12 to 0 on the callee if the call is recursive.
14 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
16 * gcc-interface/decl.c (gnat_to_gnu_field): Do not set the alignment
17 of the enclosing record type if it is not already set.
19 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
21 * gcc-interface/gigi.h (pad_type_has_rm_size): Declare.
22 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Do not build
23 a padding type for the alignment before validating the size.
24 Flip conditional construct and add a comment.
25 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Size>: Make sure to
26 apply the exception for padded objects to the type of the object.
27 * gcc-interface/utils.c (hash_pad_type): New static function.
28 (lookup_and_insert_pad_type): Rename into...
29 (canonicalize_pad_type): ...this. Call hash_pad_type, do only one
30 lookup with insertion and always return the canonical type.
31 (maybe_pad_type): Adjust to above changes. Set debug type later.
32 (pad_type_has_rm_size): New predicate.
33 (set_reverse_storage_order_on_pad_type): Adjust to above changes.

46 * gcc-interface/decl.c (gnat_to_gnu_entity): Robustify test for types
47 descendant of System.Address.
48 (gnat_to_gnu_subprog_type): Likewise.
50 2017-12-08 Jakub Jelinek <jakub@redhat.com>
52 * gcc-interface/utils.c (gnat_internal_attribute_table): Add
53 exclusions to the comment.
55 2017-12-07 Martin Sebor <msebor@redhat.com>
58 * gcc-interface/utils.c (gnat_internal_attribute_table): Initialize
59 new member of struct attribute_spec.

80 2017-12-05 Jerome Lambourg <lambourg@adacore.com>
82 * libgnarl/s-taprop__qnx.adb: Better detect priority ceiling bug in
83 QNX. At startup, the first mutex created has a non-zero ceiling
84 priority whatever its actual policy. This makes some tests fail
85 (c940013 for example).
87 2017-12-05 Bob Duff <duff@adacore.com>
89 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Call
90 Expand_Cleanup_Actions for N_Extended_Return_Statement.
91 * exp_ch7.adb (Expand_Cleanup_Actions): Handle
92 N_Extended_Return_Statement by transforming the statements into a
93 block, and (indirectly) calling Expand_Cleanup_Actions on the block.
94 It's too hard for Expand_Cleanup_Actions to operate directly on the
95 N_Extended_Return_Statement, because it has a different structure than
96 the other node kinds that Expand_Cleanup_Actions.
97 * exp_util.adb (Requires_Cleanup_Actions): Add support for
98 N_Extended_Return_Statement. Change "when others => return False;" to
99 "when others => raise ...;" so it's clear what nodes this function
100 handles. Use named notation where appropriate.
101 * exp_util.ads: Mark incorrect comment with ???.
103 2017-12-05 Javier Miranda <miranda@adacore.com>
105 * exp_ch9.adb (Install_Private_Data_Declarations): Add missing
106 Debug_Info_Needed decoration of internally generated discriminal
107 renaming declaration.

117 option for gnatmetric, gnatpp, gnat2xml, and gnattest.
119 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
121 * sem_util.adb (Contains_Refined_State): Remove.
123 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
125 * rtsfind.ads: Add new enumeration literals: RE_Clock_Time (for
126 Ada.Real_Time.Clock_Time) and RO_CA_Clock_Time (for
127 Ada.Calendar.Clock_Time).
129 2017-12-05 Ed Schonberg <schonberg@adacore.com>
131 * sem_ch4.adb (Is_Private_Overriding): If the candidate private
132 subprogram is overloaded, scan the list of homonyms in the same
133 scope, to find the inherited operation that may be overridden
135 * exp_ch11.adb, exp_ch7.adb: Minor reformatting.
137 2017-12-05 Bob Duff <duff@adacore.com>
139 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
140 Init_Assignment is rewritten, we need to set Assignment_OK on the new
141 node. Otherwise, we will get spurious errors when initializing via
142 assignment statement.
144 2017-12-05 Hristian Kirtchev <kirtchev@adacore.com>
146 * sem_elab.adb: Update the terminology and switch sections.

153 (Process_Conditional_ABE_Variable_Assignment_SPARK): Verify the model
156 2017-12-05 Nicolas Setton <setton@adacore.com>
158 * terminals.c (__gnat_setup_child_communication): As documented,
159 __gnat_setup_child_communication should not terminate - it is intended
160 to be used as the child process of a call to fork(). However, execvp
161 might actually return in some cases, for instance when attempting to
162 run a 32-bit binary on a 64-bit Linux distribution when the
163 compatibility packages are not installed. In these cases, exit the
164 program to conform to the documentation.
166 2017-12-05 Olivier Hainque <hainque@adacore.com>
168 * libgnat/s-tsmona.adb: Fix for oversight in the tsmona interface
171 2017-12-05 Gary Dismukes <dismukes@adacore.com>

244 statements when debug flag d_e is in effect. Do not consider calls to
245 subprograms which verify the runtime semantics of certain assertion
246 pragmas when debug flag d_p is in effect.

257 (Is_Assertion_Pragma_Target): New routine.
258 (Is_Potential_Scenario): Stop the traversal of a task body when
259 reaching an accept or select statement, and debug switch d_a is in

329 2017-12-05 Doug Rupp <rupp@adacore.com>
331 * tracebak.c (ppc64-vx7): USE_GCC_UNWINDER for 64bit.
333 2017-12-05 Javier Miranda <miranda@adacore.com>
335 * checks.adb (Generate_Range_Check): Force evaluation of the node in
336 more cases. This patch was written to improve the code generated by
337 the CCG compiler but it is enabled for all targets since double
338 evaluation is always a potential source of inefficiency.

352 * exp_aggr.adb (Gen_Assign): Do not analyze the expressionn of the
353 assignment if it is part of an Iterated_Component_Association: the
354 analysis needs to take place once the loop structure is analyzed and
355 the loop parameter made visible, because references to it typically
356 appear in the corresponding expression. This is necessary if the
357 expression is an aggregate, because previous pre-analysis of the
358 expression does not handle nested aggregates properly.
360 2017-12-05 Bob Duff <duff@adacore.com>
362 * sem_res.adb (Resolve_Allocator): Avoid coextension processing for an
363 allocator that is the expansion of a build-in-place function call.

373 retrieved load address to Init_Module.
374 * s-tsmona__linux.adb (Get): Honor the new interface.

377 addresses are from module info and which are run-time addresses,
378 offsetted by the module load address.
379 * s-dwalin.adb (Set_Load_Address): Simply set C.Load_Slide.
380 Do not alter the module Low and High (relative) addresses.
381 (Is_Inside): Improve documentation regarding the kinds of addresses
382 at hand and correct the test.
383 (Symbolic_Traceback): Use separate variables with explicit names
384 for the address in traceback (run-time value) and the address to
385 lookup within the shared object (module-relative). Adjust the
386 computation of address passed to Symbolic_Address for symbolization.

391 * exp_ch4.adb (Expand_Nonbinary_Modular_Op): Use
392 Expand_Nonbinary_Modular_Ops instead of Modify_Tree_For_C, so that
393 other back-ends can also benefit from the front-end expansion. Remove
394 test for Modify_Tree_For_C in all callers to better share code.
395 * gnat1drv.adb (Adjust_Global_Switches): Set
396 Expand_Nonbinary_Modular_Ops when generating C code.
398 2017-12-05 Ed Schonberg <schonberg@adacore.com>
400 * exp_ch5.adb (Expand_Formal_Container_Loop): Ensure that the loop
401 parameter becomes invisible after analyzing the loop, which has been
402 rewritten as a while-loop.

407 and update for 64bit ports.
409 2017-12-05 Bob Duff <duff@adacore.com>
411 * exp_ch6.adb (Build_In_Place_Formal): Search for the formal by suffix
412 instead of the full name.
413 * sem_ch6.adb (Create_Extra_Formals): Make sure there are extra formals
414 in the case of an instance of a generic.
416 2017-12-05 Arnaud Charlet <charlet@adacore.com>
418 (Adjust_Global_Switches): Create an alias GNAT_Annotate to map to

442 2017-11-28 Jakub Jelinek <jakub@redhat.com>
444 * gcc-interface/trans.c (Case_Statement_to_gnu): Build SWITCH_EXPR
445 using build2 instead of build3.

894 only for foreign threads. We initialize the thread handle only if not

999 * freeze.adb (Check_Component_Storage_Order): Default initialize
1000 Comp_Byte_Aligned rather than silencing messages with pragma
1001 Warnings(Off), which does not work for CodePeer initialization
1002 messages, and given that here the possible read of an unitialized value
1003 depends on a proper use of parameters by the caller.

1014 * sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,
1015 and restructure code to defend against previous errors, so that, in

2451 2017-10-09 Ed Schonberg <schonberg@adacore.com>
2453 * exp_disp.adb (Build_Class_Wide_Check, Replace_Formals): When
2454 rewriting a class-wide condition, handle properly the case where the
2455 controlling argument of the operation to which the condition applies is
2456 an access to a tagged type, and the condition includes a dispatching
2457 call with an implicit dereference.
2459 2017-10-09 Bob Duff <duff@adacore.com>
2461 * exp_ch6.adb: (Make_Build_In_Place_Call_In_Object_Declaration): Remove
2462 the code at the end of this procedure that was setting the type of a
2463 class-wide object to the specific type returned by a function call.
2464 Treat this case as indefinite instead.
2466 2017-10-09 Ed Schonberg <schonberg@adacore.com>
2468 * sem_ch4.adb (Try_Class_Wide_Operation, Traverse_Homonyms):
2469 Suppress spurious ambiguity error when two traversals of the homonym
2470 chain (first directly, and then through an examination of relevant
2471 interfaces) retrieve the same operation, when other irrelevant homonyms
2472 of the operatioh are also present.
2474 2017-10-09 Ed Schonberg <schonberg@adacore.com>
2476 * sem_util.adb (Object_Access_Level): If the object is the return
2477 statement of an expression function, return the level of the function.
2478 This is relevant when the object involves an implicit conversion
2479 between access types and the expression function is a completion, which
2480 forces the analysis of the expression before rewriting it as a body, so
2481 that freeze nodes can appear in the proper scope.
2483 2017-10-09 Bob Duff <duff@adacore.com>
2485 * atree.adb: Make nnd apply to everything "interesting", including
2486 Rewrite. Remove rrd.
2488 2017-10-09 Javier Miranda <miranda@adacore.com>
2490 * exp_ch3.adb (Expand_N_Object_Declaration): Avoid never-ending loop
2491 processing the declaration of the dummy object internally created by
2492 Make_DT to compute the offset to the top of components referencing
2493 secondary dispatch tables.
2494 (Initialize_Tag): Do not initialize the offset-to-top field if it has
2495 been initialized initialized.
2496 * exp_disp.ads (Building_Static_Secondary_DT): New subprogram.
2497 * exp_disp.adb (Building_Static_Secondary_DT): New subprogram.
2498 (Make_DT): Create a dummy constant object if we can statically build
2499 secondary dispatch tables.
2500 (Make_Secondary_DT): For statically allocated secondary dispatch tables
2501 use the dummy object to compute the offset-to-top field value by means
2502 of the attribute 'Position.
2504 2017-10-09 Bob Duff <duff@adacore.com>
2506 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking
2507 code so if BIPAlloc is not passed in, it will likely raise
2508 Program_Error instead of cause miscellaneous chaos.
2509 (Is_Build_In_Place_Result_Type): Return False if not Expander_Active,
2510 as for the other Is_B-I-P... functions.
2511 * sem_aggr.adb (Resolve_Extension_Aggregate): For an extension
2512 aggregate whose ancestor part is a build-in-place call returning a
2513 nonlimited type, transform the assignment to the ancestor part to use a
2515 * sem_ch3.adb (Build_Itype_Reference): Handle the case where we're
2516 creating an Itype for a library unit entity.
2517 (Check_Initialization): Avoid spurious error message on
2518 internally-generated call.
2519 * sem_ch5.adb (Analyze_Assignment): Handle the case where the
2520 right-hand side is a build-in-place call. This didn't happen when b-i-p
2521 was only for limited types.
2522 * sem_ch6.adb (Create_Extra_Formals): Remove assumption that b-i-p
2523 implies >= Ada 2005.
2524 * sem_ch7.adb (Scan_Subprogram_Refs): Avoid traversing the same nodes
2526 * sem_util.adb (Next_Actual): Handle case of build-in-place call.

2552 actual for a formal package is an instantiation of a child unit, create
2553 a freeze node for the instance of the parent if it appears in the same
2554 scope and is not frozen yet.
2556 2017-10-09 Pierre-Marie de Rodat <derodat@adacore.com>
2558 * exp_atag.ads, libgnat/a-tags.adb, libgnat/a-tags.ads: Enhance
2559 in-source documentation for tagged types's Offset_To_Top.
2561 2017-10-09 Bob Duff <duff@adacore.com>
2563 * exp_ch3.adb (Build_Assignment): Parameter name N was somewhat
2564 confusing. Same for N_Loc. Remove assumption that b-i-p implies
2565 limited. This is for the case of a function call that occurs as the
2566 default for a record component.
2567 (Expand_N_Object_Declaration): Deal with the case where expansion has
2568 created an object declaration initialized with something like
2570 * exp_ch3.adb: Minor reformatting.
2572 2017-10-09 Ed Schonberg <schonberg@adacore.com>
2574 * exp_attr.adb (Expand_Attribute_Reference, case 'Valid): The prefix of
2575 the attribute is an object, but it may appear within a conversion. The
2576 object itself must be retrieved when generating the range test that
2577 implements the validity check on a scalar type.
2579 2017-10-05 Eric Botcazou <ebotcazou@adacore.com>
2582 * mingw32.h (_O_U8TEXT, _O_U16TEXT, _O_WTEXT): Delete.

2590 (time_t): Change from derived type to subtype.
2591 (timeval): Use suseconds_t for tv_usec.
2592 * libgnarl/s-osinte__x32.adb (To_Timespec): Remove use type clause.
2594 2017-10-02 Richard Sandiford <richard.sandiford@linaro.org>
2596 * gcc-interface/decl.c (annotate_value): Use wi::to_widest when
2597 handling the form (plus/mult (convert @0) @1).
2599 2017-09-29 Bob Duff <duff@adacore.com>
2601 * exp_ch6.adb (Expand_Call_Helper): Replace with code more similar to
2603 (Make_Build_In_Place_Call_In_Object_Declaration): Back out previous
2604 change. Set the Etype in the class-wide case. This fixes a regression
2605 in the libadalang test suite.
2607 2017-09-29 Joel Brobecker <brobecker@adacore.com>
2609 * doc/gnat_ugn/building_executable_programs_with_gnat.rst,

2623 uninitialized file descriptors.
2624 * osint.adb, osint.ads (Read_Source_File): Add extra parameter to
2625 return result of IO to encompass a read access failure in addition to a
2626 file-not-found error.

2632 and type conversions.
2633 (Expand_N_Extended_Return_Statement): Correct the computation of
2634 Func_Bod to allow for child units.
2635 (Expand_Simple_Function_Return): Remove assumption that b-i-p implies

2638 (Is_Build_In_Place_Result_Type): New function to accompany
2639 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
2640 sometimes we just have the type on our hands, not the function. For
2641 now, does the same thing as the old version, so build-in-place is
2642 disabled for nonlimited types, except that you can use -gnatd.9 to
2644 * exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
2645 accompany Is_Build_In_Place_Function and
2646 Is_Build_In_Place_Function_Call, because sometimes we just have the
2647 type on our hands, not the function.
2648 (Make_Build_In_Place_Call_In_...): Handle nonlimited build-in-place
2650 (Make_Build_In_Place_Call_In_Object_Declaration): Remove the
2651 questionable code at the end that was setting the Etype.
2652 * exp_aggr.adb (Is_Build_In_Place_Aggregate_Return): New function to
2653 determine whether "return (...agg...);" is returning from a
2654 build-in-place function.

2656 Remove assumption that b-i-p implies limited (initialization of
2657 In_Place_Expansion).
2658 (Build_Record_Aggr_Code): AI-287: fix comment; it can't be wrapped in
2659 an unchecked conversion. Add assertions.
2660 (Convert_Aggr_In_Object_Decl): Establish_Transient_Scope -- no need for
2661 secondary stack here, just because the type needs finalization. That
2663 (Convert_To_Assignments): Only set Unc_Decl if Nkind (N) = N_Aggregate.
2664 For "return (...agg...);" don't assume b-i-p implies limited.

2683 b-i-p implies >= Ada 2005.
2684 * exp_util.adb (Build_Allocate_Deallocate_Proc): Look at Storage_Pool
2685 (Expr), in case Pool_Id is not set.
2686 (Initialized_By_Aliased_BIP_Func_Call): Handle case where the call is
2687 qualified or converted.
2688 (Is_Secondary_Stack_BIP_Func_Call): Don't check if Nkind (Selector_Name
2689 (Param)) = N_Identifier; that's all it could be.
2690 * sinfo.ads: Comment fixes.
2691 * snames.ads-tmpl: Comment fixes.

2722 2017-09-29 Ed Schonberg <schonberg@adacore.com>
2724 * sem_ch6.adb (Analyze_Expression_Function): Do not emit freeze nodes
2725 for types in expression if the function is within a generic unit.
2726 * sem_res.adb (Resolve): In a generic context do not freeze an
2727 expression, unless it is an entity. This exception is solely for the
2728 purpose of detecting illegal uses of deferred constants in generic

2800 given set is highest in scope (not always the most prev).
2801 (Use_One_Package, Use_One_Type): Major cleanup and reorganization to
2802 handle the new chaining algorithm, also many changes related to
2803 redundant clauses. A new parameter has also been added to force
2804 installation to handle certain cases.

2831 (rather than relocating it) to avoid resolving a potentially malformed
2832 tree when the expression is resolved through an ASIS-specific call to

3674 2017-09-08 Yannick Moy <moy@adacore.com>
3676 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
3677 return the entity associated with the call.
3678 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
3679 Replace the internal Get_Function_Id with the new
3680 Sem_Aux.Get_Called_Entity.
3681 (Iterate_Call_Parameters): New
3682 procedure to iterate on formals and actuals at the same time.
3683 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
3684 Set SPARK_Mode from spec when set, for analysis
3685 of instance. Restore after analysis of instance.
3686 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
3687 set, for analysis of body instance. Restored automatically at
3688 the end of the subprogram.
3689 * gnat1drv.adb (Adjust_Global_Switches): Set
3690 Check_Validity_Of_Parameters to False in GNATprove mode.
3691 * opt.ads (Check_Validity_Of_Parameters): Document switch to
3694 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3696 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
3697 (New_Copy_Tree): ...there. Reset the hash tables only if they
3698 were used in the previous invocation.
3699 * s-htable.adb: Fix typo.
3701 2017-09-08 Bob Duff <duff@adacore.com>
3703 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
3705 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3707 * sem_aggr.adb: minor style fix.
3709 2017-09-08 Bob Duff <duff@adacore.com>
3711 * sprint.adb (Write_Corresponding_Source): Ignore if there is
3712 no current source file.
3713 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
3714 Print something helpful in case N is invalid.
3715 * sprint.ads: Minor comment fix.
3717 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3719 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
3722 2017-09-08 Bob Duff <duff@adacore.com>
3724 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
3725 Ada_2020, along the same lines as the other Ada version pragmas.
3727 2017-09-08 Gary Dismukes <dismukes@adacore.com>
3729 * sem_ch12.adb: Minor typo fixes and reformatting.
3731 2017-09-08 Yannick Moy <moy@adacore.com>
3733 * sem_aggr.adb (Resolve_Record_Aggregate):
3734 Rewrite bounds of aggregate subexpressions which may depend on
3735 discriminants of the enclosing aggregate.
3737 2017-09-08 Yannick Moy <moy@adacore.com>
3739 * sem_ch5.adb: Prevent assertion failure on illegal code.
3741 2017-09-08 Yannick Moy <moy@adacore.com>
3743 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
3744 calling Renamed_Entity on an entity which cannot be a renaming.
3746 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3748 * exp_aggr.adb: Add with & use clause for Urealp.
3749 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
3750 elementary types instead of just discrete types.
3751 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
3752 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
3753 Be prepared for the FP zero value in the memset case. Add small
3756 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3758 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
3761 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3763 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
3764 of New_Copy because the latter leaves the syntactic structure of
3765 the tree inconsistent (a child is accessible through two parents)
3766 and prevents proper replication of itypes by subsequent calls
3768 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
3769 New_Copy because the latter leaves the syntactic structure of the
3770 tree inconsistent (a child is accessible through two parents)
3771 and prevents proper replication of itypes by subsequent calls
3773 * sem_util.adb (In_Subtree): New routine.
3774 (New_Copy_Tree): Reimplemented.
3775 * sem_util.ads (In_Subtree): New routine.

3778 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3780 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
3781 for aspect Default_Value is a static scalar value, but it does
3782 not freeze the type. Yhis allows for subsequent representation
3783 clauses for the type.
3785 2017-09-08 Javier Miranda <miranda@adacore.com>
3787 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
3788 not add entries into the undefined reference table when we are
3789 compiling with errors ignored.
3791 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3793 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
3794 check if the instance is within an enclosing instance body. The
3795 formal package was legal in the enclosing generic, and is
3796 legal in the enclosing instantiation. This optimisation may be
3797 applicable elsewhere, and it also removes spurious errors that
3798 may arise with on-the-fly processing of instantiations that
3799 contain Inline_Always subprograms.
3801 2017-09-08 Vincent Celier <celier@adacore.com>
3803 * gnatcmd.adb: Disregard empty argument of GNAT driver.
3805 2017-09-08 Justin Squirek <squirek@adacore.com>
3807 * checks.adb (Insert_Valid_Check): Manually decorate
3808 the generated temporary for range valdity checks.
3810 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3812 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
3814 2017-09-08 Justin Squirek <squirek@adacore.com>
3816 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
3817 case to handle underscore flags.
3818 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
3819 new procedure to handle underscores.
3821 2017-09-08 Javier Miranda <miranda@adacore.com>
3823 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
3824 divisions with fixed point results to avoid generating twice
3825 the runtime check on divide by zero.
3826 * checks.adb (Apply_Divide_Checks): Ensure that operands are
3827 not evaluated twice (once for their runtime checks and once for
3828 their regular computation).
3830 2017-09-08 Yannick Moy <moy@adacore.com>
3832 * sem_prag.adb (Analyze_Part_Of): Add missing
3833 return statements after issuing errors. Add detection of
3834 out-of-order item and single concurrent type.

3941 New routine to read the Tag robustly.
3942 * exp_attr.adb (Input): Change the expansion of 'Input,
3943 in the class-wide case, to call String_Input_Tag instead of
3944 String_Input_Blk_IO.
3946 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3948 * s-rident.ads (Restriction_Id): reorder enum
3949 literals, so that Pure_Barriers is no longer in range of the
3950 Cunit_Boolean_Restrictions subtype.
3952 2017-09-08 Nicolas Roche <roche@adacore.com>
3954 * a-taster.ads, a-taster.adb: Move to libgnarl

3964 when the actual is a construct that involves a dereference of an
3965 expression that includes a formal of the enclosing subprogram,
3966 In such cases, the accessibility level of the actual is that of
3967 the corresponding formal, which is passed in as an additional
3968 actual in the outer call.
3970 2017-09-08 Bob Duff <duff@adacore.com>
3972 * exp_intr.adb (Add_Source_Info): Do not decode

3975 2017-09-08 Bob Duff <duff@adacore.com>
3977 * a-tags.adb (Internal_Tag): Unsuppress checks, so we get
3978 exceptions instead of crashes. Check for absurdly long strings
3979 and empty strings. Empty strings cause trouble because they can
3980 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
3981 be empty, which causes an array index out of bounds.
3982 * s-ststop.adb (Input): Unsuppress checks, so we get exceptions
3985 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3987 * sem_util.adb (Is_CCT_Instance): allow use in
3988 the context of protected types.

4007 not skip a loop coming from source which is rewritten into a loop.
4009 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4011 * freeze.adb (Wrap_Imported_Subprogram): Indicate that the
4012 wrapper has convention Ada, to prevent spurious warnings on

4042 * par-ch4.adb (P_Iterated_Component_Association): Place construct
4043 under -gnat2020 flag, given that it is a future feature of
4045 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
4046 defining identifier as referenced to prevent spurious warnings:
4047 corresponding loop is expanded into one or more loops whose
4048 variable has the same name, and the expression uses those names
4049 and not the original one.
4051 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4053 * sem_elab.adb (Check_A_Call): Do not consider
4054 references to internal variables for SPARK semantics.

4159 access to interface types. Remove also the accessibility check.
4161 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4163 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
4164 all the types that are referenced by the expression.
4165 (Analyze_Expression_Function): Call Freeze_Expr_Types for
4166 a completion instead of manually freezing the type of the
4168 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
4170 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4172 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
4173 New procedure, auxiliary to Expand_Pragma_Check, to handle
4174 references to the discriminants of a protected type within a
4175 precondition of a protected operation. This is needed because
4176 the original precondition has been analyzed in the context of
4177 the protected declaration, but in the body of the operation
4178 references to the discriminants have been replaved by references
4179 to the discriminants of the target object, and these references
4180 are only created when expanding the protected body.
4182 2017-09-08 Yannick Moy <moy@adacore.com>
4184 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
4187 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4189 * exp_attr.adb (Build_Record_VS_Func): If the record is an
4190 unchecked union, do not emit checks for its (non-existent)
4191 discriminants, or for variant parts that depend on them.

4195 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
4196 Find_Comparison_Type.Try_One_Interp): Add check for generic
4199 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4201 * sem_ch3.adb, layout.adb, layout.ads, exp_attr.adb, debug.adb,
4202 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
4203 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
4204 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
4205 remaining references to AAMP_On_Target.
4207 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4209 * style.adb: Fix typo.
4211 2017-09-08 Javier Miranda <miranda@adacore.com>
4213 * einfo.adb (Underlying_Type): Add missing support for class-wide
4214 types that come from the limited view.
4215 * exp_attr.adb (Attribute_Address): Check class-wide type
4216 interfaces using the underlying type to handle limited-withed
4218 (Attribute_Tag): Check class-wide type interfaces using
4219 the underlying type to handle limited-withed types.
4221 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4223 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
4224 over a subtype of a type with a static predicate, taking into
4225 account the predicate function of the parent type and the bounds
4226 given in the loop specification.
4227 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
4228 a loop specification that is a subtype indication whose type mark
4229 is a type with a static predicate, inherit predicate function,
4230 used to build case statement for rewritten loop.
4232 2017-09-08 Justin Squirek <squirek@adacore.com>
4234 * lib-load.adb: Modify printing of error message to exclude file
4237 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4239 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
4240 don't inline subprograms declared in both visible and private
4242 (In_Package_Spec): previously In_Package_Visible_Spec; now
4243 detects subprograms declared both in visible and private parts
4246 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4248 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
4249 the type is an anonymous array in an object declaration, whose
4250 component type has an invariant, use the object declaration
4251 as the insertion point for the invariant procedure, given that
4252 there is no explicit type declaration for an anonymous array type.
4254 2017-09-08 Bob Duff <duff@adacore.com>
4256 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.
4258 2017-09-08 Bob Duff <duff@adacore.com>

4271 Default_WCEM by default (i.e. if the encoding is not specified
4272 by the Form string).
4274 2017-09-08 Bob Duff <duff@adacore.com>
4276 * s-trasym.ads (Hexa_Traceback): If
4277 Suppress_Hex is True, print "..." instead of a hexadecimal
4279 * s-trasym.adb: Ignore No_Hex in this version.
4282 2017-09-08 Bob Duff <duff@adacore.com>
4284 * debug.adb: Minor reformatting.
4286 2017-09-08 Bob Duff <duff@adacore.com>
4288 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
4289 code so it doesn't trigger an "uninit var" warning.
4291 2017-09-08 Nicolas Roche <roche@adacore.com>
4293 * s-hibaen.ads: Remove obsolete file.
4295 2017-09-08 Arnaud Charlet <charlet@adacore.com>

4312 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4314 * debug.adb (dA): Adjust comment.
4315 * gnat1drv.adb (Gnat1drv): Likewise.
4316 * opt.ads (List_Representation_Info_Extended): New variable.
4317 * repinfo.adb (List_Record_Info): Split implementation into...
4318 (Compute_Max_Length): ...this. Recurse on records if requested.
4319 (List_Record_Layout): Likewise.
4320 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
4321 statement, accept '0' and set List_Representation_Info_Extended
4323 * usage.adb (Usage): Document new -gnatRe variant.
4325 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4327 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
4328 Do not save the given entity in the global variable Default_Pool
4329 if the pragma appears within a generic unit.
4331 2017-09-08 Bob Duff <duff@adacore.com>
4333 * errout.adb (Delete_Warning): Do not
4334 decrement Warnings_Treated_As_Errors. This is called before
4335 Warnings_Treated_As_Errors has been incremented to account for
4336 this warning. Decrementing it here can lead to negative values
4337 of Warnings_Treated_As_Errors, raising Constraint_Error in
4338 checks-on builds, and causing the compiler to return an error
4339 code in checks-off builds.
4341 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4343 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
4344 entities of named concurrent types as Ref_Id and not of anonymous
4345 concurrent objects (because callers already know when a conversion
4346 is necessary and can easily do it); also, do not expect protected
4347 types or protected objects as Context_Id (because no flow-related
4348 SPARK pragmas are attached there); reflect these changes in a
4349 more precise comment.
4351 2017-09-08 Olivier Hainque <hainque@adacore.com>
4353 * g-altive.ads: Add documentation.
4355 2017-09-08 Bob Duff <duff@adacore.com>
4357 * sem_util.ads, debug.adb: Minor comment fix.
4358 * erroutc.ads: Comment fix.
4360 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4362 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
4363 for compatibility of component types of formal and actual in an
4364 instantiation of a child unit, when the component type of the
4365 formal is itself a formal of an enclosing generic.
4367 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4369 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
4370 sem_prag.adb to make it available for GNATprove; for concurrent
4371 types replace custom scope climbing with Scope_Same_Or_Within; for
4372 single concurrent objects add scope climbing (with Scope_Within),
4373 which was not there (that's the primary semantic change of this
4374 commit); also, when comparing a single concurrent object with
4375 its corresponding concurrent type rely on equality of types,
4376 not of objects (because that's simpler to code).
4377 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
4378 (Analyze_Global_Item): adjust special-casing of references to the
4379 current instance of a concurrent unit in the Global contracts
4380 of task types and single tasks objects; similar for references
4381 in the protected operations and entries of protected types and
4382 single protected objects (in all these cases the current instance
4383 behaves as an implicit parameter and must not be mentioned in
4384 the Global contract).
4386 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4388 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
4389 function calls returning a record within a subprogram call,
4392 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4394 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
4395 name that designates the current instance of a child unit in its
4396 own body and appears as the prefix of a reference to an entity
4397 local to the child unit.
4398 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
4401 2017-09-08 Yannick Moy <moy@adacore.com>
4403 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that
4406 2017-09-08 Tristan Gingold <gingold@adacore.com>
4408 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
4409 warnings on internal units in configurable run time mode.
4411 2017-09-08 Bob Duff <duff@adacore.com>
4413 * sem_ch3.adb (Build_Derived_Private_Type): Inherit

4938 * sem_ch8.adb: Change Assert to be consistent with
4941 2017-09-06 Bob Duff <duff@adacore.com>
4943 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
4944 requested. Previously, the -do switch meant "run Elab_New and
4945 Elab_Old and use the order chosen by Elab_Old, possibly with
4946 debugging printouts comparing the two orders." Now it means
4947 "do not run Elab_New." This is of use if there are bugs that
4948 cause Elab_New to crash.
4949 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
4951 * ali.ads (Elab_Position): Change type to Nat, to avoid various
4954 2017-09-06 Arnaud Charlet <charlet@adacore.com>
4956 * sem_prag.adb (Check_Mode_Restriction_In_Enclosing_Context): Fix
4957 reference to SPARK RM.
4959 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4961 * layout.adb: Use SSU short hand consistently throughout the file.
4963 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4965 * freeze.adb (Freeze_Record_Type)
4966 <Sized_Component_Total_Round_RM_Size>: New local variable to
4967 accumulate the rounded RM_Size of components. Update it for
4968 every component whose RM_Size is statically known. Add missing
4969 guard to check that bit packing is really required before issuing
4970 the error about packing. Swap condition for clarity's sake.
4971 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.
4973 2017-09-06 Fedor Rybin <frybin@adacore.com>

4990 project manager sources.
4992 2017-09-06 Ed Schonberg <schonberg@adacore.com>
4994 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
4995 entity of a mutable type and the right-hand side is a conditional
4996 expression, resolve the alternatives of the conditional using
4997 the base type of the target entity, because the alternatives
4998 may have distinct subtypes. This is particularly relevant if
4999 the alternatives are aggregates.
5001 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5003 * checks.adb (Apply_Predicate_Check): If the expression is an
5004 aggregate that is the RHS of an assignment, apply the check to
5005 the LHS after the assignment, rather than to the aggregate. This
5006 is more efficient than creating a temporary for the aggregate,
5007 and prevents back-end crashes when the aggregate includes a
5008 dynamic "others' association.
5010 2017-09-06 Yannick Moy <moy@adacore.com>
5012 * sem_ch12.adb (Analyze_Instance_And_Renamings):
5013 Set variable to ignore SPARK_Mode in instance before the analysis
5014 of the generated package declaration.
5016 2017-09-06 Yannick Moy <moy@adacore.com>
5018 * sem_res.adb (Resolve_Call): Do not issue a
5019 message for calls inside expression function, unless body was
5020 seen and is candidate for inlining.
5022 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5024 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.
5025 * sem_ch3.adb (Analyze_Declarations): In a generic subprogram
5026 body. do not freeze the formals of the generic unit.
5028 2017-09-06 Gary Dismukes <dismukes@adacore.com>
5030 * errout.adb (Error_Msg): Separate the
5031 treatment for warning vs. style messages in inlinings and
5032 instantiations. Prevents blowups on calls to Warn_Insertion for
5033 style messages, which should not be called in that case because
5034 Warning_Msg_Char is not set.
5036 2017-09-06 Justin Squirek <squirek@adacore.com>
5038 * sem_prag.adb (Check_VFA_Conflicts): Created
5039 to group all Volatile_Full_Access checks relating to other
5040 representation pragmas (Mark_Component_Or_Object): Created
5041 to centeralize the flagging of attributes for the record type
5042 component case, a pragma applied individually to a component, and
5044 (Process_Atomic_Independent_Shared_Volatile):
5045 Add propagation of certain pragmas to record components and move
5046 evaluation of VFA checks
5048 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5050 * sem_prag.adb (Check_Postcondition_Use_In_Inlined_Subprogram):

5059 2017-09-06 Bob Duff <duff@adacore.com>
5061 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
5062 that is a proper body corresponding to a stub, we defer the
5063 adjustment of the sloc until after the correct adjustment has
5064 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
5065 the adjustment, because it will be outside the range in (the old,
5066 incorrect) S_Adjustment.
5067 * inline.adb: Use named notation for readability and uniformity.
5068 * sinput-l.adb: Minor improvements to debugging output printed
5070 * sinput-l.ads (Create_Instantiation_Source): Minor comment
5073 2017-09-06 Vincent Celier <celier@adacore.com>
5075 * make.adb: Do not invoke gprbuild for -bargs -P.
5077 2017-09-06 Sylvain Dailler <dailler@adacore.com>
5079 * sem_eval.adb (Compile_Time_Known_Value_Or_Aggr): Adding a
5080 case when Op is of kind N_Qualified_Expression. In this case,
5081 the function is called recursively on the subexpression like in
5083 * make.adb: Minor reformatting
5085 2017-09-06 Justin Squirek <squirek@adacore.com>
5087 * einfo.adb (Set_Linker_Section_Pragma): Modify
5088 Set_Linker_Section_Pragma to be consistant with the "getter"
5089 Linker_Section_Pragma.
5090 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
5091 checking for container loops so that the index cursor is not
5092 directly changable by the user with the use of E_Loop_Parameter.
5093 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.

5137 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
5138 Generate a freeze node for the actual of a formal package, if
5139 the actual is declared in the same unit and has a corresponding
5140 body, to prevent the current instance from being frozen before
5143 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>

5165 missing case of controlled generalized indexing.
5166 (Is_Source_Object): Use routine Strip to remove indirections.
5167 (Strip): New routine.
5169 2017-09-06 Bob Duff <duff@adacore.com>
5171 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
5172 we include the proper header. Otherwise, we just declare the necessary
5173 things from the capabilities library. This is so we can build on
5174 machines without that library, while still enabling that library.
5175 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
5176 simply return 0 if the library is not present, or not included
5179 2017-09-06 Pierre-Marie de Rodat <derodat@adacore.com>
5181 * exp_dbug.adb (Debug_Renaming_Declaration): Do not create an encoding

5192 has no parameter specification and no entry index, use the entry name
5193 as the end of the generated SCO statement.
5195 2017-09-06 Steve Baird <baird@adacore.com>
5197 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
5198 uses of 'Image and related attributes as having side effects in
5199 order to avoid replicating such uses.
5200 * pprint.ads (Expression_Image) Add new generic formal flag
5201 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
5202 (eventually) override the default.
5203 * pprint.adb (Expression_Image) If the new flag is set, then
5204 suppress the ".all" suffix when displaying a dereference whose
5205 prefix is a use of a value-capturing compiler temp of the sort
5206 generated by Expr_Util.Remove_Side_Effects .

5221 with slight modification from Is_Subp_Or_Entry_Inside_Protected,
5222 so that applies to any entity.
5224 2017-09-06 Yannick Moy <moy@adacore.com>
5226 * sem_ch3.adb (Derived_Type_Declaration): Use
5227 Incomplete_Or_Partial_View rather than local Find_Partial_View.
5229 2017-09-06 Javier Miranda <miranda@adacore.com>
5231 * g-catiio.ads, g-catiio.adb (Value): Extended to parse an UTC time
5234 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5236 * sem_dim.adb (Analyze_Dimension): In an instance, a type
5237 conversion takes its dimensions from the expression, not from
5239 (Dimensions_Of_Operand): Ditto.
5241 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5243 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to
5244 null procedures when GNAT coverage is used, so that their (empty)
5245 bodies are properly covered.

5249 * sem_ch13.adb (Resolve_Aspect_Expressions): If
5250 the entity is a type with discriminants, make the discriminants
5251 directly visible in aspect clauses.

5255 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are
5256 Universal_Real and the context is a floating-point type, resolve
5257 both operands to the target type.

5264 2017-09-06 Yannick Moy <moy@adacore.com>
5266 * freeze.adb (Check_Inherited_Conditions): Rewriting
5267 of inherited preconditions and postconditions should only occur
5268 in GNATprove mode, that is, when GNATprove_Mode is True, not to
5269 be confused with SPARK_Mode being On.
5271 2017-09-06 Yannick Moy <moy@adacore.com>

5284 on the procedure created to encapsulate the body.
5285 * sem_ch7.adb: Add with clause for GNAT.HTable.
5286 (Entity_Table_Size): New constant.
5287 (Entity_Hash): New function.
5288 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
5289 (Is_Subprogram_Ref): Rename into...
5290 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
5291 the table instead of bailing out on them. Scan the value of constants
5292 if it is not known at compile time.
5293 (Contains_Subprograms_Refs): Rename into...
5294 (Scan_Subprogram_Refs): ...this.
5295 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
5296 Is_Public flag on subprograms if they are not actually referenced.
5297 (Hide_Public_Entities): Beef up comment on the algorithm.
5298 Reset the table of subprograms on entry.
5300 2017-09-06 Yannick Moy <moy@adacore.com>

5341 of protected subprograms and entries.
5342 * sem_util.adb, sem_util.ads (Is_Subp_Or_Entry_Inside_Protected):
5343 New function to detect when a subprogram of entry is defined
5344 inside a protected object.

5350 * s-taprop-linux.adb (Get_Ceiling_Support): Update this to allow
5351 ceiling priorities if the current process has the CAP_SYS_NICE
5354 2017-09-06 Bob Duff <duff@adacore.com>
5356 * a-comlin.ads, a-comlin.adb (Argument): Move the constraint
5357 check back to the body, because SPARK is not yet ready for
5358 "or else raise Constraint_Error".
5360 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5362 * exp_ch6.adb (Expand_Call_Helper): Replace call to null
5363 procedure by a single null statement, after evaluating the

5380 * gnatcmd.adb: gnat ls -V -P... invokes gprls -V -P... The code
5381 from the Prj hierarchy has been removed from the GNAT driver.
5383 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5385 * sem_type.adb (Interface_Present_In_Ancestor): Within an
5386 expression function, or within a spec expression (default value,
5387 etc) a reference to an incomplete type is legal: legality of
5388 the operation will be checked when some related entity (type,
5389 object or subprogram) is frozen.
5391 2017-09-06 Gary Dismukes <dismukes@adacore.com>
5393 * exp_ch5.adb, s-diinio.ads, sem_ch4.adb, s-diflio.ads: Minor spelling

5404 * a-comlin.ads, a-comlin.adb (Argument): Simplify the code, now that
5405 we can use modern Ada in this package.
5406 * s-resfil.ads, s-resfil.adb, a-clrefi.ads, a-clrefi.adb:
5407 Move Ada.Command_Line.Response_File to System.Response_File,
5408 and make Ada.Command_Line.Response_File into a rename of
5409 System.Response_File. This is to avoid having gnatbind depend
5410 Ada.Command_Line, which would damage the bootstrap process now
5411 that Ada.Command_Line contains modern Ada (the raise expression).
5412 * gnatbind.adb: Avoid dependence on
5413 Ada.Command_Line. Depend on System.Response_File instead
5414 of Ada.Command_Line.Response_File. Change one call to
5415 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
5416 to Ada.Command_Line.Argument_Count to use Arg_Count.
5417 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
5419 2017-09-06 Bob Duff <duff@adacore.com>
5421 * frontend.adb (Frontend): Skip -gnatec=gnat.adc

5426 * exp_ch5.adb (Get_Default_Iterator): Replace
5427 "Assert(False)" with "return Iter", because if an iterable
5428 type is derived from a noniterable one, then we won't find an
5429 overriding or inherited default iterator.
5431 2017-09-06 Yannick Moy <moy@adacore.com>

5560 * sem_util.adb (Needs_One_Formal): The first formal of such a

6180 * exp_ch6.adb (Expand_Call_Helper): When locating the
6181 accessibility entity created for an access parameter, handle
6182 properly a reference to a formal of an enclosing subprogram. if
6183 the reference appears in an inherited class-wide condition, it
6184 is the rewriting of the reference in the ancestor expression,
6185 but the accessibility entity must be that of the current formal.
6187 2017-05-02 Javier Miranda <miranda@adacore.com>
6189 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.
6190 (Expand_N_Op_Add, Expand_N_Op_Divide, Expand_N_Op_Minus,

6224 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
6225 procedure body for a local (sub)type declaration within a
6226 predicate function. Invariant checks do not apply to these, and
6227 the expansion of the procedure will happen in the wrong scope,
6228 leading to misplaced freeze nodes.
6230 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6232 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
6233 to analyze generated actions. If the main unit is a body,

6236 2017-05-02 Arnaud Charlet <charlet@adacore.com>
6238 * einfo.adb (Declaration_Node): flip branches of
6239 an IF statement to avoid repeated negations in its condition;

6244 * sem_case.adb: Remove extra spaces in parameter declarations.
6246 2017-05-02 Justin Squirek <squirek@adacore.com>

6269 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
6270 Refine predicate for the case where the primitive operation
6271 is a renaming of equality. An overriding operation that is
6272 a user-defined renaming of predefined equality inherits its
6273 slot from the overridden operation. Otherwise it is treated
6274 as a predefined op and occupies the same predefined slot as
6275 equality. A call to it is transformed into a call to its alias,
6276 which is the predefined equality. A dispatching call thus uses
6277 the proper slot if operation is further inherited and called
6278 with class-wide arguments.
6280 2017-05-02 Justin Squirek <squirek@adacore.com>
6282 * errout.adb (Set_Msg_Text): Add a case to switch the message
6283 type when the character '[' is detected signifying a warning
6284 about a run-time exception.
6285 * opt.ads Add a new Warning_Mode value for new switch
6286 * switch-b.adb (Scan_Binder_Switches): Add case for the binder
6287 to handle new warning mode

6313 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6315 * exp_ch3.adb (Build_Initialization_Call): Generate a null
6316 statement if the initialization call is a null procedure, as
6317 can happen with a controlled type with no explicit Initialize
6318 procedure, or an array of such.
6319 * exp_ch7.adb (Process_Object_Declaration): For a type with
6320 controlled components that has a trivial Initialize procedure,
6321 insert declaration for finalization counter after object
6323 (Make_Deep_Array_Body, Build_Initialize_statements): Do not create
6324 finalization block and attendant declarations if component has
6325 a trivial Initialize procedure.
6326 (Make_Init_Call): Do not generate a call if controlled type has
6327 a trivial Initialize procedure.

6357 2017-05-02 Gary Dismukes <dismukes@adacore.com>
6359 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
6360 parameter Array_Comp to indicate the case of an array object
6361 with null-excluding components.
6362 * checks.adb (Null_Exclusion_Static_Checks):
6363 Call Compile_Time_Constraint_Error instead of
6364 Apply_Compile_Time_Constraint_Error in the component case. Also
6365 call that when Array_Comp is True, with an appropriate warning for
6366 the array component case. Only create an explicit initialization
6367 by null in the case of an object of a null-excluding access type
6368 (and no longer do that in the component case).
6369 * sem_ch3.adb (Check_Component): Add a Boolean parameter
6370 Array_Comp defaulted to False. Pass Empty for the Comp
6371 actual when calling Null_Exclusion_Static_Checks in the case
6372 where Comp_Decl matches Object_Decl, because we don't have a
6373 component in that case. In the case of an object or component
6374 of an array type, pass True for Array_Comp on the recursive call

6379 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
6380 compute the linux priority from the Ada priority. Call this everywhere
6381 required. In particular, the previous version was not doing this
6382 computation when setting the ceiling priority in various places. It
6383 was just converting to C.int, which results in a ceiling that is off
6386 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6388 * sem_ch3.adb: Comment predicate inheritance.
6390 2017-05-02 Tristan Gingold <gingold@adacore.com>

6405 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
6406 here from exp_ch9, to recognize objects whose creation requires
6407 dynamic allocation, so that the proper warning can be emitted
6408 when restriction No_Implicit_Heap_Allocation is in effect.
6409 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
6410 to emit proper warning when an object that requires dynamic
6411 allocation is declared.

6479 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6481 * exp_fixd.adb (Expand_Divide_Fixed_By_Fixed_Giving_Fixed):
6482 Simplify the expression for a fixed-fixed division to remove

6488 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
6490 2017-05-02 Bob Duff <duff@adacore.com>
6492 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6493 to find primitive ops, instead of using an Identifier that will
6494 later be looked up. This is necessary because these ops are not
6495 necessarily visible at all places where we need to call them.
6496 * exp_util.ads: Minor comment fix.
6498 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6500 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6501 references are fully conformant if they are both expansions
6502 of the discriminant of a protected type, within one of the
6503 protected operations. One occurrence may be expanded into a

6514 of non-initialized objects.
6515 * checks.adb, checks.ads (Null_Exclusion_Static_Checks): Added

6535 array components specially.
6537 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6539 * sem_ch8.adb (Premature_Usage): If the premature usage of
6540 an entity is as the expression in its own object decaration,
6541 rewrite the reference as Any_Id to prevent cascaded errors or
6542 compiler loops when such an entity is used in an address clause.
6544 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6546 * gcc-interface/decl.c (components_to_record): Add missing guard.

6551 Put back pending fields onto the regular list if the misalignment
6552 happens to cancel itself.
6554 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6556 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
6557 controlling actual in a prefixed call, preserve the original node
6558 information if the prefix itself has been rewritten, for ASIS use.
6560 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6562 * exp_ch6.adb (Insert_Post_Call_Actions):
6563 Code clean up. Insert the post-call actions after an enclosing
6564 procedure call when N denotes a function call and appears as an
6565 actual parameter in the procedure call.
6567 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6569 * freeze.adb (Check_Component_Storage_Order): If there is a clause
6570 for the component, also reject the attribute if the component
6571 doesn't end on a byte boundary and its scalar storage order is
6572 different from that of the enclosing record type.
6574 2017-04-28 Javier Miranda <miranda@adacore.com>
6576 * atree.ads (Info_Messages): Removed.

6606 2017-04-28 Bob Duff <duff@adacore.com>
6608 * sem_util.ads, sem_util.adb (Might_Raise): New function
6609 that replaces Is_Exception_Safe, but has the opposite
6610 sense. Is_Exception_Safe was missing various cases -- calls inside
6611 a pragma Debug, calls inside an 'if' or assignment statement,
6612 etc. Might_Raise now walks the entire subtree looking for things
6614 * exp_ch9.adb (Is_Exception_Safe): Remove.
6615 (Build_Protected_Subprogram_Body): Replace call to
6616 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
6617 constants where possible).
6618 * exp_ch7.adb: Rename Is_Protected_Body -->
6619 Is_Protected_Subp_Body. A protected_body is something different
6622 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>

6648 * sem_ch13.adb (Analyze_Aspect_Specifications, case
6649 Interrupt_Handler and Attach_Handler): Generate reference

6651 unreferenced entities. Previous scheme failed with style checks
6654 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6656 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6657 that follows an expression function must not be relocated to
6658 the generated body, because it applies to the code that follows.
6660 2017-04-28 Gary Dismukes <dismukes@adacore.com>
6662 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
6663 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
6664 code that might violate the more stringent checking for 'Access
6665 introduced in Ada 2005.
6667 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6669 * a-cforse.adb: minor style fix in comment.
6671 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6673 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
6674 initialize Block_Decls variable.
6675 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
6676 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.

6685 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
6687 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6689 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
6690 node between access types, freeze the designated type as well,
6691 so that dispatch table pointers are created in the proper scope,
6692 and not in the constructed body of the expression function.
6694 2017-04-28 Bob Duff <duff@adacore.com>
6696 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6697 value makes large compilations faster, but small compilations slower.
6699 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6701 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
6703 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6705 * erroutc.adb (Compilation_Errors): Do not consider info messages
6706 as suitable warnings when warnings must be treated as errors.

6719 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6721 * sem_res.adb (In_Instance_Code): New predicate in
6722 Valid_Conversion, to determine whether a type conversion appears
6723 as (or within) an actual for a formal object. Type conversions
6724 in instances are not rechecked in Valid_Conversion because
6725 visibility changes between generic location andi instance may
6726 lead to spurious errors, but conversions within an actual must be
6727 fully checked, and they are not fully resolved when pre-analyzing
6730 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6732 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
6733 New_Copy_Tree instead of Relocate_Node as any subsequent copies
6734 of the relocated node will have mangled Parent pointers.
6735 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
6736 tables used in conjunction with entity and itype replication.
6737 (Visit_Entity): Rewrite the restriction on which entities
6738 require duplication. The restriction now includes all types.

6772 (Restore_Warnings): Likewise.
6773 (Save_Warnings): Likewise.
6774 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
6775 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
6776 components_to_record.
6777 (gnu_field_to_gnat): New function.
6778 (warn_on_field_placement): Likewise.
6779 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
6780 parameters. Rename local variables and adjust recursive call.
6781 Rework final scan of the field list and implement warnings on the
6782 problematic placement of specific sorts of fields.
6784 2017-04-27 Bob Duff <duff@adacore.com>
6786 * errout.adb, exp_aggr.adb, exp_attr.adb, exp_code.adb, fname.adb,

6791 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
6792 For efficiency, cache results of Is_Internal_File_Name and
6793 Is_Predefined_File_Name in the Units table. This avoids a lot
6794 of repeated text processing.
6796 2017-04-27 Emmanuel Briot <briot@adacore.com>
6798 * g-comlin.adb (Sort_Sections): remove useless test.
6800 2017-04-27 Claire Dross <dross@adacore.com>
6802 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
6803 allow the use of regular equality over elements in contracts.
6804 (Formal_Model): Ghost package containing model functions that are
6805 used in subprogram contracts.
6806 (Current_To_Last): Removed, model functions should be used instead.
6807 (First_To_Previous): Removed, model functions should be used instead.
6808 (Strict_Equal): Removed, model functions should be used instead.
6809 (No_Overlap): Removed, model functions should be used instead.
6810 (Equivalent_Keys): Functions over cursors are removed. They were
6811 awkward with explicit container parameters.
6812 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
6813 allow the use of regular equality over elements in contracts.
6814 (Formal_Model): Ghost package containing model functions that

6823 * gnat1drv.adb: Code cleanup.
6825 2017-04-27 Ed Schonberg <schonberg@adacore.com>
6827 * exp_util.adb (Replace_Entity): The prefix of a 'Result
6828 attribute reference in a post- condition is the subprogram to
6829 which the condition applies. If the condition is inherited
6830 by a type extension, the prefix becomes a reference to the
6831 inherited operation, but there is no need to create a wrapper
6832 for this operation, because 'Result is expanded independently
6833 when elaborating the postconditions.
6835 2017-04-27 Bob Duff <duff@adacore.com>
6837 * sinput.adb: Minor code cleanup.
6838 * namet.adb (Append): Create faster versions of
6839 Append(String) and Append(Name_Id) by using slice assignment
6841 * sem_util.adb (In_Instance): Speed this up by removing
6842 unnecessary tests; Is_Generic_Instance is defined for all
6844 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
6845 Remove unused function.
6846 * alloc.ads (Nodes_Initial): Use a much larger value, because
6847 the compiler was spending a lot of time copying the nodes table
6848 when it grows. This number was chosen in 1996, so is rather out
6849 of date with current memory sizes. Anyway, it's virtual memory.
6850 Get rid of Orig_Nodes_...; use Node_... instead.
6851 * atree.adb (Lock): Do not release the Nodes tables; it's a
6853 Orig_Nodes_ ==> Nodes_
6854 * nlists.adb: Orig_Nodes_ ==> Nodes_
6855 * g-table.adb: Remove unused "with" clause.
6856 * g-table.ads, table.ads: Remove Big_Table_Type, which should
6857 not be used by clients.
6858 * g-dyntab.adb (Last_Allocated): New function
6859 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.
6861 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
6863 * sem_eval.adb (Subtypes_Statically_Compatible): Remove duplicated

6887 and selected components.

6899 of Expand_Dispatching_Call. If the denoted subprogram has a
6900 class-wide precondition, this is the only precondition that
6901 applies to the call, rather that the class-wide preconditions
6902 that may apply to the body that is executed. (This is specified
6905 2017-04-27 Yannick Moy <moy@adacore.com>
6907 * gnat1drv.adb (Adjust_Global_Switches): Issue
6908 a warning in GNATprove mode if the runtime library does not

7428 * a-cfdlli.adb, a-cfdlli.ads (Formal_Model): Adapt to
7429 modifications in functional containers.
7430 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
7431 to improve readablity. Subprograms are separated between basic
7432 operations, constructors and properties. Universally quantified
7433 formulas in contracts are factorized in independant functions
7434 with a name and a comment. Names of parameters are improved.
7436 2017-04-27 Gary Dismukes <dismukes@adacore.com>
7438 * exp_spark.adb, sem_elab.adb: Minor reformatting and typo fix.
7440 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7442 * sem_res.adb (Resolve_Type_Conversion): Do not
7443 install a predicate check here since this is already done during
7444 the expansion phase. Verify whether the operand satisfies the
7445 static predicate (if any) of the target type.
7446 * sem_ch3.adb (Analyze_Object_Declaration): Do
7447 not install a predicate check if the object is initialized by
7448 means of a type conversion because the conversion is subjected

7472 * gcc-interface/Make-lang.in: Add support for backend zcx exceptions
7473 in gnat1 and gnatbind.
7474 * gnat1, gnatbind: link with raise-gcc.o, a-exctra.o, s-addima.o,
7475 s-excmac.o, s-imgint.o, s-traceb.o, s-trasym.o, s-wchstw.o

7483 modifications in functional containers.
7484 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
7485 to improve readablity. Subprograms are separated between basic
7486 operations, constructors and properties. Universally quantified
7487 formulas in contracts are factorized in independant functions
7488 with a name and a comment. Names of parameters are improved.

7522 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7524 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
7525 the loop which detects potential enclosing transient scopes. The
7526 loop now terminates much earlier as transient scopes are bounded
7527 by packages and subprograms.
7529 2017-04-27 Claire Dross <dross@adacore.com>
7531 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to
7532 allow the use of regular equality over elements in contracts.
7533 (Cursor): Type is now public so that it can be used in
7535 (Formal_Model): Ghost package containing
7536 model functions that are used in subprogram contracts.
7537 (Current_To_Last): Removed, model functions should be used
7539 (First_To_Previous): Removed, model functions should
7541 (Strict_Equal): Removed, model functions
7542 should be used instead.
7543 (Append): Default parameter value
7544 replaced by new wrapper to allow more precise contracts.

7562 Default_Initial_Condition procedure of a type under the SPARK
7563 elaboration checks umbrella.
7565 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>

7586 * debug.adb Change the documentation of switch -gnatd.s.
7587 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
7588 to manage the secondary stack when an enclosing scope already
7589 performs this functionality (aka relaxed management). Switch
7590 -gnatd.s may be used to force strict management in which case
7591 the block will manage the secondary stack unconditionally. Add
7592 a guard to stop the traversal when encountering a package or a
7595 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7597 * sem_res.adb (Resolve_Call): Refine further the handling of
7598 limited views of return types in function calls. If the function
7599 that returns a limited view appears in the current unit,
7600 we do not replace its type by the non-limited view because
7601 this transformation is performed int the back-end. However,
7602 the type of the call itself must be the non-limited view, to
7603 prevent spurious resolution errors.
7605 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7607 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
7608 Removed, proposed implementation using generics for class-wide
7609 preconditions proved impractical.
7610 (Class_Wide_Clone): New attribute of subprogram. Designates
7611 subprogram created for primitive operations with class-wide
7612 pre/postconditions that contain calls to other primitives. The
7613 clone holds the body of the original primitive, but the
7614 pre/postonditions do not apply to it. The original body is
7615 rewritten as a wrapper for a call to the clone.
7616 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7617 the flag is set, no code for the corresponding pre/postconditions
7618 is inserted into its body.
7620 2017-04-27 Bob Duff <duff@adacore.com>
7622 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore

7636 (Remove): New function that removes an element from a sequence.
7637 (Insert): New function that adds anywhere in a sequence.

7666 private child of Ada.Containers used to implement all functional
7668 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
7669 child of Ada.Containers. It provides functional indefinite unbounded
7670 maps which can be used as high level models for specification
7672 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
7673 child of Ada.Containers. It provides functional indefinite unbounded
7674 sets which can be used as high level models for specification
7676 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
7677 child of Ada.Containers. It provides functional indefinite unbounded
7678 vectors which can be used as high level models for specification
7680 * Makefile.rtl: Add new packages.
7681 * impunit.adb: Add new packages.
7683 2017-04-27 Gary Dismukes <dismukes@adacore.com>
7685 * sem_ch4.adb: Minor reformatting.
7687 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7689 * sem_ch12.adb (Analyze_Associations): minor reformatting.
7690 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
7691 point type actual that has user-defined arithmetic primitives,
7692 when there is a previous actual for a formal package that defines
7693 a fixed-point type with the parent user-defined operator.
7695 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7697 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
7698 * sem_attr.adb (Resolve_Attribute): Generate a range check when
7699 the component type allows range checks.
7701 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7703 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
7704 corresponding declaration, because formal derived types are
7705 rewritten as private extensions.
7707 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7709 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
7710 dimensions of operands if node has been analyzed already, because
7711 previous analysis and dimension checking will have removed the
7712 dimension information from the operands.
7714 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7716 * debug.adb: Document the use of switch -gnatd.s.
7717 * einfo.ads Update the documentation on attribute
7718 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
7719 the uses of these attributes from certain entities.

7721 which determines whether the block should continue to manage
7722 the secondary stack.

7771 generating C code on complex case expressions.
7773 2017-04-25 Arnaud Charlet <charlet@adacore.com>
7775 * sem_prag.adb (Analyze_Pragma): Generate a warning instead
7776 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
7777 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
7778 Ada_2012 instead of Ada_2005 to be compatible with the above
7780 * bindgen.adb: Silence new warning on pragma Ada_95.
7782 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

7794 * prj-proc.adb, sem_util.adb, s-stposu.adb, sem_attr.adb, prj-conf.ads:
7795 Fix spelling mistakes.
7797 2017-04-25 Bob Duff <duff@adacore.com>
7799 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
7800 * sinput-p.adb: Use regular fat pointers, with bounds checking,
7801 for source buffers. Fix misc obscure bugs.
7802 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
7803 checking, for source buffers. Modify representation clause for
7804 Source_File_Record as appropriate. Move Source_File_Index_Table
7805 from spec to body, because it is not used outside the body.
7806 Move Set_Source_File_Index_Table into the private part, because
7807 it is used only in the body and in children. Use trickery to
7808 modify the dope in the generic instantiation case. It's ugly,
7809 but not as ugly as the previous method. Fix documentation.
7810 Remove obsolete code.
7811 * fname-sf.adb, targparm.adb: Fix misc out-of-bounds
7812 indexing in source buffers.

7826 expander is not active or when index/range checks are suppressed
7828 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
7829 Remove variants that include a Supress parameter. These routines
7830 are never used, and were introduced before the current scope-based
7831 check suppression method.
7833 2017-04-25 Vasiliy Fofanov <fofanov@adacore.com>

7853 is now carried out by Null_Status.
7854 (Null_Status): New routine.

7861 error on the return type of an expression function that is a
7862 completion, if the type is derived from a generic formal type.
7864 2017-04-25 Ed Schonberg <schonberg@adacore.com>

7881 errout.adb, sinput.adb, sinput.ads, cstand.adb, scn.adb,
7882 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
7883 the Internal_Source buffer. This removes the incorrect call to "="
7884 the customer noticed.
7885 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
7886 eventually need to eliminate them altogether. Or else get rid
7887 of zero-origin addressing.
7889 2017-04-25 Claire Dross <dross@adacore.com>
7891 * exp_util.ads (Expression_Contains_Primitives_Calls_Of): New

8432 * exp_ch4.adb (Expand_N_Op_Expon): Relocate left
8433 and right operands after performing the validity checks. Required
8434 because validity checks may remove side effects from the operands.
8436 2017-04-25 Javier Miranda <miranda@adacore.com>
8438 * exp_attr.adb (Attribute_Unrestricted_Access):
8439 Do not disable implicit type conversion. Required to generate

8455 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
8456 dereference is introduced for the object, and the object is
8457 overloaded, do not check whether it is aliased, because it may
8458 include an implicit dereference.
8459 * sem_type.adb (Disambiguate): If two interpretations are access
8460 attribute types with the same designated type keep either of
8461 them and do not report an ambiguity. A true ambiguity will be
8464 2017-04-25 Bob Duff <duff@adacore.com>
8466 * a-numeri.ads: Change the encoding of Greek letter Pi from
8467 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
8468 to indicate the encoding. We considered using a byte order mark
8469 (BOM), but that causes various trouble (misc software eats the
8470 BOM, if you have a patch with a BOM, then it's not at the start
8471 of the patch, so it's not a BOM, the BOM affects with-ing files,

8515 enforce legality rule on classwide preconditions inherited from
8516 both an ancestor and a progenitor (RM 6.1.1 (10-13).
8517 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
8518 subprogram need not be dispatching if it appears in a precondition
8519 for an abstract or null subprogram.
8521 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8523 * sem_ch10.adb: Minor typo fix.

8527 * gcc-interface/Makefile.in: Cleanup VxWorks targets.
8529 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>

8532 have a length which is a power of 2.
8533 (Is_Predefined_File_Name): Likewise. Adjust comment.
8535 2017-04-25 Bob Duff <duff@adacore.com>
8537 * exp_aggr.adb (Component_Count): Protect the
8538 arithmetic from attempting to convert a value >= 2**31 to Int,
8539 which would otherwise raise Constraint_Error.
8541 2017-04-25 Bob Duff <duff@adacore.com>
8543 * opt.ads (Locking_Policy): Fix incorrect documentation. The
8544 first character of the policy name is not unique.

8567 Save and restore the value of global flag
8568 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value

8570 the corresponding spec or the body must ignore all SPARK_Mode
8571 pragmas found within.
8572 (Analyze_Subprogram_Declaration): Mark
8573 the spec when it needs to ignore all SPARK_Mode pragmas found
8574 within to allow the body to infer this property in case it is
8575 instantiated or inlined later.
8576 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
8577 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
8578 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
8579 when the corresponding spec also ignored all SPARK_Mode pragmas
8581 (Analyze_Package_Declaration): Mark the spec when
8582 it needs to ignore all SPARK_Mode pragmas found within to allow
8583 the body to infer this property in case it is instantiated or
8585 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
8586 Save and restore the value of flag
8587 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
8588 formal spec when it needs to ignore all SPARK_Mode
8589 pragmas found within to allow the body to infer this
8590 property in case it is instantiated or inlined later.
8591 (Analyze_Package_Instantiation): Save and restore the value
8592 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
8593 the instance spec when it needs to ignore all SPARK_Mode

8612 Ignore_Pragma_SPARK_Mode.
8613 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
8614 all SPARK_Mode pragmas defined within yields mode "off".
8616 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8618 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.

8635 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8637 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
8638 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
8639 variable and set it to True whenever the main hash table is
8640 populated. Short- circuit the Assoc function if it is false
8641 and add associated guards.
8643 2017-04-25 Olivier Hainque <hainque@adacore.com>
8645 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
8646 specs without elaboration code that have an elaboration counter
8647 nevertheless, e.g. when compiled with -fpreserve-control-flow.
8648 * sem_ch10.adb (Analyze_Compilation_Unit):
8649 Set_Elaboration_Entity_Required when requested to preserve
8650 control flow, to ensure the unit elaboration is materialized at
8651 bind time, resulting in the inclusion of the unit object file
8652 in the executable closure at link time.
8654 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8656 * exp_dbug.adb: In Debug_Renaming_Declaration,
8657 when dealing with indexed component, accept to produce a renaming
8658 symbol when the index is an IN parameter or when it is a name
8659 defined in an outer scope.
8661 2017-04-25 Yannick Moy <moy@adacore.com>
8663 * errout.adb (Error_Msg): Adapt continuation
8664 message in instantiations and inlined bodies for info messages.
8666 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8668 * fname.adb (Has_Internal_Extension): Add pragma Inline.
8669 Use direct 4-character slice comparisons.
8671 pragma Inline. (Has_Suffix): Delete.
8672 (Is_Internal_File_Name):
8673 Test Is_Predefined_File_Name first.
8674 (Is_Predefined_File_Name):

8678 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8680 * checks.adb (Insert_Valid_Check): Code cleanup.
8681 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8682 (Expand_Actuals): Generate proper copy-back for a validation
8683 variable when it acts as the argument of a type conversion.
8684 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8685 predicate to operate on type qualifications.
8687 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8689 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8692 2017-04-25 Bob Duff <duff@adacore.com>
8694 * sem_prag.adb (No_Return): Give an error if the pragma applies
8695 to a body. Specialize the error for the specless body case,
8696 as is done for (e.g.) pragma Convention.
8697 * debug.adb: Add switch -gnatd.J to disable the above legality
8698 checks. This is mainly for use in our test suite, to avoid
8699 rewriting a lot of illegal (but working) code. It might also
8700 be useful to customers. Under this switch, if a pragma No_Return
8701 applies to a body, and the procedure raises an exception (as it
8702 should), the pragma has no effect. If the procedure does return,
8703 execution is erroneous.
8705 2017-04-25 Bob Duff <duff@adacore.com>
8707 * exp_ch6.adb (Expand_Actuals): This is the
8708 root of the problem. It took N as an 'in out' parameter, and in
8709 some cases, rewrote N, but then set N to Original_Node(N). So
8710 the node returned in N had no Parent. The caller continued
8711 processing of this orphaned node. In some cases that caused a
8712 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8713 and trips over the Empty Parent). The solution is to make N an
8714 'in' parameter. Instead of rewriting it, return the list of
8715 post-call actions, so the caller can do the rewriting later,
8716 after N has been fully processed.
8717 (Expand_Call_Helper): Move most of Expand_Call here. It has
8718 too many premature 'return' statements, and we want to do the
8719 rewriting on return.
8720 (Insert_Post_Call_Actions): New procedure to insert the post-call
8721 actions in the appropriate place. In the problematic case,
8722 that involves rewriting N as an Expression_With_Actions.
8723 (Expand_Call): Call the new procedures Expand_Call_Helper and
8724 Insert_Post_Call_Actions.
8726 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8728 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
8729 properly type derived from generic formal types, to handle
8730 properly modified version of ACATS 4.1B B611017.
8732 2017-04-25 Javier Miranda <miranda@adacore.com>
8734 * exp_unst.adb (Subp_Index): Adding missing
8735 support for renamings and functions that return a constrained
8736 array type (i.e. functions for which the frontend built a
8737 procedure with an extra out parameter).
8739 2017-04-25 Pascal Obry <obry@adacore.com>
8741 * s-string.adb: Minor code clean-up.
8743 2017-04-25 Bob Duff <duff@adacore.com>

8748 function for Non_Blocking_Wait_Process.
8750 2017-04-25 Bob Duff <duff@adacore.com>
8752 * prep.adb (Preprocess): Remove incorrect
8753 Assert. Current character can be ASCII.CR.
8755 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8757 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
8758 convention Stdcall, which has a number of exceptions. Convention
8759 is legal on a component declaration whose type is an anonymous
8760 access to subprogram.
8762 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8764 * sem_ch4.adb: sem_ch4.adb Various reformattings.
8765 (Try_One_Prefix_Interpretation): Use the base type when dealing
8766 with a subtype created for purposes of constraining a private
8767 type with discriminants.
8769 2017-04-25 Javier Miranda <miranda@adacore.com>

8773 dispatching primitives (Restore_Warnings): Restore warning on
8774 late dispatching primitives (Save_Warnings): Save warning on late
8775 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
8776 to enable/disable this warning.
8777 (WA_Warnings): Set warning on late dispatching primitives.
8778 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
8779 that its parent type has a private extension.
8780 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
8782 * usage.adb: Document -gnatw.j and -gnatw.J.
8784 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8786 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
8789 2017-04-25 Bob Duff <duff@adacore.com>
8791 * binde.adb (Validate): Do not pass dynamic strings
8792 to pragma Assert, because older compilers do not support that.
8794 2017-04-25 Bob Duff <duff@adacore.com>
8796 * s-fileio.adb (Close): When a temp file is
8797 closed, delete it and clean up its Temp_File_Record immediately,
8798 rather than waiting until later.
8799 (Temp_File_Record): Add File
8800 component, so Close can know which Temp_File_Record corresponds
8801 to the file being closed.
8802 (Delete): Don't delete temp files,
8803 because they are deleted by Close.
8804 (Open): Set the File component
8805 of Temp_File_Record. This requires moving the creation of the
8806 Temp_File_Record to the end, after the AFCB has been created.
8808 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8810 * checks.adb (Insert_Valid_Check): Do not generate
8811 a validity check when inside a generic.

8825 concerning inheritance of class-wide preconditions do not apply
8828 2017-04-25 Bob Duff <duff@adacore.com>
8830 * s-ficobl.ads: Minor comment fix.
8832 2017-04-25 Yannick Moy <moy@adacore.com>
8834 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
8835 conversions from float to integer in GNATprove mode.
8836 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
8837 to call Apply_Type_Conversion_Checks, so that range checks
8838 are properly positioned when needed on conversions, including
8839 when converting from float to integer. (Determine_Range): In
8840 GNATprove mode, take into account the possibility of conversion
8841 from float to integer.
8842 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
8843 check on conversions from fixed-point to integer, not anymore
8844 on conversions from floating-point to integer, when in GNATprove
8847 2017-04-25 Yannick Moy <moy@adacore.com>
8849 * checks.adb (Determine_Range_R): Special case type conversions
8850 from integer to float in order to get bounds in that case too.
8851 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
8852 mode, for computations involved in interval checking.

8866 * exp_attr.adb (Make_Range_Test): Add processing for validation
8867 variables to avoid extra reads and copies of the prefix.
8868 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
8869 variables in order to reflect any changes done in the variable
8870 back into the original object.
8871 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
8872 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

8880 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8882 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
8883 Analyze_Pre_Post_Condition, to implement the legality checks
8884 mandated by AI12-0131: Pre'Class shall not be specified for an
8885 overriding primitive subprogram of a tagged type T unless the
8886 Pre'Class aspect is specified for the corresponding primitive
8887 subprogram of some ancestor of T.
8889 2017-04-25 Bob Duff <duff@adacore.com>
8891 * sem_ch8.adb (Use_One_Type): If a use_type_clause
8892 is redundant, set its Used_Operations to empty. This is only
8893 necessary for use clauses that appear in the parent of a generic
8894 child unit, because those use clauses get reanalyzed when we
8895 instantiate the generic, and we don't want the Used_Operations
8896 carried over from the original context (where it was probably
8899 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8901 * exp_ch6.adb: Minor reformatting.

8914 * sem_ch8.adb (Find_Type): For an attribute reference
8915 'Class, if prefix type is synchronized and previous errors
8916 have suppressed the creation of the corresponding record type,
8917 create a spurious class-wide for the synchonized type itself,
8918 to catch other misuses of the attribute

8939 * exp_ch4.adb (Library_Level_Target): New function.
8940 (Expand_Concatenate): When optimization is enabled, also expand
8941 the operation out-of-line if the concatenation is present within
8942 the expression of the declaration of a library-level object and
8943 not only if it is the expression of the declaration.
8945 2017-04-25 Bob Duff <duff@adacore.com>
8947 * freeze.adb (Freeze_Object_Declaration): Do
8948 not Remove_Side_Effects if there is a pragma Linker_Section,
8949 because in that case we want static initialization in the
8950 appropriate section.
8952 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8954 * exp_dbug.adb: Minor rewording and reformatting.
8956 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8958 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
8959 handle the proposed changes to rules concerning potentially
8960 unevaluated expressions, to include selected components that
8961 do not depend on discriminants, and indexed components with

8983 renaming entity for debug information, mark the entity as needing debug
8984 info if it comes from sources.
8986 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8988 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
8989 restriction converning the use of 'Address where the prefix is

9007 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
9008 internal calls that appear in preconditions of protected
9009 operations, in default values for same, and in contract guards
9010 for contract cases in SPARK.
9012 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
9014 * a-numaux.ads: Fix description of a-numaux-darwin

9021 * a-numaux-x86.ads: Fix package description.
9022 * a-numaux-x86.adb (Is_Nan): Minor tweak.
9023 (Reduce): Adjust and complete description. Call Is_Nan instead of
9024 testing manually. Use an integer temporary to hold rounded value.
9025 * a-numaux-darwin.adb (Reduce): Likewise.
9026 (Is_Nan): New function.
9028 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9030 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
9031 on analysis of prefix whose type is a current instance of a
9032 synchronized type, but where the prefix itself is an entity that
9035 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9037 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
9038 the identity of callable entities therein, because they have been
9039 properly resolved, and prefixed calls may have been rewritten
9042 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
9044 * exp_ch3.adb (Build_Init_Statements): Convert
9045 the expression of the pragma/aspect Secondary_Stack_Size to
9046 internal type System.Parameters.Size_Type before assigning
9047 it to the Secondary_Stack_Size component of the task type's
9048 corresponding record.

9058 * s-osinte-freebsd.ads: Minor comment tweaks
9060 2017-04-25 Javier Miranda <miranda@adacore.com>
9062 * urealp.adb (UR_Write): Reverse previous patch
9063 adding documentation on why we generate multiplications instead
9064 of divisions (needed to avoid expressions whose computation with
9065 large numbers may cause division by 0).
9067 2017-04-25 Bob Duff <duff@adacore.com>
9069 * erroutc.adb (Set_Specific_Warning_Off,
9070 Set_Warnings_Mode_Off): Use the correct source file for
9071 Stop. Was using Current_Source_File, which is only valid during
9072 parsing. Current_Source_File will have a leftover value from
9073 whatever file happened to be parsed last, because of a with_clause
9076 2017-04-25 Bob Duff <duff@adacore.com>
9078 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
9079 to In_Predefined_Unit, but including GNAT units.
9080 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
9081 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
9082 because Should_Ignore_Pragma was not working reliably outside
9083 the parser, because Current_Source_File is not valid.
9084 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
9085 * par-prag.adb: Call Should_Ignore_Pragma_Par.

9122 Build_Invariant_Procedure_Body.
9123 (Build_Invariant_Procedure_Body):
9124 Remove refactored calls and integrated code from
9125 Add_Parent_Invariants and Add_Interface_Invariants.
9127 2017-04-25 Johannes Kanig <kanig@adacore.com>
9129 * errout.adb (Output_Messages): Adjust computation of total
9131 * erroutc.adb (Error_Msg): In statistics counts, deal
9132 correctly with informational messages that are not warnings.
9133 * errutil.adb (Finalize): adjust computation of total errors.

9144 2017-04-25 Justin Squirek <squirek@adacore.com>
9146 * sem_ch3.adb (Analyze_Declarations): Minor
9147 correction to comments, move out large conditional and scope
9148 traversal into a predicate.
9149 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
9152 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9154 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
9155 of prefix whose type is a current instance of a synchronized
9156 type. If the prefix is an object this is an external call (or
9157 requeue) that can only access public operations of the object. The
9158 previous predicate was too restrictive, and did not allow public
9159 protected operations, only task entries.
9161 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9163 * sem_ch5.adb, fname.adb: Minor reformatting.
9165 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9167 * einfo.adb (Is_Anonymous_Access_Type): New routine.
9168 * einfo.ads Update the placement of
9169 E_Anonymous_Access_Subprogram_Type along with all subtypes that
9171 (Is_Anonymous_Access_Type): New routine.
9172 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
9173 master for an access type subject to pragma No_Heap_Finalization.
9174 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
9175 allocated or deallocated does not finalization actions if the
9176 associated access type is subject to pragma No_Heap_Finalization.
9177 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
9178 * par-prag.adb Pragma No_Heap_Finalization does not need special
9179 processing from the parser.
9180 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
9181 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
9182 * sem_prag.adb Add an entry in table Sig_Flags for pragma
9183 No_Heap_Finalization.
9184 (Analyze_Pragma): Add processing for
9185 pragma No_Heap_Finalization. Update various error messages to
9186 use Duplication_Error.
9187 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
9188 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
9189 and corresponding pragma id.
9191 2017-04-25 Bob Duff <duff@adacore.com>
9193 * freeze.adb (Freeze_Record_Type): Use the
9194 underlying type of the component type to determine whether it's
9195 elementary. For representation clause purposes, a private type
9196 should behave the same as its full type.
9197 * fname.ads, fname.adb (Is_Predefined_File_Name):
9198 Make sure things like "system.ali" are recognized as predefined.
9200 2017-04-25 Javier Miranda <miranda@adacore.com>

9206 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
9207 element iterator when the name is an overloaded function call,
9208 one of whose interpretations yields an array.
9210 2017-04-25 Bob Duff <duff@adacore.com>
9212 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
9213 Is_Internal_Unit_Name): New functions for operating on unit
9214 names, as opposed to file names. There's some duplicated code
9215 with fname.adb, which is unfortunate, but it seems like we don't
9216 want to add dependencies here.
9217 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
9218 to Is_Predefined_Unit_Name; the former was wrong, because Uname
9219 is not a file name at all.
9220 * fname.ads, fname.adb: Document the fact that
9221 Is_Predefined_File_Name and Is_Internal_File_Name can be called
9222 for ALI files, and fix the code so it works properly for ALI
9223 files. E.g. these should return True for "system.ali".
9225 2017-04-25 Justin Squirek <squirek@adacore.com>
9227 * exp_util.adb (Add_Invariant): Removed,
9228 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
9229 and Add_Own_Invariant. (Add_Invariant_Check): Used
9230 for adding runtime checks from any kind of invariant.
9231 (Add_Inherited_Invariant): Generates invariant checks for
9232 class-wide invariants (Add_Interface_Invariants): Removed, code
9233 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):

9235 Removed, code moved to Build_Invariant_Procedure_Body
9236 (Build_Invariant_Procedure_Body): Add refactored calls
9237 and integrated code from Add_Parent_Invariants and
9238 Add_Interface_Invariants.
9239 (Process_Type): Removed, the
9240 relavant code was inlined into both Add_Own_Invariant and
9241 Add_Inherited_Invariant.
9243 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9245 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

9262 and Build_Invariant_Procedure_Declaration.
9263 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
9264 and Build_Invariant_Procedure_Declaration from exp_ch7
9265 and break-out Is_Untagged_Private_Derivation from
9266 Build_Invariant_Procedure_Body.
9267 (Replace_Type_References):
9268 Append an extra parameter to allow for dispatching replacements
9269 and add the corrasponding logic.
9270 (Type_Invariant): Remove
9271 Replace_Typ_Refs and replace its references with calls to
9272 Replace_Type_References.
9273 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
9275 2017-04-25 Bob Duff <duff@adacore.com>
9277 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
9278 that returns True when appropriate.
9279 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
9280 when compiling predefined files.
9281 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
9282 "gnat.adc" should not be considered a predefined file name.
9283 That required (or at least encouraged) a lot of cleanup of global
9284 variable usage. We shouldn't be communicating information via
9285 the global name buffer.
9286 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
9287 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

9292 * osint.adb (Find_File): Handle properly a request for a
9293 configuration file whose name is a directory.

9307 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
9308 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
9309 Add String_To_Name with no side effects.
9311 2017-04-25 Justin Squirek <squirek@adacore.com>
9313 * sem_ch3.adb (Analyze_Declarations): Add
9314 additional condition for edge case.

9318 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
9319 reserved words inside pragmas. This is necessary to allow the
9320 pragma name Interface to be used in pragma Ignore_Pragma.
9321 * par.adb: Minor comment fix.
9323 2017-04-25 Javier Miranda <miranda@adacore.com>
9325 * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.

9346 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
9347 the first pass over an assignment statement with target names,
9348 to prevent the generation of subtypes (such as discriminated
9349 record components)that may carry the target name outside of the
9350 tree for the assignment. The subtypes will be generated when
9351 the assignment is reanalyzed in full.
9352 (Analyze_Target_Name): Handle properly class-wide types.

9362 and resolve the triaged expression because all substitutions
9363 refer to the proper entities. Update the replacement of

9366 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
9367 are now only processed when freezing occurs. Build a body only

9384 properties of the private type to the full view in case the full
9385 view derives from a parent type and inherits a DIC pragma.
9386 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
9387 DIC pragma is placed at the top of a declarative region.
9389 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>
9391 * a-tasatt.adb: Complete previous change and use an unsigned
9392 int to avoid overflow checks.
9394 2017-04-25 Ed Schonberg <schonberg@adacore.com>

9397 the error message when the attribute reference is an actual in
9398 a call to a subprogram inherited from a generic formal type with
9399 unknown discriminants, which makes the subprogram and its formal
9400 parameters intrinsic (see RM 6.3.1 (8) and (13)).
9402 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9404 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

9409 * sem_attr.adb (Type_Key): Add code in the
9410 recursive Compute_Type_Key to protect against fetching the source
9411 code for Standard, in case a component of the type is declared
9412 in Standard. There was already code to do this for the original
9413 type, but not for its components.
9415 2017-04-25 Javier Miranda <miranda@adacore.com>
9417 * exp_ch3.adb (Build_Initialization_Call): Handle
9418 subtypes of private types when searching for the underlying full
9419 view of a private type.

9423 * sem_res.adb (Set_Mixed_Mode_Operand): A universal
9424 real conditional expression can appear in a fixed-type context

9432 appears in the context of a unit U2 compiled for instantiation
9433 or inlining purposes, the body of U1 needs to be compiled as well.
9434 * sem_prag.adb (Process_Inline): Set Body_Needed_For_Inlining if
9435 context is a package declaration.
9436 * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration,

10111 (Check_Dependency_Clause): Properly detect a match between two
10112 'Result attributes. Update the various post-match cases to use

10116 (Remove_Extra_Clauses): New routine.
10117 (Report_Extra_Clauses): Remove the detection of ... => null
10118 clauses as this is now done in Remove_Extra_Clauses.

10122 * sem_aggr.adb (Resolve_Array_Aggregate): In ASIS mode do not
10123 report on spurious overlaps between values involving a subtype
10124 with a static predicate, because the expansion of such a subtype
10125 into individual ranges in inhibited in ASIS mode.

10129 * sem_ch3.adb (Analyze_Declarations): Add detection

10157 to the expected type with the appropriate check flags set.
10158 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
10159 base type if the range is null. It may still be invalid if it
10160 is higher than the lower bound. This is checked later in the

10176 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
10177 an object declaration for an array type with a modular index type
10178 with the size of Long_Long_Integer. Special processing is needed
10179 in this case to compute reliably the size of the object, and
10180 eventually to raise Storage_Error, when wrap-around arithmetic
10181 might compute a meangingless size for the object.
10183 2017-01-23 Justin Squirek <squirek@adacore.com>
10185 * a-wtenau.adb, par-endh.adb, sem_prag.adb,

10190 * sem_res.adb (Resolve_Call): In the part of the code where
10191 it is deciding whether to turn the call into an indexed
10192 component, avoid doing so if the call is to an instance of
10193 Unchecked_Conversion. Otherwise, the compiler turns it into an
10194 indexed component, and resolution of that turns it back into a
10195 function call, and so on, resulting in infinite recursion.
10196 * sem_util.adb (Needs_One_Actual): If the first formal has a
10197 default, then return False.

10244 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
10245 must be treated as delayed aspect even if the expression is
10246 a literal, because the aspect affects the freezing and the
10247 elaboration of the object to which it applies.

10299 returns a limited view of a type and at the point of the call the
10300 function is not declared in the extended main unit then replace
10301 it with the non-limited view, which must be available. If the
10302 called function is in the extended main unit then no action is
10303 needed since the back-end handles this case.

10417 * sem_ch3.adb (Check_Non_Overridable_Aspects): An inherited
10418 aspect Implicit_Dereference can be inherited by a full view if
10419 the partial view has no discriminants, because there is no way
10420 to apply the aspect to the partial view.

10555 * sem_aggr.adb (Resolve_Aggregate): If the type is a string
10556 type, ie. a type whose component is a character type, and the
10557 aggregate is positional, do not convert into a string literal

10616 * sem_ch3.adb (Analyze_Declarations): Minor reformatting.
10617 (Build_Derived_Enumeration_Type): If the derived type inherits a
10618 dynamic predicate from its parent, the bounds of the type must
10619 freeze because an explicit constraint is constructed for the
10620 type and the corresponding range is elaborated now.

10658 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
10659 in case of generic formal discrete types, because it causes crashes in

10671 wrong since we just issued a warning message.
10672 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
10673 these variables to be of subtype Nat instead of Int, because
10674 they should never be negative.

10705 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10707 * sem_ch4.adb (Diagnose_Call): Improve error message when a
10708 selected component has a prefix that might be interpreted
10709 as a parameterless function call, but none of the candidate
10710 interpretations is parameterless, and there is a hidden homonym
10711 of the prefix that is a package.
10712 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
10713 interpreted as a parameterless function call and its analysis
10714 fails, do not call Analyze_Selected_Component.
10716 2017-01-19 Steve Baird <baird@adacore.com>
10718 * sem_util.ads: Add new Use_Full_View Boolean parameter to

10726 * lib-xref.ads (Traverse_Compilation_Unit): declaration moved
10727 to visible part of the package to allow re-use in GNATprove.
10728 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
10729 from repeated code of Traverse_Compilation_Unit.
10730 (Traverse_Declaration_Or_Statement): fixed detection of
10731 generic subprograms and packages; also, iteration over case
10732 statement alternatives rewritten to avoid testing if the first
10733 alternative is present (since it must be present due to Ada
10734 syntax restrictions).
10736 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
10738 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as

10748 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
10749 identifier nodes that do not come from source, to handle properly
10750 dimensionality check within an inlined body which inclddes both
10751 original operands and rewritten operands. This removes spurious
10752 dimensionality errors in the presence of front-end inlining,
10753 as well as in SPARK mode.
10755 2017-01-16 Jakub Jelinek <jakub@redhat.com>

10826 * sem_ch6.adb (Cloned_Expression): New subprogram.
10827 (Freeze_Expr_Types): Complete previous patch since the expression
10828 of an expression-function may have iterators and loops with
10829 defining identifiers which, as part of the preanalysis of the
10830 expression, may be left decorated with itypes that will not be
10831 available in the tree passed to the backend.
10833 2017-01-13 Ed Schonberg <schonberg@adacore.com>

10848 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
10850 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
10851 Ensure that the input body is a subprogram body before trying to
10852 determine whether it denoted an expression function. Note that
10853 subprogram body stubs cannot denote expression functions.

10871 2017-01-13 Bob Duff <duff@adacore.com>
10873 * binde.adb (Elab_New): New elaboration order algorithm
10874 that is expected to cause fewer ABE issues. This is a work in
10875 progress. The new algorithm is currently disabled, and can be
10876 enable by the -dp switch, or by modifying the Do_Old and Do_New
10877 etc. flags and rebuilding. Experimental code is included to
10878 compare the results of the old and new algorithms.
10879 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
10880 can have multiple of these tables, so the old and new algorithms
10882 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
10883 parameter of type array. This avoids the global variable, and
10884 allows bounds checking (which is normally defeated by the tables
10885 packages). It also ensures that the Elab_Order is read-only
10887 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
10888 subprograms that need it, as above.
10889 * debug.adb: Document new -dp switch. Modify doc of old -do

10895 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10897 * sem_ch6.adb (Analyze_Expression_Function): If the expression
10898 function is a completion, all entities referenced in the
10899 expression are frozen. As a consequence, a reference to an
10900 uncompleted private type from an enclosing scope is illegal.

10931 the legality of An others clause applies as well to a choice in
10932 an Iterated_component_ association.
10933 (Resolve_Iterated_Component_Association): An others choice
10935 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An

10968 of the original association. Generate a loop even for a single
10969 component choice, in order to make loop parameter visible in
10971 (Flatten): An Iterated_Component_Association is not static.

11019 False in this case.
11020 * sprint.adb (Sprint_Node): An Iterated_Component_Association
11021 has a Discrete_Choices list, as specified in the RM. A
11022 Component_Association for aggregate uses instead a Choices list.

11037 Analyze_Declarations, to analyze and resolve the expressions of
11038 aspect specifications in the current declarative list, so that

11043 original expression, to suppress cascaded errors when expression
11044 has been constant-folded.

11058 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
11059 when not applicable due to actual requiring type conversion
11060 with possible check but no temporary value can be copied for
