1 2019-08-20 Bob Duff <duff@adacore.com>
3 * sem_eval.adb (Expr_Value): Implement the case of an unchecked
4 conversion of a static expression.
6 2019-08-20 Bob Duff <duff@adacore.com>
8 * sem_ch13.adb (Is_Null_Array): New function, used to detect the
9 null array case; used to warn about uncheckedly converting to a
10 zero-sized array. It is unfortunate that we can't just check
11 the size, and warn on all cases of converting from a
12 nonzero-sized type to a zero-sized one. That's because "0" means
13 two different things: "size is zero" and "size is unknown".
14 Until we fix that design flaw, we need this more targeted fix.
16 2019-08-20 Bob Duff <duff@adacore.com>
18 * libgnat/a-cborma.adb, libgnat/a-cborse.adb (Clear): Repeatedly
19 call Delete. This avoids clearing the free list, which
20 substantially speeds up future Delete operations.
22 2019-08-20 Bob Duff <duff@adacore.com>
24 * sem_ch13.adb (Component_Order_Check): New procedure to check
25 for out-of-order clauses.
26 * warnsw.ads, warnsw.adb: New -gnatw_r switch.
27 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
29 * gnat_ugn.texi: Regenerate.
31 2019-08-20 Bob Duff <duff@adacore.com>
33 * sem_ch13.adb (Object_Size): Give an error for zero. It really
34 rubs me the wrong way that we don't honor "for T'Object_Size use
35 0;", but it's not important enough to fix. In any case, if we're
36 not going to obey the clause, we should give an error.
38 2019-08-20 Bob Duff <duff@adacore.com>
40 * errout.adb (Error_Msg_Internal): Set Warn_Err in case of
42 * erroutc.adb (Output_Msg_Text): Do Warnings_Treated_As_Errors
43 processing and [warning-as-error] modification for style
44 messages. Clean up code, simplify, remove unnecessary block
45 statement, add renaming of table entry.
46 * erroutc.ads (Warning_Treated_As_Error): Fix comment: no such
47 thing as Set_Warning_As_Error.
48 * opt.ads: Clean up comments and move related declarations near
50 * par-prag.adb: Process Warning_As_Error. This is necessary
51 because many style warning happen during parsing.
52 * sem_prag.adb: Use new Acquire_Warning_Match_String.
53 * sem_util.ads, sem_util.adb (Acquire_Warning_Match_String): New
54 function shared by par-prag.adb and sem_prag.adb. Replaces the
55 procedure in sem_prag.adb. Avoid use of global variables.
56 * stringt.ads, stringt.adb (To_String): New function to convert
58 * doc/gnat_rm/implementation_defined_pragmas.rst: Document the
60 * gnat_rm.texi: Regenerate.
62 2019-08-20 Eric Botcazou <ebotcazou@adacore.com>
64 * lib.ads: Add with clause for GNAT.HTable.
65 Add pragma Inline for Is_Loaded and alphabetize the list.
66 (Unit_Name_Table_Size): New constant.
67 (Unit_Name_Header_Num): New subtype.
68 (Unit_Name_Hash): New function declaration.
69 (Unit_Names): New simple hash table.
70 (Init_Unit_Name): New procedure declaration.
71 * lib.adb (Set_Unit_Name): Unregister the old name in the table,
72 if any, and then register the new name.
73 (Init_Unit_Name): New procedure.
74 (Is_Loaded): Reimplement using a lookup in the names table.
75 (Remove_Unit): Unregister the name.
76 (Unit_Name_Hash): New function.
77 * lib-load.adb (Create_Dummy_Package_Unit): Call Init_Unit_Name.
78 (Load_Unit): Use a lookup in the names table to find out whether
79 the unit has already been loaded. Call Init_Unit_Name and then
80 Remove_Unit if the loading has failed.
81 (Make_Child_Decl_Unit): Call Init_Unit_Name.
82 (Make_Instance_Unit): Likewise.
83 * lib-writ.adb (Ensure_System_Dependency): Likewise.
85 2019-08-20 Bob Duff <duff@adacore.com>
87 * sem_ch13.adb (Record_Hole_Check): Initialize After_Last.
89 2019-08-20 Piotr Trojanek <trojanek@adacore.com>
91 * impunit.adb (Get_Kind_Of_Unit): Revert change for adapting
92 this routine for gnatprove.
94 2019-08-20 Arnaud Charlet <charlet@adacore.com>
96 * doc/gnat_rm/implementation_defined_pragmas.rst: Document
97 requirements for Pragma Lock_Free.
98 * gnat_rm.texi: Regenerate.
100 2019-08-20 Philippe Gil <gil@adacore.com>
102 * bindgen.adb (Gen_Main): Set gnat_argc/gnat_argv to argc/argv
103 only when still uninitialized.
105 2019-08-20 Bob Duff <duff@adacore.com>
107 * libgnat/g-comlin.ads (Exit_From_Command_Line): Fix
108 documentation for GNAT.Command_Line.
110 2019-08-20 Pierre-Marie de Rodat <derodat@adacore.com>
113 * gcc-interface/lang.opt (-fdump-scos): Add missing dot at the
114 end of the documentation.
116 2019-08-20 Richard Sandiford <richard.sandiford@arm.com>
118 * gcc-interface/misc.c (default_pass_by_ref): Update call to
121 2019-08-19 Bob Duff <duff@adacore.com>
123 * doc/gnat_rm/implementation_advice.rst: Fix documentation for
124 stream oriented attributes.
125 * gnat_rm.texi: Regenerate.
127 2019-08-19 Gary Dismukes <dismukes@adacore.com>
129 * einfo.ads (E_Function, E_Procedure): Update comments to
130 reflect that Renamed_Entity is also used for nongeneric
133 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
135 * sem_prag.adb (Is_Before_First_Decl): Deal with rewritten
138 2019-08-19 Bob Duff <duff@adacore.com>
140 * sem_warn.adb (Warn_On_Unreferenced_Entity): Suppress warning
141 on formal parameters of dispatching operations.
143 2019-08-19 Ed Schonberg <schonberg@adacore.com>
145 * sem_res.adb (Resolve_Call): A call to an expression function
146 freezes when expander is active, unless the call appears within
147 the body of another expression function,
149 2019-08-19 Dmitriy Anisimkov <anisimko@adacore.com>
151 * libgnat/s-os_lib.ads, libgnat/s-os_lib.adb (To_Ada, To_C): New
154 2019-08-19 Bob Duff <duff@adacore.com>
156 * exp_attr.adb (Attribute_Valid): Correct the handling of
157 private types where the full type is modular. System.Address is
158 an example. Otherwise, we convert uncheckedly to a signed type,
159 so we get an incorrect range 0 .. -1, for which all values will
160 fail. The 'Valid attribute is illegal for such types, but we
161 generate such illegal attribute_references for 'Valid_Scalars,
162 and we generate 'Valid_Scalars when the -gnateV switch is used.
163 Rename Btyp --> PBtyp to avoid hiding the outer Btyp, which was
165 * libgnat/a-except.adb: Set the Exception_Raised component.
166 Otherwise, we have incorrect reads of invalid data.
168 2019-08-19 Pierre-Marie de Rodat <derodat@adacore.com>
170 * libgnat/a-cgaaso.ads, libgnat/a-cgarso.ads,

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

197 Called_Pending_Instantiations.
199 2019-08-19 Ed Schonberg <schonberg@adacore.com>
201 * sem_ch6.adb (Check_Synchronized_Overriding): Complete
202 predicate that applies legality check in 9.4 (11.9/2): if an
203 inherited subprogram is implemented by a protected procedure or
204 entry, its first paarameter must be out, in_out or
207 2019-08-19 Javier Miranda <miranda@adacore.com>
210 * exp_atag.ads, exp_atag.adb (Build_Inherit_Predefined_Prims):
211 Adding formal to specify how many predefined primitives are
212 inherited from the parent type.
213 * exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
214 (Make_Secondary_DT): Compute the number of predefined primitives
215 of all tagged types (including tagged types not defined at
216 library level). Previously we unconditionally relied on the
217 Max_Predef_Prims constant value when building the dispatch
218 tables of tagged types not defined at library level (thus
219 consuming more memory for their dispatch tables than required).
220 (Make_DT): Compute the number of predefined primitives that must
221 be inherited from their parent type when building the dispatch
222 tables of tagged types not defined at library level. Previously
223 we unconditionally relied on the Max_Predef_Prims constant value
224 when building the dispatch tables of tagged types not defined at
225 library level (thus copying more data than required from the
228 2019-08-19 Bob Duff <duff@adacore.com>
230 * sem_ch13.adb (Record_Hole_Check): Procedure to check for holes
231 that incudes processing type extensions. A type extension is
232 processed by first calling Record_Hole_Check recursively on the
233 parent type to compute the bit number after the last component
236 2019-08-19 Gary Dismukes <dismukes@adacore.com>
238 * checks.adb (Length_Mismatch_Info_Message): New function in
239 Selected_Length_Checks to return a message indicating the
240 element counts for the mismatched lengths for a failed
241 compile-time length check.
242 (Plural_Or_Singular_Ending): Support function in
243 Length_Mismatch_Info_Message to return either "" or "s", for
244 concatenating to the end of words.
245 (Selected_Length_Checks): Pass the result of
246 Length_Mismatch_Info_Message as an extra warning message to
247 Compile_Time_Constraint_Error to indicate the mismatched lengths
248 for a failed compile-time length check.
249 * sem_util.ads (Compile_Time_Constraint_Error): Add an optional
250 message formal (Extra_Msg), defaulted to the empty string.
251 * sem_util.adb (Compile_Time_Constraint_Error): Output an extra
252 message following the main warning message (when Extra_Msg is
253 not the empty string).
255 2019-08-19 Patrick Bernardi <bernardi@adacore.com>
257 * socket.c: Removed the redefinition of getaddrinfo, getnameinfo
258 and freeaddrinfo to internal VxWorks kernel calls because they
259 are, well, internal kernel calls and cannot be called from RTPs.
260 VxWorks provides the necessary components to call these routines
263 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
265 * exp_dist.adb (Is_Generic_Actual_Subtype): New predicate.
266 (Build_From_Any_Call, Build_To_Any_Call, Build_TypeCode_Call):
267 Use it instead of Is_Generic_Actual_Type flag to detect subtypes
268 representing generic actual types.
270 2019-08-19 Ed Schonberg <schonberg@adacore.com>
272 * sem_warn.adb (Check_References, Generic_Body_Formal): When a
273 formal parameter of a generic subprogram is not referenced in
274 the body, place the corresponding warning on the corresponding
275 entity in the specification of the generic body, as is done for
276 non-generic subprograms.
278 2019-08-19 Bob Duff <duff@adacore.com>
280 * errout.ads (Size_Too_Small_Message): New constant.
281 * errout.adb, freeze.adb, sem_ch13.adb: Use it.
283 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
285 * exp_dist.adb (Build_Package_Stubs): Do not specifically visit
286 the declarations of an N_Subprogram_Instantiation node.

298 local variable if needed.
300 2019-08-19 Claire Dross <dross@adacore.com>
302 * sem_spark.ads, sem_spark.adb (Is_Pledge_Function): New
303 parameter of the generic. Function used to decide whether a
304 function is a pledge function.
305 (Check_Not_Borrowed): Disable check inside the second parameter
306 of a pledge function for the path borrowed by the first
307 parameter. Also disable checks for entities inside a Global

323 2019-08-19 Ed Schonberg <schonberg@adacore.com>
325 * sem_ch3.adb (Derived_Enumeration_Type): Do no freeze anonymous
326 base type if the bounds in the derived type declaration are
327 literals of the type.

340 a pending instantiation for the body of the package.
342 2019-08-19 Olivier Hainque <hainque@adacore.com>
344 * gcc-interface/trans.c (Acc_Loop_to_gnu): Return the openacc
345 BIND_EXPR node we have constructed on purpose. Remove unused
348 2019-08-19 Pierre-Marie de Rodat <derodat@adacore.com>
350 * gcc-interface/lang.opt (fdump-scos): Define.
351 * gcc-interface/misc.c (gnat_handle_option): Handle
354 2019-08-14 Joffrey Huguet <huguet@adacore.com>
356 * libgnat/a-cofuba.ads: Add a Length attribute to type
357 Container. Add a type Array_Base which replaces the previous
358 Elements attribute of Container.
359 (Content_Init): New subprogram. It is used to initialize the
360 Base attribute of Container.
361 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
362 resize the underlying array of a container if necessary.
363 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,
364 Union): Update to match changes in type declarations.
365 (Add): Modify body to damp the time and space cost in a specific
367 (Content_Init): New subprogram. It is used to initialize the
368 Base attribute of Container.
369 (Remove): Modify body to damp the time and space cost in a
372 2019-08-14 Bob Duff <duff@adacore.com>
374 * sem_ch13.adb (Get_Alignment_Value): Return 1 for Alignment 0,
375 and do not give an error.
376 * doc/gnat_rm/representation_clauses_and_pragmas.rst: Update the
377 corresponding documentation.

380 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
382 * inline.adb (Add_Pending_Instantiation): Fix off-by-one error
383 in the comparison against the maximum number of instantiations.
385 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
387 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
388 in the comparison against the maximum number of instantiations.
390 2019-08-14 Ed Schonberg <schonberg@adacore.com>
392 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
393 involves a Ghost aspect it may have been replaced by a null
394 statement; use the original node to find next Rep_Item.
395 * repinfo.adb (List_Entities): Do not list an Ignored
396 Ghost_Entity, for which information may have been deleted.
398 2019-08-14 Bob Duff <duff@adacore.com>
400 * sem_prag.ads, sem_prag.adb
401 (Process_Compile_Time_Warning_Or_Error): In parameterless
402 version, improve detection of whether we are in a generic unit
403 to cover the case of an instance within a generic unit.
404 (Process_Compile_Time_Warning_Or_Error): Rename the
405 two-parameter version to be
406 Validate_Compile_Time_Warning_Or_Error, and do not export it.
407 Issue a warning if the condition is not known at compile time.
408 The key point is that the warning must be given only for pragmas
409 deferred to the back end, because the back end discovers
410 additional values that are known at compile time. Previous
411 changes in this ticket have enabled this by deferring to the
412 back end without checking for special cases such as 'Size.
413 (Validate_Compile_Time_Warning_Or_Error): Rename to be
414 Defer_Compile_Time_Warning_Error_To_BE.
415 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):
416 Add new switches -gnatw_c and -gnatw_C to control the above
418 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
419 Document new switches.

422 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
424 * sem_ch12.adb (Might_Inline_Subp): Rework comment and restrict
425 the shortcut based on Is_Inlined to the back-end inlining case.
427 2019-08-14 Bob Duff <duff@adacore.com>
429 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
430 protected functions to get rid of spurious error. The
431 transformation done by this procedure triggers legality errors
432 in the generated code in this case.
434 2019-08-14 Bob Duff <duff@adacore.com>
436 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
437 processing to the back end in all cases where the pragma's
438 condition is not known at compile time during the front end
439 (except in generics), as opposed to detecting 'Size attributes
440 and the like. This ensures that we take advantage of whatever
441 can be compile-time known after running the back end, as opposed
442 to having the front end guess what the back end can do. Remove
443 a little duplicated code at the call site.
444 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
445 Elists while in Validate_Compile_Time_Warning_Errors, because it
446 does analysis and name resolution, which sometimes involves
449 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
451 * einfo.ads (Is_Called): Document new usage on E_Package
453 * einfo.adb (Is_Called): Accept E_Package entities.
454 (Set_Is_Called): Likewise.
455 * exp_ch6.adb (Expand_Call_Helper): Move code dealing with
456 instances for back-end inlining to Add_Inlined_Body.
457 * inline.ads: Remove with clauses for Alloc and Table.
458 (Pending_Instantiations): Move to...
459 * inline.adb: Add with clauses for Alloc, Uintp, Table and
461 (Backend_Instances): New variable.
462 (Pending_Instantiations): ...here.
463 (Called_Pending_Instantiations): New table.
464 (Node_Table_Size): New constant.
465 (Node_Header_Num): New subtype.
466 (Node_Hash): New function.
467 (To_Pending_Instantiations): New hash table.
468 (Add_Inlined_Body): Bail out early for subprograms in the main
469 unit or subunit. Likewise if the Is_Called flag is set. If the
470 subprogram is an instance, invoke Add_Inlined_Instance. Call
471 Set_Is_Called earlier. If the subrogram is within an instance,
472 invoke Add_Inlined_Instance. Also deal with the case where the
473 call itself is within an instance.
474 (Add_Inlined_Instance): New procedure.
475 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
476 (Add_Pending_Instantiation): Move the defence against ludicruous
477 number of instantiations to here. When back-end inlining is
478 enabled, associate an instantiation with its index in table and
479 mark a few selected kinds of instantiations as always needed.
480 (Initialize): Set Backend_Instances to No_Elist.
481 (Instantiate_Body): New procedure doing the work extracted
483 (Instantiate_Bodies): ...here. When back-end inlining is
484 enabled, loop over Called_Pending_Instantiations instead of
485 Pending_Instantiations.
486 (Is_Nested): Minor tweak.
487 (List_Inlining_Info): Also list the contents of
489 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
490 is set and otherwise set it before returning true.
491 (Analyze_Package_Instantiation): Remove the defence against
492 ludicruous number of instantiations. Invoke
493 Remove_Dead_Instance instead of doing the removal manually if
494 there is a guaranteed ABE.
496 2019-08-14 Gary Dismukes <dismukes@adacore.com>
498 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
499 of an interface type, create an expression function (that
500 returns False) rather than declaring an abstract function.
501 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
502 False unconditionally at the start of the loop creating wrappers
503 for inherited operations.
505 2019-08-14 Bob Duff <duff@adacore.com>
507 * table.adb: Assert that the table is not locked when increasing
508 Last, even if it doesn't cause reallocation. In other words,
509 assert that on operations that MIGHT cause reallocation.
510 * table.ads: Fix comment accordingly.
512 2019-08-14 Arnaud Charlet <charlet@adacore.com>
514 * doc/gnat_ugn/gnat_and_program_execution.rst: Remove
515 documentation of gnatelim.
517 2019-08-14 Bob Duff <duff@adacore.com>
519 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
520 warning to the Sloc of the first pragma argument, rather than to
521 the pragma itself. This is to make pragmas processed after the
522 back end use the same Sloc as pragmas processed earlier, in the
523 front end. There's no reason for this discrepancy, and it
524 hinders further work on this ticket.
526 2019-08-14 Bob Duff <duff@adacore.com>
528 * sem.ads (Inside_A_Generic): Remove the ??? comment.
530 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

536 Set_Delay_Subprogram_Descriptors instead of Delay_Descriptors
539 2019-08-14 Bob Duff <duff@adacore.com>
541 * exp_aggr.adb (Init_Hidden_Discriminants): Avoid processing the
542 wrong discriminant, which could be of the wrong type.

1223 'Valid as a replacement for a range check on a discrete type
1224 when the bounds of the range are given by type conversions,
1225 because in such a case there are distinct types involved and the
1226 subbested attribute replacement would be misplaced.
1228 2019-07-22 Yannick Moy <moy@adacore.com>
1230 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,
1231 Is_Subpath_Expression): Add parameter Is_Traversal to adapt

1268 * sem_res.adb (Resolve_Actuals): Replace code that displaces the

1292 libgnat/s-valwch.ads: Change categorization of packages that
1293 implement attribute 'Value from Pure to Preelaborate, to prevent
1294 undesirable optimizations when the evaluation of the attribute
1295 raises Constraint_Error, but subsequent use of the result of
1296 this evsaluation is removed by a subsequent optimization.

1314 Index_Table with range Natural'First .. Names'Length since in
1315 the worst case all the literals of the enumeration type would be
1316 single letter literals and the Table built by the frontend would
1317 have as many components as the length of the names string. As a
1318 result of this enhancement, the internal tables declared using
1319 Index_Table have a length closer to the real needs, thus
1320 avoiding the declaration of large arrays on 32-bit CCG targets.

1432 stqtement list, in which the prefix of the selected component is
1433 the actual for an out parameter.
