EM (encoding method) parameter and
16963 properly handles a string of the form quote-encoded_wide_char-quote.
16965 * s-wchcnv.adb: Minor reformatting
16967 2006-10-31 Javier Miranda <miranda@adacore.com>
16969 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Add missing
16970 run-time membership test to ensure that the constructed object
16971 implements the target abstract interface.
16973 2006-10-31 Robert Dewar <dewar@adacore.com>
16975 * exp_prag.adb (Expand_Pragma_Common_Object): Use a single
16976 Machine_Attribute pragma internally to implement the user pragma.
16977 Add processing for pragma Interface so that it is now completely
16978 equivalent to pragma Import.
16980 * sem_prag.adb (Analyze_Pragma, case Obsolescent): Extend this pragma
16981 so that it can be applied to all entities, including record components
16982 and enumeration literals.
16983 (Analyze_Pragma, case Priority_Specific_Dispatching): Check whether
16984 priority ranges are correct, verify compatibility against task
16985 dispatching and locking policies, and if everything is correct an entry
16986 is added to the table containing priority specific dispatching entries
16987 for this compilation unit.
16988 (Delay_Config_Pragma_Analyze): Delay processing
16989 Priority_Specific_Dispatching pragmas because when processing the
16990 pragma we need to access run-time data, such as the range of
16991 System.Any_Priority.
16992 (Sig_Flags): Add Pragma_Priority_Specific_Dispatching.
16993 Allow pragma Unreferenced as a context item
16994 Add pragma Preelaborable_Initialization
16995 (Analyze_Pragma, case Interface): Interface is extended so that it is
16996 now syntactically and semantically equivalent to Import.
16997 (Analyze_Pragma, case Compile_Time_Warning): Fix error of blowups on
16998 insertion characters.
16999 Add handling for Pragma_Wide_Character_Encoding
17000 (Process_Restrictions_Restriction_Warnings): Ensure that a warning
17001 never supercedes a real restriction, and that a real restriction
17002 always supercedes a warning.
17003 (Analyze_Pragma, case Assert): Set Low_Bound_Known if assert is of

17007 Ed Schonberg <schonberg@adacore.com>
17008 Robert Dewar <dewar@adacore.com>
17010 * exp_ch7.adb (Build_Array_Deep_Procs, Build_Record_Deep_Procs,
17011 Make_Deep_Record_Body): Rename Is_Return_By_Reference_Type to be
17012 Is_Inherently_Limited_Type, because return-by-reference has no meaning
17014 (Find_Node_To_Be_Wrapped): Use new method of determining the result
17015 type of the function containing a return statement, because the
17016 Return_Type field was removed. We now use the Return_Applies_To field.
17018 * exp_util.ads, exp_util.adb: Use new subtype N_Membership_Test
17019 (Build_Task_Image_Decl): If procedure is not called from an
17020 initialization procedure, indicate that function that builds task name
17021 uses the sec. stack. Otherwise the enclosing initialization procedure
17022 will carry the indication.
17023 (Insert_Actions): Remove N_Return_Object_Declaration. We now use
17024 N_Object_Declaration instead.
17025 (Kill_Dead_Code): New interface to implement -gnatwt warning for
17026 conditional dead code killed, and change implementation accordingly.
17027 (Insert_Actions): Add N_Return_Object_Declaration case.
17028 Correct comment to mention N_Extension_Aggregate node.
17029 (Set_Current_Value_Condition): Call Safe_To_Capture_Value to avoid bad
17030 attempts to save information for global variables which cannot be
17032 (Get_Current_Value_Condition): Handle conditions the other way round
17033 (constant on left). Also handle right operand of AND and AND THEN
17034 (Set_Current_Value_Condition): Corresponding changes
17035 (Append_Freeze_Action): Remove unnecessary initialization of Fnode.
17036 (Get_Current_Value_Condition): Handle simple boolean operands
17037 (Get_Current_Value_Condition): Handle left operand of AND or AND THEN
17038 (Get_Current_Value_Condition): If the variable reference is within an
17039 if-statement, does not appear in the list of then_statments, and does
17040 not come from source, treat it as being at unknown location.
17041 (Get_Current_Value_Condition): Enhance to allow while statements to be
17042 processed as well as if statements.
17043 (New_Class_Wide_Subtype): The entity for a class-wide subtype does not
17045 (OK_To_Do_Constant_Replacement): Allow constant replacement within body
17046 of loop. This is safe now that we fixed Kill_Current_Values.
17047 (OK_To_Do_Constant_Replacement): Check whether current scope is
17048 Standard, before examining outer scopes.
17050 2006-10-31 Vincent Celier <celier@adacore.com>
17052 * krunch.ads, krunch.adb (Krunch): New Boolean parameter VMS_On_Target.
17053 When True, apply VMS treatment to children of packages A, G, I and S.
17056 * fname-uf.adb (Get_File_Name): Call Krunch with OpenVMS_On_Target
17058 2006-10-31 Robert Dewar <dewar@adacore.com>
17059 Ed Schonberg <schonberg@adacore.com>

17062 (Warn_Overlay): Supply missing continuation marks in error msgs
17063 (Freeze_Entity): Add check for Preelaborable_Initialization
17065 * g-comlin.adb: Add Warnings (Off) to prevent new warning
17067 * g-expect.adb: Add Warnings (Off) to prevent new warning
17069 * lib-xref.adb: Add handling of Last_Assignment field
17070 (Generate_Reference): Centralize handling of pragma Obsolescent here
17071 (Generate_Reference): Accept an implicit reference generated for a
17072 default in an instance.
17073 (Generate_Reference): Accept a reference for a node that is not in the
17074 main unit, if it is the generic body corresponding to an subprogram
17077 * xref_lib.adb: Add pragma Warnings (Off) to avoid new warnings
17079 * sem_warn.ads, sem_warn.adb (Set_Warning_Switch): Add processing for
17081 (Warn_On_Useless_Assignment): Suppress warning if enclosing inner
17083 (Output_Obsolescent_Entity_Warnings): Rewrite to avoid any messages on
17084 use clauses, to avoid messages on packages used to qualify, and also
17085 to avoid messages from obsolescent units.
17086 (Warn_On_Useless_Assignments): Don't generate messages for imported
17087 and exported variables.
17088 (Warn_On_Useless_Assignments): New procedure
17089 (Output_Obsolescent_Entity_Warnings): New procedure
17090 (Check_Code_Statement): New procedure
17092 * einfo.ads, einfo.adb (Has_Static_Discriminants): New flag

17094 (Last_Assignment): New field for useless assignment warning
17096 2006-10-31 Olivier Hainque <hainque@adacore.com>
17098 * g-alleve.adb (lvx, stvx): Ceil-Round the Effective Address to the
17099 closest multiple of VECTOR_ALIGNMENT and not the closest multiple of 16.
17101 2006-10-31 Bob Duff <duff@adacore.com>
17102 Robert Dewar <dewar@adacore.com>
17103 Ed Schonberg <schonberg@adacore.com>
17105 * g-awk.adb (Default_Session, Current_Session): Compile this file in
17106 Ada 95 mode, because it violates the new rules for AI-318.
17108 * g-awk.ads: Use overloaded subprograms in every case where we used to
17109 have a default of Current_Session. This makes the code closer to be
17110 correct for both Ada 95 and 2005.
17112 * g-moreex.adb (Occurrence): Turn off warnings for illegal-in-Ada-2005
17113 code, relying on the fact that the compiler generates a warning
17114 instead of an error in -gnatg mode.
17116 * lib-xref.ads (Xref_Entity_Letters): Add entry for new
17117 E_Return_Statement entity kind.
17118 Add an entry for E_Incomplete_Subtype in Xref_Entity_Letters.
17120 * par.adb (P_Interface_Type_Definition): Addition of one formal to
17121 report an error if the reserved word abstract has been previously found.
17122 (SS_End_Type): Add E_Return for new extended_return_statement syntax.
17124 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve message for
17125 parenthesized range attribute usage
17126 (P_Expression_No_Right_Paren): Add missing comment about error recovery.
17128 * par-ch6.adb (P_Return_Object_Declaration): AI-318: Allow "constant"
17129 in the syntax for extended_return_statement. This is not in the latest
17130 RM, but the ARG is expected to issue an AI allowing this.
17131 (P_Return_Subtype_Indication,P_Return_Subtype_Indication): Remove
17132 N_Return_Object_Declaration. We now use N_Object_Declaration instead.
17133 (P_Return_Object_Declaration, P_Return_Subtype_Indication,
17134 P_Return_Statement): Parse the new syntax for extended_return_statement.
17136 * par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
17137 Output_End_Missing): Add error-recovery code for the new
17138 extended_return_statement syntax; that is, the new E_Return entry on
17141 * s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
17142 limited to nonlimited, because otherwise we violate the new Ada 2005
17143 rules about returning limited types in function Create_AST_Handler in
17146 * sem.adb (Analyze): Add cases for new node kinds
17147 N_Extended_Return_Statement and N_Return_Object_Declaration.
17149 * sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
17150 type is in the same category as type of context before applying check,
17151 to prevent anomalies in instantiations.
17152 (Resolve_Aggregate): Remove test for limited components in aggregates.
17153 It's unnecessary in Ada 95, because if it has limited components, then
17154 it must be limited. It's wrong in Ada 2005, because limited aggregates
17156 (Resolve_Record_Aggregate): Move check for limited types later, because
17157 OK_For_Limited_Init requires its argument to have been resolved.
17158 (Get_Value): When copying the component default expression for a
17159 defaulted association in an aggregate, use the sloc of the aggregate
17160 and not that of the original expression, to prevent spurious
17161 elaboration errors, when the expression includes function calls.
17162 (Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
17163 were missing. We also didn't handle qualified expressions. Now also
17164 allow function calls. Use new common routine OK_For_Limited_Init.
17165 (Resolve_Extension_Aggregate): Minor fix to bad error message (started
17166 with space can upper case letter).
17168 * sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
17169 Has_Static_Discriminants flag
17170 (Record_Type_Declaration): Diagnose an attempt to declare an interface
17171 type with discriminants.
17172 (Process_Range_Expr_In_Decl): Do validity checks on range
17173 (Build_Discriminant_Constraints): Use updated form of
17174 Denotes_Discriminant.
17175 (Process_Subtype): If the subtype is a private subtype whose full view
17176 is a concurrent subtype, introduce an itype reference to prevent scope
17178 (Build_Derived_Record_Type, Collect_Interface_Primitives,
17179 Record_Type_Declaration): The functionality of the subprograms
17180 Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
17181 is now performed by a single routine.
17182 (Build_Derived_Record_Type): If the type definition includes an explicit
17183 indication of limitedness, then the type must be marked as limited here
17184 to ensure that any access discriminants will not be treated as having
17185 a local anonymous access type.
17186 (Check_Abstract_Overriding): Issue a detailed error message when an
17187 abstract subprogram was not overridden due to incorrect mode of its
17189 (Analyze_Private_Extension_Declaration): Add support for the analysis of
17190 synchronized private extension declarations. Verify that the ancestor is
17191 a limited or synchronized interface or in the generic case, the ancestor
17192 is a tagged limited type or synchronized interface and all progenitors
17193 are either limited or synchronized interfaces.
17194 Derived_Type_Declaration): Check for presence of private extension when
17195 dealing with synchronized formal derived types.
17196 Process_Full_View): Enchance the check done on the usage of "limited" by
17197 testing whether the private view is synchronized.
17198 Verify that a synchronized private view is completed by a protected or
17200 (OK_For_Limited_Init_In_05): New function.
17201 (Analyze_Object_Declaration): Move check for limited types later,
17202 because OK_For_Limited_Init requires its argument to have been resolved.
17203 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17204 in order to alleviate the upward compatibility introduced by AI-318.
17205 (Constrain_Corresponding_Record): If the constraint is for a component
17206 subtype, mark the itype as frozen, to avoid out-of-scope references to
17207 discriminants in the back-end.
17208 (Collect_Implemented_Interfaces): Protect the recursive algorithm of
17209 this subprogram against wrong sources.
17210 (Get_Discr_Value, Is_Discriminant): Handle properly references to a
17211 discriminant of limited type completed with a protected type, when the
17212 discriminant is used to constrain a private component of the type, and
17213 expansion is disabled.
17214 (Find_Type_Of_Object): Do not treat a return subtype that is an
17215 anonymous subtype as a local_anonymous_type, because its accessibility
17216 level is the return type of the enclosing function.
17217 (Check_Initialization): In -gnatg mode, turn the error "cannot
17218 initialize entities of limited type" into a warning.
17219 (OK_For_Limited_Init): Return true for generated nodes, since it
17220 sometimes violates the legality rules.
17221 (Make_Incomplete_Declaration): If the type for which an incomplete
17222 declaration is created happens to be the currently visible entity,
17223 preserve the homonym chain when removing it from visibility.
17224 (Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
17225 inherited subprograms.
17226 (Access_Definition): If this is an access to function that is the return
17227 type of an access_to_function definition, context is a type declaration
17228 and the scope of the anonymous type is the current one.
17229 (Analyze_Subtype_Declaration): Add the defining identifier of a regular
17230 incomplete subtype to the set of private dependents of the original
17232 (Constrain_Discriminated_Type): Emit an error message whenever an
17233 incomplete subtype is being constrained.
17234 (Process_Incomplete_Dependents): Transform an incomplete subtype into a
17235 corresponding subtype of the full view of the original incomplete type.
17236 (Check_Incomplete): Properly detect invalid usage of incomplete types
17239 2006-10-31 Hristian Kirtchev <kirtchev@adacore.com>
17241 * g-catiio.ads, g-catiio.adb (Value): New function.

17250 Robert Dewar <dewar@adacore.com>
17252 * gnatcmd.adb (Process_Link): Use Osint.Executable_Name instead of
17253 handling executable extension manually and duplicating code.
17255 * make.adb: Implement new -S switch
17256 (Gnatmake): Use new function Osint.Executable_Name instead
17257 of handling executable extension manually.
17259 * prj-util.adb (Executable_Of): Make sure that if an Executable_Suffix
17260 is specified, the executable name ends with this suffix.
17261 Take advantage of Osint.Executable_Name instead of duplicating code.
17263 * switch-m.adb: Recognize new gnatmake -S switch
17265 * targparm.ads, targparm.adb (Executable_Extension_On_Target): New
17267 (Get_Target_Parameters): Set Executable_Extension_On_Target if
17270 * makeusg.adb: Add line for gnatmake -S switch
17272 2006-10-31 Vincent Celier <celier@adacore.com>
17274 * gnatlink.adb (Gnatlink): If gcc is not called with -shared-libgcc,
17275 call it with -static-libgcc, as there are some platforms, such as
17276 Darwin, where one of these two switches is compulsory to link.
17278 2006-10-31 Vincent Celier <celier@adacore.com>
17280 * gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
17281 instead of ADA_PROJECT_PATH, for the project path.
17282 (Gnatls): When displaying the project path directories, use host dir
17285 * prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
17286 names in the project path, as absolute paths may correspond to
17287 multi-valued VMS logical names.
17289 2006-10-31 Vincent Celier <celier@adacore.com>
17291 * g-os_lib.ads, g-os_lib.adb (Locate_Exec_On_Path): Always return an
17292 absolute path name.
17293 (Locate_Regular_File): Ditto
17294 (Change_Dir): Remove, no longer used
17295 (Normalize_Pathname): Do not use Change_Dir to get the drive letter
17296 on Windows. Get it calling Get_Current_Dir.
17297 (OpenVMS): Remove imported boolean, no longer needed.
17298 (Normalize_Pathname)[VMS]: Do not resolve directory names.
17299 (Pid_To_Integer): New function to convert a Process_Id to Integer
17301 2006-10-31 Thomas Quinot <quinot@adacore.com>
17303 * g-socket.ads, g-socket.adb (Close_Selector): Once the signalling
17304 sockets are closed, reset the R_Sig_Socket and W_Sig_Socket components
17306 (Selector_Type): Add default value of No_Socket for R_Sig_Socket and
17309 2006-10-31 Robert Dewar <dewar@adacore.com>
17311 * g-speche.ads, g-speche.adb: Add special case to recognize misspelling
17312 initial letter o as a zero.

17318 2006-10-31 Robert Dewar <dewar@adacore.com>
17320 * layout.adb (Layout_Record_Type): Deal with non-static subtypes of
17322 (Layout_Variant_Record): Retrieve the discriminants from the entity
17323 rather than from the type definition, because in the case of a full
17324 type for a private type we need to take the discriminants from the
17326 (Layout_Component_List): When applying the Max operator to variants with
17327 a nonstatic size, check whether either operand is static and scale that
17328 operand from bits to storage units before applying Max.
17329 (Layout_Type): In VMS, if a C-convention access type has no explicit
17330 size clause (and does not inherit one in the case of a derived type),
17331 then the size is reset to 32 from 64.
17333 2006-10-31 Vincent Celier <celier@adacore.com>
17335 * lib-load.adb (Load_Unit): Skip the test for a unit not found when
17336 its file has already been loaded, according to the unit being loaded,
17337 not to the current value of Multiple_Unit_Index.
17339 2006-10-31 Thomas Quinot <quinot@adacore.com>
17340 Eric Botcazou <ebotcazou@adacore.com>
17341 Arnaud Charlet <charlet@adacore.com>
17343 * Makefile.in: Set EH mechanism to ZCX for FreeBSD.
17344 (NO_REORDER_ADAFLAGS): New var defined to -fno-toplevel-reorder if
17346 (a-except.o): Pass it to the compiler.
17347 (gnatlib-shared-vms): Removed -nostartfiles switch in link step.
17348 (LIBGNAT_TARGET_PAIRS for Windows): Avoid the use of the specific
17349 a-calend-mingw.adb version.
17351 * Makefile.rtl: Added s-dsaser.
17352 Add object entries for Ada.Calendar.[Arithmetic/Formatting/Time_Zones]
17353 (GNATRTL_TASKING_OBJS): Add Ada.Dispatching and
17354 Ada.Dispatching.Round_Robin.
17355 Added new unit Ada.Containers.Restricted_Bounded_Doubly_Linked_Lists
17357 * Make-lang.in: Remove all references to gt-ada-decl.h.
17358 Add concatenation (s-strops/s-sopco3/s-sopco4/s-sopco5) to compiler

17367 * mlib-utl.adb (Initialized): Remove, no longer used
17368 (Initialize): Remove, no longer used
17369 (Ar): If Ar_Exec is null, get the location of the archive builder and,
17370 if there is one, the archive indexer. Fail if the archive builder cannot

17375 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17377 * sem_ch10.ads, sem_ch10.adb (Check_Redundant_Withs,
17378 Process_Body_Clauses): If the context of a body includes a use clause
17379 for P.Q then a with_clause for P in the same body is not redundant,
17380 even if the spec also has a with_clause on P.
17381 Add missing continuation mark to error msg
17382 (Build_Limited_Views): A limited view of a type is tagged if its
17383 declaration includes a record extension.
17384 (Analyze_Proper_Body): Set Corresponding_Stub field in N_Subunit
17385 node, even if the subunit has errors. This avoids malfunction by
17386 Lib.Check_Same_Extended_Unit in the presence of syntax errors.
17387 (Analyze_Compilation_Unit): Add circuit to make sure we get proper
17388 generation of obsolescent messages for with statements (cannot do
17389 this too early, or we cannot implement avoiding the messages in the
17390 case of obsolescent units withing obsolescent units).
17391 (Install_Siblings): If the with_clause is on a remote descendant of
17392 an ancestor of the current compilation unit, find whether there is
17393 a sibling child unit that is immediately visible.
17394 (Remove_Private_With_Clauses): New procedure, invoked after completing
17395 the analysis of the private part of a nested package, to remove from
17396 visibility the private with_clauses of the enclosing package
17398 (Analyze_With_Clause): Remove Check_Obsolescent call, this checking is
17399 now centralized in Generate_Reference.
17400 (Install_Limited_Context_Clauses): Remove superfluous error
17401 message associated with unlimited view visible through use
17402 and renamings. In addition, at the point in which the error
17403 is reported, we add the backslash to the text of the error
17404 to ensure that it is reported as a single error message.
17405 Use new // insertion for some continuation messages
17406 (Expand_Limited_With_Clause): Use copy of name rather than name itself,
17407 to create implicit with_clause for parent unit mentioned in original
17408 limited_with_clause.
17409 (Install_Limited_With_Unit): Set entity of parent identifiers if the
17410 unit is a child unit. For ASIS queries.
17411 (Analyze_Subunit): If the subunit appears within a child unit, make all
17412 ancestor child units directly visible again.

17427 a formal object declaration with an access definition or a subtype mark
17428 with a null exclusion.
17429 (P_Generic_Association): Handle association with box, and others_choice
17430 with box, to support Ada 2005 partially parametrized formal packages.

17439 private extensions.
17440 (P_Type_Declaration): Add the new actual Abstract_Present to every call
17441 to P_Interface_Type_Definition.
17442 (P_Interface_Type_Definition): Addition of one formal to report an error
17443 if the reserved word abstract has been previously found.
17444 (P_Identifier_Declarations): Update grammar rules. Handle parsing of an
17445 object renaming declaration with an access definition or subtype mark
17446 with a possible null exclusion.

17473 of sources, even if it is not the first time, as it is for another
17475 (Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
17476 dot, instead of replacing only the first '_'.
17478 * prj-part.adb (Parse): Convert project file path to canonical form
17480 * prj-proc.adb (Recursive_Process): Make sure that, when a project is
17481 extended, the project id of the project extending it is recorded in its
17482 data, even when it has already been processed as an imported project.
17484 2006-10-31 Robert Dewar <dewar@adacore.com>

17490 Robert Dewar <dewar@adacore.com>
17492 * restrict.ads, restrict.adb (Restriction_Active): Now returns False if
17493 only a restriction warning is active for the given restriction. This is
17494 desirable because we do not want to modify code in the case where only
17496 (Set_Profile_Restrictions): Make sure that a Profile_Warnings never
17497 causes overriding of real restrictions.
17498 Take advantage of new No_Restrictions constant.
17500 * raise.h: (__gnat_set_globals): Change profile.
17502 2006-10-31 Arnaud Charlet <charlet@adacore.com>
17504 * rtsfind.adb: Remove s-polint from comment as it exists no more.
17507 Move entity RE_Get_Active_Partition_Id to package System.DSA_Services.

17527 * sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
17528 properly an attempt to apply Unchecked_Access to a protected operation.
17529 (OK_Self_Reference): New subprogram to check the legality of an access
17530 attribute whose prefix is the type of an enclosing aggregate.
17531 Generalizes previous mechanism to handle attribute references nested
17532 arbitrarily deep within the aggregate.
17533 (Analyze_Access_Attribute): An access attribute whose prefix is a type
17534 can appear in an aggregate if this is a default-initialized aggregate
17535 for a self-referential type.
17536 (Resolve_Attribute, case Access): Ditto.
17537 Add support for new implementation defined attribute Stub_Type.
17538 (Eval_Attribute, case Attribute_Stub_Type): New case.
17539 (Analyze_Attribute, case Attribute_Stub_Type): New case.
17540 (Stream_Attribute_Available): Implement using new subprogram from
17541 sem_cat, Has_Stream_Attribute_Definition, instead of incorrect
17542 Has_Specified_Stream_Attribute flag.
17543 Disallow Storage_Size and Storage_Pool for access to subprogram
17544 (Resolve_Attribute, case 'Access et al): Take into account anonymous
17545 access types of return subtypes in extended return statements. Remove
17546 accessibility checks on anonymous access types when Unchecked_Access is
17548 (Analyze_Attribute): Add support for the use of 'Class to convert
17549 a class-wide interface to a tagged type.
17550 Add support for the attribute Priority.
17551 (Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
17552 whether the designated type is discriminated with a constrained partial
17553 view and require static matching in that case.
17554 Add local variable Des_Btyp. The Designated_Type
17555 of an access to incomplete subtype is either its non-limited view if
17556 coming from a limited with or its etype if regular incomplete subtype.
17558 * sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
17559 Fix predicate to identify and allow cases of (expander-generated)
17560 references to tag of designated object of a RACW.
17561 (Validate_Static_Object_Name): In Ada 2005, a formal object is
17562 non-static, and therefore cannot appear as a primary in a preelaborable
17564 (Has_Stream_Attribute_Definition): New subprogram, abstracted from
17565 Has_Read_Write_Attributes.
17566 (Has_Read_Write_Attributes): Reimplement in termes of
17567 Has_Stream_Attribute_Definition.
17568 (Missing_Read_Write_Attributes): When checking component types in a
17569 record, unconditionally call Missing_Read_Write_Attributes recursively
17570 (remove guard checking for Is_Record_Type / Is_Access_Type).
17572 2006-10-31 Robert Dewar <dewar@adacore.com>
17574 * sem_ch11.adb (Analyze_Handled_Statements): Move final test for
17575 useless assignments here and conditionalize it on absence of exception

17578 detection code, for new handling of formal packages.
17580 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17581 Hristian Kirtchev <kirtchev@adacore.com>
17583 * sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
17584 that has been constant-folded, preserve information of original tree,
17586 (Analyze_Formal_Derived_Type): Set the limited present flag of the newly
17587 generated private extension declaration if the formal derived type is
17588 synchronized. Carry synchronized present over to the generated private
17590 (Validate_Derived_Type_Instance): Ensure that the actual of a
17591 synchronized formal derived type is a synchronized tagged type.
17592 (Instantiate_Formal_Package): When creating the instantiation used to
17593 validate the actual package of a formal declared without a box, check
17594 whether the formal itself depends on a prior actual.
17595 (Instantiate_Formal_Subprogram): Create new entities for the defining
17596 identifiers of the formals in the renaming declaration, for ASIS use.
17597 (Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
17598 a renaming declaration or a subtype declaration for an actual in an
17599 instance, capture location information of declaration in generic, for
17601 (Instantiate_Formal_Package): Add comments on needed additional tests.
17602 AI-317 (partial parametrization) is fully implemented.
17603 (Validate_Private_Type_Instance): Add check for actual which
17604 must have preelaborable initialization
17605 Use new // insertion for some continuation messages
17606 (Analyze_Formal_Object_Declaration): Change usage of Expression to
17607 Default_Expression. Add type retrieval when the declaration has an
17608 access definition. Update premature usage of incomplete type check.
17609 (Check_Access_Definition): New subsidiary routine. Check whether the
17610 current compilation version is Ada 05 and the supplied node has an
17612 (Instantiate object): Alphabetize local variables. Handle the creation
17613 of new renaming declarations with respect to the kind of definition
17614 used - either an access definition or a subtype mark. Guard against
17615 unnecessary error message in the context of anonymous access types after
17616 they have been resolved. Add check for required null exclusion in a
17617 formal object declaration.
17618 (Switch_View): A private subtype of a non-private type needs to be
17619 switched (the base type can have been switched without its private
17620 dependents because of the last branch of Check_Private_View.
17621 (Check_Private_View): Do not recompute Base_Type (T), instead use cached
17623 (Instantiate_Type): Emit an error message whenever a class-wide type of
17624 a tagged incomplete type is used as a generic actual.
17625 (Find_Actual_Type): Extend routine to handle a component type in a child
17626 unit that is imported from a formal package in a parent.
17627 (Validate_Derived_Type_Instance): Check that analyzed formal and actual
17628 agree on constrainedness, rather than checking against ultimate ancestor
17629 (Instantiate_Subprogram_Body): Create a cross-reference link to the
17630 generic body, for navigation purposes.
17632 2006-10-31 Robert Dewar <dewar@adacore.com>
17633 Thomas Quinot <quinot@adacore.com>
17635 * sem_ch13.adb: Storage pool cannot be given for access to subprogram
17637 (New_Stream_Subprogram): When processing an attribute definition clause
17638 for a stream-oriented subprogram, record an entity node occurring at
17639 the point of clause to use for checking the visibility of the clause,
17640 as defined by 8.3(23) as amended by AI-195.
17641 (New_Stream_Subprogram): New procedure, factoring behaviour from both
17642 New_Stream_Function and New_Stream_Procedure.
17643 (New_Stream_Function, New_Stream_Procedure): Removed.
17644 (Analyze_Attribute_Definition_Clause, case Address): Check new
17645 Alignment_Check check

17648 Javier Miranda <miranda@adacore.com>
17649 Robert Dewar <dewar@adacore.com>
17651 * sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
17652 generate the same errors compiling under -gnatc.
17653 (Try_Object_Operation): If no candidate interpretation succeeds, but
17654 there is at least one primitive operation with the right name, report
17655 error in call rather than on a malformed selected component.
17656 (Analyze_Selected_Component): If the prefix is an incomplete type from
17657 a limited view, and the full view is available, use the full view to
17658 determine whether this is a prefixed call to a primitive operation.
17659 (Operator_Check): Verify that a candidate interpretation is a binary
17660 operation before checking the type of its second formal.
17661 (Analyze_Call): Add additional warnings for function call contexts not
17663 (Analyze_Allocator): Move the check for "initialization not allowed for
17664 limited types" after analyzing the expression. This is necessary,
17665 because OK_For_Limited_Init looks at the structure of the expression.
17666 Before analysis, we don't necessarily know what sort of expression it
17667 is. For example, we don't know whether F(X) is a function call or an
17668 indexed component; the former is legal in Ada 2005; the latter is not.
17669 (Analyze_Allocator): Correct code for AI-287 -- extension aggregates
17670 were missing. We also didn't handle qualified expressions. Now also
17671 allow function calls. Use new common routine OK_For_Limited_Init.
17672 (Analyze_Type_Conversion): Do not perform some legality checks in an
17673 instance, because the error message will be redundant or spurious.
17674 (Analyze_Overloaded_Selected_Component): Do not do style check when
17675 setting an entity, since we do not know it is the right entity yet.
17676 (Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
17677 (Analyze_Overloaded_Selected_Component): Same change
17678 (Analyze_Selected_Component): Remove unnecessary prefix type retrieval
17679 since regular incomplete subtypes are transformed into corresponding
17680 subtypes of their full views.
17681 (Complete_Object_Operation): Treat name of transformed subprogram call
17682 as coming from source, for browsing purposes.
17683 (Try_Primitive_Operation): If formal is an access parameter, compare
17684 with base type of object to determine whether it is a primitive
17686 (Operator_Check): If no interpretation of the operator matches, check
17687 whether a use clause on any candidate might make the operation legal.
17688 (Try_Class_Wide_Operation): Check whether the first parameter is an
17689 access type whose designated type is class-wide.

17692 Ed Schonberg <schonberg@adacore.com>
17693 Gary Dismukes <dismukes@adacore.com>

17696 warn on infinite loops.
17697 Add \\ to some continuation messages
17698 (Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
17699 (Process_Bounds): If the bounds are integer literals that result from
17700 constant-folding, and they carry a user-defined type, preserve that type
17701 rather than treating this as an integer range.
17702 (Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
17703 (Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
17704 (Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
17705 left hand side of assignment.
17706 (Analyze_Assignment): Add suport to manage assigments to the attribute
17707 priority of a protected object.
17708 (Check_Possible_Current_Value_Condition): Allow fully qualified names
17709 not just identifiers.
17710 (Check_Possible_Current_Value_Condition): Acquire left operand of AND
17711 or AND THEN for possible tracking.
17712 (Analyze_Iteration_Scheme): Check for setting Current_Value for the
17713 case of while loops so we can track values in the loop body.
17715 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17716 Hristian Kirtchev <kirtchev@adacore.com>
17717 Bob Duff <duff@adacore.com>
17719 * sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
17720 procedure cannot be a protected operation (it is a basic_declaration,
17721 not a subprogram_declaration).
17722 (Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
17723 Subp. Add logic for entry processing.
17724 (Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
17725 Determine whether an entry or subprogram of a protected or task type
17726 override an inherited primitive of an implemented interface.
17727 (New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
17728 Update the actual used in calls to Check_Overriding_Indicator.
17729 (Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
17730 generate the proper reference to the parent unit, for cross-reference.
17731 (Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
17733 Add -gnatd.l --Use Ada 95 semantics for limited function returns,
17734 (Add_Extra_Formal): Revise procedure to allow passing in associated
17735 entity, scope, and name suffix, and handle setting of the new
17736 Extra_Formals field.
17737 (Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
17738 pass new parameters. Add support for adding the new extra access formal
17739 for functions whose calls are treated as build-in-place.
17740 (Analyze_A_Return_Statement): Correct casing in error message.
17741 Move Pop_Scope to after Analyze_Function_Return, because an extended
17742 return statement really is a full-fledged scope. Otherwise, visibility
17743 doesn't work right. Correct use of "\" for continuation messages.
17744 (Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
17745 evilly trying to call Analyze_Object_Declaration directly. Otherwise,
17746 the node doesn't get properly marked as analyzed.
17747 (Analyze_Subprogram_Body): If subprogram is a function that returns
17748 an anonymous access type that denotes a task, build a Master Entity
17750 (Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
17751 proper usage of null exclusion in a result definition.
17752 (Process_Formals): Code cleanup and new error message.
17753 (Process_Formals): Detect incorrect application of null exclusion to
17755 (Conforming_Types): Handle conformance between [sub]types and itypes
17756 generated for entities that have null exclusions applied to them.
17757 (Maybe_Primitive_Operation): Add an additional type retrieval when the
17758 base type is an access subtype. This case arrises with null exclusions.
17759 (New_Overloaded_Entity): Do not remove the overriden entity from the
17760 homonym chain if it corresponds with an abstract interface primitive.
17761 (Process_Formals): Replace membership test agains Incomplete_Kind with a
17762 call to the synthesized predicate Is_Incomplete_Type.
17763 (Analyze_Subprogram_Body): Check wrong placement of abstract interface
17765 (Analyze_Subprogram_Declaration): Check that abstract interface
17766 primitives are abstract or null.
17767 (Analyze_Subprogram_Specification): Remove previous check for abstract
17768 interfaces because it was not complete.
17769 (Has_Interface_Formals): Removed.
17771 2006-10-31 Ed Schonberg <schonberg@adacore.com>
17772 Javier Miranda <miranda@adacore.com>
17774 * sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
17775 of Analyze_Package_Body, to create Itype references for anonymous
17776 access types created in the package declaration, whose designated types
17777 may have only a limited view.
17778 (Analyze_Package_Specification): For the private part of a nested
17779 package, install private_with_clauses of enclosing compilation unit if
17780 we are in its visible part.
17781 (Declare_Inherited_Private_Subprograms): Complete barrier
17782 to ensure that the primitive operation has an alias to some parent
17783 primitive. This is now required because, after the changes done for the
17784 implementation of abstract interfaces, the contents of the list of
17785 primitives has entities whose alias attribute references entities of
17786 such list of primitives.
17787 (Analyze_Package_Specification): Simplify code that handles parent units
17788 of instances and formal packages.
17789 (Uninstall_Declarations): Check the convention consistency among
17790 primitive overriding operations of a tagged record type.

17797 * sem_ch8.adb: Minor error msg rewording
17798 (Undefined): When checking for misspellings, invert arguments (to get
17799 expected and found set right)
17800 (Analyze_Subprogram_Renaming): Propagate Is_Pure, Is_Preelaborated
17801 (Analyze_Generic_Renaming): Same fix
17802 (Use_One_Package): Do not take into account the internal entities of
17803 abstract interfaces during the analysis of entities that are marked
17804 as potentially use-visible.
17805 (Find_Type): Handle the case of an attribute reference for
17806 implementation defined attribute Stub_Type (simply let the analysis of
17807 the attribute reference rewrite it).
17808 (Use_One_Type, End_Use_Type): Reject a reference to a limited view of a
17809 type that appears in a Use_Type clause.
17810 (Analyze_Object_Renaming): Add support for renaming of the Priority
17812 (Find_Type): In Ada 2005, a task type can be used within its own body,
17813 when it appears in an access definition.
17814 (Analyze_Object_Renaming): Remove warning on null_exclusion.
17815 (Analyze_Object_Renaming): Introduce checks for required null exclusion
17816 in a formal object declaration or in a subtype declaration.
17817 (Analyze_Subprogram_Renaming): Add call to Check_Null_Exclusion.
17818 (Check_Null_Exclusion): New local routine to
17819 Analyze_Subprogram_Renaming. Check whether the formals and return
17820 profile of a renamed subprogram have required null exclusions when
17821 their counterparts of the renaming already impose them.
17822 (In_Generic_Scope): New local routine to Analyze_Object_Renaming.
17823 Determine whether an entity is inside a generic scope.
17824 (In_Open_Scope): First pass of documentation update.
17825 (Find_Expanded_Name): Add support for shadow entities associated with
17826 limited withed packages. This is required to handle nested packages.
17827 (Analyze_Package_Renaming): Remove the restriction imposed by AI-217

18178 This is a significant redesign primarily for the sake of automatic
18179 timer task termination but also to fix a design flaw.

19030 other basic tools. The full version that includes the Ada 2005 stuff

19283 after hyphen (small aesthetic change useful for a range of numbers
19285 Suppress range checks for a couple of assignments which otherwise
19286 cause validity checks with validity checking turned on.

19289 Improvement in error message for object.
19290 (Rep_Item_Too_Late): Remove '!' in warning message.

19293 Eric Botcazou <ebotcazou@adacore.com>
19295 * err_vars.ads: Suppress range checks for a couple of assignments
19296 which otherwise cause validity checks with validity checking turned on.

19306 implied by '?' in error messages.
19308 * gnat1drv.adb: (Bad_Body): Remove '!' in warning message.
19309 (Gnat1drv): Use a goto to end of main subprogram instead of
19310 Exit_Program (E_Success) so that finalization can occur normally.

19328 Thomas Quinot <quinot@adacore.com>
19330 * checks.adb (Build_Discriminant_Checks): If the expression being
19331 checks is an aggregate retrieve the values of its discriminants to
19332 generate the check, rather than creating a temporary and a reference

19335 (Install_Null_Excluding_Check): Ditto
19336 (Selected_Length_Checks): Build actual subtype for the original Ck_Node,

19348 (Scan_Make_Switches): When failing with an illegal switch, output an
19349 error message with the full switch.
19350 Eliminate numeric switches for binder/gnatmake
19352 * switch.ads, switch.adb (Bad_Switch): New procedure
19354 * switch-b.adb (Scan_Binder_Switches): Do not accept combined switches.
19355 Remove 0-9 as debug flag character possibilities
19356 -d is now controlling the primary stack size when its value is a
19357 positive. Also add checks against invalid values, and support for kb,
19358 mb. Ditto for -D switch.
19360 2006-02-13 Robert Dewar <dewar@adacore.com>
19361 Serguei Rybin <rybin@adacore.com>
19363 * opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
19364 save/restore routines.
19365 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19366 were not always properly handled previously.
19367 Since we are changing the tree format anyway, also get rid of the
19368 junk obsolete Immediate_Errors flag.
19369 (Tree_Read): Change the way of reading Tree_Version_String - now we
19370 read the version string from the tree even if its length is not the
19371 same as the length of the version string computed from Gnatvsn.
19372 (Search_Directory_Present): New Boolean flag for the compiler.
19373 Define Tree_Version_String as a dynamic string.
19374 (Default_Stack_Size): new variable, used to handle switch -d.
19377 For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
19378 only for main unit.
19379 Add pragma Ada_2005 (synonym for Ada_05)
19380 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
19381 were not always properly handled previously.

19387 Robert Dewar <dewar@adacore.com>
19388 Ed Schonberg <schonberg@adacore.com>
19390 * einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend
19391 against errors in the source program: a private types for which the
19392 corresponding full type declaration is missing and pragma CPP_Virtual
19394 (Is_Unchecked_Union): Check flag on Implementation_Base_Type.
19395 (Is_Known_Null): New flag
19396 (Has_Pragma_Pure): New flag
19397 (No_Return): Present in all entities, set only for procedures
19398 (Is_Limited_Type): A type whose ancestor is an interface is limited if
19399 explicitly declared limited.
19400 (DT_Offset_To_Top_Func): New attribute that is present in E_Component
19401 entities. Only used for component marked Is_Tag. If present it stores
19402 the Offset_To_Top function used to provide this value in tagged types
19403 whose ancestor has discriminants.
19405 * exp_ch2.adb: Update status of new Is_Known_Null flag
19407 * sem_ch7.adb: Maintain status of new Is_Known_Null flag
19409 * sem_cat.adb (Get_Categorization): Don't treat function as Pure in
19410 the categorization sense if Is_Pure was set by pragma Pure_Function.
19412 2006-02-13 Quentin Ochem <ochem@adacore.com>
19413 Olivier Hainque <hainque@adacore.com>
19415 * bindusg.adb: Updated documentation for -d and -D switches.
19417 * raise.h (__gnat_set_globals): added new parameter for
19418 Default_Stack_Size.
19420 * init.c (__gnat_adjust_context_for_raise) <alpha-vms case>: Implement.
19421 (__gnat_handle_vms_condition): Adjust context before raise.
19422 (__gnat_install_handler): Restore the global vector setup for GCC
19423 versions before 3.4, as the frame based circtuitry is not available
19425 (__gnat_set_globals): added a parameter default_stack_size
19426 (__gl_default_stack_size): new variable.
19428 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19430 * exp_aggr.adb (Build_Array_Aggr_Code): Rename variable
19431 "Others_Mbox_Present" to "Others_Box_Present" because the mbox concept
19432 does not exist in the Ada RM.
19433 (Compatible_Int_Bounds): Determine whether two integer range bounds
19434 are of equal length and have the same start and end values.
19435 (Is_Int_Range_Bounds): Determine whether a node is an integer range.
19436 (Build_Record_Aggr_Code): Perform proper sliding of a nested array
19437 aggregate when it is part of an object declaration.
19438 (Build_Record_Aggr_Code) If the aggregate ttype is a derived type that
19439 constrains discriminants of its parent, add explicitly the discriminant
19440 constraints of the ancestor by retrieving them from the
19441 stored_constraint of the parent.
19443 2006-02-13 Robert Dewar <dewar@adacore.com>
19445 * exp_attr.adb (Expand_N_Attribute_Reference, case Mechanism_Code): If
19446 attribute Mechanism_Code is applied to renamed subprogram, modify
19447 prefix to point to base subprogram.
19448 Max/Min attributes now violate Restriction No_Implicit_Conditionals
19450 * sinfo.ads: Document that Mechanism_Code cannot be applied to
19451 renamed subprograms so that the front-end must replace the prefix
19454 2006-02-13 Javier Miranda <miranda@adacore.com>
19455 Gary Dismukes <dismukes@adacore.com>
19457 * exp_ch3.adb (Component_Needs_Simple_Initialization): Add check for
19458 availability of RE_Interface_Tag.
19459 (Build_Initialization_Call): Fix wrong access to the discriminant value.
19460 (Freeze_Record_Type): Do not generate the tables associated with
19461 timed and conditional dispatching calls through synchronized
19462 interfaces if compiling under No_Dispatching_Calls restriction.
19463 When compiling for Ada 2005, for a nonabstract
19464 type with a null extension, call Make_Controlling_Function_Wrappers
19465 and insert the wrapper function declarations and bodies (the latter
19466 being appended as freeze actions).
19467 (Predefined_Primitive_Bodies): Do not generate the bodies of the
19468 predefined primitives associated with timed and conditional
19469 dispatching calls through synchronized interfaces if we are
19470 compiling under No_Dispatching_Calls.
19471 (Build_Init_Procedure): Use RTE_Available to check if a run-time
19472 service is available before generating a call.
19473 (Make_Controlling_Function_Wrappers): New procedure.
19474 (Expand_N_Full_Type_Declaration): Create a class-wide master for
19475 access-to-limited-interfaces because they can be used to reference
19476 tasks that implement such limited interface.
19477 (Build_Offset_To_Top_Functions): Build the tree corresponding to the
19478 procedure spec and body of the Offset_To_Top function that is generated
19479 when the parent of a type with discriminants has secondary dispatch
19481 (Init_Secondary_Tags): Handle the case in which the parent of the type
19482 containing secondary dispatch tables has discriminants to generate the
19483 correct arguments to call Set_Offset_To_Top.
19484 (Build_Record_Init_Proc): Add call to Build_Offset_To_Top_Functions.
19486 * a-tags.ads, a-tags.adb: (Check_Index): Removed.
19487 Add Wide_[Wide_]Expanded_Name.
19488 (Get_Predefined_Prim_Op_Address): New subprogram that provides exactly
19489 the same functionality of Get_Prim_Op_Address but applied to predefined
19490 primitive operations because the pointers to the predefined primitives
19491 are now saved in a separate table.
19492 (Parent_Size): Modified to get access to the separate table of primitive
19493 operations or the parent type.
19494 (Set_Predefined_Prim_Op_Address): New subprogram that provides the same
19495 functionality of Set_Prim_Op_Address but applied to predefined primitive
19497 (Set_Signature): New subprogram used to store the signature of a DT.
19498 (Displace): If the Offset_To_Top value is not static then call the
19499 function generated by the expander to get such value; otherwise use
19500 the value stored in the table of interfaces.
19501 (Offset_To_Top): The type of the actual has been changed to Address to
19502 give the correct support to tagged types with discriminants. In this
19503 case this value is stored just immediately after the tag field.
19504 (Set_Offset_To_Top): Two new formals have been added to indicate if the
19505 offset_to_top value is static and hence pass this value to the run-time
19506 to store it in the table of interfaces, or else if this value is dynamic
19507 and then pass to the run-time the address of a function that is
19508 generated by the expander to provide this value for each object of the
19511 * rtsfind.ads (Default_Prin_Op_Count): Removed.
19512 (Default_Prim_Op_Count): New entity
19513 (Get_Predefined_Prim_Op_Address): New entity
19514 (Set_Predefined_Prim_Op_Address): New entity
19515 (RE_Set_Signature): New entity
19517 2006-02-13 Thomas Quinot <quinot@adacore.com>
19518 Ed Schonberg <schonberg@adacore.com>
19520 * exp_ch4.adb (Expand_Allocator_Expression): Pass Allocator => True to
19521 Make_Adjust_Call done for a newly-allocated object.
19523 * exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): If the statements
19524 in a subprogram are wrapped in a cleanup block, indicate that the
19525 subprogram contains an inner block with an exception handler.
19526 (Make_Adjust_Call): New Boolean formal Allocator indicating whether the
19527 Adjust call is for a newly-allocated object. In that case we must not
19528 assume that the finalization list chain pointers are correct (since they
19529 come from a bit-for-bit copy of the original object's pointers) so if
19530 the attach level would otherwise be zero (no change), we set it to 4
19531 instead to cause the pointers to be reset to null.
19533 * s-finimp.adb (Attach_To_Final_List): New attach level: 4, meaning
19534 reset chain pointers to null.
19536 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19538 * exp_ch5.adb (Expand_Assign_Array): If the right-hand side is a
19539 string, and the context requires a loop for the assignment (e.g.
19540 because the left-hand side is packed), generate a unique name for the
19541 temporary that holds the string, to prevent spurious name clashes.
19543 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19544 Javier Miranda <miranda@adacore.com>
19545 Robert Dewar <dewar@adacore.com>
19546 Gary Dismukes <dismukes@adacore.com>
19548 * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
19549 return unconstrained arrays.
19551 (Expand_Call): An indirect call through an access parameter of a
19552 protected operation is not a protected call.
19553 Add circuit to raise CE in Ada 2005 mode following call
19554 to Raise_Exception.
19555 (Register_DT_Entry): Do nothing if
19556 the run-time does not give support to abstract interfaces.
19557 (Freeze_Subprogram): In case of dispatching operations, do not generate
19558 code to register the operation in the dispatch table if the source
19559 is compiled with No_Dispatching_Calls.
19560 (Register_Predefined_DT_Entry): Generate code that calls the new
19561 run-time subprogram Set_Predefined_Prim_Op_Address instead of
19562 Set_Prim_Op_Address.
19564 * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length checks
19565 on array assignments if the right-hand side is a function call that has
19566 been inlined. Check is performed on the assignment in the block.
19567 (Process_Bounds): If bounds and range are overloaded, apply preference
19568 rule for root operations to disambiguate, and diagnose true ambiguity.
19569 (Analyze_Assignment): Propagate the tag for a class-wide assignment with
19570 a tag-indeterminate right-hand side even when Expander_Active is True.
19571 Needed to ensure that dispatching calls to T'Input are allowed and
19572 get the tag of the target class-wide object.
19574 * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
19575 an inherited primitive operation that already overrides several
19576 abstract interface primitives. For transitivity, the new entity must
19577 also override all the abstract interface primitives covered by the
19578 inherited overriden primitive.
19579 Emit warning if new entity differs from homograph in same scope only in
19580 that one has an access parameter and the other one has a parameter of
19581 a general access type with the same designated type, at the same
19582 position in the signature.
19583 (Make_Inequality_Operator): Use source locations of parameters and
19584 subtype marks from corresponding equality operator when creating the
19585 tree structure for the implicit declaration of "/=". This does not
19586 change anything in behaviour except that the decoration of the
19587 components of the subtree created for "/=" allows ASIS to get the
19588 string images of the corresponding identifiers.
19589 (Analyze_Return_Statement): Remove '!' in warning message.
19590 (Check_Statement_Sequence): Likewise.
19591 (Analyze_Subprogram_Body): For an access parameter whose designated type
19592 is an incomplete type imported through a limited_with clause, use the
19593 type of the corresponding formal in the body.
19594 (Check_Returns): Implicit return in No_Return procedure now raises
19595 Program_Error with a compile time warning, instead of beging illegal.
19596 (Has_Single_Return): Function returning unconstrained type cannot be
19597 inlined if expression in unique return statement is not an identifier.
19598 (Build_Body_To_Inline): It is possible to inline a function call that
19599 returns an unconstrained type if all return statements in the function
19600 return the same local variable. Subsidiary procedure Has_Single_Return
19601 verifies that the body conforms to this restriction.
19603 * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
19604 same type, and one of them is of an anonymous access type, convert
19605 the other operand to it, so that this is a valid binary operation for
19607 (Resolve_Type_Conversion): Handle subtypes of protected types and
19608 task types when accessing to the corresponding record type.
19609 (Resolve_Allocator): Add '\' in 2-line warning message.
19610 Remove '!' in warning message.
19611 (Resolve_Call): Add '\' in 2-line warning message.
19612 (Valid_Conversion): Likewise.
19613 (Resolve_Overloaded_Selected_Component): If disambiguation succeeds, the
19614 resulting type may be an access type with an implicit dereference.
19615 Obtain the proper component from the designated type.
19616 (Make_Call_Into_Operator): Handle properly a call to predefined equality
19617 given by an expanded name with prefix Standard, when the operands are
19618 of an anonymous access type.
19619 (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
19620 Explicit_Dereference and Resolve_Selected_Component, to verify that the
19621 prefix of the expression is not of an incomplete type. Allows full
19622 diagnoses of all semantic errors.
19623 (Resolve_Actuals): If the actual is an allocator whose directly
19624 designated type is a class-wide interface we build an anonymous
19625 access type to use it as the type of the allocator. Later, when
19626 the subprogram call is expanded, if the interface has a secondary
19627 dispatch table the expander will add a type conversion to force
19628 the displacement of the pointer.
19629 (Resolve_Call): If a function that returns an unconstrained type is
19630 marked Inlined_Always and inlined, the call will be inlined and does
19631 not require the creation of a transient scope.
19632 (Check_Direct_Boolean_Op): Removed
19633 (Resolve_Comparison_Op): Remove call to above
19634 (Resolve_Equality_Op): Remove call to above
19635 (Resolve_Logical_Op): Inline above, since this is only call.
19636 (Valid_Conversion): Handle properly conversions between arrays of
19637 convertible anonymous access types.
19640 (Set_Literal_String_Subtype): If the lower bound is not static, wrap
19641 the literal in an unchecked conversion, because GCC 4.x needs a static
19642 value for a string bound.
19644 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19645 Hristian Kirtchev <kirtchev@adacore.com>
19647 * exp_ch9.adb (Expand_N_Protected_Type_Declaration): When creating the
19648 components of the corresponding record, take into account component
19649 definitions that are access definitions.
19650 (Expand_N_Asynchronous_Select): A delay unit statement rewritten as a
19651 procedure is not considered a dispatching call and will be expanded
19654 2006-02-13 Javier Miranda <miranda@adacore.com>
19656 * exp_disp.ads, exp_disp.adb (Expand_Dispatching_Call): If the
19657 controlling argument of the dispatching call is an abstract interface
19658 class-wide type then we use it directly.
19659 Check No_Dispatching_Calls restriction.
19660 (Default_Prim_Op_Position): Remove the code that looks for the last
19661 entity in the list of aliased subprograms. This code was wrong in
19663 (Fill_DT_Entry): Add assertion to avoid the use of this subprogram
19664 when the source is compiled with the No_Dispatching_Calls restriction.
19665 (Init_Predefined_Interface_Primitives): No need to inherit primitives
19666 if we are compiling with restriction No_Dispatching_Calls.
19667 (Make_Disp_XXX): Addition of assertion to avoid the use of all these
19668 subprograms if we are compiling under No_Dispatching_Calls restriction.
19669 (Make_DT): Generate a dispatch table with a single dummy entry if
19670 we are compiling with the No_Dispatching_Calls restriction. In
19671 addition, in this case we don't generate code that calls to the
19672 following run-time subprograms: Set_Type_Kind, Inherit_DT.
19673 (Make_Select_Specific_Data_Table): Add assertion to avoid the use
19674 of this subprogram if compiling with the No_Dispatching_Calls
19676 (Expand_Type_Conversion): Instead of using the actual parameter,
19677 the argument passed as parameter to the conversion function was
19678 erroneously referenced by the expander.
19679 (Ada_Actions): Addition of Get_Predefined_Prim_Op_Address,
19680 Set_Predefined_Primitive_Op_Address and Set_Signature.
19681 (Expand_Dispatching_Call): Generate call to
19682 Get_Predefined_Prim_Op_Address for predefined primitives.
19683 (Fill_DT_Entry): Generate call to Set_Predefined_Prim_Op_Address for
19684 predefined primitives.
19685 (Make_DT, Make_Secondary_DT): If the tagged type has no user defined
19686 primitives we reserve one dummy entry to ensure that the tag does not
19687 point to some memory that is associated with some other object. In
19688 addition, remove all the old code that generated the assignments
19689 associated with the signature of the dispatch table and replace them
19690 by a call to the new subprogram Set_Signature.
19691 (Set_All_DT_Position): Change the algorithm because now we have a
19692 separate dispatch table associated with predefined primitive operations.
19693 (Expand_Interface_Conversion): In case of non-static offset_to_top
19694 add explicit dereference to get access to the object after the call
19695 to displace the pointer to the object.
19696 (Expand_Interface_Thunk): Modify the generation of the actual used
19697 in the calls to the run-time function Offset_To_Top to fulfil its
19699 (Make_DT): Add the new actuals required to call Set_Offset_To_Top.
19701 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19703 * exp_dist.adb (Copy_Specification): For access parameters, copy
19704 Null_Exclusion flag, which will have been set for stream subprograms
19707 2006-02-13 Pascal Obry <obry@adacore.com>
19709 * expect.c (__gnat_expect_portable_execvp): New implementation. The
19710 previous implementation was using the C runtime spawnve routine but
19711 the corresponding wait was using directly the Win32 API. This was
19712 causing some times a lock when waiting for an event using
19713 WaitForSingleObject in __gnat_waitpid. This new implementation uses
19714 the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
19715 API fixes this problem.
19717 2006-02-13 Robert Dewar <dewar@adacore.com>
19719 * exp_intr.adb (Expand_Unc_Deallocation): Correct error of bad analyze

19726 * exp_pakd.adb (Convert_To_PAT_Type): For the case of a bit packed
19727 array reference that is an explicit dereference, mark the converted
19728 (packed) array reference as analyzed to prevent a forthcoming
19729 reanalysis from resetting its type to the original (non-packed) array

19738 searching for the predefined equality operator, verify that operands
19739 have the same type.
19740 (Is_Predefined_Dispatching_Operation): Remove the code that looks
19741 for the last entity in the list of aliased subprograms. This code
19742 was wrong in case of renamings.
19743 (Set_Renamed_Subprogram): New procedure
19744 (Remove_Side_Effects): Replace calls to Etype (Exp) with use of the
19745 Exp_Type constant computed when entering this subprogram.

19749 (Side_Effect_Free): An attribute reference 'Input is not free of
19750 side effect, unlike other attributes that are functions. (from code
19752 (Remove_Side_Effects): Expressions that involve packed arrays or records
19753 are copied at the point of reference, and therefore must be marked as
19754 renamings of objects.
19755 (Is_Predefined_Dispatching_Operation): Return false if the operation is
19756 not a dispatching operation.
19759 (Remove_Side_Effects): Lift enclosing type conversion nodes for
19760 elementary types in all cases.
19762 2006-02-13 Javier Miranda <miranda@adacore.com>

19776 * g-catiio.adb (Sec_Number): New type used to compute the number of
19777 seconds since 1-1-1970.
19778 (Image) [Natural]: The parameter was an Integer, as we can't deal with
19779 negative numbers (years, months...) it is better to have a Natural here.
19781 (Image) [Number]: Change parameter from Long_Integer to Number.
19782 (Image): Use Number type to compute the seconds since 1-1-1970 to fix an
19783 overflow for dates past year 2038.
19785 2006-02-13 Matthew Heaney <heaney@adacore.com>
19787 * g-dyntab.adb (Index_Of): conversion from Natural can no longer raise

19792 * gnatbind.adb (Scan_Bind_Arg): Replace error by warning on -M and
19794 (Gnatbind): Do not call Exit_Program (E_Success) at the end, so that
19795 finalization can occur normally.

19799 * gnatcmd.adb (Rules_Switches): New table
19800 (Add_To_Rules_Switches): New procedure
19801 (GNATCmd): For command CHECK, put all options following "-rules" in the
19802 Rules_Switches table. Append these -rules switches after the -cargs
19805 2006-02-13 Robert Dewar <dewar@adacore.com>
19807 * g-spipat.adb (Image, case PC_Assign_Imm and case PC_Assign_OnM):
19808 These two cases were generating incorrect output, and if this unit
19809 was built with checks on, generated a discriminant mismatch constraint
19812 2006-02-13 Ed Schonberg <schonberg@adacore.com>
19813 Robert Dewar <dewar@adacore.com>
19815 * lib-xref.adb (Get_Type_Reference): For a private type whose full
19816 view is an array type, indicate the component type as well, for
19817 navigation purposes.
19818 (Generate_Reference): Don't consider array ref on LHS to be a case
19819 of violating pragma Unreferenced.
19820 Do not give Ada 2005 warning except on real reference.
19822 2006-02-13 Vincent Celier <celier@adacore.com>
19824 * make.adb (Collect_Arguments_And_Compile): For VMS, when compiling the
19825 main source, add switch -mdebug-main=_ada_ so that the executable can
19826 be debugged by the standard VMS debugger.
19827 (Gnatmake): Set No_Main_Subprogram to True when there is no main
19828 subprogram, to avoid issuing -mdebug-main=_ada_ for VMS uselessly.
19829 Exit the Multi_Main_Loop when Unique_Compile is True after compilation
19830 of the last source, as the binding and linking phases are never
19832 Set all executable obsolete when rebuilding a library.
19834 * makeutl.adb (Linker_Options_Switches): Do not process empty linker
19837 2006-02-13 Javier Miranda <miranda@adacore.com>
19840 * par-ch3.adb (P_Derived_Type_Def_Or_Private_Ext_Decl): Reorganize the
19841 code to improve the error message reported when the program has
19842 declarations of abstract interface types and it is not compiled with
19843 the -gnat05 switch.
19844 (P_Access_Definition): Reorganize the code to improve the error
19845 message reported when the new Ada 2005 syntax for anonymous
19846 access types is used and the program is not compiled with the

19869 * prj-nmsc.ads, prj-nmsc.adb (Error_Msg): If location parameter is
19870 unknown, use the location of the project to report the error.
19871 (When_No_Sources): New global variable
19872 (Report_No_Ada_Sources): New procedure
19873 (Check): New parameter When_No_Sources. Set value of global variable
19875 (Find_Sources): Call Report_No_Ada_Sources when appropriate
19876 (Get_Sources_From_File): Ditto
19877 (Warn_If_Not_Sources): Better warning messages indicating the unit name
19880 * prj-pars.ads, prj-pars.adb (Parse): New parameter When_No_Sources.
19881 Call Prj.Proc.Process with parameter When_No_Sources.
19883 * prj-proc.ads, prj-proc.adb (Check): New parameter When_No_Sources.
19884 Call Recursive_Check with parameter When_No_Sources.
19885 (Recursive_Check): New parameter When_No_Sources. Call itself and
19886 Prj.Nmsc.Check with parameter When_No_Sources.
19887 (Process): New parameter When_No_Sources. Call Check with parameter
19889 (Copy_Package_Declarations): New procedure to copy renamed parameters

19899 When removing nodes (attributes Source_Dirs, Source_Files,
19900 Source_List_File and package Naming), save the comments and attach the
19901 saved comments to the newly created nodes.
19902 Do not add a with clause for the naming package if one already exists.

19911 aliased entities to look for the overriden abstract interface
19913 (Is_Interface_Subprogram): Complete documentation.
19914 (Check_Dispatching_Operation): Do not generate code to register the
19915 operation in the dispatch table if the source is compiled with
19916 restriction No_Dispatching_Calls.

19918 No_Return procedure with procedure that is not No_Return
19919 (Check_Dispatching_Call): Suppress the check for an abstract operation
19920 when the original node of an actual is a tag-indeterminate attribute
19921 call, since the attribute, which must be 'Input, can never be abstract.
19922 (Is_Tag_Indeterminate): Handle checking of tag indeterminacy of a
19923 call to the Input attribute (even when rewritten).
19924 (Propagate_Tag): Augment comment to indicate the possibility of a call
19925 to an Input attribute.
19927 * sem_disp.ads (Override_Dispatching_Operation): Moved to spec to allow
19928 calling it from Exp_Ch3.Make_Controlling_Function_Wrappers.

19937 * s-auxdec-vms_64.ads (Short_Address): Wrap it in a type.
19939 2006-02-13 Javier Miranda <miranda@adacore.com>
19941 * sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
19942 handles default-initialized components to keep separate the management
19943 of this feature but also avoid the unrequired resolution and
19944 expansion of components that do not have partially initialized
19946 (Collect_Aggr_Bounds): Add '\' in 2-line warning message.
19947 (Check_Bounds): Likewise.
19948 (Check_Length): Likewise.
19950 2006-02-13 Javier Miranda <miranda@adacore.com>
19951 Ed Schonberg <schonberg@adacore.com>
19953 * sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
19954 abstract interface type call analyze_and_resolve to expand the type
19955 conversion into the corresponding displacement of the
19956 reference to the base of the object.
19957 (Eval_Attribute, case Width): For systems where IEEE extended precision
19958 is supported, the maximum exponent occupies 4 decimal digits.
19959 (Accessibility_Message): Add '\' in 2-line warning message.
19960 (Resolve_Attribute): Likewise.
19961 (case Attribute_Access): Significantly revise checks
19962 for illegal access-to-subprogram Access attributes to properly enforce
19963 the rules of 3.10.2(32/2).
19964 Diagnose use of current instance with an illegal attribute.
19966 * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
19968 (Enclosing_Generic_Unit): New function to return a node's innermost
19969 enclosing generic declaration node.
19970 (Compile_Time_Constraint_Error): Remove '!' in warning messages.
19971 (Type_Access_Level): The accessibility level of anonymous acccess types
19972 associated with discriminants is that of the current instance of the
19973 type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
19974 (Compile_Time_Constraint_Error): Handle case of conditional expression.
19975 (Kill_Current_Values_For_Entity): New function
19976 (Enter_Name): Change formal type to Entity_Id
19978 2006-02-13 Hristian Kirtchev <kirtchev@adacore.com>

19982 * sem_ch10.adb (Check_Redundant_Withs): New procedure in
19983 Analyze_Compilation_Unit.
19984 Detect and warn on redundant with clauses detected in a package spec
19985 and/or body when -gnatwr is used.
19986 (Analyze_Context): Analyze config pragmas before other items
19987 (Install_Context_Items): Don't analyze config pragmas here
19988 (Install_Limited_Withed_Unit): Set limited entity of package in
19989 with_clause so that cross-reference information or warning messages on
19990 unused packages can be properly generated
19991 (Is_Visible_Through_Renamings): Return false if the limited_with_clause
19992 has Error_Posted set. Prevent infinite loops in illegal programs.
19993 (Check_Private_Child_Unit): Move test for a nonprivate with clause down
19994 to the point of the error test requiring the current unit to be private.
19995 This ensures that private with clauses are not exempted from the basic
19996 checking for being a descendant of the same library unit parent as a
19997 withed private descendant unit.
19998 (Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
19999 handle private with clauses properly, as well as to account for cases
20000 where the withed unit is a public descendant of a private ancestor
20001 (in which case the current unit must be a descendant of the private
20002 ancestor's parent). The spec comments were updated accordingly. Also,
20003 the old error message in this subprogram was replaced with error
20004 messages that mirror the errors tested and reported by
20005 Check_Private_Child_Unit.
20006 Parameter and variable names improved for readability.
20007 (Install_Limited_Context_Clauses): Remove test for a withed unit being
20008 private as the precondition for calling
20009 Check_Private_Limited_Withed_Unit since that subprogram has been
20010 revised to test public units as well as private units.

20015 Javier Miranda <miranda@adacore.com>
20017 * sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
20018 that Scope_Stack.First = 1.
20019 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20020 were not always properly handled previously.
20021 (Formal_Entity): Complete rewrite, to handle properly some complex case
20022 with multiple levels of parametrization by formal packages.
20023 (Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
20024 to the corresponding derived type declaration for proper semantics.
20026 * sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
20027 (Check_Component): Enforce restriction on components of
20028 unchecked_unions: a component in a variant cannot contain tasks or
20030 (Unchecked_Union): Allow nested variants and multiple discriminants, to
20032 Add pragma Ada_2005 (synonym for Ada_05)
20033 Properly handle Ada_Version_Explicit and Ada_Version_Config, which
20034 were not always properly handled previously.
20035 Document that pragma Propagate_Exceptions has no effect
20036 (Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
20037 (Set_Convention_From_Pragma): Check that if a convention is
20038 specified for a dispatching operation, then it must be
20039 consistent with the existing convention for the operation.
20040 (CPP_Class): Because of the C++ ABI compatibility, the programmer is no
20041 longer required to specify an vtable-ptr component in the record. For
20042 compatibility reasons we leave the support for the previous definition.
20043 (Analyze_Pragma, case No_Return): Allow multiple arguments
20045 * sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
20046 non-overrideen inherited operation with a controlling result as
20047 illegal only its implicit declaration comes from the derived type
20048 declaration of its result's type.
20049 (Check_Possible_Deferred_Completion): Relocate the object definition
20050 node of the subtype indication of a deferred constant completion rather
20051 than directly analyzing it. The analysis of the generated subtype will
20052 correctly decorate the GNAT tree.
20053 (Record_Type_Declaration): Check whether this is a declaration for a
20054 limited derived record before analyzing components.
20055 (Analyze_Component_Declaration): Diagnose record types not explicitly
20056 declared limited when a component has a limited type.
20057 (Build_Derived_Record_Type): Code reorganization to check if some of
20058 the inherited subprograms of a tagged type cover interface primitives.
20059 This check was missing in case of a full-type associated with a private
20061 (Constant_Redeclaration): Check that the subtypes of the partial and the
20062 full view of a constrained deferred constant statically match.
20063 (Mentions_T): A reference to the current type in an anonymous access
20064 component declaration must be an entity name.
20065 (Make_Incomplete_Type_Declaration): If type is tagged, set type of
20066 class_wide type to refer to full type, not to the incomplete one.
20067 (Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
20068 available. Required to give support to the certified run-time.
20069 (Analyze_Component_Declaration): In case of anonymous access components
20070 perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
20071 (Process_Discriminants): For an access discriminant, use the
20072 discriminant specification as the associated_node_for_itype, to
20073 simplify accessibility checks.
20075 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20076 Javier Miranda <miranda@adacore.com>
20078 * sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
20079 abstract interpretations on an operator, remove interpretations that
20080 yield Address or a type derived from it, if one of the operands is an
20082 (Try_Object_Operation.Try_Primitive_Operation,
20083 Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
20084 location when creating the new reference to a primitive or class-wide
20085 operation as a part of rewriting a subprogram call.
20086 (Try_Primitive_Operations): If context requires a function, collect all
20087 interpretations after the first match, because there may be primitive
20088 operations of the same type with the same profile and different return
20089 types. From code reading.
20090 (Try_Primitive_Operation): Use the node kind to choose the proper
20091 operation when a function and a procedure have the same parameter
20093 (Complete_Object_Operation): If formal is an access parameter and prefix
20094 is an object, rewrite as an Access reference, to match signature of
20095 primitive operation.
20096 (Find_Equality_Type, Find_One_Interp): Handle properly equality given
20097 by an expanded name with prefix Standard, when the operands are of an
20098 anonymous access type.
20099 (Remove_Abstract_Operations): If the operation is abstract because it is
20100 inherited by a user-defined type derived from Address, remove it as
20101 well from the set of candidate interpretations of an overloaded node.
20102 (Analyze_Membership_Op): Membership test not applicable to cpp-class
20105 2006-02-13 Bob Duff <duff@adacore.com>
20107 * sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
20108 redundant use clauses.
20109 In particular, if the scope of two use clauses overlaps, but one is not
20110 entirely included in the other, we should not warn. This can happen
20111 with nested packages.
20112 (Analyze_Subprogram_Renaming): Protect the compiler against previously
20113 reported errors. The bug was reported when the compiler was built
20114 with assertions enabled.
20115 (Find_Type): If the node is a 'Class reference and the prefix is a
20116 synchronized type without a corresponding record, return the type
20119 2006-02-13 Javier Miranda <miranda@adacore.com>
20121 * sem_ch9.adb (Analyze_Protected_Type, Analyze_Task_Type): Check that
20122 if this is the full-declaration associated with a private declaration
20123 that implement interfaces, then the private type declaration must be
20125 (Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object
20126 as aliased. The use of the 'access attribute is not available for such
20127 object (for this purpose the object should be explicitly marked as
20128 aliased, but being an anonymous type this is not possible).
20130 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20131 Robert Dewar <dewar@adacore.com>
20133 * sem_elab.adb (Same_Elaboration_Scope): A package that is a
20134 compilation unit is an elaboration scope.
20135 (Add_Task_Proc): Add '\' in 2-line warning message.
20136 (Activate_All_Desirable): Deal with case of unit with'ed by parent
20138 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20139 Javier Miranda <miranda@adacore.com>
20141 * sem_type.adb (Write_Overloads): Improve display of candidate
20143 (Add_One_Interp): Do not add to the list of interpretations aliased
20144 entities corresponding with an abstract interface type that is an
20145 immediate ancestor of a tagged type; otherwise we have a dummy
20146 conflict between this entity and the aliased entity.
20147 (Disambiguate): The predefined equality on universal_access is not
20148 usable if there is a user-defined equality with the proper signature,
20149 declared in the same declarative part as the designated type.
20150 (Find_Unique_Type): The universal_access equality operator defined under
20151 AI-230 does not cover pool specific access types.
20152 (Covers): If one of the types is a generic actual subtype, check whether
20153 it matches the partial view of the other type.
20155 2006-02-13 Thomas Quinot <quinot@adacore.com>
20157 * sinput-d.adb (Write_Line): Update the Source_Index_Table after each
20158 line. This is necessary to allow In_Extended_Main_Unit to provide
20159 correct results for itypes while writing out expanded source.
20160 (Close_File): No need to update the source_index_table here since it's
20161 now done for each line.
20163 2006-02-13 Ed Schonberg <schonberg@adacore.com>
20164 Robert Dewar <dewar@adacore.com>
20166 * sprint.adb (Write_Itype): Preserve Sloc of declaration, if any, to
20167 preserve the source unit where the itype is declared, and prevent a
20169 (Note_Implicit_Run_Time_Call): New procedure
20170 (Write_Itype): Handle missing cases (E_Class_Wide_Type and
20173 * sprint.ads: Document use of $ for implicit run time routine call
20175 2006-02-13 Quentin Ochem <ochem@adacore.com>
20177 * s-stausa.adb (Initialize_Analyzer): fixed error in assignment of
20180 2006-02-13 Bob Duff <duff@adacore.com>
20182 * s-valint.adb (Scan_Integer): Call Scan_Raw_Unsigned instead of
20183 Scan_Unsigned, so we do not scan leading blanks and sign twice.
20184 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20185 raise Constraint_Error.
20187 * s-vallli.adb (Scan_Long_Long_Integer): Call
20188 Scan_Raw_Long_Long_Unsigned instead of Scan_Long_Long_Unsigned, so we
20189 do not scan leading blanks and sign twice.
20190 Integer'Value("- 5") and Integer'Value("-+5") now correctly
20191 raise Constraint_Error.
20193 * s-valllu.ads, s-valllu.adb (Scan_Raw_Long_Long_Unsigned,
20194 Scan_Long_Long_Unsigned): Split out most of the processing from
20195 Scan_Long_Long_Unsigned out into
20196 Scan_Raw_Long_Long_Unsigned, so that Val_LLI can call the Raw_ version.

20406 * a-taster.ads, a-taster.adb: New files.
20408 * a-elchha.adb (Last_Chance_Handler): Change the task termination soft
20409 link to the version that does nothing. This way the task termination
20410 routine is not executed twice for the environment task when finishing
20411 because of an unhandled exception.
20413 * a-exextr.adb (Notify_Unhandled_Exception): Call the task termination
20414 handler because of an unhandled exception.
20416 * a-taside.adb (Abort_Tasks): Call the Abort_Tasks procedure from

20422 * s-soflin.ads, s-soflin.adb (Task_Termination_NT): Add this
20423 non-tasking version of the soft link for task termination. We do
20424 nothing since if we are using the non-tasking version it
20425 means that the task termination functionality is not used.
20426 (Null_Finalize_Global_List): Add this null version for the procedure
20427 in charge of finalizing the global list for controlled objects.
20428 (Null_Adafinal): Remove this procedure. Adafinal_NT has been created
20429 instead for handling run-time termination in a more flexible way.
20430 (Adafinal_NT): This new procedure will take care of finalizing the
20431 global list for controlled objects if needed, but no tasking
20434 * s-tarest.adb (Task_Lock): Do not try to lock again the
20435 Global_Task_Lock if we already own it. Otherwise, we get blocked in
20436 some run-time operations.
20437 (Task_Unlock): Do not try to actually unlock the Global_Task_Lock
20438 until all nested locks have been released.
20439 (Task_Wrapper): Call the fall-back task termination handler. It
20440 applies to all tasks but the environment task.
20441 (Finalize_Global_Tasks): Add the call for the task termination
20442 procedure for the environment task.
20443 (Task_Wrapper): suppress warnings around declaration of
20444 Secondary_Stack_Address.
20446 * s-tasini.adb (Final_Task_Unlock): Global_Task_Lock_Nesting has been
20447 moved to the Common_ATCB record.
20448 (Task_Lock): Global_Task_Lock_Nesting has been moved to the
20449 Common_ATCB record.
20450 (Task_Unlock): Global_Task_Lock_Nesting has been moved to the
20451 Common_ATCB record.
20453 * s-taskin.adb (Initialize_ATCB): Initialize Global_Task_Lock_Nesting,
20454 Fall_Back_Handler, and Specific_Handler.
20456 * s-taskin.ads (Cause_Of_Termination): Redefine this type here, already
20457 defined in Ada.Task_Termination, to avoid circular dependencies.
20458 (Termination_Handler): Redefine this type here, alredy defined in
20459 Ada.Task_Termination, for avoiding circular dependencies.
20460 (Common_ATCB): Add the Fall_Back_Handler and Specific_Handler required
20461 for storing task termination handlers. In addition,
20462 Global_Task_Lock_Nesting has been moved from Ada_Task_Control_Block to
20463 Common_ATCB because it is used by both the regular and the restricted
20465 (Ada_Task_Control_Block): Move Global_Task_Lock_Nesting from here to
20466 Common_ATCB because it is used by both the regular and the restricted
20468 (Common_ATCB): Added a dynamic task analyzer field.
20470 * s-tassta.adb (Abort_Tasks): Move the code in charge of checking
20471 potentially blocking operations to System.Tasking.Utilities.Abort_Tasks.
20472 (Task_Wrapper): Call the task termination handler. It applies to all
20473 tasks but the environment task.
20474 (Finalize_Global_Tasks): Call the task termination procedure for the
20475 environment task. The call to Finalize_Global_List is now performed
20476 using the soft links mechanism.
20477 (Task_Wrapper): added dynamic stack analysis.
20479 * s-tasuti.adb (Abort_Tasks): The code in charge of checking
20480 potentially blocking operations has been moved from
20481 System.Tasking.Stages.Abort_Tasks to this procedure. There can be
20482 direct calls to System.Tasking.Utilities.Abort_Tasks that do not pass
20483 through System.Tasking.Stages.Abort_Tasks, and we do not want to miss
20484 this run-time check.
20486 * s-solita.adb (Task_Termination_Handler_T): Add this task-safe version
20487 of task termination procedure.
20488 (Init_Tasking_Soft_Links): Install the task-safe version of the soft
20489 link for the task termination procedure.

20505 (Standart_Output): new subprogram
20506 (Set_Output): new subprogram
20507 (Put): now uses the value of Current_Out to know if the output has to be
20508 send to stderr or stdout.

20530 * a-tags.ads, a-tags.adb (Offset_To_Top): Moved from the package body
20531 to the specification because the frontend generates code that uses this
20533 (Set_Interface_Table): Add missing assertion.
20534 Update documentation describing the run-time structure.
20535 (Displace): New subprogram that displaces the pointer to the object
20536 to reference one of its secondary dispatch tables.
20537 (IW_Membership): Modified to use the new table of interfaces.
20538 (Inherit_TSD): Modified to use the new table of interfaces.
20539 (Register_Interface_Tag): Use the additional formal to fill the
20540 contents of the new table of interfaces.
20541 (Set_Interface_Table): New subprogram that stores in the TSD the
20542 pointer to the table of interfaces.

20556 * exp_ch6.adb (Register_Interface_DT_Entry): Remove the Thunk_Id actual
20557 in all the calls to Expand_Interface_Thunk. Instead of referencing the
20558 record component containing the tag of the secondary dispatch table we
20559 have to use the Offset_To_Top run-time function to get this information;
20560 otherwise if the pointer to the base of the object has been displace
20561 we get a wrong value if we use the 'position attribute.
20563 * exp_disp.adb (Expand_Interface_Thunk): Remove the Thunk_Id actual in
20564 all the calls to Expand_Interface_Thunk.
20565 (Make_Secondary_DT): Secondary dispatch tables do not have a table of
20566 interfaces; hence the call to Set_Interface_Table was clearly wrong.
20567 (Collect_All_Interfaces): Modify the internal subprogram Collect to
20568 ensure that the interfaces implemented by the ancestors are placed
20569 at the header of the generated list.
20570 (Expand_Interface_Conversion): Handle the case in which the displacement
20571 associated with the interface conversion is not statically known. In
20572 this case we generate a call to the new run-time subprogram Displace.
20573 (Make_DT): Generate and fill the new table of interfaces.
20574 (Ada_Actions, Action_Is_Proc, Action_Nb_Arg): Add entries for
20575 Get_Tagged_Kind and Set_Tagged_Kind.
20576 (Tagged_Kind): New function that determines the tagged kind of a type
20577 with respect to limitedness and concurrency and returns a reference to
20579 (Make_Disp_Asynchronous_Select_Body, Make_Disp_Conditional_Select_Body,
20580 Make_Disp_Timed_Select_Body): Correctly retrieve the pointer to the
20581 primary dispatch table for a type.

20583 secondary dispatch table respectively of a tagged type.
20585 * exp_disp.ads (Expand_Interface_Thunk): Remove Thunk_Id formal.
20586 (Expand_Interface_Conversion): New subprogram to indicate if the
20587 displacement of the type conversion is statically known.

20596 (RE_Id, RE_Unit_Table): Add entry for RE_Get_Tagged_Kind,
20597 Set_Tagged_Kind, RE_Tagged_Kind, RE_TK_Abstract_Limited_Tagged,
20598 RE_TK_Abstract_Tagged, RE_TK_Limited_Tagged, RE_TK_Protected,
20599 RE_TK_Tagged, RE_TK_Task.
20601 * exp_ch3.adb (Init_Secondary_Tags): Modify the subprogram
20602 Init_Secondary_Tags_Internal to allow its use with interface types and
20603 also to generate the code for the new additional actual required
20604 by Set_Offset_To_Top.
20605 (Build_Init_Statements): In case of components associated with abstract
20606 interface types there is no need to generate a call to its IP.
20607 (Freeze_Record_Type): Generate Select Specific Data tables only for
20609 (Make_Predefined_Primitive_Specs, Predefined_Primitive_Bodies): Generate
20610 the bodies and specifications of the predefined primitive operations
20611 dealing with dispatching selects and abort, 'Callable, 'Terminated only
20612 for concurrent types.
20614 * exp_sel.ads, exp_sel.adb: New files.
20616 * exp_ch9.adb (Build_Protected_Entry, Expand_N_Protected_Body,
20617 Expand_N_Protected_Type_Declaration, Make_Initialize_Protection): Handle
20618 properly protected objects and attach handler in the case of the
20619 restricted profile.
20620 Move embeded package Select_Expansion_Utilities into a separate external
20622 (Expand_N_Asynchronous_Select, Expand_N_Conditional_Select,
20623 Expand_N_Timed_Entry_Call): Correct calls external package Exp_Sel.
20624 (Build_K, Build_S_Assignment): New subprograms, part of the select
20625 expansion utilities.

20628 where the trigger is a dispatching procedure of a limited tagged type.
20630 2005-12-09 Olivier Hainque <hainque@adacore.com>
20632 * decl.c (gnat_to_gnu_entity, renaming object case): Don't early expand
20633 pointer initialization values. Make a SAVE_EXPR instead. Add comments
20634 about the use and expansion of SAVE_EXPRs in the various possible
20635 renaming handling cases.
20636 (components_to_record, compare_field_bitpos): Sort by DECL_UID, not by
20637 abusing DECL_FCONTEXT.

20674 Robert Dewar <dewar@adacore.com>
20676 * hostparm.ads (Max_Line_Length): Set to Types.Column_Number'Last - 1,
20677 which is the absolute maximum length we can support.

20758 (Make_Subtype_From_Expr): If type has unknown discriminants, always use
20759 base type to create anonymous subtype, because entity may be a locally
20760 declared subtype or generic actual.
20761 (Find_Interface): New subprogram that given a tagged type and one of its
20762 component associated with the secondary table of an abstract interface
20763 type, return the entity associated with such abstract interface type.
20765 * sem_res.adb (Resolve_Type_Conversion): Handle the case in which the
20766 conversion cannot be handled at compile time. In this case we pass this
20767 information to the expander to generate the appropriate code.

20804 (Analyze_Component_Declaration): A limited component is
20805 legal within a protected type that implements an interface.
20806 (Collect_Interfaces): Do not add to the list the interfaces that
20807 are implemented by the ancestors.
20808 (Derived_Type_Declaration): If the parent of the full-view is an
20809 interface perform a transformation of the tree to ensure that it has
20810 the same parent than the partial-view. This simplifies the job of the
20811 expander in order to generate the correct object layout, and it is
20812 needed because the list of interfaces of the full-view can be given in
20814 (Process_Full_View): The parent of the full-view does not need to be
20815 a descendant of the parent of the partial view if both parents are
20817 (Analyze_Private_Extension_Declaration): If declaration has an explicit
20818 "limited" the parent must be a limited type.

20832 (Process_Full_View): Improve the check for the "no hidden interface"
20833 rule as defined by AI-396.
20835 2005-12-09 Robert Dewar <dewar@adacore.com>

20892 available user-specified stream attributes on limited parameters to
20893 also test the type directly rather than only its underlying type (for
20894 Ada 95) and, in the case of Ada 2005, to check that the user-specified
20895 attributes are visible at the point of the subprogram declaration.
20896 For Ada 2005, the error message is modified to indicate that the
20897 type's stream attributes must be visible (again, only for -gnat05).

21059 * socket.c: Add extern int h_errno for rtems since networking header
21060 files are not available at this point in a tool bootstrap. Newlib

21156 may be platform-defined macros.
21157 For VxWorks, generate the OK and ERROR values.
21158 New constants giving the sizes of the components of C struct timeval.

21164 * types.ads: Include All_Checks in Suppress_Array
21166 * checks.adb (Check_Needed): Remove kludge for a/=b rewritten as

21170 deal with different cases of static and dynamic elaboration checks (all
21171 checks does not count in the first case, but does in the second).

21175 in a universal or fixed context
21177 * exp_ch4.adb (Expand_N_Op_Ne): Don't expand a/=b to not(a=b) for
21178 elementary types using the operator in standard. It is cleaner not to
21179 modify the programmers intent, especially in the case of floating-point.
21180 (Rewrite_Comparison): Fix handling of /= (this was always wrong, but
21181 it did not matter because we always rewrote a/=b to not(a=b).
21182 (Expand_Allocator_Expression): For an allocator expression whose nominal
21183 subtype is an unconstrained packed type, convert the expression to its
21184 actual constrained subtype.
21185 Implement warning for <= or >= where < or > not possible
21186 Fix to Vax_Float tests (too early in many routines, causing premature
21187 Vax_Float expansions.

21193 of pragma Suppress (All_Checks)
21194 (Analyze_Pragma, case Warnings): Implement first argument allowed to be
21195 a string literal for precise control over warnings.
21196 Avoid raise of pragma in case of unrecognized pragma and just return

21336 we are not defining the type.
21337 <E_Record_Type>: Likewise.
21338 (gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
21339 to get advantage of the new maybe_stabilize_reference interface, to
21340 ensure that what we reference is indeed stabilized instead of relying
21341 on assumptions on what the stabilizer does.
21342 (gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
21343 type imported through a limited_with clause, use its non-limited view.
21344 (Has_Stdcall_Convention): New macro, to centralize the Windows vs others

21347 of #if sections + explicit comparisons of convention identifiers.

21349 before early-returning for certain types when code generation is
21351 (gnat_to_gnu_entity) <object>: Adjust comment attached to the

21353 that we are not defining.
21354 (elaborate_expression_1): Do not create constants when creating
21355 variables needed by the debug info: the dwarf2 writer considers that
21356 CONST_DECLs is used only to represent enumeration constants, and emits
21358 (gnat_to_gnu_entity) <object>: When turning a non-definition of an
21359 object with an address clause into an indirect reference, drop the
21360 initializing expression.
21362 (STACK_CHECK_BUILTIN): Delete.

21372 subtype to build an actual type with bounds template.
21373 (tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
21374 is provided by the front-end, use that subtype to compute the size of
21375 the deallocated object.

21377 check for a potential violation of a No_Elaboration_Code restriction.

21382 maybe_stabilize, for common uses without restriction on lvalues and
21383 without need to check for the success indication.
21384 (gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
21385 pass false instead of 0 as the FORCE argument which is a bool.
21386 (Identifier_to_gnu): Remove checks ensuring that an renamed object
21387 attached to a renaming pointer has been properly stabilized, as no such
21388 object is attached otherwise.
21389 (call_to_gnu): Invoke create_var_decl to create the temporary when the
21390 function uses the "target pointer" return mechanism.
21391 Reinstate conversion of the actual to the type of the formal
21392 parameter before any other specific treatment based on the passing

21402 * utils2.c (gnat_build_constructor): Only sort the fields for possible
21403 static output of record constructor if all the components are constant.
21404 (gnat_build_constructor): For a record type, sort the list of field
21405 initializers in increasing bit position order.
21406 Factor common code to build a storage type for an unconstrained object
21407 from a fat or thin pointer type and a constrained object type.
21408 (build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
21409 types variants, and process special cases of VIEW_CONVERT expressions

21411 CORRESPONDING_VARs associated with CONST_DECls.
21412 (build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
21413 on the right-hand side.

21420 extracting the object if converting to a type variant.
21421 (create_var_decl): When a variable has an initializer requiring code
21422 generation and we are at the top level, check for a potential violation
21423 of a No_Elaboration_Code restriction.
21424 (create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN

21430 (convert) <VIEW_CONVERT_EXPR>: When the types have the same
21431 main variant, just replace the VIEW_CONVERT_EXPR.

21981 In addition some minor reorganization of the code has been done to
21982 leave it more clear.
21983 (Analyze_Type_Declaration): If type has previous incomplete tagged
21984 partial view, inherit properly its primitive operations.

22026 package associated with a generic instance or formal package, the
22027 private declarations of the parent must be installed (by calling new

22040 whose default is abstract because the object type itself is abstract.
22041 (Find_Type): If the type is incomplete and appears as the prefix of a
22042 'Class reference, it is tagged, and its list of primitive operations
22043 must be initialized properly.
22044 (Chain_Use_Clauses): When chaining the use clauses that appear in the
22045 private declaration of a parent unit, prior to compiling the private
22046 part of a child unit, find on the scope stack the proper parent entity
22047 on which to link the use clause.

22071 remove address operations.
22072 (Check_Infinite_Recursion): Skip freeze nodes when looking for a raise
22073 statement to inhibit warning.
22074 (Resolve_Unary_Op): Do not produce a warning when
22075 processing an expression of the form -(A mod B)
22076 Use Universal_Real instead of Long_Long_Float when we need a high

23118 position set is provided, we compute one in order to reduce the maximum
23119 length of the keys. This computation first selects a character
23120 position between 1 and the minimum length of the keys in order to
23121 avoid reducing one of the keys to an empty string.
23122 (Initialize, Compute): When the ratio V to K is too low, the algorithm
23123 does not converge. The initialization procedure now comes with a

23245 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not add the object
23246 directories of projects that have no Ada sources.
23248 2005-09-01 Robert Dewar <dewar@adacore.com>
23250 * scng.adb (Check_End_Of_Line): Count characters, rather than bytes
23251 (makes a difference for wide characters)
23253 * widechar.adb, widechar.ads:
23254 Add Wide_Char_Byte_Count feature to count chars vs bytes

23257 Ed Schonberg <schonberg@adacore.com>
23258 Robert Dewar <dewar@adacore.com>
23260 * sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
23261 'Address attribute reference with an overloaded prefix, use the
23262 location of the prefix (not the location of the attribute reference) as
23263 the error location.
23264 (Analyze_Attribute, case 'Size): The name of an enumeration literal, or
23265 a function renaming thereof, is a valid prefix for 'Size (where it is
23266 intepreted as a function call).
23267 (Statically_Denotes_Entity): New predicate to determine whether the
23268 prefix of an array attribute can be considered static.
23271 (Eval_Attr): Fix failure to evaluate Component_Size for
23272 unconstrained arrays (resulted in wrong value in packed case, since
23273 back end cannot handle this case)
23275 2005-09-01 Robert Dewar <dewar@adacore.com>
23277 * sem_cat.adb (Check_Categorization_Dependencies): Add more detail to
23278 error msgs for most common cases.
23279 Use new errout insertion char < (conditional warning)
23281 2005-09-01 Javier Miranda <miranda@adacore.com>
23282 Ed Schonberg <schonberg@adacore.com>
23284 * sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
23285 become local to the whole package.
23286 (Install_Limited_Withed_Unit): Instead of unchaining real entities if
23287 the package was already analyzed the new algorithm "replaces" the
23288 real entities by the shadow ones. This is required to ensure that
23289 the order of these entities in the homonym chains does not change;
23290 otherwise we can have undefined references at linking time because
23291 in case of conflicts the external name of the entities will have
23292 a suffix that depends on the order of the entities in the chain.
23293 (Remove_Limited_With_Clause): Complementary code that completes the
23294 new algorithm and replaces the shadow entities by the real ones.
23295 (Install_Limited_Withed_Unit): When unchaining entities before the
23296 installation of the shadow entities, only regular entities of the
23297 public part must be taken into account. This is required to
23298 keep this routine in synch with the work done by Remove_Limited_
23300 (Install_Limited_With_Clause): Introduce implicit limited_with_clause
23301 even if unit is analyzed, because the analysis of the unit is
23302 idempotent in any case, and the limited view of the unit may have to
23303 be installed for proper visibility.
23304 (Expand_Limited_With_Clause): Even if the unit in the implicit
23305 with_clause has been analyzed already, a limited view of the package
23306 must be built for the current context, if it does not exist yet.

23309 Javier Miranda <miranda@adacore.com>
23310 Gary Dismukes <dismukes@adacore.com>
23312 * sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
23313 defining entity for the instance body, make a new defining identifier
23314 rather than copying the entity of the spec, to prevent accidental
23315 sharing of the entity list.
23316 (Check_Private_View): When exchanging views of private types, build the
23317 list of exchanged views as a stack, to ensure that on exit the exchanges
23318 are undone in the proper order.
23319 (Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
23320 Restore the compilation environment in case of instantiation_error.
23321 (Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
23322 for an anonymous access result.
23323 (Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition
23324 (Formal_Entity): Handle properly the case of a formal package that
23325 denotes a generic package renaming.
23327 2005-09-01 Thomas Quinot <quinot@adacore.com>
23329 * sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Reject the
23330 clause if the array aggregate is surrounded by parentheses.
23332 2005-09-01 Cyrille Comar <comar@adacore.com>
23333 Gary Dismukes <dismukes@adacore.com>
23334 Ed Schonberg <schonberg@adacore.com>
23335 Javier Miranda <miranda@adacore.com>
23337 * sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
23339 to check if a type is Constrained in cases related to code generation
23340 (rather than semantic checking) since otherwise we do not generate
23341 similar code for mutable private types depending if their
23342 discriminants are visible or not.
23343 (Check_Abstract_Overriding): Do not complain about failure to override
23344 the primitive operations used in dispatching selects since they will
23345 always be overriden at the freeze point of the type.
23346 (Access_Definition): Separate out handling for resetting the scope
23347 of an anonymous access function result type. Retrieve the scope
23348 of the associated function rather than using Current_Scope, which
23349 does not have a consistent value (depends on whether we're in the
23350 middle of analyzing formal parameters). Add ??? comment about
23351 finding a cleaner way to handle the special cases of scope setting.
23352 (Process_Incomplete_Dependents): A protected operation is never a
23353 dispatching operation (only its wrapper may be).
23354 (Build_Derived_Record_Type): In case of tagged private types that
23355 implement interfaces add derivation of predefined primitive
23357 (Derive_Subprograms): Replace the Is_Interface_Derivation parameter
23358 by two parameters that are used in case of derivation from abstract
23359 interface types: No_Predefined_Prims is used to avoid the derivation
23360 of predefined primitives from the interface, and Predefined
23361 Prims_Only is used to complete the derivation predefined primitives
23362 in case of private tagged types implementing interfaces.
23363 Fix typo in comments
23364 (Find_Interface_In_Descendant): Protect the frontend against
23365 wrong code with large circularity chains.
23366 (Is_Private_Overriding): Add support for entities overriding interface
23367 subprograms. The test failed because Entities associated with overriden
23368 interface subprograms are always marked as hidden (and used to build
23369 the secondary dispatch table); in this case the overriden entity is
23370 available through the field abstract_interface_alias (cf. override_
23371 dispatching_operation)
23372 (Access_Definition): Set the scope of the type to Current_Scope for the
23373 case of a function with an anonymous access result type.
23374 (Access_Subprogram_Declaration): Handle creation of the type entity for
23375 an access-to-function type with an anonymous access result.
23376 (Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
23377 in handling for N_Access_Function_Definition.
23378 (Analyze_Subtype_Declaration): Modify the text of error message.
23379 (Derived_Type_Declaration): Modify the text of error message.
23380 (Process_Subtype): Modify the text of error message plus cleanup
23381 of one redundant error message.
23382 (Analyze_Component_Declaration): Code cleanup.
23383 (Analyze_Object_Declaration): Code cleanup.
23384 (Analyze_Subtype_Declaration): Propagate the null-exclusion
23385 attribute in case of access types. Code cleanup.
23386 (Array_Type_Declaration): Code cleanup.
23387 (Process_Discriminants): Create the new null-excluding itype
23388 if required. Code cleanup.
23389 (Process_Subtype): Create the new null-excluding itype if
23390 required. Code cleanup.
23391 (Build_Derived_Record_Type): Code cleanup to avoid calling
23392 twice the subprogram derive_subprograms in case of private
23393 types that implement interfaces. In this particular case the
23394 subprogram Complete_Subprograms_Derivation already does the
23395 job associated with the second call.
23397 * exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
23398 conversion to the full view when generating an operation for a
23399 discriminant whose type may currently be private.
23401 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23402 Javier Miranda <miranda@adacore.com>
23404 * sem_ch4.adb (Transform_Object_Operation): In a context off the form
23405 V (Obj.F), the rewriting does not involve the indexed component, but
23406 only the selected component itself.
23407 Do not apply the transformation if the analyzed node is an actual of a
23408 call to another subprogram.
23409 (Complete_Object_Operation): Retain the entity of the
23410 dispatching operation in the selector of the rewritten node. The
23411 entity will be used in the expansion of dispatching selects.
23412 (Analyze_One_Call): Improve location of the error message associated
23414 (Analyze_Selected_Component): No need to resolve prefix when it is a
23415 function call, resolution is done when parent node is resolved, as
23417 (Analyze_One_Call): Add a flag to suppress analysis of the first actual,
23418 when attempting to resolve a call transformed from its object notation.
23419 (Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
23420 of the argument list for each interpretation of the operation.
23421 (Try_Object_Operation): The designated type of an access parameter may
23422 be an incomplete type obtained through a limited_with clause, in which
23423 case the primitive operations of the type are retrieved from its full
23425 (Analyze_Call): If this is an indirect call, and the return type of the
23426 access_to_subprogram is incomplete, use its full view if available.
23428 2005-09-01 Javier Miranda <miranda@adacore.com>
23429 Gary Dismukes <dismukes@adacore.com>
23431 * sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
23432 access types the null-exclusion and access-to-constant attributes must
23434 (Analyze_Return_Statement): When the result type is an anonymous access
23435 type, apply a conversion of the return expression to the access type
23436 to ensure that appropriate accessibility checks are performed.
23437 (Analyze_Return_Type): For the case of an anonymous access result type,
23438 generate the Itype and set Is_Local_Anonymous_Access on the type.
23439 Add ??? placeholder for check to disallow returning a limited object
23440 in Ada 2005 unless it's an aggregate or a result of a function call.
23441 Change calls from Subtype_Mark to Result_Definition.
23442 (Analyze_Subprogram_Body): Change formal Subtype_Mark to
23443 Result_Definition in call to Make_Function_Specification.
23444 (Build_Body_To_Inline): Change Set_Subtype_Mark to
23445 Set_Result_Definition.
23446 (Make_Inequality_Operator): Change formal Subtype_Mark to
23447 Result_Definition in call to Make_Function_Specification.
23448 (Process_Formals): Create the new null-excluding itype if required.
23449 (New_Overloaded_Entity): For an entity overriding an interface primitive
23450 check if the entity also covers other abstract subprograms in the same
23451 scope. This is required to handle the general case, that is, overriding
23452 other interface primitives and overriding abstract subprograms inherited
23453 from some abstract ancestor type.
23454 (New_Overloaded_Entity): For an overriding entity that comes from
23455 source, note the operation that it overrides.
23456 (Check_Conformance, Type_Conformant): Addition of one new formal
23457 to skip controlling formals in the analysis. This is used to
23458 handle overloading of abstract interfaces.
23459 (Base_Types_Match): Add missing case for types imported from
23460 limited-with clauses
23461 (New_Overloaded_Entity): Add barrier to protect the use of
23462 the "alias" attribute.
23464 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23466 * sem_ch8.adb (Analyze_Renamed_Entry): For a renaming_as_declaration,
23467 verify that the procedure and the entry are mode conformant.
23468 (Analyze_Subprogram_Renaming): Emit a warning if an operator is renamed
23469 as a different operator, which is often a cut-and-paste error.
23471 2005-09-01 Javier Miranda <miranda@adacore.com>
23472 Ed Schonberg <schonberg@adacore.com>
23474 * sem_disp.adb (Check_Controlling_Formals): Anonymous access types
23475 used in controlling parameters exclude null because it is necessary to
23476 read the tag to dispatch, and null has no tag.
23477 (Override_Dispatching_Operation): If the previous operation is inherited
23478 from an interface, it becomes hidden and does not participate in later
23481 2005-09-01 Javier Miranda <miranda@adacore.com>
23482 Ed Schonberg <schonberg@adacore.com>
23483 Gary Dismukes <dismukes@adacore.com>
23485 * sem_res.adb (Resolve_Membership_Op): In case of the membership test
23486 "Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
23487 the expander will generate the corresponding run-time check to evaluate
23489 (Resolve_Call): Check for legal type of procedure name or prefix that
23490 appears as a trigger in a triggering alternative.
23491 (Valid_Conversion): If expression is ambiguous and the context involves
23492 an extension of System, remove System.Address interpretations.
23493 (Resolve_Qualified_Expression): Reject the case of a specific-type
23494 qualification applied to a class-wide argument. Enhance comment
23495 to explain checking of Original_Node.
23496 (Resolve_Type_Conversion): The location of the error message was not
23497 general enough to handle the general case and hence it has been removed.
23498 In addition, this patch improves the text of the message.
23499 (Resolve_Type_Conversion): Add missing support for access to interface
23501 (Resolve_Type_Conversion): If the target is a class-wide interface type,
23502 do not expand if the expression is the actual in a call, because proper
23503 expansion will take place when the call itself is expanded.
23504 (Resolve_Allocator): If the context is an unchecked conversion, the
23505 allocator inherits its storage pool, if any, from the target type of
23508 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23509 Javier Miranda <miranda@adacore.com>
23511 * sem_type.adb (Add_One_Interp): If a candidate operation is an
23512 inherited interface operation that has an implementation, use the
23513 implementation to avoid spurious ambiguities.
23514 (Interface_Present_In_Ancestor): In case of concurrent types we can't
23515 use the Corresponding_Record_Typ attribute to look for the interface
23516 because it is set by the expander (and hence it is not always
23517 available). For this reason we traverse the list of interfaces
23518 (available in the parent of the concurrent type).
23519 (Interface_Present_In_Ancestor): Handle entities from the limited view
23521 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23523 * sem_util.ads, sem_util.adb (Gather_Components): Omit interface tags
23524 from the list of required components.
23525 (Is_Controlling_Limited_Procedure): Determine whether an entity is a
23526 primitive procedure of a limited interface with a controlling first
23528 (Is_Renamed_Entry): Determine whether an entry is a procedure renaming
23530 (Safe_To_Capture_Value): A value (such as non_null) is not safe to
23531 capture if it is generated in the second operand of a short-circuit
23533 Do not capture values for variables with address clauses.
23534 (Is_Object_Reference): Treat a function call as an object reference only
23535 if its type is not Standard_Void_Type.
23537 2005-09-01 Ed Schonberg <schonberg@adacore.com>
23539 * sem_warn.adb (Warn_On_Known_Condition): Refine warning when applied
23540 to a variable that is statically known to be constant.

23543 Robert Dewar <dewar@adacore.com>

23552 Document that bounds of result of Base_Name match the input index
23554 Add documentation on environment variable syntax for Expand_Path
23556 * gnat_ugn.texi: Update documentation to include mention of -m switches
23557 Document new treatment of wide characters in max line length
23559 Remove -gnatL/-gnatZ switches, no longer used.
23560 Add note on pragmas Assertion_Policy and Debug_Policy in discussion
23563 * gnat_rm.texi: Add doc for two argument form of pragma
23564 Float_Representation.
23565 Add documentation for pragma No_Strict_Aliasing
23566 Add note that explicit component clause overrides pragma Pack.

24322 * a-sytaco.ads, a-sytaco.adb (Suspension_Object): These objects are no
24323 longer protected objects. They have been replaced by lower-level
24324 suspension objects made up by a mutex and a condition variable (or
24325 their equivalent given a particular OS) plus some internal data to
24326 reflect the state of the suspension object.
24327 (Initialize, Finalize): Add this initialization procedure for
24328 Suspension_Object, which is a controlled type.
24329 (Finalize): Add the finalization procedure for Suspension_Object,
24330 which is a controlled type.
24332 * a-sytaco-vxworks.ads, a-sytaco-vxworks.adb: Remove this version of
24333 Ada.Synchronous_Task_Control because there is no longer a need for a
24334 VxWorks specific version of this package. Target dependencies
24335 has been moved to System.Task_Primitives.Operations.
24337 * s-osinte-mingw.ads (pCRITICAL_SECTION): Remove this type which is no
24339 (InitializeCriticalSection, EnterCriticalSection,
24340 LeaveCriticalSection, DeleteCriticalSection): Replace the type
24341 pCriticalSection by an anonymous access type so that we avoid problems
24342 of accessibility to local objects.

24348 s-taprop-tru64.adb, s-taprop-lynxos.adb (Elaboration Code): No longer
24349 set the environment task mask here.
24350 (Current_State): Add this function that returns the state of the
24352 (Set_False): Add this procedure that sets the state of the suspension
24354 (Set_True): Add this procedure that sets the state of the suspension
24355 object to True, releasing the task that was suspended, if any.
24356 (Suspend_Until_True): Add this procedure that blocks the calling task
24357 until the state of the object is True. Program_Error is raised if
24358 another task is already waiting on that suspension object.
24359 (Initialize): Add this procedure for initializing the suspension
24360 object. It initializes the mutex and the condition variable which are
24361 used for synchronization and queuing, and it sets the internal state
24363 (Finalize): Add this procedure for finalizing the suspension object,
24364 destroying the mutex and the condition variable.

24369 s-taspri-tru64.ads, s-taspri-lynxos.ads (Suspension_Object): New object
24370 which provides a low-level abstraction (using operating system
24371 primitives) for Ada.Synchronous_Task_Control.
24372 This object is made up by a mutex (for ensuring mutual exclusion), a
24373 condition variable (for queuing threads until the condition is
24374 signaled), a Boolean (State) indicating whether the object is open,
24375 and a Boolean (Waiting) reflecting whether there is a task already
24376 suspended on this object.

24384 (Setup_Interrupt_Mask): New procedure.
24386 * s-intman-vxworks.ads, s-intman-vxworks.adb: Update comments.
24388 * s-inmaop.ads (Setup_Interrupt_Mask): New procedure
24390 * s-interr.adb: Add explicit call to Setup_Interrupt_Mask now that
24391 this is no longer done in the body of s-taprop
24392 (Server_Task): Explicitely test for Pending_Action in case
24393 System.Parameters.No_Abort is True.
24395 * s-taasde.adb: Add explicit call to Setup_Interrupt_Mask now that this
24396 is no longer done in the body of s-taprop

24641 type derivation of private tagged types implementing interfaces.
24642 In this case some interface primitives may have been overriden

24732 * i-cpp.ads, i-cpp.adb:
24733 This package has been left available for compatibility with previous
24734 versions of the frontend. As part of the new layout this is now a

24788 access to subprograms must be recursive.
24789 (Is_Unchecked_Conversion): Improve the test that recognizes
24790 instantiations of Unchecked_Conversion, and allows them in bodies that
24791 are to be inlined by the front-end. When the body comes from an

24814 object or component (that is, when Is_Local_Anonymous_Access is true).
24815 Prevent the special checks for conversions of access discriminants in
24816 the case where the discriminant belongs to a nonlimited type, since
24817 such discriminants have their accessibility level defined in the same
24818 way as a normal component of an anonymous access type.
24819 (Resolve_Allocator): When an allocator's designated type is a class-wide
24820 type, check that the accessibility level of type given in the
24821 allocator's expression or subtype indication is not statically deeper

24838 pragma Restrictions (No_Obsolescent_Features).
24839 (Check_Direct_Boolean_Operator): If the boolean operation has been
24840 constant-folded, there is nothing to check.
24841 (Resolve_Comparison_Op, Resolve_Equality_Op, Resolve_Boolean_Op): Defer
24842 check on possible violation of restriction No_Direct_Boolean_Operators
24843 until after expansion of operands, to prevent spurious errors when

24878 (Apply_Float_Conversion_Check): Generate a short-circuit expression for
24879 both bound checks, rather than a conjunction.
24880 (Insert_Valid_Check): If the expression is an actual that is an indexed

25035 non-overloaded intrinsic subprogram.
25036 (Check_Stream_Attribute): Reject an attribute reference for an

25146 the "simple_choice" member in a variant record, in accordance with the
25147 description in the package spec: the information output for a constant
25148 should be "S number", not "SS number".
25149 (Get_Encoded_Name): Return at once if not generating code. Avoids name

25266 (Get_Type_Reference): For a subtype that is the renaming of an actual in
25267 an instantiation, use the first_subtype to ensure that we don't generate

25299 different contents.
25300 (__gnat_adjust_context_for_raise) i386-linux: First version of this
25301 function for this target. Adjust PC by one in the machine context. This
25302 adjustment was previously done in the MD_FALLBACK_FRAME_STATE_FOR, but
25303 it is more reliable to do that in the signal handler itself.
25304 (__gnat_install_handler) i386-linux: Set SA_SIGINFO in the sigaction

25306 prior to the raise.
25307 (__gnat_error_handler) i386-linux: Adjust the signature to match what a
25308 SA_SIGINFO sigaction should look like. Call

25853 (unrelated) errors).
25855 * sem_prag.adb (Analyze_Pragma, case Asynchronous): If RAS expansion
25856 is disabled, the entity denoted by the argument is the access type

25890 a class-wide stream attribute) and then rewrite the attribute name
25891 as the name of the appropriate compiler-generated stream primitive.

25942 (Recursive_Process): Set Display_Name equal to Name
25943 when Location is No_Location, that is when there is no actual file.

25975 references to protected formals, among others.
25976 (Analyze_Explicit_Dereference): If the overloaded prefix includes some
25977 interpretation that can be a call, include the result of the call as a
25978 possible interpretation of the dereference.
25980 * sem_ch5.adb (Process_Bounds): Determine type of range by
25981 pre-analyzing a copy of the original range, and then analyze the range
25982 with the expected type.
25984 * sem_res.adb (Check_Parameterless_Call): For an explicit dereference

25988 the node as a call once the context identifies the interpretation of
25989 the prefix whose call yields the context type.
25990 (Valid_Conversion): For the case of a conversion between
25991 local access-to-subprogram types, check subtype conformance using
25992 Check_Subtype_Conformant instead of Subtype_Conformant, to have a more

26668 These subprogram have been removed because the attribute
26669 Task_Body_Procedure has been moved to the corresponding task type
26670 or task subtype entity to leave a field free to store the list
26671 of interfaces implemented by a task (for AI-345)

26788 it is one or is derived from one, or because its completion is derived
26790 (Constrain_Component_Type): If component comes from source and has no
26791 explicit constraint, no need to constrain in in a subtype of the

26815 * exp_pakd.adb (Create_Packed_Array_Type): Do not set
26816 Must_Be_Byte_Aligned for cases where we do not need to use a
26817 System.Pack_nn unit.
26819 * exp_ch6.adb (Expand_Call): Call Expand_Actuals for functions as well
26821 Needed now that we do some processing for IN parameters as well. This
26822 may well fix some unrelated errors.
26823 (Expand_Call): Handle case of unaligned objects (in particular those
26824 that come from packed arrays).
26825 (Expand_Inlined_Call): If the subprogram is a renaming as body, and the
26826 renamed entity is an inherited operation, re-expand the call using the
26827 original operation, which is the one to call.
26828 Detect attempt to inline parameterless recursive subprogram.
26829 (Represented_As_Scalar): Fix to work properly with private types
26830 (Is_Possibly_Unaligned_Object): Major rewrite to get a much more
26831 accurate estimate. Yields True in far fewer cases than before,
26832 improving the quality of code that depends on this test.
26834 * exp_util.adb (Kill_Dead_Code): For a package declaration, iterate
26835 over both visible and private declarations to remove them from tree,
26836 and mark subprograms declared in package as eliminated, to prevent
26837 spurious use in subsequent compilation of generic units in the context.
26839 * exp_util.ads: Minor cleanup in variable names
26841 * sem_eval.ads, sem_eval.adb: Minor reformatting
26842 (Compile_Time_Known_Bounds): New function
26844 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26846 * exp_ch7.adb (Convert_View): Use base types of underlying types when
26847 determining whether an unchecked conversion is needed for the argument
26848 of an initialization call.
26850 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26852 * exp_intr.adb (Expand_Unc_Conversion): As a target type, use the type
26853 that appears in the instantiation rather than the internal subtype
26854 generated in the wrapper package, to avoid anomalies in gigi when the
26855 target is derived from a private type whose full view is an access type.
26857 2005-03-15 Robert Dewar <dewar@adacore.com>
26859 * exp_smem.adb, sem_attr.adb: Remove OK_For_Stream flag, not used,
26861 Add documentation to replace the use of this flag
26862 Fix kludge for Maximum_Alignment on x86 so that it does not apply to
26865 2005-03-15 Thomas Quinot <quinot@adacore.com>
26867 * exp_tss.ads, exp_tss.adb (Find_Inherited_TSS): New subprogram, moved
26868 here from exp_attr so it can be shared between exp_attr and exp_dist.
26869 (TSS_Names): Renamed from OK_TSS_Names. This array contains the list of
26870 all TSS names, not a subset thereof, and the previous name introduced
26871 an unnecessarily confusion that a distinction might exist between
26872 "OK" TSS names and some "not OK" TSS names.
26874 2005-03-15 Doug Rupp <rupp@adacore.com>
26876 * gnatchop.adb (Locate_Executable): Normalize the possibly VMS style
26879 2005-03-15 Pascal Obry <obry@adacore.com>
26880 Eric Botcazou <ebotcazou@adacore.com>
26884 * init.c (__gnat_initialize): Do not call __gnat_install_SEH_handler()
26885 when IN_RTS. This is to work around a bootstrap path problem.
26887 * misc.c (gnat_parse_file): Create a SEH (Structured Exception Handler)
26888 table and pass it to __gnat_install_SEH_handler().
26889 (gnat_handle_option): Accept OPT_fRTS_, not OPT_fRTS.
26891 * lang.opt: Fix specification of -fRTS=.
26893 2005-03-15 Doug Rupp <rupp@adacore.com>
26894 Bernard Banner <banner@adacore.com>
26895 Vincent Celier <celier@adacore.com>
26896 Arnaud Charlet <charlet@adacore.com>
26899 This change works fine when gnatlib is built from the gcc directory,
26900 but does not work when using the libada Makefile, since GCC_FOR_TARGET
26901 is not passed to ada/Makefile.in, so more work is needed by a
26902 Makefile/configure expert.
26904 * Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
26905 set GMEM_LIB on ia64 linux to add optional support for gnatmem.
26906 Setup gnatlink switch -M for x86_64 linux, as it is already setup
26908 (gnatlib-shared-default): Use GNATLIBCFLAGS as well.
26909 Run ranlib on libgccprefix.a
26910 Define PREFIX_OBJS for Darwin, to build libgccprefix.
26911 (ADA_INCLUDE_SRCS): Split Ada packages.
26913 2005-03-15 Robert Dewar <dewar@adacore.com>
26915 * Make-lang.in: Add g-utf_32 unit for gnat and gnatbind
26917 * impunit.adb: Add GNAT.UTF_32
26919 * scng.adb: Use gnat.utf_32 instead of widechar for utf_32 stuff
26921 * widechar.ads, widechar.adb: Remove redundant UTF-32 tables (scng
26922 now uses GNAT.UTF_32).
26924 * g-utf_32.ads, g-utf_32.adb: This is a new unit with full
26925 capabilities for categorizing characters using Unicode categories
26927 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26929 * sem_ch10.adb (Build_Ancestor_Name): If the ancestor is an
26930 instantiation that has been rewritten as a package body, retrieve spec
26931 to generate proper name for implicit_with_clause.
26932 (Install_Parents): Recognize a parent that is an instantiation but has
26933 been rewritten as a package declaration during analysis.
26935 2005-03-15 Javier Miranda <miranda@adacore.com>
26936 Ed Schonberg <schonberg@adacore.com>
26938 * sem_ch12.adb (Instantiate_Object): If the analysis of the actual
26939 parameter reported some error we immediately return. This improves the
26940 behaviour of the frontend in case of errors.
26941 (Install_Parent, Remove_Parent): Introduce new flag
26942 Parent_Unit_Visible, to preserve the proper visibility of the ultimate
26943 ancestor of a generic child unit, when the child is being instantiated.
26944 (Inline_Instance_Body): If we are compiling the private
26945 part or the body of a child unit, restore the proper visibility of the
26946 parents after compiling the instance body.
26948 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26949 Javier Miranda <miranda@adacore.com>
26952 * sem_util.adb (Get_Task_Body_Procedure): Type may be the completion
26953 of a private type, in which case it is underlying_type that denotes
26954 the proper task. Also modified to use the new entity attribute
26955 that is directly available in the task type and task subtype entities
26956 (Build_Actual_Subtype_Of_Component): Handle properly multidimensional
26957 arrays when other dimensions than the first are constrained by
26958 discriminants of an enclosing record.
26959 (Insert_Explicit_Dereference): If the prefix is an indexed component or
26960 a combination of indexed and selected components, find ultimate entity
26961 and generate the appropriate reference for it, to suppress spurious
26963 (Note_Possible_Modification): If an entity name has no entity, return.
26964 (Is_Variable): A function call never denotes a variable.
26965 (Requires_Transient_Scope): For record types, recurse only on
26966 components, not on internal subtypes that may have been generated for
26967 constrained components.
26969 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26971 * sem_ch4.adb (Analyze_Concatenation): Do not consider operators marked
26972 Eliminated as candidates for resolution. Both efficient, and avoids
26973 anomalies with operators declared in deleted code.
26974 (Process_Implicit_Dereference_Prefix): Use this procedure whenever
26975 expansion is disabled (as when compiling a generic) to prevent spurious
26976 warnings on prefixes of selected components.
26978 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26980 * sem_ch6.adb (Is_Private_Declaration): Verify that the declaration is
26981 attached to a list before checking whether it appears in the private
26982 declarations of the current package.
26983 (Make_Inequality_Operator): Insert declaration in proper declarative
26984 list rather than just setting the Parent field, so that
26985 Is_Private_Declaration can handle it properly.
26987 2005-03-15 Ed Schonberg <schonberg@adacore.com>
26989 * sem_ch8.adb (Analyze_Subprogram_Renaming): In a generic, if this is
26990 a renaming a body, check that the renamed subprogram in not intrinsic.
26991 (Find_Direct_Name): If several use_visible entities hide
26992 each other, and the context is a predefined file compiled through
26993 rtsfind, keep only the entity that comes from a predefined file.
26995 2005-03-15 Geert Bosch <bosch@adacore.com>
26997 * s-fatgen.adb (Valid): Extend special exceptions to account for long
26998 long float padding to also cover AMD64 and IA64.
27000 2005-03-15 Gary Dismukes <dismukes@adacore.com>
27002 * s-imgwch.adb: Add with and use of Interfaces.
27003 (Img_Wide_Character): Change type of Val to Unsigned_16.
27004 (Img_Wide_Wide_Character): Change type of Val to Unsigned_32.
27006 2005-03-15 Matthew Gingell <gingell@adacore.com>

27052 Sergey Rybin <rybin@adacore.com>
27054 * gnat_ugn.texi: Remove extended inline assembly example, as it was far
27055 too specific and long-winded to be appropriate for the GNAT User's

27058 as these may cause generated code to not conform to Ada semantics.
27059 Remove mention of -gdwarf-2 for sparc64, since this is now the default.

27317 new reserved words of Ada 2005: Tok_Interface, Tok_Overriding
27318 and Tok_Synchronized.
27320 * sem_res.adb (Resolve_Actuals): Change error messages to refer to
27321 "dispatching" rather than "primitive" operations, since dispatching

27325 (Resolve_Slice): If the prefix is an access to an unconstrained array,
27326 compute the actual subtype of the designated object to impose the proper
27328 (Resolve_Selected_Component): Do not insert an access check if the
27329 prefix is an access type: such a node is expanded into an explicit
27330 dereference, on which the access check is performed anyway. Removes
27331 expensive duplicate checks.
27332 (Resolve_Call): Use new flag Is_Obsolescent and field
27333 Obsolescent_Warning so that pragma Obsolescent works on library
27335 Add support for wide wide character type
27336 (Resolve_Allocator): Replace the error message on wrong null-exclusion
27337 value by a warning message.
27338 (Resolve_Type_Conversion): If the mixed-mode expression is interpreted
27339 as fixed-point, and one of the operands is non-static and universal, it
27340 can only be an illegal exponentiation operation, in which case there is
27341 no real value to retrieve.
27343 * exp_strm.adb: Add support for wide wide character type
27344 (Build_Elementary_Input_Call): Compute the size of the stream element by

27384 (Unit_Declaration_Node): Ditto.
27385 (Is_Variable_Prefix): For the case of an indexed component whose prefix
27386 has a packed array type, the prefix has been rewritten into a type

27392 * stringt.ads, stringt.adb: Handle full UTF-32 range.
27393 Remove ["0A"] from comment, since it can look like a line terminator.
27394 Currently we don't permit this, but this is under discussion by the
27395 ARG, and it is easy enough to use a different example.
27397 * s-wchcon.ads, s-wchcnv.ads, s-wchcnv.adb: Add new subprograms for
27398 handling UTF-32 encoding for wide wide character.

27417 wrong null-exclusion value by a warning message.
27418 (Enable_Range_Check): Do range check if the prefix is an
27419 explicit dereference whose designated object is an unconstrained array.
27420 Current algorithm for removing duplicate checks is over-eager in this

27456 * i-cpp.ads, i-cpp.adb, a-tags.ads, a-tags.adb: Update documentation
27457 describing the new layout.
27458 (Dispatch_Table): The expander computes the actual array size, allocates
27459 the Dispatch_Table record accordingly, and generates code that displaces
27460 the base of the record after the Typeinfo_Ptr component. The access to
27461 these components is done by means of local functions.
27462 (Offset_To_Top): New function.
27463 (Typeinfo_Ptr): New function.
27464 (Get_TSD): Modified to access the new position of the TSD.

27475 N_Formal_Subtype_Declaration (which is now a subtype).
27476 (Analyze_Formal_Subprogram): Add handling for
27477 N_Formal_Abstract_Subprogram, marking the formal as abstract and
27478 dispatching, setting the controlling status of the formal parameters
27479 and result, and issuing an error if there is no controlling type for
27480 the formal subprogram.
27481 (Instantiate_Formal_Subprogram): Rather than setting Corresponding_Spec,
27482 which is an unclean use of that field, we set the new field
27483 Corresponding_Formal_Spec to make the formal subprogram available to

27491 abstract formal subprograms in error check for functions returning
27492 abstract types. Set scope of new designator for

27495 (Analyze_Subprogram_Body): Warn on inlining bodies with nested
27496 subprogram only if inner one comes from source.
27497 (Analyze_Function_Call): If the call is given in object notation, the
27498 analysis of the name rewrites the node and analyzes it with the proper
27499 argument list. After analyzing the name, if the call has been rewritten
27500 and the result type is set, no further analysis is needed.
27501 (Analyze_Return_Type): Subsidiary to Process_Formals: analyze subtype
27502 mark in function specification, in a context where the formals are
27503 visible and hide outer homographs.
27505 * sem_disp.adb (Check_Controlling_Type): Relax the check for same scope
27506 as the tagged type for the cases of abstract formal subprograms and
27507 renamings of those. Clean up spec comments.
27508 (Check_Dispatching_Context): Add error message to indicate "abstract
27509 procedure", covering the case of a call to a formal abstract procedure
27510 that has statically tagged operands.
27511 (Check_Dispatching_Call): Check for the case of an actual given by
27512 a tag-indeterminate function call whose type is an ancestor of the
27513 containing call's associated tagged type. This situation can occur
27514 for inherited primitives with function defaults. In this case we
27515 use the tagged type's tag directly as the controlling argument for
27517 (Expand_Call): Name change on call to Expand_Dispatch_Call.
27519 * sprint.adb (Sprint_Node_Actual): Split
27520 N_Formal_Subprogram_Declaration into two alternatives for the new

27597 on the field if Pragma Component_Alignment (Storage_Unit).
27598 (gnat_to_gnu_entity, case object): Do not treat a renaming that has
27599 side-effects as if it were a constant; also make SAVE_EXPR to protect

27619 * exp_aggr.adb (Gen_Assign): If the expression is an aggregate for a
27620 component of an array of arrays in an assignment context, and the
27621 aggregate has component associations that require sliding on
27622 assignment, force reanalysis of the aggregate to generate a temporary
27623 before the assignment.
27624 (Must_Slide): Make global to the package, for use in Gen_Assign.
27626 2005-02-09 Ed Schonberg <schonberg@adacore.com>
27628 * exp_ch4.adb (Expand_Composite_Equality): If a component is an
27629 unchecked union with no inferable discriminants, return a
27630 Raise_Program_Error node, rather than inserting it at the point the
27632 (Expand_Record_Equality, Component_Equality): Handle properly the case
27633 where some subcomponent is an unchecked union whose generated equality
27634 code raises program error.

27642 Arnaud Charlet <charlet@adacore.com>
27644 * init.c (__gnat_initialize): Add a new parameter eh which contains the
27645 address of the exception registration. The Win32 version of this
27646 routine calls __gnat_install_SEH_handler() to initialize the SEH
27647 (Structured Exception Handling) handler.
27648 (__gnat_error_handler) [Win32]: Removed. Not needed as we use
27649 SEH (Structured Exception Handling) now.
27650 (__gnat_install_handler) [Win32]: Nothing to do now as we use SEH.
27651 (__gnat_initialize for ppc-vxworks): Adjust comments and the
27652 preprocessor condition protecting the call to the extra eh setup
27653 subprogram, which is only available for the ppc target.

27667 Update copyright notice.
27669 * s-tassta.adb (Task_Wrapper): Declare the exception registration

27699 2005-02-09 Vincent Celier <celier@adacore.com>
27701 * prj-makr.adb (Process_Directory): Put file name in canonical case
27702 before matching against the patterns.
27703 If gnatname has been invoked as <prefix>-gnatname
27704 then invoke the compiler as <prefix>-gcc, not just "gcc".
27706 2005-02-09 Ed Schonberg <schonberg@adacore.com>
27708 * sem_ch4.adb (Analyze_Selected_Component): Create Actual_Subtype even
27709 with expansion disabled. The actual subtype is needed among other
27710 places when the selected component appears in the context of a loop
27711 bound, and denotes a packed array.
27712 (Operator_Check): Always use the first subtype in the
27713 error message, to avoid the appearance of internal base types.
27714 (Transform_Object_Operation): Copy each actual in full
27715 to the parameter associations of the constructed call, rather than
27716 using the shallow copy mechanism of New_Copy_List. This ensures that
27717 the chaining of named associations is done properly.
27718 (Complete_Object_Operation): Rewrite node, rather than
27719 replacing it, so that we can trace back to the original selected
27722 * sem_elab.adb (Set_Elaboration_Constraint): For initialization calls,
27723 and calls that use object notation, if the called function is not
27724 declared in a withed unit, place the elaboration constraint on the
27725 unit in the context that makes the function accessible.
27726 (Check_Elab_Subtype_Declaration): Check whether a subtype declaration
27727 imposes an elaboration constraint between two packages.
27729 2005-02-09 Ed Schonberg <schonberg@adacore.com>
27731 * sem_ch7.adb (Uninstall_Declarations): Exchange full and private
27732 views of a private type after handling its private dependents, to
27733 maintain proper stack discipline between entry and exit from the

27749 recursion warnings when compiled with -gnatdm.
27751 2005-02-09 Robert Dewar <dewar@adacore.com>
27753 * usage.adb: Add line for switch -gnat05 (allow Ada 2005 extensions)
27754 Slight fix to documentation of -gnaty with no parameters
27756 * xr_tabls.ads: Add ??? comment for missing overall comment
27758 * xsinfo.adb: Make default file name be sinfo.h, since this is what
27759 we now use by default.
27761 * xsnames.adb: Adjust end of file test to look for five space followed
27762 by '#' instead of six spaces. The format of xsnames.adb was modified
27763 in the last update.
27765 * a-numeri.ads: Add reference to AI-388 for greek letter pi
27768 * clean.adb: Minor reformatting.
27770 * gnat1drv.adb, gnatfind.adb, gnatlink.adb, gnatmem.adb,
27771 gnatname.adb: Minor reformatting
27772 Add 2005 to copyright output when utility is run
27774 * csets.adb: Eliminate obsolete comment
27776 * debug.adb, g-socket.ads, i-cobol.adb: Minor reformatting throughout
27779 * sem_eval.ads (Eval_Integer_Literal): Do not inline this, not useful.
27781 2005-02-09 Sergey Rybin <rybin@adacore.com>
27783 * gnat_ugn.texi: Add to the gnatpp section the paragraph describing
27784 the difference between compact and incompact layout and add the record
27785 representation clause to the example illustrating different layouts.
27786 Add the description of '-A5' gnatpp option ("align 'AT' keywords in

28094 is to check if two function signatures for a call-site and a callee are
28095 compatible enough for the call to be valid. The underlying purpose is

28150 (Add_Receiving_Stubs_To_Declarations): Make this subprogram
28152 Simplify elaboration code for RCI packages.
28154 * s-parint.ads, s-parint.adb, rtsfind.ads: Reorganise RPC receiver

28264 note that it applies to obsolete GNAT features, which was previously
28265 omitted. Second we contrast the behavior with that of the new
28266 Ada 2005 AI-368 restriction No_Obsolescent_Features.

28487 TYPE_SIZE_UNIT of result type if SIZE is not specified.
28488 (make_aligning_type): Pass -1 as ADDRESSABLE to prevent the creation

28498 (create_field_decl): Special case ADDRESSABLE negative to mean
28499 "no bitfield creation", to be used by make_aligning_type. Don't
28500 restrict bitfield creation to !ADDRESSABLE any more, as some BLKmode
28501 fields claimed addressable still have to be bitfields. Use
28502 value_factor_p instead of a raw binop construction to check for the
28503 position's alignment.
28505 2004-12-07 Geert Bosch <bosch@adacore.com>

28510 Ed Schonberg <schonberg@adacore.com>
28512 * exp_ch4.adb (Expand_N_Indexed_Component): For an indexed component
28513 with an implicit dereference as its prefix, use
28514 Insert_Explicit_Dereference instead of merely rewriting the prefix into
28515 an explicit dereference. This ensures that a reference to the original
28516 prefix is generated, if appropriate.
28518 * sem_util.adb (Insert_Explicit_Dereference): When an implicit
28519 dereference is rewritten to an explicit one, generate a reference to
28520 the entity denoted by its prefix using the original prefix node, so
28521 the dereference can be properly recorded as a read of the denoted
28522 access value, if appropriate.
28524 * sem_warn.adb (Output_Unreferenced_Messages): Do not abstain from
28525 emitting 'assigned but never read' warning on a variable on the basis

28538 This deals with the case where the pragma Import specified
28539 an external name, to be handled by the back end.
28541 * sem_prag.adb (Process_Import_Or_Interface): Do not check validity of
28542 subprogram which is Imported with convention Intrinsic if an
28543 External_Name argument is specified.
28544 (Process_Import_Or_Interface): Properly diagnose link name argument.
28545 (Inlining_Not_Possible): New name for Cannot_Inline, to avoid confusion
28546 with Sem_Ch6.Cannot_Inline.
28547 (Process_Inline): Provide separate warning for inapplicable inline
28549 (Cannot_Inline): Reject subprograms that have an at_end handler, so that
28550 treatment is uniform on different targets.

28567 implementation of the partition communication subsystem in ancillary
28569 (Specific_Build_Stub_Type, GARLIC_Support.Build_Stub_Type,
28570 PolyORB_Support.Build_Stub_Type): New subrograms containing the
28571 PCS-specific part of Add_Stub_Type.
28572 (Insert_Partition_Check): Use runtime library function to perform
28575 * rtsfind.ads: New entity System.PolyORB_Interface.Make_Ref
28576 (RE_Same_Partition): New entity, from s-parint.

28601 * sem_ch9.adb (Analyze_Accept_Statement): Reset the Is_Referenced flag
28602 and the Has_Pragma_Unreferenced flag for each formal before analyzing
28603 the body, to ensure that warnings are properly emitted for each accept
28604 statement of a given task entry.
28606 2004-12-07 Vasiliy Fofanov <fofanov@adacore.com>
28608 * Makefile.in: Add support for foreign threads on VMS.

28626 (Remove_Next_Debug): Same fix
28628 * nlists.ads: Correct bad comments for Prev and Prev_Non_Pragma (we do
28629 maintain back pointers now, though we did not used to, and comments
28631 (Prepend): Remove pragma Inline.
28632 (Remove_Next): Same cleanup
28634 2004-12-07 Thomas Quinot <quinot@adacore.com>
28636 * sem_ch4.adb (Process_Implicit_Dereference_Prefix): New subprogram
28637 used to record an implicit dereference as a read operation on its
28638 prefix when operating under -gnatc. Necessary to avoid spurious
28639 'variable assigned but never read' warnings in that mode.
28640 (Process_Indexed_Component, Analyze_Selected_Component): When the prefix
28641 is a non-overloaded implicit dereference, call the above subprogram to
28642 ensure proper recording of references.
28644 2004-12-07 Gary Dismukes <dismukes@adacore.com>
28646 * sem_ch5.adb (One_Bound): Remove call to Resolve, as the bound needs
28647 to be resolved later as part of Analyze_Iteration_Scheme's call to

28694 2004-12-07 Vincent Celier <celier@adacore.com>
28696 * vms_data.ads: Correct GNAT METRIC qualifiers: -I-, -Idir and
28697 -gnatec= are not direct switches of gnatmetric. Changed -eis to -eps
28698 and -eit to -ept. Added qualifier
28699 /ELEMENT_METRICS=CONSTRUCT_NESTING_MAX for new switch -ec.
28701 2004-11-27 Andreas Schwab <schwab@suse.de>
28703 * Make-lang.in (ada/trans.o): Depend on $(EXPR_H).
28705 2004-11-25 Arnaud Charlet <charlet@adacore.com>
28707 * g-socthi-mingw.ads, g-socthi-vms.ads: Remove C_Read and C_Write from
28708 internal implementation unit GNAT.Sockets.Thin,
28709 as their usage for sockets is non-portable (using the read and write
28710 functions from the system runtime library is fine on UNIX but won't
28711 work under Windows).

28764 (Setup_Exception): Do nothing in the GNAT SJLJ case.
28766 * gigi.h (others_decl, all_others_decl): New decls representing the
28767 new Others_Value and All_Others_Value objects.
28768 (struct attrib): Rename "arg" component as "args", since GCC expects a
28769 list of arguments in there.
28771 * raise.c (GNAT_OTHERS, GNAT_ALL_OTHERS): Are now the address of the
28772 corresponding objects exported by a-exexpr, instead of hardcoded dummy
28775 * trans.c (Exception_Handler_to_gnu_zcx): Use the address of
28776 others_decl and all_others_decl instead of hardcoded dummy addresses
28777 to represent "others" and "all others" choices, which is cleaner and
28778 more flexible with respect to the possible eh pointer encoding policies.
28780 * utils.c (init_gigi_decls): Initialize others_decl and all_others_decl.
28781 (process_attributes): Account for the naming change of the "args"
28782 attribute list entry component.
28784 * decl.c (build_attr_list): Rename into prepend_attributes to allow
28785 cumulating attributes for different entities into a single list.
28786 (gnat_to_gnu_entity): Use prepend_attributes to build the list of
28787 attributes for the current entity and propagate first subtype
28788 attributes to other subtypes.
28789 <E_Procedure>: Attribute arguments are attr->args and not
28790 attr->arg any more.
28791 (build_attr_list): Ditto. Make attr->args a TREE_LIST when there is an
28792 argument provided, as this is what GCC expects. Use NULL_TREE instead
28795 2004-11-18 Robert Dewar <dewar@adacore.com>
28797 * a-stmaco.ads, exp_util.ads, exp_util.adb, i-cpp.ads, i-cpp.adb:
28798 Minor reformatting througout (including new function specs)
28799 Add ??? comments asking for clarification.
28801 2004-11-18 Thomas Quinot <quinot@adacore.com>
28803 * butil.ads, butil.adb, bindgen.adb (Get_Unit_Name_String): Remove
28804 incomplete duplicate implementation of this subprogram from butil.
28806 2004-11-18 Thomas Quinot <quinot@adacore.com>
28808 * exp_dist.adb (Build_RPC_Receiver_Body): New subprogram. This
28809 procedures factors the common processing for building an RPC receiver
28810 for an RCI package or an RACW type.
28811 Stylistic cleanup: change '/= Empty' to 'Present ()'; move body of
28812 Build_Remote_Subprogram_Proxy_Type into proper alphabetical order.
28813 (Get_PCS_Name): New subprogram. Returns the name of the PCS currently
28815 (Specific_Add_RACW_Features): New subprogram. PCS-specific part of
28817 (Specific_Add_RAST_Features): New subprogram. PCS-specific part of
28819 (Assign_Subprogram_Identifier): New subprogram. Provision for assigning
28820 distribution subprogram identifiers that are either subprogram numbers
28822 (Get_Subprogram_Ids): New subprogram. Retrieve both the numeric and
28823 string distribution identifiers assigned to a given subprogram.
28824 (Get_Subprogram_Id): Reimplement in terms of Get_Subprogram_Ids.
28825 (Add_RAS_Dereference_TSS): Add comments.
28826 (Build_General_Calling_Stubs): Note that the RACW_Type formal parameter
28827 is not referenced yet because it will be used by the PolyORB DSA
28829 (Insert_Partition_Check): Remove fossile code.
28830 (First_RCI_Subprogram_Id): Document this constant.
28831 (Add_RAS_Access_TSS): Correct the setting of the Etype of the
28833 (Get_Pkg_Name_String): Remove subprogram. Usage occurrences are
28834 replaced with calls to Get_Library_Unit_Name_String. Previously there
28835 were several instances of the same code in different locations in the
28836 compiler; this checkin completes the replacement of all of these
28837 instances with calls to a common subprogram.
28838 Minor reformatting.
28840 * sem_dist.adb: Remove comment noting that RPC receiver generation
28841 should be disabled for RACWs that implement RASs.
28842 (Process_Partition_Id): Use new subprogram Get_Library_Unit_Name_String.
28844 * sem_util.ads, sem_util.adb (Has_Stream): New function

28846 qualified name of a library unit into the name buffer.
28847 (Note_Possible_Modification): Generate a reference only
28848 if the context comes from source.
28850 * snames.ads (PCS_Names): New subtype corresponding to names of
28851 supported implementations of the Partition Communication Subsystem
28852 (PCS) (i.e. the runtime library support modules for the distributed
28855 2004-11-18 Robert Dewar <dewar@adacore.com>
28856 Ed Schonberg <schonberg@adacore.com>
28858 * einfo.ads, einfo.adb: Remove Is_Psected flag, no longer used
28859 (Has_Rep_Pragma): New function
28860 (Has_Attribute_Definition_Clause): New function
28861 (Record_Rep_Pragma): Moved here from sem_ch13.adb
28862 (Get_Rep_Pragma): Remove junk kludge for Stream_Convert pragma
28864 * sem_ch13.ads, sem_ch13.adb (Record_Rep_Pragma): Moved to einfo.adb
28866 * exp_prag.adb: (Expand_Pragma_Common_Object): New procedure
28867 (Expand_Pragma_Psect_Object): New procedure
28868 These procedures contain the revised and cleaned up processing for
28869 these two pragmas. This processing was formerly in Sem_Prag, but
28870 is more appropriately moved here. The cleanup involves making sure
28871 that the pragmas are properly attached to the tree, and that no
28872 nodes are improperly shared.
28874 * sem_prag.adb: Move expansion of Common_Object and Psect_Object
28875 pragmas to Exp_Prag, which is more appropriate.
28876 Attach these two pragmas to the Rep_Item chain Use Rep_Item chain to
28877 check for duplicates Remove use of Is_Psected flag, no longer needed.
28878 Use new Make_String_Literal function with string.
28880 * exp_attr.adb (Expand_Fpt_Attribute): The floating-point attributes
28881 that are functions return universal values, that have to be converted
28882 to the context type.
28883 Use new Make_String_Literal function with string.
28884 (Get_Stream_Convert_Pragma): New function, replaces the use of
28885 Get_Rep_Pragma, which had to be kludged to work in this case.
28887 * freeze.adb: Use new Has_Rep_Pragma function
28889 * exp_intr.adb, exp_ch3.adb, sem_attr.adb: Use new Make_String_Literal
28890 function with string.
28891 Use new Has_Rep_Pragma function.
28893 * tbuild.ads, tbuild.adb (Make_String_Literal): New function, takes
28896 2004-11-18 Robert Dewar <dewar@adacore.com>
28898 * errout.ads, errout.adb: (First_Sloc): New function
28900 * par-ch5.adb (P_Condition): Check for redundant parens is now a style
28901 check (-gnatyx) instead of being included as a redundant construct
28904 * sem_ch6.adb: Change name Style_Check_Subprogram_Order to
28905 Style_Check_Order_Subprograms.
28907 * style.ads, styleg.ads, styleg.adb, styleg-c.adb, stylesw.ads,
28908 stylesw.adb: Add Style_Check_Xtra_Parens
28910 * usage.adb: Add line for -gnatyx (check extra parens)
28912 * vms_data.ads: Add entry for STYLE_CHECKS=XTRA_PARENS => -gnatyx
28914 2004-11-18 Ed Schonberg <schonberg@adacore.com>
28915 Robert Dewar <dewar@adacore.com>
28917 * exp_ch4.adb (Expand_N_Selected_Component): If the component is the
28918 discriminant of a constrained subtype, analyze the copy of the
28919 corresponding constraint, because in some cases it may be only
28920 partially analyzed.
28921 Removes long-lived ??? comments.
28923 * exp_ch7.adb (Establish_Transient_Scope): Remove complex code that
28924 handled controlled or secondary-stack expressions within the
28925 iteration_scheme of a loop.
28927 * sem_ch5.adb (Analyze_Iteration_Scheme): Build a block to evaluate
28928 bounds that may contain functions calls, to prevent memory leaks when
28929 the bound contains a call to a function that uses the secondary stack.
28930 (Check_Complex_Bounds): Subsidiary of Analyze_Iteration_Scheme, to
28931 generate temporaries for loop bounds that might contain function calls
28932 that require secondary stack and/or finalization actions.
28934 * sem_ch4.adb (Analyze_Indexed_Component_Form): If the prefix is a
28935 selected component and the selector is overloadable (not just a
28936 function) treat as function call, Analyze_Call will disambiguate if
28938 (Analyze_Selected_Component): Do not generate an actual subtype for the
28939 selected component if expansion is disabled. The actual subtype is only
28940 needed for constraint checks.
28941 (Analyze_Allocator): If restriction No_Streams is set, then do
28942 not permit objects to be declared of a stream type, or of a
28943 composite type containing a stream.
28945 * restrict.ads: Remove the a-stream entry from Unit_Array, since
28946 No_Streams no longer prohibits with'ing this package.
28948 * sem_ch3.adb (Build_Derived_Record_Type): If the parent type has
28949 discriminants, but the parent base has unknown discriminants, there is
28950 no discriminant constraint to inherit. Such a discrepancy can arise
28951 when the actual for a formal type with unknown discriminants is a
28952 similar private type whose full view has discriminants.
28953 (Analyze_Object_Declaration): If restriction No_Streams is set, then
28954 do not permit objects to be declared of a stream type, or of a
28955 composite type containing a stream.
28957 2004-11-18 Ed Schonberg <schonberg@adacore.com>
28959 * exp_dbug.ads: Update documentation to reflect simpler encoding for
28960 protected operations.
28962 * exp_ch9.adb (Build_Selected_Name): Do not include "PT" suffix in
28963 generated name, it complicates decoding in gdb and hinders debugging
28964 of protected operations.
28965 (Build_Barrier_Function_Specification): Set the Needs_Debug_Info
28966 flag for the protected entry barrier function.
28967 (Build_Protected_Entry_Specification): Set the Needs_Debug_Info
28968 flag for the protected entry function.
28970 2004-11-18 Nicolas Setton <setton@adacore.com>
28972 * expect.c: Define __unix__ when __APPLE__ is defined.
28974 * Makefile.in: Inform the value of the variable GMEM_LIB in the
28975 Darwin-specific section.
28977 * lang-specs.h: Change the placement of the %1 marker.
28978 Works around the fact that gcc adds -fPIC by default under Darwin.
28980 2004-11-18 Ed Schonberg <schonberg@adacore.com>
28982 * exp_pakd.adb (Convert_To_PAT_Type): After replacing the original
28983 type of the object with the packed array type, set the Analyzed flag
28984 on the object if it is an entity or simple indexed component, to avoid
28985 spurious type errors.
28987 2004-11-18 Gary Dismukes <dismukes@adacore.com>
28989 * gnat1drv.adb, gnatbind.adb, gnatchop.adb, gnatfind.adb, gnatlink.adb,
28990 gnatls.adb, gnatxref.adb, gprep.adb: Output the copyright message on a
28991 separate line from the version message.
28993 2004-11-18 Ed Falis <falis@adacore.com>
28995 * init.c (__gnat_map_signal): map SIGSEGV to Storage_Error for AE653
28997 (init_float): Eliminate initialization of floating point status for
28998 AE653. The instructions have no effect for vThreads.
29000 2004-11-18 Vincent Celier <celier@adacore.com>
29002 * make.adb (Gnatmake): Invoke gnatlink with -shared-libgcc when
29003 gnatbind is invoked with -shared.
29005 2004-11-18 Jose Ruiz <ruiz@adacore.com>
29007 * s-tposen.adb (Lock_Entry): Remove the code for raising Program_Error
29008 for Detect_Blocking which is redundant with the check done within the
29009 procedure Protected_Single_Entry_Call.
29010 (Lock_Read_Only_Entry): Remove the code for raising Program_Error for
29011 Detect_Blocking which is redundant with the check done within the
29012 procedure Protected_Single_Entry_Call.
29014 2004-11-18 Vincent Celier <celier@adacore.com>
29016 * makegpr.adb (Compile): Put the compiling switches (in package
29017 Compiler and on the command line) immediately after "-c", instead of
29018 at the end of the command line invocation of the compiler, when
29019 compiling a non-Ada file.
29020 (Build_Global_Archive): When there is no need to rebuild the archive,
29021 set Global_Archive_Exists, so that the archive is passed to the linker
29024 2004-11-18 Robert Dewar <dewar@adacore.com>
29025 Sergey Rybin <rybin@adacore.com>
29028 Remove extra paren check from list of checks for redundant constructs
29029 Add documentation of new -gnatyx style check (check extra parens)
29030 Remove paragraph about gnatelim debug options.
29032 * gnat_rm.texi: Document that Ada.Streams now forbids creating stream
29033 objects rather than forbidding dependencies on the package Ada.Streams.
29035 * sinfo.ads: Add ??? note that we should document pragmas passed to
29038 * g-expect.ads: Fix a few typos in the comments.
29040 2004-11-09 Joseph S. Myers <joseph@codesourcery.com>
29042 * misc.c (gnat_handle_option): Use %< and %> for quoting in
29045 2004-11-08 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
29047 * a-numaux-x86.adb (Tan): Fix fdivp syntax.
29049 2004-11-07 Andreas Schwab <schwab@suse.de>
29051 * Makefile.in (install-gnatlib): Remove spurious hyphen.
29053 2004-11-02 Andrew Pinski <pinskia@physics.uc.edu>
29056 * Makefile.in (darwin): Set soext to .dylib.
29058 2004-10-26 Vincent Celier <celier@gnat.com>
29059 Thomas Quinot <quinot@act-europe.fr>
29061 * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads:
29062 (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as
29063 there is no use of GNAT.Sockets.Constants.
29064 Remove remaining pragma Import for C_Write
29065 Remove C_Read and C_Write from internal implementation unit
29066 GNAT.Sockets.Thin, as their usage for sockets is non-portable (using
29067 the read and write functions from the system runtime library is fine
29068 on UNIX but won't work under Windows).
29070 * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write.
29071 (Check_Selector): Use C_Recv instead of C_Read.
29072 Selectors are the GNAT.Sockets abstraction to perform a select()
29073 call on a set of descriptors. To allow abortion of an ongoing
29074 select operation, some data is written to a dedicated socket that
29075 is always monitored.
29076 Under Windows, the write and read library functions cannot operate
29077 on sockets, so we need to use send and recv instead, which is portable
29078 across all supported platforms.
29080 * g-socthi.ads: Remove C_Read and C_Write from internal implementation
29081 unit GNAT.Sockets.Thin, as their usage for sockets is non-portable
29082 (using the read and write functions from the system runtime library is
29083 fine on UNIX but won't work under Windows).
29085 2004-10-26 Nicolas Setton <setton@act-europe.fr>
29087 * mlib-tgt-darwin.adb: New file.
29089 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29090 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29091 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb,
29092 mlib-tgt-mingw.adb, mlib-tgt-vxworks.adb (Archive_Indexer_Options): New
29095 * Makefile.in: Add support for building shared libraries under Darwin.
29096 (EXTRA_GNATRTL_NONTASKING_OBJS, ppc-vxworks): Add s-vxwexc.o, containing
29097 the low level EH init subprogram to be called from __gnat_initialize.
29099 * mlib-tgt.ads, mlib-tgt.adb (Archive_Indexer_Options): New subprogram,
29100 indicates which options to pass to the archive indexer.
29102 * mlib-utl.adb: Add support for calling ranlib with additional
29103 options. This is needed for instance under Mac OS X.
29104 (Ranlib_Options): New global variable, used to store the potential
29105 options to pass to ranlib.
29106 (Ar): Use Ranlib_Options when spawning ranlib.
29107 (Initialize): Set the value of ranlib option.
29109 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29111 * s-parame-linux.adb (Minimum_Stack_Size): Adjust to return 12K
29112 instead of 8K, to reflect the real potential needs for stack-checking
29115 2004-10-26 Pascal Obry <obry@gnat.com>
29117 * s-parame-mingw.adb (Default_Stack_Size): Add some comments.
29119 * s-taprop-mingw.adb (Create_Task): Set initial stack size to 1024. On
29120 Windows only the initial thread stack size can be set so it is good to
29121 start we a low stack size.
29122 The OS will adjust the size as needed.
29124 2004-10-26 Olivier Hainque <hainque@act-europe.fr>
29125 Nicolas Setton <setton@act-europe.fr>
29127 * expect.c, adaint.c, link.c, sysdep.c (unix sections): Guard with
29128 "__unix__" instead of "unix".
29129 The latter is implicitly defined by gcc3.2 but not by gcc >= 3.4, so the
29130 sections were just mistakenly ignored. The former is
29131 implicitely defined by gcc2.8, gcc3.2 and gcc3.4.
29132 Update #ifdef preprocessor macro to detect the symbol __hpux__ instead
29133 of hpux. This prevents an unwanted definition of the symbol
29134 convert_addresses in adaint.o.
29136 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29138 * a-exexpr.adb (Setup_Key): Change initial value to 16#DEAD#, for
29139 compatibility with type Unwind_Word on 16-bit targets such as AAMP.
29141 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29143 * a-filico.ads, a-filico.adb: fix incorrect header.
29145 2004-10-26 Javier Miranda <miranda@gnat.com>
29147 * a-ststio.ads: Fix typo in identifier
29149 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29151 * sem_ch4.adb: Minor reformatting.
29153 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29155 * checks.adb (Expr_Known_Valid): If floating-point validity checks are
29156 enabled, check the result of unary and binary operations when the
29157 expression is the right-hand side of an assignment.
29159 2004-10-26 Vincent Celier <celier@gnat.com>
29161 * clean.adb (Delete): Do not output warnings when in quiet output and
29162 not in verbose mode.
29163 (Force_Deletions): New Boolean flag, defaulted to False
29164 (Delete): Only delete a file if it is writable, and when
29165 Force_Deletions is True.
29166 (Parse_Cmd_Line): New switch -f: set Force_Deletions to True
29167 (Usage): Line for new switch -f
29168 (Clean_Directory): Use GNAT.OS_Lib.Set_Writable instead of rolling our
29171 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29173 * decl.c (gnat_to_gnu_field): Use the type of the inner object for a
29174 JM type only if its size matches that of the wrapper. When a size is
29175 prescribed and the field is not aliased, remove the wrapper of a JM
29176 type only if the size is not greater than that of the packed array.
29177 (gnat_to_gnu_entity): Change the extension of packed array wrappers
29180 2004-10-26 Geert Bosch <bosch@gnat.com>
29182 * eval_fat.adb (Eps_Model,Eps_Denorm): Remove, no longer used.
29183 (Succ): Re-implement using Scaling, Exponent and Ceiling attributes.
29184 (Pred): Implement in terms of Succ.
29186 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29188 * exp_aggr.adb (Safe_Component): An aggregate component that is an
29189 unchecked conversion is safe for in-place use if the expression of the
29190 conversion is safe.
29191 (Expand_Array_Aggregate): An aggregate that initializes an allocator may
29192 be expandable in place even if the aggregate does not come from source.
29193 (Convert_Array_Aggr_In_Allocator): New procedure to initialize the
29194 designated object of an allocator in place, rather than building it
29195 first on the stack. The previous scheme forces a full copy of the array,
29196 and may be altogether unsusable if the size of the array is too large
29197 for stack allocation.
29199 2004-10-26 Robert Dewar <dewar@gnat.com>
29201 * exp_ch4.adb (Expand_N_Op_Eq): Make sure we expand a loop for array
29202 compares if the component is atomic.
29204 * exp_ch5.adb (Expand_Assign_Array): Make sure we expand a loop for
29205 array assignment if the component type is atomic.
29207 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29208 Eric Botcazou <ebotcazou@act-europe.fr>
29210 * exp_ch6.adb (Expand_Actuals): If the actual for an in-out parameter
29211 is aliased and is a by_reference type, do not pass by copy.
29212 (Expand_N_Function_Call) <Rhs_Of_Assign_Or_Decl>: New function to
29213 detect whether the call is in the right side of an assignment or
29214 the expression of an object declaration. Recurse on component
29215 association within aggregates.
29216 Call it in the condition that determines whether the temporary is
29217 necessary for correct stack-checking.
29219 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29221 * exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
29222 RACW_Type, used in the PolyORB version.
29223 Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
29224 version and the GARLIC version.
29226 * snames.ads, snames.adb, s-parint.ads, s-parint.adb:
29227 Rename RCI_Info to RCI_Locator for better consistency between the
29228 GARLIC and PolyORB versions of the distributed systems annex.
29229 (DSA_Implementation_Name): This enumeration lists the possible
29230 implementations of the Partition Communication Subsystem for the
29231 Distributed Systems Annex (DSA). The three available implementations
29232 are the dummy stub implementation (No_DSA), and two versions based on
29233 two different distribution runtime libraries: GARLIC and PolyORB. Both
29234 the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
29236 Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
29239 * rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
29240 between the GARLIC and PolyORB versions of the distributed systems
29242 Remove RE_Unbounded_Reclaim_Pool since it is unused.
29244 2004-10-26 Gary Dismukes <dismukes@gnat.com>
29246 * gnat1drv.adb: Suppress calling the back end when
29247 Frontend_Layout_On_Target is true.
29249 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29251 * g-os_lib.ads, g-os_lib.adb (Set_Executable, Set_Writable,
29252 Set_Read_Only): New subprograms.
29253 These new routines allow the user to set or unset the Owner execute
29254 and Owner write permission flags on a file.
29256 * makegpr.adb, mlib.adb, mlib-prj.adb: Use
29257 GNAT.OS_Lib.Set_Executable instead of rolling our own.
29259 2004-10-26 Matthew Gingell <gingell@gnat.com>
29261 * i-cpp.ads, i-cpp.adb: Change layout of VTable for new C++ ABI.
29263 2004-10-26 Pascal Obry <obry@gnat.com>
29265 * init.c (__gnat_error_handler) [Win32]: Instead of trying to read the
29266 memory before the faulting page we properly test the process read
29267 access for this address using appropriate Win32 routine.
29268 (HPUX sections): guard with "__hpux__" instead of "hpux".
29270 2004-10-26 Robert Dewar <dewar@gnat.com>
29272 * lib-xref.adb (Generate_Reference): Don't complain about reference to
29273 entry parameter if pragma Unreferenced set, since we do not properly
29274 handle the case of multiple parameters.
29276 2004-10-26 Vincent Celier <celier@gnat.com>
29278 * prj-env.adb: (Contains_ALI_Files): New Boolean function
29279 (Ada_Objects_Path.Add): For a library project, add to the object path
29280 the library directory only if there is no object directory or if the
29281 library directory contains ALI files.
29282 (Set_Ada_Paths.Add.Recursive_Add): Ditto
29284 2004-10-26 Vincent Celier <celier@gnat.com>
29286 * prj-nmsc.adb (Language_Independent_Check): Do not forbid virtual
29287 extension of library projects.
29289 * prj-part.adb: If env var ADA_PROJECT_PATH is not defined, project
29290 path defaults to ".:<prefix>/lib/gnat".
29291 (Parse): For an extending all project, allow direct import of a project
29292 that is virtually extended.
29294 * prj-proc.adb (Imported_Or_Extended_Project_From): If a project with
29295 the specified name is directly imported, return its ID. Otherwise, if
29296 an extension of this project is imported, return the ID of the
29299 2004-10-26 Robert Dewar <dewar@gnat.com>
29301 * s-arit64.adb: (Le3): New function, used by Scaled_Divide
29302 (Sub3): New procedure, used by Scaled_Divide
29303 (Scaled_Divide): Substantial rewrite, avoid duplicated code, and also
29304 correct more than one instance of failure to propagate carries
29306 (Double_Divide): Handle overflow case of largest negative number
29307 divided by minus one.
29309 * s-arit64.ads (Double_Divide): Document that overflow can occur in
29310 the case of a quotient value out of range.
29313 2004-10-26 Robert Dewar <dewar@gnat.com>
29315 * s-bitops.adb (Bit_Eq): Remove redundant check.
29317 * s-bitops.ads: Minor comment updates
29318 Change some occurrences of Address to System.Address
29320 * s-carsi8.ads: Fix minor cut-and-paste error in comments
29322 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29324 * sem_attr.adb (Resolve_Attribute, case 'Access): Apply proper
29325 accessibility check to prefix that is a protected operation.
29327 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29329 * sem_ch10.adb (Optional_Subunit): If file of expected subunit is
29330 empty, post message on stub.
29332 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29333 Javier Miranda <miranda@gnat.com>
29335 * sem_ch12.adb (In_Main_Context): Predicate to determine whether the
29336 current instance appears within a unit that is directly in the context
29338 Used to determine whether the body of the instance should be analyzed
29339 immediately after its spec, to make its subprogram bodies available
29340 for front-end inlining.
29341 (Analyze_Formal_Array_Type): Cleanup condition that checks that range
29342 constraint is not allowed on the component type (AARM 12.5.3(3))
29344 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29346 * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case
29347 'Storage_Pool): enhance, document & limit detection of non-sharable
29350 * impunit.adb: Make System.Pool_Global and System.Pool_Local visible.
29352 * s-pooglo.ads: Add more documentation now that this pool is properly
29355 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29357 * sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
29358 or protected type with discriminants, do not constrain the
29359 corresponding record type if the subtype declaration has no
29360 discriminant constraints. This can be the case in source code, or in
29361 the subtype declaration created to rename an actual type within an
29364 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29366 * sem_ch6.adb (Analyze_Subprogram_Body): If body is a subunit for a
29367 different kind of stub (possibly wrong name for file), do not check
29369 (Uses_Secondary_Stack): New subsidiary to Build_Body_To_Inline. If body
29370 includes call to some function that returns an unconstrained type, do
29373 2004-10-26 Ed Schonberg <schonberg@gnat.com>
29375 * sem_elab.adb (Check_Elab_Call): Do not check a call that does not
29376 appear in the code for the main unit. Dependencies among units in the
29377 context of the main unit are established when those other units are
29378 compiled. Otherwise spurious elaboration constraints can generate
29379 incorrect elaboration circularities.
29381 2004-10-26 Thomas Quinot <quinot@act-europe.fr>
29382 Ed Schonberg <schonberg@gnat.com>
29384 * sem_util.adb (Is_Aliased_View): Defend against the case where this
29385 subprogram is called with a parameter that is not an object name. This
29386 situation arises for some cases of illegal code, which is diagnosed
29387 later, and in this case it is wrong to call Is_Aliased, as that might
29388 cause a compiler crash.
29389 (Explain_Limited_Type): Refine previous fix to include
29390 inherited components of derived types, to provide complete information.
29392 * exp_ch9.adb (Set_Privals): Set the Ekind of the actual object that
29393 is the prival for a protected object.
29394 It is necessary to mark this entity as a variable, in addition to
29395 flagging it as Aliased, because Sem_Util.Is_Aliased_View has been
29396 modified to avoid checking the Aliased flag on entities that are not
29397 objects. (Checking that flag for non-objects is erroneous and could
29398 lead to a compiler crash).
29400 2004-10-26 Robert Dewar <dewar@gnat.com>
29402 * s-fatgen.adb (Pred): Fix redundant test for X > 0.0, since if
29403 X_Frac = 0.5, then we know that the number X must be positive.
29404 (Succ): Remove the same redundant test, and also fix the primary test
29405 to test for X_Frac = -0.5 (used to be 0.5) which is clearly wrong.
29407 (Decompose): Add fuller comments to spec
29409 2004-10-26 Pascal Obry <obry@gnat.com>
29411 * tracebak.c (IS_BAD_PTR): Use IsBadCodePtr on Win32 to check for ptr
29412 validity (process must have read access). Set to 0 in all other cases.
29413 (STOP_FRAME): Now check for ptr validity to avoid a segmentation
29414 violation on Win32.
29415 (VALID_STACK_FRAME): Check for ptr validity on Win32 to avoid a
29416 segmentation violation.
29418 2004-10-26 Eric Botcazou <ebotcazou@act-europe.fr>
29420 * trans.c (call_to_gnu): For an (in-)out parameter passed by reference
29421 whose type is a constructed subtype of an aliased object with an
29422 unconstrained nominal subtype, convert the actual to the constructed
29423 subtype before taking its address.
29425 2004-10-26 Vincent Celier <celier@gnat.com>
29427 * a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
29428 (Is_Path_Name_Case_Sensitive): New function
29430 * a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
29431 (Base_Name, Simple_Name, Current_Directory, Compose,
29432 Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
29435 2004-10-26 Cyrille Comar <comar@act-europe.fr>
29436 Vasiliy Fofanov <fofanov@act-europe.fr>
29437 Vincent Celier <celier@gnat.com>
29439 * gnat_ugn.texi: Generalize "finding memory problems" section into a
29440 "memory management issues" section and document some of the useful
29441 memory pools provided as part of the GNAT library.
29442 Remove "virtual" from declaration of A::method2 in
29443 the simple example of Ada/C++ mixed system.
29444 Library Projects may be virtually extended: their virtual extensions
29445 are not Library Projects.
29446 Added section on extending project hierarchies.
29448 2004-10-19 Aaron W. LaFramboise <aaronavay62@aaronwl.com>
29450 * adaint.c (__gnat_get_libraries_from_registry): Cast value
29452 (__gnat_portable_spawn): Remove const.
29454 * mingw32.h (MAXPATHLEN): Check for previous definition.
29456 2004-10-17 Matthias Klose <doko@debian.org>
29458 * gnatvsn.ads: Set gnat library version to 4.0.
29460 2004-10-05 Vincent Celier <celier@gnat.com>
29462 * mlib-tgt.ads: (Build_Dynamic_Library): New parameter Options_2
29464 2004-10-04 Laurent Guerby <laurent@guerby.net>
29467 * Makefile.in: Define and use RANLIB_FLAGS.
29469 2004-10-04 Pascal Obry <obry@gnat.com>
29471 * tracebak.c: Always set LOWEST_ADDR to 0 on Win32 (as done on all
29472 other x86 platforms).
29474 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
29476 * s-tassta.adb (Task_Wrapper): Make it Convention C, which makes sense
29477 in general and triggers stack alignment adjustment for thread entry
29478 points on targets where this is necessary.
29480 2004-10-04 Bernard Banner <banner@gnat.com>
29483 * Makefile.in: Add section for powerpc linux
29484 Add variant i-vxwork-x86.ads
29486 * i-vxwork-x86.ads, system-linux-ppc.ads: New files.
29488 2004-10-04 Olivier Hainque <hainque@act-europe.fr>
29490 * init.c (__gnat_initialize): Call an Ada subprogram to perform the
29491 table registration calls when need be. Ensures no reference to the crt
29492 ctors symbol are issued in the SJLJ case, which avoids possible
29493 undefined symbol errors in the case of modules to be statically linked
29496 2004-10-04 Javier Miranda <miranda@gnat.com>
29498 * sem_ch4.adb (Try_Object_Operation): Reformat the code to expand
29499 in-line the code corresponding to subprogram Analyze_Actuals. In
29500 addition, analyze the actuals only in case of subprogram call.
29502 2004-10-04 Ed Falis <falis@gnat.com>
29504 * s-vxwork-x86.ads: (FP_CONTEXT): Defined to be correct size
29506 2004-10-04 Sergey Rybin <rybin@act-europe.fr>
29508 * g-dirope.ads (Base_Name): Clarify the meaning of the Suffix parameter
29509 in the documentation.
29511 2004-10-04 Robert Dewar <dewar@gnat.com>
29513 * sem_ch5.adb (Unblocked_Exit_Count): Now used for blocks as well as
29515 (Analyze_Block_Statement): Add circuitry to detect following dead code
29516 (Check_Unreachable_Code): Handle case of block exit
29518 2004-10-04 Robert Dewar <dewar@gnat.com>
29520 * g-spipat.adb: (XMatch): Avoid warning for Logic_Error call
29521 (XMatchD): Avoid warning for Logic_Error call
29523 2004-10-04 Robert Dewar <dewar@gnat.com>
29525 * exp_ch4.adb (Is_Procedure_Actual): Correct so that this does not
29526 consider expressions buried within a procedure actual to be an actual.
29527 This caused some blowups with uses of packed slices within a procedure
29530 2004-10-04 Robert Dewar <dewar@gnat.com>
29532 * exp_ch3.adb (Needs_Simple_Initialization): Modular packed arrays no
29533 longer need to be initialized to zero.
29534 (Get_Simple_Init_Val): Modular packed arrays no longer need to be
29535 initialized to zero.
29537 * checks.adb (Expr_Known_Valid): Packed arrays are now always
29538 considered valid, even if the representation is modular. That's correct
29539 now that we no longer initialize packed modular arrays to zero.
29541 * exp_dbug.ads: Clarify documentation on handling of PAD and JM
29542 suffixes. These are now documented as the only cases in which the
29543 debugger ignores outer records.
29544 Previously, the spec allowed arbitrary suffixes for this purpose.
29545 Change name of LJM to JM for packed array pad records
29546 Create separate section on packed array handling, and add a whole new
29547 set of comments to this section describing the situation with packed
29548 modular types and justification requirements depending on endianness.
29550 2004-10-04 Robert Dewar <dewar@gnat.com>
29552 * a-except.adb: Add a comment for last change
29554 * einfo.ads: Minor spelling correction in comment
29556 * exp_pakd.adb, gnatdll.adb, prj-attr.ads: Minor reformatting
29558 * sem_ch11.adb: Fix a case of using | instead of \ for continuation
29561 * sem_util.ads: Minor comment update
29563 2004-10-04 Ed Schonberg <schonberg@gnat.com>
29565 * sem_ch6.adb (Analyze_Subprogram_Body): Do not treat Inline as
29566 Inline_Always when in Configurable_Run_Time mode.
29568 * sem_prag.adb (Process_Convention): If entity is an inherited
29569 subprogram, apply convention to parent subprogram if in same scope.
29570 (Analyze_Pragma, case Inline): Do not treat Inline as Inline_Always
29571 when in Configurable_Run_Time mode.
29573 2004-10-04 Ed Schonberg <schonberg@gnat.com>
29575 * sem_ch3.adb (Build_Derived_Record_Type): Set First/Last entity of
29576 class_wide type after component list has been inherited.
29578 2004-10-04 Ed Schonberg <schonberg@gnat.com>
29580 * sem_ch12.adb (Check_Generic_Actuals): New predicate
29581 Denotes_Previous_Actual, to handle properly the case of a private
29582 actual that is also the component type of a subsequent array actual.
29583 The visibility status of the first actual is not affected when the
29584 second is installed.
29585 (Process_Nested_Formal): Subsidiary of Instantiate_Formal_Package, to
29586 make fully recursive the treatment of formals of packages declared
29588 (Restore_Nested_Formal): Subsidiary of Restore_Private_Views, to undo
29589 the above on exit from an instantiation.
29590 (Denotes_Formal_Package): When called from Restore_Private_Views, ignore
29591 current instantiation which is now complete.
29592 (Analyze_Package_Instantiation): No instantiated body is needed if the
29593 main unit is generic. Efficient, and avoid anomalies when a instance
29594 appears in a package accessed through rtsfind.
29596 2004-10-04 Ed Schonberg <schonberg@gnat.com>
29598 * exp_ch6.adb (Expand_N_Function_Call): If stack checking is enabled,
29599 do not generate a declaration for a temporary if the call is part of a
29600 library-level instantiation.
29602 2004-10-04 Ed Schonberg <schonberg@gnat.com>
29604 * sem_util.adb (Explain_Limited_Type): Ignore internal components when
29605 searching for a limited component to flag.
29607 * exp_attr.adb (Freeze_Stream_Subprogram): Subsidiary procedure to
29608 expansion of Input, to account for the fact that the implicit call
29609 generated by the attribute reference must freeze the user-defined
29610 stream subprogram. This is only relevant to 'Input, because it can
29611 appear in an object declaration, prior to the body of the subprogram.
29613 * sem_ch13.adb (Rep_Item_Too_Late): Make the error non-serious, so that
29614 expansion can proceed and further errors uncovered.
29615 (Minor clean up): Fix cases of using | instead of \ for continuation
29618 2004-10-04 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
29620 * cuintp.c, decl.c, utils2.c: Use gcc_assert and gcc_unreachable.
29622 * trans.c (assoc_to_constructor): Fix unused var warning if no checking.
29623 (gnat_gimplify_expr, case ADDR_EXPR): Fix error in last change.

29626 * decl.c (gnat_to_gnu_entity, case object): Check and process a
29627 specified alignment before validating size.
29628 (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Create a
29629 stripped-down declaration for the type of the inner field when making
29632 * utils.c (finish_record_type): Do not compute the size in units
29633 incrementally. Instead compute it once for the rep clause case.
29634 Use gcc_assert and gcc_unreachable.
29636 2004-10-04 Vincent Celier <celier@gnat.com>
29638 * a-dirval-mingw.adb (Invalid_Character): Add '\' as invalid character
29640 (Is_Valid_Path_Name): Take '/' as a directory separator.
29642 2004-10-04 Vincent Celier <celier@gnat.com>
29644 * prj-part.adb (Parse_Single_Project): Call Is_Extending_All
29645 (Extended_Project) only if Extended_Project is defined, to avoid
29647 (Post_Parse_Context_Clause): Always call Set_Path_Name_Of with a
29649 (Parse_Single_Project): Ditto.
29651 * prj-env.adb (Set_Ada_Paths.Add.Recursive_Add): Do not call
29652 Add_To_Project_Path for virtual projects.
29654 2004-10-04 Vincent Celier <celier@gnat.com>
29656 * mlib-tgt-tru64.adb, mlib-tgt-aix.adb, mlib-tgt-irix.adb,
29657 mlib-tgt-hpux.adb, mlib-tgt-linux.adb, mlib-tgt-solaris.adb,
29658 mlib-tgt-vms-alpha.adb, mlib-tgt-vms-ia64.adb, mlib-tgt-mingw.adb,
29659 mlib-tgt-vxworks.adb, mlib-tgt.adb (Build_Dynamic_Library): New
29660 parameter Options_2.
29662 * mlib-prj.ads, mlib-prj.adb (Build_Library): Call
29663 Build_Dynamic_Library with an empty Options_2.
29665 * mlib-utl.ads, mlib-utl.adb (Gcc): Parameter Options_2 has no
29668 * makegpr.adb (Get_Imported_Directories.add): Remove trailing
29669 directory separator, if any.
29670 (Gprmake): Do not allow mains on the command line for library projects.
29671 Do not attempt to link when the project is a library project.
29672 (Library_Opts): New table to store Library_Options.
29673 (Build_Library): If Library_Options is specified, pass these options
29674 when building a shared library.
29676 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
29678 * s-tposen.adb (Service_Entry): The object must be always unlocked at
29679 the end of this procedure now that the unlock operation was inserted
29682 2004-10-04 Jose Ruiz <ruiz@act-europe.fr>
29684 * targparm.ads, targparm.adb (Targparm_Tags): Add PAS value
29685 corresponding to the Preallocated_Stacks flags in System.
29686 (Get_Target_Parameters): Including the processing for
29687 Preallocated_Stacks.
29689 * system.ads, system-vxworks-x86.ads, system-darwin-ppc.ads,

29698 system-mingw.ads, system-vms-zcx.ads, system-vxworks-ppc.ads,
29699 system-vxworks-alpha.ads: Add the flag Preallocated_Stacks, that is
29700 used to signal whether the compiler creates the required stacks and
29701 descriptors for the different tasks (when True) or it is done by the
29702 underlying operating system at run time (when False).
29703 It is initially set to False in all targets.
29705 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Create the task stack
29706 if it is supported by the target.
29707 (Make_Task_Create_Call): Pass the stack address if it has been
29708 previously created. Otherwise pass a Null_Address.
29710 * snames.adb: Add _stack.
29712 * snames.ads: Add Name_uStack. Required to allow the expander to
29713 statically allocated task stacks.
29715 * s-tarest.ads, s-tarest.adb (Create_Restricted_Task): Add
29716 Stack_Address argument.
29717 Check that its value is equal to Null_Address because this target does
29718 not support the static stack allocation.
29720 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
29722 * usage.adb: Change "pragma inline" to "pragma Inline" in information
29725 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
29727 * exp_dist.adb: Split declaration of asynchronous flag out of
29728 Add_RACW_Read_Attribute.
29729 Minor reformatting for better alignment with PolyORB version.
29730 Store the entity for the asynchronous flag of an RACW, rather than the
29731 expression, in the asynchronous flags table. This will allow this flag
29732 to be used in other subprograms beside Add_RACW_Read_Attribute.
29734 2004-10-04 Thomas Quinot <quinot@act-europe.fr>
29736 * g-socket.ads, g-socket.adb, g-socthi.adb, socket.c,

29740 g-soccon.ads, g-soccon-unixware.ads, g-soccon-tru64.ads: Add new
29741 sockets constant MSG_NOSIGNAL (Linux-specific).
29742 Add new sockets constant MSG_Forced_Flags, list of flags to be set on
29743 all Send operations.
29744 For Linux, set MSG_NOSIGNAL on all send operations to prevent them
29745 from trigerring SIGPIPE.
29746 Rename components to avoid clash with Ada 2005 possible reserved
29748 (Check_Selector): When the select system call returns with an error
29749 condition, propagate Socket_Error to the caller.
29751 2004-10-01 Jan Hubicka <jh@suse.cz>
29753 * misc.c (gnat_expand_body): Update call of tree_rest_of_compilation.
29755 2004-09-23 Robert Dewar <dewar@gnat.com>
29758 * sem_prag.adb (Process_Import_Or_Interface): Don't set Is_Public here,
29759 instead do this at freeze time (we won't do it if there is an address
29761 Change "pragma inline" to "pragma Inline" in information and error
29763 Minor reformatting.
29765 * freeze.adb (Check_Address_Clause): Remove previous change, not the
29766 right way of doing things after all.
29767 (Freeze_Entity): For object, set Is_Public for imported entities
29768 unless there is an address clause present.
29770 2004-09-21 Olivier Hainque <hainque@act-europe.fr>
29772 * decl.c (gnat_to_gnu_entity) <E_General_Access_Type>: Check for a
29773 dummy designated type via TYPE_MODE instead of COMPLETE_TYPE_P. This
29774 ensures proper handling of types with rep clauses, which might have
29775 their TYPE_SIZE set already.
29777 2004-09-21 Robert Dewar <dewar@gnat.com>
29779 * decl.c (gnat_to_gnu_type, case E_Modular_Integer_Type): Wrap modular
29780 packed array types in both little- and big-endian cases. This change
29781 ensures that we no longer count on the unused bits being initialized
29782 for such types (and in particular ensures that equality testing will
29783 only read the relevant bits).
29784 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
29785 These changes mean that we no longer need to initialize small packed
29787 (gnat_to_gnu_entity) <E_Record_Subtype>: Apply the same
29788 optimization to an LJM field as to its parent field.
29790 * ada-tree.h, trans.c, utils.c, utils2.c:
29791 Change name TYPE_LEFT_JUSTIFIED_MODULAR_P to TYPE_JUSTIFIED_MODULAR_P
29793 2004-09-20 Jan Hubicka <jh@suse.cz>
29795 * utils.c (gnat_finalize): Remove.
29796 (end_subprog_body): Directly call cgraph_finalize_function;
29797 do not lower the nested functions.
29799 2004-09-20 Robert Dewar <dewar@gnat.com>
29802 * freeze.adb (Check_Address_Clause): Reset Is_Imported and Is_Public
29803 if an address clause is present, since that means that the Import
29806 2004-09-20 Arnaud Charlet <charlet@act-europe.fr>
29808 * 5tsystem.ads: Removed, no longer used.
29810 2004-09-17 Jeffrey D. Oldham <oldham@codesourcery.com>

29832 an existing directory.
29833 (Fetch_Next_Entry): Give default value to variable Kind to avoid warning
29834 (Size (String)): Function C_Size returns Long_Integer, not File_Size.
29835 Convert the result to File_Size.
29837 * prj.ads: (Project_Error): New exception
29839 * prj-attr.adb: Except in procedure Initialize, Fail comes from
29840 Prj.Com, not from Osint.
29841 (Attrs, Package_Attributes): Tables moved to private part of spec
29842 (Add_Attribute, Add_Unknown_Package): Moved to new child package
29844 (Register_New_Package (Name, Attributes), Register_New_Attribute): Raise
29845 Prj.Project_Error after call to Fail.
29846 (Register_New_Package (Name, Id)): Set Id to Empty_Package after calling
29847 Fail. Check that package name is not already in use.
29849 * prj-attr.ads: Comment updates to indicate that all subprograms may be
29850 used by tools, not only by the project manager, and to indicate that
29851 exception Prj.Prj_Error may be raised in case of problem.
29852 (Add_Unknown_Package, Add_Attribute): Moved to new child package
29854 (Attrs, Package_Attributes): Table instantiations moved from the body to
29855 the private part to be accessible from Prj.Attr.PM body.
29857 * prj-dect.adb (Parse_Package_Declaration): Call Add_Unknown_Package
29858 from new package Prj.Attr.PM.
29859 (Parse_Attribute_Declaration): Call Add_Attribute from new package
29862 * Makefile.in: Add prj-attr-pm.o to gnatmake object list
29864 * gnatbind.adb (Gnatbind): Correct warning message (Elaboration_Check
29865 instead of Elaboration_Checks).
29867 * a-calend.adb: Minor reformatting
29869 2004-09-09 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

29907 2004-09-09 Jose Ruiz <ruiz@act-europe.fr>
29909 * gnat_ugn.texi: Add Detect_Blocking to the list of configuration
29910 pragmas recognized by GNAT.
29912 * gnat_rm.texi: Document pragma Detect_Blocking.
29914 * s-solita.adb (Timed_Delay_T): When pragma Detect_Blocking is active,
29915 raise Program_Error if called from a protected operation.
29917 * s-taprob.adb (Lock): When pragma Detect_Blocking is active increase
29918 the protected action nesting level.
29919 (Lock_Read_Only): When pragma Detect_Blocking is active increase the
29920 protected action nesting level.
29921 (Unlock): When pragma Detect_Blocking is active decrease the protected
29922 action nesting level.
29924 * s-taskin.adb (Initialize_ATCB): Initialize to 0 the
29925 Protected_Action_Nesting.
29927 * s-taskin.ads: Adding the field Protected_Action_Nesting to the
29928 Common_ATCB record. It contains the dynamic level of protected action
29929 nesting for each task. It is needed for checking whether potentially
29930 blocking operations are called from protected operations.
29931 (Detect_Blocking): Adding a Boolean constant reflecting whether pragma
29932 Detect_Blocking is active or not in the partition.
29934 * s-tasren.adb (Call_Simple): When pragma Detect_Blocking is active,
29935 raise Program_Error if called from a protected operation.

29945 raise Program_Error if called from a protected operation, and increase
29946 the protected action nesting level.
29947 (Lock_Read_Only_Entries): When pragma Detect_Blocking is active, raise
29948 Program_Error if called from a protected operation, and increase the
29949 protected action nesting level.

29955 the protected action nesting level.
29956 (Lock_Read_Only_Entry): When pragma Detect_Blocking is active, raise
29957 Program_Error if called from a protected operation, and increase the
29958 protected action nesting level.

29966 * sem_util.adb (Check_Potentially_Blocking_Operation): Remove the
29967 insertion of the statement raising Program_Error. The run time
29968 contains the required machinery for handling that.
29970 * sem_util.ads: Change comment associated to procedure
29971 Check_Potentially_Blocking_Operation.
29972 This procedure does not insert a call for raising the exception because
29973 that is currently done by the run time.
29975 * raise.h (__gnat_set_globals): Pass the detect_blocking parameter.
29977 * init.c: Add the global variable __gl_detect_blocking that indicates
29978 whether pragma Detect_Blocking is active (1) or not (0). Needed for
29979 making the pragma available at run time.
29980 (__gnat_set_globals): Pass and update the detect_blocking parameter.
29982 * lib-writ.adb (Write_ALI): Set the DB flag in the ali file if
29983 pragma Detect_Blocking is active.
29985 * lib-writ.ads: Document the Detect_Blocking flag (DB) in ali files.
29987 * ali.adb (Scan_ALI): Set the Detect_Blocking value to true if the flag
29988 DB is found in the ali file. Any unit compiled with pragma
29989 Detect_Blocking active forces its effect in the whole partition.
29991 * a-retide.adb (Delay_Until): Raise Program_Error if pragma
29992 Detect_Blocking is active and delay is called from a protected
29995 * bindgen.adb (Gen_Adainit_Ada): When generating the call to
29996 __gnat_set_globals, pass 1 as Detect_Blocking parameter if pragma
29997 Detect_Blocking is active (0 otherwise).
29998 (Gen_Adainit_C): When generating the call to __gnat_set_globals, pass 1
29999 as Detect_Blocking parameter if pragma Detect_Blocking is active (0
30002 2004-09-09 Thomas Quinot <quinot@act-europe.fr>
30004 * gnat_rm.texi: Rename GNAT.Perfect_Hash.Generators to
30005 GNAT.Perfect_Hash_Generators, and remove the empty GNAT.Perfect_Hash
30008 * s-parint.ads, s-parint.adb (Get_RAS_Info): New subprogram.
30009 (Register_Receiving_Stub): Add Subp_Info formal parameter.
30010 Update API in placeholder implemetation of s-parint to reflect changes
30011 in distribution runtime library.
30013 * sem_ch3.adb (Expand_Derived_Record): Rename to
30014 Expand_Record_Extension.
30016 * sem_disp.adb (Check_Controlling_Formals): Improve error message for
30017 primitive operations of potentially distributed object types that have
30018 non-controlling anonymous access formals.
30020 * sem_dist.ads, sem_dist.adb (Build_RAS_Primitive_Specification): New
30022 New implementation of expansion for remote access-to-subprogram types,
30023 based on the RACW infrastructure.
30024 This version of sem_dist is compatible with PolyORB/DSA as well as
30027 * sem_prag.adb (Analyze_Pragma, case Pragma_Asynchronous): For a pragma
30028 Asynchrronous that applies to a remote access-to-subprogram type, mark
30029 the underlying RACW type as asynchronous.
30031 * link.c: FreeBSD uses GNU ld: set __gnat_objlist_file_supported and
30032 __gnat_using_gnu_linker to 1.
30034 * Makefile.rtl, impunit.adb, g-perhas.ads, g-pehage.ads,
30035 g-pehage.adb: Rename GNAT.Perfect_Hash.Generators to
30036 GNAT.Perfect_Hash_Generators, and remove the empty

30041 * exp_ch3.adb (Expand_Derived_Record): Rename to
30042 Expand_Record_Extension.
30043 (Build_Record_Init_Proc.Build_Assignment): The default expression in
30044 a component declaration must remain attached at that point in the
30045 tree so New_Copy_Tree copies it if the enclosing record type is derived.
30046 It is therefore necessary to take a copy of the expression when building
30047 the corresponding assignment statement in the init proc.
30048 As a side effect, in the case of a derived record type, we now see the
30049 original expression, without any rewriting that could have occurred
30050 during expansion of the ancestor type's init proc, and we do not need
30051 to go back to Original_Node.
30053 * exp_ch3.ads (Expand_Derived_Record): Rename to
30054 Expand_Record_Extension.
30056 * exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.
30057 Returns the RACW type used to implement a remote access-to-subprogram
30059 (Add_RAS_Proxy_And_Analyze, Build_Remote_Subprogram_Proxy_Type):
30060 New subprograms. Used to create a proxy tagged object for a remote
30061 subprogram. The proxy object is used as the designated object
30062 for RAS values on the same partition (unless All_Calls_Remote applies).
30063 (Build_Get_Unique_RP_Call): New subprogram. Build a call to
30064 System.Partition_Interface.Get_Unique_Remote_Pointer.
30065 (Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
30066 Renamed from Add_RAS_*_Attribute.
30067 (Add_Receiving_Stubs_To_Declarations): Generate a table of local
30069 New implementation of expansion for remote access-to-subprogram types,
30070 based on the RACW infrastructure.
30072 * exp_dist.ads (Copy_Specification): Update comment to note that this
30073 function can copy the specification from either a subprogram
30074 specification or an access-to-subprogram type definition.
30076 2004-09-09 Ed Schonberg <schonberg@gnat.com>
30078 * sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
30079 in an instance, between an explicit subprogram an one inherited from a
30080 type derived from an actual.
30082 * exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
30083 add a polling call if the subprogram is to be inlined by the back-end,
30084 to avoid repeated calls with multiple inlinings.
30086 * checks.adb (Apply_Alignment_Check): If the expression in the address
30087 clause is a call whose name is not a static entity (e.g. a dispatching
30088 call), treat as dynamic.
30090 2004-09-09 Robert Dewar <dewar@gnat.com>
30092 * g-trasym.ads: Minor reformatting
30094 * exp_ch3.adb (Component_Needs_Simple_Initialization): Don't except
30095 packed arrays, since unused bits are expected to be zero for a

30100 * exp_pakd.ads: Fix an inacurracy and a couple of typos in the head
30103 2004-09-09 Pascal Obry <obry@gnat.com>
30105 * mdll.ads, mdll.adb (Build_Dynamic_Library): New parameter Map_File to
30106 enable map file generation. Add the right option to generate the map
30107 file if Map_File is set to True.
30109 * gnatdll.adb (Gen_Map_File): New variable.
30110 (Syntax): Add info about new -m (Map_File) option.
30111 (Parse_Command_Line): Add support for -m option.
30112 (gnatdll): Pass Gen_Map_File to Build_Dynamic_Library calls.

30118 new gnatdist implementation.
30119 Define a subpackage isolating the output routines specific to this
30122 2004-09-09 Joel Brobecker <brobecker@gnat.com>
30124 * Makefile.rtl: (GNATRTL_NONTASKING_OBJS): Add g-dynhta.
30126 * gnat_ugn.texi (Main Subprograms): Fix typo. Deduced, not deducted.
30128 2004-09-09 Cyrille Comar <comar@act-europe.fr>
30130 * opt.adb (Set_Opt_Config_Switches): Use Ada_Version_Runtime to compile
30133 * opt.ads: Add Ada_Version_Runtime constant used to decide which
30134 version of the language is used to compile the run time.
30136 2004-09-09 Arnaud Charlet <charlet@act-europe.fr>
30138 * sem_util.adb (Requires_Transient_Scope): Re-enable handling
30139 of variable length temporaries for function return now that the
30140 back-end and gigi support it.
30142 2004-09-01 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>

30192 packed indexed component where array is an IN OUT formal. This
30193 generated garbage code previously.
30195 * gnat_ugn.texi: Document -fverbose-asm
30197 * gnat-style.texi: Minor updates (note that boolean constants and
30198 variables are joined with AND/OR rather than short circuit forms).
30200 2004-09-01 Ed Schonberg <schonberg@gnat.com>
30202 * exp_util.adb (Safe_Unchecked_Type_Conversion): Conversion is safe if
30203 it is an upward conversion of an untagged type with no representation
30206 2004-09-01 Thomas Quinot <quinot@act-europe.fr>
30208 * rtsfind.ads: Move RCI_Subp_Info and RCI_Subp_Info_Array to
30209 System.Partition_Interface.
30211 * checks.adb (Apply_Access_Checks): Do not generate checks when

30215 * sem_prag.adb (Analyze_Pragma, case Pragma_Debug): Uniformly rewrite
30216 pragma Debug as an if statement with a constant condition, for
30217 consistent treatment of entity references contained within the
30218 enclosed procedure call.
30220 2004-09-01 Vincent Celier <celier@gnat.com>
30222 * bindgen.adb: (Set_EA_Last): New procedure
30223 (Gen_Exception_Table_Ada, Gen_Exception_Table_C): Use new procedure
30225 (Gen_Adafinal_Ada): If no finalization, adafinal does nothing
30226 (Gen_Output_File_Ada): Always call Gen_Adafinal_Ada, so that SAL can be
30227 linked without errors.
30228 (Gen_Exception_Table_Ada): Correct bugs when generating code for arrays

30232 * vms_data.ads: Add new qualifier /VERBOSE_ASM to GCC_Switches
30234 * g-os_lib.adb (Normalize_Pathname.Get_Directory): When Dir is empty,
30235 on Windows, make sure that the drive letter is in upper case.
30237 * g-os_lib.ads (Normalize_Pathname): Add a comment to indicate that on

30247 2004-09-01 Pascal Obry <obry@gnat.com>
30249 * gprcmd.adb (Extend): Do not output trailing directory separator. This
30250 is not needed and it confuses Windows GNU/make which does not report
30251 directory terminated by a slash as a directory.
30252 (gprcmd): Idem for "pwd" internal command.
30254 * Makefile.generic: Use __GPRCOLON__ instead of pipe character in
30255 target names rewrite to fix regressions with recent version of
30256 GNU/make. Starting with GNU/make 3.80 the pipe character was not
30257 handled properly anymore.

30334 for a global aliased object with a variable size and an unconstrained
30335 nominal subtype, pretend there is no initializer if the one we have is
30336 incomplete, and avoid referencing an inexistant component in there. The

30361 unit, this is an attempt to inline a construct that is not available in
30362 the current restricted mode, so abort rather than trying to continue.
30364 * sem_ch3.adb (Build_Underlying_Full_View): If the new type has
30365 discriminants that rename those of the parent, recover names of
30366 original discriminants for the constraint on the full view of the

30397 returning C.int, to avoid using a derived boolean type.
30399 * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use

32753 * gnat_ugn.texi: Minor change to -gnatS documentation
32755 * sprint.adb: Remove some instances of Assert (False) and for this
32756 purpose replace them by output of a ??? string.
32758 * checks.adb, exp_aggr.adb, sem_elim.adb: Remove useless pragma
32761 * lib-writ.adb, lib-load.adb, lib.ads, lib.adb: Remove Dependent_Unit
32762 flag processing. This was suppressing required dependencies in
32763 No_Run_Time mode and is not needed since the binder does not generate
32764 references for things in libgnat anyway.
32766 * sem_ch3.adb (Access_Type_Declaration): Reorganize code to avoid GCC
32769 2004-05-14 Thomas Quinot <quinot@act-europe.fr>
32771 * gnat_ugn.texi: Document AIX-specific issue with initialization of

32775 action for the case of an actual parameter in an init proc call.
32777 2004-05-14 Ed Schonberg <schonberg@gnat.com>
32779 * sem_ch4.adb (Analyze_Selected_Component): If prefix is a protected
32780 subtype, check visible entities in base type.
32782 * exp_ch7.adb (Clean_Simple_Protected_Objects): Do not generate cleanup
32783 actions if the object is a renaming.
32785 * sem_ch12.adb (Same_Instantiated_Entity): Predicate for
32786 Check_Formal_Package_Instance, to determine more precisely when the
32787 formal and the actual denote the same entity.
32789 2004-05-14 Javier Miranda <miranda@gnat.com>
32791 * par-ch10.adb (P_Context_Clause): Complete documentation on AI-262
32793 * sem_ch10.adb (Analyze_With_Clause): After analyzed, the entity
32794 corresponding to a private_with must be removed from visibility; it
32795 will be made visible later, just before we analyze the private part of
32797 (Check_Private_Child_Unit): Allow private_with clauses in public
32799 (Install_Siblings): Make visible the private entities of private-withed
32801 (Install_Withed_Unit): Do not install the private withed unit if we
32802 are compiling a package declaration and the Private_With_OK flag was
32803 not set by the caller. These declarations will be installed later,
32804 just before we analyze the private part of the package.
32806 * sem_ch3.adb (Analyze_Object_Declaration): In case of errors detected
32807 during the evaluation of the expression that initializes the object,
32808 decorate it with the expected type to avoid cascade errors.
32811 * sem_ch6.adb (Analyze_Subprogram_Body): If we are compiling a library
32812 subprogram we have to install the private_with clauses after its
32813 specification has been analyzed (as documented in AI-262.TXT).
32815 * sem_ch8.adb (Has_Private_With): New function. Determines if the
32816 current compilation unit has a private with on a given entity.
32817 (Find_Direct_Name): Detect the Beaujolais problem described in
32820 * sem_utils.ads, sem_util.adb (Is_Ancestor_Package): New function. It
32821 provides the functionality of the function Is_Ancestor that was
32822 previously available in sem_ch10. It has been renamed to avoid
32825 * sprint.adb (Sprint_Node_Actual): Print limited_with clauses
32827 2004-05-14 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
32829 * utils.c (build_vms_descriptor): Use SImode pointers.
32831 2004-05-14 Vasiliy Fofanov <fofanov@act-europe.fr>

32985 * trans.c (gnat_stabilize_reference_1): Remove case 'b'.
32987 2004-05-13 Diego Novillo <dnovillo@redhat.com>
32989 Merge from tree-ssa-20020619-branch.
32991 * config-lang.in (boot_language, build_by_default): Set
32993 * utils.c (unchecked_convert): Use OEP_ONLY_CONST.
32994 (max_size): Add static chain op for call_expr.
32996 2004-05-12 Richard Sandiford <rsandifo@redhat.com>

33003 * utils.c (max_size): Use MIN_EXPR to find the minimum value of a
33006 2004-05-10 Doug Rupp <rupp@gnat.com>
33008 * 5qsystem.ads: Remove Short_Address subtype declaration. Moved to
33011 * s-auxdec.ads: Add Short_Address subtype (moved here from System).
33013 * Makefile.in: [VMS]: Add translation for 5qauxdec.ads.
33015 * init.c: [VMS] Macroize LIB$ calls for IA64 and Alpha.
33016 Fixes undefined symbols in IA64 gnatlib.
33018 * 5vinmaop.adb: Reference s-auxdec for Short_Address.
33020 * 5xsystem.ads, 5vsystem.ads: Back out last change (addition of subtype
33021 Short_Address). This will be moved to system.auxdec.
33023 2004-05-10 Thomas Quinot <quinot@act-europe.fr>
33025 * sem_util.adb: Replace test for presence of a node that is always
33026 present with a call to Discard_Node.
33028 * sem_ch10.adb (Analyze_Compilation_Unit): Remove superfluous call to
33029 Analyze on the library unit node after generation of distribution stub
33030 constructs. The call was a no-op because Unit_Node has already been
33031 Analyzed, and the tree fragments for the distribution stubs are
33032 analyzed as they are inserted in Exp_Dist.
33033 Update comment regarding to distribution stubs to reflect that we
33034 do not generate stub in separate files anymore.
33036 * einfo.ads: Clarify the fact that a tagged private type has the
33037 E_Record_Type_With_Private Ekind.
33039 * erroutc.adb: Minor reformatting
33041 * erroutc.ads (Max_Msg_Length): Increase to cover possible larger
33042 values if line length is increased using -gnatyM (noticed during code
33045 * eval_fat.adb: Minor reformatting
33046 Put spaces around exponentiation operator
33048 2004-05-10 Ed Schonberg <schonberg@gnat.com>
33051 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): If prefix
33052 has been rewritten as an explicit dereference, retrieve type of
33053 original node to check for possibly unconstrained record type.
33055 2004-05-10 Ed Schonberg <schonberg@gnat.com>
33057 * exp_ch7.adb (Check_Visibly_Controlled): If given operation is not
33058 overriding, use the operation of the parent unconditionally.
33060 * sem_ch4.adb (Remove_Address_Interpretations): Remove address

33610 whether a pragma All_Calls_Remote applies to the subprogram on which
33612 No functional change is introduced by this revision; the new parameter

34664 resolve links when computing the display names.
34666 2004-03-25 Thomas Quinot <quinot@act-europe.fr>
34668 * sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
34669 attribute reference does not denote a subtype, it can be any
34670 expression that has a classwide type, potentially after an implicit
34671 dereference. In particular, the prefix can be a view conversion for
34672 a classwide type (for which Is_Object_Reference holds), but it can
34673 also be a value conversion for an access-to-classwide type. In the
34674 latter case, there is an implicit dereference, and the original node
34675 for the prefix does not verify Is_Object_Reference.
34677 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
34678 conversion of a discriminant-dependent component of a mutable object
34681 2004-03-25 Ed Schonberg <schonberg@gnat.com>
34683 * freeze.adb (Freeze_Entity): When an inherited subprogram is
34684 inherited, has convention C, and has unconstrained array parameters,
34685 place the corresponding warning on the derived type declaration rather
34686 than the original subprogram.
34688 * sem_ch12.adb (Instantiate_Formal_Subprogram): Set From_Default
34689 indication on renaming declaration, if formal has a box and actual
34692 * sem_ch8.adb (Analyze_Subprogram_Renaming): Use From_Default flag to
34693 determine whether to generate an implicit or explicit reference to
34694 the renamed entity.
34696 * sinfo.ads, sinfo.adb: New flag From_Default, to indicate that a
34697 subprogram renaming comes from a defaulted formal subprogram in an
34700 2004-03-25 Gary Dismukes <dismukes@gnat.com>
34702 * sem_elab.adb (Check_Elab_Call): Refine loop that checks for default
34703 value expressions to ensure that calls within a component definition
34704 will be checked (since those are evaluated during the record type's
34707 2004-03-25 Arnaud Charlet <charlet@act-europe.fr>
34709 * s-tpobop.adb: Code clean up:
34710 (Requeue_Call): Extract from PO_Service_Entries to remove duplicated

34720 * decl.c (gnat_to_gnu_entity, case E_Access_Type): Pass value
34721 of No_Strict_Aliasing to build_pointer_type_for_mode.
34722 * utils.c (update_pointer_to): Walk pointer and ref chains.
34724 2004-03-22 Cyrille Comar <comar@act-europe.fr>
34726 * ali.ads: Fix Comment about Dynamic_Elab.
34728 * gnatls.adb (Output_Unit): Add output of many flags (Dynamic_Elab,
34729 Has_RACW, Is_Generic, etc.)
34730 (Output_Object, Gnatls): Take into account ALI files not attached to
34733 2004-03-22 Vincent Celier <celier@gnat.com>
34735 * gprep.adb: Change all String_Access to Name_Id
34736 (Is_ASCII_Letter): new function
34737 (Double_File_Name_Buffer): New procedure
34738 (Preprocess_Infile_Name): New procedure
34739 (Process_Files): New procedure
34740 (Gnatprep): Check if output and input are existing directories.

34748 2004-03-22 Sergey Rybin <rybin@act-europe.fr>
34750 * scn.adb (Contains): Add check for EOF, is needed for a degenerated
34751 case when the source contains only comments.
34753 2004-03-22 Ed Schonberg <schonberg@gnat.com>
34755 * sem_ch10.adb (Analyze_Compilation_Unit): When generating a
34756 declaration for a child subprogram body that acts as a spec, indicate
34757 that the entity in the declaration needs debugging information.
34759 * sem_ch3.adb (Complete_Private_Subtype): Do not build an underlying
34760 full view if the subtype is created for a constrained record component;
34761 gigi has enough information to construct the record, and there is no
34762 place in the tree for the declaration.
34764 * sem_ch6.adb (Build_Body_To_Inline): Use an internal name without
34765 serial number for the dummy body that is built for analysis, to avoid
34766 inconsistencies in the generation of internal names when compiling
34769 2004-03-22 Thomas Quinot <quinot@act-europe.fr>
34771 * sem_util.adb (Is_Object_Reference): A view conversion denotes an
34774 2004-03-22 GNAT Script <nobody@gnat.com>
34776 * Make-lang.in: Makefile automatically updated
34778 2004-03-21 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
34780 * decl.c (gnat_to_gnu_entity): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.
34781 * trans.c (tree_transform, emit_index_check): Likewise.
34782 * utils.c (build_template): Likewise.
34783 (max_size, convert): Remove handling of WITH_RECORD_EXPR.
34784 (maybe_unconstrained_array, unchecked_convert): Likewise.
34785 * utils2.c (gnat_truthvalue_conversion, build_binary_op): Likewise.
34786 (build_unary_op): Likewise.
34787 (compare_arrays, build_allocator): Use SUBSTITUTE_PLACEHOLDER_IN_EXPR.

34796 * gnat_ug.texi: Add info directory category and entry.
34797 * gnat_ug_unx.texi, gnat_ug_vms.texi, gnat_ug_vxw.texi,
34798 gnat_ug_wnt.texi: Regenerate.
34800 2004-03-19 Arnaud Charlet <charlet@act-europe.fr>
34802 * ada-tree.h: Update copyright notice.
34803 Minor reformatting.
34805 2004-03-19 Olivier Hainque <hainque@act-europe.fr>
34807 * decl.c (gnat_to_gnu_entity, case E_Exception): Handle VMS exceptions
34808 as regular exception objects and not as mere integers representing the
34809 condition code. The latter approach required some dynamics to mask off
34810 severity bits, which did not fit well into the GCC table based model.
34811 (gnat_to_gnu_entity, objects): Don't supply an external name for VMS
34812 exception data objects. We don't it and it would conflict with the other
34813 external symbol we have to generate for such exceptions.
34815 * trans.c (tree_transform, case N_Exception_Handler): Remove part of
34816 the special code for VMS exceptions, since these are now represented
34817 as regular exceptions objects.
34819 2004-03-19 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
34821 * decl.c (debug_no_type_hash): Remove.
34822 (gnat_to_gnu_entity, case E_Array_Type): Don't set and clear it.
34823 * misc.c (LANG_HOOK_HASH_TYPE): Redefine.
34825 2004-03-19 Laurent Guerby <laurent@guerby.net>
34827 * sem_prag.adb (Suppress_Unsuppress_Echeck): use loop instead of
34828 aggregate, allows bootstrap from 3.3 on powerpc-darwin.
34830 2004-03-18 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
34832 * ada-tree.h (TYPE_LEFT_JUSTIFIED_MODULAR_P): Add checking.
34833 (TYPE_CONTAINS_TEMPLATE_P, TYPE_OBJECT_RECORD_TYPE): Likewise.
34834 (TYPE_RM_SIZE_INT): Directly use type.values.
34835 (TREE_LOOP_ID): Clean up check.
34836 * decl.c (gnat_to_gnu_entity, case E_Enumeration_Type): Use
34837 TYPE_VALUES, not TYPE_FIELDS.
34838 * trans.c (convert_with_check): Delay access of bounds of basetype
34839 until sure is numeric.
34841 2004-03-18 Arnaud Charlet <charlet@act-europe.fr>

34847 5vtaprop.adb, 5wtaprop.adb, 7staprop.adb (Finalize_TCB): Use
34848 Specific.Set instead of direct call to e.g pthread_setspecific.
34850 2004-03-18 Thomas Quinot <quinot@act-europe.fr>
34852 * adaint.c: Update comments.
34854 * Makefile.in: set PREFIX_OBJS, SYMLIB, THREADSLIB, and
34855 GNATLIB_SHARED for FreeBSD.
34857 2004-03-18 Jose Ruiz <ruiz@act-europe.fr>
34859 * init.c [VxWorks]: Do not fix the stack size for the environment task.
34860 When needed (stack checking) the stack size is retrieved
34861 from the VxWorks kernel.
34863 * Makefile.in: Flag -nostdinc is required when building the run time
34864 for avoiding looking for files in the base compiler.
34865 Add the VxWorks specific version of the package body for
34866 System.Stack_checking.Operations (5zstchop.adb).
34868 * Make-lang.in: Add the object file for
34869 System.Stack_Checking.Operations.
34871 * Makefile.rtl: Add object file for the package
34872 System.Stack_Checking.Operations.
34874 * s-stchop.ads, s-stchop.adb, 5zstchop.adb: New files.
34876 * s-stache.ads, s-stache.adb: Move the operations related to stack
34877 checking from this package to package System.Stack_Checking.Operations.
34878 This way, stack checking operations are only linked in the final
34879 executable when using the -fstack-check flag.
34881 2004-03-18 Doug Rupp <rupp@gnat.com>
34883 * Makefile.in [VMS]: Handle 64 bit specs (5qsystem.ads, 5xcrtl.ads).
34886 * 5qsystem.ads, 5xcrtl.ads: New files.

34893 (Add_To_Source_Path, Add_To_Object_Path): New procedures, to replace
34894 the procedures Add_To_Path_File.
34895 (Set_Ada_Paths): Accumulate source and object dirs in the tables,
34896 making sure that each directory is present only once and, for object
34897 dirs, when a directory already present is added, the duplicate is
34898 removed and the directory is always put as the last in the table.
34899 Write the path files at the end of these accumulations.
34901 * prj-nmsc.adb (Record_Source): Add source file name in hash table
34902 Files_Htable for all sources.
34904 * prj-proc.adb (Process): Remove restrictions between not directly
34905 related extending projects.

34910 (Find_Sources): Minor speed optimization.
34912 * prj-proc.ads, prj-proc.adb (Check, Recursive_Check, Process): New
34913 parameter Trusted_Mode.
34915 2004-03-18 Sergey Rybin <rybin@act-europe.fr>
34917 * scn.adb (Determine_License): Take into account a degenerated case
34918 when the source contains only comments.
34920 2004-03-18 Ed Schonberg <schonberg@gnat.com>
34922 * sem_warn.adb (Check_References): For a warning on a selected
34923 component that does not come from source, locate an uninitialized
34924 component of the record type to produce a more precise error message.
34926 2004-03-15 Jerome Guitton <guitton@act-europe.fr>
34928 * 3zsoccon.ads: Fix multicast options.
34930 * s-thread.ads: Move unchecked conversion from ATSD_Access to Address
34933 2004-03-15 Robert Dewar <dewar@gnat.com>
34935 * sem_prag.adb: Make sure No_Strict_Aliasing flag is set right when
34936 pragma used for a private type.
34938 * lib-xref.adb (Generate_Reference): Do not generate warning if
34939 reference is in a different unit from the pragma Unreferenced.
34941 * 5vtpopde.adb: Minor reformatting
34942 Fix casing of To_Task_ID
34944 * sem_ch13.adb (Validate_Unchecked_Conversion): Set No_Strict_Aliasing
34945 flag if we have an unchecked conversion to an access type in the same
34948 2004-03-15 Geert Bosch <bosch@gnat.com>
34950 * a-ngcoty.adb (Modulus): In alternate formula for large real or
34951 imaginary parts, use Double precision throughout.
34953 * a-tifiio.adb (Put_Scaled): Remove remaining pragma Debug. Not only
34954 we want to be able to compile run-time with -gnata for testing, but
34955 this may also be instantiated in user code that is compiled with -gnata.
34957 2004-03-15 Olivier Hainque <hainque@act-europe.fr>
34959 * s-stalib.ads (Exception_Code): New type, to represent Import/Export
34960 codes. Having a separate type for this is useful to enforce consistency
34961 throughout the various run-time units.
34962 (Exception_Data): Use Exception_Code for Import_Code.
34964 * s-vmextra.ads, s-vmexta.adb: Use Exception_Code instead of a mix of
34965 Natural and Integer in various places.
34966 (Register_VMS_Exception): Use Base_Code_In to compute the exception code
34967 with the severity bits masked off.
34968 (Register_VMS_Exception): Handle the additional exception data pointer
34971 * raise.c (_GNAT_Exception structure): Remove the handled_by_others
34972 component, now reflected by an exported accessor.
34973 (is_handled_by): New routine to compute whether the propagated
34974 occurrence matches some handler choice specification. Extracted out of
34975 get_action_description_for, and expanded to take care of the VMS
34977 (get_action_description_for): Use is_handled_by instead of an explicit
34978 complex condition to decide if the current choice at hand catches the
34979 propagated occurrence.
34981 * raise.h (Exception_Code): New type for C.
34983 * rtsfind.ads (RE_Id, RE_Unit_Table): Add
34984 System.Standard_Library.Exception_Code, to allow references from the
34985 pragma import/export expander.
34987 * a-exexpr.adb (Is_Handled_By_Others, Language_For, Import_Code_For):
34988 New accessors to allow easy access to GNAT exception data
34990 (GNAT_GCC_Exception record, Propagate_Exception): Get rid of the
34991 redundant Handled_By_Others component, helper for the personality
34992 routine which will now be able to call the appropriate exception data
34995 * cstand.adb (Create_Standard): Adjust the type of the Import_Code
34996 component of Standard_Exception_Type to be the closest possible to
34997 Exception_Code in System.Standard_Library, that we cannot get at this
34998 point. Expand a ??? comment to notify that this type node should
34999 probably be rewritten later on.
35001 * exp_prag.adb (Expand_Pragma_Import_Export_Exception): Adjust the
35002 registration call to include a pointer to the exception object in the
35005 * init.c (__gnat_error_handler): Use Exception_Code and Base_Code_In
35006 instead of int and explicit bitmasks.
35008 2004-03-15 Vincent Celier <celier@gnat.com>
35010 * vms_data.ads: Add new GNAT BIND qualifier /STATIC. Makes /NOSHARED
35011 equivalent to /STATIC and /NOSTATIC equivalent to /SHARED.
35013 * a-tasatt.adb (To_Access_Code): Remove this UC instantiation, no
35014 longer needed now that it is in the spec of
35015 System.Tasking.Task_Attributes.
35017 * adaint.h, adaint.c: (__gnat_create_output_file): New function
35019 * gnatcmd.adb: Fix bug introduced in previous rev: /= instead of =
35021 * g-os_lib.ads, g-os_lib.adb (Create_Output_Text_File): New function.
35023 * make.adb (Gnatmake): Do not check the executable suffix; it is being
35024 taken care of in Scan_Make_Arg.
35025 (Scan_Make_Arg): Add the executable suffix only if the argument
35026 following -o, in canonical case, does not end with the executable
35027 suffix. When in verbose mode and executable file name does not end
35028 with executable suffix, output the executable name, in canonical case.
35030 * s-tataat.ads (Access_Dummy_Wrapper): Add pragma No_Strict_Aliasing
35031 to avoid warnings when instantiating Ada.Task_Attributes.
35034 * mlib-prj.adb (Process_Imported_Libraries): Get the imported libraries
35035 in the correct order.
35037 * prj-makr.adb (Process_Directory): No longer use GNAT.Expect, but
35038 redirect standard output and error to a file for the invocation of the
35039 compiler, then read the file.
35041 * prj-nmsc.adb (Find_Sources): Use the Display_Value for each
35042 directory, instead of the Value.
35043 (Find_Source_Dirs): Remove useless code & comments.
35045 2004-03-15 Ed Schonberg <schonberg@gnat.com>
35047 * exp_ch3.adb (Freeze_Record_Type): If a primitive operation of a
35048 tagged type is inherited, and the parent operation is not frozen yet,
35049 force generation of a freeze node for the inherited operation, so the
35050 corresponding dispatch entry is properly initialized.
35051 (Make_Predefined_Primitive_Specs): Check that return type is Boolean
35052 when looking for user-defined equality operation.
35054 * exp_ch4.adb (Expand_Composite_Equality): Check that return type is
35055 boolean when locating primitive equality of tagged component.
35057 * exp_ch5.adb (Expand_Assign_Array): If the left-hand side is a
35058 bit-aligned field and the right-hand side a string literal, introduce
35059 a temporary before expanding assignment into a loop.
35061 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Copy expression for
35062 priority in full, to ensure that any expanded subepxressions of it are
35063 elaborated in the scope of the init_proc.
35065 * exp_prag.adb (Expand_Pragma_Import): Search for initialization call
35066 after object declaration, skipping over code that may have been
35067 generated for validity checks.
35069 * sem_ch12.adb (Validate_Private_Type_Instance): If type has unknown
35070 discriminants, ignore the known discriminants of its full view, if
35071 any, to check legality.
35073 * sem_ch3.adb (Complete_Private_Subtype): Do not create constrained
35074 component if type has unknown discriminants.
35075 (Analyze_Private_Extension_Declaration): Discriminant constraint is
35076 null if type has unknown discriminants.
35078 * sem_ch6.adb (Analyze_Generic_Subprogram_Body): Generate reference
35079 for end label when present.
35081 * s-fileio.adb (Open): When called with a C_Stream, use given name for
35082 temporary file, rather than an empty string.
35084 2004-03-15 Ed Falis <falis@gnat.com>
35086 * s-thread.adb: Removed, no longer used.
35088 2004-03-15 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
35090 * decl.c (target.h): Now include.

35106 * 5ztpopsp.adb, 56tpopsp.adb: Fix spelling of Task_ID.
35108 * exp_ch4.adb (Expand_N_Indexed_Component): Do not call
35109 Insert_Dereference_Action when rewriting an implicit dereference into
35110 an explicit one, this will be taken care of during expansion of the
35111 explicit dereference.
35112 (Expand_N_Slice): Same. Always do the rewriting, even for the case
35113 of non-packed slices, since the dereference action generated by
35114 expansion of the explicit dereference is needed in any case.
35115 (Expand_N_Selected_Component): When rewriting an implicit dereference,
35116 analyze and resolve the rewritten explicit dereference so it is seen
35118 (Insert_Dereference_Action): This procedure is now called only for the
35119 expansion of an N_Explcit_Dereference_Node. Do insert a check even for
35120 dereferences that do not come from source (including explicit
35121 dereferences resulting from rewriting implicit ones), but do not
35122 recursively insert a check for the dereference nodes contained within
35124 (Insert_Dereference_Action): Clarify and correct comment.

35164 * sem_ch13.adb: Generate validate unchecked conversion nodes for gcc.
35166 * sem_ch3.adb: Set No_Strict_Aliasing flag if config pragma set.
35168 * sem_prag.adb: Implement pragma No_Strict_Aliasing.
35170 * sinfo.ads: Remove obsolete comment on validate unchecked conversion

36343 2004-01-12 Ed Schonberg <schonberg@gnat.com>
36345 * lib-xref.adb (Get_Type_Reference): If the type is the subtype entity
36346 generated to rename a generic actual, go to the actual itself, the
36347 subtype is not a user-visible entity.
36349 * sem_ch7.adb (Uninstall_Declarations): If an entity in the visible

36462 * exp_ch5.adb (Expand_Assign_Array): Avoid assumption that
36463 N_String_Literal node always references an E_String_Literal_Subtype
36464 entity. This may not be true in the future.
36465 (Possible_Bit_Aligned_Component): Move processing of
36466 Component_May_Be_Bit_Aligned from exp_ch5 to exp_util
36468 * exp_ch6.adb (Expand_Thread_Body): Pick up

36473 (Type_May_Have_Bit_Aligned_Components): New function.

36513 * sem_elab.adb (Check_A_Call): Rewrite to avoid trying to put
36514 ineffective elaborate all pragmas on non-visible packages (this
36515 happened when a renamed subprogram was called). Now the elaborate all
36516 always goes on the package containing the renaming rather than the one
36517 containing the renamed subprogram.
36519 * sem_elim.ads, sem_elim.adb (Eliminate_Error_Msg): New procedure
36520 (Process_Eliminate_Pragma): Add parameter to capture pragma location.

36545 * make.adb (Gnatmake): Special process for files to compile/check when
36546 -B is specified. Fail when there are only foreign mains in attribute
36547 Main of the project file and -B is not specified. Do not skip bind/link

36581 * Makefile.in: Install ali files using INSTALL_DATA_DATE to preserve
36582 all attributes, including read-only attribute.

36587 library naming scheme.

36618 * sem_ch4.adb (Analyze_Allocator): Check restriction on dynamic
36619 protected objects when allocator has a subtype indication, not a

36621 checked when limited aggregates are implemented.

36624 pure, emit warning.

36790 2003-12-08 Jerome Guitton <guitton@act-europe.fr>
36792 * 5ytiitho.adb, 5zthrini.adb, 5ztiitho.adb, i-vthrea.adb,
36793 i-vthrea.ads, s-tpae65.adb, s-tpae65.ads: Cleanup: Remove a bunch of
36796 * Makefile.in: (rts-ravenscar): Generate an empty libgnat.a.
36799 2003-12-08 Robert Dewar <dewar@gnat.com>
36801 * 7sintman.adb: Minor reformatting
36803 * bindgen.adb: Configurable_Run_Time mode no longer suppresses the
36804 standard linker options to get standard libraries linked. We now plan
36805 to provide dummy versions of these libraries to match the appropriate
36806 configurable run-time (e.g. if a library is not needed at all, provide
36807 a dummy empty library).
36809 * targparm.ads: Configurable_Run_Time mode no longer affects linker
36810 options (-L parameters and standard libraries). What we plan to do is
36811 to provide dummy libraries where the libraries are not required.
36813 * gnatbind.adb: Minor comment improvement
36815 2003-12-08 Javier Miranda <miranda@gnat.com>
36817 * exp_aggr.adb (Build_Record_Aggr_Code): Do not remove the expanded
36818 aggregate in the parent. Otherwise constants with limited aggregates
36819 are not supported. Add new formal to pass the component type (Ctype).
36820 It is required to call the corresponding IP subprogram in case of
36821 default initialized components.
36822 (Gen_Assign): In case of default-initialized component, generate a
36823 call to the IP subprogram associated with the component.
36824 (Build_Record_Aggr_Code): Remove the aggregate from the parent in case
36825 of aggregate with default initialized components.
36826 (Has_Default_Init_Comps): Improve implementation to recursively check
36827 all the present expressions.
36829 * exp_ch3.ads, exp_ch3.adb (Build_Initialization_Call): Add new formal
36830 to indicate that the initialization call corresponds to a
36831 default-initialized component of an aggregate.
36832 In case of default initialized aggregate with tasks this parameter is
36833 used to generate a null string (this is just a workaround that must be
36834 improved later). In case of discriminants, this parameter is used to
36835 generate a selected component node that gives access to the discriminant
36838 * exp_ch9.ads, exp_ch9.adb (Build_Task_Allocate_Block_With_Stmts): New
36839 subprogram, based on Build_Task_Allocate_Block, but adapted to expand
36840 allocated aggregates with default-initialized components.
36842 * par-ch4.adb (P_Aggregate_Or_Paren_Expr): Improve error message if
36843 the box notation is used in positional aggregates.

36885 Process nodes N_Comment.
36887 * prj-tree.ads, prj-tree.adb (Default_Project_Node): If it is a node
36888 without comments and there are some comments, set the flag
36889 Unkept_Comments to True.
36890 (Scan): If there are comments, set the flag Unkept_Comments to True and
36891 clear the comments.

36922 (Set_Comment_As_Token): New procedure
36924 * sinput-p.adb: Update Copyright notice
36925 (Source_File_Is_Subunit): Call Prj.Err.Scanner.Scan instead of Prj.Scan

36928 2003-12-08 Javier Miranda <miranda@gnat.com>
36930 * sem_aggr.adb: Add dependence on Exp_Tss package
36931 Correct typo in comment
36932 (Resolve_Aggregate): In case of array aggregates set the estimated
36933 type of the aggregate before calling resolve. This is needed to know
36934 the name of the corresponding IP in case of limited array aggregates.
36935 (Resolve_Array_Aggregate): Delay the resolution to the expansion phase
36936 in case of default initialized array components.
36938 * sem_ch12.adb (Analyze_Formal_Object_Declaration): Allow limited

36954 * Make-lang.in: Makefile automatically updated
36956 2003-12-08 Arnaud Charlet <charlet@act-europe.fr>
36958 * sinfo.h, einfo.h, nmake.ads, nmake.adb, treeprs.ads: Removed, since
36959 they are automatically generated by Make-lang.in and cause nothing but
36960 maintenance troubles.
36962 2003-12-05 Thomas Quinot <quinot@act-europe.fr>
36964 * 3ssoliop.ads: Fix comment (this is the Solaris, not the UnixWare,

36978 * 7sintman.adb (elaboration): Set SA_SIGINFO in the sigaction flags,
36979 to ensure that the kernel fills in the interrupted context structure
36980 before calling a signal handler, which is necessary to be able to
36981 unwind past it. Update the copyright notice.
36983 2003-12-05 Jerome Guitton <guitton@act-europe.fr>
36985 * a-elchha.ads: New file.
36987 * a-elchha.adb: New default last chance handler. Contents taken from
36988 Ada.Exceptions.Exception_Traces.Unhandled_Exception_Terminate.

37070 included in HIE_NONE_TARGET_PAIRS.
37072 2003-12-03 Ed Schonberg <schonberg@gnat.com>
37075 (Legal_Formal_Attribute): Attribute is legal in an inlined body, as it
37076 is legal in an instance, because legality is cheched in the template.

37097 * a-except.adb (Raise_Current_Excep): Add a pragma Inspection_Point,
37098 so that the debugger can reliably access the value of the parameter,

37234 Add to Unblocked_Signal_Mask the set of signals that are in
37238 Adding a check to see whether the Interrupt_ID we want to unmask is in
37239 the range of Keep_Unmasked (in procedure Interrupt_Self_Process). The
37240 reason is that the index type of the Keep_Unmasked array is not always
37241 Interrupt_ID; it may be a subtype of Interrupt_ID.
37243 2003-11-24 Gary Dismukes <dismukes@gnat.com>
37246 (Remove_Side_Effects): Condition constantness of object created for a

37288 2003-11-24 Sergey Rybin <rybin@act-europe.fr>
37290 * opt.adb (Tree_Write): Gnat_Version_String is now a function, so we
37291 can not use it as before (that is, as a variable) when dumping it into

41032 (Determine_Range): Make sure Hbound is initialized. It looks as though
41033 there could be a real problem here with an uninitialized reference
41034 to Hbound, but no actual example of failure has been found.
41036 2001-12-17 Laurent Pautet <pautet@gnat.com>
41039 Fix comment of Shutdown_Socket and Close_Socket. These functions
41040 should not fail silently because if they are called twice, this
41041 probably means that there is a race condition in the user program.
41042 Anyway, this behaviour is consistent with the rest of this unit.
41043 When an error occurs, an exception is raised with the error message
41044 as exception message.

41196 (Associated_Node): Documentation explicitly mentions attribute
41197 reference nodes, since this field is used in such nodes.

42378 instead of the previous simple checksum algorithm.
42379 (Time_Stamp_Mismatch): use CRC_Match for comparison.
42380 (Set_Source_Table): idem.
42383 (Get_File_Checksum): renamed Get_File_CRC as now we compute CRC
42384 instead of simple checksum.
42385 (CRC_Match): new function.
42386 (CRC_Error): new constant.
42388 * ali.adb (Scan_ALI): rename variable Chk to CRC as we are handling
42389 a CRC now and not a simple checksum. A CRC uses lower-case hex
42390 letters, fixes ambiguity in parsing.
42392 * ali.ads (Sdep_Record.Checksum): renamed Sdep_Record.CRC as this
42393 is what this variable will store.
42395 * bcheck.adb: Change reference to chechsum in comments by CRC.
42396 (Check_Consistency): Rename Get_File_Checksum to Get_File_CRC.
42397 rename All_Checksum_Match to All_CRC_Match. Change due to API
42398 renaming since now GNAT does not use a simple checksum but a
42399 CRC using GNAT.CRC32.
42401 * gnatls.adb: Rename Checksum to CRC in many places, we use a CRC
42402 now and not anymore a simple checksum.

42441 * types.adb (Hex): Use lowercase for the letter part.
42443 * types.ads (Get_Hex_String): Returns the hexadecimal representation
42444 for a word. This is currently used only for CRC. In previous version,
42445 the checksum was using a representation with all letter being
42446 upper-case. With the new implementation (using CRC) we do not remove
42447 the 32th bit of the CRC, so we can have an upper-case starting letter
42448 in the CRC. This is not possible to parse in Scan_ALI (ali.adb).
42449 It is ambigous since the CRC was optional and could be followed by
42450 options like EB, EE. So now this routines uses lower-case letter for
42451 the hexadecimal representation. Strange enough only lower case letters
42452 where checked in Scan_ALI (even if this was not a possible case).
42454 * gnatvsn.ads (Library_Version): changed to 3.15a.
42456 * s-crc32.ads: Initial version from GNAT.CRC32. This is the version
42459 * s-crc32.adb: Initial version from GNAT.CRC32. This is the version

42463 Add 2001 to copyright notice
42464 (Accumulate_Checksum): Modify to use System.CRC32.
42466 * ali-util.ads: Redo changes of previous revision to continue to use
42467 the word Checksum. Add 2001 to copyright notice.
