3 * doc/gnat_rm/implementation_defined_pragmas.rst: Modify
4 documentation to reflect expected behavior.
5 * gnat_rm.texi: Regenerate.
6 * sem_prag.adb (Analyze_Pragma): Modify handling of pragma
7 Max_Entry_Queue_Length to not reject integer values of negative
9 * sem_util.adb (Get_Max_Queue_Length): Add processing for values
10 of negative one to fit within the current scheme.
12 2019-08-20 Arnaud Charlet <charlet@adacore.com>
14 * exp_unst.adb (Unnest_Subprograms, Unnest_Subprogram): Take
15 inlining (-gnatn) into account.
17 2019-08-20 Ed Schonberg <schonberg@adacore.com>
19 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case
20 Storage_Size): If the expression for Storage_Size is not static
21 it may depend on characterstics of another type that may bot be
22 frozen yet, so the elaboration of the expression for the aspect
23 must be attached directly to the freeze actions of the type to
26 2019-08-20 Piotr Trojanek <trojanek@adacore.com>
28 * exp_util.adb (Build_DIC_Procedure_Declaration): Set the last
29 entity of the generated Default_Initial_Condition procedure in
30 order to construct a proper entity chain.
32 2019-08-20 Yannick Moy <moy@adacore.com>
34 * exp_spark.adb (Expand_SPARK_N_Slice_Or_Indexed_Component):
35 Renaming of function to apply to slices as well.
36 (Expand_SPARK): Expand prefix of slices of access type.
38 2019-08-20 Bob Duff <duff@adacore.com>
40 * exp_aggr.adb (Expand_Array_Aggregate): Use build-in-place in
41 the nonlimited case in STEP 4. This improves the efficiency of
42 things like (1 .. 1000 => <>). We still generate some code for
43 that, unfortunately, but it is much improved.
44 (Aggr_Assignment_OK_For_Backend): Return false if <> components
47 2019-08-20 Bob Duff <duff@adacore.com>
49 * exp_ch6.adb (Needs_BIP_Alloc_Form): Call
50 Requires_Transient_Scope rather than checking constrainedness
51 and so forth. We have previously improved
52 Requires_Transient_Scope to return False in various cases,
53 notably a limited record with an access discriminant. This
54 change takes advantage of that to avoid using the secondary
55 stack for functions returning such types.
56 (Make_Build_In_Place_Call_In_Allocator): Be consistent by
57 calling Needs_BIP_Alloc_Form rather than Is_Constrained and so
59 * sem_ch4.adb (Analyze_Allocator): The above change causes the
60 compiler to generate code that is not legal Ada, in particular
61 an uninitialized allocator for indefinite subtype. This is
62 harmless, so we suppress the error message in this case.

83 * sem_ch3.adb (Analyze_Object_Declaration): If actual type is
84 private and distinct from nominal type in declaration, propagate
85 flags Is_Constr_Subt_For_U_Nominal and _UN_Aliased to full view
88 2019-08-20 Ed Schonberg <schonberg@adacore.com>
90 * exp_attr.adb (Expand_Loop_Entry_Attribute): When expanding a
91 loop entry attribute for a while_loop we construct a function
92 that incorporates the expanded condition of the loop. The itypes
93 that may be generated in that expansion must carry the scope of
94 the constructed function for proper handling in gigi.
96 2019-08-20 Ed Schonberg <schonberg@adacore.com>
98 * exp_disp.adb (Build_Class_Wide_Check, Replace_Formals): When a
99 dispatching call tp a subprogram with a class-wide precondition
100 occurrs in the same declarative part as the ancestor subprogram
101 being called, the`expression for the precondition has not been
102 analyzed yet. Such a call may appear, e.g. in an expression
103 function. In that case, the replacement of formals by actuals in
104 the call cannot use the formal entities of the subprogram being
105 called, and the occurrence of the formals in the expression must
106 be located by name (Chars fields) as would be done at a later
107 freeze point, when the expression is resolved in the context of
108 the subprogram itself.
110 2019-08-20 Bob Duff <duff@adacore.com>
112 * sem_prag.adb (Persistent_BSS): If an initialization is present
113 because of Initialize_Scalars or Normalize_Scalars, generate an
114 implicit pragma Suppress_Initialization to remove that, because
115 initialization is not allowed for these variables. Other
116 initializations remain illegal.
118 2019-08-20 Gary Dismukes <dismukes@adacore.com>
120 * sem_ch3.adb (OK_For_Limited_Init_In_05): In the case of type
121 conversions, apply the recursive call to the Original_Node of
122 the expression Exp rather than the Expression of the
123 Original_Node, in the case where Exp has been rewritten;
124 otherwise, when Original_Node is the same as Exp, apply the
125 recursive call to the Expression.
126 (Check_Initialization): Revise condition for special check on
127 type conversions of limited function calls to test Original_Node
128 (avoiding spurious errors on expanded unchecked conversions
129 applied to build-in-place dispatching calls).
131 2019-08-20 Patrick Bernardi <bernardi@adacore.com>
133 * exp_aggr.adb (Expand_Record_Aggregate): Always convert a
134 record Aggregate to assignment statements if the option
135 Aggregate_Individually_Assign is set.
136 * opt.ads (Aggregate_Individually_Assign): New option.
137 * par-prag.adb (Prag): Add Pragma_Aggregate_Individually_Assign.
138 * sem_prag.adb (Analyze_Pragma): Likewise.
139 * snames.ads-tmpl: Add Pragma_Aggregate_Individually_Assign and
140 Name_Aggregate_Individually_Assign.
141 * doc/gnat_rm/implementation_defined_pragmas.rst: Document
142 pragma Aggregate_Individually_Assign.
143 * gnat_rm.texi: Regenerate.
145 2019-08-20 Bob Duff <duff@adacore.com>
147 * par-ch4.adb: Minor wording change in error messages.
148 * sem_aggr.adb (Resolve_Delta_Aggregate): Emit an error for Ada
149 versions prior to Ada 2020.
151 2019-08-20 Bob Duff <duff@adacore.com>
153 * freeze.adb (Is_Atomic_VFA_Aggregate): Make the temp for
154 initialization of the atomic variable be constant. This is
155 cleaner, and might improve efficiency.
157 2019-08-20 Eric Botcazou <ebotcazou@adacore.com>
159 * repinfo.adb (List_Record_Info): In -gnatR4 mode, set the
160 relevant flag on the implicit base type of a record subtype.
162 2019-08-20 Bob Duff <duff@adacore.com>
164 * sem_eval.adb (Expr_Value): Implement the case of an unchecked
165 conversion of a static expression.
167 2019-08-20 Bob Duff <duff@adacore.com>
169 * sem_ch13.adb (Is_Null_Array): New function, used to detect the
170 null array case; used to warn about uncheckedly converting to a
171 zero-sized array. It is unfortunate that we can't just check
172 the size, and warn on all cases of converting from a
173 nonzero-sized type to a zero-sized one. That's because "0" means
174 two different things: "size is zero" and "size is unknown".
175 Until we fix that design flaw, we need this more targeted fix.
177 2019-08-20 Bob Duff <duff@adacore.com>
179 * libgnat/a-cborma.adb, libgnat/a-cborse.adb (Clear): Repeatedly
180 call Delete. This avoids clearing the free list, which
181 substantially speeds up future Delete operations.
183 2019-08-20 Bob Duff <duff@adacore.com>
185 * sem_ch13.adb (Component_Order_Check): New procedure to check
186 for out-of-order clauses.

192 2019-08-20 Bob Duff <duff@adacore.com>
194 * sem_ch13.adb (Object_Size): Give an error for zero. It really
195 rubs me the wrong way that we don't honor "for T'Object_Size use
196 0;", but it's not important enough to fix. In any case, if we're
197 not going to obey the clause, we should give an error.
199 2019-08-20 Bob Duff <duff@adacore.com>
201 * errout.adb (Error_Msg_Internal): Set Warn_Err in case of
203 * erroutc.adb (Output_Msg_Text): Do Warnings_Treated_As_Errors
204 processing and [warning-as-error] modification for style
205 messages. Clean up code, simplify, remove unnecessary block
206 statement, add renaming of table entry.
207 * erroutc.ads (Warning_Treated_As_Error): Fix comment: no such
208 thing as Set_Warning_As_Error.
209 * opt.ads: Clean up comments and move related declarations near
211 * par-prag.adb: Process Warning_As_Error. This is necessary
212 because many style warning happen during parsing.
213 * sem_prag.adb: Use new Acquire_Warning_Match_String.
214 * sem_util.ads, sem_util.adb (Acquire_Warning_Match_String): New
215 function shared by par-prag.adb and sem_prag.adb. Replaces the
216 procedure in sem_prag.adb. Avoid use of global variables.
217 * stringt.ads, stringt.adb (To_String): New function to convert

226 Add pragma Inline for Is_Loaded and alphabetize the list.
227 (Unit_Name_Table_Size): New constant.
228 (Unit_Name_Header_Num): New subtype.

230 (Unit_Names): New simple hash table.
231 (Init_Unit_Name): New procedure declaration.

236 (Remove_Unit): Unregister the name.
237 (Unit_Name_Hash): New function.
238 * lib-load.adb (Create_Dummy_Package_Unit): Call Init_Unit_Name.

240 the unit has already been loaded. Call Init_Unit_Name and then
241 Remove_Unit if the loading has failed.

269 documentation for GNAT.Command_Line.

302 on formal parameters of dispatching operations.
304 2019-08-19 Ed Schonberg <schonberg@adacore.com>

308 the body of another expression function,

315 2019-08-19 Bob Duff <duff@adacore.com>
317 * exp_attr.adb (Attribute_Valid): Correct the handling of
318 private types where the full type is modular. System.Address is
319 an example. Otherwise, we convert uncheckedly to a signed type,
320 so we get an incorrect range 0 .. -1, for which all values will
321 fail. The 'Valid attribute is illegal for such types, but we
322 generate such illegal attribute_references for 'Valid_Scalars,
323 and we generate 'Valid_Scalars when the -gnateV switch is used.
324 Rename Btyp --> PBtyp to avoid hiding the outer Btyp, which was
326 * libgnat/a-except.adb: Set the Exception_Raised component.
327 Otherwise, we have incorrect reads of invalid data.

348 units and have already been performed.

365 entry, its first paarameter must be out, in_out or

371 * exp_atag.ads, exp_atag.adb (Build_Inherit_Predefined_Prims):
372 Adding formal to specify how many predefined primitives are
373 inherited from the parent type.
374 * exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
375 (Make_Secondary_DT): Compute the number of predefined primitives
376 of all tagged types (including tagged types not defined at
377 library level). Previously we unconditionally relied on the
378 Max_Predef_Prims constant value when building the dispatch
379 tables of tagged types not defined at library level (thus
380 consuming more memory for their dispatch tables than required).
381 (Make_DT): Compute the number of predefined primitives that must
382 be inherited from their parent type when building the dispatch
383 tables of tagged types not defined at library level. Previously
384 we unconditionally relied on the Max_Predef_Prims constant value
385 when building the dispatch tables of tagged types not defined at
386 library level (thus copying more data than required from the
389 2019-08-19 Bob Duff <duff@adacore.com>
391 * sem_ch13.adb (Record_Hole_Check): Procedure to check for holes
392 that incudes processing type extensions. A type extension is
393 processed by first calling Record_Hole_Check recursively on the
394 parent type to compute the bit number after the last component
397 2019-08-19 Gary Dismukes <dismukes@adacore.com>
399 * checks.adb (Length_Mismatch_Info_Message): New function in
400 Selected_Length_Checks to return a message indicating the
401 element counts for the mismatched lengths for a failed
402 compile-time length check.
403 (Plural_Or_Singular_Ending): Support function in
404 Length_Mismatch_Info_Message to return either "" or "s", for
405 concatenating to the end of words.
406 (Selected_Length_Checks): Pass the result of
407 Length_Mismatch_Info_Message as an extra warning message to
408 Compile_Time_Constraint_Error to indicate the mismatched lengths
409 for a failed compile-time length check.
410 * sem_util.ads (Compile_Time_Constraint_Error): Add an optional
411 message formal (Extra_Msg), defaulted to the empty string.
412 * sem_util.adb (Compile_Time_Constraint_Error): Output an extra
413 message following the main warning message (when Extra_Msg is
414 not the empty string).
416 2019-08-19 Patrick Bernardi <bernardi@adacore.com>
418 * socket.c: Removed the redefinition of getaddrinfo, getnameinfo
419 and freeaddrinfo to internal VxWorks kernel calls because they
420 are, well, internal kernel calls and cannot be called from RTPs.
421 VxWorks provides the necessary components to call these routines

429 representing generic actual types.
431 2019-08-19 Ed Schonberg <schonberg@adacore.com>
433 * sem_warn.adb (Check_References, Generic_Body_Formal): When a
434 formal parameter of a generic subprogram is not referenced in
435 the body, place the corresponding warning on the corresponding
436 entity in the specification of the generic body, as is done for
437 non-generic subprograms.

464 parameter of the generic. Function used to decide whether a
465 function is a pledge function.

467 of a pledge function for the path borrowed by the first

548 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
549 in the comparison against the maximum number of instantiations.
551 2019-08-14 Ed Schonberg <schonberg@adacore.com>
553 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
554 involves a Ghost aspect it may have been replaced by a null
555 statement; use the original node to find next Rep_Item.
556 * repinfo.adb (List_Entities): Do not list an Ignored
557 Ghost_Entity, for which information may have been deleted.
559 2019-08-14 Bob Duff <duff@adacore.com>
561 * sem_prag.ads, sem_prag.adb
562 (Process_Compile_Time_Warning_Or_Error): In parameterless
563 version, improve detection of whether we are in a generic unit
564 to cover the case of an instance within a generic unit.
565 (Process_Compile_Time_Warning_Or_Error): Rename the
566 two-parameter version to be
567 Validate_Compile_Time_Warning_Or_Error, and do not export it.
568 Issue a warning if the condition is not known at compile time.
569 The key point is that the warning must be given only for pragmas
570 deferred to the back end, because the back end discovers
571 additional values that are known at compile time. Previous
572 changes in this ticket have enabled this by deferring to the
573 back end without checking for special cases such as 'Size.
574 (Validate_Compile_Time_Warning_Or_Error): Rename to be
575 Defer_Compile_Time_Warning_Error_To_BE.
576 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):

588 2019-08-14 Bob Duff <duff@adacore.com>
590 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
591 protected functions to get rid of spurious error. The
592 transformation done by this procedure triggers legality errors
593 in the generated code in this case.
595 2019-08-14 Bob Duff <duff@adacore.com>
597 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
598 processing to the back end in all cases where the pragma's
599 condition is not known at compile time during the front end
600 (except in generics), as opposed to detecting 'Size attributes
601 and the like. This ensures that we take advantage of whatever
602 can be compile-time known after running the back end, as opposed
603 to having the front end guess what the back end can do. Remove
604 a little duplicated code at the call site.
605 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
606 Elists while in Validate_Compile_Time_Warning_Errors, because it
607 does analysis and name resolution, which sometimes involves

626 (Node_Header_Num): New subtype.
627 (Node_Hash): New function.
628 (To_Pending_Instantiations): New hash table.
629 (Add_Inlined_Body): Bail out early for subprograms in the main
630 unit or subunit. Likewise if the Is_Called flag is set. If the
631 subprogram is an instance, invoke Add_Inlined_Instance. Call
632 Set_Is_Called earlier. If the subrogram is within an instance,
633 invoke Add_Inlined_Instance. Also deal with the case where the
634 call itself is within an instance.
635 (Add_Inlined_Instance): New procedure.
636 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
637 (Add_Pending_Instantiation): Move the defence against ludicruous
638 number of instantiations to here. When back-end inlining is
639 enabled, associate an instantiation with its index in table and
640 mark a few selected kinds of instantiations as always needed.
641 (Initialize): Set Backend_Instances to No_Elist.
642 (Instantiate_Body): New procedure doing the work extracted
644 (Instantiate_Bodies): ...here. When back-end inlining is
645 enabled, loop over Called_Pending_Instantiations instead of
646 Pending_Instantiations.
647 (Is_Nested): Minor tweak.
648 (List_Inlining_Info): Also list the contents of
650 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
651 is set and otherwise set it before returning true.
652 (Analyze_Package_Instantiation): Remove the defence against
653 ludicruous number of instantiations. Invoke
654 Remove_Dead_Instance instead of doing the removal manually if
655 there is a guaranteed ABE.
657 2019-08-14 Gary Dismukes <dismukes@adacore.com>
659 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
660 of an interface type, create an expression function (that
661 returns False) rather than declaring an abstract function.

664 for inherited operations.
666 2019-08-14 Bob Duff <duff@adacore.com>

678 2019-08-14 Bob Duff <duff@adacore.com>
680 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
681 warning to the Sloc of the first pragma argument, rather than to
682 the pragma itself. This is to make pragmas processed after the
683 back end use the same Sloc as pragmas processed earlier, in the
684 front end. There's no reason for this discrepancy, and it
685 hinders further work on this ticket.
687 2019-08-14 Bob Duff <duff@adacore.com>
689 * sem.ads (Inside_A_Generic): Remove the ??? comment.

766 expression includes the implicit declaration of the loop
767 parameter. When a quantified expression is copied during
768 expansion, for example when building the precondition code from
769 the generated pragma, a new loop parameter must be created for

1384 'Valid as a replacement for a range check on a discrete type
1385 when the bounds of the range are given by type conversions,
1386 because in such a case there are distinct types involved and the
1387 subbested attribute replacement would be misplaced.
1389 2019-07-22 Yannick Moy <moy@adacore.com>

1429 * sem_res.adb (Resolve_Actuals): Replace code that displaces the

1453 libgnat/s-valwch.ads: Change categorization of packages that
1454 implement attribute 'Value from Pure to Preelaborate, to prevent
1455 undesirable optimizations when the evaluation of the attribute
1456 raises Constraint_Error, but subsequent use of the result of

1476 the worst case all the literals of the enumeration type would be
1477 single letter literals and the Table built by the frontend would
1478 have as many components as the length of the names string. As a
1479 result of this enhancement, the internal tables declared using
1480 Index_Table have a length closer to the real needs, thus
1481 avoiding the declaration of large arrays on 32-bit CCG targets.
