6
7 2018-05-30 Piotr Trojanek <trojanek@adacore.com>

10
11 2018-05-30 Hristian Kirtchev <kirtchev@adacore.com>
12
13 * sem_util.adb (Is_Atomic_Object): Cleaned up. Split the entity logic
14 in a separate routine.
15 (Is_Atomic_Object_Entity): New routine.
16 (Is_Atomic_Prefix): Cleaned up.
17 (Is_Synchronized_Object): Check that the object is atomic, or its type
18 is atomic.
19 (Object_Has_Atomic_Components): Removed.
20 * sem_util.ads (Is_Atomic_Object): Reword the comment on usage.
21 (Is_Atomic_Object_Entity): New routine.
22
23 2018-05-30 Ed Schonberg <schonberg@adacore.com>
24
25 * sem_ch3.adb (Access_Subprogram_Declaration): The flag
26 Needs_Activation_Record is only needed on a subprogram type, not on a
27 pointer to such.
28 * sem_res.adb (Resolve_Selected_Component): If the context type and the
29 component type are anonymous access to subprograms, use the component
30 type to obtain the proper value of Needs_Activation_Record flag for the
31 expression.
32
33 2018-05-30 Eric Botcazou <ebotcazou@adacore.com>
34
35 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>: Add
36 comment about the memset case.
37
38 2018-05-30 Bob Duff <duff@adacore.com>
39
40 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
41 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
42 We need to analyze it as part of analyzing the block, so that if the
43 call to Element that initializes Elmt_Decl returns on the secondary
44 stack, the block will ss_mark/ss_release. This block is inside the
45 loop; we don't want to leak memory until the loop exits. The purpose
46 of analyzing Elmt_Decl first was to catch the error of modifying it,
47 which is illegal because it's a loop parameter. The above causes us to
48 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
49 it on the Element entity, so we end up with an E_Variable node with the
50 flag set.
51 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
52 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
53 parameter not allowed" error if Is_Loop_Parameter.
54 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
55 trigger the call to Diagnose_Non_Variable_Lhs.
56
57 2018-05-30 Arnaud Charlet <charlet@adacore.com>
58
59 * checks.adb (Apply_Scalar_Range_Check):
60 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
61 range values for System.Priority in CodePeer mode since the actual
62 target compiler may provide a wider range.
63
64 2018-05-30 Ed Schonberg <schonberg@adacore.com>
65
66 * exp_unst.adb: Search specification of main unit as well, for
67 unnesting.
68
69 2018-05-30 Ed Schonberg <schonberg@adacore.com>
70
71 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
72 a package body that is a compilation unit may contain blocks that
73 declare local subprograms. In Subprogram_Unnesting Mode such
74 subprograms must be handled as nested inside the (implicit) elaboration
75 procedure that executes that statement part. To handle properly uplevel
76 references we construct that subprogram explicitly, to contain blocks
77 and inner subprograms, The statement part of the compilation unit
78 becomes a call to this subprogram. This is only done if blocks are
79 present in the statement list of the body.
80
81 2018-05-30 Bob Duff <duff@adacore.com>
82
83 * exp_ch7.adb: Minor comment fix.
84
85 2018-05-30 Ed Schonberg <schonberg@adacore.com>
86
87 * exp_unst.adb (Visit_Node): Handle properly subprogram instantiations
88 that have no corresponding body and appear as attributes of the
89 corresponding wrapper package declaration.
90 (Register_Subprogram): New subprogram, used for subprogram bodies and
91 for subprogram instantiations to enter callable entity into Subp table.
92
93 2018-05-30 Hristian Kirtchev <kirtchev@adacore.com>
94
95 * libgnat/s-secsta.adb: Reimplement the secondary stack support.
96 * libgnat/s-secsta.ads: Update the documentation of all routines in the
97 public part of the package. Reimplement the private part of the
98 package to account for the new secondary stack structure. Add types
99 and subprograms for testing purposes. Add several documentation
100 sections.
101
102 2018-05-30 Hristian Kirtchev <kirtchev@adacore.com>
103
104 * exp_aggr.adb, exp_ch3.adb, exp_ch4.adb, exp_ch7.adb, exp_unst.adb,

110
111 * gcc-interface/Makefile.in: Move special flags for Ada runtime files
112 from here...
113 * Makefile.rtl: ... to here. Update comments. Protect call to
114 "GCC_FOR_TARGET" in case target_os isn't defined.
115
116 2018-05-30 Arnaud Charlet <charlet@adacore.com>
117

123
124 * doc/gnat_ugn/building_executable_programs_with_gnat.rst (Alphabetical
125 List of All Switches): Replace "modules" with "units".
126 (Subprogram Inlining Control): Likewise.
127 * gnat_ugn.texi: Regenerate.
128 * usage.adb (Usage): Fix description of -gnatn switch.

137 the finalizer procedure in the At_End handler, for use in LLVM
138 generation.
139
140 2018-05-29 Javier Miranda <miranda@adacore.com>
141
142 * exp_ch4.adb (Expand_N_Op_Eq, Expand_Composite_Equality): Use the new
143 subprogram Inherits_From_Tagged_Full_View to identify more reliably
144 untagged private types completed with a derivation of an untagged
145 private whose full view is a tagged type.
146 * sem_util.ads, sem_util.adb (Inherits_From_Tagged_Full_View): New
147 subprogram.
148 (Collect_Primitive_Operations): Handle untagged private types completed
149 with a derivation of an untagged private type whose full view is a
150 tagged type. In such case, collecting the list of primitives we may
151 find two equality primitives: one associated with the untagged private
152 and another associated with the ultimate tagged type (and we must
153 remove from the returned list this latter one).
154
155 2018-05-29 Ed Schonberg <schonberg@adacore.com>
156
157 * exp_unst.adb (Visit_Node): Handle statement sequences that include an
158 At_End handler.

163
164 2018-05-29 Ed Schonberg <schonberg@adacore.com>
165
166 * exp_ch6.adb (Expand_N_Subprogram_Body): Do not generate push/pop for
167 exceptions if subprogram unnesting is in effect, because these branch
168 nodes are relevant only in the presence of nested subprograms.
169
170 2018-05-29 Ed Schonberg <schonberg@adacore.com>
171
172 * libgnat/s-fatgen.adb (Succ, Pred): Raise Constraint_Error
173 unconditionally when applied to the largest positive (resp. largest
174 negative) value of a floating-point type.
175
176 2018-05-29 Ed Schonberg <schonberg@adacore.com>
177
178 * einfo.ads, einfo.adb: Clarify use of Activation_Record_Component:
179 discriminants and exceptions are never components of such. The flag
180 Needs_Activation_Record is set on subprogram types, not on access to
181 them.
182
183 2018-05-29 Ed Schonberg <schonberg@adacore.com>
184
185 * sem_ch3.adb: Set scope of component of subtype.
186
187 2018-05-29 Ed Schonberg <schonberg@adacore.com>
188
189 * exp_unst.adb (Visit_Node): Exclude selected components whose prefix
190 carry no type. Such selected components appear in unit names that are
191 child units, both in the specification and possibly in an end label for
192 the unit, and they do not contain any relevant uplevel references.
193
194 2018-05-29 Arnaud Charlet <charlet@adacore.com>
195
196 * libgnat/a-calend.ads, libgnat/a-calend.adb (Epoch_Offset): Make it a

211
212 * vx_crtbegin.inc: Use a consistent naming convention for the
213 registration/deregistration functions across RTP or kernel. Remove the
214 ctor/dtor attribute setting based on RTP/kernel, expect the optional
215 attribute extension to be provided by includers instead.
216 * vx_crtbegin.c: Mere inclusion of vx_crtbegin.inc with empty attribute
217 extension for the registration/deregistration functions.
218 * vx_crtbegin_attr.c: New file. Include vx_crtbegin.inc with explicit

328 2018-05-29 Arnaud Charlet <charlet@adacore.com>
329
330 * lib-writ.adb (Write_ALI): Do not use new function from s-casuti yet.
331 This breaks build of cross compilers with older versions of GNAT, so
332 better avoid it.
333
334 2018-05-29 Doug Rupp <rupp@adacore.com>
335
336 * libgnarl/s-taprop.ads (Monotonic_Clock): Refine documentation to

382
383 2018-05-28 Ed Schonberg <schonberg@adacore.com>
384
385 * exp_unst.adb (Visit_Node): For indexed components and attribute
386 references, examine index expressions or associated expressions as well
387 to record uplevel references.
388 (Vist_Node): For function and procedure calls, if a formal is an
389 unconstrained array and the actual is constrained, check whether bounds
390 of actual have uplevel references.
391
392 2018-05-28 Ed Schonberg <schonberg@adacore.com>
393
394 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
395 they can appear as components of activation records.
396 * exp_unst.adb (Visit_Node): A reference to an exception may be an
397 uplevel reference.
398
399 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
400

402 depends on a discriminant manually instead of using the predicate
403 Size_Depends_On_Discriminant in the array type case.
404
405 2018-05-28 Ed Schonberg <schonberg@adacore.com>
406
407 * exp_unst.adb (Check_Static_Type): For a record subtype, check
408 discriminant constraints as well.
409 (Visit_Node): For a selected component, check type of prefix, as is
410 done for indexed components and slices.
411
412 2018-05-28 Javier Miranda <miranda@adacore.com>
413
414 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
415 value when converting a float value to a fixed-point value. This is
416 required for CCG because it handles fixed-point types by means of
417 unsigned integer type variables. The range check is now performed using
418 the integer value stored in this temporary.
419
420 2018-05-28 Yannick Moy <moy@adacore.com>
421
422 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

439
440 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
441
442 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
443 component type, do not expand array equality using the unconstrained
444 base type, except for the case where the bounds of the type depend on a
445 discriminant.
446
447 2018-05-28 Ed Schonberg <schonberg@adacore.com>
448
449 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
450 access-to-subprogram types, to indicate that an indirect call through
451 such a type requires an activation record when compiling for LLVM.
452 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
453
454 2018-05-28 Ed Schonberg <schonberg@adacore.com>
455
456 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
457 when bounds of fixed type are static, to remove some spuerfluous
458 implicit conversions and provide an accurate result when converting
459 back and forth between the fixed point type and a floating point type.
460
461 2018-05-28 Ed Schonberg <schonberg@adacore.com>
462
463 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
464 activation records.
465
466 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
467
468 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
469 replaced, if any; all callers changed.
470 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
471 constant with private view so we take the address of that entity.
472 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
473 any; all callers changed. Handle N_Indexed_Component like
474 N_Attribute_Reference. Add N_Type_Conversion case.
475 (Visit_Node): Indexed references can be uplevel if the type isn't
476 static.
477 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
478 been relocated, set first_named pointer in original node as well.
479
480 2018-05-28 Ed Schonberg <schonberg@adacore.com>
481
482 * exp_aggr.adb (Flatten): Copy tree of expression in a component
483 association with a range or a set of discrete choices, rather than
484 relocating the node. This avoids inconsistencies in the tree when
485 handling nested subprograms with uplevel references for LLVM.
486
487 2018-05-28 Arnaud Charlet <charlet@adacore.com>
488
489 * exp_util.adb (Possible_Bit_Aligned_Component): Always return False in

515 * exp_ch3.adb: Minor reformatting
516
517 2018-05-28 Justin Squirek <squirek@adacore.com>
518
519 * exp_ch3.adb
520 (Build_Initialization_Call): Add logic to pass the appropriate actual to match
521 new formal.
522 (Init_Formals): Add new formal *_skip_null_excluding_check
523 * exp_util.adb, exp_util.ads
524 (Enclosing_Init_Proc): Added to fetch the enclosing Init_Proc from the current
525 scope.
526 (Inside_Init_Proc): Refactored to use Enclosing_Init_Proc
527 (Needs_Conditional_Null_Excluding_Check): Added to factorize the predicate
528 used to determine how to generate an Init_Proc for a given type.
529 (Needs_Constant_Address): Minor reformatting

539
540 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
541 the declarations of single concurrent types because they fall in the
542 category of full type and object declarations.

545
546 * repinfo.adb (Compute_Max_Length): Skip _Parent component.
547 (List_Record_Layout): Likewise.
548
549 2018-05-28 Ed Schonberg <schonberg@adacore.com>
550
551 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
552 includes a call to function to which it applies. This may mean an
553 omission of an attribute reference 'Result, in particular if the
554 function is pqrameterless.
555
556 2018-05-28 Justin Squirek <squirek@adacore.com>
557
558 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the
559 misresolved package name is not a case of mistaken identity.
560
561 2018-05-28 Yannick Moy <moy@adacore.com>
562
563 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
564 GNATprove mode, as the order of resolution (low then high) means that
565 all the information is not available when resolving the low bound the
566 first time.
567

578 (List_Type_Info): Do not start with a blank line.
579
580 2018-05-25 Nicolas Roche <roche@adacore.com>
581
582 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
583 that the result will be either -infinite or +infinite.
584
585 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
586
587 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
588 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
589 Expand range of type to match the address space of the target.
590 (Task_Storage_Size): Remove unused type.
591
592 2018-05-25 Ed Schonberg <schonberg@adacore.com>
593
594 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
595 of a fixed point type and the parent is a multiplying operation,
596 resolve the operand with its own type because the context will impose a
597 resulting type on the result of the multiplication by means of
598 approriate conversion.
599
600 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
601
602 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
603 the in-place initialization aggregate created for pragmas
604 Initialize_Scalars or Normalize_Scalars is performed with checks
605 suppressed.
606

608
609 * exp_aggr.adb (Convert_To_Positional): Bump default for

614
615 2018-05-25 Javier Miranda <miranda@adacore.com>
616
617 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
618 test when the left operand is a class-wide interface and the right
619 operand is not a class-wide type.
620 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
621 left operand.
622
623 2018-05-25 Ed Schonberg <schonberg@adacore.com>
624
625 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
626 in an others clause to prevent visibility issues with the generated
627 loop variable.
628 (Component_OK_For_Backend): Return false for a quantified expression.
629 (Check_Static_Component): Ditto.
630
631 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
632
633 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
634 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
635 into three distring cases rather than in one loop which attempts to
636 handle all three cases. This rewrite eliminates an issue where the last
637 frame of the stack cannot be freed, thus causing the memory range of a
638 new frame to approach the overflow point of the memory index type.
639 Since the overflow is logically treated as a
640 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
641 (SS_Allocate_Static): New routine. The routine factorizes the static
642 secondary stack-related code from the former SS_Allocate.
643
644 2018-05-25 Sergey Rybin <rybin@adacore.com>
645
646 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
647 option for gnatelim.
648
649 2018-05-25 Ed Schonberg <schonberg@adacore.com>
650
651 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
652 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
653 is created when the proper body of the stub is analyzed.
654 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
655 is the proper body of a subunit, the cloned body must be inserted in
656 the declarative list that contains the stub.
657
658 2018-05-25 Justin Squirek <squirek@adacore.com>
659
660 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
661 generate code for 6.5(8-10) so that we don't get an assertion error
662 when dealing with an incomplete return type.
663
664 2018-05-25 Arnaud Charlet <charlet@adacore.com>
665
666 * pprint.adb (Expression_Name): Strip too long expressions to avoid
667 carrying very large strings.

685 assertions.
686
687 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>

690 pprint.adb, sem_ch12.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
691 Minor reformatting.
692
693 2018-05-25 Ed Schonberg <schonberg@adacore.com>
694
695 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
696 Validate_Derived_Type_Instance, to verify that all interfaces
697 implemented by the formal type are also implemented by the actual. The
698 verification is complicated when an interface of the formal is declared
699 in a generic unit and the actual is declared in an instance of it.
700 There is currently no mechanism to relate an interface declared within
701 a generic to the corresponding interface in an instance, so we must
702 traverse the list of interfaces of the actual, looking for a name
703 match, and verifying that that interface is declared in an instance.
704
705 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
706
707 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
708 assertions; replace function versions of Next_Formal/Next_Actual with
709 their procedural versions (which are more concise).

743 boolean type with convention C.
744 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
745 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable
746 FOREIGN and use it throughout the function.

770 prefixes of array attributes, to prefixes that are entity names whose
771 type is constrained.
772 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
773 subprogram, as itype created for loops in pre/postcondition may appear
774 in loops at the library level.
775
776 2018-05-25 Ed Schonberg <schonberg@adacore.com>
777
778 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
779 declaration is inserted into the tree and analyzed at that point, so
780 should not be reinserted when the body is constructed. Inside a
781 generic, ensure that the body is not inserted twice in the tree.
782
783 2018-05-25 Yannick Moy <moy@adacore.com>
784
785 * sem_prag.adb (Check_Grouping): Modify test to ignore statements and

798
799 2018-05-24 Eric Botcazou <ebotcazou@adacore.com>
800
801 * fe.h (Set_Normalized_First_Bit): Declare.
802 (Set_Normalized_Position): Likewise.
803 * repinfo.adb (List_Record_Layout): Do not use irregular output for a
804 variable position. Fix minor spacing issue.
805 * gcc-interface/decl.c (annotate_rep): If a field has a variable
806 offset, compute the normalized position and annotate it in addition to
807 the bit offset.
808

859
860 * sem_ch8.adb (Analyze_Use_Type): Do not assign the Prev_Use_Clause
861 link to a use_type clause if this would cause an infinite loop in the

1273 iteration of an Ada2012 loop is performed to determine the type of the
1274 domain, but full analysis is performed once the loop is rewritten as a

1276 must also suppress the generation of freeze nodes, which may otherwise
1277 appear in the wrong scope before rewritting.

1939 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1940 delegate the secondary stack management when there is no suitable
1941 transient context, and the transient scope was intended to manage the

1943 transient scope creation logic by special casing assignment statements
1944 of controlled components for type initialization procedures.
1945 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
1946 the comment on usage.
1947 (Find_Transient_Context): Change the initinte loop into a while loop.
1948 Iterations schemes and iterator specifications are not valid transient
1949 contexts because they rely on special processing. Assignment statements
1950 are now treated as a normal transient context, special cases are
1951 handled by the caller. Add special processing for pragma Check.
1952 (Is_OK_Construct): Removed. Its functionality has been merged in
1953 routine Find_Transient_Context.
1954 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly

1957 the secondary stack.

2239 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2240
2241 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
2242 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
2243 (File_Type): Add Default_Initial_Condition aspect.
2244
2245 2018-01-11 Pascal Obry <obry@adacore.com>
2246
2247 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
2248
2249 2018-01-11 Bob Duff <duff@adacore.com>
2250
2251 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2252 to match what the Libadalang-based version does.
2253 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2254
2255 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2256
2257 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2258 if it contains at least one component declaration employing a function
2259 call returning on the secondary stack.
2260
2261 2018-01-11 Yannick Moy <moy@adacore.com>
2262
2263 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
2264 Update description of restriction SPARK_05 with SPARK 2014.
2265 * gnat_rm.texi: Regenerate.
2266
2267 2018-01-11 Vasiliy Fofanov <fofanov@adacore.com>
2268
2269 * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
2270
2271 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2272
2273 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
2274 sem_res.adb, sem_util.adb: Minor reformatting.
2275
2276 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2277
2278 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2279 has a delayed aspect which must be processed at the point the type is
2280 frozen. This mimics what is done when the predicate is provided by a
2281 source aspect.
2282
2283 2018-01-11 Doug Rupp <rupp@adacore.com>
2284
2285 * init.c (vxworks): Add macro checks for __aarch64__.
2286
2287 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2288
2289 * exp_util.adb (Add_Failure_Expression): New routine.
2290 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
2291 * sem_util.adb (Is_Current_Instance): Code cleanup.
2292
2293 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2294
2295 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2296 Default_Sec_Stack_Size.
2297 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2298 limit check so that the integer index does not overflow. Check the
2299 dynamic stack allocation does not cause the secondary stack pointer to
2300 overflow.
2301 (SS_Info): Align colons.
2302 (SS_Init): Cover the case when bootstraping with an old compiler that
2303 does not set Default_SS_Size.
2304
2305 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2306
2307 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2308 legality of an inherited operation that may require overriding, ignore
2309 primitive_wrappers that correspond to explicit operations that override
2310 an interface primitive.
2311 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2312 operation to which the class-wide expression applies is a protected op.
2313 with a primitive_wrapper, verify that the updated inherited expression
2314 does not contain an internal call to a protected function. This
2315 completes the implementation of AI12-0166.
2316
2317 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2318
2319 * ali.adb: Document the remaining letters available for ALI lines.
2320 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2321 * ali.ads: Update type With_Record. Field
2322 Implicit_With_From_Instantiation is no longer in use. Add field
2323 Implicit_With.
2324 * csinfo.adb (CSinfo): Remove the setup for attribute
2325 Implicit_With_From_Instantiation.
2326 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2327 either implicitly or explicitly withed.
2328 (Is_Implicit_With_Clause): New routine.
2329 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2330 confusion with the with clause attribute by the same name.
2331 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2332 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2333 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2334 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2335 for a parent unit.
2336 (Implicit_With_On_Parent): Mark the with clause as generated for a
2337 parent unit.
2338 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2339 instantiation are no longer marked as Implicit_With_From_Instantiation
2340 because they are already marked as implicit.
2341 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2342 which marks implicit with clauses as related to an instantiation.
2343 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2344 (Parent_With): New routine.
2345 (Set_Implicit_With_From_Instantiation): Removed.
2346 (Set_Parent_With): New routine.
2347 * sinfo.ads: Update the documentation of attribute Implicit_With.
2348 Remove attribute Implicit_With_From_Instantiation along with
2349 occurrences in nodes. Add attribute Parent_With along with occurrences
2350 in nodes.
2351 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
2352 (Parent_With): New routine along with pragma Inline.
2353 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
2354 (Set_Parent_With): New routine along with pragma Inline.
2355
2356 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2357
2358 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2359 entity when the enclosing construct is a body.
2360
2361 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2362
2363 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2364 Secondary_Stack_Size handling as a pragma is now generated for the
2365 corresponding aspect instead of an attribute. Pragma expression is
2366 relocated instead of evaluated. Discriminant of the corresponding
2367 record type is referenced rather than the type discriminant.
2368 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2369 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2370 * sem_ch13.adb (Analyze_One_Aspect): Transform
2371 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2372 because the attribute does not have visibility on a task type's
2373 discriminants when the type's definition is expanded.
2374 (Analyze_Attribute_Definition_Clause): Remove handling of
2375 Attribute_Secondary_Stack_Size.
2376 * snames.adb-tmpl, snames.ads-tmpl: Remove
2377 Attribute_Secondary_Stack_Size, no longer used.
2378
2379 2018-01-11 Justin Squirek <squirek@adacore.com>
2380
2381 * sem_ch8.adb: Minor comment fix.
2382
2383 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2384
2385 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2386 individual action because the action may denote a complex expression,
2387 such as a case statement, which in turn may contain additional
2388 transient objects.
2389
2390 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2391
2392 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2393 analysis on a copy of the expression with a copy of the index variable,
2394 because full expansion will rewrite construct into a loop with the
2395 original loop variable.
2396 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2397 expression is an iterated component association. Full analysis takes
2398 place when construct is rewritten as a loop.
2399 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2400 is not safe for in-place assignment.
2401 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2402 entity with no homonym and no other entity in the scope.
2403
2404 2018-01-11 Justin Squirek <squirek@adacore.com>
2405
2406 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2407 message to be printed on the pragma argument identifier.
2408
2409 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2410
2411 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2412 entity of the generated invariant procedure in order to construct a
2413 proper entity chain.
2414
2415 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2416
2417 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
2418 comment.
2419
2420 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2421
2422 * einfo.ads, einfo.adb (Activation_Record_Component,
2423 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2424 Allow E_Discriminant.
2425
2426 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2427
2428 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2429 for atomic access once the component size is taken into account and
2430 also do it if the component type is Atomic or Volatile_Full_Access.
2431
2432 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2433
2434 * gnatvsn.ads: Bump copyright year.

2437 Alan Hayward <alan.hayward@arm.com>
2438 David Sherwood <david.sherwood@arm.com>
2439
2440 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE
2441 as polynomial.
2442
2443 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2444 Alan Hayward <alan.hayward@arm.com>
2445 David Sherwood <david.sherwood@arm.com>
2446
2447 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION
2448 as polynomial.
2449
2450 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2451 Alan Hayward <alan.hayward@arm.com>
2452 David Sherwood <david.sherwood@arm.com>
2453
2454 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
2455 polynomial TYPE_VECTOR_SUBPARTS.
2456
2457 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2458 Alan Hayward <alan.hayward@arm.com>
2459 David Sherwood <david.sherwood@arm.com>

2464 2018-01-03 Jakub Jelinek <jakub@redhat.com>
2465
2466 Update copyright years.
2467
2468 * gnat_ugn.texi: Bump @copying's copyright year.
