40 * sem_prag.adb (Analyze_Pragma): Modify handling of pragma
41 Max_Entry_Queue_Length to not reject integer values of negative
43 * sem_util.adb (Get_Max_Queue_Length): Add processing for values
44 of negative one to fit within the current scheme.
46 2019-08-20 Arnaud Charlet <charlet@adacore.com>
48 * exp_unst.adb (Unnest_Subprograms, Unnest_Subprogram): Take
49 inlining (-gnatn) into account.
51 2019-08-20 Ed Schonberg <schonberg@adacore.com>
53 * exp_ch13.adb (Expand_N_Attribute_Definition_Clause, case
54 Storage_Size): If the expression for Storage_Size is not static
55 it may depend on characterstics of another type that may bot be
56 frozen yet, so the elaboration of the expression for the aspect
57 must be attached directly to the freeze actions of the type to

63 entity of the generated Default_Initial_Condition procedure in
64 order to construct a proper entity chain.
66 2019-08-20 Yannick Moy <moy@adacore.com>
68 * exp_spark.adb (Expand_SPARK_N_Slice_Or_Indexed_Component):
69 Renaming of function to apply to slices as well.
70 (Expand_SPARK): Expand prefix of slices of access type.
72 2019-08-20 Bob Duff <duff@adacore.com>
74 * exp_aggr.adb (Expand_Array_Aggregate): Use build-in-place in
75 the nonlimited case in STEP 4. This improves the efficiency of
76 things like (1 .. 1000 => <>). We still generate some code for
77 that, unfortunately, but it is much improved.
78 (Aggr_Assignment_OK_For_Backend): Return false if <> components
81 2019-08-20 Bob Duff <duff@adacore.com>
83 * exp_ch6.adb (Needs_BIP_Alloc_Form): Call
84 Requires_Transient_Scope rather than checking constrainedness
85 and so forth. We have previously improved
86 Requires_Transient_Scope to return False in various cases,
87 notably a limited record with an access discriminant. This
88 change takes advantage of that to avoid using the secondary
89 stack for functions returning such types.
90 (Make_Build_In_Place_Call_In_Allocator): Be consistent by
91 calling Needs_BIP_Alloc_Form rather than Is_Constrained and so
93 * sem_ch4.adb (Analyze_Allocator): The above change causes the
94 compiler to generate code that is not legal Ada, in particular
95 an uninitialized allocator for indefinite subtype. This is
96 harmless, so we suppress the error message in this case.

124 * exp_attr.adb (Expand_Loop_Entry_Attribute): When expanding a
125 loop entry attribute for a while_loop we construct a function
126 that incorporates the expanded condition of the loop. The itypes
127 that may be generated in that expansion must carry the scope of
128 the constructed function for proper handling in gigi.
130 2019-08-20 Ed Schonberg <schonberg@adacore.com>
132 * exp_disp.adb (Build_Class_Wide_Check, Replace_Formals): When a
133 dispatching call tp a subprogram with a class-wide precondition
134 occurrs in the same declarative part as the ancestor subprogram
135 being called, the`expression for the precondition has not been
136 analyzed yet. Such a call may appear, e.g. in an expression
137 function. In that case, the replacement of formals by actuals in
138 the call cannot use the formal entities of the subprogram being
139 called, and the occurrence of the formals in the expression must
140 be located by name (Chars fields) as would be done at a later
141 freeze point, when the expression is resolved in the context of
142 the subprogram itself.
144 2019-08-20 Bob Duff <duff@adacore.com>
146 * sem_prag.adb (Persistent_BSS): If an initialization is present
147 because of Initialize_Scalars or Normalize_Scalars, generate an
148 implicit pragma Suppress_Initialization to remove that, because
149 initialization is not allowed for these variables. Other
150 initializations remain illegal.
152 2019-08-20 Gary Dismukes <dismukes@adacore.com>
154 * sem_ch3.adb (OK_For_Limited_Init_In_05): In the case of type
155 conversions, apply the recursive call to the Original_Node of
156 the expression Exp rather than the Expression of the
157 Original_Node, in the case where Exp has been rewritten;
158 otherwise, when Original_Node is the same as Exp, apply the
159 recursive call to the Expression.
160 (Check_Initialization): Revise condition for special check on
161 type conversions of limited function calls to test Original_Node
162 (avoiding spurious errors on expanded unchecked conversions
163 applied to build-in-place dispatching calls).
165 2019-08-20 Patrick Bernardi <bernardi@adacore.com>
167 * exp_aggr.adb (Expand_Record_Aggregate): Always convert a
168 record Aggregate to assignment statements if the option
169 Aggregate_Individually_Assign is set.

185 2019-08-20 Bob Duff <duff@adacore.com>
187 * freeze.adb (Is_Atomic_VFA_Aggregate): Make the temp for
188 initialization of the atomic variable be constant. This is
189 cleaner, and might improve efficiency.

198 * sem_eval.adb (Expr_Value): Implement the case of an unchecked
199 conversion of a static expression.
201 2019-08-20 Bob Duff <duff@adacore.com>
203 * sem_ch13.adb (Is_Null_Array): New function, used to detect the
204 null array case; used to warn about uncheckedly converting to a
205 zero-sized array. It is unfortunate that we can't just check
206 the size, and warn on all cases of converting from a
207 nonzero-sized type to a zero-sized one. That's because "0" means
208 two different things: "size is zero" and "size is unknown".
209 Until we fix that design flaw, we need this more targeted fix.
211 2019-08-20 Bob Duff <duff@adacore.com>
213 * libgnat/a-cborma.adb, libgnat/a-cborse.adb (Clear): Repeatedly

215 substantially speeds up future Delete operations.

226 2019-08-20 Bob Duff <duff@adacore.com>
228 * sem_ch13.adb (Object_Size): Give an error for zero. It really
229 rubs me the wrong way that we don't honor "for T'Object_Size use
230 0;", but it's not important enough to fix. In any case, if we're
231 not going to obey the clause, we should give an error.

242 thing as Set_Warning_As_Error.
243 * opt.ads: Clean up comments and move related declarations near
245 * par-prag.adb: Process Warning_As_Error. This is necessary
246 because many style warning happen during parsing.
247 * sem_prag.adb: Use new Acquire_Warning_Match_String.
248 * sem_util.ads, sem_util.adb (Acquire_Warning_Match_String): New
249 function shared by par-prag.adb and sem_prag.adb. Replaces the
250 procedure in sem_prag.adb. Avoid use of global variables.

349 2019-08-19 Bob Duff <duff@adacore.com>
351 * exp_attr.adb (Attribute_Valid): Correct the handling of
352 private types where the full type is modular. System.Address is
353 an example. Otherwise, we convert uncheckedly to a signed type,
354 so we get an incorrect range 0 .. -1, for which all values will
355 fail. The 'Valid attribute is illegal for such types, but we
356 generate such illegal attribute_references for 'Valid_Scalars,
357 and we generate 'Valid_Scalars when the -gnateV switch is used.
358 Rename Btyp --> PBtyp to avoid hiding the outer Btyp, which was
360 * libgnat/a-except.adb: Set the Exception_Raised component.
361 Otherwise, we have incorrect reads of invalid data.

406 Adding formal to specify how many predefined primitives are
407 inherited from the parent type.
408 * exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
409 (Make_Secondary_DT): Compute the number of predefined primitives
410 of all tagged types (including tagged types not defined at
411 library level). Previously we unconditionally relied on the
412 Max_Predef_Prims constant value when building the dispatch
413 tables of tagged types not defined at library level (thus
414 consuming more memory for their dispatch tables than required).
415 (Make_DT): Compute the number of predefined primitives that must
416 be inherited from their parent type when building the dispatch
417 tables of tagged types not defined at library level. Previously
418 we unconditionally relied on the Max_Predef_Prims constant value
419 when building the dispatch tables of tagged types not defined at
420 library level (thus copying more data than required from the
423 2019-08-19 Bob Duff <duff@adacore.com>
425 * sem_ch13.adb (Record_Hole_Check): Procedure to check for holes
426 that incudes processing type extensions. A type extension is
427 processed by first calling Record_Hole_Check recursively on the
428 parent type to compute the bit number after the last component
431 2019-08-19 Gary Dismukes <dismukes@adacore.com>
433 * checks.adb (Length_Mismatch_Info_Message): New function in
434 Selected_Length_Checks to return a message indicating the
435 element counts for the mismatched lengths for a failed
436 compile-time length check.
437 (Plural_Or_Singular_Ending): Support function in
438 Length_Mismatch_Info_Message to return either "" or "s", for
439 concatenating to the end of words.
440 (Selected_Length_Checks): Pass the result of
441 Length_Mismatch_Info_Message as an extra warning message to
442 Compile_Time_Constraint_Error to indicate the mismatched lengths
443 for a failed compile-time length check.
444 * sem_util.ads (Compile_Time_Constraint_Error): Add an optional
445 message formal (Extra_Msg), defaulted to the empty string.
446 * sem_util.adb (Compile_Time_Constraint_Error): Output an extra
447 message following the main warning message (when Extra_Msg is
448 not the empty string).
450 2019-08-19 Patrick Bernardi <bernardi@adacore.com>
452 * socket.c: Removed the redefinition of getaddrinfo, getnameinfo
453 and freeaddrinfo to internal VxWorks kernel calls because they
454 are, well, internal kernel calls and cannot be called from RTPs.
455 VxWorks provides the necessary components to call these routines

463 representing generic actual types.
465 2019-08-19 Ed Schonberg <schonberg@adacore.com>
467 * sem_warn.adb (Check_References, Generic_Body_Formal): When a
468 formal parameter of a generic subprogram is not referenced in
469 the body, place the corresponding warning on the corresponding
470 entity in the specification of the generic body, as is done for
471 non-generic subprograms.

499 function is a pledge function.
500 (Check_Not_Borrowed): Disable check inside the second parameter
501 of a pledge function for the path borrowed by the first

553 Elements attribute of Container.
554 (Content_Init): New subprogram. It is used to initialize the
555 Base attribute of Container.
556 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
557 resize the underlying array of a container if necessary.
558 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,
559 Union): Update to match changes in type declarations.
560 (Add): Modify body to damp the time and space cost in a specific

577 * inline.adb (Add_Pending_Instantiation): Fix off-by-one error
578 in the comparison against the maximum number of instantiations.
580 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
582 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
583 in the comparison against the maximum number of instantiations.
585 2019-08-14 Ed Schonberg <schonberg@adacore.com>

588 involves a Ghost aspect it may have been replaced by a null
589 statement; use the original node to find next Rep_Item.
590 * repinfo.adb (List_Entities): Do not list an Ignored
591 Ghost_Entity, for which information may have been deleted.
593 2019-08-14 Bob Duff <duff@adacore.com>
595 * sem_prag.ads, sem_prag.adb
596 (Process_Compile_Time_Warning_Or_Error): In parameterless
597 version, improve detection of whether we are in a generic unit
598 to cover the case of an instance within a generic unit.
599 (Process_Compile_Time_Warning_Or_Error): Rename the
600 two-parameter version to be
601 Validate_Compile_Time_Warning_Or_Error, and do not export it.
602 Issue a warning if the condition is not known at compile time.
603 The key point is that the warning must be given only for pragmas
604 deferred to the back end, because the back end discovers
605 additional values that are known at compile time. Previous
606 changes in this ticket have enabled this by deferring to the
607 back end without checking for special cases such as 'Size.
608 (Validate_Compile_Time_Warning_Or_Error): Rename to be
609 Defer_Compile_Time_Warning_Error_To_BE.
610 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):

622 2019-08-14 Bob Duff <duff@adacore.com>
624 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
625 protected functions to get rid of spurious error. The
626 transformation done by this procedure triggers legality errors
627 in the generated code in this case.
629 2019-08-14 Bob Duff <duff@adacore.com>
631 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
632 processing to the back end in all cases where the pragma's
633 condition is not known at compile time during the front end
634 (except in generics), as opposed to detecting 'Size attributes
635 and the like. This ensures that we take advantage of whatever
636 can be compile-time known after running the back end, as opposed
637 to having the front end guess what the back end can do. Remove
638 a little duplicated code at the call site.
639 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
640 Elists while in Validate_Compile_Time_Warning_Errors, because it
641 does analysis and name resolution, which sometimes involves

661 (Node_Hash): New function.
662 (To_Pending_Instantiations): New hash table.
663 (Add_Inlined_Body): Bail out early for subprograms in the main
664 unit or subunit. Likewise if the Is_Called flag is set. If the
665 subprogram is an instance, invoke Add_Inlined_Instance. Call
666 Set_Is_Called earlier. If the subrogram is within an instance,
667 invoke Add_Inlined_Instance. Also deal with the case where the
668 call itself is within an instance.
669 (Add_Inlined_Instance): New procedure.
670 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
671 (Add_Pending_Instantiation): Move the defence against ludicruous
672 number of instantiations to here. When back-end inlining is
673 enabled, associate an instantiation with its index in table and
674 mark a few selected kinds of instantiations as always needed.
675 (Initialize): Set Backend_Instances to No_Elist.
676 (Instantiate_Body): New procedure doing the work extracted
678 (Instantiate_Bodies): ...here. When back-end inlining is
679 enabled, loop over Called_Pending_Instantiations instead of
680 Pending_Instantiations.
681 (Is_Nested): Minor tweak.
682 (List_Inlining_Info): Also list the contents of
684 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
685 is set and otherwise set it before returning true.
686 (Analyze_Package_Instantiation): Remove the defence against
687 ludicruous number of instantiations. Invoke
688 Remove_Dead_Instance instead of doing the removal manually if
689 there is a guaranteed ABE.
691 2019-08-14 Gary Dismukes <dismukes@adacore.com>
693 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
694 of an interface type, create an expression function (that
695 returns False) rather than declaring an abstract function.

698 for inherited operations.
700 2019-08-14 Bob Duff <duff@adacore.com>

710 documentation of gnatelim.
712 2019-08-14 Bob Duff <duff@adacore.com>
714 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
715 warning to the Sloc of the first pragma argument, rather than to
716 the pragma itself. This is to make pragmas processed after the
717 back end use the same Sloc as pragmas processed earlier, in the
718 front end. There's no reason for this discrepancy, and it
719 hinders further work on this ticket.
721 2019-08-14 Bob Duff <duff@adacore.com>
723 * sem.ads (Inside_A_Generic): Remove the ??? comment.

800 expression includes the implicit declaration of the loop
801 parameter. When a quantified expression is copied during
802 expansion, for example when building the precondition code from
803 the generated pragma, a new loop parameter must be created for
804 the new tree, to prevent duplicate declarations for the same

889 component is an access to a class-wide type and the type of the
890 context is an access to a tagged type the relevant type is that
891 of the component (since in such case we may need to generate

1097 to generate proper checks when an actual for an in-out or out
1098 parameter has a non-null access type. No constraints are

1418 'Valid as a replacement for a range check on a discrete type
1419 when the bounds of the range are given by type conversions,
1420 because in such a case there are distinct types involved and the
1421 subbested attribute replacement would be misplaced.
1423 2019-07-22 Yannick Moy <moy@adacore.com>
1425 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,
1426 Is_Subpath_Expression): Add parameter Is_Traversal to adapt

1463 * sem_res.adb (Resolve_Actuals): Replace code that displaces the

1487 libgnat/s-valwch.ads: Change categorization of packages that
1488 implement attribute 'Value from Pure to Preelaborate, to prevent
1489 undesirable optimizations when the evaluation of the attribute
1490 raises Constraint_Error, but subsequent use of the result of
1491 this evsaluation is removed by a subsequent optimization.

1508 Image_Enumeration_16, Image_Enumeration_32): Define the index of
1509 Index_Table with range Natural'First .. Names'Length since in
1510 the worst case all the literals of the enumeration type would be
1511 single letter literals and the Table built by the frontend would
1512 have as many components as the length of the names string. As a
1513 result of this enhancement, the internal tables declared using
1514 Index_Table have a length closer to the real needs, thus
1515 avoiding the declaration of large arrays on 32-bit CCG targets.

1552 * sem_ch3.adb (Convert_Bound): Subsidiary of
1553 Floating_Point_Type_Declaration, to handle properly range
