454 2017-09-08 Bob Duff <duff@adacore.com>
456 * s-trasym.ads (Hexa_Traceback): If
457 Suppress_Hex is True, print "..." instead of a hexadecimal
459 * s-trasym.adb: Ignore No_Hex in this version.
462 2017-09-08 Bob Duff <duff@adacore.com>
464 * debug.adb: Minor reformatting.
466 2017-09-08 Bob Duff <duff@adacore.com>
468 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
469 code so it doesn't trigger an "uninit var" warning.
471 2017-09-08 Nicolas Roche <roche@adacore.com>
473 * s-hibaen.ads: Remove obsolete file.
475 2017-09-08 Arnaud Charlet <charlet@adacore.com>
477 * a-locale.ads: Add comment explaining the state of this package.
479 2017-09-08 Arnaud Charlet <charlet@adacore.com>
481 * sem_util.adb (Is_CCT_Instance): Allow calls in the context
483 * sem_prag.ads, sem_prag.adb (Find_Related_Declaration_Or_Body):
484 allow calls in the context of package spec (for pragma
485 Initializes) and bodies (for pragma Refined_State).
487 2017-09-08 Bob Duff <duff@adacore.com>
489 * checks.adb (Insert_Valid_Check): Copy the Do_Range_Check flag to the
492 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
494 * debug.adb (dA): Adjust comment.
495 * gnat1drv.adb (Gnat1drv): Likewise.
496 * opt.ads (List_Representation_Info_Extended): New variable.
497 * repinfo.adb (List_Record_Info): Split implementation into...
498 (Compute_Max_Length): ...this. Recurse on records if requested.
499 (List_Record_Layout): Likewise.
500 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
501 statement, accept '0' and set List_Representation_Info_Extended
503 * usage.adb (Usage): Document new -gnatRe variant.
505 2017-09-08 Ed Schonberg <schonberg@adacore.com>
507 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
508 Do not save the given entity in the global variable Default_Pool
509 if the pragma appears within a generic unit.
511 2017-09-08 Bob Duff <duff@adacore.com>
513 * errout.adb (Delete_Warning): Do not
514 decrement Warnings_Treated_As_Errors. This is called before
515 Warnings_Treated_As_Errors has been incremented to account for
516 this warning. Decrementing it here can lead to negative values
517 of Warnings_Treated_As_Errors, raising Constraint_Error in
518 checks-on builds, and causing the compiler to return an error
519 code in checks-off builds.
521 2017-09-08 Arnaud Charlet <charlet@adacore.com>
523 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
524 entities of named concurrent types as Ref_Id and not of anonymous
525 concurrent objects (because callers already know when a conversion
526 is necessary and can easily do it); also, do not expect protected
527 types or protected objects as Context_Id (because no flow-related
528 SPARK pragmas are attached there); reflect these changes in a
529 more precise comment.
531 2017-09-08 Olivier Hainque <hainque@adacore.com>
533 * g-altive.ads: Add documentation.
535 2017-09-08 Bob Duff <duff@adacore.com>
537 * sem_util.ads, debug.adb: Minor comment fix.
538 * erroutc.ads: Comment fix.
540 2017-09-08 Ed Schonberg <schonberg@adacore.com>
542 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
543 for compatibility of component types of formal and actual in an
544 instantiation of a child unit, when the component type of the
545 formal is itself a formal of an enclosing generic.
547 2017-09-08 Arnaud Charlet <charlet@adacore.com>
549 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
550 sem_prag.adb to make it available for GNATprove; for concurrent
551 types replace custom scope climbing with Scope_Same_Or_Within; for
552 single concurrent objects add scope climbing (with Scope_Within),
553 which was not there (that's the primary semantic change of this
554 commit); also, when comparing a single concurrent object with
555 its corresponding concurrent type rely on equality of types,
556 not of objects (because that's simpler to code).
557 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
558 (Analyze_Global_Item): adjust special-casing of references to the
559 current instance of a concurrent unit in the Global contracts
560 of task types and single tasks objects; similar for references
561 in the protected operations and entries of protected types and
562 single protected objects (in all these cases the current instance
563 behaves as an implicit parameter and must not be mentioned in
564 the Global contract).
566 2017-09-08 Arnaud Charlet <charlet@adacore.com>
568 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
569 function calls returning a record within a subprogram call,
572 2017-09-08 Ed Schonberg <schonberg@adacore.com>
574 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
575 name that designates the current instance of a child unit in its
576 own body and appears as the prefix of a reference to an entity
577 local to the child unit.
578 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
581 2017-09-08 Yannick Moy <moy@adacore.com>
583 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that
586 2017-09-08 Tristan Gingold <gingold@adacore.com>
588 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
589 warnings on internal units in configurable run time mode.
591 2017-09-08 Bob Duff <duff@adacore.com>
593 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
594 representation items from interfaces that the derived type
595 implements, not just from the parent type.
596 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
597 this to return an empty list when there are no interfaces.
598 * einfo.ads, sem_ch13.adb: Minor comment fixes.
599 * sem_attr.adb: Minor comment fix.

608 * exp_ch4.adb (Expand_N_Allocator): Generate a
609 call to Allocate_Any_Controlled when the allocation does not
610 require any initialization.
612 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
614 * sem_util.adb (Copy_Node_With_Replacement):
615 Update the Renamed_Object field of a replicated object renaming
618 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
620 * exp_ch9.adb (Is_Pure_Barrier): Allow type
621 conversions and components of objects. Simplified the detection
622 of the Count attribute by identifying the corresponding run-time
625 2017-09-08 Yannick Moy <moy@adacore.com>
627 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
628 sem_type.adb, sinfo.ads: Minor reformatting.
630 2017-09-08 Ed Schonberg <schonberg@adacore.com>
632 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
633 of Freeze_Profile, used to inhibit the freezing of the profile
634 of an expression function declared within a nested package, when
635 some type in the profile depends on a private type declared in
636 an enclosing package.
638 2017-09-08 Bob Duff <duff@adacore.com>
640 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
641 the subunit case. It's still OK to set it in the "missing subunits"
642 case, because that won't cause the obsolete .ali files that cause
645 2017-09-08 Bob Duff <duff@adacore.com>
647 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
648 unclear why this didn't cause a warning.
649 * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
650 pragmas. It's unclear why this didn't cause an error.
652 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
654 * exp_spark.adb (Expand_SPARK_N_Object_Renaming_Declaration):
656 (Expand_SPARK_Potential_Renaming): Code clean up.

679 for the packed case to the case where it belongs.
680 * sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
681 Also adjust the normalized position of components.
682 (Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise.
684 2017-09-08 Ed Schonberg <schonberg@adacore.com>
686 * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
687 the placement of a primitive operation O that renames an operation
688 R declared in an inner package, and which is thus not a primitive
689 of the dispatching type of O. In this case O is a new primitive
690 and does not inherit its dispatch table position from R (which
693 2017-09-08 Ed Schonberg <schonberg@adacore.com>
695 * sem_dim.adb (Analyze_Dimension_If_Expression,
696 Analyze_Dimension_Case_Expression): new subprograms to verify
697 the dimensional correctness of Ada2012 conditional expressions,
698 and set properly the dimensions of the construct.
699 * sem_res.adb (Resolve_If_Expression, Resolve_Case_Expression)):
700 call Analyze_Dimension.
702 2017-09-08 Ed Schonberg <schonberg@adacore.com>
704 * sem_type.adb (Expand_Interface_Conversion): Prevent an infinite
705 loop on an interface declared as a private extension of another
706 synchronized interface.
708 2017-09-08 Ed Schonberg <schonberg@adacore.com>
710 * sem_ch12.adb (Check_Generic_Parent): New procedure within
711 Analyze_Associations, to handle actual packages that depend on
712 previous instances. If a package IAP that is an instantiation is
713 used as an actual in a subsequent instantiation SI in the same
714 scope, and IAP has a body, IAP must be frozen before SI. If
715 the generic parent of IAP is itself declared in a previous
716 instantiation in the same scope, that instantiation must also

737 * a-wtdeio.adb (Put, all versions): Use Long_Long_Integer
738 (Integer_Value (Item)) when the size of the fixed decimal type
739 is larger than Integer.
741 2017-09-07 Eric Botcazou <ebotcazou@adacore.com>
744 * gcc-interface/decl.c (copy_and_substitute_in_layout): Put the fields
745 in order of increasing position in more cases.

750 on all operations that are modeled as having no read or write
751 of global variables in SPARK.
753 2017-09-07 Raphael Amiard <amiard@adacore.com>
755 * a-chtgop.adb, a-chtgop.ads (Generic_Iteration_With_Position): Added
756 to Hmaps.Generic_Ops.

774 the regressions introduced by the initial version of this patch.
776 2017-09-07 Bob Duff <duff@adacore.com>
778 * sem_ch6.adb (Analyze_Function_Return): Do not
779 insert an explicit conversion to force the displacement of the
780 "this" pointer to reference the secondary dispatch table in the
781 case where the return statement is returning a raise expression,
782 as in "return raise ...".
784 2017-09-07 Arnaud Charlet <charlet@adacore.com>
786 * sem_disp.adb (Is_User_Defined_Equality): Removed procedure.

816 2017-09-07 Ed Schonberg <schonberg@adacore.com>
818 * exp_attr.adb (Expand_N_Attribute_Reference, case 'Constrained):
819 If the prefix is a reference to an object, rewrite it as an
820 explicit dereference, as required by 3.7.2 (2) and as is done
821 with most other attributes whose prefix is an access value.
823 2017-09-07 Bob Duff <duff@adacore.com>
825 * par-ch13.adb: Set the Inside_Depends flag if we are inside a
826 Refined_Depends aspect.

884 * sem_ch10.adb (Remove_Private_With_Clause): If a private with
885 clause for a unit U appears in a context that includes a regular
886 with_clause on U, rewrite the redundant private clause into a null
887 statement, rather than removing it altogether from the context,
888 so that ASIS tools can reconstruct the original source.

892 * sem_ch13.adb (Check_Aspect_At_Freeze_Point): The expression

937 attribute. Defined for record types and subtypes.
938 * exp_ch3.ads (Init_Secondary_Tags): Adding new formal

941 the elaboration of dispatch tables.
942 * exp_ch3.adb (Build_Init_Procedure): Improve the code
943 generated in the IP routines by means of keeping separate
944 the initialization of the object components from the
945 initialization of its dispatch tables. (Init_Secondary_Tags):
946 Adding new formal (Init_Tags_List) and adjusting calls to
947 Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;
948 adjusting also calls to Ada.Tags.Register_Interface_Offset
949 because the type of one of its formals has been changed.
950 * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
951 modified. Instead of receiving a pointer to an object this
952 routine receives now a primary tag.
953 (Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
954 additional formal: the tag of the primary dispatch table.
955 * exp_disp.ads (Elab_Flag_Needed): New subprogram.

966 applied to generic subprograms.
968 2017-09-07 Arnaud Charlet <charlet@adacore.com>
970 * sem_util.adb (Check_Part_Of_Reference): rename Conc_Typ to Conc_Obj

972 fix condition for emitting error message about task/protected type,
974 2017-09-07 Bob Duff <duff@adacore.com>
976 * binde.adb (Debug_Flag_Old): If both -do and -dp
977 are specified, behave as if just -do was specified, rather than

987 * sem_prag.adb (Find_Role): The Global_Seen flag
988 is now consulted not only for abstract states and variables,
989 but for all kinds of items.
990 (Collect_Subprogram_Inputs_Outputs): Do not process formal
991 generic parameters, because unlike ordinary formal parameters,
992 generic formals only act as input/ outputs if they are explicitly
993 mentioned in a Global contract.

1010 derived recor type, copy the dikensions if any of each component
1011 of the parent record to the corresponding component declarations
1012 of the derived record. These expressions are used among other
1013 things as default values in aggregates with box associations.

1030 procedure with misplaced aspect specification, which the parser
1031 first attempts to interpret as a malformed expression function.
1033 2017-09-07 Gary Dismukes <dismukes@adacore.com>

1058 Make_Build_In_Place_Call_In_Anonymous_Context): Do not use the
1059 secondary stack for all functions that return limited tagged
1060 types -- just do it for dispatching calls. Misc cleanup.
1061 * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
1062 remove qualifications and type conversions. Fix various bugs
1063 where only a single level of qualification or conversion was
1064 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
1066 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
1069 2017-09-07 Ed Schonberg <schonberg@adacore.com>

1072 do not create actual subtypes that may generate further predicate
1074 * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
1075 of body is a predicate function as well.
1076 (Resolve_Aspect_Expressions, Resolve_Name): For a component
1077 association, only the expression needs resolution, not the name.
1078 (Resolve_Aspect_Expressions, case Predicates): Construct and
1079 analyze the predicate function declaration in the scope of the
1080 type, before making the type and its discriminants visible.

1123 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
1124 requested. Previously, the -do switch meant "run Elab_New and
1125 Elab_Old and use the order chosen by Elab_Old, possibly with
1126 debugging printouts comparing the two orders." Now it means
1127 "do not run Elab_New." This is of use if there are bugs that
1128 cause Elab_New to crash.

1174 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
1175 entity of a mutable type and the right-hand side is a conditional
1176 expression, resolve the alternatives of the conditional using
1177 the base type of the target entity, because the alternatives
1178 may have distinct subtypes. This is particularly relevant if
1179 the alternatives are aggregates.
1181 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1183 * checks.adb (Apply_Predicate_Check): If the expression is an
1184 aggregate that is the RHS of an assignment, apply the check to
1185 the LHS after the assignment, rather than to the aggregate. This
1186 is more efficient than creating a temporary for the aggregate,
1187 and prevents back-end crashes when the aggregate includes a
1188 dynamic "others' association.

1208 2017-09-06 Gary Dismukes <dismukes@adacore.com>
1210 * errout.adb (Error_Msg): Separate the
1211 treatment for warning vs. style messages in inlinings and
1212 instantiations. Prevents blowups on calls to Warn_Insertion for
1213 style messages, which should not be called in that case because
1214 Warning_Msg_Char is not set.
1216 2017-09-06 Justin Squirek <squirek@adacore.com>

1219 to group all Volatile_Full_Access checks relating to other
1220 representation pragmas (Mark_Component_Or_Object): Created
1221 to centeralize the flagging of attributes for the record type
1222 component case, a pragma applied individually to a component, and

1241 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
1242 that is a proper body corresponding to a stub, we defer the
1243 adjustment of the sloc until after the correct adjustment has
1244 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
1245 the adjustment, because it will be outside the range in (the old,
1246 incorrect) S_Adjustment.
1247 * inline.adb: Use named notation for readability and uniformity.

1269 Linker_Section_Pragma.
1270 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
1271 checking for container loops so that the index cursor is not
1272 directly changable by the user with the use of E_Loop_Parameter.
1273 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.

1318 Generate a freeze node for the actual of a formal package, if
1319 the actual is declared in the same unit and has a corresponding
1320 body, to prevent the current instance from being frozen before
1323 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>

1347 (Strip): New routine.
1349 2017-09-06 Bob Duff <duff@adacore.com>
1351 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
1352 we include the proper header. Otherwise, we just declare the necessary
1353 things from the capabilities library. This is so we can build on
1354 machines without that library, while still enabling that library.
1355 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
1356 simply return 0 if the library is not present, or not included

1372 has no parameter specification and no entry index, use the entry name
1373 as the end of the generated SCO statement.
1375 2017-09-06 Steve Baird <baird@adacore.com>
1377 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
1378 uses of 'Image and related attributes as having side effects in
1379 order to avoid replicating such uses.
1380 * pprint.ads (Expression_Image) Add new generic formal flag
1381 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
1382 (eventually) override the default.
1383 * pprint.adb (Expression_Image) If the new flag is set, then
1384 suppress the ".all" suffix when displaying a dereference whose
1385 prefix is a use of a value-capturing compiler temp of the sort
1386 generated by Expr_Util.Remove_Side_Effects .

1406 * sem_ch3.adb (Derived_Type_Declaration): Use
1407 Incomplete_Or_Partial_View rather than local Find_Partial_View.

1435 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are

1444 2017-09-06 Yannick Moy <moy@adacore.com>
1446 * freeze.adb (Check_Inherited_Conditions): Rewriting
1447 of inherited preconditions and postconditions should only occur
1448 in GNATprove mode, that is, when GNATprove_Mode is True, not to
1449 be confused with SPARK_Mode being On.

1466 (Entity_Table_Size): New constant.
1467 (Entity_Hash): New function.
1468 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
1469 (Is_Subprogram_Ref): Rename into...
1470 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
1471 the table instead of bailing out on them. Scan the value of constants
1472 if it is not known at compile time.
1473 (Contains_Subprograms_Refs): Rename into...
1474 (Scan_Subprogram_Refs): ...this.
1475 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
1476 Is_Public flag on subprograms if they are not actually referenced.
1477 (Hide_Public_Entities): Beef up comment on the algorithm.
1478 Reset the table of subprograms on entry.

1591 that Ada.Command_Line contains modern Ada (the raise expression).
1592 * gnatbind.adb: Avoid dependence on
1593 Ada.Command_Line. Depend on System.Response_File instead

1735 left-hand side, which are invisible in the righ-hand side and
1736 not retrievable as selected components.
1738 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1740 * sem_util.adb (Needs_One_Formal): The first formal of such a

1777 discriminants, the constraint for the target must obtain the
1778 discriminant values from both the operand and from the stored
1779 constraint for it, given that the constrained discriminants are
1780 not visible in the object.
1781 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
1782 side may be derived from that of the left-hand side (as in the
1783 case of an assignment with a change of representation) so the
1784 discriminant to be used in the retrieval of the value of the
1785 component must be the entity in the type of the right-hand side.

1814 in a set membership is an overloaded enumeration literal, and
1815 the type of the alternative is resolved from a previous one,
1816 replace the entity of the alternative as well as the type,
1817 to prevent inconsistencies between the entity and the type.

2360 * exp_ch6.adb (Expand_Call_Helper): When locating the
2361 accessibility entity created for an access parameter, handle
2362 properly a reference to a formal of an enclosing subprogram. if
2363 the reference appears in an inherited class-wide condition, it
2364 is the rewriting of the reference in the ancestor expression,
2365 but the accessibility entity must be that of the current formal.

2369 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

2405 procedure body for a local (sub)type declaration within a
2406 predicate function. Invariant checks do not apply to these, and
2407 the expansion of the procedure will happen in the wrong scope,
2408 leading to misplaced freeze nodes.
2410 2017-05-02 Ed Schonberg <schonberg@adacore.com>
2412 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
2413 to analyze generated actions. If the main unit is a body,

2449 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
2450 Refine predicate for the case where the primitive operation
2451 is a renaming of equality. An overriding operation that is
2452 a user-defined renaming of predefined equality inherits its
2453 slot from the overridden operation. Otherwise it is treated
2454 as a predefined op and occupies the same predefined slot as
2455 equality. A call to it is transformed into a call to its alias,
2456 which is the predefined equality. A dispatching call thus uses
2457 the proper slot if operation is further inherited and called
2458 with class-wide arguments.
2460 2017-05-02 Justin Squirek <squirek@adacore.com>
2462 * errout.adb (Set_Msg_Text): Add a case to switch the message

2474 declaration that operates on some fixed point type.

2495 * exp_ch3.adb (Build_Initialization_Call): Generate a null
2496 statement if the initialization call is a null procedure, as
2497 can happen with a controlled type with no explicit Initialize
2498 procedure, or an array of such.

2500 controlled components that has a trivial Initialize procedure,
2501 insert declaration for finalization counter after object
2503 (Make_Deep_Array_Body, Build_Initialize_statements): Do not create
2504 finalization block and attendant declarations if component has
2505 a trivial Initialize procedure.
2506 (Make_Init_Call): Do not generate a call if controlled type has
2507 a trivial Initialize procedure.

2540 parameter Array_Comp to indicate the case of an array object
2541 with null-excluding components.
2542 * checks.adb (Null_Exclusion_Static_Checks):
2543 Call Compile_Time_Constraint_Error instead of
2544 Apply_Compile_Time_Constraint_Error in the component case. Also
2545 call that when Array_Comp is True, with an appropriate warning for
2546 the array component case. Only create an explicit initialization
2547 by null in the case of an object of a null-excluding access type
2548 (and no longer do that in the component case).
2549 * sem_ch3.adb (Check_Component): Add a Boolean parameter
2550 Array_Comp defaulted to False. Pass Empty for the Comp
2551 actual when calling Null_Exclusion_Static_Checks in the case
2552 where Comp_Decl matches Object_Decl, because we don't have a
2553 component in that case. In the case of an object or component
2554 of an array type, pass True for Array_Comp on the recursive call
2557 2017-05-02 Bob Duff <duff@adacore.com>
2559 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
2560 compute the linux priority from the Ada priority. Call this everywhere
2561 required. In particular, the previous version was not doing this

2600 visibility rules for equality operators that apply within an
2601 instantiation apply within an inlined body.
2602 * sem_type.adb (Add_One_Interp): ditto.
2604 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>

2632 * opt.ads: Add missing GNAT markers in comments.
2633 * opt.adb (Set_Opt_Config_Switches): Do not override earlier
2634 settings of Optimize_Alignment at the end.
2636 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
2638 * checks.adb (Apply_Constraint_Check): Do not apply
2639 a discriminant check when the associated type is a constrained
2640 subtype created for an unconstrained nominal type.
2641 * exp_attr.adb: Minor reformatting.
2643 2017-05-02 Bob Duff <duff@adacore.com>

2668 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
2670 2017-05-02 Bob Duff <duff@adacore.com>
2672 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
2673 to find primitive ops, instead of using an Identifier that will
2674 later be looked up. This is necessary because these ops are not
2675 necessarily visible at all places where we need to call them.
2676 * exp_util.ads: Minor comment fix.
2678 2017-05-02 Ed Schonberg <schonberg@adacore.com>
2680 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
2681 references are fully conformant if they are both expansions
2682 of the discriminant of a protected type, within one of the
2683 protected operations. One occurrence may be expanded into a
2684 constant declaration while the other is an input parameter to
2685 the corresponding generated subprogram.

2715 array components specially.
2717 2017-05-02 Ed Schonberg <schonberg@adacore.com>
2719 * sem_ch8.adb (Premature_Usage): If the premature usage of
2720 an entity is as the expression in its own object decaration,
2721 rewrite the reference as Any_Id to prevent cascaded errors or
2722 compiler loops when such an entity is used in an address clause.
2724 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
2726 * gcc-interface/decl.c (components_to_record): Add missing guard.

2731 Put back pending fields onto the regular list if the misalignment
2732 happens to cancel itself.
2734 2017-04-28 Ed Schonberg <schonberg@adacore.com>
2736 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
2737 controlling actual in a prefixed call, preserve the original node
2738 information if the prefix itself has been rewritten, for ASIS use.
2740 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
2742 * exp_ch6.adb (Insert_Post_Call_Actions):
2743 Code clean up. Insert the post-call actions after an enclosing
2744 procedure call when N denotes a function call and appears as an
2745 actual parameter in the procedure call.
2747 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
2749 * freeze.adb (Check_Component_Storage_Order): If there is a clause
2750 for the component, also reject the attribute if the component
2751 doesn't end on a byte boundary and its scalar storage order is
2752 different from that of the enclosing record type.
2754 2017-04-28 Javier Miranda <miranda@adacore.com>
2756 * atree.ads (Info_Messages): Removed.

2788 * sem_util.ads, sem_util.adb (Might_Raise): New function
2789 that replaces Is_Exception_Safe, but has the opposite
2790 sense. Is_Exception_Safe was missing various cases -- calls inside
2791 a pragma Debug, calls inside an 'if' or assignment statement,
2792 etc. Might_Raise now walks the entire subtree looking for things
2794 * exp_ch9.adb (Is_Exception_Safe): Remove.
2795 (Build_Protected_Subprogram_Body): Replace call to
2796 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
2797 constants where possible).
2798 * exp_ch7.adb: Rename Is_Protected_Body -->
2799 Is_Protected_Subp_Body. A protected_body is something different

2828 * sem_ch13.adb (Analyze_Aspect_Specifications, case
2829 Interrupt_Handler and Attach_Handler): Generate reference
2830 to protected operation to prevent spurious warnings about

2834 2017-04-28 Ed Schonberg <schonberg@adacore.com>
2836 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
2837 that follows an expression function must not be relocated to
2838 the generated body, because it applies to the code that follows.
2840 2017-04-28 Gary Dismukes <dismukes@adacore.com>
2842 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
2843 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
2844 code that might violate the more stringent checking for 'Access
2845 introduced in Ada 2005.
2847 2017-04-28 Arnaud Charlet <charlet@adacore.com>
2849 * a-cforse.adb: minor style fix in comment.
2851 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
2853 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also

2869 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
2870 node between access types, freeze the designated type as well,
2871 so that dispatch table pointers are created in the proper scope,

2874 2017-04-28 Bob Duff <duff@adacore.com>
2876 * alloc.ads (Nodes_Initial): Go back to previous value. The large
2877 value makes large compilations faster, but small compilations slower.
2879 2017-04-28 Arnaud Charlet <charlet@adacore.com>
2881 * sem_util.adb: minor typos in Is_Child_Or_Sibling.

2899 2017-04-28 Ed Schonberg <schonberg@adacore.com>
2901 * sem_res.adb (In_Instance_Code): New predicate in
2902 Valid_Conversion, to determine whether a type conversion appears
2903 as (or within) an actual for a formal object. Type conversions
2904 in instances are not rechecked in Valid_Conversion because
2905 visibility changes between generic location andi instance may
2906 lead to spurious errors, but conversions within an actual must be
2907 fully checked, and they are not fully resolved when pre-analyzing
2910 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
2912 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
2913 New_Copy_Tree instead of Relocate_Node as any subsequent copies
2914 of the relocated node will have mangled Parent pointers.
2915 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
2916 tables used in conjunction with entity and itype replication.
2917 (Visit_Entity): Rewrite the restriction on which entities

2954 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
2955 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
2956 components_to_record.
2957 (gnu_field_to_gnat): New function.
2958 (warn_on_field_placement): Likewise.
2959 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
2960 parameters. Rename local variables and adjust recursive call.
2961 Rework final scan of the field list and implement warnings on the
2962 problematic placement of specific sorts of fields.

2972 For efficiency, cache results of Is_Internal_File_Name and
2973 Is_Predefined_File_Name in the Units table. This avoids a lot
2974 of repeated text processing.
2976 2017-04-27 Emmanuel Briot <briot@adacore.com>

3005 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3007 * exp_util.adb (Replace_Entity): The prefix of a 'Result
3008 attribute reference in a post- condition is the subprogram to
3009 which the condition applies. If the condition is inherited
3010 by a type extension, the prefix becomes a reference to the
3011 inherited operation, but there is no need to create a wrapper
3012 for this operation, because 'Result is expanded independently
3013 when elaborating the postconditions.

3025 Remove unused function.
3026 * alloc.ads (Nodes_Initial): Use a much larger value, because
3027 the compiler was spending a lot of time copying the nodes table
3028 when it grows. This number was chosen in 1996, so is rather out
3029 of date with current memory sizes. Anyway, it's virtual memory.
3030 Get rid of Orig_Nodes_...; use Node_... instead.
3031 * atree.adb (Lock): Do not release the Nodes tables; it's a
3033 Orig_Nodes_ ==> Nodes_
3034 * nlists.adb: Orig_Nodes_ ==> Nodes_
3035 * g-table.adb: Remove unused "with" clause.
3036 * g-table.ads, table.ads: Remove Big_Table_Type, which should

3079 of Expand_Dispatching_Call. If the denoted subprogram has a
3080 class-wide precondition, this is the only precondition that
3081 applies to the call, rather that the class-wide preconditions
3082 that may apply to the body that is executed. (This is specified

3099 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
3100 prefix can be an object reference in which case Obj'Image (X)
3101 can only be interpreted as an indexing of the parameterless
3102 version of the attribute.
3103 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
3104 an indexing or a slice operation if the attribute does not require
3105 parameters. In Ada2012 'Image also belongs in this category,
3106 and A'Image (lo .. hi) is legal and must be parsed as a slice.
3108 2017-04-27 Yannick Moy <moy@adacore.com>
3110 * exp_ch4.adb: Minor reformatting.
3111 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,

3767 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
3768 to manage the secondary stack when an enclosing scope already
3769 performs this functionality (aka relaxed management). Switch
3770 -gnatd.s may be used to force strict management in which case
3771 the block will manage the secondary stack unconditionally. Add
3772 a guard to stop the traversal when encountering a package or a

3777 * sem_res.adb (Resolve_Call): Refine further the handling of
3778 limited views of return types in function calls. If the function
3779 that returns a limited view appears in the current unit,
3780 we do not replace its type by the non-limited view because
3781 this transformation is performed int the back-end. However,
3782 the type of the call itself must be the non-limited view, to
3783 prevent spurious resolution errors.
3785 2017-04-27 Ed Schonberg <schonberg@adacore.com>
3787 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
3788 Removed, proposed implementation using generics for class-wide

3790 (Class_Wide_Clone): New attribute of subprogram. Designates
3791 subprogram created for primitive operations with class-wide
3792 pre/postconditions that contain calls to other primitives. The
3793 clone holds the body of the original primitive, but the
3794 pre/postonditions do not apply to it. The original body is
3795 rewritten as a wrapper for a call to the clone.
3796 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
3797 the flag is set, no code for the corresponding pre/postconditions
3798 is inserted into its body.
3800 2017-04-27 Bob Duff <duff@adacore.com>

3853 child of Ada.Containers. It provides functional indefinite unbounded
3854 sets which can be used as high level models for specification

3870 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
3871 point type actual that has user-defined arithmetic primitives,
3872 when there is a previous actual for a formal package that defines
3873 a fixed-point type with the parent user-defined operator.

3889 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
3890 dimensions of operands if node has been analyzed already, because
3891 previous analysis and dimension checking will have removed the
3892 dimension information from the operands.

3896 * debug.adb: Document the use of switch -gnatd.s.
3897 * einfo.ads Update the documentation on attribute

3986 Move Set_Source_File_Index_Table into the private part, because
3987 it is used only in the body and in children. Use trickery to
3988 modify the dope in the generic instantiation case. It's ugly,
3989 but not as ugly as the previous method. Fix documentation.

4006 expander is not active or when index/range checks are suppressed
4008 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
4009 Remove variants that include a Supress parameter. These routines
4010 are never used, and were introduced before the current scope-based
4011 check suppression method.

4063 the Internal_Source buffer. This removes the incorrect call to "="
4064 the customer noticed.
4065 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
4066 eventually need to eliminate them altogether. Or else get rid
4067 of zero-origin addressing.

4490 2017-04-25 Ed Schonberg <schonberg@adacore.com>
4492 * sem_ch6.adb (Conforming_Types): If type of formal as a specified
4493 dimension system, verify that dimensions of both match.
4494 (Check_Conformance): Add error message in case of dimension
4496 * sem_dim.ads, sem_dim.adb (Dimensions_Match): New utility
4499 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

4509 2017-04-25 Claire Dross <dross@adacore.com>
4511 * sem_prag.adb (Collect_Inherited_Class_Wide_Conditions): Go to
4512 ultimate alias when accessing overridden operation. Indeed, if the
4513 overridden operation is itself inherited, it won't have any explicit
4516 2017-04-25 Ed Schonberg <schonberg@adacore.com>
4518 * sem_warn.adb (Warn_On_Overlapping_Actuals): There can be no
4519 overlap if the two formals have different types, because formally
4520 the corresponding actuals cannot designate the same objects.
4522 2017-04-25 Ed Schonberg <schonberg@adacore.com>
4524 * sem_dim.adb (Dimensions_Of_Operand): minot cleanups: a) If
4525 dimensions are present from context, use them. b) If operand is
4526 a static constant rewritten as a literal, obtain the dimensions
4527 from the original declaration, otherwise use dimensions of type
4528 established from context.
4530 2017-04-25 Yannick Moy <moy@adacore.com>
4532 * sem_util.adb (Is_Effectively_Volatile): Protect against base type

4545 2017-04-25 Ed Schonberg <schonberg@adacore.com>
4547 * sem_disp.adb (Check_Dispatching_Context): Add guard to refine
4548 the check that recognizes a call to a private overridding and
4549 replaces the called subprogram with its alias.
4551 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
4553 * exp_util.adb: Minor reformatting.
4555 2017-04-25 Justin Squirek <squirek@adacore.com>
4557 * exp_ch3.adb (Freeze_Type): Add condition to always treat
4558 interface types as a partial view of a private type for the
4559 generation of invariant procedure bodies.
4560 * exp_util.adb, exp_util.ads (Add_Inherited_Invariants):
4561 Add a condition to get the Corresponding_Record_Type for
4562 concurrent types, add condition to return in the absence of a
4563 class in the pragma, remove call to Replace_Type_References,
4564 and add call to Replace_References.
4565 (Add_Interface_Invariatns),
4566 (Add_Parent_Invariants): Modify call to Add_Inherited_Invariants
4567 to including the working type T.
4568 (Add_Own_Invariants): Remove
4569 legacy condition for separate units, remove dispatching for ASIS
4570 and save a copy of the expression in the pragma expression.
4571 (Build_Invariant_Procedure_Body): Default initalize vars,
4572 remove return condition on interfaces, always use the
4573 private type for interfaces, and move the processing of types
4574 until after the processing of invariants for the full view.
4575 (Build_Invariant_Procedure_Declaration): Remove condition
4576 to return if an interface type is encountered and add
4577 condition to convert the formal parameter to its class-wide
4578 counterpart if Work_Typ is abstract.
4579 (Replace_Type): Add call to Remove_Controlling_Arguments.
4580 (Replace_Type_Ref): Remove class-wide dispatching for the current
4581 instance of the type.
4582 (Replace_Type_References): Remove parameter "Derived"
4583 (Remove_Controlling_Arguments): Created in order to removing
4584 the controlliong argument from calls to primitives in the case
4585 of the formal parameter being an class-wide abstract type.
4586 * sem_ch3.adb (Build_Assertion_Bodies_For_Type): Almost identical
4587 to the change made to Freeze_Type in exp_ch3. Add a condition
4588 to treat interface types as a partial view.
4589 * sem_prag.adb (Analyze_Pragma): Modify parameters in the call
4590 to Build_Invariant_Procedure_Declaration to properly generate a
4591 "partial" invariant procedure when Typ is an interface.

4595 * a-numeri.ads: Go back to using brackets encoding for the Greek
4598 2017-04-25 Ed Schonberg <schonberg@adacore.com>
4600 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
4601 (10-15): if derived type T with progenitors is abstract,
4602 and primitive P of this type inherits non-trivial classwide
4603 preconditions from both a parent operation and from an interface
4604 operation, then the inherited operation is abstract if the parent
4605 operation is not null.
4606 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
4607 with Covered_Interface_Op to yield the actual interface operation
4608 that is implemented by a given inherited operation.
4610 2017-04-25 Javier Miranda <miranda@adacore.com>
4612 * exp_ch4.adb (Expand_N_Op_Expon): Relocate left
4613 and right operands after performing the validity checks. Required
4614 because validity checks may remove side effects from the operands.
4616 2017-04-25 Javier Miranda <miranda@adacore.com>
4618 * exp_attr.adb (Attribute_Unrestricted_Access):
4619 Do not disable implicit type conversion. Required to generate
4620 code that displaces the pointer to reference the secondary
4623 2017-04-25 Pascal Obry <obry@adacore.com>
4625 * prj-attr.adb, snames.ads-tmpl: Add package Install's
4626 Required_Artifacts attribute.
4628 2017-04-25 Ed Schonberg <schonberg@adacore.com>
4630 * sem_util.adb (Same_Value): String literals are compile-time
4631 values, and comparing them must use Expr_Value_S.
4633 2017-04-25 Ed Schonberg <schonberg@adacore.com>
4635 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
4636 dereference is introduced for the object, and the object is
4637 overloaded, do not check whether it is aliased, because it may
4638 include an implicit dereference.
4639 * sem_type.adb (Disambiguate): If two interpretations are access
4640 attribute types with the same designated type keep either of
4641 them and do not report an ambiguity. A true ambiguity will be
4644 2017-04-25 Bob Duff <duff@adacore.com>
4646 * a-numeri.ads: Change the encoding of Greek letter Pi from
4647 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
4648 to indicate the encoding. We considered using a byte order mark
4649 (BOM), but that causes various trouble (misc software eats the
4650 BOM, if you have a patch with a BOM, then it's not at the start
4651 of the patch, so it's not a BOM, the BOM affects with-ing files,
4653 * scng.adb, s-wchcnv.adb: Minor.

4665 moved here from sem_ch3.
4666 * sem_ch8.adb (Analyze_Subprogram_Renaming): Implement legality
4667 check given in RM 6.1.1 (17) concerning renamings of overriding
4668 operations that inherits class-wide preconditions from ancestor

4689 restrictions when the handler is internally generated and the
4692 2017-04-25 Ed Schonberg <schonberg@adacore.com>
4694 * sem_ch3.adb (Has_Non_Trivial_Precondition): New predicate to
4695 enforce legality rule on classwide preconditions inherited from
4696 both an ancestor and a progenitor (RM 6.1.1 (10-13).
4697 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
4698 subprogram need not be dispatching if it appears in a precondition
4699 for an abstract or null subprogram.
4701 2017-04-25 Gary Dismukes <dismukes@adacore.com>
4703 * sem_ch10.adb: Minor typo fix.
4705 2017-04-25 Arnaud Charlet <charlet@adacore.com>
4707 * gcc-interface/Makefile.in: Cleanup VxWorks targets.
4709 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
4711 * fname.adb (Is_Internal_File_Name): Arrange for the slices to
4712 have a length which is a power of 2.
4713 (Is_Predefined_File_Name): Likewise. Adjust comment.
4715 2017-04-25 Bob Duff <duff@adacore.com>
4717 * exp_aggr.adb (Component_Count): Protect the
4718 arithmetic from attempting to convert a value >= 2**31 to Int,
4719 which would otherwise raise Constraint_Error.
4721 2017-04-25 Bob Duff <duff@adacore.com>
4723 * opt.ads (Locking_Policy): Fix incorrect documentation. The
4724 first character of the policy name is not unique.
4726 2017-04-25 Bob Duff <duff@adacore.com>
4728 * s-fileio.adb (Name): Raise Use_Error if the file is a temp file.
4729 * s-ficobl.ads (Is_Temporary_File): Remove incorrect comment
4730 about this flag not being used. It was already used, and it is

4747 Save and restore the value of global flag
4748 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value
4749 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance when either
4750 the corresponding spec or the body must ignore all SPARK_Mode
4751 pragmas found within.
4752 (Analyze_Subprogram_Declaration): Mark
4753 the spec when it needs to ignore all SPARK_Mode pragmas found
4754 within to allow the body to infer this property in case it is
4755 instantiated or inlined later.
4756 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
4757 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
4758 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
4759 when the corresponding spec also ignored all SPARK_Mode pragmas
4761 (Analyze_Package_Declaration): Mark the spec when
4762 it needs to ignore all SPARK_Mode pragmas found within to allow
4763 the body to infer this property in case it is instantiated or
4765 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
4766 Save and restore the value of flag
4767 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
4768 formal spec when it needs to ignore all SPARK_Mode
4769 pragmas found within to allow the body to infer this
4770 property in case it is instantiated or inlined later.
4771 (Analyze_Package_Instantiation): Save and restore the value
4772 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
4773 the instance spec when it needs to ignore all SPARK_Mode
4774 pragmas found within to allow the body to infer this
4775 property in case it is instantiated or inlined later.

4777 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
4778 instance spec and anonymous package when they need to ignore
4779 all SPARK_Mode pragmas found within to allow the body to infer
4780 this property in case it is instantiated or inlined later.
4781 (Instantiate_Package_Body): Save and restore the value of global
4782 flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set the value of

4792 Ignore_Pragma_SPARK_Mode.
4793 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
4794 all SPARK_Mode pragmas defined within yields mode "off".
4796 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
4798 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.
4800 2017-04-25 Bob Duff <duff@adacore.com>
4802 * exp_atag.adb (Build_CW_Membership): Add "Suppress =>
4803 All_Checks" to avoid generating unnecessary checks.

4813 * s-taprop-linux.adb: Minor editorial fixes.
4815 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
4817 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
4818 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
4819 variable and set it to True whenever the main hash table is
4820 populated. Short- circuit the Assoc function if it is false
4821 and add associated guards.
4823 2017-04-25 Olivier Hainque <hainque@adacore.com>
4825 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
4826 specs without elaboration code that have an elaboration counter
4827 nevertheless, e.g. when compiled with -fpreserve-control-flow.
4828 * sem_ch10.adb (Analyze_Compilation_Unit):
4829 Set_Elaboration_Entity_Required when requested to preserve
4830 control flow, to ensure the unit elaboration is materialized at
4831 bind time, resulting in the inclusion of the unit object file
4832 in the executable closure at link time.
4834 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
4836 * exp_dbug.adb: In Debug_Renaming_Declaration,
4837 when dealing with indexed component, accept to produce a renaming
4838 symbol when the index is an IN parameter or when it is a name
4839 defined in an outer scope.
4841 2017-04-25 Yannick Moy <moy@adacore.com>
4843 * errout.adb (Error_Msg): Adapt continuation
4844 message in instantiations and inlined bodies for info messages.
4846 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
4848 * fname.adb (Has_Internal_Extension): Add pragma Inline.
4849 Use direct 4-character slice comparisons.
4851 pragma Inline. (Has_Suffix): Delete.
4852 (Is_Internal_File_Name):
4853 Test Is_Predefined_File_Name first.
4854 (Is_Predefined_File_Name):
4855 Use direct slice comparisons as much as possible and limit all
4856 comparisons to at most 8 characters.
4858 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
4860 * checks.adb (Insert_Valid_Check): Code cleanup.
4861 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
4862 (Expand_Actuals): Generate proper copy-back for a validation
4863 variable when it acts as the argument of a type conversion.
4864 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
4865 predicate to operate on type qualifications.
4867 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
4869 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
4872 2017-04-25 Bob Duff <duff@adacore.com>
4874 * sem_prag.adb (No_Return): Give an error if the pragma applies
4875 to a body. Specialize the error for the specless body case,
4876 as is done for (e.g.) pragma Convention.
4877 * debug.adb: Add switch -gnatd.J to disable the above legality
4878 checks. This is mainly for use in our test suite, to avoid
4879 rewriting a lot of illegal (but working) code. It might also
4880 be useful to customers. Under this switch, if a pragma No_Return
4881 applies to a body, and the procedure raises an exception (as it
4882 should), the pragma has no effect. If the procedure does return,
4883 execution is erroneous.
4885 2017-04-25 Bob Duff <duff@adacore.com>
4887 * exp_ch6.adb (Expand_Actuals): This is the
4888 root of the problem. It took N as an 'in out' parameter, and in
4889 some cases, rewrote N, but then set N to Original_Node(N). So
4890 the node returned in N had no Parent. The caller continued
4891 processing of this orphaned node. In some cases that caused a
4892 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
4893 and trips over the Empty Parent). The solution is to make N an
4894 'in' parameter. Instead of rewriting it, return the list of
4895 post-call actions, so the caller can do the rewriting later,
4896 after N has been fully processed.
4897 (Expand_Call_Helper): Move most of Expand_Call here. It has
4898 too many premature 'return' statements, and we want to do the
4899 rewriting on return.
4900 (Insert_Post_Call_Actions): New procedure to insert the post-call
4901 actions in the appropriate place. In the problematic case,
4902 that involves rewriting N as an Expression_With_Actions.
4903 (Expand_Call): Call the new procedures Expand_Call_Helper and
4904 Insert_Post_Call_Actions.
4906 2017-04-25 Ed Schonberg <schonberg@adacore.com>
4908 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
4909 properly type derived from generic formal types, to handle
4910 properly modified version of ACATS 4.1B B611017.
4912 2017-04-25 Javier Miranda <miranda@adacore.com>
4914 * exp_unst.adb (Subp_Index): Adding missing
4915 support for renamings and functions that return a constrained
4916 array type (i.e. functions for which the frontend built a
4917 procedure with an extra out parameter).
4919 2017-04-25 Pascal Obry <obry@adacore.com>
4921 * s-string.adb: Minor code clean-up.
4923 2017-04-25 Bob Duff <duff@adacore.com>

4927 * adaint.h, adaint.c (__gnat_portable_no_block_wait): C support
4928 function for Non_Blocking_Wait_Process.
4930 2017-04-25 Bob Duff <duff@adacore.com>
4932 * prep.adb (Preprocess): Remove incorrect
4933 Assert. Current character can be ASCII.CR.
4935 2017-04-25 Ed Schonberg <schonberg@adacore.com>
4937 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
4938 convention Stdcall, which has a number of exceptions. Convention
4939 is legal on a component declaration whose type is an anonymous
4940 access to subprogram.
4942 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
4944 * sem_ch4.adb: sem_ch4.adb Various reformattings.
4945 (Try_One_Prefix_Interpretation): Use the base type when dealing
4946 with a subtype created for purposes of constraining a private
4947 type with discriminants.
4949 2017-04-25 Javier Miranda <miranda@adacore.com>
4951 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.
4952 * warnsw.ads, warnsw.adb (All_Warnings): Set warning on late
4953 dispatching primitives (Restore_Warnings): Restore warning on
4954 late dispatching primitives (Save_Warnings): Save warning on late
4955 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
4956 to enable/disable this warning.
4957 (WA_Warnings): Set warning on late dispatching primitives.
4958 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
4959 that its parent type has a private extension.
4960 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
4962 * usage.adb: Document -gnatw.j and -gnatw.J.
4964 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
4966 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
4969 2017-04-25 Bob Duff <duff@adacore.com>
4971 * binde.adb (Validate): Do not pass dynamic strings
4972 to pragma Assert, because older compilers do not support that.
4974 2017-04-25 Bob Duff <duff@adacore.com>
4976 * s-fileio.adb (Close): When a temp file is
4977 closed, delete it and clean up its Temp_File_Record immediately,
4978 rather than waiting until later.
4979 (Temp_File_Record): Add File
4980 component, so Close can know which Temp_File_Record corresponds
4981 to the file being closed.
4982 (Delete): Don't delete temp files,
4983 because they are deleted by Close.
4984 (Open): Set the File component
4985 of Temp_File_Record. This requires moving the creation of the
4986 Temp_File_Record to the end, after the AFCB has been created.
4988 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
4990 * checks.adb (Insert_Valid_Check): Do not generate
4991 a validity check when inside a generic.

5015 conversions from float to integer in GNATprove mode.
5016 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
5017 to call Apply_Type_Conversion_Checks, so that range checks
5018 are properly positioned when needed on conversions, including
5019 when converting from float to integer. (Determine_Range): In
5020 GNATprove mode, take into account the possibility of conversion
5021 from float to integer.
5022 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
5023 check on conversions from fixed-point to integer, not anymore
5024 on conversions from floating-point to integer, when in GNATprove
5027 2017-04-25 Yannick Moy <moy@adacore.com>
5029 * checks.adb (Determine_Range_R): Special case type conversions
5030 from integer to float in order to get bounds in that case too.
5031 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
5032 mode, for computations involved in interval checking.

5046 * exp_attr.adb (Make_Range_Test): Add processing for validation
5047 variables to avoid extra reads and copies of the prefix.

5049 variables in order to reflect any changes done in the variable
5050 back into the original object.

5066 Pre'Class aspect is specified for the corresponding primitive
5067 subprogram of some ancestor of T.
5069 2017-04-25 Bob Duff <duff@adacore.com>
5071 * sem_ch8.adb (Use_One_Type): If a use_type_clause
5072 is redundant, set its Used_Operations to empty. This is only
5073 necessary for use clauses that appear in the parent of a generic
5074 child unit, because those use clauses get reanalyzed when we
5075 instantiate the generic, and we don't want the Used_Operations
5076 carried over from the original context (where it was probably

5092 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5094 * sem_ch8.adb (Find_Type): For an attribute reference
5095 'Class, if prefix type is synchronized and previous errors
5096 have suppressed the creation of the corresponding record type,
5097 create a spurious class-wide for the synchonized type itself,
5098 to catch other misuses of the attribute
5100 2017-04-25 Steve Baird <baird@adacore.com>
5102 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
5103 is True, then don't generate the accessibility check for the
5104 tag of a tagged result.

5107 tag checks for the result of call to an instance of
5108 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
5109 descendant of" check and the accessibility check).
5111 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5113 * sem_ch13.adb: Code cleanups.
5114 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

5120 (Expand_Concatenate): When optimization is enabled, also expand
5121 the operation out-of-line if the concatenation is present within
5122 the expression of the declaration of a library-level object and
5123 not only if it is the expression of the declaration.
5125 2017-04-25 Bob Duff <duff@adacore.com>
5127 * freeze.adb (Freeze_Object_Declaration): Do
5128 not Remove_Side_Effects if there is a pragma Linker_Section,
5129 because in that case we want static initialization in the
5130 appropriate section.
5132 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5134 * exp_dbug.adb: Minor rewording and reformatting.
5136 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5138 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
5139 handle the proposed changes to rules concerning potentially
5140 unevaluated expressions, to include selected components that
5141 do not depend on discriminants, and indexed components with
5143 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
5144 predicate in quantified expression, and fix bugs in the handling
5145 of case expressions and membership test.

5163 renaming entity for debug information, mark the entity as needing debug
5164 info if it comes from sources.
5166 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5168 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the

5188 internal calls that appear in preconditions of protected
5189 operations, in default values for same, and in contract guards

5201 * a-numaux-x86.ads: Fix package description.
5202 * a-numaux-x86.adb (Is_Nan): Minor tweak.
5203 (Reduce): Adjust and complete description. Call Is_Nan instead of
5204 testing manually. Use an integer temporary to hold rounded value.
5205 * a-numaux-darwin.adb (Reduce): Likewise.
5206 (Is_Nan): New function.
5208 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5210 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
5211 on analysis of prefix whose type is a current instance of a
5212 synchronized type, but where the prefix itself is an entity that

5217 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
5218 the identity of callable entities therein, because they have been
5219 properly resolved, and prefixed calls may have been rewritten
5222 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
5224 * exp_ch3.adb (Build_Init_Statements): Convert
5225 the expression of the pragma/aspect Secondary_Stack_Size to

5238 * s-osinte-freebsd.ads: Minor comment tweaks
5240 2017-04-25 Javier Miranda <miranda@adacore.com>
5242 * urealp.adb (UR_Write): Reverse previous patch
5243 adding documentation on why we generate multiplications instead
5244 of divisions (needed to avoid expressions whose computation with
5245 large numbers may cause division by 0).
5247 2017-04-25 Bob Duff <duff@adacore.com>
5249 * erroutc.adb (Set_Specific_Warning_Off,
5250 Set_Warnings_Mode_Off): Use the correct source file for
5251 Stop. Was using Current_Source_File, which is only valid during
5252 parsing. Current_Source_File will have a leftover value from
5253 whatever file happened to be parsed last, because of a with_clause
5256 2017-04-25 Bob Duff <duff@adacore.com>
5258 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
5259 to In_Predefined_Unit, but including GNAT units.
5260 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
5261 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
5262 because Should_Ignore_Pragma was not working reliably outside
5263 the parser, because Current_Source_File is not valid.
5264 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
5265 * par-prag.adb: Call Should_Ignore_Pragma_Par.

5329 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
5332 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5334 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
5335 of prefix whose type is a current instance of a synchronized
5336 type. If the prefix is an object this is an external call (or
5337 requeue) that can only access public operations of the object. The
5338 previous predicate was too restrictive, and did not allow public
5339 protected operations, only task entries.
5341 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5343 * sem_ch5.adb, fname.adb: Minor reformatting.
5345 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

5349 E_Anonymous_Access_Subprogram_Type along with all subtypes that
5351 (Is_Anonymous_Access_Type): New routine.
5352 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
5353 master for an access type subject to pragma No_Heap_Finalization.
5354 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
5355 allocated or deallocated does not finalization actions if the
5356 associated access type is subject to pragma No_Heap_Finalization.
5357 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
5358 * par-prag.adb Pragma No_Heap_Finalization does not need special
5359 processing from the parser.
5360 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
5361 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
5362 * sem_prag.adb Add an entry in table Sig_Flags for pragma

5364 (Analyze_Pragma): Add processing for

5373 * freeze.adb (Freeze_Record_Type): Use the
5374 underlying type of the component type to determine whether it's
5375 elementary. For representation clause purposes, a private type
5376 should behave the same as its full type.
5377 * fname.ads, fname.adb (Is_Predefined_File_Name):
5378 Make sure things like "system.ali" are recognized as predefined.
5380 2017-04-25 Javier Miranda <miranda@adacore.com>

5386 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
5387 element iterator when the name is an overloaded function call,
5388 one of whose interpretations yields an array.
5390 2017-04-25 Bob Duff <duff@adacore.com>
5392 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
5393 Is_Internal_Unit_Name): New functions for operating on unit
5394 names, as opposed to file names. There's some duplicated code
5395 with fname.adb, which is unfortunate, but it seems like we don't
5396 want to add dependencies here.
5397 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
5398 to Is_Predefined_Unit_Name; the former was wrong, because Uname
5399 is not a file name at all.
5400 * fname.ads, fname.adb: Document the fact that
5401 Is_Predefined_File_Name and Is_Internal_File_Name can be called
5402 for ALI files, and fix the code so it works properly for ALI
5403 files. E.g. these should return True for "system.ali".
5405 2017-04-25 Justin Squirek <squirek@adacore.com>
5407 * exp_util.adb (Add_Invariant): Removed,
5408 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
5409 and Add_Own_Invariant. (Add_Invariant_Check): Used
5410 for adding runtime checks from any kind of invariant.
5411 (Add_Inherited_Invariant): Generates invariant checks for
5412 class-wide invariants (Add_Interface_Invariants): Removed, code
5413 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
5414 Create a types own invariant procedure (Add_Parent_Invariants):
5415 Removed, code moved to Build_Invariant_Procedure_Body
5416 (Build_Invariant_Procedure_Body): Add refactored calls
5417 and integrated code from Add_Parent_Invariants and
5418 Add_Interface_Invariants.
5419 (Process_Type): Removed, the
5420 relavant code was inlined into both Add_Own_Invariant and
5421 Add_Inherited_Invariant.
5423 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5425 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

5442 and Build_Invariant_Procedure_Declaration.
5443 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
5444 and Build_Invariant_Procedure_Declaration from exp_ch7
5445 and break-out Is_Untagged_Private_Derivation from
5446 Build_Invariant_Procedure_Body.
5447 (Replace_Type_References):
5448 Append an extra parameter to allow for dispatching replacements
5449 and add the corrasponding logic.
5450 (Type_Invariant): Remove
5451 Replace_Typ_Refs and replace its references with calls to
5452 Replace_Type_References.
5453 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
5455 2017-04-25 Bob Duff <duff@adacore.com>
5457 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
5458 that returns True when appropriate.
5459 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
5460 when compiling predefined files.
5461 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
5462 "gnat.adc" should not be considered a predefined file name.
5463 That required (or at least encouraged) a lot of cleanup of global
5464 variable usage. We shouldn't be communicating information via
5465 the global name buffer.
5466 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
5467 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

5487 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
5488 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
5489 Add String_To_Name with no side effects.

5493 * sem_ch3.adb (Analyze_Declarations): Add
5494 additional condition for edge case.

5498 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
5499 reserved words inside pragmas. This is necessary to allow the
5500 pragma name Interface to be used in pragma Ignore_Pragma.

6291 (Check_Dependency_Clause): Properly detect a match between two
6292 'Result attributes. Update the various post-match cases to use
6293 Is_Already_Matched as this routine now automatically recognizes
6294 a previously matched 'Result attribute.
6295 (Is_Already_Matched): New routine.
6296 (Remove_Extra_Clauses): New routine.
6297 (Report_Extra_Clauses): Remove the detection of ... => null

6302 * sem_aggr.adb (Resolve_Array_Aggregate): In ASIS mode do not
6303 report on spurious overlaps between values involving a subtype
6304 with a static predicate, because the expansion of such a subtype

6337 to the expected type with the appropriate check flags set.
6338 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
6339 base type if the range is null. It may still be invalid if it

6343 2017-01-23 Pierre-Marie de Rodat <derodat@adacore.com>
6345 * scos.ads: Introduce a constant to represent ignored

6356 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
6357 an object declaration for an array type with a modular index type
6358 with the size of Long_Long_Integer. Special processing is needed
6359 in this case to compute reliably the size of the object, and
6360 eventually to raise Storage_Error, when wrap-around arithmetic
6361 might compute a meangingless size for the object.
6363 2017-01-23 Justin Squirek <squirek@adacore.com>
6365 * a-wtenau.adb, par-endh.adb, sem_prag.adb,

6370 * sem_res.adb (Resolve_Call): In the part of the code where
6371 it is deciding whether to turn the call into an indexed
6372 component, avoid doing so if the call is to an instance of
6373 Unchecked_Conversion. Otherwise, the compiler turns it into an
6374 indexed component, and resolution of that turns it back into a
6375 function call, and so on, resulting in infinite recursion.
6376 * sem_util.adb (Needs_One_Actual): If the first formal has a
6377 default, then return False.
6379 2017-01-21 Eric Botcazou <ebotcazou@adacore.com>

6398 2017-01-20 Yannick Moy <moy@adacore.com>
6400 * sem_ch6.adb (Move_Pragmas): move some pragmas,

6422 2017-01-20 Ed Schonberg <schonberg@adacore.com>
6424 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
6425 must be treated as delayed aspect even if the expression is
6426 a literal, because the aspect affects the freezing and the
6427 elaboration of the object to which it applies.
6429 2017-01-20 Tristan Gingold <gingold@adacore.com>
6431 * s-osinte-vxworks.ads (Interrup_Range): New subtype.

6447 * exp_attr.adb (Constrained): Apply an access check (check that
6448 the prefix is not null) when the prefix denotes an object of an
6449 access type; that is, when there is an implicit dereference.
6451 2017-01-20 Gary Dismukes <dismukes@adacore.com>
6453 * s-rident.ads (constant Profile_Info): Remove

6467 * sem_ch8.adb (Analyze_Use_Package): Emit an error when a use
6468 package clause mentions Ghost and non-Ghost packages. Mark a
6469 use package clause as Ghost when it mentions a Ghost package.
6470 (Analyze_Use_Type): Emit an error when a use type clause mentions

6479 returns a limited view of a type and at the point of the call the
6480 function is not declared in the extended main unit then replace
6481 it with the non-limited view, which must be available. If the
6482 called function is in the extended main unit then no action is
6483 needed since the back-end handles this case.
6485 2017-01-20 Eric Botcazou <ebotcazou@adacore.com>
6487 * sem_ch7.adb (Contains_Subp_Or_Const_Refs): Rename into...

6493 incorrect shortcut for package declarations and bodies.
6495 2017-01-20 Ed Schonberg <schonberg@adacore.com>
6497 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
6498 base type differs from that of the completion and the private
6499 subtype is an itype (created for a constraint on an access
6500 type e.g.), set Delayed_Freeze on both to prevent out-of-scope
6503 2017-01-20 Hristian Kirtchev <kirtchev@adacore.com>
6505 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
6506 When inheriting the SPARK_Mode of a prior expression function,
6507 look at the properly resolved entity rather than the initial
6508 candidate which may denote a homonym.

7004 2017-01-13 Javier Miranda <miranda@adacore.com>
7006 * sem_ch6.adb (Cloned_Expression): New subprogram.
7007 (Freeze_Expr_Types): Complete previous patch since the expression
7008 of an expression-function may have iterators and loops with
7009 defining identifiers which, as part of the preanalysis of the
7010 expression, may be left decorated with itypes that will not be
7011 available in the tree passed to the backend.
7013 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7015 * checks.adb (Apply_Type_Conversion_Checks): Optimize a type
7016 conversion to Integer of an expression that is an attribute
7017 reference 'Pos on an enumeration type.
7019 2017-01-13 Bob Duff <duff@adacore.com>
7021 * atree.ads: Minor comment fix.
7023 2017-01-13 Justin Squirek <squirek@adacore.com>
7025 * sem_ch6.adb (Check_Aggregate_Accessibility): Ignore function
7026 calls in accessibility check on return statement.
7028 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
7030 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
7031 Ensure that the input body is a subprogram body before trying to
7032 determine whether it denoted an expression function. Note that
7033 subprogram body stubs cannot denote expression functions.
7035 2017-01-13 Gary Dismukes <dismukes@adacore.com>
7037 * bindgen.adb, sem_ch6.adb, binde.adb, exp_ch3.adb: Minor reformatting
7040 2017-01-13 Javier Miranda <miranda@adacore.com>
7042 * einfo.ads (Component_Bit_Offset): Fix documentation.
7043 * sem_ch13.adb (Check_Record_Representation_Clause): Skip check
7044 on record holes for components with unknown compile-time offsets.

7049 * g-locfil.ads: Minor comment fix.
7051 2017-01-13 Bob Duff <duff@adacore.com>
7053 * binde.adb (Elab_New): New elaboration order algorithm
7054 that is expected to cause fewer ABE issues. This is a work in
7055 progress. The new algorithm is currently disabled, and can be
7056 enable by the -dp switch, or by modifying the Do_Old and Do_New
7057 etc. flags and rebuilding. Experimental code is included to
7058 compare the results of the old and new algorithms.
7059 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
7060 can have multiple of these tables, so the old and new algorithms
7062 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
7063 parameter of type array. This avoids the global variable, and
7064 allows bounds checking (which is normally defeated by the tables
7065 packages). It also ensures that the Elab_Order is read-only
7067 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
7068 subprograms that need it, as above.
7069 * debug.adb: Document new -dp switch. Modify doc of old -do
7071 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
7072 and Bindgen. Move writing of closure (-R and -Ra switches)
7073 to Binde; that's more convenient.
7075 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7077 * sem_ch6.adb (Analyze_Expression_Function): If the expression
7078 function is a completion, all entities referenced in the
7079 expression are frozen. As a consequence, a reference to an
7080 uncompleted private type from an enclosing scope is illegal.
7082 2017-01-13 Javier Miranda <miranda@adacore.com>
7084 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
7085 (Analyze_Subprogram_Body_Helper): At the occurrence of an
7086 expression function declaration that is a completion, its
7087 expression causes freezing (AI12-0103).
7089 2017-01-13 Vadim Godunko <godunko@adacore.com>
7091 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and
7092 Reference functions of Ada.Containers.Indefinite_Holders.

7100 * exp_ch3.adb (Default_Initialize_Object): Do not default
7101 initialize an object when it is of a task type and restriction
7102 No_Tasking is in effect because the initialization is obsolete.
7103 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
7104 restriction No_Tasking is in effect.
7105 (Build_Master_Renaming): Do not rename a master when restriction
7106 No_Tasking is in effect.
7108 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7110 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
7111 the legality of An others clause applies as well to a choice in
7112 an Iterated_component_ association.
7113 (Resolve_Iterated_Component_Association): An others choice
7115 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
7116 Iterated_Component_Association is not static.
7118 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
7120 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
7121 control is passed to the expresion handler before the new mode

7124 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set
7125 in case control is passed to the expresion handler before the

7137 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7139 * sem_util.ads, sem_util.adb (Choice_List): Move function here
7140 from sem_aggr.adb, for use elsewhere.
7141 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
7142 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
7143 Iterated_Component_Present.
7144 * exp_aggr.adb: Use Choice_List throughout, to handle
7145 Iterated_Component_Associations.
7146 (Gen_Loop): Generate proper loop for an
7147 Iterated_Component_Association: loop variable has the identifier
7148 of the original association. Generate a loop even for a single
7149 component choice, in order to make loop parameter visible in
7151 (Flatten): An Iterated_Component_Association is not static.
7153 2017-01-13 Yannick Moy <moy@adacore.com>
7155 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
7156 float exponentiation for statically known small negative values
7157 is the reciprocal of the exponentiation for the opposite value
7159 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
7160 Ensure that the value of float exponentiation for negative values
7161 is the reciprocal of the exponentiation for the opposite value

7170 expression in delay statement as OK for volatile context.
7172 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7174 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
7175 mode a choice that is a subtype with a static predicate is
7176 replaced by the values it covers. This transformation must not
7177 be performed in ASIS mode, to preserve the source for analysis.
7179 2017-01-13 Justin Squirek <squirek@adacore.com>
7181 * nlists.ads: Correct minor typo.
7183 2017-01-13 Gary Dismukes <dismukes@adacore.com>

7190 Iterated_Component_Association is a named association in an
7192 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
7193 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
7194 and resolve the discrete choices and the expression of the
7196 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
7197 Loop_Actions and Box_Present are attributes of
7198 N_Iterated_Component_Association nodes. Box_Present is always
7200 * sprint.adb (Sprint_Node): An Iterated_Component_Association
7201 has a Discrete_Choices list, as specified in the RM. A
7202 Component_Association for aggregate uses instead a Choices list.
7203 We have to live with this small inconsistency because the new
7204 construct also has a defining identifier, and there is no way
7205 to merge the two node structures.
7207 2017-01-13 Yannick Moy <moy@adacore.com>
7209 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the

7216 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
7217 Analyze_Declarations, to analyze and resolve the expressions of
7218 aspect specifications in the current declarative list, so that
7219 the expressions have proper entity and type info. This is needed
7220 for ASIS when there is no subsequent expansion to generate this
7221 semantic information.
7222 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
7223 original expression, to suppress cascaded errors when expression
7224 has been constant-folded.
7225 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
7226 ASIS mode, because there is no subsequent expansion to decorate

7232 New function to detect when a call may be inlined or not in
7234 (Expand_Inlined_Call): Ensure that a temporary
7235 is always created in the cases where a type conversion may be
7236 needed on an input parameter in GNATprove mode, so that GNATprove
7237 sees the check to perform.
7238 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
7239 when not applicable due to actual requiring type conversion
7240 with possible check but no temporary value can be copied for
7241 GNATprove to see the check.
