264 outside of a subprogram body. This case was previously handled during

266 we continued freezeing entities outside of the subprogram. Now, when
267 climbing the parents chain to locate the correct placement for the
268 freezeing node, we check if the entity can be frozen and only when no

281 Its code is basically the previous version of this routine but extended
282 with an additional parameter which is used to specify if during
283 preanalysis we are allowed to freeze entities. If the new parameter is
284 True then the subtree root node is marked as Must_Not_Freeze and no
285 entities are frozen during preanalysis.
286 (Preanalyze_And_Resolve): Invokes the internal version of
287 Preanalyze_And_Resolve without entity freezing.

324 transient blocks nested in a block that do not manage the secondary
325 stack and are located within a loop.
327 2018-07-17 Ed Schonberg <schonberg@adacore.com>
329 * sem_util.adb (Enclosing_Subprogram): Protected entries and task
330 entries must be treated separately: task entries are within the

1204 as reachable from outside the current unit. This includes entry bodies
1205 and protected operations.
1207 2018-05-31 Ed Schonberg <schonberg@adacore.com>
1209 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
1210 Convert all operands of the generated code to Standard.Unsigned, to
1211 prevent spurious visibility errors. This is needed when the generated
1212 expansion involves a modular index type of an array type, and the index
1213 type is not immediately visible.

1276 (Start_Search): Modify to use Start_Search_Internal
1277 (Start_Search_Internal): Add to break out an extra flag for searching

1350 comment about the memset case.
1352 2018-05-30 Bob Duff <duff@adacore.com>
1354 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1355 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1356 We need to analyze it as part of analyzing the block, so that if the
1357 call to Element that initializes Elmt_Decl returns on the secondary
1358 stack, the block will ss_mark/ss_release. This block is inside the
1359 loop; we don't want to leak memory until the loop exits. The purpose
1360 of analyzing Elmt_Decl first was to catch the error of modifying it,
1361 which is illegal because it's a loop parameter. The above causes us to
1362 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1363 it on the Element entity, so we end up with an E_Variable node with the
1365 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1366 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1367 parameter not allowed" error if Is_Loop_Parameter.
1368 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
1369 trigger the call to Diagnose_Non_Variable_Lhs.
1371 2018-05-30 Arnaud Charlet <charlet@adacore.com>
1373 * checks.adb (Apply_Scalar_Range_Check):
1374 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
1375 range values for System.Priority in CodePeer mode since the actual
1376 target compiler may provide a wider range.
1378 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1380 * exp_unst.adb: Search specification of main unit as well, for
1383 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1385 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1386 a package body that is a compilation unit may contain blocks that
1387 declare local subprograms. In Subprogram_Unnesting Mode such
1388 subprograms must be handled as nested inside the (implicit) elaboration
1389 procedure that executes that statement part. To handle properly uplevel
1390 references we construct that subprogram explicitly, to contain blocks
1391 and inner subprograms, The statement part of the compilation unit
1392 becomes a call to this subprogram. This is only done if blocks are
1393 present in the statement list of the body.
1395 2018-05-30 Bob Duff <duff@adacore.com>
1397 * exp_ch7.adb: Minor comment fix.

1405 for subprogram instantiations to enter callable entity into Subp table.

1412 package to account for the new secondary stack structure. Add types
1413 and subprograms for testing purposes. Add several documentation

1464 tagged type. In such case, collecting the list of primitives we may
1465 find two equality primitives: one associated with the untagged private

1700 references, examine index expressions or associated expressions as well
1701 to record uplevel references.

1704 of actual have uplevel references.
1706 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1708 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus

1721 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1722 discriminant constraints as well.
1723 (Visit_Node): For a selected component, check type of prefix, as is
1724 done for indexed components and slices.
1726 2018-05-28 Javier Miranda <miranda@adacore.com>
1728 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1729 value when converting a float value to a fixed-point value. This is
1730 required for CCG because it handles fixed-point types by means of
1731 unsigned integer type variables. The range check is now performed using
1732 the integer value stored in this temporary.
1734 2018-05-28 Yannick Moy <moy@adacore.com>

1757 component type, do not expand array equality using the unconstrained
1758 base type, except for the case where the bounds of the type depend on a
1761 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1763 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1764 access-to-subprogram types, to indicate that an indirect call through
1765 such a type requires an activation record when compiling for LLVM.
1766 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1768 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1770 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1771 when bounds of fixed type are static, to remove some spuerfluous
1772 implicit conversions and provide an accurate result when converting
1773 back and forth between the fixed point type and a floating point type.
1775 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1777 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1780 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1782 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1783 replaced, if any; all callers changed.
1784 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1785 constant with private view so we take the address of that entity.
1786 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1787 any; all callers changed. Handle N_Indexed_Component like
1788 N_Attribute_Reference. Add N_Type_Conversion case.
1789 (Visit_Node): Indexed references can be uplevel if the type isn't
1791 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1792 been relocated, set first_named pointer in original node as well.
1794 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1796 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1797 association with a range or a set of discrete choices, rather than
1798 relocating the node. This avoids inconsistencies in the tree when
1799 handling nested subprograms with uplevel references for LLVM.

1854 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1855 the declarations of single concurrent types because they fall in the
1856 category of full type and object declarations.

1865 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1866 includes a call to function to which it applies. This may mean an
1867 omission of an attribute reference 'Result, in particular if the
1868 function is pqrameterless.
1870 2018-05-28 Justin Squirek <squirek@adacore.com>

1877 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1878 GNATprove mode, as the order of resolution (low then high) means that

1884 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1885 end with the linker section, if any.
1886 (List_Entities): Do not output the linker section for record types,
1887 array types and variables.
1888 (Print_Expr): Factor out common processing for unary operators and
1889 special values. Adjust and reorder the various cases.
1890 (List_Object_Info): End with the linker section, if any.
1891 (List_Record_Info): Likewise.
1892 (List_Type_Info): Do not start with a blank line.
1894 2018-05-25 Nicolas Roche <roche@adacore.com>
1896 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1897 that the result will be either -infinite or +infinite.
1899 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1901 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

1903 Expand range of type to match the address space of the target.
1904 (Task_Storage_Size): Remove unused type.
1906 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1908 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1909 of a fixed point type and the parent is a multiplying operation,
1910 resolve the operand with its own type because the context will impose a
1911 resulting type on the result of the multiplication by means of
1912 approriate conversion.
1914 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1916 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1917 the in-place initialization aggregate created for pragmas
1918 Initialize_Scalars or Normalize_Scalars is performed with checks
1921 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1923 * exp_aggr.adb (Convert_To_Positional): Bump default for
1924 Max_Others_Replicate to 32. Update comments.
1925 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1926 (No_File_Info_Cache): Initialize separately.

1931 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
1932 test when the left operand is a class-wide interface and the right

1937 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1939 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated

1945 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1947 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1948 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1949 into three distring cases rather than in one loop which attempts to
1950 handle all three cases. This rewrite eliminates an issue where the last
1951 frame of the stack cannot be freed, thus causing the memory range of a
1952 new frame to approach the overflow point of the memory index type.
1953 Since the overflow is logically treated as a
1954 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1955 (SS_Allocate_Static): New routine. The routine factorizes the static
1956 secondary stack-related code from the former SS_Allocate.
1958 2018-05-25 Sergey Rybin <rybin@adacore.com>
1960 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1961 option for gnatelim.
1963 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1965 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1966 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1967 is created when the proper body of the stub is analyzed.
1968 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1969 is the proper body of a subunit, the cloned body must be inserted in
1970 the declarative list that contains the stub.
1972 2018-05-25 Justin Squirek <squirek@adacore.com>
1974 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1975 generate code for 6.5(8-10) so that we don't get an assertion error
1976 when dealing with an incomplete return type.
1978 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1980 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1981 carrying very large strings.

2007 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2009 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2010 Validate_Derived_Type_Instance, to verify that all interfaces
2011 implemented by the formal type are also implemented by the actual. The
2012 verification is complicated when an interface of the formal is declared
2013 in a generic unit and the actual is declared in an instance of it.
2014 There is currently no mechanism to relate an interface declared within
2015 a generic to the corresponding interface in an instance, so we must
2016 traverse the list of interfaces of the actual, looking for a name
2017 match, and verifying that that interface is declared in an instance.
2019 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
2021 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
2022 assertions; replace function versions of Next_Formal/Next_Actual with
2023 their procedural versions (which are more concise).

3253 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
3254 delegate the secondary stack management when there is no suitable
3255 transient context, and the transient scope was intended to manage the

3257 transient scope creation logic by special casing assignment statements
3258 of controlled components for type initialization procedures.
3259 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
3260 the comment on usage.
3261 (Find_Transient_Context): Change the initinte loop into a while loop.

3267 routine Find_Transient_Context.
3268 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly

3473 suitable construct to wrap, and the transient scope was intended to
3474 manage the secondary stack.

3489 actions are required by utilizing predicate Needs_Finalization rather
3491 (Resolve_Call): Type initialization procedures can now utilize
3492 transient scopes to manage the secondary stack, thus preventing leaks
3493 during initialization. Remove the previous kludgy algorithm which
3494 attempts to manage the secondary stack at the object creation site.

3553 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3555 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
3556 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
3557 (File_Type): Add Default_Initial_Condition aspect.
3559 2018-01-11 Pascal Obry <obry@adacore.com>
3561 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
3563 2018-01-11 Bob Duff <duff@adacore.com>
3565 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3566 to match what the Libadalang-based version does.
3567 * doc/gnat_ugn/about_this_guide.rst: Update reference.
3569 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3571 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3572 if it contains at least one component declaration employing a function
3573 call returning on the secondary stack.
3575 2018-01-11 Yannick Moy <moy@adacore.com>
3577 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
3578 Update description of restriction SPARK_05 with SPARK 2014.

3585 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3587 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
3588 sem_res.adb, sem_util.adb: Minor reformatting.
3590 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3592 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3593 has a delayed aspect which must be processed at the point the type is
3594 frozen. This mimics what is done when the predicate is provided by a
3597 2018-01-11 Doug Rupp <rupp@adacore.com>
3599 * init.c (vxworks): Add macro checks for __aarch64__.
3601 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3603 * exp_util.adb (Add_Failure_Expression): New routine.
3604 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
3605 * sem_util.adb (Is_Current_Instance): Code cleanup.
3607 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3609 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
3610 Default_Sec_Stack_Size.
3611 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3612 limit check so that the integer index does not overflow. Check the
3613 dynamic stack allocation does not cause the secondary stack pointer to
3615 (SS_Info): Align colons.
3616 (SS_Init): Cover the case when bootstraping with an old compiler that
3617 does not set Default_SS_Size.
3619 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3621 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3622 legality of an inherited operation that may require overriding, ignore
3623 primitive_wrappers that correspond to explicit operations that override
3624 an interface primitive.
3625 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3626 operation to which the class-wide expression applies is a protected op.
3627 with a primitive_wrapper, verify that the updated inherited expression
3628 does not contain an internal call to a protected function. This
3629 completes the implementation of AI12-0166.
3631 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3633 * ali.adb: Document the remaining letters available for ALI lines.
3634 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3635 * ali.ads: Update type With_Record. Field
3636 Implicit_With_From_Instantiation is no longer in use. Add field
3638 * csinfo.adb (CSinfo): Remove the setup for attribute
3639 Implicit_With_From_Instantiation.
3640 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3641 either implicitly or explicitly withed.
3642 (Is_Implicit_With_Clause): New routine.
3643 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3644 confusion with the with clause attribute by the same name.
3645 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3646 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3647 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3648 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3650 (Implicit_With_On_Parent): Mark the with clause as generated for a
3652 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3653 instantiation are no longer marked as Implicit_With_From_Instantiation
3654 because they are already marked as implicit.
3655 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3656 which marks implicit with clauses as related to an instantiation.
3657 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3658 (Parent_With): New routine.
3659 (Set_Implicit_With_From_Instantiation): Removed.
3660 (Set_Parent_With): New routine.
3661 * sinfo.ads: Update the documentation of attribute Implicit_With.
3662 Remove attribute Implicit_With_From_Instantiation along with
3663 occurrences in nodes. Add attribute Parent_With along with occurrences
3665 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
3666 (Parent_With): New routine along with pragma Inline.
3667 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
3668 (Set_Parent_With): New routine along with pragma Inline.
3670 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3672 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3673 entity when the enclosing construct is a body.
3675 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3677 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3678 Secondary_Stack_Size handling as a pragma is now generated for the
3679 corresponding aspect instead of an attribute. Pragma expression is
3680 relocated instead of evaluated. Discriminant of the corresponding
3681 record type is referenced rather than the type discriminant.
3682 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3683 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3684 * sem_ch13.adb (Analyze_One_Aspect): Transform
3685 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3686 because the attribute does not have visibility on a task type's
3687 discriminants when the type's definition is expanded.
3688 (Analyze_Attribute_Definition_Clause): Remove handling of
3689 Attribute_Secondary_Stack_Size.
3690 * snames.adb-tmpl, snames.ads-tmpl: Remove
3691 Attribute_Secondary_Stack_Size, no longer used.
3693 2018-01-11 Justin Squirek <squirek@adacore.com>
3695 * sem_ch8.adb: Minor comment fix.
3697 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3699 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3700 individual action because the action may denote a complex expression,
3701 such as a case statement, which in turn may contain additional
3704 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3706 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3707 analysis on a copy of the expression with a copy of the index variable,
3708 because full expansion will rewrite construct into a loop with the
3709 original loop variable.
3710 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3711 expression is an iterated component association. Full analysis takes
3712 place when construct is rewritten as a loop.
3713 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3714 is not safe for in-place assignment.
3715 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3716 entity with no homonym and no other entity in the scope.
3718 2018-01-11 Justin Squirek <squirek@adacore.com>
3720 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3721 message to be printed on the pragma argument identifier.
3723 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3725 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3726 entity of the generated invariant procedure in order to construct a
3727 proper entity chain.
3729 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3731 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3734 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3736 * einfo.ads, einfo.adb (Activation_Record_Component,
3737 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3738 Allow E_Discriminant.
3740 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3742 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3743 for atomic access once the component size is taken into account and
3744 also do it if the component type is Atomic or Volatile_Full_Access.
3746 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3748 * gnatvsn.ads: Bump copyright year.
