3 * doc/gnat_rm/implementation_advice.rst: Fix documentation for
4 stream oriented attributes.
5 * gnat_rm.texi: Regenerate.
7 2019-08-19 Gary Dismukes <dismukes@adacore.com>
9 * einfo.ads (E_Function, E_Procedure): Update comments to
10 reflect that Renamed_Entity is also used for nongeneric

31 * libgnat/s-os_lib.ads, libgnat/s-os_lib.adb (To_Ada, To_C): New
34 2019-08-19 Bob Duff <duff@adacore.com>
36 * exp_attr.adb (Attribute_Valid): Correct the handling of
37 private types where the full type is modular. System.Address is
38 an example. Otherwise, we convert uncheckedly to a signed type,
39 so we get an incorrect range 0 .. -1, for which all values will
40 fail. The 'Valid attribute is illegal for such types, but we
41 generate such illegal attribute_references for 'Valid_Scalars,
42 and we generate 'Valid_Scalars when the -gnateV switch is used.
43 Rename Btyp --> PBtyp to avoid hiding the outer Btyp, which was
45 * libgnat/a-except.adb: Set the Exception_Raised component.
46 Otherwise, we have incorrect reads of invalid data.

81 * sem_ch6.adb (Check_Synchronized_Overriding): Complete
82 predicate that applies legality check in 9.4 (11.9/2): if an
83 inherited subprogram is implemented by a protected procedure or
84 entry, its first paarameter must be out, in_out or

91 Adding formal to specify how many predefined primitives are
92 inherited from the parent type.
93 * exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
94 (Make_Secondary_DT): Compute the number of predefined primitives
95 of all tagged types (including tagged types not defined at
96 library level). Previously we unconditionally relied on the
97 Max_Predef_Prims constant value when building the dispatch
98 tables of tagged types not defined at library level (thus
99 consuming more memory for their dispatch tables than required).
100 (Make_DT): Compute the number of predefined primitives that must
101 be inherited from their parent type when building the dispatch
102 tables of tagged types not defined at library level. Previously
103 we unconditionally relied on the Max_Predef_Prims constant value
104 when building the dispatch tables of tagged types not defined at
105 library level (thus copying more data than required from the
108 2019-08-19 Bob Duff <duff@adacore.com>
110 * sem_ch13.adb (Record_Hole_Check): Procedure to check for holes
111 that incudes processing type extensions. A type extension is
112 processed by first calling Record_Hole_Check recursively on the
113 parent type to compute the bit number after the last component
116 2019-08-19 Gary Dismukes <dismukes@adacore.com>
118 * checks.adb (Length_Mismatch_Info_Message): New function in
119 Selected_Length_Checks to return a message indicating the
120 element counts for the mismatched lengths for a failed
121 compile-time length check.
122 (Plural_Or_Singular_Ending): Support function in
123 Length_Mismatch_Info_Message to return either "" or "s", for
124 concatenating to the end of words.
125 (Selected_Length_Checks): Pass the result of
126 Length_Mismatch_Info_Message as an extra warning message to
127 Compile_Time_Constraint_Error to indicate the mismatched lengths
128 for a failed compile-time length check.
129 * sem_util.ads (Compile_Time_Constraint_Error): Add an optional
130 message formal (Extra_Msg), defaulted to the empty string.
131 * sem_util.adb (Compile_Time_Constraint_Error): Output an extra
132 message following the main warning message (when Extra_Msg is
133 not the empty string).
135 2019-08-19 Patrick Bernardi <bernardi@adacore.com>
137 * socket.c: Removed the redefinition of getaddrinfo, getnameinfo
138 and freeaddrinfo to internal VxWorks kernel calls because they
139 are, well, internal kernel calls and cannot be called from RTPs.
140 VxWorks provides the necessary components to call these routines
143 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
145 * exp_dist.adb (Is_Generic_Actual_Subtype): New predicate.
146 (Build_From_Any_Call, Build_To_Any_Call, Build_TypeCode_Call):
147 Use it instead of Is_Generic_Actual_Type flag to detect subtypes
148 representing generic actual types.
150 2019-08-19 Ed Schonberg <schonberg@adacore.com>
152 * sem_warn.adb (Check_References, Generic_Body_Formal): When a
153 formal parameter of a generic subprogram is not referenced in
154 the body, place the corresponding warning on the corresponding
155 entity in the specification of the generic body, as is done for
156 non-generic subprograms.
158 2019-08-19 Bob Duff <duff@adacore.com>
160 * errout.ads (Size_Too_Small_Message): New constant.

183 parameter of the generic. Function used to decide whether a
184 function is a pledge function.
185 (Check_Not_Borrowed): Disable check inside the second parameter
186 of a pledge function for the path borrowed by the first
187 parameter. Also disable checks for entities inside a Global

224 * gcc-interface/trans.c (Acc_Loop_to_gnu): Return the openacc
225 BIND_EXPR node we have constructed on purpose. Remove unused

230 * gcc-interface/lang.opt (fdump-scos): Define.
231 * gcc-interface/misc.c (gnat_handle_option): Handle
234 2019-08-14 Joffrey Huguet <huguet@adacore.com>
236 * libgnat/a-cofuba.ads: Add a Length attribute to type
237 Container. Add a type Array_Base which replaces the previous
238 Elements attribute of Container.
239 (Content_Init): New subprogram. It is used to initialize the
240 Base attribute of Container.
241 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
242 resize the underlying array of a container if necessary.
243 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,
244 Union): Update to match changes in type declarations.
245 (Add): Modify body to damp the time and space cost in a specific
247 (Content_Init): New subprogram. It is used to initialize the
248 Base attribute of Container.
249 (Remove): Modify body to damp the time and space cost in a
252 2019-08-14 Bob Duff <duff@adacore.com>
254 * sem_ch13.adb (Get_Alignment_Value): Return 1 for Alignment 0,
255 and do not give an error.
256 * doc/gnat_rm/representation_clauses_and_pragmas.rst: Update the
257 corresponding documentation.

262 * inline.adb (Add_Pending_Instantiation): Fix off-by-one error
263 in the comparison against the maximum number of instantiations.
265 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
267 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
268 in the comparison against the maximum number of instantiations.
270 2019-08-14 Ed Schonberg <schonberg@adacore.com>
272 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
273 involves a Ghost aspect it may have been replaced by a null
274 statement; use the original node to find next Rep_Item.
275 * repinfo.adb (List_Entities): Do not list an Ignored
276 Ghost_Entity, for which information may have been deleted.
278 2019-08-14 Bob Duff <duff@adacore.com>
280 * sem_prag.ads, sem_prag.adb
281 (Process_Compile_Time_Warning_Or_Error): In parameterless
282 version, improve detection of whether we are in a generic unit
283 to cover the case of an instance within a generic unit.
284 (Process_Compile_Time_Warning_Or_Error): Rename the
285 two-parameter version to be
286 Validate_Compile_Time_Warning_Or_Error, and do not export it.
287 Issue a warning if the condition is not known at compile time.
288 The key point is that the warning must be given only for pragmas
289 deferred to the back end, because the back end discovers
290 additional values that are known at compile time. Previous
291 changes in this ticket have enabled this by deferring to the
292 back end without checking for special cases such as 'Size.
293 (Validate_Compile_Time_Warning_Or_Error): Rename to be
294 Defer_Compile_Time_Warning_Error_To_BE.
295 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):
296 Add new switches -gnatw_c and -gnatw_C to control the above
298 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
299 Document new switches.

302 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
304 * sem_ch12.adb (Might_Inline_Subp): Rework comment and restrict
305 the shortcut based on Is_Inlined to the back-end inlining case.
307 2019-08-14 Bob Duff <duff@adacore.com>
309 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
310 protected functions to get rid of spurious error. The
311 transformation done by this procedure triggers legality errors
312 in the generated code in this case.
314 2019-08-14 Bob Duff <duff@adacore.com>
316 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
317 processing to the back end in all cases where the pragma's
318 condition is not known at compile time during the front end
319 (except in generics), as opposed to detecting 'Size attributes
320 and the like. This ensures that we take advantage of whatever
321 can be compile-time known after running the back end, as opposed
322 to having the front end guess what the back end can do. Remove
323 a little duplicated code at the call site.
324 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
325 Elists while in Validate_Compile_Time_Warning_Errors, because it
326 does analysis and name resolution, which sometimes involves
329 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
331 * einfo.ads (Is_Called): Document new usage on E_Package

337 * inline.ads: Remove with clauses for Alloc and Table.
338 (Pending_Instantiations): Move to...
339 * inline.adb: Add with clauses for Alloc, Uintp, Table and
341 (Backend_Instances): New variable.
342 (Pending_Instantiations): ...here.
343 (Called_Pending_Instantiations): New table.
344 (Node_Table_Size): New constant.
345 (Node_Header_Num): New subtype.
346 (Node_Hash): New function.
347 (To_Pending_Instantiations): New hash table.
348 (Add_Inlined_Body): Bail out early for subprograms in the main
349 unit or subunit. Likewise if the Is_Called flag is set. If the
350 subprogram is an instance, invoke Add_Inlined_Instance. Call
351 Set_Is_Called earlier. If the subrogram is within an instance,
352 invoke Add_Inlined_Instance. Also deal with the case where the
353 call itself is within an instance.
354 (Add_Inlined_Instance): New procedure.
355 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
356 (Add_Pending_Instantiation): Move the defence against ludicruous
357 number of instantiations to here. When back-end inlining is
358 enabled, associate an instantiation with its index in table and
359 mark a few selected kinds of instantiations as always needed.
360 (Initialize): Set Backend_Instances to No_Elist.
361 (Instantiate_Body): New procedure doing the work extracted
363 (Instantiate_Bodies): ...here. When back-end inlining is
364 enabled, loop over Called_Pending_Instantiations instead of
365 Pending_Instantiations.
366 (Is_Nested): Minor tweak.
367 (List_Inlining_Info): Also list the contents of
369 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
370 is set and otherwise set it before returning true.
371 (Analyze_Package_Instantiation): Remove the defence against
372 ludicruous number of instantiations. Invoke
373 Remove_Dead_Instance instead of doing the removal manually if
374 there is a guaranteed ABE.
376 2019-08-14 Gary Dismukes <dismukes@adacore.com>
378 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
379 of an interface type, create an expression function (that
380 returns False) rather than declaring an abstract function.
381 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
382 False unconditionally at the start of the loop creating wrappers
383 for inherited operations.
385 2019-08-14 Bob Duff <duff@adacore.com>
387 * table.adb: Assert that the table is not locked when increasing
388 Last, even if it doesn't cause reallocation. In other words,
389 assert that on operations that MIGHT cause reallocation.
390 * table.ads: Fix comment accordingly.
392 2019-08-14 Arnaud Charlet <charlet@adacore.com>
394 * doc/gnat_ugn/gnat_and_program_execution.rst: Remove
395 documentation of gnatelim.
397 2019-08-14 Bob Duff <duff@adacore.com>
399 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
400 warning to the Sloc of the first pragma argument, rather than to
401 the pragma itself. This is to make pragmas processed after the
402 back end use the same Sloc as pragmas processed earlier, in the
403 front end. There's no reason for this discrepancy, and it
404 hinders further work on this ticket.
406 2019-08-14 Bob Duff <duff@adacore.com>
408 * sem.ads (Inside_A_Generic): Remove the ??? comment.
410 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

474 function. Use it to recurse on the private dependent entities

482 2019-08-14 Ed Schonberg <schonberg@adacore.com>
484 * sem_util.adb (New_Copy_Tree, Visit_Entity): A quantified
485 expression includes the implicit declaration of the loop
486 parameter. When a quantified expression is copied during
487 expansion, for example when building the precondition code from
488 the generated pragma, a new loop parameter must be created for
489 the new tree, to prevent duplicate declarations for the same

1103 'Valid as a replacement for a range check on a discrete type
1104 when the bounds of the range are given by type conversions,
1105 because in such a case there are distinct types involved and the
1106 subbested attribute replacement would be misplaced.
1108 2019-07-22 Yannick Moy <moy@adacore.com>
1110 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,
1111 Is_Subpath_Expression): Add parameter Is_Traversal to adapt

1144 * sprint.ads: Fix pasto in comment.
1146 2019-07-22 Javier Miranda <miranda@adacore.com>
1148 * sem_res.adb (Resolve_Actuals): Replace code that displaces the

1155 * sprint.adb (Sprint_Node_Actual)

1171 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
1172 libgnat/s-valwch.ads: Change categorization of packages that
1173 implement attribute 'Value from Pure to Preelaborate, to prevent
1174 undesirable optimizations when the evaluation of the attribute
1175 raises Constraint_Error, but subsequent use of the result of
1176 this evsaluation is removed by a subsequent optimization.
1178 2019-07-22 Ed Schonberg <schonberg@adacore.com>
1180 * sem_warn.adb (Check_References): Do not emit s warning on a
1181 referenced entity with no explicit assignment if the type of the

1193 Image_Enumeration_16, Image_Enumeration_32): Define the index of
1194 Index_Table with range Natural'First .. Names'Length since in
1195 the worst case all the literals of the enumeration type would be
1196 single letter literals and the Table built by the frontend would
1197 have as many components as the length of the names string. As a
1198 result of this enhancement, the internal tables declared using
1199 Index_Table have a length closer to the real needs, thus
1200 avoiding the declaration of large arrays on 32-bit CCG targets.

1237 * sem_ch3.adb (Convert_Bound): Subsidiary of
1238 Floating_Point_Type_Declaration, to handle properly range
