3 * gcc-interface/gigi.h (pad_type_has_rm_size): Declare.
4 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Do not build
5 a padding type for the alignment before validating the size.
6 Flip conditional construct and add a comment.
7 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Size>: Make sure to
8 apply the exception for padded objects to the type of the object.
9 * gcc-interface/utils.c (hash_pad_type): New static function.
10 (lookup_and_insert_pad_type): Rename into...
11 (canonicalize_pad_type): ...this. Call hash_pad_type, do only one
12 lookup with insertion and always return the canonical type.
13 (maybe_pad_type): Adjust to above changes. Set debug type later.
14 (pad_type_has_rm_size): New predicate.
15 (set_reverse_storage_order_on_pad_type): Adjust to above changes.

62 2017-12-05 Jerome Lambourg <lambourg@adacore.com>
64 * libgnarl/s-taprop__qnx.adb: Better detect priority ceiling bug in
65 QNX. At startup, the first mutex created has a non-zero ceiling
66 priority whatever its actual policy. This makes some tests fail
67 (c940013 for example).
69 2017-12-05 Bob Duff <duff@adacore.com>
71 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Call
72 Expand_Cleanup_Actions for N_Extended_Return_Statement.
73 * exp_ch7.adb (Expand_Cleanup_Actions): Handle
74 N_Extended_Return_Statement by transforming the statements into a
75 block, and (indirectly) calling Expand_Cleanup_Actions on the block.
76 It's too hard for Expand_Cleanup_Actions to operate directly on the
77 N_Extended_Return_Statement, because it has a different structure than
78 the other node kinds that Expand_Cleanup_Actions.
79 * exp_util.adb (Requires_Cleanup_Actions): Add support for
80 N_Extended_Return_Statement. Change "when others => return False;" to
81 "when others => raise ...;" so it's clear what nodes this function
82 handles. Use named notation where appropriate.
83 * exp_util.ads: Mark incorrect comment with ???.
85 2017-12-05 Javier Miranda <miranda@adacore.com>

113 * sem_ch4.adb (Is_Private_Overriding): If the candidate private
114 subprogram is overloaded, scan the list of homonyms in the same
115 scope, to find the inherited operation that may be overridden
117 * exp_ch11.adb, exp_ch7.adb: Minor reformatting.
119 2017-12-05 Bob Duff <duff@adacore.com>
121 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
122 Init_Assignment is rewritten, we need to set Assignment_OK on the new
123 node. Otherwise, we will get spurious errors when initializing via
124 assignment statement.
126 2017-12-05 Hristian Kirtchev <kirtchev@adacore.com>

138 2017-12-05 Nicolas Setton <setton@adacore.com>
140 * terminals.c (__gnat_setup_child_communication): As documented,
141 __gnat_setup_child_communication should not terminate - it is intended
142 to be used as the child process of a call to fork(). However, execvp
143 might actually return in some cases, for instance when attempting to
144 run a 32-bit binary on a 64-bit Linux distribution when the
145 compatibility packages are not installed. In these cases, exit the
146 program to conform to the documentation.
148 2017-12-05 Olivier Hainque <hainque@adacore.com>

240 (Is_Potential_Scenario): Stop the traversal of a task body when
241 reaching an accept or select statement, and debug switch d_a is in

313 * tracebak.c (ppc64-vx7): USE_GCC_UNWINDER for 64bit.
315 2017-12-05 Javier Miranda <miranda@adacore.com>
317 * checks.adb (Generate_Range_Check): Force evaluation of the node in
318 more cases. This patch was written to improve the code generated by

334 * exp_aggr.adb (Gen_Assign): Do not analyze the expressionn of the
335 assignment if it is part of an Iterated_Component_Association: the
336 analysis needs to take place once the loop structure is analyzed and
337 the loop parameter made visible, because references to it typically
338 appear in the corresponding expression. This is necessary if the
339 expression is an aggregate, because previous pre-analysis of the
340 expression does not handle nested aggregates properly.
342 2017-12-05 Bob Duff <duff@adacore.com>
344 * sem_res.adb (Resolve_Allocator): Avoid coextension processing for an

362 Do not alter the module Low and High (relative) addresses.
363 (Is_Inside): Improve documentation regarding the kinds of addresses
364 at hand and correct the test.
365 (Symbolic_Traceback): Use separate variables with explicit names
366 for the address in traceback (run-time value) and the address to

373 * exp_ch4.adb (Expand_Nonbinary_Modular_Op): Use
374 Expand_Nonbinary_Modular_Ops instead of Modify_Tree_For_C, so that
375 other back-ends can also benefit from the front-end expansion. Remove
376 test for Modify_Tree_For_C in all callers to better share code.
377 * gnat1drv.adb (Adjust_Global_Switches): Set
378 Expand_Nonbinary_Modular_Ops when generating C code.

393 * exp_ch6.adb (Build_In_Place_Formal): Search for the formal by suffix
394 instead of the full name.
395 * sem_ch6.adb (Create_Extra_Formals): Make sure there are extra formals
396 in the case of an instance of a generic.
398 2017-12-05 Arnaud Charlet <charlet@adacore.com>
400 (Adjust_Global_Switches): Create an alias GNAT_Annotate to map to

875 * libgnarl/s-taprop__mingw.adb: On Windows, initialize the thead handle
876 only for foreign threads. We initialize the thread handle only if not

917 * libgnarl/s-taprop__qnx.adb: New, derived from s-taprop__posix.adb. This brings

920 also fixes the scheduling of FIFO tasks when the priority of a task is
922 * libgnat/system-qnx-aarch64.ads: Fix priority ranges.

931 as knowledge that Hex(2) is in the range 0..255 is too complex for
933 (Finalize): Add assumption for static analysis, as the fact that there
934 are symbols in the table depends on a global invariant at this point in
936 * set_targ.adb (Check_Spaces): Justify CodePeer false positive message.

981 * freeze.adb (Check_Component_Storage_Order): Default initialize
982 Comp_Byte_Aligned rather than silencing messages with pragma
983 Warnings(Off), which does not work for CodePeer initialization
984 messages, and given that here the possible read of an unitialized value
985 depends on a proper use of parameters by the caller.
986 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.

996 * sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,
997 and restructure code to defend against previous errors, so that, in

1004 precisely. This requires to exchange the test for exiting in case of
1005 too many positions and the increment to Position, inside the loop.

1007 which cannot be read uninitialized, but the reasons for that are quite

1012 * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
1013 and test for presence of non-null Opnd_Type before testing its scope,
1014 in a test which would read its value uninitialized, and is very rarely

2450 * sem_ch4.adb (Try_Class_Wide_Operation, Traverse_Homonyms):
2451 Suppress spurious ambiguity error when two traversals of the homonym
2452 chain (first directly, and then through an examination of relevant
2453 interfaces) retrieve the same operation, when other irrelevant homonyms
2454 of the operatioh are also present.
2456 2017-10-09 Ed Schonberg <schonberg@adacore.com>
2458 * sem_util.adb (Object_Access_Level): If the object is the return
2459 statement of an expression function, return the level of the function.
2460 This is relevant when the object involves an implicit conversion
2461 between access types and the expression function is a completion, which
2462 forces the analysis of the expression before rewriting it as a body, so
2463 that freeze nodes can appear in the proper scope.
2465 2017-10-09 Bob Duff <duff@adacore.com>
2467 * atree.adb: Make nnd apply to everything "interesting", including
2468 Rewrite. Remove rrd.

2472 * exp_ch3.adb (Expand_N_Object_Declaration): Avoid never-ending loop
2473 processing the declaration of the dummy object internally created by
2474 Make_DT to compute the offset to the top of components referencing
2475 secondary dispatch tables.
2476 (Initialize_Tag): Do not initialize the offset-to-top field if it has
2477 been initialized initialized.
2478 * exp_disp.ads (Building_Static_Secondary_DT): New subprogram.
2479 * exp_disp.adb (Building_Static_Secondary_DT): New subprogram.
2480 (Make_DT): Create a dummy constant object if we can statically build
2481 secondary dispatch tables.
2482 (Make_Secondary_DT): For statically allocated secondary dispatch tables
2483 use the dummy object to compute the offset-to-top field value by means
2484 of the attribute 'Position.
2486 2017-10-09 Bob Duff <duff@adacore.com>
2488 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking
2489 code so if BIPAlloc is not passed in, it will likely raise
2490 Program_Error instead of cause miscellaneous chaos.
2491 (Is_Build_In_Place_Result_Type): Return False if not Expander_Active,
2492 as for the other Is_B-I-P... functions.
2493 * sem_aggr.adb (Resolve_Extension_Aggregate): For an extension
2494 aggregate whose ancestor part is a build-in-place call returning a
2495 nonlimited type, transform the assignment to the ancestor part to use a
2497 * sem_ch3.adb (Build_Itype_Reference): Handle the case where we're
2498 creating an Itype for a library unit entity.
2499 (Check_Initialization): Avoid spurious error message on
2500 internally-generated call.
2501 * sem_ch5.adb (Analyze_Assignment): Handle the case where the
2502 right-hand side is a build-in-place call. This didn't happen when b-i-p
2503 was only for limited types.
2504 * sem_ch6.adb (Create_Extra_Formals): Remove assumption that b-i-p
2505 implies >= Ada 2005.
2506 * sem_ch7.adb (Scan_Subprogram_Refs): Avoid traversing the same nodes
2508 * sem_util.adb (Next_Actual): Handle case of build-in-place call.

2534 actual for a formal package is an instantiation of a child unit, create
2535 a freeze node for the instance of the parent if it appears in the same
2536 scope and is not frozen yet.
2538 2017-10-09 Pierre-Marie de Rodat <derodat@adacore.com>
2540 * exp_atag.ads, libgnat/a-tags.adb, libgnat/a-tags.ads: Enhance

2543 2017-10-09 Bob Duff <duff@adacore.com>
2545 * exp_ch3.adb (Build_Assignment): Parameter name N was somewhat
2546 confusing. Same for N_Loc. Remove assumption that b-i-p implies
2547 limited. This is for the case of a function call that occurs as the
2548 default for a record component.
2549 (Expand_N_Object_Declaration): Deal with the case where expansion has
2550 created an object declaration initialized with something like
2552 * exp_ch3.adb: Minor reformatting.
2554 2017-10-09 Ed Schonberg <schonberg@adacore.com>
2556 * exp_attr.adb (Expand_Attribute_Reference, case 'Valid): The prefix of
2557 the attribute is an object, but it may appear within a conversion. The
2558 object itself must be retrieved when generating the range test that
2559 implements the validity check on a scalar type.
2561 2017-10-05 Eric Botcazou <ebotcazou@adacore.com>

2573 (timeval): Use suseconds_t for tv_usec.
2574 * libgnarl/s-osinte__x32.adb (To_Timespec): Remove use type clause.

2578 * gcc-interface/decl.c (annotate_value): Use wi::to_widest when
2579 handling the form (plus/mult (convert @0) @1).
2581 2017-09-29 Bob Duff <duff@adacore.com>
2583 * exp_ch6.adb (Expand_Call_Helper): Replace with code more similar to
2585 (Make_Build_In_Place_Call_In_Object_Declaration): Back out previous
2586 change. Set the Etype in the class-wide case. This fixes a regression
2587 in the libadalang test suite.
2589 2017-09-29 Joel Brobecker <brobecker@adacore.com>
2591 * doc/gnat_ugn/building_executable_programs_with_gnat.rst,

2605 uninitialized file descriptors.
2606 * osint.adb, osint.ads (Read_Source_File): Add extra parameter to

2614 and type conversions.
2615 (Expand_N_Extended_Return_Statement): Correct the computation of

2617 (Expand_Simple_Function_Return): Remove assumption that b-i-p implies

2620 (Is_Build_In_Place_Result_Type): New function to accompany
2621 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
2622 sometimes we just have the type on our hands, not the function. For
2623 now, does the same thing as the old version, so build-in-place is
2624 disabled for nonlimited types, except that you can use -gnatd.9 to
2626 * exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
2627 accompany Is_Build_In_Place_Function and
2628 Is_Build_In_Place_Function_Call, because sometimes we just have the
2629 type on our hands, not the function.
2630 (Make_Build_In_Place_Call_In_...): Handle nonlimited build-in-place
2632 (Make_Build_In_Place_Call_In_Object_Declaration): Remove the
2633 questionable code at the end that was setting the Etype.
2634 * exp_aggr.adb (Is_Build_In_Place_Aggregate_Return): New function to
2635 determine whether "return (...agg...);" is returning from a
2636 build-in-place function.

2638 Remove assumption that b-i-p implies limited (initialization of
2639 In_Place_Expansion).
2640 (Build_Record_Aggr_Code): AI-287: fix comment; it can't be wrapped in
2641 an unchecked conversion. Add assertions.
2642 (Convert_Aggr_In_Object_Decl): Establish_Transient_Scope -- no need for
2643 secondary stack here, just because the type needs finalization. That
2645 (Convert_To_Assignments): Only set Unc_Decl if Nkind (N) = N_Aggregate.
2646 For "return (...agg...);" don't assume b-i-p implies limited.

2665 b-i-p implies >= Ada 2005.
2666 * exp_util.adb (Build_Allocate_Deallocate_Proc): Look at Storage_Pool
2667 (Expr), in case Pool_Id is not set.
2668 (Initialized_By_Aliased_BIP_Func_Call): Handle case where the call is
2669 qualified or converted.
2670 (Is_Secondary_Stack_BIP_Func_Call): Don't check if Nkind (Selector_Name
2671 (Param)) = N_Identifier; that's all it could be.
2672 * sinfo.ads: Comment fixes.
2673 * snames.ads-tmpl: Comment fixes.

2704 2017-09-29 Ed Schonberg <schonberg@adacore.com>
2706 * sem_ch6.adb (Analyze_Expression_Function): Do not emit freeze nodes
2707 for types in expression if the function is within a generic unit.
2708 * sem_res.adb (Resolve): In a generic context do not freeze an
2709 expression, unless it is an entity. This exception is solely for the
2710 purpose of detecting illegal uses of deferred constants in generic

2783 (Use_One_Package, Use_One_Type): Major cleanup and reorganization to
2784 handle the new chaining algorithm, also many changes related to
2785 redundant clauses. A new parameter has also been added to force
2786 installation to handle certain cases.

3654 to libgnat subdirectory.
3656 2017-09-08 Yannick Moy <moy@adacore.com>
3658 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
3659 return the entity associated with the call.
3660 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
3661 Replace the internal Get_Function_Id with the new
3662 Sem_Aux.Get_Called_Entity.
3663 (Iterate_Call_Parameters): New
3664 procedure to iterate on formals and actuals at the same time.
3665 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
3666 Set SPARK_Mode from spec when set, for analysis
3667 of instance. Restore after analysis of instance.
3668 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
3669 set, for analysis of body instance. Restored automatically at
3670 the end of the subprogram.
3671 * gnat1drv.adb (Adjust_Global_Switches): Set
3672 Check_Validity_Of_Parameters to False in GNATprove mode.
3673 * opt.ads (Check_Validity_Of_Parameters): Document switch to
3676 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3678 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
3679 (New_Copy_Tree): ...there. Reset the hash tables only if they
3680 were used in the previous invocation.
3681 * s-htable.adb: Fix typo.
3683 2017-09-08 Bob Duff <duff@adacore.com>
3685 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
3687 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3689 * sem_aggr.adb: minor style fix.
3691 2017-09-08 Bob Duff <duff@adacore.com>
3693 * sprint.adb (Write_Corresponding_Source): Ignore if there is
3694 no current source file.
3695 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
3696 Print something helpful in case N is invalid.
3697 * sprint.ads: Minor comment fix.
3699 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3701 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
3704 2017-09-08 Bob Duff <duff@adacore.com>
3706 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
3707 Ada_2020, along the same lines as the other Ada version pragmas.
3709 2017-09-08 Gary Dismukes <dismukes@adacore.com>
3711 * sem_ch12.adb: Minor typo fixes and reformatting.
3713 2017-09-08 Yannick Moy <moy@adacore.com>
3715 * sem_aggr.adb (Resolve_Record_Aggregate):
3716 Rewrite bounds of aggregate subexpressions which may depend on
3717 discriminants of the enclosing aggregate.
3719 2017-09-08 Yannick Moy <moy@adacore.com>
3721 * sem_ch5.adb: Prevent assertion failure on illegal code.
3723 2017-09-08 Yannick Moy <moy@adacore.com>
3725 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
3726 calling Renamed_Entity on an entity which cannot be a renaming.
3728 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3730 * exp_aggr.adb: Add with & use clause for Urealp.
3731 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
3732 elementary types instead of just discrete types.
3733 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
3734 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
3735 Be prepared for the FP zero value in the memset case. Add small
3738 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3740 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
3743 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3745 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
3746 of New_Copy because the latter leaves the syntactic structure of
3747 the tree inconsistent (a child is accessible through two parents)
3748 and prevents proper replication of itypes by subsequent calls
3750 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
3751 New_Copy because the latter leaves the syntactic structure of the
3752 tree inconsistent (a child is accessible through two parents)
3753 and prevents proper replication of itypes by subsequent calls
3755 * sem_util.adb (In_Subtree): New routine.
3756 (New_Copy_Tree): Reimplemented.

3762 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
3763 for aspect Default_Value is a static scalar value, but it does
3764 not freeze the type. Yhis allows for subsequent representation
3765 clauses for the type.
3767 2017-09-08 Javier Miranda <miranda@adacore.com>
3769 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
3770 not add entries into the undefined reference table when we are
3771 compiling with errors ignored.
3773 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3775 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
3776 check if the instance is within an enclosing instance body. The
3777 formal package was legal in the enclosing generic, and is
3778 legal in the enclosing instantiation. This optimisation may be
3779 applicable elsewhere, and it also removes spurious errors that
3780 may arise with on-the-fly processing of instantiations that
3781 contain Inline_Always subprograms.
3783 2017-09-08 Vincent Celier <celier@adacore.com>
3785 * gnatcmd.adb: Disregard empty argument of GNAT driver.
3787 2017-09-08 Justin Squirek <squirek@adacore.com>
3789 * checks.adb (Insert_Valid_Check): Manually decorate
3790 the generated temporary for range valdity checks.
3792 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3794 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
3796 2017-09-08 Justin Squirek <squirek@adacore.com>
3798 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
3799 case to handle underscore flags.
3800 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
3801 new procedure to handle underscores.
3803 2017-09-08 Javier Miranda <miranda@adacore.com>
3805 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
3806 divisions with fixed point results to avoid generating twice
3807 the runtime check on divide by zero.
3808 * checks.adb (Apply_Divide_Checks): Ensure that operands are
3809 not evaluated twice (once for their runtime checks and once for
3810 their regular computation).
3812 2017-09-08 Yannick Moy <moy@adacore.com>
3814 * sem_prag.adb (Analyze_Part_Of): Add missing
3815 return statements after issuing errors. Add detection of
3816 out-of-order item and single concurrent type.

3923 New routine to read the Tag robustly.
3924 * exp_attr.adb (Input): Change the expansion of 'Input,
3925 in the class-wide case, to call String_Input_Tag instead of
3926 String_Input_Blk_IO.
3928 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3930 * s-rident.ads (Restriction_Id): reorder enum
3931 literals, so that Pure_Barriers is no longer in range of the
3932 Cunit_Boolean_Restrictions subtype.
3934 2017-09-08 Nicolas Roche <roche@adacore.com>
3936 * a-taster.ads, a-taster.adb: Move to libgnarl

3946 when the actual is a construct that involves a dereference of an
3947 expression that includes a formal of the enclosing subprogram,
3948 In such cases, the accessibility level of the actual is that of
3949 the corresponding formal, which is passed in as an additional
3950 actual in the outer call.
3952 2017-09-08 Bob Duff <duff@adacore.com>
3954 * exp_intr.adb (Add_Source_Info): Do not decode

3957 2017-09-08 Bob Duff <duff@adacore.com>
3959 * a-tags.adb (Internal_Tag): Unsuppress checks, so we get
3960 exceptions instead of crashes. Check for absurdly long strings
3961 and empty strings. Empty strings cause trouble because they can
3962 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
3963 be empty, which causes an array index out of bounds.
3964 * s-ststop.adb (Input): Unsuppress checks, so we get exceptions
3967 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3969 * sem_util.adb (Is_CCT_Instance): allow use in
3970 the context of protected types.
3972 2017-09-08 Arnaud Charlet <charlet@adacore.com>

3989 not skip a loop coming from source which is rewritten into a loop.
3991 2017-09-08 Ed Schonberg <schonberg@adacore.com>

4024 * par-ch4.adb (P_Iterated_Component_Association): Place construct
4025 under -gnat2020 flag, given that it is a future feature of
4027 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
4028 defining identifier as referenced to prevent spurious warnings:
4029 corresponding loop is expanded into one or more loops whose
4030 variable has the same name, and the expression uses those names
4031 and not the original one.
4033 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4035 * sem_elab.adb (Check_A_Call): Do not consider
4036 references to internal variables for SPARK semantics.

4141 access to interface types. Remove also the accessibility check.
4143 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4145 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
4146 all the types that are referenced by the expression.
4147 (Analyze_Expression_Function): Call Freeze_Expr_Types for
4148 a completion instead of manually freezing the type of the
4150 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
4152 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4154 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
4155 New procedure, auxiliary to Expand_Pragma_Check, to handle
4156 references to the discriminants of a protected type within a
4157 precondition of a protected operation. This is needed because
4158 the original precondition has been analyzed in the context of
4159 the protected declaration, but in the body of the operation
4160 references to the discriminants have been replaved by references
4161 to the discriminants of the target object, and these references
4162 are only created when expanding the protected body.
4164 2017-09-08 Yannick Moy <moy@adacore.com>
4166 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
4169 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4171 * exp_attr.adb (Build_Record_VS_Func): If the record is an
4172 unchecked union, do not emit checks for its (non-existent)
4173 discriminants, or for variant parts that depend on them.

4177 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
4178 Find_Comparison_Type.Try_One_Interp): Add check for generic
4181 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4183 * sem_ch3.adb, layout.adb, layout.ads, exp_attr.adb, debug.adb,
4184 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
4185 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
4186 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
4187 remaining references to AAMP_On_Target.
4189 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4191 * style.adb: Fix typo.
4193 2017-09-08 Javier Miranda <miranda@adacore.com>
4195 * einfo.adb (Underlying_Type): Add missing support for class-wide
4196 types that come from the limited view.
4197 * exp_attr.adb (Attribute_Address): Check class-wide type

4200 (Attribute_Tag): Check class-wide type interfaces using
4201 the underlying type to handle limited-withed types.
4203 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4205 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
4206 over a subtype of a type with a static predicate, taking into
4207 account the predicate function of the parent type and the bounds
4208 given in the loop specification.
4209 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
4210 a loop specification that is a subtype indication whose type mark
4211 is a type with a static predicate, inherit predicate function,
4212 used to build case statement for rewritten loop.
4214 2017-09-08 Justin Squirek <squirek@adacore.com>
4216 * lib-load.adb: Modify printing of error message to exclude file
4219 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4221 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
4222 don't inline subprograms declared in both visible and private
4224 (In_Package_Spec): previously In_Package_Visible_Spec; now
4225 detects subprograms declared both in visible and private parts
4228 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4230 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
4231 the type is an anonymous array in an object declaration, whose
4232 component type has an invariant, use the object declaration
4233 as the insertion point for the invariant procedure, given that
4234 there is no explicit type declaration for an anonymous array type.
4236 2017-09-08 Bob Duff <duff@adacore.com>
4238 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.

4253 Default_WCEM by default (i.e. if the encoding is not specified
4254 by the Form string).
4256 2017-09-08 Bob Duff <duff@adacore.com>
4258 * s-trasym.ads (Hexa_Traceback): If
4259 Suppress_Hex is True, print "..." instead of a hexadecimal
4261 * s-trasym.adb: Ignore No_Hex in this version.
4264 2017-09-08 Bob Duff <duff@adacore.com>
4266 * debug.adb: Minor reformatting.
4268 2017-09-08 Bob Duff <duff@adacore.com>
4270 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
4271 code so it doesn't trigger an "uninit var" warning.
4273 2017-09-08 Nicolas Roche <roche@adacore.com>
4275 * s-hibaen.ads: Remove obsolete file.
4277 2017-09-08 Arnaud Charlet <charlet@adacore.com>

4289 2017-09-08 Bob Duff <duff@adacore.com>
4291 * checks.adb (Insert_Valid_Check): Copy the Do_Range_Check flag to the
4294 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4296 * debug.adb (dA): Adjust comment.
4297 * gnat1drv.adb (Gnat1drv): Likewise.
4298 * opt.ads (List_Representation_Info_Extended): New variable.
4299 * repinfo.adb (List_Record_Info): Split implementation into...
4300 (Compute_Max_Length): ...this. Recurse on records if requested.
4301 (List_Record_Layout): Likewise.
4302 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
4303 statement, accept '0' and set List_Representation_Info_Extended
4305 * usage.adb (Usage): Document new -gnatRe variant.
4307 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4309 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
4310 Do not save the given entity in the global variable Default_Pool
4311 if the pragma appears within a generic unit.
4313 2017-09-08 Bob Duff <duff@adacore.com>
4315 * errout.adb (Delete_Warning): Do not
4316 decrement Warnings_Treated_As_Errors. This is called before
4317 Warnings_Treated_As_Errors has been incremented to account for
4318 this warning. Decrementing it here can lead to negative values
4319 of Warnings_Treated_As_Errors, raising Constraint_Error in
4320 checks-on builds, and causing the compiler to return an error
4321 code in checks-off builds.
4323 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4325 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
4326 entities of named concurrent types as Ref_Id and not of anonymous
4327 concurrent objects (because callers already know when a conversion
4328 is necessary and can easily do it); also, do not expect protected
4329 types or protected objects as Context_Id (because no flow-related
4330 SPARK pragmas are attached there); reflect these changes in a
4331 more precise comment.
4333 2017-09-08 Olivier Hainque <hainque@adacore.com>
4335 * g-altive.ads: Add documentation.
4337 2017-09-08 Bob Duff <duff@adacore.com>
4339 * sem_util.ads, debug.adb: Minor comment fix.
4340 * erroutc.ads: Comment fix.
4342 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4344 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
4345 for compatibility of component types of formal and actual in an
4346 instantiation of a child unit, when the component type of the
4347 formal is itself a formal of an enclosing generic.
4349 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4351 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
4352 sem_prag.adb to make it available for GNATprove; for concurrent
4353 types replace custom scope climbing with Scope_Same_Or_Within; for
4354 single concurrent objects add scope climbing (with Scope_Within),
4355 which was not there (that's the primary semantic change of this
4356 commit); also, when comparing a single concurrent object with
4357 its corresponding concurrent type rely on equality of types,
4358 not of objects (because that's simpler to code).
4359 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
4360 (Analyze_Global_Item): adjust special-casing of references to the
4361 current instance of a concurrent unit in the Global contracts
4362 of task types and single tasks objects; similar for references
4363 in the protected operations and entries of protected types and
4364 single protected objects (in all these cases the current instance
4365 behaves as an implicit parameter and must not be mentioned in
4366 the Global contract).
4368 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4370 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
4371 function calls returning a record within a subprogram call,
4374 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4376 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
4377 name that designates the current instance of a child unit in its
4378 own body and appears as the prefix of a reference to an entity
4379 local to the child unit.
4380 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
4383 2017-09-08 Yannick Moy <moy@adacore.com>
4385 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that

4390 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
4391 warnings on internal units in configurable run time mode.
4393 2017-09-08 Bob Duff <duff@adacore.com>
4395 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
4396 representation items from interfaces that the derived type
4397 implements, not just from the parent type.
4398 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
4399 this to return an empty list when there are no interfaces.
4400 * einfo.ads, sem_ch13.adb: Minor comment fixes.
4401 * sem_attr.adb: Minor comment fix.
4403 2017-09-08 Doug Rupp <rupp@adacore.com>

4408 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4410 * exp_ch4.adb (Expand_N_Allocator): Generate a
4411 call to Allocate_Any_Controlled when the allocation does not
4412 require any initialization.
4414 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>

4939 reference to SPARK RM.
4941 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4943 * layout.adb: Use SSU short hand consistently throughout the file.
4945 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4947 * freeze.adb (Freeze_Record_Type)
4948 <Sized_Component_Total_Round_RM_Size>: New local variable to
4949 accumulate the rounded RM_Size of components. Update it for
4950 every component whose RM_Size is statically known. Add missing
4951 guard to check that bit packing is really required before issuing
4952 the error about packing. Swap condition for clarity's sake.
4953 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.
4955 2017-09-06 Fedor Rybin <frybin@adacore.com>
4957 * makeutl.adb, makeutl.ads, mlib.adb, mlib.ads, mlib-fil.adb,

4972 project manager sources.
4974 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4976 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
4977 entity of a mutable type and the right-hand side is a conditional
4978 expression, resolve the alternatives of the conditional using
4979 the base type of the target entity, because the alternatives
4980 may have distinct subtypes. This is particularly relevant if
4981 the alternatives are aggregates.
4983 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4985 * checks.adb (Apply_Predicate_Check): If the expression is an
4986 aggregate that is the RHS of an assignment, apply the check to
4987 the LHS after the assignment, rather than to the aggregate. This
4988 is more efficient than creating a temporary for the aggregate,
4989 and prevents back-end crashes when the aggregate includes a
4990 dynamic "others' association.
4992 2017-09-06 Yannick Moy <moy@adacore.com>
4994 * sem_ch12.adb (Analyze_Instance_And_Renamings):
4995 Set variable to ignore SPARK_Mode in instance before the analysis
4996 of the generated package declaration.
4998 2017-09-06 Yannick Moy <moy@adacore.com>
5000 * sem_res.adb (Resolve_Call): Do not issue a
5001 message for calls inside expression function, unless body was
5002 seen and is candidate for inlining.
5004 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5006 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.
5007 * sem_ch3.adb (Analyze_Declarations): In a generic subprogram
5008 body. do not freeze the formals of the generic unit.
5010 2017-09-06 Gary Dismukes <dismukes@adacore.com>
5012 * errout.adb (Error_Msg): Separate the
5013 treatment for warning vs. style messages in inlinings and
5014 instantiations. Prevents blowups on calls to Warn_Insertion for
5015 style messages, which should not be called in that case because
5016 Warning_Msg_Char is not set.
5018 2017-09-06 Justin Squirek <squirek@adacore.com>
5020 * sem_prag.adb (Check_VFA_Conflicts): Created
5021 to group all Volatile_Full_Access checks relating to other
5022 representation pragmas (Mark_Component_Or_Object): Created
5023 to centeralize the flagging of attributes for the record type
5024 component case, a pragma applied individually to a component, and
5026 (Process_Atomic_Independent_Shared_Volatile):
5027 Add propagation of certain pragmas to record components and move
5028 evaluation of VFA checks
5030 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5032 * sem_prag.adb (Check_Postcondition_Use_In_Inlined_Subprogram):
5033 Do not warn on conditions that are not obeyed for Inline_Always
5034 subprograms, when assertions are not enabled.
5036 2017-09-06 Arnaud Charlet <charlet@adacore.com>
5038 * sem_util.adb (Unique_Entity): For abstract states return their
5041 2017-09-06 Bob Duff <duff@adacore.com>
5043 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
5044 that is a proper body corresponding to a stub, we defer the
5045 adjustment of the sloc until after the correct adjustment has
5046 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
5047 the adjustment, because it will be outside the range in (the old,
5048 incorrect) S_Adjustment.
5049 * inline.adb: Use named notation for readability and uniformity.
5050 * sinput-l.adb: Minor improvements to debugging output printed
5052 * sinput-l.ads (Create_Instantiation_Source): Minor comment
5055 2017-09-06 Vincent Celier <celier@adacore.com>
5057 * make.adb: Do not invoke gprbuild for -bargs -P.
5059 2017-09-06 Sylvain Dailler <dailler@adacore.com>
5061 * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a
5062 case when Op is of kind N_Qualified_Expression. In this case,
5063 the function is called recursively on the subexpression like in
5065 * make.adb: Minor reformatting
5067 2017-09-06 Justin Squirek <squirek@adacore.com>
5069 * einfo.adb (Set_Linker_Section_Pragma): Modify
5070 Set_Linker_Section_Pragma to be consistant with the "getter"
5071 Linker_Section_Pragma.
5072 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
5073 checking for container loops so that the index cursor is not
5074 directly changable by the user with the use of E_Loop_Parameter.
5075 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.
5076 * sem_warn.adb (Check_References): Revert previous change.
5078 2017-09-06 Bob Duff <duff@adacore.com>

5086 declarations to only consider valid uses of Global/Depends those on
5087 single concurrent objects.

5109 make_util.ads, sinput.adb, sinput.ads, clean.adb, gnatls.adb,
5110 gnatname.adb: Remove the Project Manager from the GNAT tools.
5111 * gcc-interface/Makefile.in: ditto.
5113 2017-09-06 Bob Duff <duff@adacore.com>
5115 * sem_util.ads: Minor comment fix.
5117 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5119 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
5120 Generate a freeze node for the actual of a formal package, if
5121 the actual is declared in the same unit and has a corresponding
5122 body, to prevent the current instance from being frozen before
5125 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
5127 * sem_ch7.adb (Entity_Table_Size): Change to nearest prime number.

5144 * exp_util.adb (Is_Controlled_Indexing): New routine.
5145 (Is_Displace_Call): Use routine Strip to remove indirections.
5146 (Is_Displacement_Of_Object_Or_Function_Result): Code clean up. Add a
5147 missing case of controlled generalized indexing.
5148 (Is_Source_Object): Use routine Strip to remove indirections.
5149 (Strip): New routine.
5151 2017-09-06 Bob Duff <duff@adacore.com>
5153 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
5154 we include the proper header. Otherwise, we just declare the necessary
5155 things from the capabilities library. This is so we can build on
5156 machines without that library, while still enabling that library.
5157 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
5158 simply return 0 if the library is not present, or not included
5161 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
5163 * exp_dbug.adb (Debug_Renaming_Declaration): Do not create an encoding

5174 has no parameter specification and no entry index, use the entry name
5175 as the end of the generated SCO statement.
5177 2017-09-06 Steve Baird <baird@adacore.com>
5179 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
5180 uses of 'Image and related attributes as having side effects in
5181 order to avoid replicating such uses.
5182 * pprint.ads (Expression_Image) Add new generic formal flag
5183 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
5184 (eventually) override the default.
5185 * pprint.adb (Expression_Image) If the new flag is set, then
5186 suppress the ".all" suffix when displaying a dereference whose
5187 prefix is a use of a value-capturing compiler temp of the sort
5188 generated by Expr_Util.Remove_Side_Effects .
5189 * exp_attr.adb, g-catiio.adb, inline.adb, sem_attr.adb, sem_ch13.adb,

5202 * sem_util.adb, sem_util.ads (Within_Protected_Type): Renaming
5203 with slight modification from Is_Subp_Or_Entry_Inside_Protected,
5204 so that applies to any entity.
5206 2017-09-06 Yannick Moy <moy@adacore.com>
5208 * sem_ch3.adb (Derived_Type_Declaration): Use
5209 Incomplete_Or_Partial_View rather than local Find_Partial_View.
5211 2017-09-06 Javier Miranda <miranda@adacore.com>
5213 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
5216 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5218 * sem_dim.adb (Analyze_Dimension): In an instance, a type
5219 conversion takes its dimensions from the expression, not from
5221 (Dimensions_Of_Operand): Ditto.
5223 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5225 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to
5226 null procedures when GNAT coverage is used, so that their (empty)
5227 bodies are properly covered.
5229 2017-09-06 Bob Duff <duff@adacore.com>
5231 * sem_ch13.adb (Resolve_Aspect_Expressions): If
5232 the entity is a type with discriminants, make the discriminants

5237 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are
5238 Universal_Real and the context is a floating-point type, resolve
5239 both operands to the target type.
5241 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
5243 * a-comlin.adb, exp_aggr.adb, exp_ch6.adb, frontend.adb, gnatbind.adb,

5246 2017-09-06 Yannick Moy <moy@adacore.com>
5248 * freeze.adb (Check_Inherited_Conditions): Rewriting
5249 of inherited preconditions and postconditions should only occur
5250 in GNATprove mode, that is, when GNATprove_Mode is True, not to
5251 be confused with SPARK_Mode being On.
5253 2017-09-06 Yannick Moy <moy@adacore.com>

5266 on the procedure created to encapsulate the body.
5267 * sem_ch7.adb: Add with clause for GNAT.HTable.
5268 (Entity_Table_Size): New constant.
5269 (Entity_Hash): New function.
5270 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
5271 (Is_Subprogram_Ref): Rename into...
5272 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
5273 the table instead of bailing out on them. Scan the value of constants
5274 if it is not known at compile time.
5275 (Contains_Subprograms_Refs): Rename into...
5276 (Scan_Subprogram_Refs): ...this.
5277 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
5278 Is_Public flag on subprograms if they are not actually referenced.
5279 (Hide_Public_Entities): Beef up comment on the algorithm.
5280 Reset the table of subprograms on entry.
5282 2017-09-06 Yannick Moy <moy@adacore.com>

5323 of protected subprograms and entries.
5324 * sem_util.adb, sem_util.ads (Is_Subp_Or_Entry_Inside_Protected):
5325 New function to detect when a subprogram of entry is defined

5336 2017-09-06 Bob Duff <duff@adacore.com>
5338 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint
5339 check back to the body, because SPARK is not yet ready for
5340 "or else raise Constraint_Error".

5365 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5367 * sem_type.adb (Interface_Present_In_Ancestor): Within an
5368 expression function, or within a spec expression (default value,
5369 etc) a reference to an incomplete type is legal: legality of
5370 the operation will be checked when some related entity (type,
5371 object or subprogram) is frozen.
5373 2017-09-06 Gary Dismukes <dismukes@adacore.com>
5375 * exp_ch5.adb, s-diinio.ads, sem_ch4.adb, s-diflio.ads: Minor spelling

5386 * a-comlin.ads, a-comlin.adb (Argument): Simplify the code, now that
5387 we can use modern Ada in this package.
5388 * s-resfil.ads, s-resfil.adb, a-clrefi.ads, a-clrefi.adb:
5389 Move Ada.Command_Line.Response_File to System.Response_File,
5390 and make Ada.Command_Line.Response_File into a rename of
5391 System.Response_File. This is to avoid having gnatbind depend
5392 Ada.Command_Line, which would damage the bootstrap process now
5393 that Ada.Command_Line contains modern Ada (the raise expression).
5394 * gnatbind.adb: Avoid dependence on
5395 Ada.Command_Line. Depend on System.Response_File instead
5396 of Ada.Command_Line.Response_File. Change one call to
5397 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
5398 to Ada.Command_Line.Argument_Count to use Arg_Count.
5399 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
5401 2017-09-06 Bob Duff <duff@adacore.com>
5403 * frontend.adb (Frontend): Skip -gnatec=gnat.adc

5408 * exp_ch5.adb (Get_Default_Iterator): Replace
5409 "Assert(False)" with "return Iter", because if an iterable

5411 overriding or inherited default iterator.
5413 2017-09-06 Yannick Moy <moy@adacore.com>
5415 * sem_warn.adb (Warn_On_Suspicious_Index): Improve warning when the
5416 literal index used to access a string is null or negative.
5418 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>

5421 allowed on loop parameters.
5422 (Set_Status_Flag_Or_Transient_Decl): The attribute is now allowed
5424 (Write_Field15_Name): Update the output for
5425 Status_Flag_Or_Transient_Decl.
5426 * einfo.ads: Attribute Status_Flag_Or_Transient_Decl now applies
5427 to loop parameters. Update the documentation of the attribute
5428 and the E_Loop_Parameter entity.
5429 * exp_ch7.adb (Process_Declarations): Remove the bogus guard
5430 which assumes that cursors can never be controlled.

5538 not retrievable as selected components.
5540 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5542 * sem_util.adb (Needs_One_Formal): The first formal of such a

5582 not visible in the object.
5583 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
5584 side may be derived from that of the left-hand side (as in the
5585 case of an assignment with a change of representation) so the
5586 discriminant to be used in the retrieval of the value of the
5587 component must be the entity in the type of the right-hand side.

6162 * exp_ch6.adb (Expand_Call_Helper): When locating the
6163 accessibility entity created for an access parameter, handle
6164 properly a reference to a formal of an enclosing subprogram. if
6165 the reference appears in an inherited class-wide condition, it
6166 is the rewriting of the reference in the ancestor expression,
6167 but the accessibility entity must be that of the current formal.
6169 2017-05-02 Javier Miranda <miranda@adacore.com>
6171 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.
6172 (Expand_N_Op_Add, Expand_N_Op_Divide, Expand_N_Op_Minus,

6206 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
6207 procedure body for a local (sub)type declaration within a
6208 predicate function. Invariant checks do not apply to these, and
6209 the expansion of the procedure will happen in the wrong scope,
6210 leading to misplaced freeze nodes.
6212 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6214 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
6215 to analyze generated actions. If the main unit is a body,

6218 2017-05-02 Arnaud Charlet <charlet@adacore.com>
6220 * einfo.adb (Declaration_Node): flip branches of
6221 an IF statement to avoid repeated negations in its condition;

6251 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
6252 Refine predicate for the case where the primitive operation
6253 is a renaming of equality. An overriding operation that is
6254 a user-defined renaming of predefined equality inherits its
6255 slot from the overridden operation. Otherwise it is treated
6256 as a predefined op and occupies the same predefined slot as
6257 equality. A call to it is transformed into a call to its alias,
6258 which is the predefined equality. A dispatching call thus uses
6259 the proper slot if operation is further inherited and called
6260 with class-wide arguments.
6262 2017-05-02 Justin Squirek <squirek@adacore.com>
6264 * errout.adb (Set_Msg_Text): Add a case to switch the message
6265 type when the character '[' is detected signifying a warning
6266 about a run-time exception.
6267 * opt.ads Add a new Warning_Mode value for new switch
6268 * switch-b.adb (Scan_Binder_Switches): Add case for the binder
6269 to handle new warning mode

6273 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6275 * sem_prag.adb (Process_Conversion): Reject an intrinsic operator
6276 declaration that operates on some fixed point type.

6297 * exp_ch3.adb (Build_Initialization_Call): Generate a null
6298 statement if the initialization call is a null procedure, as
6299 can happen with a controlled type with no explicit Initialize
6300 procedure, or an array of such.
6301 * exp_ch7.adb (Process_Object_Declaration): For a type with
6302 controlled components that has a trivial Initialize procedure,
6303 insert declaration for finalization counter after object
6305 (Make_Deep_Array_Body, Build_Initialize_statements): Do not create
6306 finalization block and attendant declarations if component has
6307 a trivial Initialize procedure.
6308 (Make_Init_Call): Do not generate a call if controlled type has
6309 a trivial Initialize procedure.

6339 2017-05-02 Gary Dismukes <dismukes@adacore.com>
6341 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
6342 parameter Array_Comp to indicate the case of an array object
6343 with null-excluding components.
6344 * checks.adb (Null_Exclusion_Static_Checks):
6345 Call Compile_Time_Constraint_Error instead of
6346 Apply_Compile_Time_Constraint_Error in the component case. Also
6347 call that when Array_Comp is True, with an appropriate warning for
6348 the array component case. Only create an explicit initialization
6349 by null in the case of an object of a null-excluding access type
6350 (and no longer do that in the component case).
6351 * sem_ch3.adb (Check_Component): Add a Boolean parameter
6352 Array_Comp defaulted to False. Pass Empty for the Comp
6353 actual when calling Null_Exclusion_Static_Checks in the case
6354 where Comp_Decl matches Object_Decl, because we don't have a
6355 component in that case. In the case of an object or component
6356 of an array type, pass True for Array_Comp on the recursive call

6361 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
6362 compute the linux priority from the Ada priority. Call this everywhere
6363 required. In particular, the previous version was not doing this
6364 computation when setting the ceiling priority in various places. It
6365 was just converting to C.int, which results in a ceiling that is off
6368 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6370 * sem_ch3.adb: Comment predicate inheritance.
6372 2017-05-02 Tristan Gingold <gingold@adacore.com>

6387 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
6388 here from exp_ch9, to recognize objects whose creation requires
6389 dynamic allocation, so that the proper warning can be emitted
6390 when restriction No_Implicit_Heap_Allocation is in effect.
6391 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
6392 to emit proper warning when an object that requires dynamic

6440 * checks.adb (Apply_Constraint_Check): Do not apply
6441 a discriminant check when the associated type is a constrained
6442 subtype created for an unconstrained nominal type.
6443 * exp_attr.adb: Minor reformatting.
6445 2017-05-02 Bob Duff <duff@adacore.com>

6457 operator /= into negation of operator = when needed.
6458 (Expand_SPARK): Call new
6459 function to expand operator /=.
6461 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6463 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
6464 Simplify the expression for a fixed-fixed division to remove
6465 divisions by constants whenever possible, as an optimization
6466 for restricted targets.
6468 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
6470 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
6472 2017-05-02 Bob Duff <duff@adacore.com>
6474 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6475 to find primitive ops, instead of using an Identifier that will
6476 later be looked up. This is necessary because these ops are not
6477 necessarily visible at all places where we need to call them.
6478 * exp_util.ads: Minor comment fix.
6480 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6482 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6483 references are fully conformant if they are both expansions
6484 of the discriminant of a protected type, within one of the
6485 protected operations. One occurrence may be expanded into a
6486 constant declaration while the other is an input parameter to
6487 the corresponding generated subprogram.

6491 * sem_ch3.adb (Check_For_Null_Excluding_Components): Created for
6492 recursivly searching composite-types for null-excluding access
6493 types and verifying them.
6494 (Analyze_Object_Declaration): Add a
6495 call to Check_Null_Excluding_Components for static verification
6496 of non-initialized objects.
6497 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added
6498 a parameter for a composite-type's component and an extra case
6499 for printing component information.

6503 * sem_ch10.adb (Analyze_Subunit): Take
6504 configuration pragma into account when restoring appropriate
6505 pragma for analysis of subunit.

6517 array components specially.
6519 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6521 * sem_ch8.adb (Premature_Usage): If the premature usage of
6522 an entity is as the expression in its own object decaration,
6523 rewrite the reference as Any_Id to prevent cascaded errors or
6524 compiler loops when such an entity is used in an address clause.
6526 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6528 * gcc-interface/decl.c (components_to_record): Add missing guard.
6530 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6532 * gcc-interface/decl.c (components_to_record): Add more comments.
6533 Put back pending fields onto the regular list if the misalignment
6534 happens to cancel itself.
6536 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6538 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
6539 controlling actual in a prefixed call, preserve the original node
6540 information if the prefix itself has been rewritten, for ASIS use.
6542 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6544 * exp_ch6.adb (Insert_Post_Call_Actions):
6545 Code clean up. Insert the post-call actions after an enclosing
6546 procedure call when N denotes a function call and appears as an
6547 actual parameter in the procedure call.
6549 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6551 * freeze.adb (Check_Component_Storage_Order): If there is a clause
6552 for the component, also reject the attribute if the component
6553 doesn't end on a byte boundary and its scalar storage order is
6554 different from that of the enclosing record type.
6556 2017-04-28 Javier Miranda <miranda@adacore.com>
6558 * atree.ads (Info_Messages): Removed.

6588 2017-04-28 Bob Duff <duff@adacore.com>
6590 * sem_util.ads, sem_util.adb (Might_Raise): New function
6591 that replaces Is_Exception_Safe, but has the opposite
6592 sense. Is_Exception_Safe was missing various cases -- calls inside
6593 a pragma Debug, calls inside an 'if' or assignment statement,
6594 etc. Might_Raise now walks the entire subtree looking for things
6596 * exp_ch9.adb (Is_Exception_Safe): Remove.
6597 (Build_Protected_Subprogram_Body): Replace call to
6598 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
6599 constants where possible).
6600 * exp_ch7.adb: Rename Is_Protected_Body -->
6601 Is_Protected_Subp_Body. A protected_body is something different
6604 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>

6630 * sem_ch13.adb (Analyze_Aspect_Specifications, case
6631 Interrupt_Handler and Attach_Handler): Generate reference
6632 to protected operation to prevent spurious warnings about
6633 unreferenced entities. Previous scheme failed with style checks
6636 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6638 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6639 that follows an expression function must not be relocated to
6640 the generated body, because it applies to the code that follows.
6642 2017-04-28 Gary Dismukes <dismukes@adacore.com>
6644 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
6645 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
6646 code that might violate the more stringent checking for 'Access
6647 introduced in Ada 2005.
6649 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6651 * a-cforse.adb: minor style fix in comment.
6653 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6655 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
6656 initialize Block_Decls variable.
6657 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
6658 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.

6667 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
6669 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6671 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
6672 node between access types, freeze the designated type as well,
6673 so that dispatch table pointers are created in the proper scope,
6674 and not in the constructed body of the expression function.
6676 2017-04-28 Bob Duff <duff@adacore.com>
6678 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6679 value makes large compilations faster, but small compilations slower.
6681 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6683 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
6685 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6687 * erroutc.adb (Compilation_Errors): Do not consider info messages
6688 as suitable warnings when warnings must be treated as errors.
6689 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
6690 internally-generated packages when outputting completion
6692 * errout.adb (Output_Messages): Do not consider info messages as

6695 suitable warnings when warnings must be treated as errors.
6697 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6699 * warnsw.ads: Minor fix for incorrect wording in comment.
6701 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6703 * sem_res.adb (In_Instance_Code): New predicate in
6704 Valid_Conversion, to determine whether a type conversion appears
6705 as (or within) an actual for a formal object. Type conversions
6706 in instances are not rechecked in Valid_Conversion because
6707 visibility changes between generic location andi instance may
6708 lead to spurious errors, but conversions within an actual must be
6709 fully checked, and they are not fully resolved when pre-analyzing
6712 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6714 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
6715 New_Copy_Tree instead of Relocate_Node as any subsequent copies
6716 of the relocated node will have mangled Parent pointers.
6717 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
6718 tables used in conjunction with entity and itype replication.
6719 (Visit_Entity): Rewrite the restriction on which entities
6720 require duplication. The restriction now includes all types.

6754 (Restore_Warnings): Likewise.
6755 (Save_Warnings): Likewise.
6756 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
6757 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
6758 components_to_record.
6759 (gnu_field_to_gnat): New function.
6760 (warn_on_field_placement): Likewise.
6761 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
6762 parameters. Rename local variables and adjust recursive call.
6763 Rework final scan of the field list and implement warnings on the
6764 problematic placement of specific sorts of fields.
6766 2017-04-27 Bob Duff <duff@adacore.com>
6768 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,

6773 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
6774 For efficiency, cache results of Is_Internal_File_Name and
6775 Is_Predefined_File_Name in the Units table. This avoids a lot
6776 of repeated text processing.
6778 2017-04-27 Emmanuel Briot <briot@adacore.com>
6780 * g-comlin.adb (Sort_Sections): remove useless test.
6782 2017-04-27 Claire Dross <dross@adacore.com>
6784 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
6785 allow the use of regular equality over elements in contracts.
6786 (Formal_Model): Ghost package containing model functions that are
6787 used in subprogram contracts.
6788 (Current_To_Last): Removed, model functions should be used instead.
6789 (First_To_Previous): Removed, model functions should be used instead.
6790 (Strict_Equal): Removed, model functions should be used instead.
6791 (No_Overlap): Removed, model functions should be used instead.
6792 (Equivalent_Keys): Functions over cursors are removed. They were
6793 awkward with explicit container parameters.
6794 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
6795 allow the use of regular equality over elements in contracts.
6796 (Formal_Model): Ghost package containing model functions that

6805 * gnat1drv.adb: Code cleanup.
6807 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6809 * exp_util.adb (Replace_Entity): The prefix of a 'Result
6810 attribute reference in a post- condition is the subprogram to
6811 which the condition applies. If the condition is inherited
6812 by a type extension, the prefix becomes a reference to the
6813 inherited operation, but there is no need to create a wrapper
6814 for this operation, because 'Result is expanded independently
6815 when elaborating the postconditions.
6817 2017-04-27 Bob Duff <duff@adacore.com>
6819 * sinput.adb: Minor code cleanup.
6820 * namet.adb (Append): Create faster versions of
6821 Append(String) and Append(Name_Id) by using slice assignment
6823 * sem_util.adb (In_Instance): Speed this up by removing
6824 unnecessary tests; Is_Generic_Instance is defined for all
6826 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
6827 Remove unused function.
6828 * alloc.ads (Nodes_Initial): Use a much larger value, because
6829 the compiler was spending a lot of time copying the nodes table
6830 when it grows. This number was chosen in 1996, so is rather out
6831 of date with current memory sizes. Anyway, it's virtual memory.
6832 Get rid of Orig_Nodes_...; use Node_... instead.
6833 * atree.adb (Lock): Do not release the Nodes tables; it's a
6835 Orig_Nodes_ ==> Nodes_
6836 * nlists.adb: Orig_Nodes_ ==> Nodes_
6837 * g-table.adb: Remove unused "with" clause.
6838 * g-table.ads, table.ads: Remove Big_Table_Type, which should
6839 not be used by clients.
6840 * g-dyntab.adb (Last_Allocated): New function
6841 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
6843 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6845 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated
6847 (Subtypes_Statically_Match): Remove duplicate check.

6864 for qualified expressions, type conversions, and unchecked
6866 * sem_util.adb (Compile_Time_Constraint_Error): Merge the
6867 processing for Ada 83 and instances.
6868 (Object_Access_Level): Merge the processing for indexed components
6869 and selected components.
6870 * uname.adb (Add_Node_Name): Merge the processing for stubs.

6880 * exp_disp.adb (Build_Class_Wide_Check): New subsidiary
6881 of Expand_Dispatching_Call. If the denoted subprogram has a
6882 class-wide precondition, this is the only precondition that
6883 applies to the call, rather that the class-wide preconditions
6884 that may apply to the body that is executed. (This is specified
6887 2017-04-27 Yannick Moy <moy@adacore.com>
6889 * gnat1drv.adb (Adjust_Global_Switches): Issue
6890 a warning in GNATprove mode if the runtime library does not
6891 support IEEE-754 floats.
6893 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6895 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
6896 is itself inherited it does not carry any contract information,
6897 so examine its parent operation which is its Alias.
6899 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6901 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
6902 prefix can be an object reference in which case Obj'Image (X)
6903 can only be interpreted as an indexing of the parameterless
6904 version of the attribute.
6905 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
6906 an indexing or a slice operation if the attribute does not require

7415 formulas in contracts are factorized in independant functions
7416 with a name and a comment. Names of parameters are improved.
7418 2017-04-27 Gary Dismukes <dismukes@adacore.com>
7420 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
7422 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7424 * sem_res.adb (Resolve_Type_Conversion): Do not
7425 install a predicate check here since this is already done during
7426 the expansion phase. Verify whether the operand satisfies the
7427 static predicate (if any) of the target type.
7428 * sem_ch3.adb (Analyze_Object_Declaration): Do
7429 not install a predicate check if the object is initialized by
7430 means of a type conversion because the conversion is subjected

7454 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
7455 in gnat1 and gnatbind.
7456 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
7457 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o

7465 modifications in functional containers.
7466 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
7467 to improve readablity. Subprograms are separated between basic
7468 operations, constructors and properties. Universally quantified
7469 formulas in contracts are factorized in independant functions
7470 with a name and a comment. Names of parameters are improved.
7472 2017-04-27 Gary Dismukes <dismukes@adacore.com>

7483 not install a predicate check if the object is initialized by
7484 means of a type conversion because the conversion is subjected

7496 a-cofuma.ads, a-cofuba.adb, a-cofuba.ads: Minor reformatting.
7498 2017-04-27 Tristan Gingold <gingold@adacore.com>
7500 * s-excmac-gcc.ads, s-excmac-gcc.adb,
7501 s-excmac-arm.ads, s-excmac-arm.adb (New_Occurrence): Rewrite it in
7504 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7506 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
7507 the loop which detects potential enclosing transient scopes. The
7508 loop now terminates much earlier as transient scopes are bounded
7509 by packages and subprograms.
7511 2017-04-27 Claire Dross <dross@adacore.com>
7513 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
7514 allow the use of regular equality over elements in contracts.
7515 (Cursor): Type is now public so that it can be used in
7517 (Formal_Model): Ghost package containing
7518 model functions that are used in subprogram contracts.
7519 (Current_To_Last): Removed, model functions should be used
7521 (First_To_Previous): Removed, model functions should
7523 (Strict_Equal): Removed, model functions
7524 should be used instead.
7525 (Append): Default parameter value
7526 replaced by new wrapper to allow more precise contracts.

7544 Default_Initial_Condition procedure of a type under the SPARK
7545 elaboration checks umbrella.
7547 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7549 * sem.adb (Analyze): Diagnose an illegal iterated component
7551 * sem_util.ads, sem_util.adb

7556 * adaint.c (__gnat_get_current_dir): Return 0 in length if
7558 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
7559 exception if getcwd failed.

7568 * debug.adb Change the documentation of switch -gnatd.s.
7569 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
7570 to manage the secondary stack when an enclosing scope already
7571 performs this functionality (aka relaxed management). Switch
7572 -gnatd.s may be used to force strict management in which case
7573 the block will manage the secondary stack unconditionally. Add
7574 a guard to stop the traversal when encountering a package or a
7577 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7579 * sem_res.adb (Resolve_Call): Refine further the handling of
7580 limited views of return types in function calls. If the function
7581 that returns a limited view appears in the current unit,
7582 we do not replace its type by the non-limited view because
7583 this transformation is performed int the back-end. However,
7584 the type of the call itself must be the non-limited view, to
7585 prevent spurious resolution errors.
7587 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7589 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
7590 Removed, proposed implementation using generics for class-wide
7591 preconditions proved impractical.
7592 (Class_Wide_Clone): New attribute of subprogram. Designates
7593 subprogram created for primitive operations with class-wide
7594 pre/postconditions that contain calls to other primitives. The
7595 clone holds the body of the original primitive, but the
7596 pre/postonditions do not apply to it. The original body is
7597 rewritten as a wrapper for a call to the clone.
7598 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7599 the flag is set, no code for the corresponding pre/postconditions
7600 is inserted into its body.
7602 2017-04-27 Bob Duff <duff@adacore.com>
7604 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore
7605 Scalar_Storage_Order if -gnatI is given.
7606 * sem_prag.adb (Analyze_Pragma): Ignore

7648 private child of Ada.Containers used to implement all functional
7650 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
7651 child of Ada.Containers. It provides functional indefinite unbounded
7652 maps which can be used as high level models for specification
7654 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
7655 child of Ada.Containers. It provides functional indefinite unbounded
7656 sets which can be used as high level models for specification
7658 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
7659 child of Ada.Containers. It provides functional indefinite unbounded
7660 vectors which can be used as high level models for specification
7662 * Makefile.rtl: Add new packages.
7663 * impunit.adb: Add new packages.
7665 2017-04-27 Gary Dismukes <dismukes@adacore.com>
7667 * sem_ch4.adb: Minor reformatting.
7669 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7671 * sem_ch12.adb (Analyze_Associations): minor reformatting.
7672 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
7673 point type actual that has user-defined arithmetic primitives,
7674 when there is a previous actual for a formal package that defines
7675 a fixed-point type with the parent user-defined operator.
7677 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7679 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
7680 * sem_attr.adb (Resolve_Attribute): Generate a range check when
7681 the component type allows range checks.
7683 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7685 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
7686 corresponding declaration, because formal derived types are
7687 rewritten as private extensions.
7689 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7691 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
7692 dimensions of operands if node has been analyzed already, because
7693 previous analysis and dimension checking will have removed the
7694 dimension information from the operands.
7696 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7698 * debug.adb: Document the use of switch -gnatd.s.
7699 * einfo.ads Update the documentation on attribute
7700 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
7701 the uses of these attributes from certain entities.

7703 which determines whether the block should continue to manage
7704 the secondary stack.

7753 generating C code on complex case expressions.
7755 2017-04-25 Arnaud Charlet <charlet@adacore.com>
7757 * sem_prag.adb (Analyze_Pragma): Generate a warning instead
7758 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
7759 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
7760 Ada_2012 instead of Ada_2005 to be compatible with the above
7762 * bindgen.adb: Silence new warning on pragma Ada_95.
7764 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
7766 * checks.adb (Generate_Range_Check): Revert part of previous change.

7772 parameter association in a procedure call.
7774 2017-04-25 Olivier Ramonat <ramonat@adacore.com>
7776 * prj-proc.adb, sem_util.adb, s-stposu.adb, sem_attr.adb, prj-conf.ads:
7777 Fix spelling mistakes.
7779 2017-04-25 Bob Duff <duff@adacore.com>
7781 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
7782 * sinput-p.adb: Use regular fat pointers, with bounds checking,
7783 for source buffers. Fix misc obscure bugs.
7784 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
7785 checking, for source buffers. Modify representation clause for
7786 Source_File_Record as appropriate. Move Source_File_Index_Table
7787 from spec to body, because it is not used outside the body.
7788 Move Set_Source_File_Index_Table into the private part, because
7789 it is used only in the body and in children. Use trickery to
7790 modify the dope in the generic instantiation case. It's ugly,
7791 but not as ugly as the previous method. Fix documentation.
7792 Remove obsolete code.

7808 expander is not active or when index/range checks are suppressed
7810 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
7811 Remove variants that include a Supress parameter. These routines
7812 are never used, and were introduced before the current scope-based
7813 check suppression method.
7815 2017-04-25 Vasiliy Fofanov <fofanov@adacore.com>
7817 * prj-part.adb, cstreams.c, osint.adb, osint.ads: Remove VMS specific

7835 is now carried out by Null_Status.
7836 (Null_Status): New routine.

7842 * sem_ch6.adb (Analyze_Expression_Function): Do not report an
7843 error on the return type of an expression function that is a
7844 completion, if the type is derived from a generic formal type.
7846 2017-04-25 Ed Schonberg <schonberg@adacore.com>

7864 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
7865 the Internal_Source buffer. This removes the incorrect call to "="
7866 the customer noticed.
7867 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
7868 eventually need to eliminate them altogether. Or else get rid
7869 of zero-origin addressing.
7871 2017-04-25 Claire Dross <dross@adacore.com>
7873 * exp_util.ads (Expression_Contains_Primitives_Calls_Of): New

8437 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
8438 dereference is introduced for the object, and the object is
8439 overloaded, do not check whether it is aliased, because it may
8440 include an implicit dereference.
8441 * sem_type.adb (Disambiguate): If two interpretations are access
8442 attribute types with the same designated type keep either of
8443 them and do not report an ambiguity. A true ambiguity will be
8446 2017-04-25 Bob Duff <duff@adacore.com>
8448 * a-numeri.ads: Change the encoding of Greek letter Pi from
8449 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
8450 to indicate the encoding. We considered using a byte order mark
8451 (BOM), but that causes various trouble (misc software eats the
8452 BOM, if you have a patch with a BOM, then it's not at the start
8453 of the patch, so it's not a BOM, the BOM affects with-ing files,

8497 enforce legality rule on classwide preconditions inherited from
8498 both an ancestor and a progenitor (RM 6.1.1 (10-13).
8499 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
8500 subprogram need not be dispatching if it appears in a precondition
8501 for an abstract or null subprogram.
8503 2017-04-25 Gary Dismukes <dismukes@adacore.com>

8509 * gcc-interface/Makefile.in: Cleanup VxWorks targets.
8511 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8513 * fname.adb (Is_Internal_File_Name): Arrange for the slices to
8514 have a length which is a power of 2.
8515 (Is_Predefined_File_Name): Likewise. Adjust comment.
8517 2017-04-25 Bob Duff <duff@adacore.com>
8519 * exp_aggr.adb (Component_Count): Protect the
8520 arithmetic from attempting to convert a value >= 2**31 to Int,
8521 which would otherwise raise Constraint_Error.
8523 2017-04-25 Bob Duff <duff@adacore.com>
8525 * opt.ads (Locking_Policy): Fix incorrect documentation. The

8549 Save and restore the value of global flag
8550 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value

8552 the corresponding spec or the body must ignore all SPARK_Mode
8553 pragmas found within.
8554 (Analyze_Subprogram_Declaration): Mark
8555 the spec when it needs to ignore all SPARK_Mode pragmas found
8556 within to allow the body to infer this property in case it is
8557 instantiated or inlined later.
8558 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
8559 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
8560 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
8561 when the corresponding spec also ignored all SPARK_Mode pragmas
8563 (Analyze_Package_Declaration): Mark the spec when
8564 it needs to ignore all SPARK_Mode pragmas found within to allow

8568 Save and restore the value of flag
8569 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
8570 formal spec when it needs to ignore all SPARK_Mode
8571 pragmas found within to allow the body to infer this
8572 property in case it is instantiated or inlined later.
8573 (Analyze_Package_Instantiation): Save and restore the value
8574 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark

8594 Ignore_Pragma_SPARK_Mode.
8595 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
8596 all SPARK_Mode pragmas defined within yields mode "off".
8598 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

8617 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8619 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
8620 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
8621 variable and set it to True whenever the main hash table is
8622 populated. Short- circuit the Assoc function if it is false
8623 and add associated guards.
8625 2017-04-25 Olivier Hainque <hainque@adacore.com>
8627 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
8628 specs without elaboration code that have an elaboration counter
8629 nevertheless, e.g. when compiled with -fpreserve-control-flow.
8630 * sem_ch10.adb (Analyze_Compilation_Unit):
8631 Set_Elaboration_Entity_Required when requested to preserve
8632 control flow, to ensure the unit elaboration is materialized at
8633 bind time, resulting in the inclusion of the unit object file
8634 in the executable closure at link time.
8636 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8638 * exp_dbug.adb: In Debug_Renaming_Declaration,
8639 when dealing with indexed component, accept to produce a renaming
8640 symbol when the index is an IN parameter or when it is a name
8641 defined in an outer scope.
8643 2017-04-25 Yannick Moy <moy@adacore.com>
8645 * errout.adb (Error_Msg): Adapt continuation
8646 message in instantiations and inlined bodies for info messages.
8648 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8650 * fname.adb (Has_Internal_Extension): Add pragma Inline.
8651 Use direct 4-character slice comparisons.
8653 pragma Inline. (Has_Suffix): Delete.
8654 (Is_Internal_File_Name):
8655 Test Is_Predefined_File_Name first.
8656 (Is_Predefined_File_Name):

8660 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8662 * checks.adb (Insert_Valid_Check): Code cleanup.
8663 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8664 (Expand_Actuals): Generate proper copy-back for a validation
8665 variable when it acts as the argument of a type conversion.
8666 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8667 predicate to operate on type qualifications.
8669 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8671 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8674 2017-04-25 Bob Duff <duff@adacore.com>
8676 * sem_prag.adb (No_Return): Give an error if the pragma applies
8677 to a body. Specialize the error for the specless body case,
8678 as is done for (e.g.) pragma Convention.
8679 * debug.adb: Add switch -gnatd.J to disable the above legality
8680 checks. This is mainly for use in our test suite, to avoid
8681 rewriting a lot of illegal (but working) code. It might also
8682 be useful to customers. Under this switch, if a pragma No_Return
8683 applies to a body, and the procedure raises an exception (as it
8684 should), the pragma has no effect. If the procedure does return,
8685 execution is erroneous.
8687 2017-04-25 Bob Duff <duff@adacore.com>
8689 * exp_ch6.adb (Expand_Actuals): This is the
8690 root of the problem. It took N as an 'in out' parameter, and in
8691 some cases, rewrote N, but then set N to Original_Node(N). So
8692 the node returned in N had no Parent. The caller continued
8693 processing of this orphaned node. In some cases that caused a
8694 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8695 and trips over the Empty Parent). The solution is to make N an
8696 'in' parameter. Instead of rewriting it, return the list of
8697 post-call actions, so the caller can do the rewriting later,
8698 after N has been fully processed.
8699 (Expand_Call_Helper): Move most of Expand_Call here. It has
8700 too many premature 'return' statements, and we want to do the
8701 rewriting on return.
8702 (Insert_Post_Call_Actions): New procedure to insert the post-call
8703 actions in the appropriate place. In the problematic case,
8704 that involves rewriting N as an Expression_With_Actions.
8705 (Expand_Call): Call the new procedures Expand_Call_Helper and
8706 Insert_Post_Call_Actions.
8708 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8710 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
8711 properly type derived from generic formal types, to handle
8712 properly modified version of ACATS 4.1B B611017.
8714 2017-04-25 Javier Miranda <miranda@adacore.com>
8716 * exp_unst.adb (Subp_Index): Adding missing
8717 support for renamings and functions that return a constrained
8718 array type (i.e. functions for which the frontend built a
8719 procedure with an extra out parameter).
8721 2017-04-25 Pascal Obry <obry@adacore.com>
8723 * s-string.adb: Minor code clean-up.
8725 2017-04-25 Bob Duff <duff@adacore.com>

8732 2017-04-25 Bob Duff <duff@adacore.com>
8734 * prep.adb (Preprocess): Remove incorrect
8735 Assert. Current character can be ASCII.CR.
8737 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8739 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
8740 convention Stdcall, which has a number of exceptions. Convention
8741 is legal on a component declaration whose type is an anonymous
8742 access to subprogram.
8744 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8746 * sem_ch4.adb: sem_ch4.adb Various reformattings.
8747 (Try_One_Prefix_Interpretation): Use the base type when dealing
8748 with a subtype created for purposes of constraining a private
8749 type with discriminants.
8751 2017-04-25 Javier Miranda <miranda@adacore.com>
8753 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.

8755 dispatching primitives (Restore_Warnings): Restore warning on
8756 late dispatching primitives (Save_Warnings): Save warning on late
8757 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
8758 to enable/disable this warning.
8759 (WA_Warnings): Set warning on late dispatching primitives.
8760 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
8761 that its parent type has a private extension.
8762 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
8764 * usage.adb: Document -gnatw.j and -gnatw.J.
8766 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8768 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
8771 2017-04-25 Bob Duff <duff@adacore.com>
8773 * binde.adb (Validate): Do not pass dynamic strings
8774 to pragma Assert, because older compilers do not support that.
8776 2017-04-25 Bob Duff <duff@adacore.com>
8778 * s-fileio.adb (Close): When a temp file is
8779 closed, delete it and clean up its Temp_File_Record immediately,
8780 rather than waiting until later.
8781 (Temp_File_Record): Add File
8782 component, so Close can know which Temp_File_Record corresponds
8783 to the file being closed.
8784 (Delete): Don't delete temp files,
8785 because they are deleted by Close.
8786 (Open): Set the File component
8787 of Temp_File_Record. This requires moving the creation of the
8788 Temp_File_Record to the end, after the AFCB has been created.
8790 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8792 * checks.adb (Insert_Valid_Check): Do not generate
8793 a validity check when inside a generic.

8812 * s-ficobl.ads: Minor comment fix.
8814 2017-04-25 Yannick Moy <moy@adacore.com>
8816 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
8817 conversions from float to integer in GNATprove mode.
8818 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
8819 to call Apply_Type_Conversion_Checks, so that range checks
8820 are properly positioned when needed on conversions, including
8821 when converting from float to integer. (Determine_Range): In
8822 GNATprove mode, take into account the possibility of conversion
8823 from float to integer.
8824 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
8825 check on conversions from fixed-point to integer, not anymore
8826 on conversions from floating-point to integer, when in GNATprove
8829 2017-04-25 Yannick Moy <moy@adacore.com>
8831 * checks.adb (Determine_Range_R): Special case type conversions
8832 from integer to float in order to get bounds in that case too.
8833 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
8834 mode, for computations involved in interval checking.

8849 variables to avoid extra reads and copies of the prefix.
8850 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
8851 variables in order to reflect any changes done in the variable
8852 back into the original object.
8853 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
8854 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

8862 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8864 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
8865 Analyze_Pre_Post_Condition, to implement the legality checks
8866 mandated by AI12-0131: Pre'Class shall not be specified for an
8867 overriding primitive subprogram of a tagged type T unless the
8868 Pre'Class aspect is specified for the corresponding primitive
8869 subprogram of some ancestor of T.
8871 2017-04-25 Bob Duff <duff@adacore.com>
8873 * sem_ch8.adb (Use_One_Type): If a use_type_clause
8874 is redundant, set its Used_Operations to empty. This is only
8875 necessary for use clauses that appear in the parent of a generic
8876 child unit, because those use clauses get reanalyzed when we
8877 instantiate the generic, and we don't want the Used_Operations
8878 carried over from the original context (where it was probably
8881 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

8897 'Class, if prefix type is synchronized and previous errors
8898 have suppressed the creation of the corresponding record type,
8899 create a spurious class-wide for the synchonized type itself,
8900 to catch other misuses of the attribute

8922 (Expand_Concatenate): When optimization is enabled, also expand
8923 the operation out-of-line if the concatenation is present within
8924 the expression of the declaration of a library-level object and
8925 not only if it is the expression of the declaration.
8927 2017-04-25 Bob Duff <duff@adacore.com>
8929 * freeze.adb (Freeze_Object_Declaration): Do
8930 not Remove_Side_Effects if there is a pragma Linker_Section,
8931 because in that case we want static initialization in the
8932 appropriate section.
8934 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8936 * exp_dbug.adb: Minor rewording and reformatting.
8938 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8940 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
8941 handle the proposed changes to rules concerning potentially
8942 unevaluated expressions, to include selected components that
8943 do not depend on discriminants, and indexed components with
8945 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
8946 predicate in quantified expression, and fix bugs in the handling
8947 of case expressions and membership test.

8965 renaming entity for debug information, mark the entity as needing debug
8966 info if it comes from sources.
8968 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8970 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the

8989 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
8990 internal calls that appear in preconditions of protected
8991 operations, in default values for same, and in contract guards
8992 for contract cases in SPARK.
8994 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8996 * a-numaux.ads: Fix description of a-numaux-darwin

9003 * a-numaux-x86.ads: Fix package description.
9004 * a-numaux-x86.adb (Is_Nan): Minor tweak.
9005 (Reduce): Adjust and complete description. Call Is_Nan instead of
9006 testing manually. Use an integer temporary to hold rounded value.
9007 * a-numaux-darwin.adb (Reduce): Likewise.
9008 (Is_Nan): New function.
9010 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9012 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
9013 on analysis of prefix whose type is a current instance of a
9014 synchronized type, but where the prefix itself is an entity that
9017 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9019 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
9020 the identity of callable entities therein, because they have been
9021 properly resolved, and prefixed calls may have been rewritten
9024 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
9026 * exp_ch3.adb (Build_Init_Statements): Convert
9027 the expression of the pragma/aspect Secondary_Stack_Size to
9028 internal type System.Parameters.Size_Type before assigning
9029 it to the Secondary_Stack_Size component of the task type's
9030 corresponding record.

9040 * s-osinte-freebsd.ads: Minor comment tweaks
9042 2017-04-25 Javier Miranda <miranda@adacore.com>
9044 * urealp.adb (UR_Write): Reverse previous patch
9045 adding documentation on why we generate multiplications instead
9046 of divisions (needed to avoid expressions whose computation with
9047 large numbers may cause division by 0).
9049 2017-04-25 Bob Duff <duff@adacore.com>
9051 * erroutc.adb (Set_Specific_Warning_Off,
9052 Set_Warnings_Mode_Off): Use the correct source file for
9053 Stop. Was using Current_Source_File, which is only valid during
9054 parsing. Current_Source_File will have a leftover value from
9055 whatever file happened to be parsed last, because of a with_clause
9058 2017-04-25 Bob Duff <duff@adacore.com>
9060 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
9061 to In_Predefined_Unit, but including GNAT units.
9062 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
9063 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
9064 because Should_Ignore_Pragma was not working reliably outside
9065 the parser, because Current_Source_File is not valid.
9066 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
9067 * par-prag.adb: Call Should_Ignore_Pragma_Par.

9104 Build_Invariant_Procedure_Body.
9105 (Build_Invariant_Procedure_Body):
9106 Remove refactored calls and integrated code from
9107 Add_Parent_Invariants and Add_Interface_Invariants.
9109 2017-04-25 Johannes Kanig <kanig@adacore.com>
9111 * errout.adb (Output_Messages): Adjust computation of total
9113 * erroutc.adb (Error_Msg): In statistics counts, deal
9114 correctly with informational messages that are not warnings.

9126 2017-04-25 Justin Squirek <squirek@adacore.com>
9128 * sem_ch3.adb (Analyze_Declarations): Minor
9129 correction to comments, move out large conditional and scope
9130 traversal into a predicate.
9131 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
9134 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9136 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
9137 of prefix whose type is a current instance of a synchronized
9138 type. If the prefix is an object this is an external call (or
9139 requeue) that can only access public operations of the object. The
9140 previous predicate was too restrictive, and did not allow public
9141 protected operations, only task entries.
9143 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9145 * sem_ch5.adb, fname.adb: Minor reformatting.
9147 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9149 * einfo.adb (Is_Anonymous_Access_Type): New routine.
9150 * einfo.ads Update the placement of
9151 E_Anonymous_Access_Subprogram_Type along with all subtypes that
9153 (Is_Anonymous_Access_Type): New routine.
9154 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
9155 master for an access type subject to pragma No_Heap_Finalization.
9156 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
9157 allocated or deallocated does not finalization actions if the
9158 associated access type is subject to pragma No_Heap_Finalization.
9159 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
9160 * par-prag.adb Pragma No_Heap_Finalization does not need special
9161 processing from the parser.
9162 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
9163 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
9164 * sem_prag.adb Add an entry in table Sig_Flags for pragma
9165 No_Heap_Finalization.
9166 (Analyze_Pragma): Add processing for
9167 pragma No_Heap_Finalization. Update various error messages to
9168 use Duplication_Error.
9169 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
9170 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
9171 and corresponding pragma id.
9173 2017-04-25 Bob Duff <duff@adacore.com>
9175 * freeze.adb (Freeze_Record_Type): Use the
9176 underlying type of the component type to determine whether it's
9177 elementary. For representation clause purposes, a private type
9178 should behave the same as its full type.
9179 * fname.ads, fname.adb (Is_Predefined_File_Name):
9180 Make sure things like "system.ali" are recognized as predefined.
9182 2017-04-25 Javier Miranda <miranda@adacore.com>

9188 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
9189 element iterator when the name is an overloaded function call,
9190 one of whose interpretations yields an array.
9192 2017-04-25 Bob Duff <duff@adacore.com>
9194 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
9195 Is_Internal_Unit_Name): New functions for operating on unit
9196 names, as opposed to file names. There's some duplicated code
9197 with fname.adb, which is unfortunate, but it seems like we don't
9198 want to add dependencies here.
9199 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
9200 to Is_Predefined_Unit_Name; the former was wrong, because Uname
9201 is not a file name at all.
9202 * fname.ads, fname.adb: Document the fact that
9203 Is_Predefined_File_Name and Is_Internal_File_Name can be called
9204 for ALI files, and fix the code so it works properly for ALI
9205 files. E.g. these should return True for "system.ali".
9207 2017-04-25 Justin Squirek <squirek@adacore.com>
9209 * exp_util.adb (Add_Invariant): Removed,
9210 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
9211 and Add_Own_Invariant. (Add_Invariant_Check): Used
9212 for adding runtime checks from any kind of invariant.
9213 (Add_Inherited_Invariant): Generates invariant checks for
9214 class-wide invariants (Add_Interface_Invariants): Removed, code
9215 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):

9217 Removed, code moved to Build_Invariant_Procedure_Body
9218 (Build_Invariant_Procedure_Body): Add refactored calls
9219 and integrated code from Add_Parent_Invariants and
9220 Add_Interface_Invariants.
9221 (Process_Type): Removed, the
9222 relavant code was inlined into both Add_Own_Invariant and
9223 Add_Inherited_Invariant.
9225 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9227 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

9244 and Build_Invariant_Procedure_Declaration.
9245 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
9246 and Build_Invariant_Procedure_Declaration from exp_ch7
9247 and break-out Is_Untagged_Private_Derivation from
9248 Build_Invariant_Procedure_Body.
9249 (Replace_Type_References):
9250 Append an extra parameter to allow for dispatching replacements
9251 and add the corrasponding logic.
9252 (Type_Invariant): Remove
9253 Replace_Typ_Refs and replace its references with calls to
9254 Replace_Type_References.
9255 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
9257 2017-04-25 Bob Duff <duff@adacore.com>
9259 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
9260 that returns True when appropriate.
9261 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
9262 when compiling predefined files.
9263 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
9264 "gnat.adc" should not be considered a predefined file name.
9265 That required (or at least encouraged) a lot of cleanup of global
9266 variable usage. We shouldn't be communicating information via
9267 the global name buffer.
9268 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
9269 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

9274 * osint.adb (Find_File): Handle properly a request for a
9275 configuration file whose name is a directory.

9289 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
9290 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
9291 Add String_To_Name with no side effects.
9293 2017-04-25 Justin Squirek <squirek@adacore.com>
9295 * sem_ch3.adb (Analyze_Declarations): Add
9296 additional condition for edge case.

9300 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
9301 reserved words inside pragmas. This is necessary to allow the
9302 pragma name Interface to be used in pragma Ignore_Pragma.

9305 2017-04-25 Javier Miranda <miranda@adacore.com>
9307 * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.

9328 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
9329 the first pass over an assignment statement with target names,
9330 to prevent the generation of subtypes (such as discriminated
9331 record components)that may carry the target name outside of the
9332 tree for the assignment. The subtypes will be generated when
9333 the assignment is reanalyzed in full.
9334 (Analyze_Target_Name): Handle properly class-wide types.

9348 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
9349 are now only processed when freezing occurs. Build a body only

9366 properties of the private type to the full view in case the full
9367 view derives from a parent type and inherits a DIC pragma.
9368 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
9369 DIC pragma is placed at the top of a declarative region.
9371 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
9373 * a-tasatt.adb: Complete previous change and use an unsigned
9374 int to avoid overflow checks.
9376 2017-04-25 Ed Schonberg <schonberg@adacore.com>

9379 the error message when the attribute reference is an actual in
9380 a call to a subprogram inherited from a generic formal type with
9381 unknown discriminants, which makes the subprogram and its formal
9382 parameters intrinsic (see RM 6.3.1 (8) and (13)).
9384 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9386 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

9391 * sem_attr.adb (Type_Key): Add code in the
9392 recursive Compute_Type_Key to protect against fetching the source
9393 code for Standard, in case a component of the type is declared
9394 in Standard. There was already code to do this for the original
9395 type, but not for its components.
9397 2017-04-25 Javier Miranda <miranda@adacore.com>
9399 * exp_ch3.adb (Build_Initialization_Call): Handle
9400 subtypes of private types when searching for the underlying full
9401 view of a private type.

9405 * sem_res.adb (Set_Mixed_Mode_Operand): A universal
9406 real conditional expression can appear in a fixed-type context

9414 appears in the context of a unit U2 compiled for instantiation
9415 or inlining purposes, the body of U1 needs to be compiled as well.
9416 * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
9417 context is a package declaration.
9418 * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration,
9419 Analyze_Generic_Package_Declaration): ditto.

10093 (Check_Dependency_Clause): Properly detect a match between two
10094 'Result attributes. Update the various post-match cases to use

10098 (Remove_Extra_Clauses): New routine.
10099 (Report_Extra_Clauses): Remove the detection of ... => null
10100 clauses as this is now done in Remove_Extra_Clauses.
10102 2017-01-23 Ed Schonberg <schonberg@adacore.com>
10104 * sem_aggr.adb (Resolve_Array_Aggregate): In ASIS mode do not
10105 report on spurious overlaps between values involving a subtype
10106 with a static predicate, because the expansion of such a subtype
10107 into individual ranges in inhibited in ASIS mode.

10111 * sem_ch3.adb (Analyze_Declarations): Add detection

10139 to the expected type with the appropriate check flags set.
10140 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
10141 base type if the range is null. It may still be invalid if it
10142 is higher than the lower bound. This is checked later in the

10158 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
10159 an object declaration for an array type with a modular index type
10160 with the size of Long_Long_Integer. Special processing is needed
10161 in this case to compute reliably the size of the object, and
10162 eventually to raise Storage_Error, when wrap-around arithmetic
10163 might compute a meangingless size for the object.
10165 2017-01-23 Justin Squirek <squirek@adacore.com>
10167 * a-wtenau.adb, par-endh.adb, sem_prag.adb,

10172 * sem_res.adb (Resolve_Call): In the part of the code where
10173 it is deciding whether to turn the call into an indexed
10174 component, avoid doing so if the call is to an instance of
10175 Unchecked_Conversion. Otherwise, the compiler turns it into an
10176 indexed component, and resolution of that turns it back into a
10177 function call, and so on, resulting in infinite recursion.
10178 * sem_util.adb (Needs_One_Actual): If the first formal has a
10179 default, then return False.

10224 2017-01-20 Ed Schonberg <schonberg@adacore.com>
10226 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
10227 must be treated as delayed aspect even if the expression is
10228 a literal, because the aspect affects the freezing and the
10229 elaboration of the object to which it applies.

10280 * sem_res.adb (Resolve_Call): If a function call
10281 returns a limited view of a type and at the point of the call the
10282 function is not declared in the extended main unit then replace
10283 it with the non-limited view, which must be available. If the
10284 called function is in the extended main unit then no action is
10285 needed since the back-end handles this case.

10307 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
10308 When inheriting the SPARK_Mode of a prior expression function,

10399 * sem_ch3.adb (Check_Non_Overridable_Aspects): An inherited
10400 aspect Implicit_Dereference can be inherited by a full view if
10401 the partial view has no discriminants, because there is no way
10402 to apply the aspect to the partial view.

10537 * sem_aggr.adb (Resolve_Aggregate): If the type is a string
10538 type, ie. a type whose component is a character type, and the
10539 aggregate is positional, do not convert into a string literal
10540 if the index type is not an integer type, because the original

10598 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
10599 (Build_Derived_Enumeration_Type): If the derived type inherits a
10600 dynamic predicate from its parent, the bounds of the type must
10601 freeze because an explicit constraint is constructed for the
10602 type and the corresponding range is elaborated now.

10640 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
10641 in case of generic formal discrete types, because it causes crashes in

10653 wrong since we just issued a warning message.
10654 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
10655 these variables to be of subtype Nat instead of Int, because
10656 they should never be negative.

10687 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10689 * sem_ch4.adb (Diagnose_Call): Improve error message when a
10690 selected component has a prefix that might be interpreted
10691 as a parameterless function call, but none of the candidate
10692 interpretations is parameterless, and there is a hidden homonym
10693 of the prefix that is a package.
10694 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
10695 interpreted as a parameterless function call and its analysis
10696 fails, do not call Analyze_Selected_Component.
10698 2017-01-19 Steve Baird <baird@adacore.com>
10700 * sem_util.ads: Add new Use_Full_View Boolean parameter to
10702 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with

10707 * gnat1drv.adb: minor fix of unbalanced parens in comment
10708 * lib-xref.ads (Traverse_Compilation_Unit): declaration moved
10709 to visible part of the package to allow re-use in GNATprove.
10710 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
10711 from repeated code of Traverse_Compilation_Unit.
10712 (Traverse_Declaration_Or_Statement): fixed detection of
10713 generic subprograms and packages; also, iteration over case
10714 statement alternatives rewritten to avoid testing if the first
10715 alternative is present (since it must be present due to Ada
10716 syntax restrictions).
10718 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
10720 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as

10730 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
10731 identifier nodes that do not come from source, to handle properly
10732 dimensionality check within an inlined body which inclddes both
10733 original operands and rewritten operands. This removes spurious
10734 dimensionality errors in the presence of front-end inlining,
10735 as well as in SPARK mode.
10737 2017-01-16 Jakub Jelinek <jakub@redhat.com>

10776 * scil_ll.adb: Minor style fix in comment.
10777 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
10778 even if entity is already set, because the node may be renalyzed
10779 after inlining transformations.
10781 2017-01-13 Javier Miranda <miranda@adacore.com>
10783 * sem_res.adb (Resolve_Call): Do not establish a transient scope

10809 (Freeze_Expr_Types): Complete previous patch since the expression
10810 of an expression-function may have iterators and loops with
10811 defining identifiers which, as part of the preanalysis of the
10812 expression, may be left decorated with itypes that will not be
10813 available in the tree passed to the backend.
10815 2017-01-13 Ed Schonberg <schonberg@adacore.com>

10853 2017-01-13 Bob Duff <duff@adacore.com>
10855 * binde.adb (Elab_New): New elaboration order algorithm
10856 that is expected to cause fewer ABE issues. This is a work in
10857 progress. The new algorithm is currently disabled, and can be
10858 enable by the -dp switch, or by modifying the Do_Old and Do_New
10859 etc. flags and rebuilding. Experimental code is included to
10860 compare the results of the old and new algorithms.
10861 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
10862 can have multiple of these tables, so the old and new algorithms
10864 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
10865 parameter of type array. This avoids the global variable, and
10866 allows bounds checking (which is normally defeated by the tables
10867 packages). It also ensures that the Elab_Order is read-only
10869 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
10870 subprograms that need it, as above.
10871 * debug.adb: Document new -dp switch. Modify doc of old -do
10873 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
10874 and Bindgen. Move writing of closure (-R and -Ra switches)

10877 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10879 * sem_ch6.adb (Analyze_Expression_Function): If the expression
10880 function is a completion, all entities referenced in the
10881 expression are frozen. As a consequence, a reference to an
10882 uncompleted private type from an enclosing scope is illegal.
10884 2017-01-13 Javier Miranda <miranda@adacore.com>
10886 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
10887 (Analyze_Subprogram_Body_Helper): At the occurrence of an
10888 expression function declaration that is a completion, its
10889 expression causes freezing (AI12-0103).
10891 2017-01-13 Vadim Godunko <godunko@adacore.com>
10893 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

10913 the legality of An others clause applies as well to a choice in
10914 an Iterated_component_ association.
10915 (Resolve_Iterated_Component_Association): An others choice
10917 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An

10947 Iterated_Component_Associations.
10948 (Gen_Loop): Generate proper loop for an

10950 of the original association. Generate a loop even for a single
10951 component choice, in order to make loop parameter visible in
10953 (Flatten): An Iterated_Component_Association is not static.
10955 2017-01-13 Yannick Moy <moy@adacore.com>
10957 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
10958 float exponentiation for statically known small negative values
10959 is the reciprocal of the exponentiation for the opposite value

10977 mode a choice that is a subtype with a static predicate is
10978 replaced by the values it covers. This transformation must not
10979 be performed in ASIS mode, to preserve the source for analysis.

10995 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
10996 and resolve the discrete choices and the expression of the
10998 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
10999 Loop_Actions and Box_Present are attributes of

11001 False in this case.
11002 * sprint.adb (Sprint_Node): An Iterated_Component_Association
11003 has a Discrete_Choices list, as specified in the RM. A
11004 Component_Association for aggregate uses instead a Choices list.

11019 Analyze_Declarations, to analyze and resolve the expressions of
11020 aspect specifications in the current declarative list, so that
11021 the expressions have proper entity and type info. This is needed

11023 semantic information.
11024 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
11025 original expression, to suppress cascaded errors when expression
11026 has been constant-folded.

11039 sees the check to perform.
11040 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
11041 when not applicable due to actual requiring type conversion
11042 with possible check but no temporary value can be copied for
11043 GNATprove to see the check.
