3 * adaint.c (__gnat_to_gm_time): On _WIN32, don't round time up
6 2019-08-20 Ed Schonberg <schonberg@adacore.com>
8 * sem_ch3.adb (Analyze_Object_Declaration): If actual type is
9 private and distinct from nominal type in declaration, propagate
10 flags Is_Constr_Subt_For_U_Nominal and _UN_Aliased to full view
13 2019-08-20 Ed Schonberg <schonberg@adacore.com>
15 * exp_attr.adb (Expand_Loop_Entry_Attribute): When expanding a
16 loop entry attribute for a while_loop we construct a function
17 that incorporates the expanded condition of the loop. The itypes
18 that may be generated in that expansion must carry the scope of
19 the constructed function for proper handling in gigi.
21 2019-08-20 Ed Schonberg <schonberg@adacore.com>
23 * exp_disp.adb (Build_Class_Wide_Check, Replace_Formals): When a
24 dispatching call tp a subprogram with a class-wide precondition
25 occurrs in the same declarative part as the ancestor subprogram
26 being called, the`expression for the precondition has not been
27 analyzed yet. Such a call may appear, e.g. in an expression
28 function. In that case, the replacement of formals by actuals in
29 the call cannot use the formal entities of the subprogram being
30 called, and the occurrence of the formals in the expression must
31 be located by name (Chars fields) as would be done at a later
32 freeze point, when the expression is resolved in the context of
33 the subprogram itself.
35 2019-08-20 Bob Duff <duff@adacore.com>
37 * sem_prag.adb (Persistent_BSS): If an initialization is present
38 because of Initialize_Scalars or Normalize_Scalars, generate an
39 implicit pragma Suppress_Initialization to remove that, because
40 initialization is not allowed for these variables. Other
41 initializations remain illegal.
43 2019-08-20 Gary Dismukes <dismukes@adacore.com>
45 * sem_ch3.adb (OK_For_Limited_Init_In_05): In the case of type
46 conversions, apply the recursive call to the Original_Node of
47 the expression Exp rather than the Expression of the
48 Original_Node, in the case where Exp has been rewritten;
49 otherwise, when Original_Node is the same as Exp, apply the
50 recursive call to the Expression.
51 (Check_Initialization): Revise condition for special check on
52 type conversions of limited function calls to test Original_Node
53 (avoiding spurious errors on expanded unchecked conversions
54 applied to build-in-place dispatching calls).
56 2019-08-20 Patrick Bernardi <bernardi@adacore.com>
58 * exp_aggr.adb (Expand_Record_Aggregate): Always convert a
59 record Aggregate to assignment statements if the option
60 Aggregate_Individually_Assign is set.
61 * opt.ads (Aggregate_Individually_Assign): New option.
62 * par-prag.adb (Prag): Add Pragma_Aggregate_Individually_Assign.
63 * sem_prag.adb (Analyze_Pragma): Likewise.
64 * snames.ads-tmpl: Add Pragma_Aggregate_Individually_Assign and
65 Name_Aggregate_Individually_Assign.
66 * doc/gnat_rm/implementation_defined_pragmas.rst: Document
67 pragma Aggregate_Individually_Assign.
68 * gnat_rm.texi: Regenerate.
70 2019-08-20 Bob Duff <duff@adacore.com>
72 * par-ch4.adb: Minor wording change in error messages.
73 * sem_aggr.adb (Resolve_Delta_Aggregate): Emit an error for Ada
74 versions prior to Ada 2020.
76 2019-08-20 Bob Duff <duff@adacore.com>
78 * freeze.adb (Is_Atomic_VFA_Aggregate): Make the temp for
79 initialization of the atomic variable be constant. This is
80 cleaner, and might improve efficiency.
82 2019-08-20 Eric Botcazou <ebotcazou@adacore.com>
84 * repinfo.adb (List_Record_Info): In -gnatR4 mode, set the
85 relevant flag on the implicit base type of a record subtype.
87 2019-08-20 Bob Duff <duff@adacore.com>
89 * sem_eval.adb (Expr_Value): Implement the case of an unchecked
90 conversion of a static expression.
92 2019-08-20 Bob Duff <duff@adacore.com>
94 * sem_ch13.adb (Is_Null_Array): New function, used to detect the
95 null array case; used to warn about uncheckedly converting to a
96 zero-sized array. It is unfortunate that we can't just check
97 the size, and warn on all cases of converting from a
98 nonzero-sized type to a zero-sized one. That's because "0" means
99 two different things: "size is zero" and "size is unknown".
100 Until we fix that design flaw, we need this more targeted fix.
102 2019-08-20 Bob Duff <duff@adacore.com>
104 * libgnat/a-cborma.adb, libgnat/a-cborse.adb (Clear): Repeatedly
105 call Delete. This avoids clearing the free list, which
106 substantially speeds up future Delete operations.
108 2019-08-20 Bob Duff <duff@adacore.com>
110 * sem_ch13.adb (Component_Order_Check): New procedure to check
111 for out-of-order clauses.
112 * warnsw.ads, warnsw.adb: New -gnatw_r switch.
113 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
115 * gnat_ugn.texi: Regenerate.
117 2019-08-20 Bob Duff <duff@adacore.com>
119 * sem_ch13.adb (Object_Size): Give an error for zero. It really
120 rubs me the wrong way that we don't honor "for T'Object_Size use
121 0;", but it's not important enough to fix. In any case, if we're
122 not going to obey the clause, we should give an error.
124 2019-08-20 Bob Duff <duff@adacore.com>
126 * errout.adb (Error_Msg_Internal): Set Warn_Err in case of
128 * erroutc.adb (Output_Msg_Text): Do Warnings_Treated_As_Errors
129 processing and [warning-as-error] modification for style
130 messages. Clean up code, simplify, remove unnecessary block
131 statement, add renaming of table entry.
132 * erroutc.ads (Warning_Treated_As_Error): Fix comment: no such
133 thing as Set_Warning_As_Error.
134 * opt.ads: Clean up comments and move related declarations near
136 * par-prag.adb: Process Warning_As_Error. This is necessary
137 because many style warning happen during parsing.
138 * sem_prag.adb: Use new Acquire_Warning_Match_String.
139 * sem_util.ads, sem_util.adb (Acquire_Warning_Match_String): New
140 function shared by par-prag.adb and sem_prag.adb. Replaces the
141 procedure in sem_prag.adb. Avoid use of global variables.
142 * stringt.ads, stringt.adb (To_String): New function to convert
144 * doc/gnat_rm/implementation_defined_pragmas.rst: Document the
146 * gnat_rm.texi: Regenerate.
148 2019-08-20 Eric Botcazou <ebotcazou@adacore.com>
150 * lib.ads: Add with clause for GNAT.HTable.
151 Add pragma Inline for Is_Loaded and alphabetize the list.
152 (Unit_Name_Table_Size): New constant.
153 (Unit_Name_Header_Num): New subtype.
154 (Unit_Name_Hash): New function declaration.
155 (Unit_Names): New simple hash table.
156 (Init_Unit_Name): New procedure declaration.
157 * lib.adb (Set_Unit_Name): Unregister the old name in the table,
158 if any, and then register the new name.
159 (Init_Unit_Name): New procedure.
160 (Is_Loaded): Reimplement using a lookup in the names table.
161 (Remove_Unit): Unregister the name.
162 (Unit_Name_Hash): New function.
163 * lib-load.adb (Create_Dummy_Package_Unit): Call Init_Unit_Name.
164 (Load_Unit): Use a lookup in the names table to find out whether
165 the unit has already been loaded. Call Init_Unit_Name and then
166 Remove_Unit if the loading has failed.
167 (Make_Child_Decl_Unit): Call Init_Unit_Name.
168 (Make_Instance_Unit): Likewise.
169 * lib-writ.adb (Ensure_System_Dependency): Likewise.
171 2019-08-20 Bob Duff <duff@adacore.com>
173 * sem_ch13.adb (Record_Hole_Check): Initialize After_Last.
175 2019-08-20 Piotr Trojanek <trojanek@adacore.com>
177 * impunit.adb (Get_Kind_Of_Unit): Revert change for adapting
178 this routine for gnatprove.
180 2019-08-20 Arnaud Charlet <charlet@adacore.com>
182 * doc/gnat_rm/implementation_defined_pragmas.rst: Document
183 requirements for Pragma Lock_Free.
184 * gnat_rm.texi: Regenerate.
186 2019-08-20 Philippe Gil <gil@adacore.com>
188 * bindgen.adb (Gen_Main): Set gnat_argc/gnat_argv to argc/argv
189 only when still uninitialized.
191 2019-08-20 Bob Duff <duff@adacore.com>
193 * libgnat/g-comlin.ads (Exit_From_Command_Line): Fix
194 documentation for GNAT.Command_Line.
196 2019-08-20 Pierre-Marie de Rodat <derodat@adacore.com>
199 * gcc-interface/lang.opt (-fdump-scos): Add missing dot at the
200 end of the documentation.
202 2019-08-20 Richard Sandiford <richard.sandiford@arm.com>
204 * gcc-interface/misc.c (default_pass_by_ref): Update call to
207 2019-08-19 Bob Duff <duff@adacore.com>
209 * doc/gnat_rm/implementation_advice.rst: Fix documentation for
210 stream oriented attributes.

213 2019-08-19 Gary Dismukes <dismukes@adacore.com>
215 * einfo.ads (E_Function, E_Procedure): Update comments to
216 reflect that Renamed_Entity is also used for nongeneric
219 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
221 * sem_prag.adb (Is_Before_First_Decl): Deal with rewritten
224 2019-08-19 Bob Duff <duff@adacore.com>
226 * sem_warn.adb (Warn_On_Unreferenced_Entity): Suppress warning
227 on formal parameters of dispatching operations.
229 2019-08-19 Ed Schonberg <schonberg@adacore.com>
231 * sem_res.adb (Resolve_Call): A call to an expression function
232 freezes when expander is active, unless the call appears within
233 the body of another expression function,
235 2019-08-19 Dmitriy Anisimkov <anisimko@adacore.com>
237 * libgnat/s-os_lib.ads, libgnat/s-os_lib.adb (To_Ada, To_C): New
240 2019-08-19 Bob Duff <duff@adacore.com>
242 * exp_attr.adb (Attribute_Valid): Correct the handling of
243 private types where the full type is modular. System.Address is
244 an example. Otherwise, we convert uncheckedly to a signed type,
245 so we get an incorrect range 0 .. -1, for which all values will
246 fail. The 'Valid attribute is illegal for such types, but we
247 generate such illegal attribute_references for 'Valid_Scalars,
248 and we generate 'Valid_Scalars when the -gnateV switch is used.
249 Rename Btyp --> PBtyp to avoid hiding the outer Btyp, which was
251 * libgnat/a-except.adb: Set the Exception_Raised component.
252 Otherwise, we have incorrect reads of invalid data.
254 2019-08-19 Pierre-Marie de Rodat <derodat@adacore.com>
256 * libgnat/a-cgaaso.ads, libgnat/a-cgarso.ads,

265 ada_target_properties.
267 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
269 * inline.adb (Add_Inlined_Body): Do not special-case instances
270 that are compilation units.
271 (Add_Pending_Instantiation): Likewise.
272 (Instantiate_Body): Skip instantiations that are compilation
273 units and have already been performed.
274 * sem_ch12.adb (Needs_Body_Instantiated): Do not special-case
275 instances that are compilation units.
276 (Load_Parent_Of_Generic): Be prepared for parent that is a
277 compilation unit but whose instantiation node has not been

283 Called_Pending_Instantiations.
285 2019-08-19 Ed Schonberg <schonberg@adacore.com>
287 * sem_ch6.adb (Check_Synchronized_Overriding): Complete
288 predicate that applies legality check in 9.4 (11.9/2): if an
289 inherited subprogram is implemented by a protected procedure or
290 entry, its first paarameter must be out, in_out or
293 2019-08-19 Javier Miranda <miranda@adacore.com>
296 * exp_atag.ads, exp_atag.adb (Build_Inherit_Predefined_Prims):
297 Adding formal to specify how many predefined primitives are
298 inherited from the parent type.
299 * exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
300 (Make_Secondary_DT): Compute the number of predefined primitives
301 of all tagged types (including tagged types not defined at
302 library level). Previously we unconditionally relied on the
303 Max_Predef_Prims constant value when building the dispatch
304 tables of tagged types not defined at library level (thus
305 consuming more memory for their dispatch tables than required).
306 (Make_DT): Compute the number of predefined primitives that must
307 be inherited from their parent type when building the dispatch
308 tables of tagged types not defined at library level. Previously
309 we unconditionally relied on the Max_Predef_Prims constant value
310 when building the dispatch tables of tagged types not defined at
311 library level (thus copying more data than required from the
314 2019-08-19 Bob Duff <duff@adacore.com>
316 * sem_ch13.adb (Record_Hole_Check): Procedure to check for holes
317 that incudes processing type extensions. A type extension is
318 processed by first calling Record_Hole_Check recursively on the
319 parent type to compute the bit number after the last component
322 2019-08-19 Gary Dismukes <dismukes@adacore.com>
324 * checks.adb (Length_Mismatch_Info_Message): New function in
325 Selected_Length_Checks to return a message indicating the
326 element counts for the mismatched lengths for a failed
327 compile-time length check.
328 (Plural_Or_Singular_Ending): Support function in
329 Length_Mismatch_Info_Message to return either "" or "s", for
330 concatenating to the end of words.
331 (Selected_Length_Checks): Pass the result of
332 Length_Mismatch_Info_Message as an extra warning message to
333 Compile_Time_Constraint_Error to indicate the mismatched lengths
334 for a failed compile-time length check.
335 * sem_util.ads (Compile_Time_Constraint_Error): Add an optional
336 message formal (Extra_Msg), defaulted to the empty string.
337 * sem_util.adb (Compile_Time_Constraint_Error): Output an extra
338 message following the main warning message (when Extra_Msg is
339 not the empty string).
341 2019-08-19 Patrick Bernardi <bernardi@adacore.com>
343 * socket.c: Removed the redefinition of getaddrinfo, getnameinfo
344 and freeaddrinfo to internal VxWorks kernel calls because they
345 are, well, internal kernel calls and cannot be called from RTPs.
346 VxWorks provides the necessary components to call these routines
349 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
351 * exp_dist.adb (Is_Generic_Actual_Subtype): New predicate.
352 (Build_From_Any_Call, Build_To_Any_Call, Build_TypeCode_Call):
353 Use it instead of Is_Generic_Actual_Type flag to detect subtypes
354 representing generic actual types.
356 2019-08-19 Ed Schonberg <schonberg@adacore.com>
358 * sem_warn.adb (Check_References, Generic_Body_Formal): When a
359 formal parameter of a generic subprogram is not referenced in
360 the body, place the corresponding warning on the corresponding
361 entity in the specification of the generic body, as is done for
362 non-generic subprograms.
364 2019-08-19 Bob Duff <duff@adacore.com>
366 * errout.ads (Size_Too_Small_Message): New constant.
367 * errout.adb, freeze.adb, sem_ch13.adb: Use it.
369 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
371 * exp_dist.adb (Build_Package_Stubs): Do not specifically visit
372 the declarations of an N_Subprogram_Instantiation node.

384 local variable if needed.
386 2019-08-19 Claire Dross <dross@adacore.com>
388 * sem_spark.ads, sem_spark.adb (Is_Pledge_Function): New
389 parameter of the generic. Function used to decide whether a
390 function is a pledge function.
391 (Check_Not_Borrowed): Disable check inside the second parameter
392 of a pledge function for the path borrowed by the first
393 parameter. Also disable checks for entities inside a Global

412 base type if the bounds in the derived type declaration are
413 literals of the type.

430 * gcc-interface/trans.c (Acc_Loop_to_gnu): Return the openacc
431 BIND_EXPR node we have constructed on purpose. Remove unused
434 2019-08-19 Pierre-Marie de Rodat <derodat@adacore.com>
436 * gcc-interface/lang.opt (fdump-scos): Define.
437 * gcc-interface/misc.c (gnat_handle_option): Handle
440 2019-08-14 Joffrey Huguet <huguet@adacore.com>
442 * libgnat/a-cofuba.ads: Add a Length attribute to type
443 Container. Add a type Array_Base which replaces the previous
444 Elements attribute of Container.
445 (Content_Init): New subprogram. It is used to initialize the
446 Base attribute of Container.
447 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
448 resize the underlying array of a container if necessary.
449 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,
450 Union): Update to match changes in type declarations.
451 (Add): Modify body to damp the time and space cost in a specific
453 (Content_Init): New subprogram. It is used to initialize the
454 Base attribute of Container.
455 (Remove): Modify body to damp the time and space cost in a

461 and do not give an error.

463 corresponding documentation.

469 in the comparison against the maximum number of instantiations.
471 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
473 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
474 in the comparison against the maximum number of instantiations.
476 2019-08-14 Ed Schonberg <schonberg@adacore.com>
478 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
479 involves a Ghost aspect it may have been replaced by a null
480 statement; use the original node to find next Rep_Item.
481 * repinfo.adb (List_Entities): Do not list an Ignored
482 Ghost_Entity, for which information may have been deleted.
484 2019-08-14 Bob Duff <duff@adacore.com>
486 * sem_prag.ads, sem_prag.adb
487 (Process_Compile_Time_Warning_Or_Error): In parameterless
488 version, improve detection of whether we are in a generic unit
489 to cover the case of an instance within a generic unit.
490 (Process_Compile_Time_Warning_Or_Error): Rename the
491 two-parameter version to be
492 Validate_Compile_Time_Warning_Or_Error, and do not export it.
493 Issue a warning if the condition is not known at compile time.
494 The key point is that the warning must be given only for pragmas
495 deferred to the back end, because the back end discovers
496 additional values that are known at compile time. Previous
497 changes in this ticket have enabled this by deferring to the
498 back end without checking for special cases such as 'Size.
499 (Validate_Compile_Time_Warning_Or_Error): Rename to be
500 Defer_Compile_Time_Warning_Error_To_BE.
501 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):
502 Add new switches -gnatw_c and -gnatw_C to control the above
504 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
505 Document new switches.
506 * gnat_ugn.texi: Regenerate.

513 2019-08-14 Bob Duff <duff@adacore.com>
515 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
516 protected functions to get rid of spurious error. The
517 transformation done by this procedure triggers legality errors
518 in the generated code in this case.
520 2019-08-14 Bob Duff <duff@adacore.com>
522 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
523 processing to the back end in all cases where the pragma's
524 condition is not known at compile time during the front end
525 (except in generics), as opposed to detecting 'Size attributes
526 and the like. This ensures that we take advantage of whatever
527 can be compile-time known after running the back end, as opposed
528 to having the front end guess what the back end can do. Remove
529 a little duplicated code at the call site.
530 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
531 Elists while in Validate_Compile_Time_Warning_Errors, because it
532 does analysis and name resolution, which sometimes involves
535 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
537 * einfo.ads (Is_Called): Document new usage on E_Package
539 * einfo.adb (Is_Called): Accept E_Package entities.
540 (Set_Is_Called): Likewise.
541 * exp_ch6.adb (Expand_Call_Helper): Move code dealing with
542 instances for back-end inlining to Add_Inlined_Body.
543 * inline.ads: Remove with clauses for Alloc and Table.

561 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
562 (Add_Pending_Instantiation): Move the defence against ludicruous

605 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
606 warning to the Sloc of the first pragma argument, rather than to
607 the pragma itself. This is to make pragmas processed after the

609 front end. There's no reason for this discrepancy, and it
610 hinders further work on this ticket.

691 expression includes the implicit declaration of the loop
692 parameter. When a quantified expression is copied during
693 expansion, for example when building the precondition code from

1309 'Valid as a replacement for a range check on a discrete type
1310 when the bounds of the range are given by type conversions,
1311 because in such a case there are distinct types involved and the
1312 subbested attribute replacement would be misplaced.
1314 2019-07-22 Yannick Moy <moy@adacore.com>
1316 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,
1317 Is_Subpath_Expression): Add parameter Is_Traversal to adapt

1354 * sem_res.adb (Resolve_Actuals): Replace code that displaces the

1378 libgnat/s-valwch.ads: Change categorization of packages that
1379 implement attribute 'Value from Pure to Preelaborate, to prevent
1380 undesirable optimizations when the evaluation of the attribute
1381 raises Constraint_Error, but subsequent use of the result of
1382 this evsaluation is removed by a subsequent optimization.

1400 Index_Table with range Natural'First .. Names'Length since in
1401 the worst case all the literals of the enumeration type would be
1402 single letter literals and the Table built by the frontend would
1403 have as many components as the length of the names string. As a
1404 result of this enhancement, the internal tables declared using
1405 Index_Table have a length closer to the real needs, thus
1406 avoiding the declaration of large arrays on 32-bit CCG targets.
