8 2019-08-21 Javier Miranda <miranda@adacore.com>

16 * doc/Makefile (mk_empty_dirs): New (PHONY) rule.

23 documentation to reflect expected behavior.

25 * sem_prag.adb (Analyze_Pragma): Modify handling of pragma
26 Max_Entry_Queue_Length to not reject integer values of negative
28 * sem_util.adb (Get_Max_Queue_Length): Add processing for values
29 of negative one to fit within the current scheme.
31 2019-08-20 Arnaud Charlet <charlet@adacore.com>
33 * exp_unst.adb (Unnest_Subprograms, Unnest_Subprogram): Take
34 inlining (-gnatn) into account.
36 2019-08-20 Ed Schonberg <schonberg@adacore.com>
38 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case
39 Storage_Size): If the expression for Storage_Size is not static
40 it may depend on characterstics of another type that may bot be
41 frozen yet, so the elaboration of the expression for the aspect
42 must be attached directly to the freeze actions of the type to
45 2019-08-20 Piotr Trojanek <trojanek@adacore.com>
47 * exp_util.adb (Build_DIC_Procedure_Declaration): Set the last
48 entity of the generated Default_Initial_Condition procedure in
49 order to construct a proper entity chain.
51 2019-08-20 Yannick Moy <moy@adacore.com>
53 * exp_spark.adb (Expand_SPARK_N_Slice_Or_Indexed_Component):
54 Renaming of function to apply to slices as well.
55 (Expand_SPARK): Expand prefix of slices of access type.
57 2019-08-20 Bob Duff <duff@adacore.com>
59 * exp_aggr.adb (Expand_Array_Aggregate): Use build-in-place in
60 the nonlimited case in STEP 4. This improves the efficiency of
61 things like (1 .. 1000 => <>). We still generate some code for
62 that, unfortunately, but it is much improved.
63 (Aggr_Assignment_OK_For_Backend): Return false if <> components
66 2019-08-20 Bob Duff <duff@adacore.com>
68 * exp_ch6.adb (Needs_BIP_Alloc_Form): Call
69 Requires_Transient_Scope rather than checking constrainedness
70 and so forth. We have previously improved
71 Requires_Transient_Scope to return False in various cases,
72 notably a limited record with an access discriminant. This
73 change takes advantage of that to avoid using the secondary
74 stack for functions returning such types.
75 (Make_Build_In_Place_Call_In_Allocator): Be consistent by
76 calling Needs_BIP_Alloc_Form rather than Is_Constrained and so
78 * sem_ch4.adb (Analyze_Allocator): The above change causes the
79 compiler to generate code that is not legal Ada, in particular
80 an uninitialized allocator for indefinite subtype. This is
81 harmless, so we suppress the error message in this case.

107 2019-08-20 Ed Schonberg <schonberg@adacore.com>
109 * exp_attr.adb (Expand_Loop_Entry_Attribute): When expanding a
110 loop entry attribute for a while_loop we construct a function
111 that incorporates the expanded condition of the loop. The itypes
112 that may be generated in that expansion must carry the scope of
113 the constructed function for proper handling in gigi.
115 2019-08-20 Ed Schonberg <schonberg@adacore.com>
117 * exp_disp.adb (Build_Class_Wide_Check, Replace_Formals): When a
118 dispatching call tp a subprogram with a class-wide precondition
119 occurrs in the same declarative part as the ancestor subprogram
120 being called, the`expression for the precondition has not been
121 analyzed yet. Such a call may appear, e.g. in an expression
122 function. In that case, the replacement of formals by actuals in
123 the call cannot use the formal entities of the subprogram being
124 called, and the occurrence of the formals in the expression must
125 be located by name (Chars fields) as would be done at a later
126 freeze point, when the expression is resolved in the context of
127 the subprogram itself.
129 2019-08-20 Bob Duff <duff@adacore.com>
131 * sem_prag.adb (Persistent_BSS): If an initialization is present
132 because of Initialize_Scalars or Normalize_Scalars, generate an
133 implicit pragma Suppress_Initialization to remove that, because
134 initialization is not allowed for these variables. Other
135 initializations remain illegal.
137 2019-08-20 Gary Dismukes <dismukes@adacore.com>
139 * sem_ch3.adb (OK_For_Limited_Init_In_05): In the case of type
140 conversions, apply the recursive call to the Original_Node of
141 the expression Exp rather than the Expression of the
142 Original_Node, in the case where Exp has been rewritten;
143 otherwise, when Original_Node is the same as Exp, apply the
144 recursive call to the Expression.
145 (Check_Initialization): Revise condition for special check on
146 type conversions of limited function calls to test Original_Node
147 (avoiding spurious errors on expanded unchecked conversions
148 applied to build-in-place dispatching calls).
150 2019-08-20 Patrick Bernardi <bernardi@adacore.com>
152 * exp_aggr.adb (Expand_Record_Aggregate): Always convert a
153 record Aggregate to assignment statements if the option
154 Aggregate_Individually_Assign is set.
155 * opt.ads (Aggregate_Individually_Assign): New option.
156 * par-prag.adb (Prag): Add Pragma_Aggregate_Individually_Assign.
157 * sem_prag.adb (Analyze_Pragma): Likewise.
158 * snames.ads-tmpl: Add Pragma_Aggregate_Individually_Assign and
159 Name_Aggregate_Individually_Assign.

168 versions prior to Ada 2020.
170 2019-08-20 Bob Duff <duff@adacore.com>
172 * freeze.adb (Is_Atomic_VFA_Aggregate): Make the temp for
173 initialization of the atomic variable be constant. This is
174 cleaner, and might improve efficiency.
176 2019-08-20 Eric Botcazou <ebotcazou@adacore.com>
178 * repinfo.adb (List_Record_Info): In -gnatR4 mode, set the
179 relevant flag on the implicit base type of a record subtype.
181 2019-08-20 Bob Duff <duff@adacore.com>
183 * sem_eval.adb (Expr_Value): Implement the case of an unchecked
184 conversion of a static expression.
186 2019-08-20 Bob Duff <duff@adacore.com>
188 * sem_ch13.adb (Is_Null_Array): New function, used to detect the
189 null array case; used to warn about uncheckedly converting to a
190 zero-sized array. It is unfortunate that we can't just check
191 the size, and warn on all cases of converting from a
192 nonzero-sized type to a zero-sized one. That's because "0" means
193 two different things: "size is zero" and "size is unknown".
194 Until we fix that design flaw, we need this more targeted fix.
196 2019-08-20 Bob Duff <duff@adacore.com>
198 * libgnat/a-cborma.adb, libgnat/a-cborse.adb (Clear): Repeatedly
199 call Delete. This avoids clearing the free list, which
200 substantially speeds up future Delete operations.
202 2019-08-20 Bob Duff <duff@adacore.com>
204 * sem_ch13.adb (Component_Order_Check): New procedure to check

211 2019-08-20 Bob Duff <duff@adacore.com>
213 * sem_ch13.adb (Object_Size): Give an error for zero. It really
214 rubs me the wrong way that we don't honor "for T'Object_Size use
215 0;", but it's not important enough to fix. In any case, if we're
216 not going to obey the clause, we should give an error.
218 2019-08-20 Bob Duff <duff@adacore.com>
220 * errout.adb (Error_Msg_Internal): Set Warn_Err in case of
222 * erroutc.adb (Output_Msg_Text): Do Warnings_Treated_As_Errors
223 processing and [warning-as-error] modification for style
224 messages. Clean up code, simplify, remove unnecessary block
225 statement, add renaming of table entry.
226 * erroutc.ads (Warning_Treated_As_Error): Fix comment: no such
227 thing as Set_Warning_As_Error.
228 * opt.ads: Clean up comments and move related declarations near
230 * par-prag.adb: Process Warning_As_Error. This is necessary
231 because many style warning happen during parsing.
232 * sem_prag.adb: Use new Acquire_Warning_Match_String.
233 * sem_util.ads, sem_util.adb (Acquire_Warning_Match_String): New
234 function shared by par-prag.adb and sem_prag.adb. Replaces the
235 procedure in sem_prag.adb. Avoid use of global variables.
236 * stringt.ads, stringt.adb (To_String): New function to convert

254 (Is_Loaded): Reimplement using a lookup in the names table.
255 (Remove_Unit): Unregister the name.
256 (Unit_Name_Hash): New function.
257 * lib-load.adb (Create_Dummy_Package_Unit): Call Init_Unit_Name.
258 (Load_Unit): Use a lookup in the names table to find out whether
259 the unit has already been loaded. Call Init_Unit_Name and then
260 Remove_Unit if the loading has failed.

327 the body of another expression function,

334 2019-08-19 Bob Duff <duff@adacore.com>
336 * exp_attr.adb (Attribute_Valid): Correct the handling of
337 private types where the full type is modular. System.Address is
338 an example. Otherwise, we convert uncheckedly to a signed type,
339 so we get an incorrect range 0 .. -1, for which all values will
340 fail. The 'Valid attribute is illegal for such types, but we
341 generate such illegal attribute_references for 'Valid_Scalars,
342 and we generate 'Valid_Scalars when the -gnateV switch is used.
343 Rename Btyp --> PBtyp to avoid hiding the outer Btyp, which was
345 * libgnat/a-except.adb: Set the Exception_Raised component.
346 Otherwise, we have incorrect reads of invalid data.

367 units and have already been performed.

390 * exp_atag.ads, exp_atag.adb (Build_Inherit_Predefined_Prims):
391 Adding formal to specify how many predefined primitives are
392 inherited from the parent type.
393 * exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
394 (Make_Secondary_DT): Compute the number of predefined primitives
395 of all tagged types (including tagged types not defined at
396 library level). Previously we unconditionally relied on the
397 Max_Predef_Prims constant value when building the dispatch
398 tables of tagged types not defined at library level (thus
399 consuming more memory for their dispatch tables than required).
400 (Make_DT): Compute the number of predefined primitives that must
401 be inherited from their parent type when building the dispatch
402 tables of tagged types not defined at library level. Previously
403 we unconditionally relied on the Max_Predef_Prims constant value
404 when building the dispatch tables of tagged types not defined at
405 library level (thus copying more data than required from the
408 2019-08-19 Bob Duff <duff@adacore.com>
410 * sem_ch13.adb (Record_Hole_Check): Procedure to check for holes
411 that incudes processing type extensions. A type extension is
412 processed by first calling Record_Hole_Check recursively on the
413 parent type to compute the bit number after the last component
416 2019-08-19 Gary Dismukes <dismukes@adacore.com>
418 * checks.adb (Length_Mismatch_Info_Message): New function in
419 Selected_Length_Checks to return a message indicating the
420 element counts for the mismatched lengths for a failed
421 compile-time length check.
422 (Plural_Or_Singular_Ending): Support function in
423 Length_Mismatch_Info_Message to return either "" or "s", for
424 concatenating to the end of words.
425 (Selected_Length_Checks): Pass the result of
426 Length_Mismatch_Info_Message as an extra warning message to
427 Compile_Time_Constraint_Error to indicate the mismatched lengths
428 for a failed compile-time length check.
429 * sem_util.ads (Compile_Time_Constraint_Error): Add an optional
430 message formal (Extra_Msg), defaulted to the empty string.
431 * sem_util.adb (Compile_Time_Constraint_Error): Output an extra
432 message following the main warning message (when Extra_Msg is
433 not the empty string).
435 2019-08-19 Patrick Bernardi <bernardi@adacore.com>
437 * socket.c: Removed the redefinition of getaddrinfo, getnameinfo
438 and freeaddrinfo to internal VxWorks kernel calls because they
439 are, well, internal kernel calls and cannot be called from RTPs.
440 VxWorks provides the necessary components to call these routines

448 representing generic actual types.
450 2019-08-19 Ed Schonberg <schonberg@adacore.com>
452 * sem_warn.adb (Check_References, Generic_Body_Formal): When a
453 formal parameter of a generic subprogram is not referenced in
454 the body, place the corresponding warning on the corresponding
455 entity in the specification of the generic body, as is done for
456 non-generic subprograms.

483 parameter of the generic. Function used to decide whether a
484 function is a pledge function.

537 Container. Add a type Array_Base which replaces the previous
538 Elements attribute of Container.
539 (Content_Init): New subprogram. It is used to initialize the
540 Base attribute of Container.
541 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
542 resize the underlying array of a container if necessary.
543 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,

562 * inline.adb (Add_Pending_Instantiation): Fix off-by-one error
563 in the comparison against the maximum number of instantiations.
565 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
567 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
568 in the comparison against the maximum number of instantiations.

574 statement; use the original node to find next Rep_Item.
575 * repinfo.adb (List_Entities): Do not list an Ignored
576 Ghost_Entity, for which information may have been deleted.
578 2019-08-14 Bob Duff <duff@adacore.com>
580 * sem_prag.ads, sem_prag.adb
581 (Process_Compile_Time_Warning_Or_Error): In parameterless
582 version, improve detection of whether we are in a generic unit
583 to cover the case of an instance within a generic unit.
584 (Process_Compile_Time_Warning_Or_Error): Rename the
585 two-parameter version to be
586 Validate_Compile_Time_Warning_Or_Error, and do not export it.
587 Issue a warning if the condition is not known at compile time.
588 The key point is that the warning must be given only for pragmas
589 deferred to the back end, because the back end discovers
590 additional values that are known at compile time. Previous
591 changes in this ticket have enabled this by deferring to the
592 back end without checking for special cases such as 'Size.
593 (Validate_Compile_Time_Warning_Or_Error): Rename to be
594 Defer_Compile_Time_Warning_Error_To_BE.
595 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):

607 2019-08-14 Bob Duff <duff@adacore.com>
609 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
610 protected functions to get rid of spurious error. The
611 transformation done by this procedure triggers legality errors
612 in the generated code in this case.
614 2019-08-14 Bob Duff <duff@adacore.com>
616 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
617 processing to the back end in all cases where the pragma's
618 condition is not known at compile time during the front end
619 (except in generics), as opposed to detecting 'Size attributes
620 and the like. This ensures that we take advantage of whatever
621 can be compile-time known after running the back end, as opposed
622 to having the front end guess what the back end can do. Remove
623 a little duplicated code at the call site.
624 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
625 Elists while in Validate_Compile_Time_Warning_Errors, because it
626 does analysis and name resolution, which sometimes involves

645 (Node_Header_Num): New subtype.
646 (Node_Hash): New function.
647 (To_Pending_Instantiations): New hash table.
648 (Add_Inlined_Body): Bail out early for subprograms in the main
649 unit or subunit. Likewise if the Is_Called flag is set. If the
650 subprogram is an instance, invoke Add_Inlined_Instance. Call
651 Set_Is_Called earlier. If the subrogram is within an instance,
652 invoke Add_Inlined_Instance. Also deal with the case where the
653 call itself is within an instance.
654 (Add_Inlined_Instance): New procedure.
655 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
656 (Add_Pending_Instantiation): Move the defence against ludicruous
657 number of instantiations to here. When back-end inlining is
658 enabled, associate an instantiation with its index in table and
659 mark a few selected kinds of instantiations as always needed.
660 (Initialize): Set Backend_Instances to No_Elist.
661 (Instantiate_Body): New procedure doing the work extracted
663 (Instantiate_Bodies): ...here. When back-end inlining is
664 enabled, loop over Called_Pending_Instantiations instead of
665 Pending_Instantiations.
666 (Is_Nested): Minor tweak.
667 (List_Inlining_Info): Also list the contents of
669 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
670 is set and otherwise set it before returning true.
671 (Analyze_Package_Instantiation): Remove the defence against
672 ludicruous number of instantiations. Invoke
673 Remove_Dead_Instance instead of doing the removal manually if
674 there is a guaranteed ABE.
676 2019-08-14 Gary Dismukes <dismukes@adacore.com>
678 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
679 of an interface type, create an expression function (that
680 returns False) rather than declaring an abstract function.
681 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
682 False unconditionally at the start of the loop creating wrappers
683 for inherited operations.
685 2019-08-14 Bob Duff <duff@adacore.com>

697 2019-08-14 Bob Duff <duff@adacore.com>
699 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
700 warning to the Sloc of the first pragma argument, rather than to
701 the pragma itself. This is to make pragmas processed after the
702 back end use the same Sloc as pragmas processed earlier, in the
703 front end. There's no reason for this discrepancy, and it
704 hinders further work on this ticket.
706 2019-08-14 Bob Duff <duff@adacore.com>
708 * sem.ads (Inside_A_Generic): Remove the ??? comment.
710 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

785 expression includes the implicit declaration of the loop
786 parameter. When a quantified expression is copied during
787 expansion, for example when building the precondition code from
788 the generated pragma, a new loop parameter must be created for
789 the new tree, to prevent duplicate declarations for the same

874 component is an access to a class-wide type and the type of the
875 context is an access to a tagged type the relevant type is that

1403 'Valid as a replacement for a range check on a discrete type
1404 when the bounds of the range are given by type conversions,
1405 because in such a case there are distinct types involved and the
1406 subbested attribute replacement would be misplaced.
1408 2019-07-22 Yannick Moy <moy@adacore.com>

1472 libgnat/s-valwch.ads: Change categorization of packages that
1473 implement attribute 'Value from Pure to Preelaborate, to prevent
1474 undesirable optimizations when the evaluation of the attribute
1475 raises Constraint_Error, but subsequent use of the result of

1495 the worst case all the literals of the enumeration type would be
1496 single letter literals and the Table built by the frontend would
1497 have as many components as the length of the names string. As a
1498 result of this enhancement, the internal tables declared using
1499 Index_Table have a length closer to the real needs, thus
1500 avoiding the declaration of large arrays on 32-bit CCG targets.
