375 2017-09-08 Yannick Moy <moy@adacore.com>
377 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
378 return the entity associated with the call.
379 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
380 Replace the internal Get_Function_Id with the new
381 Sem_Aux.Get_Called_Entity.
382 (Iterate_Call_Parameters): New
383 procedure to iterate on formals and actuals at the same time.
384 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
385 Set SPARK_Mode from spec when set, for analysis
386 of instance. Restore after analysis of instance.
387 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
388 set, for analysis of body instance. Restored automatically at
389 the end of the subprogram.
390 * gnat1drv.adb (Adjust_Global_Switches): Set
391 Check_Validity_Of_Parameters to False in GNATprove mode.
392 * opt.ads (Check_Validity_Of_Parameters): Document switch to
395 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
397 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
398 (New_Copy_Tree): ...there. Reset the hash tables only if they
399 were used in the previous invocation.
400 * s-htable.adb: Fix typo.
402 2017-09-08 Bob Duff <duff@adacore.com>
404 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
406 2017-09-08 Arnaud Charlet <charlet@adacore.com>

412 * sprint.adb (Write_Corresponding_Source): Ignore if there is
413 no current source file.
414 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
415 Print something helpful in case N is invalid.
416 * sprint.ads: Minor comment fix.
418 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
420 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
423 2017-09-08 Bob Duff <duff@adacore.com>
425 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
426 Ada_2020, along the same lines as the other Ada version pragmas.
428 2017-09-08 Gary Dismukes <dismukes@adacore.com>
430 * sem_ch12.adb: Minor typo fixes and reformatting.
432 2017-09-08 Yannick Moy <moy@adacore.com>
434 * sem_aggr.adb (Resolve_Record_Aggregate):
435 Rewrite bounds of aggregate subexpressions which may depend on
436 discriminants of the enclosing aggregate.
438 2017-09-08 Yannick Moy <moy@adacore.com>
440 * sem_ch5.adb: Prevent assertion failure on illegal code.
442 2017-09-08 Yannick Moy <moy@adacore.com>
444 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
445 calling Renamed_Entity on an entity which cannot be a renaming.
447 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
449 * exp_aggr.adb: Add with & use clause for Urealp.
450 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
451 elementary types instead of just discrete types.
452 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
453 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
454 Be prepared for the FP zero value in the memset case. Add small
457 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
459 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
462 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
464 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
465 of New_Copy because the latter leaves the syntactic structure of
466 the tree inconsistent (a child is accessible through two parents)
467 and prevents proper replication of itypes by subsequent calls
469 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
470 New_Copy because the latter leaves the syntactic structure of the
471 tree inconsistent (a child is accessible through two parents)
472 and prevents proper replication of itypes by subsequent calls
474 * sem_util.adb (In_Subtree): New routine.
475 (New_Copy_Tree): Reimplemented.

479 2017-09-08 Ed Schonberg <schonberg@adacore.com>
481 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
482 for aspect Default_Value is a static scalar value, but it does
483 not freeze the type. Yhis allows for subsequent representation
484 clauses for the type.
486 2017-09-08 Javier Miranda <miranda@adacore.com>
488 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
489 not add entries into the undefined reference table when we are
490 compiling with errors ignored.
492 2017-09-08 Ed Schonberg <schonberg@adacore.com>
494 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
495 check if the instance is within an enclosing instance body. The
496 formal package was legal in the enclosing generic, and is
497 legal in the enclosing instantiation. This optimisation may be
498 applicable elsewhere, and it also removes spurious errors that
499 may arise with on-the-fly processing of instantiations that
500 contain Inline_Always subprograms.
502 2017-09-08 Vincent Celier <celier@adacore.com>
504 * gnatcmd.adb: Disregard empty argument of GNAT driver.
506 2017-09-08 Justin Squirek <squirek@adacore.com>
508 * checks.adb (Insert_Valid_Check): Manually decorate
509 the generated temporary for range valdity checks.
511 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
513 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
515 2017-09-08 Justin Squirek <squirek@adacore.com>
517 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
518 case to handle underscore flags.
519 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
520 new procedure to handle underscores.
522 2017-09-08 Javier Miranda <miranda@adacore.com>
524 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
525 divisions with fixed point results to avoid generating twice
526 the runtime check on divide by zero.
527 * checks.adb (Apply_Divide_Checks): Ensure that operands are
528 not evaluated twice (once for their runtime checks and once for
529 their regular computation).
531 2017-09-08 Yannick Moy <moy@adacore.com>
533 * sem_prag.adb (Analyze_Part_Of): Add missing
534 return statements after issuing errors. Add detection of
535 out-of-order item and single concurrent type.

679 exceptions instead of crashes. Check for absurdly long strings
680 and empty strings. Empty strings cause trouble because they can
681 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
682 be empty, which causes an array index out of bounds.

929 a loop specification that is a subtype indication whose type mark
930 is a type with a static predicate, inherit predicate function,
931 used to build case statement for rewritten loop.

1035 decrement Warnings_Treated_As_Errors. This is called before
1036 Warnings_Treated_As_Errors has been incremented to account for
1037 this warning. Decrementing it here can lead to negative values
1038 of Warnings_Treated_As_Errors, raising Constraint_Error in
1039 checks-on builds, and causing the compiler to return an error
1040 code in checks-off builds.
1042 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1044 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
1045 entities of named concurrent types as Ref_Id and not of anonymous
1046 concurrent objects (because callers already know when a conversion
1047 is necessary and can easily do it); also, do not expect protected
1048 types or protected objects as Context_Id (because no flow-related
1049 SPARK pragmas are attached there); reflect these changes in a
1050 more precise comment.

1063 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
1064 for compatibility of component types of formal and actual in an
1065 instantiation of a child unit, when the component type of the
1066 formal is itself a formal of an enclosing generic.
1068 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1070 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
1071 sem_prag.adb to make it available for GNATprove; for concurrent
1072 types replace custom scope climbing with Scope_Same_Or_Within; for
1073 single concurrent objects add scope climbing (with Scope_Within),
1074 which was not there (that's the primary semantic change of this
1075 commit); also, when comparing a single concurrent object with
1076 its corresponding concurrent type rely on equality of types,
1077 not of objects (because that's simpler to code).
1078 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
1079 (Analyze_Global_Item): adjust special-casing of references to the
1080 current instance of a concurrent unit in the Global contracts
1081 of task types and single tasks objects; similar for references
1082 in the protected operations and entries of protected types and
1083 single protected objects (in all these cases the current instance
1084 behaves as an implicit parameter and must not be mentioned in
1085 the Global contract).

1098 local to the child unit.

1159 2017-09-08 Bob Duff <duff@adacore.com>
1161 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
1162 the subunit case. It's still OK to set it in the "missing subunits"

1166 2017-09-08 Bob Duff <duff@adacore.com>
1168 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
1169 unclear why this didn't cause a warning.
1170 * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
1171 pragmas. It's unclear why this didn't cause an error.

1207 * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
1208 the placement of a primitive operation O that renames an operation
1209 R declared in an inner package, and which is thus not a primitive
1210 of the dispatching type of O. In this case O is a new primitive

1231 * sem_ch12.adb (Check_Generic_Parent): New procedure within
1232 Analyze_Associations, to handle actual packages that depend on
1233 previous instances. If a package IAP that is an instantiation is
1234 used as an actual in a subsequent instantiation SI in the same
1235 scope, and IAP has a body, IAP must be frozen before SI. If
1236 the generic parent of IAP is itself declared in a previous
1237 instantiation in the same scope, that instantiation must also
1238 be frozen before SI.

1254 initialization code.
1256 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1258 * a-wtdeio.adb (Put, all versions): Use Long_Long_Integer
1259 (Integer_Value (Item)) when the size of the fixed decimal type
1260 is larger than Integer.

1579 Make_Build_In_Place_Call_In_Anonymous_Context): Do not use the
1580 secondary stack for all functions that return limited tagged
1581 types -- just do it for dispatching calls. Misc cleanup.
1582 * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
1583 remove qualifications and type conversions. Fix various bugs
1584 where only a single level of qualification or conversion was
1585 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
1587 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
1590 2017-09-07 Ed Schonberg <schonberg@adacore.com>
1592 * sem_ch6.adb (setr_Actual_Subtypes): Within a predicate function
1593 do not create actual subtypes that may generate further predicate
1595 * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
1596 of body is a predicate function as well.
1597 (Resolve_Aspect_Expressions, Resolve_Name): For a component
1598 association, only the expression needs resolution, not the name.
1599 (Resolve_Aspect_Expressions, case Predicates): Construct and
1600 analyze the predicate function declaration in the scope of the
1601 type, before making the type and its discriminants visible.
1603 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
1605 * gcc-interface/decl.c (warn_on_field_placement): Issue the warning
1606 only if the record type itself comes from source.

1632 2017-09-06 Yannick Moy <moy@adacore.com>
1634 * sem_ch12.adb (Analyze_Instance_And_Renamings): Refactor to set
1635 global variable Ignore_SPARK_Mode_Pragmas_In_Instance only once.
1637 2017-09-06 Bob Duff <duff@adacore.com>
1639 * sem_ch8.adb: Change Assert to be consistent with
1642 2017-09-06 Bob Duff <duff@adacore.com>
1644 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
1645 requested. Previously, the -do switch meant "run Elab_New and
1646 Elab_Old and use the order chosen by Elab_Old, possibly with
1647 debugging printouts comparing the two orders." Now it means
1648 "do not run Elab_New." This is of use if there are bugs that
1649 cause Elab_New to crash.
1650 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
1652 * ali.ads (Elab_Position): Change type to Nat, to avoid various

1657 * sem_prag.adb (Check_Mode_Restriction_In_Enclosing_Context): Fix
1658 reference to SPARK RM.

1666 * freeze.adb (Freeze_Record_Type)
1667 <Sized_Component_Total_Round_RM_Size>: New local variable to
1668 accumulate the rounded RM_Size of components. Update it for
1669 every component whose RM_Size is statically known. Add missing
1670 guard to check that bit packing is really required before issuing
1671 the error about packing. Swap condition for clarity's sake.
1672 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.

1691 project manager sources.
1693 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1695 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
1696 entity of a mutable type and the right-hand side is a conditional
1697 expression, resolve the alternatives of the conditional using
1698 the base type of the target entity, because the alternatives
1699 may have distinct subtypes. This is particularly relevant if
1700 the alternatives are aggregates.
1702 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1704 * checks.adb (Apply_Predicate_Check): If the expression is an
1705 aggregate that is the RHS of an assignment, apply the check to
1706 the LHS after the assignment, rather than to the aggregate. This
1707 is more efficient than creating a temporary for the aggregate,
1708 and prevents back-end crashes when the aggregate includes a
1709 dynamic "others' association.
1711 2017-09-06 Yannick Moy <moy@adacore.com>
1713 * sem_ch12.adb (Analyze_Instance_And_Renamings):

1725 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.

1727 body. do not freeze the formals of the generic unit.
1729 2017-09-06 Gary Dismukes <dismukes@adacore.com>
1731 * errout.adb (Error_Msg): Separate the
1732 treatment for warning vs. style messages in inlinings and
1733 instantiations. Prevents blowups on calls to Warn_Insertion for
1734 style messages, which should not be called in that case because
1735 Warning_Msg_Char is not set.
1737 2017-09-06 Justin Squirek <squirek@adacore.com>
1739 * sem_prag.adb (Check_VFA_Conflicts): Created
1740 to group all Volatile_Full_Access checks relating to other
1741 representation pragmas (Mark_Component_Or_Object): Created
1742 to centeralize the flagging of attributes for the record type
1743 component case, a pragma applied individually to a component, and
1745 (Process_Atomic_Independent_Shared_Volatile):
1746 Add propagation of certain pragmas to record components and move
1747 evaluation of VFA checks

1760 2017-09-06 Bob Duff <duff@adacore.com>
1762 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
1763 that is a proper body corresponding to a stub, we defer the
1764 adjustment of the sloc until after the correct adjustment has
1765 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
1766 the adjustment, because it will be outside the range in (the old,
1767 incorrect) S_Adjustment.
1768 * inline.adb: Use named notation for readability and uniformity.
1769 * sinput-l.adb: Minor improvements to debugging output printed

1789 Set_Linker_Section_Pragma to be consistant with the "getter"
1790 Linker_Section_Pragma.
1791 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
1792 checking for container loops so that the index cursor is not
1793 directly changable by the user with the use of E_Loop_Parameter.
1794 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.

1839 Generate a freeze node for the actual of a formal package, if
1840 the actual is declared in the same unit and has a corresponding
1841 body, to prevent the current instance from being frozen before

1868 (Strip): New routine.
1870 2017-09-06 Bob Duff <duff@adacore.com>
1872 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
1873 we include the proper header. Otherwise, we just declare the necessary
1874 things from the capabilities library. This is so we can build on
1875 machines without that library, while still enabling that library.
1876 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
1877 simply return 0 if the library is not present, or not included

1893 has no parameter specification and no entry index, use the entry name
1894 as the end of the generated SCO statement.
1896 2017-09-06 Steve Baird <baird@adacore.com>
1898 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
1899 uses of 'Image and related attributes as having side effects in
1900 order to avoid replicating such uses.
1901 * pprint.ads (Expression_Image) Add new generic formal flag
1902 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
1903 (eventually) override the default.
1904 * pprint.adb (Expression_Image) If the new flag is set, then
1905 suppress the ".all" suffix when displaying a dereference whose
1906 prefix is a use of a value-capturing compiler temp of the sort
1907 generated by Expr_Util.Remove_Side_Effects .

1927 * sem_ch3.adb (Derived_Type_Declaration): Use
1928 Incomplete_Or_Partial_View rather than local Find_Partial_View.

1965 2017-09-06 Yannick Moy <moy@adacore.com>
1967 * freeze.adb (Check_Inherited_Conditions): Rewriting
1968 of inherited preconditions and postconditions should only occur
1969 in GNATprove mode, that is, when GNATprove_Mode is True, not to
1970 be confused with SPARK_Mode being On.

1987 (Entity_Table_Size): New constant.
1988 (Entity_Hash): New function.
1989 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
1990 (Is_Subprogram_Ref): Rename into...
1991 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
1992 the table instead of bailing out on them. Scan the value of constants
1993 if it is not known at compile time.
1994 (Contains_Subprograms_Refs): Rename into...
1995 (Scan_Subprogram_Refs): ...this.
1996 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
1997 Is_Public flag on subprograms if they are not actually referenced.
1998 (Hide_Public_Entities): Beef up comment on the algorithm.
1999 Reset the table of subprograms on entry.

2086 * sem_type.adb (Interface_Present_In_Ancestor): Within an
2087 expression function, or within a spec expression (default value,
2088 etc) a reference to an incomplete type is legal: legality of
2089 the operation will be checked when some related entity (type,
2090 object or subprogram) is frozen.
2092 2017-09-06 Gary Dismukes <dismukes@adacore.com>

2106 we can use modern Ada in this package.
2107 * s-resfil.ads, s-resfil.adb, a-clrefi.ads, a-clrefi.adb:
2108 Move Ada.Command_Line.Response_File to System.Response_File,
2109 and make Ada.Command_Line.Response_File into a rename of
2110 System.Response_File. This is to avoid having gnatbind depend
2111 Ada.Command_Line, which would damage the bootstrap process now
2112 that Ada.Command_Line contains modern Ada (the raise expression).
2113 * gnatbind.adb: Avoid dependence on
2114 Ada.Command_Line. Depend on System.Response_File instead
2115 of Ada.Command_Line.Response_File. Change one call to
2116 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
2117 to Ada.Command_Line.Argument_Count to use Arg_Count.
2118 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
2120 2017-09-06 Bob Duff <duff@adacore.com>
2122 * frontend.adb (Frontend): Skip -gnatec=gnat.adc

2127 * exp_ch5.adb (Get_Default_Iterator): Replace
2128 "Assert(False)" with "return Iter", because if an iterable

2184 procedure is No_Return.
2185 * sem_ch8.adb (Analyze_Subprogram_Renaming): Implement legality
2186 rule in 6.5.1 (7/2): if a renaming is a completion of a subprogram
2187 with No_Return, the renamed entity must be No_Return as well.
2189 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
2191 * exp_ch5.adb, freeze.adb, exp_ch4.adb, exp_ch6.adb, lib-xref.adb:

2208 * freeze.adb (Freeze_Entity): Do not generate a freeze
2209 node for a generic unit, even if it includes delayed aspect

2252 * exp_ch5.adb (Make_Field_Assign): If the type
2253 of the right-hand side has stored constraint, use its values
2254 (except for those that are renamings of parent discriminants)
2255 to produce additional assignments for the discriminants of the
2256 left-hand side, which are invisible in the righ-hand side and
2257 not retrievable as selected components.
2259 2017-09-06 Ed Schonberg <schonberg@adacore.com>
2261 * sem_util.adb (Needs_One_Formal): The first formal of such a
2262 function must be a controlling formal, so that Obj.F (X, Y)
2263 can have the interpretation F(Obj)(X, Y).
2264 * sem_util.ads: Clarify documentation.
2266 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>

2281 * sem_ch12.adb (Analyze_Subprogram_Instantiation): Propagate
2282 No_Return flag to instance if pragma applies to generic unit. This
2283 must be done explicitly because the pragma does not appear
2284 directly in the generic declaration (unlike the corresponding
2285 aspect specification).

2296 * exp_ch4.adb (Handle_Changed_Representation): For an untagged
2297 derived type with a mixture of renamed and constrained parent
2298 discriminants, the constraint for the target must obtain the
2299 discriminant values from both the operand and from the stored
2300 constraint for it, given that the constrained discriminants are
2301 not visible in the object.
2302 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
2303 side may be derived from that of the left-hand side (as in the
2304 case of an assignment with a change of representation) so the
2305 discriminant to be used in the retrieval of the value of the
2306 component must be the entity in the type of the right-hand side.
2308 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>

2334 * sem_ch4.adb (Analyze_Set_Membership): If an alternative
2335 in a set membership is an overloaded enumeration literal, and
2336 the type of the alternative is resolved from a previous one,
2337 replace the entity of the alternative as well as the type,
2338 to prevent inconsistencies between the entity and the type.

2882 accessibility entity created for an access parameter, handle
2883 properly a reference to a formal of an enclosing subprogram. if
2884 the reference appears in an inherited class-wide condition, it

2926 procedure body for a local (sub)type declaration within a

2971 Refine predicate for the case where the primitive operation
2972 is a renaming of equality. An overriding operation that is
2973 a user-defined renaming of predefined equality inherits its
2974 slot from the overridden operation. Otherwise it is treated
2975 as a predefined op and occupies the same predefined slot as
2976 equality. A call to it is transformed into a call to its alias,
2977 which is the predefined equality. A dispatching call thus uses
2978 the proper slot if operation is further inherited and called
2979 with class-wide arguments.

3061 parameter Array_Comp to indicate the case of an array object
3062 with null-excluding components.
3063 * checks.adb (Null_Exclusion_Static_Checks):
3064 Call Compile_Time_Constraint_Error instead of
3065 Apply_Compile_Time_Constraint_Error in the component case. Also
3066 call that when Array_Comp is True, with an appropriate warning for
3067 the array component case. Only create an explicit initialization
3068 by null in the case of an object of a null-excluding access type
3069 (and no longer do that in the component case).
3070 * sem_ch3.adb (Check_Component): Add a Boolean parameter
3071 Array_Comp defaulted to False. Pass Empty for the Comp
3072 actual when calling Null_Exclusion_Static_Checks in the case
3073 where Comp_Decl matches Object_Decl, because we don't have a
3074 component in that case. In the case of an object or component
3075 of an array type, pass True for Array_Comp on the recursive call
3078 2017-05-02 Bob Duff <duff@adacore.com>
3080 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
3081 compute the linux priority from the Ada priority. Call this everywhere
3082 required. In particular, the previous version was not doing this
3083 computation when setting the ceiling priority in various places. It
3084 was just converting to C.int, which results in a ceiling that is off
3087 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3089 * sem_ch3.adb: Comment predicate inheritance.
3091 2017-05-02 Tristan Gingold <gingold@adacore.com>
3093 * s-trasym.ads: Add comment.
3095 2017-05-02 Bob Duff <duff@adacore.com>
3097 * sem_elab.adb, sem_elab.ads: Minor comment fixes.
3098 * sem_ch4.adb: Minor reformatting.
3099 * s-taprop-linux.adb, s-taspri-posix.ads: Code refactoring.
3100 * s-taspri-posix-noaltstack.ads: Minor refactoring.
3101 * sinput.ads: Minor typo fix.
3103 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3105 * exp_ch9.adb (Discriminated_Size): Moved to sem_util.
3106 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
3107 here from exp_ch9, to recognize objects whose creation requires
3108 dynamic allocation, so that the proper warning can be emitted
3109 when restriction No_Implicit_Heap_Allocation is in effect.
3110 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
3111 to emit proper warning when an object that requires dynamic
3112 allocation is declared.
3114 2017-05-02 Tristan Gingold <gingold@adacore.com>
3116 * s-trasym.ads, s-trasym.adb (Enable_Cache): New.
3118 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3120 * sem_ch4.adb (Find_Equality_Types, Try_One_Interp): The same relaxed
3121 visibility rules for equality operators that apply within an
3122 instantiation apply within an inlined body.
3123 * sem_type.adb (Add_One_Interp): ditto.
3125 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
3127 * sem_prag.adb (Analyze_Pragma): Forbid pragma Contract_Cases on null
3130 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
3133 (Name_Assume, Name_Attribute_Definition, Name_Loop_Optimize,
3134 Name_No_Tagged_Streams): Move to regular pragmas. Add
3135 placeholders for Default_Scalar_Storage_Order, Dispatching_Domain,
3136 and Secondary_Stack_Size.
3137 (Pragma_Id): Move Pragma_Assume,
3138 Pragma_Attribute_Definition, Pragma_Loop_Optimize and
3139 Pragma_No_Tagged_Streams to second part.
3141 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
3143 * exp_attr.adb: Minor reformatting.
3145 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3147 * sem_ch4.adb (Analyze_Selected_Component): Improve error
3148 detection for illegal references to private components or
3149 operations of a protected type in the body of the type.
3151 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
3153 * opt.ads: Add missing GNAT markers in comments.
3154 * opt.adb (Set_Opt_Config_Switches): Do not override earlier
3155 settings of Optimize_Alignment at the end.
3157 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
3159 * checks.adb (Apply_Constraint_Check): Do not apply
3160 a discriminant check when the associated type is a constrained
3161 subtype created for an unconstrained nominal type.
3162 * exp_attr.adb: Minor reformatting.
3164 2017-05-02 Bob Duff <duff@adacore.com>
3166 * sem_ch3.adb (OK_For_Limited_Init_In_05): Handle correctly
3167 the N_Raise_Expression case.
3168 * sem_ch6.adb (Check_Limited_Return): Minor: clarify comment,
3171 2017-05-02 Yannick Moy <moy@adacore.com>
3173 * exp_ch4.adb (Expand_N_Op_Ne): Do not bump parenthese level and
3174 optimize length comparison in GNATprove mode.
3175 * exp_spark.adb (Expand_SPARK_Op_Ne): New function to rewrite
3176 operator /= into negation of operator = when needed.
3177 (Expand_SPARK): Call new
3178 function to expand operator /=.
3180 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3182 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
3183 Simplify the expression for a fixed-fixed division to remove
3184 divisions by constants whenever possible, as an optimization
3185 for restricted targets.
3187 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
3189 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
3191 2017-05-02 Bob Duff <duff@adacore.com>
3193 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
3194 to find primitive ops, instead of using an Identifier that will
3195 later be looked up. This is necessary because these ops are not
3196 necessarily visible at all places where we need to call them.
3197 * exp_util.ads: Minor comment fix.
3199 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3201 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
3202 references are fully conformant if they are both expansions
3203 of the discriminant of a protected type, within one of the
3204 protected operations. One occurrence may be expanded into a
3205 constant declaration while the other is an input parameter to
3206 the corresponding generated subprogram.
3208 2017-05-02 Justin Squirek <squirek@adacore.com>
3210 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
3211 recursivly searching composite-types for null-excluding access
3212 types and verifying them.
3213 (Analyze_Object_Declaration): Add a
3214 call to Check_Null_Excluding_Components for static verification
3215 of non-initialized objects.
3216 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
3217 a parameter for a composite-type's component and an extra case
3218 for printing component information.
3220 2017-05-02 Yannick Moy <moy@adacore.com>
3222 * sem_ch10.adb (Analyze_Subunit): Take
3223 configuration pragma into account when restoring appropriate
3224 pragma for analysis of subunit.
3226 2017-05-02 Justin Squirek <squirek@adacore.com>
3228 * s-tasren.adb, s-tasini.adb, s-taprop-linux.adb,
3229 s-mudido-affinity.adb,, a-exetim-posix.adb, a-direio.adb,
3230 g-socket.adb, s-taenca.adb, s-fileio.adb: Remove unused use-type
3231 clauses from the runtime.
3233 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
3235 * freeze.adb (Check_Component_Storage_Order): Do not treat bit-packed
3236 array components specially.
3238 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3240 * sem_ch8.adb (Premature_Usage): If the premature usage of
3241 an entity is as the expression in its own object decaration,
3242 rewrite the reference as Any_Id to prevent cascaded errors or
3243 compiler loops when such an entity is used in an address clause.
3245 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
3247 * gcc-interface/decl.c (components_to_record): Add missing guard.
3249 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
3251 * gcc-interface/decl.c (components_to_record): Add more comments.
3252 Put back pending fields onto the regular list if the misalignment
3253 happens to cancel itself.
3255 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3257 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
3258 controlling actual in a prefixed call, preserve the original node
3259 information if the prefix itself has been rewritten, for ASIS use.
3261 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3263 * exp_ch6.adb (Insert_Post_Call_Actions):
3264 Code clean up. Insert the post-call actions after an enclosing
3265 procedure call when N denotes a function call and appears as an
3266 actual parameter in the procedure call.
3268 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3270 * freeze.adb (Check_Component_Storage_Order): If there is a clause
3271 for the component, also reject the attribute if the component
3272 doesn't end on a byte boundary and its scalar storage order is
3273 different from that of the enclosing record type.
3275 2017-04-28 Javier Miranda <miranda@adacore.com>
3277 * atree.ads (Info_Messages): Removed.
3278 (Warning_Info_Messages): New counter.
3279 (Report_Info_Messages): New counter.
3280 * err_vars.ads Update documentation.
3281 * errout.adb (Delete_Warning_And_Continuations): Update
3282 Info_Message occurrences.
3283 (Error_Msg_Internal): Update Info_Message occurrences.
3284 (Delete_Warning): Update Info_Message occurrences.
3285 (Write_Error_Summary): Update Info_Message occurrences.
3286 (Output_Messages): Update Info_Message occurrences.
3287 (To_Be_Removed): Update Info_Message occurrences.
3288 (Reset_Warnings): Update Info_Message occurrences.
3289 * errutil.adb (Error_Msg): Update Info_Message occurrences.
3290 (Finalize): Update Info_Message occurrences.
3291 (Initialize): Update Info_Message occurrences.
3292 * erroutc.adb (Delete_Msg): Update Info_Message occurrences.
3293 (Compilation_Errors): Update Info_Message_Occurences.
3295 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3297 * exp_ch3.adb (Build_Init_Statements): Likewise on Nam.
3298 * freeze.adb (Check_Component_Storage_Order): And on Comp_Byte_Aligned.
3299 * sem_aggr.adb (Resolve_Record_Aggregate): Initialize Box_Node.
3300 * sem_attr.adb (Loop_Entry): Initialize Encl_Loop.
3301 * sem_ch12.adb (Build_Operator_Wrapper): Add pragma Warnings on Expr.

3304 * sem_eval.adb (Why_Not_Static): Initialize Typ.
3305 * sem_prag.adb (Analyze_Pragma): Add pragma Warnings on Str.
3307 2017-04-28 Bob Duff <duff@adacore.com>
3309 * sem_util.ads, sem_util.adb (Might_Raise): New function
3310 that replaces Is_Exception_Safe, but has the opposite
3311 sense. Is_Exception_Safe was missing various cases -- calls inside
3312 a pragma Debug, calls inside an 'if' or assignment statement,
3313 etc. Might_Raise now walks the entire subtree looking for things
3315 * exp_ch9.adb (Is_Exception_Safe): Remove.
3316 (Build_Protected_Subprogram_Body): Replace call to
3317 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
3318 constants where possible).
3319 * exp_ch7.adb: Rename Is_Protected_Body -->
3320 Is_Protected_Subp_Body. A protected_body is something different
3323 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3325 * inline.adb (Expand_Inlined_Call): Initialize Targ1 variable.
3326 * par-ch3.adb (P_Component_Items): Initialize Decl_Node variable.

3333 * sem_ch4.adb (List_Operand_Interps): Add pragma Warnings on variable.
3334 * sem_ch5.adb (Analyze_Assignment): Initialize Save_Full_Analysis.
3335 (Analyze_Exit_Statement): Initialize Scope_Id variable.
3336 (Analyze_Iterator_Specification): Initialize Bas variable.
3337 * sem_ch9.adb (Allows_Lock_Free_Implementation): Initialize
3338 Error_Count (Satisfies_Lock_Free_Requirements): Likewise.
3339 (Analyze_Accept_Statement): Initialize Task_Nam.
3341 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3343 * checks.adb (Install_Primitive_Elaboration_Check):
3344 Do not generate an elaboration check if all checks have been
3347 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3349 * sem_ch13.adb (Analyze_Aspect_Specifications, case
3350 Interrupt_Handler and Attach_Handler): Generate reference
3351 to protected operation to prevent spurious warnings about
3352 unreferenced entities. Previous scheme failed with style checks
3355 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3357 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
3358 that follows an expression function must not be relocated to
3359 the generated body, because it applies to the code that follows.
3361 2017-04-28 Gary Dismukes <dismukes@adacore.com>
3363 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
3364 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
3365 code that might violate the more stringent checking for 'Access
3366 introduced in Ada 2005.
3368 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3370 * a-cforse.adb: minor style fix in comment.
3372 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3374 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
3375 initialize Block_Decls variable.
3376 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
3377 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.
3378 * exp_disp.adb (Expand_Interface_Actuals): Initialize
3379 Formal_DDT and Actual_DDT variables.
3380 (Expand_Interface_Thunk): Initialize Iface_Formal.
3381 (Make_DT): Initialize Size_Comp.
3382 (Make_Select_Specific_Data_Table): Initialize Decls.
3383 * exp_dist.adb (Add_RACW_Primitive_Declarations_And_Bodies):
3384 Also initialize more RPC_Receiver_* variables.
3385 (Build_To_Any_Function): Initialize Cstr_Formal.
3386 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
3388 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3390 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
3391 node between access types, freeze the designated type as well,
3392 so that dispatch table pointers are created in the proper scope,
3393 and not in the constructed body of the expression function.
3395 2017-04-28 Bob Duff <duff@adacore.com>
3397 * alloc.ads (Nodes_Initial): Go back to previous value. The large
3398 value makes large compilations faster, but small compilations slower.
3400 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3402 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
3404 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3406 * erroutc.adb (Compilation_Errors): Do not consider info messages
3407 as suitable warnings when warnings must be treated as errors.
3408 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
3409 internally-generated packages when outputting completion
3411 * errout.adb (Output_Messages): Do not consider info messages as
3412 suitable warnings when warnings must be treated as errors.
3413 * errutil.adb (Finalize): Do not consider info messages as
3414 suitable warnings when warnings must be treated as errors.
3416 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3418 * warnsw.ads: Minor fix for incorrect wording in comment.
3420 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3422 * sem_res.adb (In_Instance_Code): New predicate in
3423 Valid_Conversion, to determine whether a type conversion appears
3424 as (or within) an actual for a formal object. Type conversions
3425 in instances are not rechecked in Valid_Conversion because
3426 visibility changes between generic location andi instance may
3427 lead to spurious errors, but conversions within an actual must be
3428 fully checked, and they are not fully resolved when pre-analyzing
3431 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3433 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
3434 New_Copy_Tree instead of Relocate_Node as any subsequent copies
3435 of the relocated node will have mangled Parent pointers.
3436 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
3437 tables used in conjunction with entity and itype replication.
3438 (Visit_Entity): Rewrite the restriction on which entities
3439 require duplication. The restriction now includes all types.
3441 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3443 * a-cofuse.ads, a-cfdlli.ads, a-cfhase.adb, a-cfhase.ads, a-cfinve.adb,

3453 2017-04-28 Gary Dismukes <dismukes@adacore.com>
3455 * exp_util.adb: Minor reformatting.
3457 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3459 * sem_ch4.adb: Fix copy/pasto.
3461 2017-04-27 Tristan Gingold <gingold@adacore.com>
3463 * gcc-interface/Make-lang.in: Define EH_MECHANISM while building
3464 raise-gcc.c. Fix include search path for raise-gcc.c
3466 2017-04-27 Eric Botcazou <ebotcazou@adacore.com>
3468 * fe.h (Warn_On_Questionable_Layout): Declare.
3469 * warnsw.ads (Warn_On_Record_Holes): Move down.
3470 (Warn_On_Questionable_Layout): New boolean variable.
3471 (Warning_Record): Add Warn_On_Questionable_Layout field.
3472 * warnsw.adb (All_Warnings): Set Warn_On_Questionable_Layout.
3473 (Restore_Warnings): Likewise.
3474 (Save_Warnings): Likewise.
3475 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
3476 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
3477 components_to_record.
3478 (gnu_field_to_gnat): New function.
3479 (warn_on_field_placement): Likewise.
3480 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
3481 parameters. Rename local variables and adjust recursive call.
3482 Rework final scan of the field list and implement warnings on the
3483 problematic placement of specific sorts of fields.
3485 2017-04-27 Bob Duff <duff@adacore.com>
3487 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,
3488 * fname.ads, freeze.adb, inline.adb, lib.adb, lib.ads, lib-list.adb,
3489 * lib-load.adb, lib-writ.adb, par.adb, restrict.adb, rtsfind.adb,

3491 * sem_ch4.adb, sem_ch6.adb, sem_ch8.adb, sem_ch9.adb, sem_elab.adb,
3492 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
3493 For efficiency, cache results of Is_Internal_File_Name and
3494 Is_Predefined_File_Name in the Units table. This avoids a lot
3495 of repeated text processing.
3497 2017-04-27 Emmanuel Briot <briot@adacore.com>
3499 * g-comlin.adb (Sort_Sections): remove useless test.
3501 2017-04-27 Claire Dross <dross@adacore.com>
3503 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
3504 allow the use of regular equality over elements in contracts.
3505 (Formal_Model): Ghost package containing model functions that are
3506 used in subprogram contracts.
3507 (Current_To_Last): Removed, model functions should be used instead.
3508 (First_To_Previous): Removed, model functions should be used instead.
3509 (Strict_Equal): Removed, model functions should be used instead.
3510 (No_Overlap): Removed, model functions should be used instead.
3511 (Equivalent_Keys): Functions over cursors are removed. They were
3512 awkward with explicit container parameters.
3513 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
3514 allow the use of regular equality over elements in contracts.
3515 (Formal_Model): Ghost package containing model functions that
3516 are used in subprogram contracts.
3517 (Current_To_Last): Removed, model functions should be used instead.
3518 (First_To_Previous): Removed, model functions should be used instead.
3519 (Strict_Equal): Removed, model functions should be used instead.
3520 (No_Overlap): Removed, model functions should be used instead.
3522 2017-04-27 Yannick Moy <moy@adacore.com>
3524 * gnat1drv.adb: Code cleanup.
3526 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3528 * exp_util.adb (Replace_Entity): The prefix of a 'Result
3529 attribute reference in a post- condition is the subprogram to
3530 which the condition applies. If the condition is inherited
3531 by a type extension, the prefix becomes a reference to the
3532 inherited operation, but there is no need to create a wrapper
3533 for this operation, because 'Result is expanded independently
3534 when elaborating the postconditions.
3536 2017-04-27 Bob Duff <duff@adacore.com>
3538 * sinput.adb: Minor code cleanup.
3539 * namet.adb (Append): Create faster versions of
3540 Append(String) and Append(Name_Id) by using slice assignment
3542 * sem_util.adb (In_Instance): Speed this up by removing
3543 unnecessary tests; Is_Generic_Instance is defined for all
3545 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
3546 Remove unused function.
3547 * alloc.ads (Nodes_Initial): Use a much larger value, because
3548 the compiler was spending a lot of time copying the nodes table
3549 when it grows. This number was chosen in 1996, so is rather out
3550 of date with current memory sizes. Anyway, it's virtual memory.
3551 Get rid of Orig_Nodes_...; use Node_... instead.

4072 perform check if the current scope does not come from source,
4073 as is the case for a rewritten task body, because check has
4074 been performed already, and may not be doable because of changed

4087 replace the type of the call by the full view, to prevent spurious
4089 * exp_disp.adb (Check_Premature_Freezing): Disable check on an
4090 abstract subprogram so that compiler does not reject a parameter
4091 of a primitive operation of a tagged type being frozen, when
4092 the untagged type of that parameter cannot be frozen.

4130 modifications in functional containers.
4131 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4132 to improve readablity. Subprograms are separated between basic
4133 operations, constructors and properties. Universally quantified
4134 formulas in contracts are factorized in independant functions
4135 with a name and a comment. Names of parameters are improved.
4137 2017-04-27 Gary Dismukes <dismukes@adacore.com>
4139 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.

4143 * sem_res.adb (Resolve_Type_Conversion): Do not
4144 install a predicate check here since this is already done during
4145 the expansion phase. Verify whether the operand satisfies the
4146 static predicate (if any) of the target type.
4147 * sem_ch3.adb (Analyze_Object_Declaration): Do
4148 not install a predicate check if the object is initialized by
4149 means of a type conversion because the conversion is subjected

4225 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
4226 the loop which detects potential enclosing transient scopes. The
4227 loop now terminates much earlier as transient scopes are bounded
4228 by packages and subprograms.
4230 2017-04-27 Claire Dross <dross@adacore.com>
4232 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
4233 allow the use of regular equality over elements in contracts.

4240 (First_To_Previous): Removed, model functions should
4242 (Strict_Equal): Removed, model functions
4243 should be used instead.
4244 (Append): Default parameter value
4245 replaced by new wrapper to allow more precise contracts.

4287 * debug.adb Change the documentation of switch -gnatd.s.
4288 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
4289 to manage the secondary stack when an enclosing scope already
4290 performs this functionality (aka relaxed management). Switch
4291 -gnatd.s may be used to force strict management in which case
4292 the block will manage the secondary stack unconditionally. Add
4293 a guard to stop the traversal when encountering a package or a
4296 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4298 * sem_res.adb (Resolve_Call): Refine further the handling of
4299 limited views of return types in function calls. If the function
4300 that returns a limited view appears in the current unit,
4301 we do not replace its type by the non-limited view because
4302 this transformation is performed int the back-end. However,
4303 the type of the call itself must be the non-limited view, to
4304 prevent spurious resolution errors.
4306 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4308 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
4309 Removed, proposed implementation using generics for class-wide
4310 preconditions proved impractical.
4311 (Class_Wide_Clone): New attribute of subprogram. Designates
4312 subprogram created for primitive operations with class-wide
4313 pre/postconditions that contain calls to other primitives. The
4314 clone holds the body of the original primitive, but the
4315 pre/postonditions do not apply to it. The original body is
4316 rewritten as a wrapper for a call to the clone.
4317 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
4318 the flag is set, no code for the corresponding pre/postconditions
4319 is inserted into its body.
4321 2017-04-27 Bob Duff <duff@adacore.com>
4323 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore

4367 private child of Ada.Containers used to implement all functional
4369 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
4370 child of Ada.Containers. It provides functional indefinite unbounded
4371 maps which can be used as high level models for specification
4373 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
4374 child of Ada.Containers. It provides functional indefinite unbounded
4375 sets which can be used as high level models for specification
4377 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
4378 child of Ada.Containers. It provides functional indefinite unbounded
4379 vectors which can be used as high level models for specification

4388 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4390 * sem_ch12.adb (Analyze_Associations): minor reformatting.
4391 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
4392 point type actual that has user-defined arithmetic primitives,
4393 when there is a previous actual for a formal package that defines
4394 a fixed-point type with the parent user-defined operator.
4396 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4398 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
4399 * sem_attr.adb (Resolve_Attribute): Generate a range check when
4400 the component type allows range checks.
4402 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4404 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
4405 corresponding declaration, because formal derived types are
4406 rewritten as private extensions.
4408 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4410 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
4411 dimensions of operands if node has been analyzed already, because
4412 previous analysis and dimension checking will have removed the
4413 dimension information from the operands.
4415 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4417 * debug.adb: Document the use of switch -gnatd.s.
4418 * einfo.ads Update the documentation on attribute
4419 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
4420 the uses of these attributes from certain entities.

4422 which determines whether the block should continue to manage
4423 the secondary stack.

4472 generating C code on complex case expressions.
4474 2017-04-25 Arnaud Charlet <charlet@adacore.com>
4476 * sem_prag.adb (Analyze_Pragma): Generate a warning instead
4477 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
4478 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
4479 Ada_2012 instead of Ada_2005 to be compatible with the above
4481 * bindgen.adb: Silence new warning on pragma Ada_95.
4483 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

4500 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
4501 * sinput-p.adb: Use regular fat pointers, with bounds checking,
4502 for source buffers. Fix misc obscure bugs.
4503 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
4504 checking, for source buffers. Modify representation clause for
4505 Source_File_Record as appropriate. Move Source_File_Index_Table
4506 from spec to body, because it is not used outside the body.
4507 Move Set_Source_File_Index_Table into the private part, because
4508 it is used only in the body and in children. Use trickery to
4509 modify the dope in the generic instantiation case. It's ugly,
4510 but not as ugly as the previous method. Fix documentation.
4511 Remove obsolete code.

4527 expander is not active or when index/range checks are suppressed
4529 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
4530 Remove variants that include a Supress parameter. These routines
4531 are never used, and were introduced before the current scope-based
4532 check suppression method.

5076 2017-04-25 Justin Squirek <squirek@adacore.com>
5078 * exp_ch3.adb (Freeze_Type): Add condition to always treat
5079 interface types as a partial view of a private type for the
5080 generation of invariant procedure bodies.
5081 * exp_util.adb, exp_util.ads (Add_Inherited_Invariants):
5082 Add a condition to get the Corresponding_Record_Type for
5083 concurrent types, add condition to return in the absence of a
5084 class in the pragma, remove call to Replace_Type_References,
5085 and add call to Replace_References.
5086 (Add_Interface_Invariatns),
5087 (Add_Parent_Invariants): Modify call to Add_Inherited_Invariants
5088 to including the working type T.
5089 (Add_Own_Invariants): Remove
5090 legacy condition for separate units, remove dispatching for ASIS
5091 and save a copy of the expression in the pragma expression.
5092 (Build_Invariant_Procedure_Body): Default initalize vars,
5093 remove return condition on interfaces, always use the
5094 private type for interfaces, and move the processing of types
5095 until after the processing of invariants for the full view.
5096 (Build_Invariant_Procedure_Declaration): Remove condition
5097 to return if an interface type is encountered and add
5098 condition to convert the formal parameter to its class-wide
5099 counterpart if Work_Typ is abstract.
5100 (Replace_Type): Add call to Remove_Controlling_Arguments.
5101 (Replace_Type_Ref): Remove class-wide dispatching for the current
5102 instance of the type.
5103 (Replace_Type_References): Remove parameter "Derived"
5104 (Remove_Controlling_Arguments): Created in order to removing
5105 the controlliong argument from calls to primitives in the case
5106 of the formal parameter being an class-wide abstract type.
5107 * sem_ch3.adb (Build_Assertion_Bodies_For_Type): Almost identical
5108 to the change made to Freeze_Type in exp_ch3. Add a condition
5109 to treat interface types as a partial view.
5110 * sem_prag.adb (Analyze_Pragma): Modify parameters in the call
5111 to Build_Invariant_Procedure_Declaration to properly generate a
5112 "partial" invariant procedure when Typ is an interface.
5114 2017-04-25 Bob Duff <duff@adacore.com>
5116 * a-numeri.ads: Go back to using brackets encoding for the Greek
5119 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5121 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
5122 (10-15): if derived type T with progenitors is abstract,
5123 and primitive P of this type inherits non-trivial classwide
5124 preconditions from both a parent operation and from an interface
5125 operation, then the inherited operation is abstract if the parent
5126 operation is not null.
5127 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
5128 with Covered_Interface_Op to yield the actual interface operation
5129 that is implemented by a given inherited operation.
5131 2017-04-25 Javier Miranda <miranda@adacore.com>
5133 * exp_ch4.adb (Expand_N_Op_Expon): Relocate left
5134 and right operands after performing the validity checks. Required
5135 because validity checks may remove side effects from the operands.
5137 2017-04-25 Javier Miranda <miranda@adacore.com>
5139 * exp_attr.adb (Attribute_Unrestricted_Access):
5140 Do not disable implicit type conversion. Required to generate
5141 code that displaces the pointer to reference the secondary
5144 2017-04-25 Pascal Obry <obry@adacore.com>
5146 * prj-attr.adb, snames.ads-tmpl: Add package Install's
5147 Required_Artifacts attribute.
5149 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5151 * sem_util.adb (Same_Value): String literals are compile-time
5152 values, and comparing them must use Expr_Value_S.
5154 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5156 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
5157 dereference is introduced for the object, and the object is
5158 overloaded, do not check whether it is aliased, because it may
5159 include an implicit dereference.
5160 * sem_type.adb (Disambiguate): If two interpretations are access
5161 attribute types with the same designated type keep either of
5162 them and do not report an ambiguity. A true ambiguity will be
5165 2017-04-25 Bob Duff <duff@adacore.com>
5167 * a-numeri.ads: Change the encoding of Greek letter Pi from
5168 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
5169 to indicate the encoding. We considered using a byte order mark
5170 (BOM), but that causes various trouble (misc software eats the
5171 BOM, if you have a patch with a BOM, then it's not at the start
5172 of the patch, so it's not a BOM, the BOM affects with-ing files,
5174 * scng.adb, s-wchcnv.adb: Minor.
5176 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

5186 moved here from sem_ch3.
5187 * sem_ch8.adb (Analyze_Subprogram_Renaming): Implement legality
5188 check given in RM 6.1.1 (17) concerning renamings of overriding
5189 operations that inherits class-wide preconditions from ancestor
5192 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

5210 restrictions when the handler is internally generated and the
5213 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5215 * sem_ch3.adb (Has_Non_Trivial_Precondition): New predicate to
5216 enforce legality rule on classwide preconditions inherited from
5217 both an ancestor and a progenitor (RM 6.1.1 (10-13).
5218 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
5219 subprogram need not be dispatching if it appears in a precondition
5220 for an abstract or null subprogram.
5222 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5224 * sem_ch10.adb: Minor typo fix.
5226 2017-04-25 Arnaud Charlet <charlet@adacore.com>
5228 * gcc-interface/Makefile.in: Cleanup VxWorks targets.
5230 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5232 * fname.adb (Is_Internal_File_Name): Arrange for the slices to
5233 have a length which is a power of 2.
5234 (Is_Predefined_File_Name): Likewise. Adjust comment.
5236 2017-04-25 Bob Duff <duff@adacore.com>
5238 * exp_aggr.adb (Component_Count): Protect the
5239 arithmetic from attempting to convert a value >= 2**31 to Int,
5240 which would otherwise raise Constraint_Error.
5242 2017-04-25 Bob Duff <duff@adacore.com>
5244 * opt.ads (Locking_Policy): Fix incorrect documentation. The
5245 first character of the policy name is not unique.
5247 2017-04-25 Bob Duff <duff@adacore.com>
5249 * s-fileio.adb (Name): Raise Use_Error if the file is a temp file.
5250 * s-ficobl.ads (Is_Temporary_File): Remove incorrect comment
5251 about this flag not being used. It was already used, and it is
5254 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5256 * einfo.adb Flag301 is now known as Ignore_SPARK_Mode_Pragmas.
5257 (Ignore_SPARK_Mode_Pragmas): New routine.
5258 (Set_Ignore_SPARK_Mode_Pragmas): New routine.
5259 (Write_Entity_Flags): Add an entry for Ignore_SPARK_Mode_Pragmas.

5268 Save and restore the value of global flag
5269 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value
5270 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance when either
5271 the corresponding spec or the body must ignore all SPARK_Mode
5272 pragmas found within.
5273 (Analyze_Subprogram_Declaration): Mark
5274 the spec when it needs to ignore all SPARK_Mode pragmas found
5275 within to allow the body to infer this property in case it is
5276 instantiated or inlined later.
5277 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
5278 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
5279 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
5280 when the corresponding spec also ignored all SPARK_Mode pragmas
5282 (Analyze_Package_Declaration): Mark the spec when
5283 it needs to ignore all SPARK_Mode pragmas found within to allow
5284 the body to infer this property in case it is instantiated or
5286 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
5287 Save and restore the value of flag
5288 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
5289 formal spec when it needs to ignore all SPARK_Mode
5290 pragmas found within to allow the body to infer this
5291 property in case it is instantiated or inlined later.
5292 (Analyze_Package_Instantiation): Save and restore the value
5293 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
5294 the instance spec when it needs to ignore all SPARK_Mode
5295 pragmas found within to allow the body to infer this
5296 property in case it is instantiated or inlined later.

5298 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
5299 instance spec and anonymous package when they need to ignore
5300 all SPARK_Mode pragmas found within to allow the body to infer
5301 this property in case it is instantiated or inlined later.
5302 (Instantiate_Package_Body): Save and restore the value of global
5303 flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set the value of

5313 Ignore_Pragma_SPARK_Mode.
5314 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
5315 all SPARK_Mode pragmas defined within yields mode "off".
5317 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5319 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.
5321 2017-04-25 Bob Duff <duff@adacore.com>
5323 * exp_atag.adb (Build_CW_Membership): Add "Suppress =>
5324 All_Checks" to avoid generating unnecessary checks.
5325 * exp_ch4.adb (Expand_N_In, Make_Tag_Check): Add "Suppress =>
5327 * sem.ads: Fix comment.
5328 * expander.ads: Fix comment.

5332 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5334 * s-taprop-linux.adb: Minor editorial fixes.
5336 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5338 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
5339 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
5340 variable and set it to True whenever the main hash table is
5341 populated. Short- circuit the Assoc function if it is false
5342 and add associated guards.
5344 2017-04-25 Olivier Hainque <hainque@adacore.com>
5346 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
5347 specs without elaboration code that have an elaboration counter
5348 nevertheless, e.g. when compiled with -fpreserve-control-flow.
5349 * sem_ch10.adb (Analyze_Compilation_Unit):
5350 Set_Elaboration_Entity_Required when requested to preserve
5351 control flow, to ensure the unit elaboration is materialized at
5352 bind time, resulting in the inclusion of the unit object file
5353 in the executable closure at link time.
5355 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
5357 * exp_dbug.adb: In Debug_Renaming_Declaration,
5358 when dealing with indexed component, accept to produce a renaming
5359 symbol when the index is an IN parameter or when it is a name
5360 defined in an outer scope.
5362 2017-04-25 Yannick Moy <moy@adacore.com>
5364 * errout.adb (Error_Msg): Adapt continuation
5365 message in instantiations and inlined bodies for info messages.
5367 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5369 * fname.adb (Has_Internal_Extension): Add pragma Inline.
5370 Use direct 4-character slice comparisons.
5372 pragma Inline. (Has_Suffix): Delete.
5373 (Is_Internal_File_Name):
5374 Test Is_Predefined_File_Name first.
5375 (Is_Predefined_File_Name):

5379 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5381 * checks.adb (Insert_Valid_Check): Code cleanup.
5382 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
5383 (Expand_Actuals): Generate proper copy-back for a validation
5384 variable when it acts as the argument of a type conversion.
5385 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
5386 predicate to operate on type qualifications.
5388 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5390 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
5393 2017-04-25 Bob Duff <duff@adacore.com>
5395 * sem_prag.adb (No_Return): Give an error if the pragma applies
5396 to a body. Specialize the error for the specless body case,
5397 as is done for (e.g.) pragma Convention.
5398 * debug.adb: Add switch -gnatd.J to disable the above legality
5399 checks. This is mainly for use in our test suite, to avoid
5400 rewriting a lot of illegal (but working) code. It might also
5401 be useful to customers. Under this switch, if a pragma No_Return
5402 applies to a body, and the procedure raises an exception (as it
5403 should), the pragma has no effect. If the procedure does return,
5404 execution is erroneous.
5406 2017-04-25 Bob Duff <duff@adacore.com>
5408 * exp_ch6.adb (Expand_Actuals): This is the
5409 root of the problem. It took N as an 'in out' parameter, and in
5410 some cases, rewrote N, but then set N to Original_Node(N). So
5411 the node returned in N had no Parent. The caller continued
5412 processing of this orphaned node. In some cases that caused a
5413 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
5414 and trips over the Empty Parent). The solution is to make N an
5415 'in' parameter. Instead of rewriting it, return the list of
5416 post-call actions, so the caller can do the rewriting later,
5417 after N has been fully processed.
5418 (Expand_Call_Helper): Move most of Expand_Call here. It has
5419 too many premature 'return' statements, and we want to do the
5420 rewriting on return.
5421 (Insert_Post_Call_Actions): New procedure to insert the post-call
5422 actions in the appropriate place. In the problematic case,
5423 that involves rewriting N as an Expression_With_Actions.
5424 (Expand_Call): Call the new procedures Expand_Call_Helper and
5425 Insert_Post_Call_Actions.
5427 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5429 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
5430 properly type derived from generic formal types, to handle
5431 properly modified version of ACATS 4.1B B611017.
5433 2017-04-25 Javier Miranda <miranda@adacore.com>
5435 * exp_unst.adb (Subp_Index): Adding missing
5436 support for renamings and functions that return a constrained
5437 array type (i.e. functions for which the frontend built a
5438 procedure with an extra out parameter).
5440 2017-04-25 Pascal Obry <obry@adacore.com>
5442 * s-string.adb: Minor code clean-up.
5444 2017-04-25 Bob Duff <duff@adacore.com>
5446 * s-os_lib.ads, s-os_lib.adb (Non_Blocking_Wait_Process): New
5448 * adaint.h, adaint.c (__gnat_portable_no_block_wait): C support
5449 function for Non_Blocking_Wait_Process.
5451 2017-04-25 Bob Duff <duff@adacore.com>
5453 * prep.adb (Preprocess): Remove incorrect
5454 Assert. Current character can be ASCII.CR.
5456 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5458 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
5459 convention Stdcall, which has a number of exceptions. Convention
5460 is legal on a component declaration whose type is an anonymous
5461 access to subprogram.
5463 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5465 * sem_ch4.adb: sem_ch4.adb Various reformattings.
5466 (Try_One_Prefix_Interpretation): Use the base type when dealing
5467 with a subtype created for purposes of constraining a private
5468 type with discriminants.
5470 2017-04-25 Javier Miranda <miranda@adacore.com>
5472 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.

5474 dispatching primitives (Restore_Warnings): Restore warning on
5475 late dispatching primitives (Save_Warnings): Save warning on late
5476 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
5477 to enable/disable this warning.
5478 (WA_Warnings): Set warning on late dispatching primitives.
5479 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
5480 that its parent type has a private extension.
5481 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
5483 * usage.adb: Document -gnatw.j and -gnatw.J.
5485 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5487 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
5490 2017-04-25 Bob Duff <duff@adacore.com>
5492 * binde.adb (Validate): Do not pass dynamic strings
5493 to pragma Assert, because older compilers do not support that.
5495 2017-04-25 Bob Duff <duff@adacore.com>
5497 * s-fileio.adb (Close): When a temp file is
5498 closed, delete it and clean up its Temp_File_Record immediately,
5499 rather than waiting until later.
5500 (Temp_File_Record): Add File
5501 component, so Close can know which Temp_File_Record corresponds
5502 to the file being closed.
5503 (Delete): Don't delete temp files,
5504 because they are deleted by Close.
5505 (Open): Set the File component
5506 of Temp_File_Record. This requires moving the creation of the
5507 Temp_File_Record to the end, after the AFCB has been created.
5509 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5511 * checks.adb (Insert_Valid_Check): Do not generate
5512 a validity check when inside a generic.

5525 * sem_prag.adb (Analyze_Pre_Post_Condition): The rules
5526 concerning inheritance of class-wide preconditions do not apply
5529 2017-04-25 Bob Duff <duff@adacore.com>
5531 * s-ficobl.ads: Minor comment fix.
5533 2017-04-25 Yannick Moy <moy@adacore.com>
5535 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
5536 conversions from float to integer in GNATprove mode.
5537 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
5538 to call Apply_Type_Conversion_Checks, so that range checks
5539 are properly positioned when needed on conversions, including
5540 when converting from float to integer. (Determine_Range): In
5541 GNATprove mode, take into account the possibility of conversion
5542 from float to integer.
5543 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
5544 check on conversions from fixed-point to integer, not anymore
5545 on conversions from floating-point to integer, when in GNATprove
5548 2017-04-25 Yannick Moy <moy@adacore.com>
5550 * checks.adb (Determine_Range_R): Special case type conversions
5551 from integer to float in order to get bounds in that case too.
5552 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
5553 mode, for computations involved in interval checking.

5567 * exp_attr.adb (Make_Range_Test): Add processing for validation
5568 variables to avoid extra reads and copies of the prefix.
5569 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation

5587 Pre'Class aspect is specified for the corresponding primitive
5588 subprogram of some ancestor of T.
5590 2017-04-25 Bob Duff <duff@adacore.com>
5592 * sem_ch8.adb (Use_One_Type): If a use_type_clause
5593 is redundant, set its Used_Operations to empty. This is only
5594 necessary for use clauses that appear in the parent of a generic
5595 child unit, because those use clauses get reanalyzed when we
5596 instantiate the generic, and we don't want the Used_Operations
5597 carried over from the original context (where it was probably

5610 * par.adb (Par): Null out Current_Source_File, to ensure that
5611 the above bugs won't rear their ugly heads again.
5613 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5615 * sem_ch8.adb (Find_Type): For an attribute reference
5616 'Class, if prefix type is synchronized and previous errors
5617 have suppressed the creation of the corresponding record type,
5618 create a spurious class-wide for the synchonized type itself,
5619 to catch other misuses of the attribute

5623 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
5624 is True, then don't generate the accessibility check for the
5625 tag of a tagged result.

5628 tag checks for the result of call to an instance of
5629 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
5630 descendant of" check and the accessibility check).
5632 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5634 * sem_ch13.adb: Code cleanups.
5635 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

5640 * exp_ch4.adb (Library_Level_Target): New function.
5641 (Expand_Concatenate): When optimization is enabled, also expand
5642 the operation out-of-line if the concatenation is present within
5643 the expression of the declaration of a library-level object and
5644 not only if it is the expression of the declaration.
5646 2017-04-25 Bob Duff <duff@adacore.com>
5648 * freeze.adb (Freeze_Object_Declaration): Do
5649 not Remove_Side_Effects if there is a pragma Linker_Section,
5650 because in that case we want static initialization in the
5651 appropriate section.
5653 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5655 * exp_dbug.adb: Minor rewording and reformatting.
5657 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5659 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
5660 handle the proposed changes to rules concerning potentially
5661 unevaluated expressions, to include selected components that
5662 do not depend on discriminants, and indexed components with

5665 predicate in quantified expression, and fix bugs in the handling
5666 of case expressions and membership test.

5684 renaming entity for debug information, mark the entity as needing debug
5685 info if it comes from sources.
5687 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5689 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the

5708 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
5709 internal calls that appear in preconditions of protected
5710 operations, in default values for same, and in contract guards
5711 for contract cases in SPARK.
5713 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5715 * a-numaux.ads: Fix description of a-numaux-darwin

5722 * a-numaux-x86.ads: Fix package description.
5723 * a-numaux-x86.adb (Is_Nan): Minor tweak.
5724 (Reduce): Adjust and complete description. Call Is_Nan instead of
5725 testing manually. Use an integer temporary to hold rounded value.
5726 * a-numaux-darwin.adb (Reduce): Likewise.
5727 (Is_Nan): New function.
5729 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5731 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
5732 on analysis of prefix whose type is a current instance of a
5733 synchronized type, but where the prefix itself is an entity that
5736 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5738 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
5739 the identity of callable entities therein, because they have been
5740 properly resolved, and prefixed calls may have been rewritten

5745 * exp_ch3.adb (Build_Init_Statements): Convert
5746 the expression of the pragma/aspect Secondary_Stack_Size to

5761 2017-04-25 Javier Miranda <miranda@adacore.com>
5763 * urealp.adb (UR_Write): Reverse previous patch
5764 adding documentation on why we generate multiplications instead
5765 of divisions (needed to avoid expressions whose computation with
5766 large numbers may cause division by 0).
5768 2017-04-25 Bob Duff <duff@adacore.com>
5770 * erroutc.adb (Set_Specific_Warning_Off,
5771 Set_Warnings_Mode_Off): Use the correct source file for
5772 Stop. Was using Current_Source_File, which is only valid during
5773 parsing. Current_Source_File will have a leftover value from
5774 whatever file happened to be parsed last, because of a with_clause
5777 2017-04-25 Bob Duff <duff@adacore.com>
5779 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
5780 to In_Predefined_Unit, but including GNAT units.
5781 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
5782 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
5783 because Should_Ignore_Pragma was not working reliably outside
5784 the parser, because Current_Source_File is not valid.
5785 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
5786 * par-prag.adb: Call Should_Ignore_Pragma_Par.

5850 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
5853 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5855 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
5856 of prefix whose type is a current instance of a synchronized
5857 type. If the prefix is an object this is an external call (or
5858 requeue) that can only access public operations of the object. The
5859 previous predicate was too restrictive, and did not allow public
5860 protected operations, only task entries.
5862 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5864 * sem_ch5.adb, fname.adb: Minor reformatting.
5866 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5868 * einfo.adb (Is_Anonymous_Access_Type): New routine.
5869 * einfo.ads Update the placement of
5870 E_Anonymous_Access_Subprogram_Type along with all subtypes that
5872 (Is_Anonymous_Access_Type): New routine.
5873 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
5874 master for an access type subject to pragma No_Heap_Finalization.
5875 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
5876 allocated or deallocated does not finalization actions if the
5877 associated access type is subject to pragma No_Heap_Finalization.
5878 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
5879 * par-prag.adb Pragma No_Heap_Finalization does not need special
5880 processing from the parser.
5881 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
5882 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
5883 * sem_prag.adb Add an entry in table Sig_Flags for pragma
5884 No_Heap_Finalization.
5885 (Analyze_Pragma): Add processing for
5886 pragma No_Heap_Finalization. Update various error messages to
5887 use Duplication_Error.
5888 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
5889 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
5890 and corresponding pragma id.
5892 2017-04-25 Bob Duff <duff@adacore.com>
5894 * freeze.adb (Freeze_Record_Type): Use the
5895 underlying type of the component type to determine whether it's
5896 elementary. For representation clause purposes, a private type
5897 should behave the same as its full type.
5898 * fname.ads, fname.adb (Is_Predefined_File_Name):
5899 Make sure things like "system.ali" are recognized as predefined.
5901 2017-04-25 Javier Miranda <miranda@adacore.com>
5903 * debug.adb: Update documentation of -gnatd.6.

5907 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
5908 element iterator when the name is an overloaded function call,
5909 one of whose interpretations yields an array.
5911 2017-04-25 Bob Duff <duff@adacore.com>
5913 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
5914 Is_Internal_Unit_Name): New functions for operating on unit
5915 names, as opposed to file names. There's some duplicated code
5916 with fname.adb, which is unfortunate, but it seems like we don't
5917 want to add dependencies here.
5918 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
5919 to Is_Predefined_Unit_Name; the former was wrong, because Uname
5920 is not a file name at all.
5921 * fname.ads, fname.adb: Document the fact that
5922 Is_Predefined_File_Name and Is_Internal_File_Name can be called
5923 for ALI files, and fix the code so it works properly for ALI
5924 files. E.g. these should return True for "system.ali".
5926 2017-04-25 Justin Squirek <squirek@adacore.com>
5928 * exp_util.adb (Add_Invariant): Removed,
5929 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
5930 and Add_Own_Invariant. (Add_Invariant_Check): Used
5931 for adding runtime checks from any kind of invariant.
5932 (Add_Inherited_Invariant): Generates invariant checks for
5933 class-wide invariants (Add_Interface_Invariants): Removed, code
5934 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
5935 Create a types own invariant procedure (Add_Parent_Invariants):
5936 Removed, code moved to Build_Invariant_Procedure_Body
5937 (Build_Invariant_Procedure_Body): Add refactored calls
5938 and integrated code from Add_Parent_Invariants and
5939 Add_Interface_Invariants.
5940 (Process_Type): Removed, the
5941 relavant code was inlined into both Add_Own_Invariant and
5942 Add_Inherited_Invariant.
5944 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5946 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

5963 and Build_Invariant_Procedure_Declaration.
5964 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
5965 and Build_Invariant_Procedure_Declaration from exp_ch7
5966 and break-out Is_Untagged_Private_Derivation from
5967 Build_Invariant_Procedure_Body.
5968 (Replace_Type_References):
5969 Append an extra parameter to allow for dispatching replacements
5970 and add the corrasponding logic.
5971 (Type_Invariant): Remove
5972 Replace_Typ_Refs and replace its references with calls to
5973 Replace_Type_References.
5974 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
5976 2017-04-25 Bob Duff <duff@adacore.com>
5978 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
5979 that returns True when appropriate.
5980 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
5981 when compiling predefined files.
5982 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
5983 "gnat.adc" should not be considered a predefined file name.
5984 That required (or at least encouraged) a lot of cleanup of global
5985 variable usage. We shouldn't be communicating information via
5986 the global name buffer.
5987 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
5988 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

6008 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
6009 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
6010 Add String_To_Name with no side effects.
6012 2017-04-25 Justin Squirek <squirek@adacore.com>
6014 * sem_ch3.adb (Analyze_Declarations): Add
6015 additional condition for edge case.

6019 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
6020 reserved words inside pragmas. This is necessary to allow the
6021 pragma name Interface to be used in pragma Ignore_Pragma.
6022 * par.adb: Minor comment fix.
6024 2017-04-25 Javier Miranda <miranda@adacore.com>
6026 * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.

6047 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
6048 the first pass over an assignment statement with target names,
6049 to prevent the generation of subtypes (such as discriminated
6050 record components)that may carry the target name outside of the
6051 tree for the assignment. The subtypes will be generated when
6052 the assignment is reanalyzed in full.
6053 (Analyze_Target_Name): Handle properly class-wide types.

6063 and resolve the triaged expression because all substitutions
6064 refer to the proper entities. Update the replacement of

6067 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
6068 are now only processed when freezing occurs. Build a body only

6812 (Check_Dependency_Clause): Properly detect a match between two
6813 'Result attributes. Update the various post-match cases to use

6817 (Remove_Extra_Clauses): New routine.
6818 (Report_Extra_Clauses): Remove the detection of ... => null

6877 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
6878 an object declaration for an array type with a modular index type
6879 with the size of Long_Long_Integer. Special processing is needed
6880 in this case to compute reliably the size of the object, and
6881 eventually to raise Storage_Error, when wrap-around arithmetic
6882 might compute a meangingless size for the object.
6884 2017-01-23 Justin Squirek <squirek@adacore.com>

6891 * sem_res.adb (Resolve_Call): In the part of the code where
6892 it is deciding whether to turn the call into an indexed
6893 component, avoid doing so if the call is to an instance of
6894 Unchecked_Conversion. Otherwise, the compiler turns it into an
6895 indexed component, and resolution of that turns it back into a
6896 function call, and so on, resulting in infinite recursion.
6897 * sem_util.adb (Needs_One_Actual): If the first formal has a
6898 default, then return False.

6943 2017-01-20 Ed Schonberg <schonberg@adacore.com>
6945 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
6946 must be treated as delayed aspect even if the expression is

6969 the prefix is not null) when the prefix denotes an object of an
6970 access type; that is, when there is an implicit dereference.
6972 2017-01-20 Gary Dismukes <dismukes@adacore.com>
6974 * s-rident.ads (constant Profile_Info): Remove

7000 returns a limited view of a type and at the point of the call the
7001 function is not declared in the extended main unit then replace
7002 it with the non-limited view, which must be available. If the
7003 called function is in the extended main unit then no action is
7004 needed since the back-end handles this case.
7006 2017-01-20 Eric Botcazou <ebotcazou@adacore.com>
7008 * sem_ch7.adb (Contains_Subp_Or_Const_Refs): Rename into...

7018 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
7019 base type differs from that of the completion and the private
7020 subtype is an itype (created for a constraint on an access
7021 type e.g.), set Delayed_Freeze on both to prevent out-of-scope
7024 2017-01-20 Hristian Kirtchev <kirtchev@adacore.com>
7026 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
7027 When inheriting the SPARK_Mode of a prior expression function,

7580 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
7581 can have multiple of these tables, so the old and new algorithms
7583 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
7584 parameter of type array. This avoids the global variable, and
7585 allows bounds checking (which is normally defeated by the tables
7586 packages). It also ensures that the Elab_Order is read-only
7588 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
7589 subprograms that need it, as above.
7590 * debug.adb: Document new -dp switch. Modify doc of old -do
7592 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
7593 and Bindgen. Move writing of closure (-R and -Ra switches)
7594 to Binde; that's more convenient.
7596 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7598 * sem_ch6.adb (Analyze_Expression_Function): If the expression
7599 function is a completion, all entities referenced in the
7600 expression are frozen. As a consequence, a reference to an
7601 uncompleted private type from an enclosing scope is illegal.
7603 2017-01-13 Javier Miranda <miranda@adacore.com>
7605 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
7606 (Analyze_Subprogram_Body_Helper): At the occurrence of an
7607 expression function declaration that is a completion, its
7608 expression causes freezing (AI12-0103).
7610 2017-01-13 Vadim Godunko <godunko@adacore.com>
7612 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

7621 * exp_ch3.adb (Default_Initialize_Object): Do not default
7622 initialize an object when it is of a task type and restriction
7623 No_Tasking is in effect because the initialization is obsolete.
7624 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
7625 restriction No_Tasking is in effect.
7626 (Build_Master_Renaming): Do not rename a master when restriction
7627 No_Tasking is in effect.
7629 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7631 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
7632 the legality of An others clause applies as well to a choice in
7633 an Iterated_component_ association.
7634 (Resolve_Iterated_Component_Association): An others choice
7636 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
7637 Iterated_Component_Association is not static.

7641 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
7642 control is passed to the expresion handler before the new mode

7645 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set
7646 in case control is passed to the expresion handler before the

7658 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7660 * sem_util.ads, sem_util.adb (Choice_List): Move function here
7661 from sem_aggr.adb, for use elsewhere.

7663 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
7664 Iterated_Component_Present.
7665 * exp_aggr.adb: Use Choice_List throughout, to handle
7666 Iterated_Component_Associations.
7667 (Gen_Loop): Generate proper loop for an
7668 Iterated_Component_Association: loop variable has the identifier
7669 of the original association. Generate a loop even for a single
7670 component choice, in order to make loop parameter visible in
7672 (Flatten): An Iterated_Component_Association is not static.
7674 2017-01-13 Yannick Moy <moy@adacore.com>
7676 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
7677 float exponentiation for statically known small negative values
7678 is the reciprocal of the exponentiation for the opposite value
7680 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
7681 Ensure that the value of float exponentiation for negative values

7691 expression in delay statement as OK for volatile context.
7693 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7695 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
7696 mode a choice that is a subtype with a static predicate is
7697 replaced by the values it covers. This transformation must not
7698 be performed in ASIS mode, to preserve the source for analysis.
7700 2017-01-13 Justin Squirek <squirek@adacore.com>
7702 * nlists.ads: Correct minor typo.
7704 2017-01-13 Gary Dismukes <dismukes@adacore.com>

7711 Iterated_Component_Association is a named association in an
7713 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
7714 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
7715 and resolve the discrete choices and the expression of the
7717 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
7718 Loop_Actions and Box_Present are attributes of
7719 N_Iterated_Component_Association nodes. Box_Present is always
7721 * sprint.adb (Sprint_Node): An Iterated_Component_Association
7722 has a Discrete_Choices list, as specified in the RM. A
7723 Component_Association for aggregate uses instead a Choices list.
7724 We have to live with this small inconsistency because the new
7725 construct also has a defining identifier, and there is no way
7726 to merge the two node structures.
7728 2017-01-13 Yannick Moy <moy@adacore.com>
7730 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the

7738 Analyze_Declarations, to analyze and resolve the expressions of
7739 aspect specifications in the current declarative list, so that
7740 the expressions have proper entity and type info. This is needed
7741 for ASIS when there is no subsequent expansion to generate this
7742 semantic information.
7743 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
7744 original expression, to suppress cascaded errors when expression
7745 has been constant-folded.
7746 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
7747 ASIS mode, because there is no subsequent expansion to decorate

7753 New function to detect when a call may be inlined or not in
7755 (Expand_Inlined_Call): Ensure that a temporary
7756 is always created in the cases where a type conversion may be
7757 needed on an input parameter in GNATprove mode, so that GNATprove
7758 sees the check to perform.
7759 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
7760 when not applicable due to actual requiring type conversion
7761 with possible check but no temporary value can be copied for
7762 GNATprove to see the check.
