3 * sem_ch13.adb (Is_Null_Array): New function, used to detect the
4 null array case; used to warn about uncheckedly converting to a
5 zero-sized array. It is unfortunate that we can't just check
6 the size, and warn on all cases of converting from a
7 nonzero-sized type to a zero-sized one. That's because "0" means
8 two different things: "size is zero" and "size is unknown".
9 Until we fix that design flaw, we need this more targeted fix.
11 2019-08-20 Bob Duff <duff@adacore.com>
13 * libgnat/a-cborma.adb, libgnat/a-cborse.adb (Clear): Repeatedly
14 call Delete. This avoids clearing the free list, which
15 substantially speeds up future Delete operations.
17 2019-08-20 Bob Duff <duff@adacore.com>
19 * sem_ch13.adb (Component_Order_Check): New procedure to check
20 for out-of-order clauses.
21 * warnsw.ads, warnsw.adb: New -gnatw_r switch.
22 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
24 * gnat_ugn.texi: Regenerate.
26 2019-08-20 Bob Duff <duff@adacore.com>
28 * sem_ch13.adb (Object_Size): Give an error for zero. It really
29 rubs me the wrong way that we don't honor "for T'Object_Size use
30 0;", but it's not important enough to fix. In any case, if we're
31 not going to obey the clause, we should give an error.
33 2019-08-20 Bob Duff <duff@adacore.com>
35 * errout.adb (Error_Msg_Internal): Set Warn_Err in case of
37 * erroutc.adb (Output_Msg_Text): Do Warnings_Treated_As_Errors
38 processing and [warning-as-error] modification for style
39 messages. Clean up code, simplify, remove unnecessary block
40 statement, add renaming of table entry.
41 * erroutc.ads (Warning_Treated_As_Error): Fix comment: no such
42 thing as Set_Warning_As_Error.
43 * opt.ads: Clean up comments and move related declarations near
45 * par-prag.adb: Process Warning_As_Error. This is necessary
46 because many style warning happen during parsing.
47 * sem_prag.adb: Use new Acquire_Warning_Match_String.
48 * sem_util.ads, sem_util.adb (Acquire_Warning_Match_String): New
49 function shared by par-prag.adb and sem_prag.adb. Replaces the
50 procedure in sem_prag.adb. Avoid use of global variables.
51 * stringt.ads, stringt.adb (To_String): New function to convert
53 * doc/gnat_rm/implementation_defined_pragmas.rst: Document the
55 * gnat_rm.texi: Regenerate.
57 2019-08-20 Eric Botcazou <ebotcazou@adacore.com>

60 Add pragma Inline for Is_Loaded and alphabetize the list.
61 (Unit_Name_Table_Size): New constant.
62 (Unit_Name_Header_Num): New subtype.
63 (Unit_Name_Hash): New function declaration.
64 (Unit_Names): New simple hash table.
65 (Init_Unit_Name): New procedure declaration.
66 * lib.adb (Set_Unit_Name): Unregister the old name in the table,
67 if any, and then register the new name.
68 (Init_Unit_Name): New procedure.
69 (Is_Loaded): Reimplement using a lookup in the names table.
70 (Remove_Unit): Unregister the name.
71 (Unit_Name_Hash): New function.
72 * lib-load.adb (Create_Dummy_Package_Unit): Call Init_Unit_Name.
73 (Load_Unit): Use a lookup in the names table to find out whether
74 the unit has already been loaded. Call Init_Unit_Name and then
75 Remove_Unit if the loading has failed.
76 (Make_Child_Decl_Unit): Call Init_Unit_Name.
77 (Make_Instance_Unit): Likewise.
78 * lib-writ.adb (Ensure_System_Dependency): Likewise.
80 2019-08-20 Bob Duff <duff@adacore.com>
82 * sem_ch13.adb (Record_Hole_Check): Initialize After_Last.
84 2019-08-20 Piotr Trojanek <trojanek@adacore.com>
86 * impunit.adb (Get_Kind_Of_Unit): Revert change for adapting
87 this routine for gnatprove.
89 2019-08-20 Arnaud Charlet <charlet@adacore.com>
91 * doc/gnat_rm/implementation_defined_pragmas.rst: Document
92 requirements for Pragma Lock_Free.
93 * gnat_rm.texi: Regenerate.
95 2019-08-20 Philippe Gil <gil@adacore.com>
97 * bindgen.adb (Gen_Main): Set gnat_argc/gnat_argv to argc/argv
98 only when still uninitialized.
100 2019-08-20 Bob Duff <duff@adacore.com>
102 * libgnat/g-comlin.ads (Exit_From_Command_Line): Fix
103 documentation for GNAT.Command_Line.
105 2019-08-20 Pierre-Marie de Rodat <derodat@adacore.com>
108 * gcc-interface/lang.opt (-fdump-scos): Add missing dot at the
109 end of the documentation.
111 2019-08-20 Richard Sandiford <richard.sandiford@arm.com>
113 * gcc-interface/misc.c (default_pass_by_ref): Update call to

122 2019-08-19 Gary Dismukes <dismukes@adacore.com>
124 * einfo.ads (E_Function, E_Procedure): Update comments to
125 reflect that Renamed_Entity is also used for nongeneric

136 on formal parameters of dispatching operations.
138 2019-08-19 Ed Schonberg <schonberg@adacore.com>

141 freezes when expander is active, unless the call appears within
142 the body of another expression function,
144 2019-08-19 Dmitriy Anisimkov <anisimko@adacore.com>
146 * libgnat/s-os_lib.ads, libgnat/s-os_lib.adb (To_Ada, To_C): New
149 2019-08-19 Bob Duff <duff@adacore.com>
151 * exp_attr.adb (Attribute_Valid): Correct the handling of
152 private types where the full type is modular. System.Address is
153 an example. Otherwise, we convert uncheckedly to a signed type,
154 so we get an incorrect range 0 .. -1, for which all values will
155 fail. The 'Valid attribute is illegal for such types, but we
156 generate such illegal attribute_references for 'Valid_Scalars,
157 and we generate 'Valid_Scalars when the -gnateV switch is used.
158 Rename Btyp --> PBtyp to avoid hiding the outer Btyp, which was
160 * libgnat/a-except.adb: Set the Exception_Raised component.
161 Otherwise, we have incorrect reads of invalid data.
163 2019-08-19 Pierre-Marie de Rodat <derodat@adacore.com>
165 * libgnat/a-cgaaso.ads, libgnat/a-cgarso.ads,

174 ada_target_properties.
176 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
178 * inline.adb (Add_Inlined_Body): Do not special-case instances
179 that are compilation units.
180 (Add_Pending_Instantiation): Likewise.
181 (Instantiate_Body): Skip instantiations that are compilation
182 units and have already been performed.
183 * sem_ch12.adb (Needs_Body_Instantiated): Do not special-case
184 instances that are compilation units.
185 (Load_Parent_Of_Generic): Be prepared for parent that is a
186 compilation unit but whose instantiation node has not been

192 Called_Pending_Instantiations.
194 2019-08-19 Ed Schonberg <schonberg@adacore.com>
196 * sem_ch6.adb (Check_Synchronized_Overriding): Complete
197 predicate that applies legality check in 9.4 (11.9/2): if an
198 inherited subprogram is implemented by a protected procedure or
199 entry, its first paarameter must be out, in_out or
202 2019-08-19 Javier Miranda <miranda@adacore.com>
205 * exp_atag.ads, exp_atag.adb (Build_Inherit_Predefined_Prims):
206 Adding formal to specify how many predefined primitives are
207 inherited from the parent type.
208 * exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
209 (Make_Secondary_DT): Compute the number of predefined primitives
210 of all tagged types (including tagged types not defined at
211 library level). Previously we unconditionally relied on the
212 Max_Predef_Prims constant value when building the dispatch
213 tables of tagged types not defined at library level (thus
214 consuming more memory for their dispatch tables than required).
215 (Make_DT): Compute the number of predefined primitives that must
216 be inherited from their parent type when building the dispatch
217 tables of tagged types not defined at library level. Previously
218 we unconditionally relied on the Max_Predef_Prims constant value
219 when building the dispatch tables of tagged types not defined at
220 library level (thus copying more data than required from the
223 2019-08-19 Bob Duff <duff@adacore.com>
225 * sem_ch13.adb (Record_Hole_Check): Procedure to check for holes
226 that incudes processing type extensions. A type extension is
227 processed by first calling Record_Hole_Check recursively on the
228 parent type to compute the bit number after the last component
231 2019-08-19 Gary Dismukes <dismukes@adacore.com>
233 * checks.adb (Length_Mismatch_Info_Message): New function in
234 Selected_Length_Checks to return a message indicating the
235 element counts for the mismatched lengths for a failed
236 compile-time length check.
237 (Plural_Or_Singular_Ending): Support function in
238 Length_Mismatch_Info_Message to return either "" or "s", for
239 concatenating to the end of words.
240 (Selected_Length_Checks): Pass the result of
241 Length_Mismatch_Info_Message as an extra warning message to
242 Compile_Time_Constraint_Error to indicate the mismatched lengths
243 for a failed compile-time length check.
244 * sem_util.ads (Compile_Time_Constraint_Error): Add an optional
245 message formal (Extra_Msg), defaulted to the empty string.
246 * sem_util.adb (Compile_Time_Constraint_Error): Output an extra
247 message following the main warning message (when Extra_Msg is
248 not the empty string).
250 2019-08-19 Patrick Bernardi <bernardi@adacore.com>
252 * socket.c: Removed the redefinition of getaddrinfo, getnameinfo
253 and freeaddrinfo to internal VxWorks kernel calls because they
254 are, well, internal kernel calls and cannot be called from RTPs.
255 VxWorks provides the necessary components to call these routines
258 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
260 * exp_dist.adb (Is_Generic_Actual_Subtype): New predicate.
261 (Build_From_Any_Call, Build_To_Any_Call, Build_TypeCode_Call):
262 Use it instead of Is_Generic_Actual_Type flag to detect subtypes
263 representing generic actual types.
265 2019-08-19 Ed Schonberg <schonberg@adacore.com>
267 * sem_warn.adb (Check_References, Generic_Body_Formal): When a
268 formal parameter of a generic subprogram is not referenced in
269 the body, place the corresponding warning on the corresponding
270 entity in the specification of the generic body, as is done for
271 non-generic subprograms.
273 2019-08-19 Bob Duff <duff@adacore.com>
275 * errout.ads (Size_Too_Small_Message): New constant.

297 * sem_spark.ads, sem_spark.adb (Is_Pledge_Function): New
298 parameter of the generic. Function used to decide whether a
299 function is a pledge function.
300 (Check_Not_Borrowed): Disable check inside the second parameter
301 of a pledge function for the path borrowed by the first

345 * gcc-interface/lang.opt (fdump-scos): Define.
346 * gcc-interface/misc.c (gnat_handle_option): Handle
349 2019-08-14 Joffrey Huguet <huguet@adacore.com>
351 * libgnat/a-cofuba.ads: Add a Length attribute to type
352 Container. Add a type Array_Base which replaces the previous
353 Elements attribute of Container.
354 (Content_Init): New subprogram. It is used to initialize the
355 Base attribute of Container.
356 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
357 resize the underlying array of a container if necessary.
358 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,
359 Union): Update to match changes in type declarations.
360 (Add): Modify body to damp the time and space cost in a specific
362 (Content_Init): New subprogram. It is used to initialize the
363 Base attribute of Container.
364 (Remove): Modify body to damp the time and space cost in a

370 and do not give an error.

377 * inline.adb (Add_Pending_Instantiation): Fix off-by-one error
378 in the comparison against the maximum number of instantiations.
380 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
382 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
383 in the comparison against the maximum number of instantiations.
385 2019-08-14 Ed Schonberg <schonberg@adacore.com>
387 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
388 involves a Ghost aspect it may have been replaced by a null
389 statement; use the original node to find next Rep_Item.
390 * repinfo.adb (List_Entities): Do not list an Ignored
391 Ghost_Entity, for which information may have been deleted.
393 2019-08-14 Bob Duff <duff@adacore.com>
395 * sem_prag.ads, sem_prag.adb
396 (Process_Compile_Time_Warning_Or_Error): In parameterless
397 version, improve detection of whether we are in a generic unit
398 to cover the case of an instance within a generic unit.
399 (Process_Compile_Time_Warning_Or_Error): Rename the
400 two-parameter version to be
401 Validate_Compile_Time_Warning_Or_Error, and do not export it.
402 Issue a warning if the condition is not known at compile time.
403 The key point is that the warning must be given only for pragmas
404 deferred to the back end, because the back end discovers
405 additional values that are known at compile time. Previous
406 changes in this ticket have enabled this by deferring to the
407 back end without checking for special cases such as 'Size.
408 (Validate_Compile_Time_Warning_Or_Error): Rename to be
409 Defer_Compile_Time_Warning_Error_To_BE.
410 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):
411 Add new switches -gnatw_c and -gnatw_C to control the above
413 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
414 Document new switches.
415 * gnat_ugn.texi: Regenerate.
417 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
419 * sem_ch12.adb (Might_Inline_Subp): Rework comment and restrict
420 the shortcut based on Is_Inlined to the back-end inlining case.
422 2019-08-14 Bob Duff <duff@adacore.com>
424 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
425 protected functions to get rid of spurious error. The
426 transformation done by this procedure triggers legality errors
427 in the generated code in this case.
429 2019-08-14 Bob Duff <duff@adacore.com>
431 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
432 processing to the back end in all cases where the pragma's
433 condition is not known at compile time during the front end
434 (except in generics), as opposed to detecting 'Size attributes
435 and the like. This ensures that we take advantage of whatever
436 can be compile-time known after running the back end, as opposed
437 to having the front end guess what the back end can do. Remove
438 a little duplicated code at the call site.
439 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
440 Elists while in Validate_Compile_Time_Warning_Errors, because it
441 does analysis and name resolution, which sometimes involves
444 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
446 * einfo.ads (Is_Called): Document new usage on E_Package
448 * einfo.adb (Is_Called): Accept E_Package entities.
449 (Set_Is_Called): Likewise.
450 * exp_ch6.adb (Expand_Call_Helper): Move code dealing with
451 instances for back-end inlining to Add_Inlined_Body.
452 * inline.ads: Remove with clauses for Alloc and Table.
453 (Pending_Instantiations): Move to...
454 * inline.adb: Add with clauses for Alloc, Uintp, Table and
456 (Backend_Instances): New variable.
457 (Pending_Instantiations): ...here.
458 (Called_Pending_Instantiations): New table.
459 (Node_Table_Size): New constant.
460 (Node_Header_Num): New subtype.
461 (Node_Hash): New function.
462 (To_Pending_Instantiations): New hash table.
463 (Add_Inlined_Body): Bail out early for subprograms in the main
464 unit or subunit. Likewise if the Is_Called flag is set. If the
465 subprogram is an instance, invoke Add_Inlined_Instance. Call
466 Set_Is_Called earlier. If the subrogram is within an instance,
467 invoke Add_Inlined_Instance. Also deal with the case where the
468 call itself is within an instance.
469 (Add_Inlined_Instance): New procedure.
470 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
471 (Add_Pending_Instantiation): Move the defence against ludicruous
472 number of instantiations to here. When back-end inlining is
473 enabled, associate an instantiation with its index in table and
474 mark a few selected kinds of instantiations as always needed.
475 (Initialize): Set Backend_Instances to No_Elist.
476 (Instantiate_Body): New procedure doing the work extracted
478 (Instantiate_Bodies): ...here. When back-end inlining is
479 enabled, loop over Called_Pending_Instantiations instead of
480 Pending_Instantiations.
481 (Is_Nested): Minor tweak.
482 (List_Inlining_Info): Also list the contents of
484 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
485 is set and otherwise set it before returning true.
486 (Analyze_Package_Instantiation): Remove the defence against
487 ludicruous number of instantiations. Invoke
488 Remove_Dead_Instance instead of doing the removal manually if
489 there is a guaranteed ABE.
491 2019-08-14 Gary Dismukes <dismukes@adacore.com>
493 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
494 of an interface type, create an expression function (that
495 returns False) rather than declaring an abstract function.
496 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
497 False unconditionally at the start of the loop creating wrappers
498 for inherited operations.
500 2019-08-14 Bob Duff <duff@adacore.com>
502 * table.adb: Assert that the table is not locked when increasing
503 Last, even if it doesn't cause reallocation. In other words,
504 assert that on operations that MIGHT cause reallocation.
505 * table.ads: Fix comment accordingly.
507 2019-08-14 Arnaud Charlet <charlet@adacore.com>
509 * doc/gnat_ugn/gnat_and_program_execution.rst: Remove
510 documentation of gnatelim.
512 2019-08-14 Bob Duff <duff@adacore.com>
514 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
515 warning to the Sloc of the first pragma argument, rather than to
516 the pragma itself. This is to make pragmas processed after the
517 back end use the same Sloc as pragmas processed earlier, in the
518 front end. There's no reason for this discrepancy, and it
519 hinders further work on this ticket.
521 2019-08-14 Bob Duff <duff@adacore.com>
523 * sem.ads (Inside_A_Generic): Remove the ??? comment.
525 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
527 * inline.ads (Pending_Descriptor): Delete.
528 * inline.adb (Initialize): Do not initialize it.

531 Set_Delay_Subprogram_Descriptors instead of Delay_Descriptors
534 2019-08-14 Bob Duff <duff@adacore.com>
536 * exp_aggr.adb (Init_Hidden_Discriminants): Avoid processing the
537 wrong discriminant, which could be of the wrong type.
539 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
541 * sem_ch12.adb (Analyze_Instance_And_Renamings): Do not reset

1218 'Valid as a replacement for a range check on a discrete type
1219 when the bounds of the range are given by type conversions,
1220 because in such a case there are distinct types involved and the
1221 subbested attribute replacement would be misplaced.
1223 2019-07-22 Yannick Moy <moy@adacore.com>
1225 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,
1226 Is_Subpath_Expression): Add parameter Is_Traversal to adapt

1263 * sem_res.adb (Resolve_Actuals): Replace code that displaces the

1287 libgnat/s-valwch.ads: Change categorization of packages that
1288 implement attribute 'Value from Pure to Preelaborate, to prevent
1289 undesirable optimizations when the evaluation of the attribute
1290 raises Constraint_Error, but subsequent use of the result of
1291 this evsaluation is removed by a subsequent optimization.

1309 Index_Table with range Natural'First .. Names'Length since in
1310 the worst case all the literals of the enumeration type would be
1311 single letter literals and the Table built by the frontend would
1312 have as many components as the length of the names string. As a
1313 result of this enhancement, the internal tables declared using
1314 Index_Table have a length closer to the real needs, thus
1315 avoiding the declaration of large arrays on 32-bit CCG targets.
