3 * sem_ch13.adb (Component_Order_Check): New procedure to check
4 for out-of-order clauses.
5 * warnsw.ads, warnsw.adb: New -gnatw_r switch.
6 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
8 * gnat_ugn.texi: Regenerate.
10 2019-08-20 Bob Duff <duff@adacore.com>
12 * sem_ch13.adb (Object_Size): Give an error for zero. It really
13 rubs me the wrong way that we don't honor "for T'Object_Size use
14 0;", but it's not important enough to fix. In any case, if we're
15 not going to obey the clause, we should give an error.
17 2019-08-20 Bob Duff <duff@adacore.com>
19 * errout.adb (Error_Msg_Internal): Set Warn_Err in case of
21 * erroutc.adb (Output_Msg_Text): Do Warnings_Treated_As_Errors
22 processing and [warning-as-error] modification for style
23 messages. Clean up code, simplify, remove unnecessary block
24 statement, add renaming of table entry.
25 * erroutc.ads (Warning_Treated_As_Error): Fix comment: no such
26 thing as Set_Warning_As_Error.
27 * opt.ads: Clean up comments and move related declarations near
29 * par-prag.adb: Process Warning_As_Error. This is necessary
30 because many style warning happen during parsing.
31 * sem_prag.adb: Use new Acquire_Warning_Match_String.
32 * sem_util.ads, sem_util.adb (Acquire_Warning_Match_String): New
33 function shared by par-prag.adb and sem_prag.adb. Replaces the
34 procedure in sem_prag.adb. Avoid use of global variables.
35 * stringt.ads, stringt.adb (To_String): New function to convert
37 * doc/gnat_rm/implementation_defined_pragmas.rst: Document the
39 * gnat_rm.texi: Regenerate.
41 2019-08-20 Eric Botcazou <ebotcazou@adacore.com>

46 (Unit_Name_Header_Num): New subtype.
47 (Unit_Name_Hash): New function declaration.
48 (Unit_Names): New simple hash table.
49 (Init_Unit_Name): New procedure declaration.
50 * lib.adb (Set_Unit_Name): Unregister the old name in the table,
51 if any, and then register the new name.
52 (Init_Unit_Name): New procedure.
53 (Is_Loaded): Reimplement using a lookup in the names table.
54 (Remove_Unit): Unregister the name.
55 (Unit_Name_Hash): New function.
56 * lib-load.adb (Create_Dummy_Package_Unit): Call Init_Unit_Name.
57 (Load_Unit): Use a lookup in the names table to find out whether
58 the unit has already been loaded. Call Init_Unit_Name and then
59 Remove_Unit if the loading has failed.
60 (Make_Child_Decl_Unit): Call Init_Unit_Name.
61 (Make_Instance_Unit): Likewise.
62 * lib-writ.adb (Ensure_System_Dependency): Likewise.
64 2019-08-20 Bob Duff <duff@adacore.com>

68 2019-08-20 Piotr Trojanek <trojanek@adacore.com>
70 * impunit.adb (Get_Kind_Of_Unit): Revert change for adapting
71 this routine for gnatprove.
73 2019-08-20 Arnaud Charlet <charlet@adacore.com>
75 * doc/gnat_rm/implementation_defined_pragmas.rst: Document
76 requirements for Pragma Lock_Free.
77 * gnat_rm.texi: Regenerate.
79 2019-08-20 Philippe Gil <gil@adacore.com>

86 * libgnat/g-comlin.ads (Exit_From_Command_Line): Fix
87 documentation for GNAT.Command_Line.
89 2019-08-20 Pierre-Marie de Rodat <derodat@adacore.com>

106 2019-08-19 Gary Dismukes <dismukes@adacore.com>
108 * einfo.ads (E_Function, E_Procedure): Update comments to
109 reflect that Renamed_Entity is also used for nongeneric
112 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
114 * sem_prag.adb (Is_Before_First_Decl): Deal with rewritten

125 freezes when expander is active, unless the call appears within
126 the body of another expression function,
128 2019-08-19 Dmitriy Anisimkov <anisimko@adacore.com>
130 * libgnat/s-os_lib.ads, libgnat/s-os_lib.adb (To_Ada, To_C): New
133 2019-08-19 Bob Duff <duff@adacore.com>
135 * exp_attr.adb (Attribute_Valid): Correct the handling of
136 private types where the full type is modular. System.Address is
137 an example. Otherwise, we convert uncheckedly to a signed type,
138 so we get an incorrect range 0 .. -1, for which all values will
139 fail. The 'Valid attribute is illegal for such types, but we
140 generate such illegal attribute_references for 'Valid_Scalars,
141 and we generate 'Valid_Scalars when the -gnateV switch is used.
142 Rename Btyp --> PBtyp to avoid hiding the outer Btyp, which was
144 * libgnat/a-except.adb: Set the Exception_Raised component.
145 Otherwise, we have incorrect reads of invalid data.
147 2019-08-19 Pierre-Marie de Rodat <derodat@adacore.com>
149 * libgnat/a-cgaaso.ads, libgnat/a-cgarso.ads,

162 * inline.adb (Add_Inlined_Body): Do not special-case instances
163 that are compilation units.
164 (Add_Pending_Instantiation): Likewise.
165 (Instantiate_Body): Skip instantiations that are compilation
166 units and have already been performed.
167 * sem_ch12.adb (Needs_Body_Instantiated): Do not special-case
168 instances that are compilation units.
169 (Load_Parent_Of_Generic): Be prepared for parent that is a
170 compilation unit but whose instantiation node has not been

176 Called_Pending_Instantiations.
178 2019-08-19 Ed Schonberg <schonberg@adacore.com>
180 * sem_ch6.adb (Check_Synchronized_Overriding): Complete
181 predicate that applies legality check in 9.4 (11.9/2): if an
182 inherited subprogram is implemented by a protected procedure or
183 entry, its first paarameter must be out, in_out or
186 2019-08-19 Javier Miranda <miranda@adacore.com>
189 * exp_atag.ads, exp_atag.adb (Build_Inherit_Predefined_Prims):
190 Adding formal to specify how many predefined primitives are
191 inherited from the parent type.
192 * exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
193 (Make_Secondary_DT): Compute the number of predefined primitives
194 of all tagged types (including tagged types not defined at
195 library level). Previously we unconditionally relied on the
196 Max_Predef_Prims constant value when building the dispatch
197 tables of tagged types not defined at library level (thus
198 consuming more memory for their dispatch tables than required).
199 (Make_DT): Compute the number of predefined primitives that must
200 be inherited from their parent type when building the dispatch
201 tables of tagged types not defined at library level. Previously
202 we unconditionally relied on the Max_Predef_Prims constant value
203 when building the dispatch tables of tagged types not defined at
204 library level (thus copying more data than required from the
207 2019-08-19 Bob Duff <duff@adacore.com>
209 * sem_ch13.adb (Record_Hole_Check): Procedure to check for holes
210 that incudes processing type extensions. A type extension is
211 processed by first calling Record_Hole_Check recursively on the
212 parent type to compute the bit number after the last component
215 2019-08-19 Gary Dismukes <dismukes@adacore.com>
217 * checks.adb (Length_Mismatch_Info_Message): New function in
218 Selected_Length_Checks to return a message indicating the
219 element counts for the mismatched lengths for a failed
220 compile-time length check.
221 (Plural_Or_Singular_Ending): Support function in
222 Length_Mismatch_Info_Message to return either "" or "s", for
223 concatenating to the end of words.
224 (Selected_Length_Checks): Pass the result of
225 Length_Mismatch_Info_Message as an extra warning message to
226 Compile_Time_Constraint_Error to indicate the mismatched lengths
227 for a failed compile-time length check.
228 * sem_util.ads (Compile_Time_Constraint_Error): Add an optional
229 message formal (Extra_Msg), defaulted to the empty string.
230 * sem_util.adb (Compile_Time_Constraint_Error): Output an extra
231 message following the main warning message (when Extra_Msg is
232 not the empty string).
234 2019-08-19 Patrick Bernardi <bernardi@adacore.com>
236 * socket.c: Removed the redefinition of getaddrinfo, getnameinfo
237 and freeaddrinfo to internal VxWorks kernel calls because they
238 are, well, internal kernel calls and cannot be called from RTPs.
239 VxWorks provides the necessary components to call these routines
242 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
244 * exp_dist.adb (Is_Generic_Actual_Subtype): New predicate.
245 (Build_From_Any_Call, Build_To_Any_Call, Build_TypeCode_Call):
246 Use it instead of Is_Generic_Actual_Type flag to detect subtypes
247 representing generic actual types.
249 2019-08-19 Ed Schonberg <schonberg@adacore.com>
251 * sem_warn.adb (Check_References, Generic_Body_Formal): When a
252 formal parameter of a generic subprogram is not referenced in
253 the body, place the corresponding warning on the corresponding
254 entity in the specification of the generic body, as is done for
255 non-generic subprograms.
257 2019-08-19 Bob Duff <duff@adacore.com>
259 * errout.ads (Size_Too_Small_Message): New constant.
260 * errout.adb, freeze.adb, sem_ch13.adb: Use it.
262 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
264 * exp_dist.adb (Build_Package_Stubs): Do not specifically visit
265 the declarations of an N_Subprogram_Instantiation node.

277 local variable if needed.
279 2019-08-19 Claire Dross <dross@adacore.com>
281 * sem_spark.ads, sem_spark.adb (Is_Pledge_Function): New
282 parameter of the generic. Function used to decide whether a
283 function is a pledge function.
284 (Check_Not_Borrowed): Disable check inside the second parameter
285 of a pledge function for the path borrowed by the first
286 parameter. Also disable checks for entities inside a Global

302 2019-08-19 Ed Schonberg <schonberg@adacore.com>
304 * sem_ch3.adb (Derived_Enumeration_Type): Do no freeze anonymous
305 base type if the bounds in the derived type declaration are
306 literals of the type.

319 a pending instantiation for the body of the package.
321 2019-08-19 Olivier Hainque <hainque@adacore.com>
323 * gcc-interface/trans.c (Acc_Loop_to_gnu): Return the openacc
324 BIND_EXPR node we have constructed on purpose. Remove unused
327 2019-08-19 Pierre-Marie de Rodat <derodat@adacore.com>
329 * gcc-interface/lang.opt (fdump-scos): Define.
330 * gcc-interface/misc.c (gnat_handle_option): Handle
333 2019-08-14 Joffrey Huguet <huguet@adacore.com>
335 * libgnat/a-cofuba.ads: Add a Length attribute to type
336 Container. Add a type Array_Base which replaces the previous
337 Elements attribute of Container.
338 (Content_Init): New subprogram. It is used to initialize the
339 Base attribute of Container.
340 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
341 resize the underlying array of a container if necessary.
342 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,
343 Union): Update to match changes in type declarations.
344 (Add): Modify body to damp the time and space cost in a specific
346 (Content_Init): New subprogram. It is used to initialize the
347 Base attribute of Container.
348 (Remove): Modify body to damp the time and space cost in a
351 2019-08-14 Bob Duff <duff@adacore.com>
353 * sem_ch13.adb (Get_Alignment_Value): Return 1 for Alignment 0,
354 and do not give an error.
355 * doc/gnat_rm/representation_clauses_and_pragmas.rst: Update the
356 corresponding documentation.
357 * gnat_rm.texi: Regenerate.
359 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
361 * inline.adb (Add_Pending_Instantiation): Fix off-by-one error
362 in the comparison against the maximum number of instantiations.
364 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
366 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
367 in the comparison against the maximum number of instantiations.
369 2019-08-14 Ed Schonberg <schonberg@adacore.com>
371 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
372 involves a Ghost aspect it may have been replaced by a null
373 statement; use the original node to find next Rep_Item.
374 * repinfo.adb (List_Entities): Do not list an Ignored
375 Ghost_Entity, for which information may have been deleted.
377 2019-08-14 Bob Duff <duff@adacore.com>
379 * sem_prag.ads, sem_prag.adb
380 (Process_Compile_Time_Warning_Or_Error): In parameterless
381 version, improve detection of whether we are in a generic unit
382 to cover the case of an instance within a generic unit.
383 (Process_Compile_Time_Warning_Or_Error): Rename the
384 two-parameter version to be
385 Validate_Compile_Time_Warning_Or_Error, and do not export it.
386 Issue a warning if the condition is not known at compile time.
387 The key point is that the warning must be given only for pragmas
388 deferred to the back end, because the back end discovers
389 additional values that are known at compile time. Previous
390 changes in this ticket have enabled this by deferring to the
391 back end without checking for special cases such as 'Size.
392 (Validate_Compile_Time_Warning_Or_Error): Rename to be
393 Defer_Compile_Time_Warning_Error_To_BE.
394 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):
395 Add new switches -gnatw_c and -gnatw_C to control the above
397 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
398 Document new switches.
399 * gnat_ugn.texi: Regenerate.
401 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
403 * sem_ch12.adb (Might_Inline_Subp): Rework comment and restrict
404 the shortcut based on Is_Inlined to the back-end inlining case.
406 2019-08-14 Bob Duff <duff@adacore.com>
408 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
409 protected functions to get rid of spurious error. The
410 transformation done by this procedure triggers legality errors
411 in the generated code in this case.
413 2019-08-14 Bob Duff <duff@adacore.com>
415 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
416 processing to the back end in all cases where the pragma's
417 condition is not known at compile time during the front end
418 (except in generics), as opposed to detecting 'Size attributes
419 and the like. This ensures that we take advantage of whatever
420 can be compile-time known after running the back end, as opposed
421 to having the front end guess what the back end can do. Remove
422 a little duplicated code at the call site.
423 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
424 Elists while in Validate_Compile_Time_Warning_Errors, because it
425 does analysis and name resolution, which sometimes involves
428 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
430 * einfo.ads (Is_Called): Document new usage on E_Package
432 * einfo.adb (Is_Called): Accept E_Package entities.
433 (Set_Is_Called): Likewise.
434 * exp_ch6.adb (Expand_Call_Helper): Move code dealing with
435 instances for back-end inlining to Add_Inlined_Body.
436 * inline.ads: Remove with clauses for Alloc and Table.
437 (Pending_Instantiations): Move to...
438 * inline.adb: Add with clauses for Alloc, Uintp, Table and
440 (Backend_Instances): New variable.
441 (Pending_Instantiations): ...here.
442 (Called_Pending_Instantiations): New table.
443 (Node_Table_Size): New constant.
444 (Node_Header_Num): New subtype.
445 (Node_Hash): New function.
446 (To_Pending_Instantiations): New hash table.
447 (Add_Inlined_Body): Bail out early for subprograms in the main
448 unit or subunit. Likewise if the Is_Called flag is set. If the
449 subprogram is an instance, invoke Add_Inlined_Instance. Call
450 Set_Is_Called earlier. If the subrogram is within an instance,
451 invoke Add_Inlined_Instance. Also deal with the case where the
452 call itself is within an instance.
453 (Add_Inlined_Instance): New procedure.
454 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
455 (Add_Pending_Instantiation): Move the defence against ludicruous
456 number of instantiations to here. When back-end inlining is
457 enabled, associate an instantiation with its index in table and
458 mark a few selected kinds of instantiations as always needed.
459 (Initialize): Set Backend_Instances to No_Elist.
460 (Instantiate_Body): New procedure doing the work extracted
462 (Instantiate_Bodies): ...here. When back-end inlining is
463 enabled, loop over Called_Pending_Instantiations instead of
464 Pending_Instantiations.
465 (Is_Nested): Minor tweak.
466 (List_Inlining_Info): Also list the contents of
468 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
469 is set and otherwise set it before returning true.
470 (Analyze_Package_Instantiation): Remove the defence against
471 ludicruous number of instantiations. Invoke
472 Remove_Dead_Instance instead of doing the removal manually if
473 there is a guaranteed ABE.
475 2019-08-14 Gary Dismukes <dismukes@adacore.com>
477 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
478 of an interface type, create an expression function (that
479 returns False) rather than declaring an abstract function.
480 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
481 False unconditionally at the start of the loop creating wrappers
482 for inherited operations.
484 2019-08-14 Bob Duff <duff@adacore.com>
486 * table.adb: Assert that the table is not locked when increasing
487 Last, even if it doesn't cause reallocation. In other words,
488 assert that on operations that MIGHT cause reallocation.
489 * table.ads: Fix comment accordingly.
491 2019-08-14 Arnaud Charlet <charlet@adacore.com>
493 * doc/gnat_ugn/gnat_and_program_execution.rst: Remove
494 documentation of gnatelim.
496 2019-08-14 Bob Duff <duff@adacore.com>
498 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
499 warning to the Sloc of the first pragma argument, rather than to
500 the pragma itself. This is to make pragmas processed after the
501 back end use the same Sloc as pragmas processed earlier, in the
502 front end. There's no reason for this discrepancy, and it
503 hinders further work on this ticket.
505 2019-08-14 Bob Duff <duff@adacore.com>
507 * sem.ads (Inside_A_Generic): Remove the ??? comment.
509 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
511 * inline.ads (Pending_Descriptor): Delete.
512 * inline.adb (Initialize): Do not initialize it.
513 * sem_ch12.adb (Delay_Descriptors): Delete.
514 (Analyze_Package_Instantiation): Call
515 Set_Delay_Subprogram_Descriptors instead of Delay_Descriptors
518 2019-08-14 Bob Duff <duff@adacore.com>
520 * exp_aggr.adb (Init_Hidden_Discriminants): Avoid processing the
521 wrong discriminant, which could be of the wrong type.
523 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
525 * sem_ch12.adb (Analyze_Instance_And_Renamings): Do not reset
526 the Is_Generic_Instance flag previously set on the package
527 generated for the instantiation of a generic subprogram.
529 2019-08-14 Ed Schonberg <schonberg@adacore.com>
531 * exp_ch4.adb (Expand_N_Quantified_Expression): Freeze
532 explicitly the type of the loop parameter.
534 2019-08-14 Javier Miranda <miranda@adacore.com>
536 * sem_util.adb (New_Copy_Tree.Copy_Node_With_Replacement):
537 Update the Chars attribute of identifiers.
539 2019-08-14 Yannick Moy <moy@adacore.com>
541 * sem_spark.adb, sem_spark.ads (Is_Legal): New function exposed
542 for use in GNATprove, to test legality rules not related to
544 (Check_Declaration_Legality): Extract the part of
545 Check_Declaration that checks rules not related to permissions.
546 (Check_Declaration): Call the new Check_Declaration_Legality.

1202 'Valid as a replacement for a range check on a discrete type
1203 when the bounds of the range are given by type conversions,
1204 because in such a case there are distinct types involved and the
1205 subbested attribute replacement would be misplaced.
1207 2019-07-22 Yannick Moy <moy@adacore.com>
1209 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,
1210 Is_Subpath_Expression): Add parameter Is_Traversal to adapt

1271 libgnat/s-valwch.ads: Change categorization of packages that
1272 implement attribute 'Value from Pure to Preelaborate, to prevent
1273 undesirable optimizations when the evaluation of the attribute
1274 raises Constraint_Error, but subsequent use of the result of
1275 this evsaluation is removed by a subsequent optimization.

1293 Index_Table with range Natural'First .. Names'Length since in
1294 the worst case all the literals of the enumeration type would be
1295 single letter literals and the Table built by the frontend would
1296 have as many components as the length of the names string. As a
1297 result of this enhancement, the internal tables declared using
1298 Index_Table have a length closer to the real needs, thus
1299 avoiding the declaration of large arrays on 32-bit CCG targets.
