63 * libgnat/s-os_lib.ads, libgnat/s-os_lib.adb (To_Ada, To_C): New
66 2019-08-19 Bob Duff <duff@adacore.com>
68 * exp_attr.adb (Attribute_Valid): Correct the handling of
69 private types where the full type is modular. System.Address is
70 an example. Otherwise, we convert uncheckedly to a signed type,
71 so we get an incorrect range 0 .. -1, for which all values will
72 fail. The 'Valid attribute is illegal for such types, but we
73 generate such illegal attribute_references for 'Valid_Scalars,
74 and we generate 'Valid_Scalars when the -gnateV switch is used.
75 Rename Btyp --> PBtyp to avoid hiding the outer Btyp, which was
77 * libgnat/a-except.adb: Set the Exception_Raised component.
78 Otherwise, we have incorrect reads of invalid data.

113 * sem_ch6.adb (Check_Synchronized_Overriding): Complete
114 predicate that applies legality check in 9.4 (11.9/2): if an
115 inherited subprogram is implemented by a protected procedure or
116 entry, its first paarameter must be out, in_out or
119 2019-08-19 Javier Miranda <miranda@adacore.com>
122 * exp_atag.ads, exp_atag.adb (Build_Inherit_Predefined_Prims):
123 Adding formal to specify how many predefined primitives are
124 inherited from the parent type.
125 * exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
126 (Make_Secondary_DT): Compute the number of predefined primitives
127 of all tagged types (including tagged types not defined at
128 library level). Previously we unconditionally relied on the
129 Max_Predef_Prims constant value when building the dispatch
130 tables of tagged types not defined at library level (thus
131 consuming more memory for their dispatch tables than required).
132 (Make_DT): Compute the number of predefined primitives that must
133 be inherited from their parent type when building the dispatch
134 tables of tagged types not defined at library level. Previously
135 we unconditionally relied on the Max_Predef_Prims constant value
136 when building the dispatch tables of tagged types not defined at
137 library level (thus copying more data than required from the
140 2019-08-19 Bob Duff <duff@adacore.com>
142 * sem_ch13.adb (Record_Hole_Check): Procedure to check for holes
143 that incudes processing type extensions. A type extension is
144 processed by first calling Record_Hole_Check recursively on the
145 parent type to compute the bit number after the last component
148 2019-08-19 Gary Dismukes <dismukes@adacore.com>
150 * checks.adb (Length_Mismatch_Info_Message): New function in
151 Selected_Length_Checks to return a message indicating the
152 element counts for the mismatched lengths for a failed
153 compile-time length check.
154 (Plural_Or_Singular_Ending): Support function in
155 Length_Mismatch_Info_Message to return either "" or "s", for
156 concatenating to the end of words.
157 (Selected_Length_Checks): Pass the result of
158 Length_Mismatch_Info_Message as an extra warning message to
159 Compile_Time_Constraint_Error to indicate the mismatched lengths
160 for a failed compile-time length check.
161 * sem_util.ads (Compile_Time_Constraint_Error): Add an optional
162 message formal (Extra_Msg), defaulted to the empty string.
163 * sem_util.adb (Compile_Time_Constraint_Error): Output an extra
164 message following the main warning message (when Extra_Msg is
165 not the empty string).
167 2019-08-19 Patrick Bernardi <bernardi@adacore.com>
169 * socket.c: Removed the redefinition of getaddrinfo, getnameinfo
170 and freeaddrinfo to internal VxWorks kernel calls because they
171 are, well, internal kernel calls and cannot be called from RTPs.
172 VxWorks provides the necessary components to call these routines
175 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
177 * exp_dist.adb (Is_Generic_Actual_Subtype): New predicate.
178 (Build_From_Any_Call, Build_To_Any_Call, Build_TypeCode_Call):
179 Use it instead of Is_Generic_Actual_Type flag to detect subtypes
180 representing generic actual types.
182 2019-08-19 Ed Schonberg <schonberg@adacore.com>
184 * sem_warn.adb (Check_References, Generic_Body_Formal): When a
185 formal parameter of a generic subprogram is not referenced in
186 the body, place the corresponding warning on the corresponding
187 entity in the specification of the generic body, as is done for
188 non-generic subprograms.
190 2019-08-19 Bob Duff <duff@adacore.com>
192 * errout.ads (Size_Too_Small_Message): New constant.

266 2019-08-14 Joffrey Huguet <huguet@adacore.com>
268 * libgnat/a-cofuba.ads: Add a Length attribute to type
269 Container. Add a type Array_Base which replaces the previous
270 Elements attribute of Container.
271 (Content_Init): New subprogram. It is used to initialize the
272 Base attribute of Container.
273 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
274 resize the underlying array of a container if necessary.
275 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,
276 Union): Update to match changes in type declarations.
277 (Add): Modify body to damp the time and space cost in a specific
279 (Content_Init): New subprogram. It is used to initialize the
280 Base attribute of Container.
281 (Remove): Modify body to damp the time and space cost in a

294 * inline.adb (Add_Pending_Instantiation): Fix off-by-one error
295 in the comparison against the maximum number of instantiations.
297 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
299 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
300 in the comparison against the maximum number of instantiations.
302 2019-08-14 Ed Schonberg <schonberg@adacore.com>
304 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
305 involves a Ghost aspect it may have been replaced by a null
306 statement; use the original node to find next Rep_Item.
307 * repinfo.adb (List_Entities): Do not list an Ignored
308 Ghost_Entity, for which information may have been deleted.
310 2019-08-14 Bob Duff <duff@adacore.com>
312 * sem_prag.ads, sem_prag.adb
313 (Process_Compile_Time_Warning_Or_Error): In parameterless
314 version, improve detection of whether we are in a generic unit
315 to cover the case of an instance within a generic unit.
316 (Process_Compile_Time_Warning_Or_Error): Rename the
317 two-parameter version to be
318 Validate_Compile_Time_Warning_Or_Error, and do not export it.
319 Issue a warning if the condition is not known at compile time.
320 The key point is that the warning must be given only for pragmas
321 deferred to the back end, because the back end discovers
322 additional values that are known at compile time. Previous
323 changes in this ticket have enabled this by deferring to the
324 back end without checking for special cases such as 'Size.
325 (Validate_Compile_Time_Warning_Or_Error): Rename to be
326 Defer_Compile_Time_Warning_Error_To_BE.
327 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):
328 Add new switches -gnatw_c and -gnatw_C to control the above
330 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
331 Document new switches.

336 * sem_ch12.adb (Might_Inline_Subp): Rework comment and restrict
337 the shortcut based on Is_Inlined to the back-end inlining case.
339 2019-08-14 Bob Duff <duff@adacore.com>
341 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
342 protected functions to get rid of spurious error. The
343 transformation done by this procedure triggers legality errors
344 in the generated code in this case.
346 2019-08-14 Bob Duff <duff@adacore.com>
348 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
349 processing to the back end in all cases where the pragma's
350 condition is not known at compile time during the front end
351 (except in generics), as opposed to detecting 'Size attributes
352 and the like. This ensures that we take advantage of whatever
353 can be compile-time known after running the back end, as opposed
354 to having the front end guess what the back end can do. Remove
355 a little duplicated code at the call site.
356 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
357 Elists while in Validate_Compile_Time_Warning_Errors, because it
358 does analysis and name resolution, which sometimes involves
361 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
363 * einfo.ads (Is_Called): Document new usage on E_Package
365 * einfo.adb (Is_Called): Accept E_Package entities.
366 (Set_Is_Called): Likewise.
367 * exp_ch6.adb (Expand_Call_Helper): Move code dealing with
368 instances for back-end inlining to Add_Inlined_Body.
369 * inline.ads: Remove with clauses for Alloc and Table.
370 (Pending_Instantiations): Move to...
371 * inline.adb: Add with clauses for Alloc, Uintp, Table and
373 (Backend_Instances): New variable.
374 (Pending_Instantiations): ...here.
375 (Called_Pending_Instantiations): New table.
376 (Node_Table_Size): New constant.
377 (Node_Header_Num): New subtype.
378 (Node_Hash): New function.
379 (To_Pending_Instantiations): New hash table.
380 (Add_Inlined_Body): Bail out early for subprograms in the main
381 unit or subunit. Likewise if the Is_Called flag is set. If the
382 subprogram is an instance, invoke Add_Inlined_Instance. Call
383 Set_Is_Called earlier. If the subrogram is within an instance,
384 invoke Add_Inlined_Instance. Also deal with the case where the
385 call itself is within an instance.
386 (Add_Inlined_Instance): New procedure.
387 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
388 (Add_Pending_Instantiation): Move the defence against ludicruous
389 number of instantiations to here. When back-end inlining is
390 enabled, associate an instantiation with its index in table and
391 mark a few selected kinds of instantiations as always needed.
392 (Initialize): Set Backend_Instances to No_Elist.
393 (Instantiate_Body): New procedure doing the work extracted
395 (Instantiate_Bodies): ...here. When back-end inlining is
396 enabled, loop over Called_Pending_Instantiations instead of
397 Pending_Instantiations.
398 (Is_Nested): Minor tweak.
399 (List_Inlining_Info): Also list the contents of
401 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
402 is set and otherwise set it before returning true.
403 (Analyze_Package_Instantiation): Remove the defence against
404 ludicruous number of instantiations. Invoke
405 Remove_Dead_Instance instead of doing the removal manually if
406 there is a guaranteed ABE.
408 2019-08-14 Gary Dismukes <dismukes@adacore.com>
410 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
411 of an interface type, create an expression function (that
412 returns False) rather than declaring an abstract function.
413 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
414 False unconditionally at the start of the loop creating wrappers
415 for inherited operations.
417 2019-08-14 Bob Duff <duff@adacore.com>
419 * table.adb: Assert that the table is not locked when increasing
420 Last, even if it doesn't cause reallocation. In other words,
421 assert that on operations that MIGHT cause reallocation.
422 * table.ads: Fix comment accordingly.
424 2019-08-14 Arnaud Charlet <charlet@adacore.com>
426 * doc/gnat_ugn/gnat_and_program_execution.rst: Remove
427 documentation of gnatelim.
429 2019-08-14 Bob Duff <duff@adacore.com>
431 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
432 warning to the Sloc of the first pragma argument, rather than to
433 the pragma itself. This is to make pragmas processed after the
434 back end use the same Sloc as pragmas processed earlier, in the
435 front end. There's no reason for this discrepancy, and it
436 hinders further work on this ticket.
438 2019-08-14 Bob Duff <duff@adacore.com>
440 * sem.ads (Inside_A_Generic): Remove the ??? comment.

503 <Swap_Private_Dependents>: Do not rely solely on the
504 Is_Child_Unit flag on the unit to recurse.

506 function. Use it to recurse on the private dependent entities
509 2019-08-14 Javier Miranda <miranda@adacore.com>

516 * sem_util.adb (New_Copy_Tree, Visit_Entity): A quantified
517 expression includes the implicit declaration of the loop
518 parameter. When a quantified expression is copied during
519 expansion, for example when building the precondition code from
520 the generated pragma, a new loop parameter must be created for
521 the new tree, to prevent duplicate declarations for the same

1135 'Valid as a replacement for a range check on a discrete type
1136 when the bounds of the range are given by type conversions,
1137 because in such a case there are distinct types involved and the
1138 subbested attribute replacement would be misplaced.
1140 2019-07-22 Yannick Moy <moy@adacore.com>
1142 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,
1143 Is_Subpath_Expression): Add parameter Is_Traversal to adapt

1204 libgnat/s-valwch.ads: Change categorization of packages that
1205 implement attribute 'Value from Pure to Preelaborate, to prevent
1206 undesirable optimizations when the evaluation of the attribute
1207 raises Constraint_Error, but subsequent use of the result of
1208 this evsaluation is removed by a subsequent optimization.

1212 * sem_warn.adb (Check_References): Do not emit s warning on a

1225 Image_Enumeration_16, Image_Enumeration_32): Define the index of
1226 Index_Table with range Natural'First .. Names'Length since in
1227 the worst case all the literals of the enumeration type would be
1228 single letter literals and the Table built by the frontend would
1229 have as many components as the length of the names string. As a
1230 result of this enhancement, the internal tables declared using
1231 Index_Table have a length closer to the real needs, thus
1232 avoiding the declaration of large arrays on 32-bit CCG targets.
