3 * ali.ads: Fix casing in comment.
4 * ali-util.ads, ali-util.adb (Read_Withed_ALIs): Remove
5 Ignore_Errors parameter; it was only set to non-default value of
6 True when running in GNATprove_Mode and wrongly reset to False
7 when calling this routine recursively. Now in GNATprove mode we
8 want it to be always True, so in fact it is equivalent to
9 GNATProve_Mode flag itself (which was already used in this

45 tests for potential volatile or independent components. In
46 particular, do not call Prefix unless we know it's a slice.
48 2019-09-17 Dmitriy Anisimkov <anisimko@adacore.com>
50 * gsocket.h: Include sys/un.h.

66 from Look_For_Supported.
67 * libgnat/g-sothco.ads (Unix_Name_Length): New constant defining
68 maximum number of characters in local socket address path.
69 (Sockaddr): Add variant for Family_Unix address family. Move
70 Sin_Port and Sin_Family to Family_Inet section. Add Sin6_Port
71 and Sin6_Family to Family_Inet6 section.
72 (Set_Address): Add out parameter Length to return valuable
74 (Get_Address): Add input parameter Length to set valuable
76 * libgnat/g-sothco.adb: Support local unix address in socket
79 2019-09-17 Eric Botcazou <ebotcazou@adacore.com>
81 * exp_attr.adb (Expand_Size_Attribute): Chain the special cases
82 on the back-end path and rewrite the attribute appled to slices
83 of bit-packed arrays into the product of the Length and the
84 Compoent_Size attributes of the slices.
85 * exp_ch5.adb (Expand_Assign_Array_Bitfield): Use Size attribute
86 directly to compute the bitfield's size.
88 2019-09-17 Bob Duff <duff@adacore.com>
90 * exp_ch5.adb (Expand_Assign_Array_Loop_Or_Bitfield): Add tests
91 for potential volatile or independent components.
92 * libgnat/s-bituti.adb (Copy_Small_Bitfield,
93 Copy_Large_Bitfield): Move declarations to more appropriate

126 * gcc-interface/gigi.h (aggregate_type_contains_array_p): Declare.
127 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Record_Type>: For an
128 extension, test Has_Record_Rep_Clause instead of Has_Specified_Layout.
129 (adjust_packed): Return 0 if the type of the field is an aggregate
130 type that contains (or is) a self-referential array.
131 (type_has_variable_size): Delete.
132 * gcc-interface/utils.c (inish_record_type): Constify a variable.
133 (aggregate_type_contains_array_p): Add parameter SELF_REFERENTIAL.

135 <ARRAY_TYPE>: If it is true, return true only if the array type is
137 (create_field_decl): Streamline the setting of the alignment on the
138 field. Pass false to aggregate_type_contains_array_p.
140 2019-08-30 Eric Botcazou <ebotcazou@adacore.com>
142 * gcc-interface/trans.c (lvalue_required_p) <N_Slice>: Adjust GNU_TYPE
143 in the recursive call.

148 * gcc-interface/utils.c (build_template): Deal with parameters
149 passed by pointer to component of multi-dimensional arrays.

164 Remove redundant test and adjust comments. Minor tweaks.
165 * gcc-interface/trans.c (Call_to_gnu): Do not generate range checks,
166 instead assert that the Do_Range_Check flag is not set. Adjust call
167 to convert_with_check.
168 (gnat_to_gnu): Likewise.
169 (assoc_to_constructor): Likewise.
170 (pos_to_constructor): Likewise. Remove GNAT_COMPONENT_TYPE parameter.
171 (emit_range_check): Delete.
172 (convert_with_check): Remove RANGE_P parameter and adjust. Do a single
173 overflow check for modular types.
175 2019-08-23 Jakub Jelinek <jakub@redhat.com>
178 * gcc-interface/misc.c (gnat_post_options): Set flag_excess_precision
179 instead of flag_excess_precision_cmdline.

188 * einfo.adb (Is_Discriminal): Remove extra parens.
189 (Is_Constant_Object): Simplify by reusing Ekind_In.
190 (Is_Prival): Remove extra parens.
191 * checks.adb, exp_ch4.adb, sem_ch3.adb, sem_spark.adb: Minor

198 (Iter_First, Iter_Next): Primitives used for iteration.
200 2019-08-21 Yannick Moy <moy@adacore.com>
202 * sem_ch3.adb (Analyze_Subtype_Declaration): Inherit RM_Size
203 field for formal type parameters in generic instantiations.
205 2019-08-21 Yannick Moy <moy@adacore.com>
207 * sem_spark.adb: Update references to the SPARK RM.
209 2019-08-21 Eric Botcazou <ebotcazou@adacore.com>
211 * repinfo.adb (List_Array_Info): In -gnatR4 mode, set the
212 relevant flag on the component type here instead of...
213 (List_Object_Info): Likewise for the object type.
214 (List_Entities): ...here. In -gnatR4 mode, recurse into
215 entities local to a record type.
216 (List_Component_Layout): In -gnatR4 mode, mark the type as
219 2019-08-21 Bob Duff <duff@adacore.com>
221 * Makefile.rtl (GNATRTL_NONTASKING_OBJS): Add s-bitutil.o and
223 * exp_ch5.adb (Expand_Assign_Array_Bitfield): New function to
224 generate a call to Copy_Bitfield. This is disabled for now.
225 (Expand_Assign_Array_Loop_Or_Bitfield): New function to decide
226 whether to call Expand_Assign_Array_Bitfield.
227 (Expand_Assign_Array): Call Expand_Assign_Array_Loop_Or_Bitfield
228 instead of Expand_Assign_Array_Loop.
229 * libgnat/s-bitfie.ads, libgnat/s-bituti.adb,
230 libgnat/s-bituti.ads: New units.
231 * rtsfind.ads: Add enum literals for accessing Copy_Bitfield.
233 2019-08-21 Piotr Trojanek <trojanek@adacore.com>
235 * bindo-graphs.ads (Iterate_Edges_To_Successors): Fix typo in
237 * bindo-graphs.adb (Delete_Edge): Fix layout in parameter list.
239 2019-08-21 Gary Dismukes <dismukes@adacore.com>
241 * exp_ch3.adb (Build_Master): Suppress call to
242 Build_Class_Wide_Master in the case where the
243 access-to-limited-class-wide type was created for a component in
244 an entry's formal parameter
245 block (Is_Parameter_Block_Component_Type), to prevent a master
246 from being created for such access types generated by the front
247 end in a task spec for entry formals in a parameter block. Add
248 a ??? about whether this suppression should be done more
249 generally (such as by using Comes_From_Source).
251 2019-08-21 Eric Botcazou <ebotcazou@adacore.com>
253 * exp_ch6.adb (Expand_N_Extended_Return_Statement): In the case
254 of a built-in-place function that doesn't need a BIP_Alloc_Form
255 parameter but returns unconstrained, build the return
256 consistently using the function's result subtype. Remove bypass
257 added in previous change.
259 2019-08-21 Piotr Trojanek <trojanek@adacore.com>
261 * sem_prag.adb (Max_Entry_Queue_Length): Do not substitute
262 expression of the pragma argument with its value during
264 * sem_util.adb (Get_Max_Queue_Length): Compute value of the
265 pragma argument when needed.
267 2019-08-21 Yannick Moy <moy@adacore.com>
269 * checks.adb (Install_Null_Excluding_Check): Do not install
270 check in GNATprove mode.
272 2019-08-21 Yannick Moy <moy@adacore.com>
274 * sem_spark.adb (Process_Path): Do nothing on address of
277 2019-08-21 Eric Botcazou <ebotcazou@adacore.com>
279 * exp_util.adb (Finalize_Address): Deal consistently with
280 subtypes of private protected types.
282 2019-08-21 Piotr Trojanek <trojanek@adacore.com>
284 * exp_util.adb (Corresponding_Runtime_Package): Use high-level

289 2019-08-21 Javier Miranda <miranda@adacore.com>
291 * sem_util.adb (Update_Named_Associations): Update
292 First_Named_Actual when the subprogram call has a single named
295 2019-08-21 Joel Brobecker <brobecker@adacore.com>
297 * doc/Makefile (mk_empty_dirs): New (PHONY) rule.
298 (%.html, %.pdf, %.txt, %.info, %.texinfo): Add dependencies on
301 2019-08-21 Justin Squirek <squirek@adacore.com>
303 * doc/gnat_rm/implementation_defined_pragmas.rst: Modify
304 documentation to reflect expected behavior.
305 * gnat_rm.texi: Regenerate.
306 * sem_prag.adb (Analyze_Pragma): Modify handling of pragma
307 Max_Entry_Queue_Length to not reject integer values of negative
309 * sem_util.adb (Get_Max_Queue_Length): Add processing for values
310 of negative one to fit within the current scheme.
312 2019-08-20 Arnaud Charlet <charlet@adacore.com>
314 * exp_unst.adb (Unnest_Subprograms, Unnest_Subprogram): Take
315 inlining (-gnatn) into account.
317 2019-08-20 Ed Schonberg <schonberg@adacore.com>
319 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case
320 Storage_Size): If the expression for Storage_Size is not static
321 it may depend on characterstics of another type that may bot be
322 frozen yet, so the elaboration of the expression for the aspect
323 must be attached directly to the freeze actions of the type to
326 2019-08-20 Piotr Trojanek <trojanek@adacore.com>
328 * exp_util.adb (Build_DIC_Procedure_Declaration): Set the last
329 entity of the generated Default_Initial_Condition procedure in
330 order to construct a proper entity chain.
332 2019-08-20 Yannick Moy <moy@adacore.com>
334 * exp_spark.adb (Expand_SPARK_N_Slice_Or_Indexed_Component):
335 Renaming of function to apply to slices as well.
336 (Expand_SPARK): Expand prefix of slices of access type.
338 2019-08-20 Bob Duff <duff@adacore.com>
340 * exp_aggr.adb (Expand_Array_Aggregate): Use build-in-place in
341 the nonlimited case in STEP 4. This improves the efficiency of
342 things like (1 .. 1000 => <>). We still generate some code for
343 that, unfortunately, but it is much improved.
344 (Aggr_Assignment_OK_For_Backend): Return false if <> components
347 2019-08-20 Bob Duff <duff@adacore.com>
349 * exp_ch6.adb (Needs_BIP_Alloc_Form): Call
350 Requires_Transient_Scope rather than checking constrainedness
351 and so forth. We have previously improved
352 Requires_Transient_Scope to return False in various cases,
353 notably a limited record with an access discriminant. This
354 change takes advantage of that to avoid using the secondary
355 stack for functions returning such types.
356 (Make_Build_In_Place_Call_In_Allocator): Be consistent by
357 calling Needs_BIP_Alloc_Form rather than Is_Constrained and so
359 * sem_ch4.adb (Analyze_Allocator): The above change causes the
360 compiler to generate code that is not legal Ada, in particular
361 an uninitialized allocator for indefinite subtype. This is
362 harmless, so we suppress the error message in this case.

385 flags Is_Constr_Subt_For_U_Nominal and _UN_Aliased to full view
388 2019-08-20 Ed Schonberg <schonberg@adacore.com>
390 * exp_attr.adb (Expand_Loop_Entry_Attribute): When expanding a
391 loop entry attribute for a while_loop we construct a function
392 that incorporates the expanded condition of the loop. The itypes
393 that may be generated in that expansion must carry the scope of
394 the constructed function for proper handling in gigi.
396 2019-08-20 Ed Schonberg <schonberg@adacore.com>
398 * exp_disp.adb (Build_Class_Wide_Check, Replace_Formals): When a
399 dispatching call tp a subprogram with a class-wide precondition
400 occurrs in the same declarative part as the ancestor subprogram
401 being called, the`expression for the precondition has not been
402 analyzed yet. Such a call may appear, e.g. in an expression
403 function. In that case, the replacement of formals by actuals in
404 the call cannot use the formal entities of the subprogram being
405 called, and the occurrence of the formals in the expression must
406 be located by name (Chars fields) as would be done at a later
407 freeze point, when the expression is resolved in the context of
408 the subprogram itself.
410 2019-08-20 Bob Duff <duff@adacore.com>
412 * sem_prag.adb (Persistent_BSS): If an initialization is present
413 because of Initialize_Scalars or Normalize_Scalars, generate an
414 implicit pragma Suppress_Initialization to remove that, because
415 initialization is not allowed for these variables. Other
416 initializations remain illegal.
418 2019-08-20 Gary Dismukes <dismukes@adacore.com>
420 * sem_ch3.adb (OK_For_Limited_Init_In_05): In the case of type
421 conversions, apply the recursive call to the Original_Node of
422 the expression Exp rather than the Expression of the
423 Original_Node, in the case where Exp has been rewritten;
424 otherwise, when Original_Node is the same as Exp, apply the
425 recursive call to the Expression.
426 (Check_Initialization): Revise condition for special check on
427 type conversions of limited function calls to test Original_Node
428 (avoiding spurious errors on expanded unchecked conversions
429 applied to build-in-place dispatching calls).
431 2019-08-20 Patrick Bernardi <bernardi@adacore.com>
433 * exp_aggr.adb (Expand_Record_Aggregate): Always convert a
434 record Aggregate to assignment statements if the option
435 Aggregate_Individually_Assign is set.
436 * opt.ads (Aggregate_Individually_Assign): New option.
437 * par-prag.adb (Prag): Add Pragma_Aggregate_Individually_Assign.
438 * sem_prag.adb (Analyze_Pragma): Likewise.
439 * snames.ads-tmpl: Add Pragma_Aggregate_Individually_Assign and
440 Name_Aggregate_Individually_Assign.

449 versions prior to Ada 2020.
451 2019-08-20 Bob Duff <duff@adacore.com>
453 * freeze.adb (Is_Atomic_VFA_Aggregate): Make the temp for
454 initialization of the atomic variable be constant. This is
455 cleaner, and might improve efficiency.
457 2019-08-20 Eric Botcazou <ebotcazou@adacore.com>

460 relevant flag on the implicit base type of a record subtype.
462 2019-08-20 Bob Duff <duff@adacore.com>
464 * sem_eval.adb (Expr_Value): Implement the case of an unchecked
465 conversion of a static expression.
467 2019-08-20 Bob Duff <duff@adacore.com>
469 * sem_ch13.adb (Is_Null_Array): New function, used to detect the
470 null array case; used to warn about uncheckedly converting to a
471 zero-sized array. It is unfortunate that we can't just check
472 the size, and warn on all cases of converting from a
473 nonzero-sized type to a zero-sized one. That's because "0" means
474 two different things: "size is zero" and "size is unknown".
475 Until we fix that design flaw, we need this more targeted fix.
477 2019-08-20 Bob Duff <duff@adacore.com>
479 * libgnat/a-cborma.adb, libgnat/a-cborse.adb (Clear): Repeatedly
480 call Delete. This avoids clearing the free list, which
481 substantially speeds up future Delete operations.
483 2019-08-20 Bob Duff <duff@adacore.com>
485 * sem_ch13.adb (Component_Order_Check): New procedure to check

492 2019-08-20 Bob Duff <duff@adacore.com>
494 * sem_ch13.adb (Object_Size): Give an error for zero. It really
495 rubs me the wrong way that we don't honor "for T'Object_Size use
496 0;", but it's not important enough to fix. In any case, if we're
497 not going to obey the clause, we should give an error.

501 * errout.adb (Error_Msg_Internal): Set Warn_Err in case of

505 messages. Clean up code, simplify, remove unnecessary block
506 statement, add renaming of table entry.
507 * erroutc.ads (Warning_Treated_As_Error): Fix comment: no such
508 thing as Set_Warning_As_Error.
509 * opt.ads: Clean up comments and move related declarations near
511 * par-prag.adb: Process Warning_As_Error. This is necessary
512 because many style warning happen during parsing.
513 * sem_prag.adb: Use new Acquire_Warning_Match_String.
514 * sem_util.ads, sem_util.adb (Acquire_Warning_Match_String): New
515 function shared by par-prag.adb and sem_prag.adb. Replaces the
516 procedure in sem_prag.adb. Avoid use of global variables.
517 * stringt.ads, stringt.adb (To_String): New function to convert

529 (Unit_Name_Hash): New function declaration.
530 (Unit_Names): New simple hash table.
531 (Init_Unit_Name): New procedure declaration.
532 * lib.adb (Set_Unit_Name): Unregister the old name in the table,
533 if any, and then register the new name.
534 (Init_Unit_Name): New procedure.
535 (Is_Loaded): Reimplement using a lookup in the names table.
536 (Remove_Unit): Unregister the name.
537 (Unit_Name_Hash): New function.
538 * lib-load.adb (Create_Dummy_Package_Unit): Call Init_Unit_Name.
539 (Load_Unit): Use a lookup in the names table to find out whether
540 the unit has already been loaded. Call Init_Unit_Name and then

543 (Make_Instance_Unit): Likewise.
544 * lib-writ.adb (Ensure_System_Dependency): Likewise.

615 2019-08-19 Bob Duff <duff@adacore.com>
617 * exp_attr.adb (Attribute_Valid): Correct the handling of
618 private types where the full type is modular. System.Address is
619 an example. Otherwise, we convert uncheckedly to a signed type,
620 so we get an incorrect range 0 .. -1, for which all values will
621 fail. The 'Valid attribute is illegal for such types, but we
622 generate such illegal attribute_references for 'Valid_Scalars,
623 and we generate 'Valid_Scalars when the -gnateV switch is used.
624 Rename Btyp --> PBtyp to avoid hiding the outer Btyp, which was
626 * libgnat/a-except.adb: Set the Exception_Raised component.
627 Otherwise, we have incorrect reads of invalid data.

662 * sem_ch6.adb (Check_Synchronized_Overriding): Complete
663 predicate that applies legality check in 9.4 (11.9/2): if an
664 inherited subprogram is implemented by a protected procedure or
665 entry, its first paarameter must be out, in_out or
668 2019-08-19 Javier Miranda <miranda@adacore.com>
671 * exp_atag.ads, exp_atag.adb (Build_Inherit_Predefined_Prims):
672 Adding formal to specify how many predefined primitives are
673 inherited from the parent type.
674 * exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
675 (Make_Secondary_DT): Compute the number of predefined primitives
676 of all tagged types (including tagged types not defined at
677 library level). Previously we unconditionally relied on the
678 Max_Predef_Prims constant value when building the dispatch
679 tables of tagged types not defined at library level (thus
680 consuming more memory for their dispatch tables than required).
681 (Make_DT): Compute the number of predefined primitives that must
682 be inherited from their parent type when building the dispatch
683 tables of tagged types not defined at library level. Previously
684 we unconditionally relied on the Max_Predef_Prims constant value
685 when building the dispatch tables of tagged types not defined at
686 library level (thus copying more data than required from the
689 2019-08-19 Bob Duff <duff@adacore.com>
691 * sem_ch13.adb (Record_Hole_Check): Procedure to check for holes
692 that incudes processing type extensions. A type extension is
693 processed by first calling Record_Hole_Check recursively on the
694 parent type to compute the bit number after the last component
697 2019-08-19 Gary Dismukes <dismukes@adacore.com>
699 * checks.adb (Length_Mismatch_Info_Message): New function in
700 Selected_Length_Checks to return a message indicating the
701 element counts for the mismatched lengths for a failed
702 compile-time length check.
703 (Plural_Or_Singular_Ending): Support function in
704 Length_Mismatch_Info_Message to return either "" or "s", for
705 concatenating to the end of words.
706 (Selected_Length_Checks): Pass the result of
707 Length_Mismatch_Info_Message as an extra warning message to
708 Compile_Time_Constraint_Error to indicate the mismatched lengths
709 for a failed compile-time length check.
710 * sem_util.ads (Compile_Time_Constraint_Error): Add an optional
711 message formal (Extra_Msg), defaulted to the empty string.
712 * sem_util.adb (Compile_Time_Constraint_Error): Output an extra
713 message following the main warning message (when Extra_Msg is
714 not the empty string).
716 2019-08-19 Patrick Bernardi <bernardi@adacore.com>
718 * socket.c: Removed the redefinition of getaddrinfo, getnameinfo
719 and freeaddrinfo to internal VxWorks kernel calls because they
720 are, well, internal kernel calls and cannot be called from RTPs.
721 VxWorks provides the necessary components to call these routines
724 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
726 * exp_dist.adb (Is_Generic_Actual_Subtype): New predicate.
727 (Build_From_Any_Call, Build_To_Any_Call, Build_TypeCode_Call):
728 Use it instead of Is_Generic_Actual_Type flag to detect subtypes
729 representing generic actual types.
731 2019-08-19 Ed Schonberg <schonberg@adacore.com>
733 * sem_warn.adb (Check_References, Generic_Body_Formal): When a
734 formal parameter of a generic subprogram is not referenced in
735 the body, place the corresponding warning on the corresponding
736 entity in the specification of the generic body, as is done for
737 non-generic subprograms.
739 2019-08-19 Bob Duff <duff@adacore.com>
741 * errout.ads (Size_Too_Small_Message): New constant.

764 parameter of the generic. Function used to decide whether a
765 function is a pledge function.
766 (Check_Not_Borrowed): Disable check inside the second parameter
767 of a pledge function for the path borrowed by the first
768 parameter. Also disable checks for entities inside a Global

786 * sem_ch3.adb (Derived_Enumeration_Type): Do no freeze anonymous
787 base type if the bounds in the derived type declaration are
788 literals of the type.

801 a pending instantiation for the body of the package.
803 2019-08-19 Olivier Hainque <hainque@adacore.com>
805 * gcc-interface/trans.c (Acc_Loop_to_gnu): Return the openacc
806 BIND_EXPR node we have constructed on purpose. Remove unused
809 2019-08-19 Pierre-Marie de Rodat <derodat@adacore.com>
811 * gcc-interface/lang.opt (fdump-scos): Define.
812 * gcc-interface/misc.c (gnat_handle_option): Handle
815 2019-08-14 Joffrey Huguet <huguet@adacore.com>
817 * libgnat/a-cofuba.ads: Add a Length attribute to type
818 Container. Add a type Array_Base which replaces the previous
819 Elements attribute of Container.
820 (Content_Init): New subprogram. It is used to initialize the
821 Base attribute of Container.
822 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
823 resize the underlying array of a container if necessary.
824 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,
825 Union): Update to match changes in type declarations.
826 (Add): Modify body to damp the time and space cost in a specific
828 (Content_Init): New subprogram. It is used to initialize the
829 Base attribute of Container.
830 (Remove): Modify body to damp the time and space cost in a

836 and do not give an error.

843 * inline.adb (Add_Pending_Instantiation): Fix off-by-one error
844 in the comparison against the maximum number of instantiations.
846 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
848 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
849 in the comparison against the maximum number of instantiations.
851 2019-08-14 Ed Schonberg <schonberg@adacore.com>
853 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
854 involves a Ghost aspect it may have been replaced by a null
855 statement; use the original node to find next Rep_Item.
856 * repinfo.adb (List_Entities): Do not list an Ignored
857 Ghost_Entity, for which information may have been deleted.
859 2019-08-14 Bob Duff <duff@adacore.com>
861 * sem_prag.ads, sem_prag.adb
862 (Process_Compile_Time_Warning_Or_Error): In parameterless
863 version, improve detection of whether we are in a generic unit
864 to cover the case of an instance within a generic unit.
865 (Process_Compile_Time_Warning_Or_Error): Rename the
866 two-parameter version to be
867 Validate_Compile_Time_Warning_Or_Error, and do not export it.
868 Issue a warning if the condition is not known at compile time.
869 The key point is that the warning must be given only for pragmas
870 deferred to the back end, because the back end discovers
871 additional values that are known at compile time. Previous
872 changes in this ticket have enabled this by deferring to the
873 back end without checking for special cases such as 'Size.
874 (Validate_Compile_Time_Warning_Or_Error): Rename to be
875 Defer_Compile_Time_Warning_Error_To_BE.
876 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):
877 Add new switches -gnatw_c and -gnatw_C to control the above
879 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
880 Document new switches.
881 * gnat_ugn.texi: Regenerate.
883 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
885 * sem_ch12.adb (Might_Inline_Subp): Rework comment and restrict
886 the shortcut based on Is_Inlined to the back-end inlining case.
888 2019-08-14 Bob Duff <duff@adacore.com>
890 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
891 protected functions to get rid of spurious error. The
892 transformation done by this procedure triggers legality errors
893 in the generated code in this case.
895 2019-08-14 Bob Duff <duff@adacore.com>
897 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
898 processing to the back end in all cases where the pragma's
899 condition is not known at compile time during the front end
900 (except in generics), as opposed to detecting 'Size attributes
901 and the like. This ensures that we take advantage of whatever
902 can be compile-time known after running the back end, as opposed
903 to having the front end guess what the back end can do. Remove
904 a little duplicated code at the call site.
905 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
906 Elists while in Validate_Compile_Time_Warning_Errors, because it
907 does analysis and name resolution, which sometimes involves
910 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
912 * einfo.ads (Is_Called): Document new usage on E_Package
914 * einfo.adb (Is_Called): Accept E_Package entities.
915 (Set_Is_Called): Likewise.
916 * exp_ch6.adb (Expand_Call_Helper): Move code dealing with
917 instances for back-end inlining to Add_Inlined_Body.
918 * inline.ads: Remove with clauses for Alloc and Table.
919 (Pending_Instantiations): Move to...
920 * inline.adb: Add with clauses for Alloc, Uintp, Table and
922 (Backend_Instances): New variable.
923 (Pending_Instantiations): ...here.
924 (Called_Pending_Instantiations): New table.
925 (Node_Table_Size): New constant.
926 (Node_Header_Num): New subtype.
927 (Node_Hash): New function.
928 (To_Pending_Instantiations): New hash table.
929 (Add_Inlined_Body): Bail out early for subprograms in the main
930 unit or subunit. Likewise if the Is_Called flag is set. If the
931 subprogram is an instance, invoke Add_Inlined_Instance. Call
932 Set_Is_Called earlier. If the subrogram is within an instance,
933 invoke Add_Inlined_Instance. Also deal with the case where the
934 call itself is within an instance.
935 (Add_Inlined_Instance): New procedure.
936 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
937 (Add_Pending_Instantiation): Move the defence against ludicruous
938 number of instantiations to here. When back-end inlining is
939 enabled, associate an instantiation with its index in table and
940 mark a few selected kinds of instantiations as always needed.
941 (Initialize): Set Backend_Instances to No_Elist.
942 (Instantiate_Body): New procedure doing the work extracted
944 (Instantiate_Bodies): ...here. When back-end inlining is
945 enabled, loop over Called_Pending_Instantiations instead of
946 Pending_Instantiations.
947 (Is_Nested): Minor tweak.
948 (List_Inlining_Info): Also list the contents of
950 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
951 is set and otherwise set it before returning true.
952 (Analyze_Package_Instantiation): Remove the defence against
953 ludicruous number of instantiations. Invoke
954 Remove_Dead_Instance instead of doing the removal manually if
955 there is a guaranteed ABE.
957 2019-08-14 Gary Dismukes <dismukes@adacore.com>
959 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
960 of an interface type, create an expression function (that
961 returns False) rather than declaring an abstract function.
962 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
963 False unconditionally at the start of the loop creating wrappers
964 for inherited operations.
966 2019-08-14 Bob Duff <duff@adacore.com>
968 * table.adb: Assert that the table is not locked when increasing
969 Last, even if it doesn't cause reallocation. In other words,
970 assert that on operations that MIGHT cause reallocation.
971 * table.ads: Fix comment accordingly.
973 2019-08-14 Arnaud Charlet <charlet@adacore.com>
975 * doc/gnat_ugn/gnat_and_program_execution.rst: Remove
976 documentation of gnatelim.
978 2019-08-14 Bob Duff <duff@adacore.com>
980 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
981 warning to the Sloc of the first pragma argument, rather than to
982 the pragma itself. This is to make pragmas processed after the
983 back end use the same Sloc as pragmas processed earlier, in the
984 front end. There's no reason for this discrepancy, and it
985 hinders further work on this ticket.
987 2019-08-14 Bob Duff <duff@adacore.com>
989 * sem.ads (Inside_A_Generic): Remove the ??? comment.
991 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
993 * inline.ads (Pending_Descriptor): Delete.
994 * inline.adb (Initialize): Do not initialize it.

997 Set_Delay_Subprogram_Descriptors instead of Delay_Descriptors
1000 2019-08-14 Bob Duff <duff@adacore.com>
1002 * exp_aggr.adb (Init_Hidden_Discriminants): Avoid processing the
1003 wrong discriminant, which could be of the wrong type.
1005 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
1007 * sem_ch12.adb (Analyze_Instance_And_Renamings): Do not reset
1008 the Is_Generic_Instance flag previously set on the package
1009 generated for the instantiation of a generic subprogram.
1011 2019-08-14 Ed Schonberg <schonberg@adacore.com>

1021 2019-08-14 Yannick Moy <moy@adacore.com>
1023 * sem_spark.adb, sem_spark.ads (Is_Legal): New function exposed
1024 for use in GNATprove, to test legality rules not related to
1026 (Check_Declaration_Legality): Extract the part of
1027 Check_Declaration that checks rules not related to permissions.
1028 (Check_Declaration): Call the new Check_Declaration_Legality.
1029 (Check_Type_Legality): Rename of Check_Type. Introduce
1030 parameters to force or not checking, and update a flag detecting
1032 (Check_Node): Ignore attribute references in statement position.
1034 2019-08-14 Yannick Moy <moy@adacore.com>
1036 * sem_spark.adb (Check_Old_Loop_Entry): New procedure to check
1037 correct use of Old and Loop_Entry.
1038 (Check_Node): Check subprogram contracts.
1039 (Check_Pragma): Check Loop_Variant.
1040 (Check_Safe_Pointers): Apply checking to library-level
1041 subprogram declarations as well, in order to check their

1051 * sem_ch7.adb (Install_Private_Declarations)
1052 <Swap_Private_Dependents>: Do not rely solely on the
1053 Is_Child_Unit flag on the unit to recurse.
1054 (Uninstall_Declarations) <Swap_Private_Dependents>: New
1055 function. Use it to recurse on the private dependent entities
1058 2019-08-14 Javier Miranda <miranda@adacore.com>
1060 * exp_aggr.adb (Is_CCG_Supported_Aggregate): Return False for
1061 arrays with bounds not known at compile time.
1063 2019-08-14 Ed Schonberg <schonberg@adacore.com>
1065 * sem_util.adb (New_Copy_Tree, Visit_Entity): A quantified
1066 expression includes the implicit declaration of the loop
1067 parameter. When a quantified expression is copied during
1068 expansion, for example when building the precondition code from

1609 Freeze_Entity_Checks): Include Aspect_CPU with other aspects
1610 whose expresssion may depend on a discriminant, and thus require
1611 that components of the type be made visible.
1613 2019-07-23 Eric Botcazou <ebotcazou@adacore.com>
1615 * checks.adb (Convert_And_Check_Range): Add Suppress parameter

1684 'Valid as a replacement for a range check on a discrete type
1685 when the bounds of the range are given by type conversions,
1686 because in such a case there are distinct types involved and the
1687 subbested attribute replacement would be misplaced.
1689 2019-07-22 Yannick Moy <moy@adacore.com>
1691 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,
1692 Is_Subpath_Expression): Add parameter Is_Traversal to adapt

1753 libgnat/s-valwch.ads: Change categorization of packages that
1754 implement attribute 'Value from Pure to Preelaborate, to prevent
1755 undesirable optimizations when the evaluation of the attribute
1756 raises Constraint_Error, but subsequent use of the result of
1757 this evsaluation is removed by a subsequent optimization.

1774 Image_Enumeration_16, Image_Enumeration_32): Define the index of
1775 Index_Table with range Natural'First .. Names'Length since in
1776 the worst case all the literals of the enumeration type would be
1777 single letter literals and the Table built by the frontend would
1778 have as many components as the length of the names string. As a
1779 result of this enhancement, the internal tables declared using
1780 Index_Table have a length closer to the real needs, thus
1781 avoiding the declaration of large arrays on 32-bit CCG targets.

1947 moved to GNATprove backend.
1948 * sem_spark.ads, sem_spark.adb (Sem_SPARK): Is now a generic
1949 unit. Takes as parameters:
