24 * freeze.adb (Check_Component_Storage_Order): Default initialize
25 Comp_Byte_Aligned rather than silencing messages with pragma
26 Warnings(Off), which does not work for CodePeer initialization
27 messages, and given that here the possible read of an unitialized value
28 depends on a proper use of parameters by the caller.
29 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.
30 * sem_ch12.adb (Build_Operator_Wrapper): Default initialize Expr.

37 * sem_ch5.adb (Analyze_Assignment): Default initialize
39 * sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,
40 and restructure code to defend against previous errors, so that, in
41 that case, control does not flow to the elsif condition which read an
42 uninitialized Obj_Decl.
43 * sem_ch9.adb (Analyze_Requeue): Default initialize Synch_Type.
44 (Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
45 which seem to be left uninitialized and possibly read in some cases.
46 * sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more
47 precisely. This requires to exchange the test for exiting in case of
48 too many positions and the increment to Position, inside the loop.
49 * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,
50 which cannot be read uninitialized, but the reasons for that are quite

55 * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
56 and test for presence of non-null Opnd_Type before testing its scope,

92 2017-11-09 Bob Duff <duff@adacore.com>
94 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
95 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
96 objects can have those special values. Valid_Name_Id could usefully be
97 used all over the compiler front end, but that's too much trouble for
98 now. If we did that, we might want to rename:
99 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
100 For parameters of type Valid_Name_Id, remove some redundant tests,
101 including the ones found by CodePeer. Use Is_Valid_Name instead of
102 membership test when appropriate.
103 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
104 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
105 "in Error_Name_Or_No_Name".

1467 * freeze.ads: Minor comment fixed.
1469 2017-10-09 Bob Duff <duff@adacore.com>
1471 * exp_ch6.adb: (Make_Build_In_Place_Call_In_Object_Declaration): Take
1472 care of unchecked conversions in addition to regular conversions. This
1473 takes care of a case where a type is derived from a private untagged
1474 type that is completed by a tagged controlled type.
1476 2017-10-09 Ed Schonberg <schonberg@adacore.com>
1478 * exp_disp.adb (Build_Class_Wide_Check, Replace_Formals): When
1479 rewriting a class-wide condition, handle properly the case where the
1480 controlling argument of the operation to which the condition applies is
1481 an access to a tagged type, and the condition includes a dispatching
1482 call with an implicit dereference.

1493 * sem_ch4.adb (Try_Class_Wide_Operation, Traverse_Homonyms):
1494 Suppress spurious ambiguity error when two traversals of the homonym
1495 chain (first directly, and then through an examination of relevant
1496 interfaces) retrieve the same operation, when other irrelevant homonyms
1497 of the operatioh are also present.
1499 2017-10-09 Ed Schonberg <schonberg@adacore.com>
1501 * sem_util.adb (Object_Access_Level): If the object is the return
1502 statement of an expression function, return the level of the function.
1503 This is relevant when the object involves an implicit conversion
1504 between access types and the expression function is a completion, which
1505 forces the analysis of the expression before rewriting it as a body, so
1506 that freeze nodes can appear in the proper scope.
1508 2017-10-09 Bob Duff <duff@adacore.com>
1510 * atree.adb: Make nnd apply to everything "interesting", including
1511 Rewrite. Remove rrd.

1515 * exp_ch3.adb (Expand_N_Object_Declaration): Avoid never-ending loop
1516 processing the declaration of the dummy object internally created by
1517 Make_DT to compute the offset to the top of components referencing
1518 secondary dispatch tables.
1519 (Initialize_Tag): Do not initialize the offset-to-top field if it has
1520 been initialized initialized.
1521 * exp_disp.ads (Building_Static_Secondary_DT): New subprogram.
1522 * exp_disp.adb (Building_Static_Secondary_DT): New subprogram.
1523 (Make_DT): Create a dummy constant object if we can statically build
1524 secondary dispatch tables.
1525 (Make_Secondary_DT): For statically allocated secondary dispatch tables
1526 use the dummy object to compute the offset-to-top field value by means
1527 of the attribute 'Position.
1529 2017-10-09 Bob Duff <duff@adacore.com>
1531 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking
1532 code so if BIPAlloc is not passed in, it will likely raise
1533 Program_Error instead of cause miscellaneous chaos.
1534 (Is_Build_In_Place_Result_Type): Return False if not Expander_Active,
1535 as for the other Is_B-I-P... functions.
1536 * sem_aggr.adb (Resolve_Extension_Aggregate): For an extension
1537 aggregate whose ancestor part is a build-in-place call returning a
1538 nonlimited type, transform the assignment to the ancestor part to use a
1540 * sem_ch3.adb (Build_Itype_Reference): Handle the case where we're
1541 creating an Itype for a library unit entity.
1542 (Check_Initialization): Avoid spurious error message on
1543 internally-generated call.
1544 * sem_ch5.adb (Analyze_Assignment): Handle the case where the
1545 right-hand side is a build-in-place call. This didn't happen when b-i-p
1546 was only for limited types.
1547 * sem_ch6.adb (Create_Extra_Formals): Remove assumption that b-i-p
1548 implies >= Ada 2005.
1549 * sem_ch7.adb (Scan_Subprogram_Refs): Avoid traversing the same nodes
1551 * sem_util.adb (Next_Actual): Handle case of build-in-place call.

1576 * sem_ch12.adb (Analyze_Associations, Check_Generic_Parent): If an
1577 actual for a formal package is an instantiation of a child unit, create
1578 a freeze node for the instance of the parent if it appears in the same
1579 scope and is not frozen yet.
1581 2017-10-09 Pierre-Marie de Rodat <derodat@adacore.com>
1583 * exp_atag.ads, libgnat/a-tags.adb, libgnat/a-tags.ads: Enhance
1584 in-source documentation for tagged types's Offset_To_Top.
1586 2017-10-09 Bob Duff <duff@adacore.com>
1588 * exp_ch3.adb (Build_Assignment): Parameter name N was somewhat
1589 confusing. Same for N_Loc. Remove assumption that b-i-p implies
1590 limited. This is for the case of a function call that occurs as the
1591 default for a record component.
1592 (Expand_N_Object_Declaration): Deal with the case where expansion has
1593 created an object declaration initialized with something like
1595 * exp_ch3.adb: Minor reformatting.
1597 2017-10-09 Ed Schonberg <schonberg@adacore.com>
1599 * exp_attr.adb (Expand_Attribute_Reference, case 'Valid): The prefix of
1600 the attribute is an object, but it may appear within a conversion. The
1601 object itself must be retrieved when generating the range test that
1602 implements the validity check on a scalar type.
1604 2017-10-05 Eric Botcazou <ebotcazou@adacore.com>
1607 * mingw32.h (_O_U8TEXT, _O_U16TEXT, _O_WTEXT): Delete.

1621 * gcc-interface/decl.c (annotate_value): Use wi::to_widest when
1622 handling the form (plus/mult (convert @0) @1).
1624 2017-09-29 Bob Duff <duff@adacore.com>
1626 * exp_ch6.adb (Expand_Call_Helper): Replace with code more similar to
1628 (Make_Build_In_Place_Call_In_Object_Declaration): Back out previous
1629 change. Set the Etype in the class-wide case. This fixes a regression
1630 in the libadalang test suite.
1632 2017-09-29 Joel Brobecker <brobecker@adacore.com>
1634 * doc/gnat_ugn/building_executable_programs_with_gnat.rst,

1655 * exp_ch6.adb (Expand_Call_Helper): Handle case of build-in-place
1656 functions returning nonlimited types. Allow for qualified expressions
1657 and type conversions.
1658 (Expand_N_Extended_Return_Statement): Correct the computation of
1659 Func_Bod to allow for child units.
1660 (Expand_Simple_Function_Return): Remove assumption that b-i-p implies
1661 limited (initialization of In_Place_Expansion), and implies >= Ada
1663 (Is_Build_In_Place_Result_Type): New function to accompany
1664 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
1665 sometimes we just have the type on our hands, not the function. For
1666 now, does the same thing as the old version, so build-in-place is
1667 disabled for nonlimited types, except that you can use -gnatd.9 to
1669 * exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
1670 accompany Is_Build_In_Place_Function and
1671 Is_Build_In_Place_Function_Call, because sometimes we just have the
1672 type on our hands, not the function.
1673 (Make_Build_In_Place_Call_In_...): Handle nonlimited build-in-place
1675 (Make_Build_In_Place_Call_In_Object_Declaration): Remove the
1676 questionable code at the end that was setting the Etype.
1677 * exp_aggr.adb (Is_Build_In_Place_Aggregate_Return): New function to
1678 determine whether "return (...agg...);" is returning from a
1679 build-in-place function.

1681 Remove assumption that b-i-p implies limited (initialization of
1682 In_Place_Expansion).
1683 (Build_Record_Aggr_Code): AI-287: fix comment; it can't be wrapped in
1684 an unchecked conversion. Add assertions.
1685 (Convert_Aggr_In_Object_Decl): Establish_Transient_Scope -- no need for
1686 secondary stack here, just because the type needs finalization. That

1708 b-i-p implies >= Ada 2005.
1709 * exp_util.adb (Build_Allocate_Deallocate_Proc): Look at Storage_Pool
1710 (Expr), in case Pool_Id is not set.
1711 (Initialized_By_Aliased_BIP_Func_Call): Handle case where the call is
1712 qualified or converted.
1713 (Is_Secondary_Stack_BIP_Func_Call): Don't check if Nkind (Selector_Name
1714 (Param)) = N_Identifier; that's all it could be.
1715 * sinfo.ads: Comment fixes.
1716 * snames.ads-tmpl: Comment fixes.

1749 * sem_ch6.adb (Analyze_Expression_Function): Do not emit freeze nodes
1750 for types in expression if the function is within a generic unit.
1751 * sem_res.adb (Resolve): In a generic context do not freeze an
1752 expression, unless it is an entity. This exception is solely for the
1753 purpose of detecting illegal uses of deferred constants in generic

1825 given set is highest in scope (not always the most prev).
1826 (Use_One_Package, Use_One_Type): Major cleanup and reorganization to
1827 handle the new chaining algorithm, also many changes related to
1828 redundant clauses. A new parameter has also been added to force
1829 installation to handle certain cases.

1856 (rather than relocating it) to avoid resolving a potentially malformed
1857 tree when the expression is resolved through an ASIS-specific call to

2699 2017-09-08 Yannick Moy <moy@adacore.com>
2701 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
2702 return the entity associated with the call.
2703 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
2704 Replace the internal Get_Function_Id with the new
2705 Sem_Aux.Get_Called_Entity.
2706 (Iterate_Call_Parameters): New
2707 procedure to iterate on formals and actuals at the same time.
2708 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
2709 Set SPARK_Mode from spec when set, for analysis
2710 of instance. Restore after analysis of instance.
2711 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
2712 set, for analysis of body instance. Restored automatically at
2713 the end of the subprogram.
2714 * gnat1drv.adb (Adjust_Global_Switches): Set
2715 Check_Validity_Of_Parameters to False in GNATprove mode.
2716 * opt.ads (Check_Validity_Of_Parameters): Document switch to
2719 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
2721 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
2722 (New_Copy_Tree): ...there. Reset the hash tables only if they
2723 were used in the previous invocation.
2724 * s-htable.adb: Fix typo.
2726 2017-09-08 Bob Duff <duff@adacore.com>
2728 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
2730 2017-09-08 Arnaud Charlet <charlet@adacore.com>
2732 * sem_aggr.adb: minor style fix.
2734 2017-09-08 Bob Duff <duff@adacore.com>
2736 * sprint.adb (Write_Corresponding_Source): Ignore if there is
2737 no current source file.
2738 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
2739 Print something helpful in case N is invalid.
2740 * sprint.ads: Minor comment fix.
2742 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
2744 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
2747 2017-09-08 Bob Duff <duff@adacore.com>
2749 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
2750 Ada_2020, along the same lines as the other Ada version pragmas.
2752 2017-09-08 Gary Dismukes <dismukes@adacore.com>
2754 * sem_ch12.adb: Minor typo fixes and reformatting.
2756 2017-09-08 Yannick Moy <moy@adacore.com>
2758 * sem_aggr.adb (Resolve_Record_Aggregate):
2759 Rewrite bounds of aggregate subexpressions which may depend on
2760 discriminants of the enclosing aggregate.
2762 2017-09-08 Yannick Moy <moy@adacore.com>
2764 * sem_ch5.adb: Prevent assertion failure on illegal code.
2766 2017-09-08 Yannick Moy <moy@adacore.com>
2768 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
2769 calling Renamed_Entity on an entity which cannot be a renaming.
2771 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
2773 * exp_aggr.adb: Add with & use clause for Urealp.
2774 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
2775 elementary types instead of just discrete types.
2776 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
2777 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
2778 Be prepared for the FP zero value in the memset case. Add small
2781 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
2783 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
2786 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
2788 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
2789 of New_Copy because the latter leaves the syntactic structure of
2790 the tree inconsistent (a child is accessible through two parents)
2791 and prevents proper replication of itypes by subsequent calls
2793 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
2794 New_Copy because the latter leaves the syntactic structure of the
2795 tree inconsistent (a child is accessible through two parents)
2796 and prevents proper replication of itypes by subsequent calls
2798 * sem_util.adb (In_Subtree): New routine.

2805 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
2806 for aspect Default_Value is a static scalar value, but it does
2807 not freeze the type. Yhis allows for subsequent representation
2808 clauses for the type.
2810 2017-09-08 Javier Miranda <miranda@adacore.com>
2812 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
2813 not add entries into the undefined reference table when we are
2814 compiling with errors ignored.
2816 2017-09-08 Ed Schonberg <schonberg@adacore.com>
2818 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
2819 check if the instance is within an enclosing instance body. The
2820 formal package was legal in the enclosing generic, and is
2821 legal in the enclosing instantiation. This optimisation may be
2822 applicable elsewhere, and it also removes spurious errors that
2823 may arise with on-the-fly processing of instantiations that
2824 contain Inline_Always subprograms.
2826 2017-09-08 Vincent Celier <celier@adacore.com>
2828 * gnatcmd.adb: Disregard empty argument of GNAT driver.
2830 2017-09-08 Justin Squirek <squirek@adacore.com>
2832 * checks.adb (Insert_Valid_Check): Manually decorate
2833 the generated temporary for range valdity checks.
2835 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
2837 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
2839 2017-09-08 Justin Squirek <squirek@adacore.com>
2841 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
2842 case to handle underscore flags.
2843 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
2844 new procedure to handle underscores.
2846 2017-09-08 Javier Miranda <miranda@adacore.com>
2848 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
2849 divisions with fixed point results to avoid generating twice
2850 the runtime check on divide by zero.
2851 * checks.adb (Apply_Divide_Checks): Ensure that operands are
2852 not evaluated twice (once for their runtime checks and once for
2853 their regular computation).
2855 2017-09-08 Yannick Moy <moy@adacore.com>
2857 * sem_prag.adb (Analyze_Part_Of): Add missing
2858 return statements after issuing errors. Add detection of
2859 out-of-order item and single concurrent type.

2966 New routine to read the Tag robustly.
2967 * exp_attr.adb (Input): Change the expansion of 'Input,
2968 in the class-wide case, to call String_Input_Tag instead of
2969 String_Input_Blk_IO.
2971 2017-09-08 Arnaud Charlet <charlet@adacore.com>
2973 * s-rident.ads (Restriction_Id): reorder enum
2974 literals, so that Pure_Barriers is no longer in range of the
2975 Cunit_Boolean_Restrictions subtype.
2977 2017-09-08 Nicolas Roche <roche@adacore.com>
2979 * a-taster.ads, a-taster.adb: Move to libgnarl

2989 when the actual is a construct that involves a dereference of an
2990 expression that includes a formal of the enclosing subprogram,
2991 In such cases, the accessibility level of the actual is that of
2992 the corresponding formal, which is passed in as an additional
2993 actual in the outer call.
2995 2017-09-08 Bob Duff <duff@adacore.com>

3000 2017-09-08 Bob Duff <duff@adacore.com>
3002 * a-tags.adb (Internal_Tag): Unsuppress checks, so we get
3003 exceptions instead of crashes. Check for absurdly long strings
3004 and empty strings. Empty strings cause trouble because they can
3005 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
3006 be empty, which causes an array index out of bounds.
3007 * s-ststop.adb (Input): Unsuppress checks, so we get exceptions
3010 2017-09-08 Arnaud Charlet <charlet@adacore.com>

3189 all the types that are referenced by the expression.
3190 (Analyze_Expression_Function): Call Freeze_Expr_Types for
3191 a completion instead of manually freezing the type of the

3195 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3197 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
3198 New procedure, auxiliary to Expand_Pragma_Check, to handle
3199 references to the discriminants of a protected type within a
3200 precondition of a protected operation. This is needed because
3201 the original precondition has been analyzed in the context of
3202 the protected declaration, but in the body of the operation
3203 references to the discriminants have been replaved by references
3204 to the discriminants of the target object, and these references
3205 are only created when expanding the protected body.
3207 2017-09-08 Yannick Moy <moy@adacore.com>
3209 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
3212 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3214 * exp_attr.adb (Build_Record_VS_Func): If the record is an
3215 unchecked union, do not emit checks for its (non-existent)
3216 discriminants, or for variant parts that depend on them.
3218 2017-09-08 Justin Squirek <squirek@adacore.com>
3220 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
3221 Find_Comparison_Type.Try_One_Interp): Add check for generic

3226 * sem_ch3.adb, layout.adb, layout.ads, exp_attr.adb, debug.adb,
3227 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
3228 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,

3230 remaining references to AAMP_On_Target.
3232 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3234 * style.adb: Fix typo.
3236 2017-09-08 Javier Miranda <miranda@adacore.com>
3238 * einfo.adb (Underlying_Type): Add missing support for class-wide
3239 types that come from the limited view.

3241 interfaces using the underlying type to handle limited-withed
3243 (Attribute_Tag): Check class-wide type interfaces using
3244 the underlying type to handle limited-withed types.
3246 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3248 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
3249 over a subtype of a type with a static predicate, taking into
3250 account the predicate function of the parent type and the bounds
3251 given in the loop specification.
3252 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
3253 a loop specification that is a subtype indication whose type mark
3254 is a type with a static predicate, inherit predicate function,
3255 used to build case statement for rewritten loop.
3257 2017-09-08 Justin Squirek <squirek@adacore.com>
3259 * lib-load.adb: Modify printing of error message to exclude file
3262 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3264 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
3265 don't inline subprograms declared in both visible and private
3267 (In_Package_Spec): previously In_Package_Visible_Spec; now
3268 detects subprograms declared both in visible and private parts
3271 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3273 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
3274 the type is an anonymous array in an object declaration, whose
3275 component type has an invariant, use the object declaration
3276 as the insertion point for the invariant procedure, given that
3277 there is no explicit type declaration for an anonymous array type.
3279 2017-09-08 Bob Duff <duff@adacore.com>
3281 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.

3296 Default_WCEM by default (i.e. if the encoding is not specified
3297 by the Form string).
3299 2017-09-08 Bob Duff <duff@adacore.com>
3301 * s-trasym.ads (Hexa_Traceback): If
3302 Suppress_Hex is True, print "..." instead of a hexadecimal
3304 * s-trasym.adb: Ignore No_Hex in this version.
3307 2017-09-08 Bob Duff <duff@adacore.com>
3309 * debug.adb: Minor reformatting.
3311 2017-09-08 Bob Duff <duff@adacore.com>
3313 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
3314 code so it doesn't trigger an "uninit var" warning.
3316 2017-09-08 Nicolas Roche <roche@adacore.com>
3318 * s-hibaen.ads: Remove obsolete file.
3320 2017-09-08 Arnaud Charlet <charlet@adacore.com>

3337 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3339 * debug.adb (dA): Adjust comment.
3340 * gnat1drv.adb (Gnat1drv): Likewise.
3341 * opt.ads (List_Representation_Info_Extended): New variable.
3342 * repinfo.adb (List_Record_Info): Split implementation into...
3343 (Compute_Max_Length): ...this. Recurse on records if requested.
3344 (List_Record_Layout): Likewise.
3345 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
3346 statement, accept '0' and set List_Representation_Info_Extended
3348 * usage.adb (Usage): Document new -gnatRe variant.
3350 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3352 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
3353 Do not save the given entity in the global variable Default_Pool
3354 if the pragma appears within a generic unit.
3356 2017-09-08 Bob Duff <duff@adacore.com>
3358 * errout.adb (Delete_Warning): Do not
3359 decrement Warnings_Treated_As_Errors. This is called before
3360 Warnings_Treated_As_Errors has been incremented to account for
3361 this warning. Decrementing it here can lead to negative values
3362 of Warnings_Treated_As_Errors, raising Constraint_Error in
3363 checks-on builds, and causing the compiler to return an error
3364 code in checks-off builds.
3366 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3368 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
3369 entities of named concurrent types as Ref_Id and not of anonymous
3370 concurrent objects (because callers already know when a conversion
3371 is necessary and can easily do it); also, do not expect protected
3372 types or protected objects as Context_Id (because no flow-related
3373 SPARK pragmas are attached there); reflect these changes in a
3374 more precise comment.
3376 2017-09-08 Olivier Hainque <hainque@adacore.com>
3378 * g-altive.ads: Add documentation.
3380 2017-09-08 Bob Duff <duff@adacore.com>
3382 * sem_util.ads, debug.adb: Minor comment fix.
3383 * erroutc.ads: Comment fix.
3385 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3387 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
3388 for compatibility of component types of formal and actual in an
3389 instantiation of a child unit, when the component type of the
3390 formal is itself a formal of an enclosing generic.
3392 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3394 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
3395 sem_prag.adb to make it available for GNATprove; for concurrent
3396 types replace custom scope climbing with Scope_Same_Or_Within; for
3397 single concurrent objects add scope climbing (with Scope_Within),
3398 which was not there (that's the primary semantic change of this
3399 commit); also, when comparing a single concurrent object with
3400 its corresponding concurrent type rely on equality of types,
3401 not of objects (because that's simpler to code).
3402 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
3403 (Analyze_Global_Item): adjust special-casing of references to the
3404 current instance of a concurrent unit in the Global contracts
3405 of task types and single tasks objects; similar for references
3406 in the protected operations and entries of protected types and
3407 single protected objects (in all these cases the current instance
3408 behaves as an implicit parameter and must not be mentioned in
3409 the Global contract).

3949 Add missing implicit type conversion to force displacement of the
3952 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
3954 * sem_ch3.adb, sem_aux.adb, sem_res.adb: Minor reformatting.
3956 2017-09-06 Yannick Moy <moy@adacore.com>
3958 * sem_ch12.adb (Analyze_Instance_And_Renamings): Refactor to set
3959 global variable Ignore_SPARK_Mode_Pragmas_In_Instance only once.
3961 2017-09-06 Bob Duff <duff@adacore.com>
3963 * sem_ch8.adb: Change Assert to be consistent with
3966 2017-09-06 Bob Duff <duff@adacore.com>
3968 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
3969 requested. Previously, the -do switch meant "run Elab_New and
3970 Elab_Old and use the order chosen by Elab_Old, possibly with
3971 debugging printouts comparing the two orders." Now it means
3972 "do not run Elab_New." This is of use if there are bugs that
3973 cause Elab_New to crash.
3974 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
3976 * ali.ads (Elab_Position): Change type to Nat, to avoid various
3979 2017-09-06 Arnaud Charlet <charlet@adacore.com>
3981 * sem_prag.adb (Check_Mode_Restriction_In_Enclosing_Context): Fix
3982 reference to SPARK RM.
3984 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
3986 * layout.adb: Use SSU short hand consistently throughout the file.
3988 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
3990 * freeze.adb (Freeze_Record_Type)
3991 <Sized_Component_Total_Round_RM_Size>: New local variable to
3992 accumulate the rounded RM_Size of components. Update it for
3993 every component whose RM_Size is statically known. Add missing
3994 guard to check that bit packing is really required before issuing
3995 the error about packing. Swap condition for clarity's sake.
3996 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.

4015 project manager sources.
4017 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4019 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
4020 entity of a mutable type and the right-hand side is a conditional
4021 expression, resolve the alternatives of the conditional using
4022 the base type of the target entity, because the alternatives
4023 may have distinct subtypes. This is particularly relevant if
4024 the alternatives are aggregates.
4026 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4028 * checks.adb (Apply_Predicate_Check): If the expression is an
4029 aggregate that is the RHS of an assignment, apply the check to
4030 the LHS after the assignment, rather than to the aggregate. This
4031 is more efficient than creating a temporary for the aggregate,
4032 and prevents back-end crashes when the aggregate includes a
4033 dynamic "others' association.
4035 2017-09-06 Yannick Moy <moy@adacore.com>
4037 * sem_ch12.adb (Analyze_Instance_And_Renamings):

4039 of the generated package declaration.
4041 2017-09-06 Yannick Moy <moy@adacore.com>
4043 * sem_res.adb (Resolve_Call): Do not issue a
4044 message for calls inside expression function, unless body was
4045 seen and is candidate for inlining.
4047 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4049 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.
4050 * sem_ch3.adb (Analyze_Declarations): In a generic subprogram
4051 body. do not freeze the formals of the generic unit.
4053 2017-09-06 Gary Dismukes <dismukes@adacore.com>
4055 * errout.adb (Error_Msg): Separate the
4056 treatment for warning vs. style messages in inlinings and
4057 instantiations. Prevents blowups on calls to Warn_Insertion for
4058 style messages, which should not be called in that case because
4059 Warning_Msg_Char is not set.
4061 2017-09-06 Justin Squirek <squirek@adacore.com>
4063 * sem_prag.adb (Check_VFA_Conflicts): Created
4064 to group all Volatile_Full_Access checks relating to other
4065 representation pragmas (Mark_Component_Or_Object): Created
4066 to centeralize the flagging of attributes for the record type
4067 component case, a pragma applied individually to a component, and
4069 (Process_Atomic_Independent_Shared_Volatile):
4070 Add propagation of certain pragmas to record components and move
4071 evaluation of VFA checks
4073 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4075 * sem_prag.adb (Check_Postcondition_Use_In_Inlined_Subprogram):

4084 2017-09-06 Bob Duff <duff@adacore.com>
4086 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
4087 that is a proper body corresponding to a stub, we defer the
4088 adjustment of the sloc until after the correct adjustment has
4089 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
4090 the adjustment, because it will be outside the range in (the old,
4091 incorrect) S_Adjustment.
4092 * inline.adb: Use named notation for readability and uniformity.
4093 * sinput-l.adb: Minor improvements to debugging output printed
4095 * sinput-l.ads (Create_Instantiation_Source): Minor comment
4098 2017-09-06 Vincent Celier <celier@adacore.com>

4104 * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a

4108 * make.adb: Minor reformatting
4110 2017-09-06 Justin Squirek <squirek@adacore.com>
4112 * einfo.adb (Set_Linker_Section_Pragma): Modify
4113 Set_Linker_Section_Pragma to be consistant with the "getter"
4114 Linker_Section_Pragma.
4115 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
4116 checking for container loops so that the index cursor is not
4117 directly changable by the user with the use of E_Loop_Parameter.
4118 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.

4160 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4162 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
4163 Generate a freeze node for the actual of a formal package, if
4164 the actual is declared in the same unit and has a corresponding
4165 body, to prevent the current instance from being frozen before
4168 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>

4190 missing case of controlled generalized indexing.
4191 (Is_Source_Object): Use routine Strip to remove indirections.
4192 (Strip): New routine.
4194 2017-09-06 Bob Duff <duff@adacore.com>
4196 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
4197 we include the proper header. Otherwise, we just declare the necessary
4198 things from the capabilities library. This is so we can build on
4199 machines without that library, while still enabling that library.
4200 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
4201 simply return 0 if the library is not present, or not included

4206 * exp_dbug.adb (Debug_Renaming_Declaration): Do not create an encoding

4217 has no parameter specification and no entry index, use the entry name
4218 as the end of the generated SCO statement.
4220 2017-09-06 Steve Baird <baird@adacore.com>
4222 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
4223 uses of 'Image and related attributes as having side effects in
4224 order to avoid replicating such uses.
4225 * pprint.ads (Expression_Image) Add new generic formal flag
4226 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
4227 (eventually) override the default.
4228 * pprint.adb (Expression_Image) If the new flag is set, then
4229 suppress the ".all" suffix when displaying a dereference whose
4230 prefix is a use of a value-capturing compiler temp of the sort
4231 generated by Expr_Util.Remove_Side_Effects .
4232 * exp_attr.adb, g-catiio.adb, inline.adb, sem_attr.adb, sem_ch13.adb,

4245 * sem_util.adb, sem_util.ads (Within_Protected_Type): Renaming
4246 with slight modification from Is_Subp_Or_Entry_Inside_Protected,
4247 so that applies to any entity.
4249 2017-09-06 Yannick Moy <moy@adacore.com>
4251 * sem_ch3.adb (Derived_Type_Declaration): Use
4252 Incomplete_Or_Partial_View rather than local Find_Partial_View.
4254 2017-09-06 Javier Miranda <miranda@adacore.com>
4256 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
4259 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4261 * sem_dim.adb (Analyze_Dimension): In an instance, a type
4262 conversion takes its dimensions from the expression, not from
4264 (Dimensions_Of_Operand): Ditto.
4266 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4268 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to
4269 null procedures when GNAT coverage is used, so that their (empty)
4270 bodies are properly covered.
4272 2017-09-06 Bob Duff <duff@adacore.com>
4274 * sem_ch13.adb (Resolve_Aspect_Expressions): If
4275 the entity is a type with discriminants, make the discriminants
4276 directly visible in aspect clauses.
4278 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4280 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are
4281 Universal_Real and the context is a floating-point type, resolve
4282 both operands to the target type.

4289 2017-09-06 Yannick Moy <moy@adacore.com>
4291 * freeze.adb (Check_Inherited_Conditions): Rewriting
4292 of inherited preconditions and postconditions should only occur
4293 in GNATprove mode, that is, when GNATprove_Mode is True, not to
4294 be confused with SPARK_Mode being On.
4296 2017-09-06 Yannick Moy <moy@adacore.com>

4309 on the procedure created to encapsulate the body.
4310 * sem_ch7.adb: Add with clause for GNAT.HTable.
4311 (Entity_Table_Size): New constant.
4312 (Entity_Hash): New function.
4313 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
4314 (Is_Subprogram_Ref): Rename into...
4315 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
4316 the table instead of bailing out on them. Scan the value of constants
4317 if it is not known at compile time.
4318 (Contains_Subprograms_Refs): Rename into...
4319 (Scan_Subprogram_Refs): ...this.
4320 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
4321 Is_Public flag on subprograms if they are not actually referenced.
4322 (Hide_Public_Entities): Beef up comment on the algorithm.
4323 Reset the table of subprograms on entry.
4325 2017-09-06 Yannick Moy <moy@adacore.com>

4366 of protected subprograms and entries.
4367 * sem_util.adb, sem_util.ads (Is_Subp_Or_Entry_Inside_Protected):
4368 New function to detect when a subprogram of entry is defined
4369 inside a protected object.

4375 * s-taprop-linux.adb (Get_Ceiling_Support): Update this to allow
4376 ceiling priorities if the current process has the CAP_SYS_NICE
4379 2017-09-06 Bob Duff <duff@adacore.com>
4381 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint
4382 check back to the body, because SPARK is not yet ready for
4383 "or else raise Constraint_Error".
4385 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4387 * exp_ch6.adb (Expand_Call_Helper): Replace call to null

4405 * gnatcmd.adb: gnat ls -V -P... invokes gprls -V -P... The code
4406 from the Prj hierarchy has been removed from the GNAT driver.
4408 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4410 * sem_type.adb (Interface_Present_In_Ancestor): Within an
4411 expression function, or within a spec expression (default value,
4412 etc) a reference to an incomplete type is legal: legality of
4413 the operation will be checked when some related entity (type,
4414 object or subprogram) is frozen.
4416 2017-09-06 Gary Dismukes <dismukes@adacore.com>
4418 * exp_ch5.adb, s-diinio.ads, sem_ch4.adb, s-diflio.ads: Minor spelling

4429 * a-comlin.ads, a-comlin.adb (Argument): Simplify the code, now that
4430 we can use modern Ada in this package.
4431 * s-resfil.ads, s-resfil.adb, a-clrefi.ads, a-clrefi.adb:
4432 Move Ada.Command_Line.Response_File to System.Response_File,
4433 and make Ada.Command_Line.Response_File into a rename of
4434 System.Response_File. This is to avoid having gnatbind depend
4435 Ada.Command_Line, which would damage the bootstrap process now
4436 that Ada.Command_Line contains modern Ada (the raise expression).
4437 * gnatbind.adb: Avoid dependence on
4438 Ada.Command_Line. Depend on System.Response_File instead
4439 of Ada.Command_Line.Response_File. Change one call to
4440 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
4441 to Ada.Command_Line.Argument_Count to use Arg_Count.
4442 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
4444 2017-09-06 Bob Duff <duff@adacore.com>
4446 * frontend.adb (Frontend): Skip -gnatec=gnat.adc

4451 * exp_ch5.adb (Get_Default_Iterator): Replace
4452 "Assert(False)" with "return Iter", because if an iterable

4510 rule in 6.5.1 (7/2): if a renaming is a completion of a subprogram
4511 with No_Return, the renamed entity must be No_Return as well.
4513 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
4515 * exp_ch5.adb, freeze.adb, exp_ch4.adb, exp_ch6.adb, lib-xref.adb:

4532 * freeze.adb (Freeze_Entity): Do not generate a freeze
4533 node for a generic unit, even if it includes delayed aspect

4577 of the right-hand side has stored constraint, use its values
4578 (except for those that are renamings of parent discriminants)
4579 to produce additional assignments for the discriminants of the
4580 left-hand side, which are invisible in the righ-hand side and
4581 not retrievable as selected components.
4583 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4585 * sem_util.adb (Needs_One_Formal): The first formal of such a

4605 * sem_ch12.adb (Analyze_Subprogram_Instantiation): Propagate
4606 No_Return flag to instance if pragma applies to generic unit. This
4607 must be done explicitly because the pragma does not appear
4608 directly in the generic declaration (unlike the corresponding
4609 aspect specification).

4620 * exp_ch4.adb (Handle_Changed_Representation): For an untagged
4621 derived type with a mixture of renamed and constrained parent
4622 discriminants, the constraint for the target must obtain the
4623 discriminant values from both the operand and from the stored
4624 constraint for it, given that the constrained discriminants are
4625 not visible in the object.
4626 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
4627 side may be derived from that of the left-hand side (as in the
4628 case of an assignment with a change of representation) so the
4629 discriminant to be used in the retrieval of the value of the
4630 component must be the entity in the type of the right-hand side.
4632 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>

4659 in a set membership is an overloaded enumeration literal, and
4660 the type of the alternative is resolved from a previous one,
4661 replace the entity of the alternative as well as the type,
4662 to prevent inconsistencies between the entity and the type.

5205 * exp_ch6.adb (Expand_Call_Helper): When locating the
5206 accessibility entity created for an access parameter, handle
5207 properly a reference to a formal of an enclosing subprogram. if
5208 the reference appears in an inherited class-wide condition, it
5209 is the rewriting of the reference in the ancestor expression,
5210 but the accessibility entity must be that of the current formal.
5212 2017-05-02 Javier Miranda <miranda@adacore.com>
5214 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

5249 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
5250 procedure body for a local (sub)type declaration within a
5251 predicate function. Invariant checks do not apply to these, and
5252 the expansion of the procedure will happen in the wrong scope,
5253 leading to misplaced freeze nodes.
5255 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5257 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
5258 to analyze generated actions. If the main unit is a body,

5263 * einfo.adb (Declaration_Node): flip branches of

5294 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
5295 Refine predicate for the case where the primitive operation
5296 is a renaming of equality. An overriding operation that is
5297 a user-defined renaming of predefined equality inherits its
5298 slot from the overridden operation. Otherwise it is treated
5299 as a predefined op and occupies the same predefined slot as
5300 equality. A call to it is transformed into a call to its alias,
5301 which is the predefined equality. A dispatching call thus uses
5302 the proper slot if operation is further inherited and called
5303 with class-wide arguments.
5305 2017-05-02 Justin Squirek <squirek@adacore.com>
5307 * errout.adb (Set_Msg_Text): Add a case to switch the message

5340 * exp_ch3.adb (Build_Initialization_Call): Generate a null
5341 statement if the initialization call is a null procedure, as
5342 can happen with a controlled type with no explicit Initialize
5343 procedure, or an array of such.
5344 * exp_ch7.adb (Process_Object_Declaration): For a type with
5345 controlled components that has a trivial Initialize procedure,
5346 insert declaration for finalization counter after object

5349 finalization block and attendant declarations if component has
5350 a trivial Initialize procedure.

5352 a trivial Initialize procedure.

5382 2017-05-02 Gary Dismukes <dismukes@adacore.com>
5384 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
5385 parameter Array_Comp to indicate the case of an array object
5386 with null-excluding components.
5387 * checks.adb (Null_Exclusion_Static_Checks):
5388 Call Compile_Time_Constraint_Error instead of
5389 Apply_Compile_Time_Constraint_Error in the component case. Also
5390 call that when Array_Comp is True, with an appropriate warning for
5391 the array component case. Only create an explicit initialization
5392 by null in the case of an object of a null-excluding access type
5393 (and no longer do that in the component case).
5394 * sem_ch3.adb (Check_Component): Add a Boolean parameter
5395 Array_Comp defaulted to False. Pass Empty for the Comp
5396 actual when calling Null_Exclusion_Static_Checks in the case
5397 where Comp_Decl matches Object_Decl, because we don't have a
5398 component in that case. In the case of an object or component
5399 of an array type, pass True for Array_Comp on the recursive call

5404 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
5405 compute the linux priority from the Ada priority. Call this everywhere
5406 required. In particular, the previous version was not doing this
5407 computation when setting the ceiling priority in various places. It
5408 was just converting to C.int, which results in a ceiling that is off
5411 2017-05-02 Ed Schonberg <schonberg@adacore.com>

5430 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
5431 here from exp_ch9, to recognize objects whose creation requires
5432 dynamic allocation, so that the proper warning can be emitted
5433 when restriction No_Implicit_Heap_Allocation is in effect.
5434 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
5435 to emit proper warning when an object that requires dynamic
5436 allocation is declared.

5440 * s-trasym.ads, s-trasym.adb (Enable_Cache): New.
5442 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5444 * sem_ch4.adb (Find_Equality_Types, Try_One_Interp): The same relaxed
5445 visibility rules for equality operators that apply within an
5446 instantiation apply within an inlined body.
5447 * sem_type.adb (Add_One_Interp): ditto.
5449 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>

5457 (Name_Assume, Name_Attribute_Definition, Name_Loop_Optimize,
5458 Name_No_Tagged_Streams): Move to regular pragmas. Add
5459 placeholders for Default_Scalar_Storage_Order, Dispatching_Domain,
5460 and Secondary_Stack_Size.

5462 Pragma_Attribute_Definition, Pragma_Loop_Optimize and
5463 Pragma_No_Tagged_Streams to second part.

5483 * checks.adb (Apply_Constraint_Check): Do not apply
5484 a discriminant check when the associated type is a constrained
5485 subtype created for an unconstrained nominal type.
5486 * exp_attr.adb: Minor reformatting.
5488 2017-05-02 Bob Duff <duff@adacore.com>

5500 operator /= into negation of operator = when needed.
5501 (Expand_SPARK): Call new
5502 function to expand operator /=.
5504 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5506 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
5507 Simplify the expression for a fixed-fixed division to remove
5508 divisions by constants whenever possible, as an optimization
5509 for restricted targets.
5511 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
5513 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
5515 2017-05-02 Bob Duff <duff@adacore.com>
5517 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
5518 to find primitive ops, instead of using an Identifier that will
5519 later be looked up. This is necessary because these ops are not
5520 necessarily visible at all places where we need to call them.
5521 * exp_util.ads: Minor comment fix.
5523 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5525 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
5526 references are fully conformant if they are both expansions
5527 of the discriminant of a protected type, within one of the
5528 protected operations. One occurrence may be expanded into a
5529 constant declaration while the other is an input parameter to
5530 the corresponding generated subprogram.

5534 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
5535 recursivly searching composite-types for null-excluding access
5536 types and verifying them.
5537 (Analyze_Object_Declaration): Add a
5538 call to Check_Null_Excluding_Components for static verification
5539 of non-initialized objects.
5540 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
5541 a parameter for a composite-type's component and an extra case
5542 for printing component information.

5546 * sem_ch10.adb (Analyze_Subunit): Take
5547 configuration pragma into account when restoring appropriate
5548 pragma for analysis of subunit.
5550 2017-05-02 Justin Squirek <squirek@adacore.com>

5553 s-mudido-affinity.adb,, a-exetim-posix.adb, a-direio.adb,
5554 g-socket.adb, s-taenca.adb, s-fileio.adb: Remove unused use-type
5555 clauses from the runtime.
5557 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
5559 * freeze.adb (Check_Component_Storage_Order): Do not treat bit-packed
5560 array components specially.
5562 2017-05-02 Ed Schonberg <schonberg@adacore.com>
5564 * sem_ch8.adb (Premature_Usage): If the premature usage of
5565 an entity is as the expression in its own object decaration,
5566 rewrite the reference as Any_Id to prevent cascaded errors or
5567 compiler loops when such an entity is used in an address clause.
5569 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
5571 * gcc-interface/decl.c (components_to_record): Add missing guard.

5576 Put back pending fields onto the regular list if the misalignment
5577 happens to cancel itself.
5579 2017-04-28 Ed Schonberg <schonberg@adacore.com>
5581 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
5582 controlling actual in a prefixed call, preserve the original node
5583 information if the prefix itself has been rewritten, for ASIS use.
5585 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
5587 * exp_ch6.adb (Insert_Post_Call_Actions):
5588 Code clean up. Insert the post-call actions after an enclosing
5589 procedure call when N denotes a function call and appears as an
5590 actual parameter in the procedure call.
5592 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
5594 * freeze.adb (Check_Component_Storage_Order): If there is a clause
5595 for the component, also reject the attribute if the component
5596 doesn't end on a byte boundary and its scalar storage order is
5597 different from that of the enclosing record type.
5599 2017-04-28 Javier Miranda <miranda@adacore.com>
5601 * atree.ads (Info_Messages): Removed.
5602 (Warning_Info_Messages): New counter.

5631 2017-04-28 Bob Duff <duff@adacore.com>
5633 * sem_util.ads, sem_util.adb (Might_Raise): New function
5634 that replaces Is_Exception_Safe, but has the opposite
5635 sense. Is_Exception_Safe was missing various cases -- calls inside
5636 a pragma Debug, calls inside an 'if' or assignment statement,
5637 etc. Might_Raise now walks the entire subtree looking for things
5639 * exp_ch9.adb (Is_Exception_Safe): Remove.
5640 (Build_Protected_Subprogram_Body): Replace call to
5641 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
5642 constants where possible).
5643 * exp_ch7.adb: Rename Is_Protected_Body -->
5644 Is_Protected_Subp_Body. A protected_body is something different
5647 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
5649 * inline.adb (Expand_Inlined_Call): Initialize Targ1 variable.

5671 2017-04-28 Ed Schonberg <schonberg@adacore.com>
5673 * sem_ch13.adb (Analyze_Aspect_Specifications, case
5674 Interrupt_Handler and Attach_Handler): Generate reference
5675 to protected operation to prevent spurious warnings about
5676 unreferenced entities. Previous scheme failed with style checks
5679 2017-04-28 Ed Schonberg <schonberg@adacore.com>
5681 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
5682 that follows an expression function must not be relocated to
5683 the generated body, because it applies to the code that follows.
5685 2017-04-28 Gary Dismukes <dismukes@adacore.com>
5687 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
5688 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
5689 code that might violate the more stringent checking for 'Access
5690 introduced in Ada 2005.
5692 2017-04-28 Arnaud Charlet <charlet@adacore.com>
5694 * a-cforse.adb: minor style fix in comment.
5696 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
5698 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
5699 initialize Block_Decls variable.
5700 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
5701 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.
5702 * exp_disp.adb (Expand_Interface_Actuals): Initialize
5703 Formal_DDT and Actual_DDT variables.

5710 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
5712 2017-04-28 Ed Schonberg <schonberg@adacore.com>
5714 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
5715 node between access types, freeze the designated type as well,
5716 so that dispatch table pointers are created in the proper scope,
5717 and not in the constructed body of the expression function.
5719 2017-04-28 Bob Duff <duff@adacore.com>
5721 * alloc.ads (Nodes_Initial): Go back to previous value. The large
5722 value makes large compilations faster, but small compilations slower.
5724 2017-04-28 Arnaud Charlet <charlet@adacore.com>
5726 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
5728 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
5730 * erroutc.adb (Compilation_Errors): Do not consider info messages
5731 as suitable warnings when warnings must be treated as errors.
5732 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
5733 internally-generated packages when outputting completion
5735 * errout.adb (Output_Messages): Do not consider info messages as

5738 suitable warnings when warnings must be treated as errors.
5740 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
5742 * warnsw.ads: Minor fix for incorrect wording in comment.
5744 2017-04-28 Ed Schonberg <schonberg@adacore.com>
5746 * sem_res.adb (In_Instance_Code): New predicate in
5747 Valid_Conversion, to determine whether a type conversion appears
5748 as (or within) an actual for a formal object. Type conversions
5749 in instances are not rechecked in Valid_Conversion because
5750 visibility changes between generic location andi instance may
5751 lead to spurious errors, but conversions within an actual must be
5752 fully checked, and they are not fully resolved when pre-analyzing
5755 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
5757 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
5758 New_Copy_Tree instead of Relocate_Node as any subsequent copies
5759 of the relocated node will have mangled Parent pointers.
5760 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
5761 tables used in conjunction with entity and itype replication.
5762 (Visit_Entity): Rewrite the restriction on which entities
5763 require duplication. The restriction now includes all types.
5765 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
5767 * a-cofuse.ads, a-cfdlli.ads, a-cfhase.adb, a-cfhase.ads, a-cfinve.adb,

5781 2017-04-28 Ed Schonberg <schonberg@adacore.com>
5783 * sem_ch4.adb: Fix copy/pasto.
5785 2017-04-27 Tristan Gingold <gingold@adacore.com>
5787 * gcc-interface/Make-lang.in: Define EH_MECHANISM while building
5788 raise-gcc.c. Fix include search path for raise-gcc.c
5790 2017-04-27 Eric Botcazou <ebotcazou@adacore.com>
5792 * fe.h (Warn_On_Questionable_Layout): Declare.
5793 * warnsw.ads (Warn_On_Record_Holes): Move down.
5794 (Warn_On_Questionable_Layout): New boolean variable.
5795 (Warning_Record): Add Warn_On_Questionable_Layout field.
5796 * warnsw.adb (All_Warnings): Set Warn_On_Questionable_Layout.
5797 (Restore_Warnings): Likewise.
5798 (Save_Warnings): Likewise.
5799 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
5800 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
5801 components_to_record.
5802 (gnu_field_to_gnat): New function.
5803 (warn_on_field_placement): Likewise.
5804 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
5805 parameters. Rename local variables and adjust recursive call.
5806 Rework final scan of the field list and implement warnings on the
5807 problematic placement of specific sorts of fields.
5809 2017-04-27 Bob Duff <duff@adacore.com>
5811 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,
5812 * fname.ads, freeze.adb, inline.adb, lib.adb, lib.ads, lib-list.adb,

5815 * sem_ch4.adb, sem_ch6.adb, sem_ch8.adb, sem_ch9.adb, sem_elab.adb,
5816 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
5817 For efficiency, cache results of Is_Internal_File_Name and
5818 Is_Predefined_File_Name in the Units table. This avoids a lot
5819 of repeated text processing.
5821 2017-04-27 Emmanuel Briot <briot@adacore.com>
5823 * g-comlin.adb (Sort_Sections): remove useless test.
5825 2017-04-27 Claire Dross <dross@adacore.com>
5827 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
5828 allow the use of regular equality over elements in contracts.
5829 (Formal_Model): Ghost package containing model functions that are
5830 used in subprogram contracts.
5831 (Current_To_Last): Removed, model functions should be used instead.
5832 (First_To_Previous): Removed, model functions should be used instead.
5833 (Strict_Equal): Removed, model functions should be used instead.
5834 (No_Overlap): Removed, model functions should be used instead.
5835 (Equivalent_Keys): Functions over cursors are removed. They were
5836 awkward with explicit container parameters.
5837 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
5838 allow the use of regular equality over elements in contracts.
5839 (Formal_Model): Ghost package containing model functions that
5840 are used in subprogram contracts.
5841 (Current_To_Last): Removed, model functions should be used instead.
5842 (First_To_Previous): Removed, model functions should be used instead.
5843 (Strict_Equal): Removed, model functions should be used instead.
5844 (No_Overlap): Removed, model functions should be used instead.
5846 2017-04-27 Yannick Moy <moy@adacore.com>
5848 * gnat1drv.adb: Code cleanup.
5850 2017-04-27 Ed Schonberg <schonberg@adacore.com>
5852 * exp_util.adb (Replace_Entity): The prefix of a 'Result
5853 attribute reference in a post- condition is the subprogram to
5854 which the condition applies. If the condition is inherited
5855 by a type extension, the prefix becomes a reference to the
5856 inherited operation, but there is no need to create a wrapper
5857 for this operation, because 'Result is expanded independently
5858 when elaborating the postconditions.
5860 2017-04-27 Bob Duff <duff@adacore.com>
5862 * sinput.adb: Minor code cleanup.
5863 * namet.adb (Append): Create faster versions of
5864 Append(String) and Append(Name_Id) by using slice assignment
5866 * sem_util.adb (In_Instance): Speed this up by removing
5867 unnecessary tests; Is_Generic_Instance is defined for all
5869 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
5870 Remove unused function.
5871 * alloc.ads (Nodes_Initial): Use a much larger value, because
5872 the compiler was spending a lot of time copying the nodes table
5873 when it grows. This number was chosen in 1996, so is rather out
5874 of date with current memory sizes. Anyway, it's virtual memory.
5875 Get rid of Orig_Nodes_...; use Node_... instead.
5876 * atree.adb (Lock): Do not release the Nodes tables; it's a
5878 Orig_Nodes_ ==> Nodes_
5879 * nlists.adb: Orig_Nodes_ ==> Nodes_
5880 * g-table.adb: Remove unused "with" clause.
5881 * g-table.ads, table.ads: Remove Big_Table_Type, which should
5882 not be used by clients.
5883 * g-dyntab.adb (Last_Allocated): New function
5884 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
5886 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
5888 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated
5890 (Subtypes_Statically_Match): Remove duplicate check.
5891 * sem_prag.adb (Check_Arg_Is_External_Name): Remove duplicate check.
5893 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
5895 * exp_aggr.adb (Replace_Type): Remove the special processing
5896 for selected components.
5897 * exp_attr.adb (Expand_N_Attribute_Reference): Merge the
5898 processing for attributes Fixed_Value and Integer_Value.
5899 * exp_util.adb (Side_Effect_Free): Merge the processing for

5905 tokens function, not, overriding, and procedure.
5906 * sem_ch6.adb (Fully_Conformant_Expressions): Merge the processing
5907 for qualified expressions, type conversions, and unchecked

6414 abstract subprogram so that compiler does not reject a parameter
6415 of a primitive operation of a tagged type being frozen, when
6416 the untagged type of that parameter cannot be frozen.
6418 2017-04-27 Bob Duff <duff@adacore.com>

6441 * exp_ch4.adb (Insert_Dereference_Action):
6442 Do not adjust the address of a controlled object when the
6443 associated access type is subject to pragma No_Heap_Finalization.
6446 2017-04-27 Pierre-Marie de Rodat <derodat@adacore.com>
6448 * gcc-interface/utils.c (gnat_type_for_size): Set
6449 TYPE_ARTIFICIAL on created types.
6451 2017-04-27 Claire Dross <dross@adacore.com>
6453 * a-cfdlli.adb, a-cfdlli.ads (Formal_Model): Adapt to
6454 modifications in functional containers.
6455 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
6456 to improve readablity. Subprograms are separated between basic
6457 operations, constructors and properties. Universally quantified
6458 formulas in contracts are factorized in independant functions
6459 with a name and a comment. Names of parameters are improved.
6461 2017-04-27 Gary Dismukes <dismukes@adacore.com>
6463 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
6465 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6467 * sem_res.adb (Resolve_Type_Conversion): Do not
6468 install a predicate check here since this is already done during
6469 the expansion phase. Verify whether the operand satisfies the
6470 static predicate (if any) of the target type.
6471 * sem_ch3.adb (Analyze_Object_Declaration): Do
6472 not install a predicate check if the object is initialized by
6473 means of a type conversion because the conversion is subjected
6476 2017-04-27 Tristan Gingold <gingold@adacore.com>
6478 * raise.c (__gnat_builtin_longjmp): Remove.
6479 (__gnat_bracktrace):

6497 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
6498 in gnat1 and gnatbind.
6499 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
6500 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o

6508 modifications in functional containers.
6509 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
6510 to improve readablity. Subprograms are separated between basic
6511 operations, constructors and properties. Universally quantified
6512 formulas in contracts are factorized in independant functions
6513 with a name and a comment. Names of parameters are improved.
6515 2017-04-27 Gary Dismukes <dismukes@adacore.com>

6532 * a-except.ads, a-except.adb, a-exexpr.adb: Removed (will be
6533 replaced by their variants).

6543 * s-excmac-gcc.ads, s-excmac-gcc.adb,
6544 s-excmac-arm.ads, s-excmac-arm.adb (New_Occurrence): Rewrite it in
6547 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6549 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
6550 the loop which detects potential enclosing transient scopes. The
6551 loop now terminates much earlier as transient scopes are bounded
6552 by packages and subprograms.
6554 2017-04-27 Claire Dross <dross@adacore.com>
6556 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
6557 allow the use of regular equality over elements in contracts.
6558 (Cursor): Type is now public so that it can be used in
6560 (Formal_Model): Ghost package containing
6561 model functions that are used in subprogram contracts.
6562 (Current_To_Last): Removed, model functions should be used
6564 (First_To_Previous): Removed, model functions should
6566 (Strict_Equal): Removed, model functions
6567 should be used instead.
6568 (Append): Default parameter value
6569 replaced by new wrapper to allow more precise contracts.
6570 (Insert): Default parameter value replaced by new wrapper to
6571 allow more precise contracts.
6572 (Delete): Default parameter
6573 value replaced by new wrapper to allow more precise contracts.
6574 (Prepend): Default parameter value replaced by new wrapper to
6575 allow more precise contracts.
6576 (Delete_First): Default parameter
6577 value replaced by new wrapper to allow more precise contracts.

6583 * exp_spark.adb (Expand_SPARK): Perform specialized expansion
6584 for object declarations.
6585 (Expand_SPARK_N_Object_Declaration): New routine.

6587 Default_Initial_Condition procedure of a type under the SPARK
6588 elaboration checks umbrella.
6590 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>

6599 * adaint.c (__gnat_get_current_dir): Return 0 in length if
6601 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
6602 exception if getcwd failed.

6611 * debug.adb Change the documentation of switch -gnatd.s.
6612 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
6613 to manage the secondary stack when an enclosing scope already
6614 performs this functionality (aka relaxed management). Switch
6615 -gnatd.s may be used to force strict management in which case
6616 the block will manage the secondary stack unconditionally. Add
6617 a guard to stop the traversal when encountering a package or a
6620 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6622 * sem_res.adb (Resolve_Call): Refine further the handling of
6623 limited views of return types in function calls. If the function
6624 that returns a limited view appears in the current unit,
6625 we do not replace its type by the non-limited view because
6626 this transformation is performed int the back-end. However,
6627 the type of the call itself must be the non-limited view, to
6628 prevent spurious resolution errors.
6630 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6632 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
6633 Removed, proposed implementation using generics for class-wide
6634 preconditions proved impractical.
6635 (Class_Wide_Clone): New attribute of subprogram. Designates
6636 subprogram created for primitive operations with class-wide
6637 pre/postconditions that contain calls to other primitives. The
6638 clone holds the body of the original primitive, but the
6639 pre/postonditions do not apply to it. The original body is
6640 rewritten as a wrapper for a call to the clone.
6641 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
6642 the flag is set, no code for the corresponding pre/postconditions
6643 is inserted into its body.
6645 2017-04-27 Bob Duff <duff@adacore.com>
6647 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore
6648 Scalar_Storage_Order if -gnatI is given.
6649 * sem_prag.adb (Analyze_Pragma): Ignore
6650 Default_Scalar_Storage_Order if -gnatI is given.

6658 * a-cofuse.ads (Add): Adapt to the new API of Base.Add.
6659 (Remove): New function that removes an element from a set.
6660 * a-cofuve.ads (Add): Adapt to the new API of Base.Add.
6661 (Remove): New function that removes an element from a sequence.
6662 (Insert): New function that adds anywhere in a sequence.

6675 of attribute 'Result is not considered a violation of pragma
6678 2017-04-27 Justin Squirek <squirek@adacore.com>
6680 * cstand.adb (Create_Standard): Correctly set
6681 Directly_Designated_Type for Any_Access.

6691 private child of Ada.Containers used to implement all functional
6693 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
6694 child of Ada.Containers. It provides functional indefinite unbounded
6695 maps which can be used as high level models for specification
6697 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
6698 child of Ada.Containers. It provides functional indefinite unbounded
6699 sets which can be used as high level models for specification
6701 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
6702 child of Ada.Containers. It provides functional indefinite unbounded
6703 vectors which can be used as high level models for specification
6705 * Makefile.rtl: Add new packages.
6706 * impunit.adb: Add new packages.
6708 2017-04-27 Gary Dismukes <dismukes@adacore.com>

6712 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6714 * sem_ch12.adb (Analyze_Associations): minor reformatting.
6715 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
6716 point type actual that has user-defined arithmetic primitives,
6717 when there is a previous actual for a formal package that defines
6718 a fixed-point type with the parent user-defined operator.
6720 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6722 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
6723 * sem_attr.adb (Resolve_Attribute): Generate a range check when
6724 the component type allows range checks.
6726 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6728 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
6729 corresponding declaration, because formal derived types are
6730 rewritten as private extensions.
6732 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6734 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
6735 dimensions of operands if node has been analyzed already, because
6736 previous analysis and dimension checking will have removed the
6737 dimension information from the operands.
6739 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6741 * debug.adb: Document the use of switch -gnatd.s.
6742 * einfo.ads Update the documentation on attribute
6743 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
6744 the uses of these attributes from certain entities.
6745 * exp_ch7.adb (Make_Transient_Block): Reimplement the circuitry
6746 which determines whether the block should continue to manage
6747 the secondary stack.
6748 (Manages_Sec_Stack): New routine.
6750 2017-04-27 Bob Duff <duff@adacore.com>

6756 * sinfo.ads: Update the section on Ghost mode. Add
6757 a section on SPARK mode. Update the placement of section on
6758 expression functions.
6760 2017-04-27 Bob Duff <duff@adacore.com>

6801 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
6802 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
6803 Ada_2012 instead of Ada_2005 to be compatible with the above
6805 * bindgen.adb: Silence new warning on pragma Ada_95.
6807 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
6809 * checks.adb (Generate_Range_Check): Revert part of previous change.

6815 parameter association in a procedure call.
6817 2017-04-25 Olivier Ramonat <ramonat@adacore.com>
6819 * prj-proc.adb, sem_util.adb, s-stposu.adb, sem_attr.adb, prj-conf.ads:
6820 Fix spelling mistakes.
6822 2017-04-25 Bob Duff <duff@adacore.com>
6824 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
6825 * sinput-p.adb: Use regular fat pointers, with bounds checking,
6826 for source buffers. Fix misc obscure bugs.
6827 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
6828 checking, for source buffers. Modify representation clause for
6829 Source_File_Record as appropriate. Move Source_File_Index_Table
6830 from spec to body, because it is not used outside the body.
6831 Move Set_Source_File_Index_Table into the private part, because
6832 it is used only in the body and in children. Use trickery to
6833 modify the dope in the generic instantiation case. It's ugly,
6834 but not as ugly as the previous method. Fix documentation.
6835 Remove obsolete code.
6836 * fname-sf.adb, targparm.adb: Fix misc out-of-bounds
6837 indexing in source buffers.

6851 expander is not active or when index/range checks are suppressed
6853 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
6854 Remove variants that include a Supress parameter. These routines
6855 are never used, and were introduced before the current scope-based
6856 check suppression method.
6858 2017-04-25 Vasiliy Fofanov <fofanov@adacore.com>
6860 * prj-part.adb, cstreams.c, osint.adb, osint.ads: Remove VMS specific

6873 (Known_Null): Moved to Sem_Util.
6874 * sem_util.adb Add new enumeration type Null_Status_Kind.
6875 (Known_Non_Null): Moved from Exp_Util. Most of the logic in
6876 this routine is now carried out by Null_Status.
6877 (Known_Null): Moved from Exp_Util. Most of the logic in this routine
6878 is now carried out by Null_Status.
6879 (Null_Status): New routine.

6881 (Known_Null): Moved from Exp_Util.
6883 2017-04-25 Ed Schonberg <schonberg@adacore.com>
6885 * sem_ch6.adb (Analyze_Expression_Function): Do not report an
6886 error on the return type of an expression function that is a
6887 completion, if the type is derived from a generic formal type.
6889 2017-04-25 Ed Schonberg <schonberg@adacore.com>

6892 conversion are those of the target type.

6906 errout.adb, sinput.adb, sinput.ads, cstand.adb, scn.adb,
6907 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
6908 the Internal_Source buffer. This removes the incorrect call to "="
6909 the customer noticed.
6910 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
6911 eventually need to eliminate them altogether. Or else get rid
6912 of zero-origin addressing.

7429 the controlliong argument from calls to primitives in the case
7430 of the formal parameter being an class-wide abstract type.
7431 * sem_ch3.adb (Build_Assertion_Bodies_For_Type): Almost identical
7432 to the change made to Freeze_Type in exp_ch3. Add a condition
7433 to treat interface types as a partial view.
7434 * sem_prag.adb (Analyze_Pragma): Modify parameters in the call
7435 to Build_Invariant_Procedure_Declaration to properly generate a
7436 "partial" invariant procedure when Typ is an interface.
7438 2017-04-25 Bob Duff <duff@adacore.com>
7440 * a-numeri.ads: Go back to using brackets encoding for the Greek
7443 2017-04-25 Ed Schonberg <schonberg@adacore.com>
7445 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
7446 (10-15): if derived type T with progenitors is abstract,
7447 and primitive P of this type inherits non-trivial classwide
7448 preconditions from both a parent operation and from an interface
7449 operation, then the inherited operation is abstract if the parent
7450 operation is not null.
7451 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
7452 with Covered_Interface_Op to yield the actual interface operation
7453 that is implemented by a given inherited operation.
7455 2017-04-25 Javier Miranda <miranda@adacore.com>
7457 * exp_ch4.adb (Expand_N_Op_Expon): Relocate left
7458 and right operands after performing the validity checks. Required
7459 because validity checks may remove side effects from the operands.
7461 2017-04-25 Javier Miranda <miranda@adacore.com>
7463 * exp_attr.adb (Attribute_Unrestricted_Access):
7464 Do not disable implicit type conversion. Required to generate
7465 code that displaces the pointer to reference the secondary

7476 values, and comparing them must use Expr_Value_S.
7478 2017-04-25 Ed Schonberg <schonberg@adacore.com>
7480 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
7481 dereference is introduced for the object, and the object is
7482 overloaded, do not check whether it is aliased, because it may
7483 include an implicit dereference.
7484 * sem_type.adb (Disambiguate): If two interpretations are access
7485 attribute types with the same designated type keep either of
7486 them and do not report an ambiguity. A true ambiguity will be
7489 2017-04-25 Bob Duff <duff@adacore.com>
7491 * a-numeri.ads: Change the encoding of Greek letter Pi from
7492 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
7493 to indicate the encoding. We considered using a byte order mark
7494 (BOM), but that causes various trouble (misc software eats the
7495 BOM, if you have a patch with a BOM, then it's not at the start
7496 of the patch, so it's not a BOM, the BOM affects with-ing files,
7498 * scng.adb, s-wchcnv.adb: Minor.

7510 moved here from sem_ch3.
7511 * sem_ch8.adb (Analyze_Subprogram_Renaming): Implement legality
7512 check given in RM 6.1.1 (17) concerning renamings of overriding
7513 operations that inherits class-wide preconditions from ancestor
7516 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

7534 restrictions when the handler is internally generated and the
7537 2017-04-25 Ed Schonberg <schonberg@adacore.com>
7539 * sem_ch3.adb (Has_Non_Trivial_Precondition): New predicate to
7540 enforce legality rule on classwide preconditions inherited from
7541 both an ancestor and a progenitor (RM 6.1.1 (10-13).
7542 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
7543 subprogram need not be dispatching if it appears in a precondition
7544 for an abstract or null subprogram.
7546 2017-04-25 Gary Dismukes <dismukes@adacore.com>
7548 * sem_ch10.adb: Minor typo fix.
7550 2017-04-25 Arnaud Charlet <charlet@adacore.com>
7552 * gcc-interface/Makefile.in: Cleanup VxWorks targets.
7554 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
7556 * fname.adb (Is_Internal_File_Name): Arrange for the slices to
7557 have a length which is a power of 2.
7558 (Is_Predefined_File_Name): Likewise. Adjust comment.
7560 2017-04-25 Bob Duff <duff@adacore.com>
7562 * exp_aggr.adb (Component_Count): Protect the
7563 arithmetic from attempting to convert a value >= 2**31 to Int,
7564 which would otherwise raise Constraint_Error.
7566 2017-04-25 Bob Duff <duff@adacore.com>
7568 * opt.ads (Locking_Policy): Fix incorrect documentation. The
7569 first character of the policy name is not unique.
7571 2017-04-25 Bob Duff <duff@adacore.com>
7573 * s-fileio.adb (Name): Raise Use_Error if the file is a temp file.
7574 * s-ficobl.ads (Is_Temporary_File): Remove incorrect comment
7575 about this flag not being used. It was already used, and it is

7592 Save and restore the value of global flag
7593 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value
7594 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance when either
7595 the corresponding spec or the body must ignore all SPARK_Mode
7596 pragmas found within.
7597 (Analyze_Subprogram_Declaration): Mark
7598 the spec when it needs to ignore all SPARK_Mode pragmas found
7599 within to allow the body to infer this property in case it is
7600 instantiated or inlined later.
7601 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
7602 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
7603 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
7604 when the corresponding spec also ignored all SPARK_Mode pragmas
7606 (Analyze_Package_Declaration): Mark the spec when
7607 it needs to ignore all SPARK_Mode pragmas found within to allow
7608 the body to infer this property in case it is instantiated or
7610 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
7611 Save and restore the value of flag
7612 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
7613 formal spec when it needs to ignore all SPARK_Mode
7614 pragmas found within to allow the body to infer this
7615 property in case it is instantiated or inlined later.
7616 (Analyze_Package_Instantiation): Save and restore the value
7617 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
7618 the instance spec when it needs to ignore all SPARK_Mode

7622 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
7623 instance spec and anonymous package when they need to ignore
7624 all SPARK_Mode pragmas found within to allow the body to infer

7626 (Instantiate_Package_Body): Save and restore the value of global
7627 flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set the value of

7637 Ignore_Pragma_SPARK_Mode.
7638 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
7639 all SPARK_Mode pragmas defined within yields mode "off".
7641 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
7643 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.

7660 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
7662 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
7663 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
7664 variable and set it to True whenever the main hash table is
7665 populated. Short- circuit the Assoc function if it is false
7666 and add associated guards.
7668 2017-04-25 Olivier Hainque <hainque@adacore.com>
7670 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
7671 specs without elaboration code that have an elaboration counter
7672 nevertheless, e.g. when compiled with -fpreserve-control-flow.
7673 * sem_ch10.adb (Analyze_Compilation_Unit):
7674 Set_Elaboration_Entity_Required when requested to preserve
7675 control flow, to ensure the unit elaboration is materialized at
7676 bind time, resulting in the inclusion of the unit object file
7677 in the executable closure at link time.
7679 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
7681 * exp_dbug.adb: In Debug_Renaming_Declaration,
7682 when dealing with indexed component, accept to produce a renaming
7683 symbol when the index is an IN parameter or when it is a name
7684 defined in an outer scope.
7686 2017-04-25 Yannick Moy <moy@adacore.com>
7688 * errout.adb (Error_Msg): Adapt continuation
7689 message in instantiations and inlined bodies for info messages.
7691 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
7693 * fname.adb (Has_Internal_Extension): Add pragma Inline.
7694 Use direct 4-character slice comparisons.
7696 pragma Inline. (Has_Suffix): Delete.
7697 (Is_Internal_File_Name):
7698 Test Is_Predefined_File_Name first.
7699 (Is_Predefined_File_Name):
7700 Use direct slice comparisons as much as possible and limit all
7701 comparisons to at most 8 characters.
7703 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
7705 * checks.adb (Insert_Valid_Check): Code cleanup.
7706 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
7707 (Expand_Actuals): Generate proper copy-back for a validation
7708 variable when it acts as the argument of a type conversion.
7709 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
7710 predicate to operate on type qualifications.
7712 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
7714 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
7717 2017-04-25 Bob Duff <duff@adacore.com>
7719 * sem_prag.adb (No_Return): Give an error if the pragma applies
7720 to a body. Specialize the error for the specless body case,
7721 as is done for (e.g.) pragma Convention.
7722 * debug.adb: Add switch -gnatd.J to disable the above legality
7723 checks. This is mainly for use in our test suite, to avoid
7724 rewriting a lot of illegal (but working) code. It might also
7725 be useful to customers. Under this switch, if a pragma No_Return
7726 applies to a body, and the procedure raises an exception (as it
7727 should), the pragma has no effect. If the procedure does return,
7728 execution is erroneous.
7730 2017-04-25 Bob Duff <duff@adacore.com>
7732 * exp_ch6.adb (Expand_Actuals): This is the
7733 root of the problem. It took N as an 'in out' parameter, and in
7734 some cases, rewrote N, but then set N to Original_Node(N). So
7735 the node returned in N had no Parent. The caller continued
7736 processing of this orphaned node. In some cases that caused a
7737 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
7738 and trips over the Empty Parent). The solution is to make N an
7739 'in' parameter. Instead of rewriting it, return the list of
7740 post-call actions, so the caller can do the rewriting later,
7741 after N has been fully processed.
7742 (Expand_Call_Helper): Move most of Expand_Call here. It has
7743 too many premature 'return' statements, and we want to do the
7744 rewriting on return.
7745 (Insert_Post_Call_Actions): New procedure to insert the post-call
7746 actions in the appropriate place. In the problematic case,
7747 that involves rewriting N as an Expression_With_Actions.
7748 (Expand_Call): Call the new procedures Expand_Call_Helper and
7749 Insert_Post_Call_Actions.
7751 2017-04-25 Ed Schonberg <schonberg@adacore.com>
7753 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
7754 properly type derived from generic formal types, to handle
7755 properly modified version of ACATS 4.1B B611017.
7757 2017-04-25 Javier Miranda <miranda@adacore.com>
7759 * exp_unst.adb (Subp_Index): Adding missing
7760 support for renamings and functions that return a constrained
7761 array type (i.e. functions for which the frontend built a
7762 procedure with an extra out parameter).
7764 2017-04-25 Pascal Obry <obry@adacore.com>
7766 * s-string.adb: Minor code clean-up.
7768 2017-04-25 Bob Duff <duff@adacore.com>

7773 function for Non_Blocking_Wait_Process.
7775 2017-04-25 Bob Duff <duff@adacore.com>
7777 * prep.adb (Preprocess): Remove incorrect
7778 Assert. Current character can be ASCII.CR.
7780 2017-04-25 Ed Schonberg <schonberg@adacore.com>
7782 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
7783 convention Stdcall, which has a number of exceptions. Convention
7784 is legal on a component declaration whose type is an anonymous
7785 access to subprogram.
7787 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
7789 * sem_ch4.adb: sem_ch4.adb Various reformattings.
7790 (Try_One_Prefix_Interpretation): Use the base type when dealing
7791 with a subtype created for purposes of constraining a private
7792 type with discriminants.
7794 2017-04-25 Javier Miranda <miranda@adacore.com>
7796 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.
7797 * warnsw.ads, warnsw.adb (All_Warnings): Set warning on late
7798 dispatching primitives (Restore_Warnings): Restore warning on
7799 late dispatching primitives (Save_Warnings): Save warning on late
7800 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
7801 to enable/disable this warning.
7802 (WA_Warnings): Set warning on late dispatching primitives.
7803 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
7804 that its parent type has a private extension.
7805 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
7807 * usage.adb: Document -gnatw.j and -gnatw.J.
7809 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
7811 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
7814 2017-04-25 Bob Duff <duff@adacore.com>
7816 * binde.adb (Validate): Do not pass dynamic strings
7817 to pragma Assert, because older compilers do not support that.
7819 2017-04-25 Bob Duff <duff@adacore.com>
7821 * s-fileio.adb (Close): When a temp file is
7822 closed, delete it and clean up its Temp_File_Record immediately,
7823 rather than waiting until later.
7824 (Temp_File_Record): Add File
7825 component, so Close can know which Temp_File_Record corresponds
7826 to the file being closed.
7827 (Delete): Don't delete temp files,
7828 because they are deleted by Close.
7829 (Open): Set the File component
7830 of Temp_File_Record. This requires moving the creation of the
7831 Temp_File_Record to the end, after the AFCB has been created.
7833 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
7835 * checks.adb (Insert_Valid_Check): Do not generate
7836 a validity check when inside a generic.

7850 concerning inheritance of class-wide preconditions do not apply
7853 2017-04-25 Bob Duff <duff@adacore.com>
7855 * s-ficobl.ads: Minor comment fix.
7857 2017-04-25 Yannick Moy <moy@adacore.com>
7859 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
7860 conversions from float to integer in GNATprove mode.
7861 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
7862 to call Apply_Type_Conversion_Checks, so that range checks
7863 are properly positioned when needed on conversions, including
7864 when converting from float to integer. (Determine_Range): In
7865 GNATprove mode, take into account the possibility of conversion
7866 from float to integer.
7867 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
7868 check on conversions from fixed-point to integer, not anymore
7869 on conversions from floating-point to integer, when in GNATprove
7872 2017-04-25 Yannick Moy <moy@adacore.com>
7874 * checks.adb (Determine_Range_R): Special case type conversions
7875 from integer to float in order to get bounds in that case too.
7876 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
7877 mode, for computations involved in interval checking.

7889 (Validated_Object): New routine along with pragma Inline.
7890 (Set_Validated_Object): New routine along with pragma Inline.
7891 * exp_attr.adb (Make_Range_Test): Add processing for validation
7892 variables to avoid extra reads and copies of the prefix.
7893 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
7894 variables in order to reflect any changes done in the variable
7895 back into the original object.
7896 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
7897 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

7903 generate Finalize_Address routines for CodePeer.
7905 2017-04-25 Ed Schonberg <schonberg@adacore.com>
7907 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
7908 Analyze_Pre_Post_Condition, to implement the legality checks
7909 mandated by AI12-0131: Pre'Class shall not be specified for an
7910 overriding primitive subprogram of a tagged type T unless the
7911 Pre'Class aspect is specified for the corresponding primitive
7912 subprogram of some ancestor of T.
7914 2017-04-25 Bob Duff <duff@adacore.com>
7916 * sem_ch8.adb (Use_One_Type): If a use_type_clause
7917 is redundant, set its Used_Operations to empty. This is only
7918 necessary for use clauses that appear in the parent of a generic
7919 child unit, because those use clauses get reanalyzed when we
7920 instantiate the generic, and we don't want the Used_Operations
7921 carried over from the original context (where it was probably
7924 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

7949 tag of a tagged result.
7950 * exp_intr.adb (Expand_Dispatching_Constructor_Call):
7951 if CodePeer_Mode is True, then don't generate the
7952 tag checks for the result of call to an instance of
7953 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
7954 descendant of" check and the accessibility check).

7965 (Expand_Concatenate): When optimization is enabled, also expand
7966 the operation out-of-line if the concatenation is present within
7967 the expression of the declaration of a library-level object and
7968 not only if it is the expression of the declaration.
7970 2017-04-25 Bob Duff <duff@adacore.com>
7972 * freeze.adb (Freeze_Object_Declaration): Do
7973 not Remove_Side_Effects if there is a pragma Linker_Section,
7974 because in that case we want static initialization in the
7975 appropriate section.
7977 2017-04-25 Gary Dismukes <dismukes@adacore.com>
7979 * exp_dbug.adb: Minor rewording and reformatting.
7981 2017-04-25 Ed Schonberg <schonberg@adacore.com>
7983 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
7984 handle the proposed changes to rules concerning potentially
7985 unevaluated expressions, to include selected components that
7986 do not depend on discriminants, and indexed components with

8008 renaming entity for debug information, mark the entity as needing debug
8009 info if it comes from sources.
8011 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8013 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
8014 restriction converning the use of 'Address where the prefix is

8028 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8030 * sem_ch3.adb (Check_Entry_Contract): Call
8031 Preanalyze_Spec_Expression so that resolution takes place as well.
8032 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
8033 internal calls that appear in preconditions of protected
8034 operations, in default values for same, and in contract guards
8035 for contract cases in SPARK.
8037 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8039 * a-numaux.ads: Fix description of a-numaux-darwin
8041 (Double): Define to Long_Float.

8046 * a-numaux-x86.ads: Fix package description.
8047 * a-numaux-x86.adb (Is_Nan): Minor tweak.
8048 (Reduce): Adjust and complete description. Call Is_Nan instead of
8049 testing manually. Use an integer temporary to hold rounded value.
8050 * a-numaux-darwin.adb (Reduce): Likewise.
8051 (Is_Nan): New function.
8053 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8055 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
8056 on analysis of prefix whose type is a current instance of a
8057 synchronized type, but where the prefix itself is an entity that
8060 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8062 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
8063 the identity of callable entities therein, because they have been
8064 properly resolved, and prefixed calls may have been rewritten
8067 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
8069 * exp_ch3.adb (Build_Init_Statements): Convert
8070 the expression of the pragma/aspect Secondary_Stack_Size to

8083 * s-osinte-freebsd.ads: Minor comment tweaks
8085 2017-04-25 Javier Miranda <miranda@adacore.com>
8087 * urealp.adb (UR_Write): Reverse previous patch
8088 adding documentation on why we generate multiplications instead
8089 of divisions (needed to avoid expressions whose computation with
8090 large numbers may cause division by 0).
8092 2017-04-25 Bob Duff <duff@adacore.com>
8094 * erroutc.adb (Set_Specific_Warning_Off,
8095 Set_Warnings_Mode_Off): Use the correct source file for
8096 Stop. Was using Current_Source_File, which is only valid during
8097 parsing. Current_Source_File will have a leftover value from
8098 whatever file happened to be parsed last, because of a with_clause
8101 2017-04-25 Bob Duff <duff@adacore.com>
8103 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
8104 to In_Predefined_Unit, but including GNAT units.
8105 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
8106 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
8107 because Should_Ignore_Pragma was not working reliably outside
8108 the parser, because Current_Source_File is not valid.
8109 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
8110 * par-prag.adb: Call Should_Ignore_Pragma_Par.

8147 Build_Invariant_Procedure_Body.
8148 (Build_Invariant_Procedure_Body):
8149 Remove refactored calls and integrated code from
8150 Add_Parent_Invariants and Add_Interface_Invariants.
8152 2017-04-25 Johannes Kanig <kanig@adacore.com>
8154 * errout.adb (Output_Messages): Adjust computation of total
8156 * erroutc.adb (Error_Msg): In statistics counts, deal
8157 correctly with informational messages that are not warnings.

8169 2017-04-25 Justin Squirek <squirek@adacore.com>
8171 * sem_ch3.adb (Analyze_Declarations): Minor
8172 correction to comments, move out large conditional and scope
8173 traversal into a predicate.
8174 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
8177 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8179 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
8180 of prefix whose type is a current instance of a synchronized
8181 type. If the prefix is an object this is an external call (or
8182 requeue) that can only access public operations of the object. The
8183 previous predicate was too restrictive, and did not allow public
8184 protected operations, only task entries.
8186 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8188 * sem_ch5.adb, fname.adb: Minor reformatting.
8190 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8192 * einfo.adb (Is_Anonymous_Access_Type): New routine.
8193 * einfo.ads Update the placement of
8194 E_Anonymous_Access_Subprogram_Type along with all subtypes that
8196 (Is_Anonymous_Access_Type): New routine.
8197 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
8198 master for an access type subject to pragma No_Heap_Finalization.
8199 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
8200 allocated or deallocated does not finalization actions if the
8201 associated access type is subject to pragma No_Heap_Finalization.
8202 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
8203 * par-prag.adb Pragma No_Heap_Finalization does not need special
8204 processing from the parser.
8205 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
8206 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
8207 * sem_prag.adb Add an entry in table Sig_Flags for pragma
8208 No_Heap_Finalization.
8209 (Analyze_Pragma): Add processing for
8210 pragma No_Heap_Finalization. Update various error messages to
8211 use Duplication_Error.
8212 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
8213 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
8214 and corresponding pragma id.
8216 2017-04-25 Bob Duff <duff@adacore.com>
8218 * freeze.adb (Freeze_Record_Type): Use the
8219 underlying type of the component type to determine whether it's
8220 elementary. For representation clause purposes, a private type
8221 should behave the same as its full type.
8222 * fname.ads, fname.adb (Is_Predefined_File_Name):
8223 Make sure things like "system.ali" are recognized as predefined.
8225 2017-04-25 Javier Miranda <miranda@adacore.com>

8231 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
8232 element iterator when the name is an overloaded function call,
8233 one of whose interpretations yields an array.
8235 2017-04-25 Bob Duff <duff@adacore.com>
8237 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
8238 Is_Internal_Unit_Name): New functions for operating on unit
8239 names, as opposed to file names. There's some duplicated code
8240 with fname.adb, which is unfortunate, but it seems like we don't
8241 want to add dependencies here.
8242 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
8243 to Is_Predefined_Unit_Name; the former was wrong, because Uname
8244 is not a file name at all.
8245 * fname.ads, fname.adb: Document the fact that
8246 Is_Predefined_File_Name and Is_Internal_File_Name can be called
8247 for ALI files, and fix the code so it works properly for ALI
8248 files. E.g. these should return True for "system.ali".
8250 2017-04-25 Justin Squirek <squirek@adacore.com>
8252 * exp_util.adb (Add_Invariant): Removed,
8253 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
8254 and Add_Own_Invariant. (Add_Invariant_Check): Used
8255 for adding runtime checks from any kind of invariant.
8256 (Add_Inherited_Invariant): Generates invariant checks for
8257 class-wide invariants (Add_Interface_Invariants): Removed, code
8258 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
8259 Create a types own invariant procedure (Add_Parent_Invariants):
8260 Removed, code moved to Build_Invariant_Procedure_Body
8261 (Build_Invariant_Procedure_Body): Add refactored calls
8262 and integrated code from Add_Parent_Invariants and
8263 Add_Interface_Invariants.
8264 (Process_Type): Removed, the
8265 relavant code was inlined into both Add_Own_Invariant and
8266 Add_Inherited_Invariant.
8268 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8270 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

8287 and Build_Invariant_Procedure_Declaration.
8288 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
8289 and Build_Invariant_Procedure_Declaration from exp_ch7
8290 and break-out Is_Untagged_Private_Derivation from
8291 Build_Invariant_Procedure_Body.
8292 (Replace_Type_References):
8293 Append an extra parameter to allow for dispatching replacements
8294 and add the corrasponding logic.
8295 (Type_Invariant): Remove
8296 Replace_Typ_Refs and replace its references with calls to
8297 Replace_Type_References.
8298 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
8300 2017-04-25 Bob Duff <duff@adacore.com>
8302 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
8303 that returns True when appropriate.
8304 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
8305 when compiling predefined files.
8306 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
8307 "gnat.adc" should not be considered a predefined file name.
8308 That required (or at least encouraged) a lot of cleanup of global
8309 variable usage. We shouldn't be communicating information via
8310 the global name buffer.
8311 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
8312 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

8332 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
8333 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
8334 Add String_To_Name with no side effects.
8336 2017-04-25 Justin Squirek <squirek@adacore.com>
8338 * sem_ch3.adb (Analyze_Declarations): Add
8339 additional condition for edge case.

8343 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
8344 reserved words inside pragmas. This is necessary to allow the
8345 pragma name Interface to be used in pragma Ignore_Pragma.

8371 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
8372 the first pass over an assignment statement with target names,
8373 to prevent the generation of subtypes (such as discriminated
8374 record components)that may carry the target name outside of the
8375 tree for the assignment. The subtypes will be generated when
8376 the assignment is reanalyzed in full.
8377 (Analyze_Target_Name): Handle properly class-wide types.

8387 and resolve the triaged expression because all substitutions
8388 refer to the proper entities. Update the replacement of

8391 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
8392 are now only processed when freezing occurs. Build a body only

8409 properties of the private type to the full view in case the full
8410 view derives from a parent type and inherits a DIC pragma.
8411 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
8412 DIC pragma is placed at the top of a declarative region.
8414 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

8417 int to avoid overflow checks.
8419 2017-04-25 Ed Schonberg <schonberg@adacore.com>

8422 the error message when the attribute reference is an actual in
8423 a call to a subprogram inherited from a generic formal type with
8424 unknown discriminants, which makes the subprogram and its formal
8425 parameters intrinsic (see RM 6.3.1 (8) and (13)).
8427 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8429 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

9136 (Check_Dependency_Clause): Properly detect a match between two
9137 'Result attributes. Update the various post-match cases to use

9201 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
9202 an object declaration for an array type with a modular index type
9203 with the size of Long_Long_Integer. Special processing is needed
9204 in this case to compute reliably the size of the object, and
9205 eventually to raise Storage_Error, when wrap-around arithmetic
9206 might compute a meangingless size for the object.
9208 2017-01-23 Justin Squirek <squirek@adacore.com>

9215 * sem_res.adb (Resolve_Call): In the part of the code where
9216 it is deciding whether to turn the call into an indexed
9217 component, avoid doing so if the call is to an instance of
9218 Unchecked_Conversion. Otherwise, the compiler turns it into an
9219 indexed component, and resolution of that turns it back into a
9220 function call, and so on, resulting in infinite recursion.
9221 * sem_util.adb (Needs_One_Actual): If the first formal has a
9222 default, then return False.

9267 2017-01-20 Ed Schonberg <schonberg@adacore.com>
9269 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
9270 must be treated as delayed aspect even if the expression is
9271 a literal, because the aspect affects the freezing and the

9293 the prefix is not null) when the prefix denotes an object of an
9294 access type; that is, when there is an implicit dereference.

9324 returns a limited view of a type and at the point of the call the
9325 function is not declared in the extended main unit then replace
9326 it with the non-limited view, which must be available. If the
9327 called function is in the extended main unit then no action is
9328 needed since the back-end handles this case.

9342 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
9343 base type differs from that of the completion and the private
9344 subtype is an itype (created for a constraint on an access
9345 type e.g.), set Delayed_Freeze on both to prevent out-of-scope

9641 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
9642 (Build_Derived_Enumeration_Type): If the derived type inherits a
9643 dynamic predicate from its parent, the bounds of the type must
9644 freeze because an explicit constraint is constructed for the
9645 type and the corresponding range is elaborated now.

9730 2017-01-19 Ed Schonberg <schonberg@adacore.com>
9732 * sem_ch4.adb (Diagnose_Call): Improve error message when a
9733 selected component has a prefix that might be interpreted
9734 as a parameterless function call, but none of the candidate
9735 interpretations is parameterless, and there is a hidden homonym
9736 of the prefix that is a package.
9737 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
9738 interpreted as a parameterless function call and its analysis
9739 fails, do not call Analyze_Selected_Component.

9743 * sem_util.ads: Add new Use_Full_View Boolean parameter to
9745 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
9746 calls to a newly-defined Scalar_Range_Of_Right_View function.

9754 from repeated code of Traverse_Compilation_Unit.
9755 (Traverse_Declaration_Or_Statement): fixed detection of
9756 generic subprograms and packages; also, iteration over case
9757 statement alternatives rewritten to avoid testing if the first
9758 alternative is present (since it must be present due to Ada
9759 syntax restrictions).
9761 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
9763 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as

9774 identifier nodes that do not come from source, to handle properly
9775 dimensionality check within an inlined body which inclddes both
9776 original operands and rewritten operands. This removes spurious
9777 dimensionality errors in the presence of front-end inlining,
9778 as well as in SPARK mode.

9851 * sem_ch6.adb (Cloned_Expression): New subprogram.
9852 (Freeze_Expr_Types): Complete previous patch since the expression
9853 of an expression-function may have iterators and loops with
9854 defining identifiers which, as part of the preanalysis of the
9855 expression, may be left decorated with itypes that will not be
9856 available in the tree passed to the backend.
9858 2017-01-13 Ed Schonberg <schonberg@adacore.com>

9876 Ensure that the input body is a subprogram body before trying to
9877 determine whether it denoted an expression function. Note that
9878 subprogram body stubs cannot denote expression functions.

9896 2017-01-13 Bob Duff <duff@adacore.com>
9898 * binde.adb (Elab_New): New elaboration order algorithm
9899 that is expected to cause fewer ABE issues. This is a work in
9900 progress. The new algorithm is currently disabled, and can be
9901 enable by the -dp switch, or by modifying the Do_Old and Do_New
9902 etc. flags and rebuilding. Experimental code is included to
9903 compare the results of the old and new algorithms.
9904 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
9905 can have multiple of these tables, so the old and new algorithms
9907 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
9908 parameter of type array. This avoids the global variable, and
9909 allows bounds checking (which is normally defeated by the tables
9910 packages). It also ensures that the Elab_Order is read-only
9912 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
9913 subprograms that need it, as above.
9914 * debug.adb: Document new -dp switch. Modify doc of old -do
9916 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
9917 and Bindgen. Move writing of closure (-R and -Ra switches)
9918 to Binde; that's more convenient.
9920 2017-01-13 Ed Schonberg <schonberg@adacore.com>
9922 * sem_ch6.adb (Analyze_Expression_Function): If the expression
9923 function is a completion, all entities referenced in the
9924 expression are frozen. As a consequence, a reference to an
9925 uncompleted private type from an enclosing scope is illegal.
9927 2017-01-13 Javier Miranda <miranda@adacore.com>
9929 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
9930 (Analyze_Subprogram_Body_Helper): At the occurrence of an
9931 expression function declaration that is a completion, its
9932 expression causes freezing (AI12-0103).
9934 2017-01-13 Vadim Godunko <godunko@adacore.com>
9936 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

9955 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
9956 the legality of An others clause applies as well to a choice in
9957 an Iterated_component_ association.
9958 (Resolve_Iterated_Component_Association): An others choice
9960 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An

9992 Iterated_Component_Association: loop variable has the identifier
9993 of the original association. Generate a loop even for a single
9994 component choice, in order to make loop parameter visible in
9996 (Flatten): An Iterated_Component_Association is not static.
9998 2017-01-13 Yannick Moy <moy@adacore.com>
10000 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
10001 float exponentiation for statically known small negative values
10002 is the reciprocal of the exponentiation for the opposite value

10017 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10019 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
10020 mode a choice that is a subtype with a static predicate is
10021 replaced by the values it covers. This transformation must not
10022 be performed in ASIS mode, to preserve the source for analysis.

10038 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
10039 and resolve the discrete choices and the expression of the
10041 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
10042 Loop_Actions and Box_Present are attributes of
10043 N_Iterated_Component_Association nodes. Box_Present is always
10044 False in this case.
10045 * sprint.adb (Sprint_Node): An Iterated_Component_Association
10046 has a Discrete_Choices list, as specified in the RM. A
10047 Component_Association for aggregate uses instead a Choices list.

10049 construct also has a defining identifier, and there is no way
10050 to merge the two node structures.

10062 Analyze_Declarations, to analyze and resolve the expressions of
10063 aspect specifications in the current declarative list, so that
10064 the expressions have proper entity and type info. This is needed
10065 for ASIS when there is no subsequent expansion to generate this
10066 semantic information.
10067 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
10068 original expression, to suppress cascaded errors when expression
10069 has been constant-folded.
10070 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
10071 ASIS mode, because there is no subsequent expansion to decorate

10077 New function to detect when a call may be inlined or not in
10079 (Expand_Inlined_Call): Ensure that a temporary
10080 is always created in the cases where a type conversion may be
10081 needed on an input parameter in GNATprove mode, so that GNATprove
10082 sees the check to perform.
10083 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
10084 when not applicable due to actual requiring type conversion
10085 with possible check but no temporary value can be copied for
10086 GNATprove to see the check.
