19 * libgnat/s-os_lib.ads, libgnat/s-os_lib.adb (To_Ada, To_C): New
22 2019-08-19 Bob Duff <duff@adacore.com>
24 * exp_attr.adb (Attribute_Valid): Correct the handling of
25 private types where the full type is modular. System.Address is
26 an example. Otherwise, we convert uncheckedly to a signed type,
27 so we get an incorrect range 0 .. -1, for which all values will
28 fail. The 'Valid attribute is illegal for such types, but we
29 generate such illegal attribute_references for 'Valid_Scalars,
30 and we generate 'Valid_Scalars when the -gnateV switch is used.
31 Rename Btyp --> PBtyp to avoid hiding the outer Btyp, which was
33 * libgnat/a-except.adb: Set the Exception_Raised component.
34 Otherwise, we have incorrect reads of invalid data.

79 Adding formal to specify how many predefined primitives are
80 inherited from the parent type.

82 (Make_Secondary_DT): Compute the number of predefined primitives
83 of all tagged types (including tagged types not defined at
84 library level). Previously we unconditionally relied on the
85 Max_Predef_Prims constant value when building the dispatch
86 tables of tagged types not defined at library level (thus
87 consuming more memory for their dispatch tables than required).
88 (Make_DT): Compute the number of predefined primitives that must
89 be inherited from their parent type when building the dispatch
90 tables of tagged types not defined at library level. Previously
91 we unconditionally relied on the Max_Predef_Prims constant value
92 when building the dispatch tables of tagged types not defined at
93 library level (thus copying more data than required from the
96 2019-08-19 Bob Duff <duff@adacore.com>
98 * sem_ch13.adb (Record_Hole_Check): Procedure to check for holes
99 that incudes processing type extensions. A type extension is
100 processed by first calling Record_Hole_Check recursively on the
101 parent type to compute the bit number after the last component
104 2019-08-19 Gary Dismukes <dismukes@adacore.com>
106 * checks.adb (Length_Mismatch_Info_Message): New function in
107 Selected_Length_Checks to return a message indicating the
108 element counts for the mismatched lengths for a failed
109 compile-time length check.
110 (Plural_Or_Singular_Ending): Support function in
111 Length_Mismatch_Info_Message to return either "" or "s", for
112 concatenating to the end of words.
113 (Selected_Length_Checks): Pass the result of
114 Length_Mismatch_Info_Message as an extra warning message to
115 Compile_Time_Constraint_Error to indicate the mismatched lengths
116 for a failed compile-time length check.

118 message formal (Extra_Msg), defaulted to the empty string.
119 * sem_util.adb (Compile_Time_Constraint_Error): Output an extra
120 message following the main warning message (when Extra_Msg is
121 not the empty string).
123 2019-08-19 Patrick Bernardi <bernardi@adacore.com>
125 * socket.c: Removed the redefinition of getaddrinfo, getnameinfo
126 and freeaddrinfo to internal VxWorks kernel calls because they
127 are, well, internal kernel calls and cannot be called from RTPs.
128 VxWorks provides the necessary components to call these routines
131 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
133 * exp_dist.adb (Is_Generic_Actual_Subtype): New predicate.
134 (Build_From_Any_Call, Build_To_Any_Call, Build_TypeCode_Call):
135 Use it instead of Is_Generic_Actual_Type flag to detect subtypes
136 representing generic actual types.
138 2019-08-19 Ed Schonberg <schonberg@adacore.com>
140 * sem_warn.adb (Check_References, Generic_Body_Formal): When a
141 formal parameter of a generic subprogram is not referenced in
142 the body, place the corresponding warning on the corresponding
143 entity in the specification of the generic body, as is done for
144 non-generic subprograms.
146 2019-08-19 Bob Duff <duff@adacore.com>

222 2019-08-14 Joffrey Huguet <huguet@adacore.com>
224 * libgnat/a-cofuba.ads: Add a Length attribute to type
225 Container. Add a type Array_Base which replaces the previous
226 Elements attribute of Container.
227 (Content_Init): New subprogram. It is used to initialize the
228 Base attribute of Container.
229 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
230 resize the underlying array of a container if necessary.
231 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,
232 Union): Update to match changes in type declarations.
233 (Add): Modify body to damp the time and space cost in a specific

251 in the comparison against the maximum number of instantiations.
253 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
255 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
256 in the comparison against the maximum number of instantiations.
258 2019-08-14 Ed Schonberg <schonberg@adacore.com>
260 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
261 involves a Ghost aspect it may have been replaced by a null
262 statement; use the original node to find next Rep_Item.
263 * repinfo.adb (List_Entities): Do not list an Ignored
264 Ghost_Entity, for which information may have been deleted.
266 2019-08-14 Bob Duff <duff@adacore.com>
268 * sem_prag.ads, sem_prag.adb
269 (Process_Compile_Time_Warning_Or_Error): In parameterless
270 version, improve detection of whether we are in a generic unit
271 to cover the case of an instance within a generic unit.
272 (Process_Compile_Time_Warning_Or_Error): Rename the
273 two-parameter version to be
274 Validate_Compile_Time_Warning_Or_Error, and do not export it.
275 Issue a warning if the condition is not known at compile time.
276 The key point is that the warning must be given only for pragmas
277 deferred to the back end, because the back end discovers
278 additional values that are known at compile time. Previous
279 changes in this ticket have enabled this by deferring to the
280 back end without checking for special cases such as 'Size.
281 (Validate_Compile_Time_Warning_Or_Error): Rename to be
282 Defer_Compile_Time_Warning_Error_To_BE.
283 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):
284 Add new switches -gnatw_c and -gnatw_C to control the above
286 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:

292 * sem_ch12.adb (Might_Inline_Subp): Rework comment and restrict
293 the shortcut based on Is_Inlined to the back-end inlining case.
295 2019-08-14 Bob Duff <duff@adacore.com>
297 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
298 protected functions to get rid of spurious error. The
299 transformation done by this procedure triggers legality errors
300 in the generated code in this case.
302 2019-08-14 Bob Duff <duff@adacore.com>
304 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
305 processing to the back end in all cases where the pragma's
306 condition is not known at compile time during the front end
307 (except in generics), as opposed to detecting 'Size attributes
308 and the like. This ensures that we take advantage of whatever
309 can be compile-time known after running the back end, as opposed
310 to having the front end guess what the back end can do. Remove
311 a little duplicated code at the call site.
312 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
313 Elists while in Validate_Compile_Time_Warning_Errors, because it
314 does analysis and name resolution, which sometimes involves
317 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

330 (Pending_Instantiations): ...here.
331 (Called_Pending_Instantiations): New table.
332 (Node_Table_Size): New constant.
333 (Node_Header_Num): New subtype.
334 (Node_Hash): New function.
335 (To_Pending_Instantiations): New hash table.
336 (Add_Inlined_Body): Bail out early for subprograms in the main
337 unit or subunit. Likewise if the Is_Called flag is set. If the
338 subprogram is an instance, invoke Add_Inlined_Instance. Call
339 Set_Is_Called earlier. If the subrogram is within an instance,
340 invoke Add_Inlined_Instance. Also deal with the case where the
341 call itself is within an instance.
342 (Add_Inlined_Instance): New procedure.
343 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
344 (Add_Pending_Instantiation): Move the defence against ludicruous
345 number of instantiations to here. When back-end inlining is
346 enabled, associate an instantiation with its index in table and
347 mark a few selected kinds of instantiations as always needed.
348 (Initialize): Set Backend_Instances to No_Elist.
349 (Instantiate_Body): New procedure doing the work extracted
351 (Instantiate_Bodies): ...here. When back-end inlining is
352 enabled, loop over Called_Pending_Instantiations instead of
353 Pending_Instantiations.
354 (Is_Nested): Minor tweak.
355 (List_Inlining_Info): Also list the contents of
357 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
358 is set and otherwise set it before returning true.
359 (Analyze_Package_Instantiation): Remove the defence against
360 ludicruous number of instantiations. Invoke
361 Remove_Dead_Instance instead of doing the removal manually if
362 there is a guaranteed ABE.
364 2019-08-14 Gary Dismukes <dismukes@adacore.com>
366 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
367 of an interface type, create an expression function (that
368 returns False) rather than declaring an abstract function.
369 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
370 False unconditionally at the start of the loop creating wrappers
371 for inherited operations.
373 2019-08-14 Bob Duff <duff@adacore.com>
375 * table.adb: Assert that the table is not locked when increasing
376 Last, even if it doesn't cause reallocation. In other words,
377 assert that on operations that MIGHT cause reallocation.
378 * table.ads: Fix comment accordingly.
380 2019-08-14 Arnaud Charlet <charlet@adacore.com>
382 * doc/gnat_ugn/gnat_and_program_execution.rst: Remove
383 documentation of gnatelim.
385 2019-08-14 Bob Duff <duff@adacore.com>
387 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
388 warning to the Sloc of the first pragma argument, rather than to
389 the pragma itself. This is to make pragmas processed after the
390 back end use the same Sloc as pragmas processed earlier, in the
391 front end. There's no reason for this discrepancy, and it
392 hinders further work on this ticket.
394 2019-08-14 Bob Duff <duff@adacore.com>
396 * sem.ads (Inside_A_Generic): Remove the ??? comment.
398 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

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

472 * sem_util.adb (New_Copy_Tree, Visit_Entity): A quantified
473 expression includes the implicit declaration of the loop
474 parameter. When a quantified expression is copied during
475 expansion, for example when building the precondition code from
476 the generated pragma, a new loop parameter must be created for
477 the new tree, to prevent duplicate declarations for the same

1094 subbested attribute replacement would be misplaced.
1096 2019-07-22 Yannick Moy <moy@adacore.com>
1098 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,
1099 Is_Subpath_Expression): Add parameter Is_Traversal to adapt

1130 2019-07-22 Eric Botcazou <ebotcazou@adacore.com>
1132 * sprint.ads: Fix pasto in comment.
1134 2019-07-22 Javier Miranda <miranda@adacore.com>
1136 * sem_res.adb (Resolve_Actuals): Replace code that displaces the

1138 dispatch table by a type conversion (which takes care of
1139 handling all cases).
1141 2019-07-22 Eric Botcazou <ebotcazou@adacore.com>
1143 * sprint.adb (Sprint_Node_Actual)

1159 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
1160 libgnat/s-valwch.ads: Change categorization of packages that
1161 implement attribute 'Value from Pure to Preelaborate, to prevent
1162 undesirable optimizations when the evaluation of the attribute
1163 raises Constraint_Error, but subsequent use of the result of
1164 this evsaluation is removed by a subsequent optimization.
1166 2019-07-22 Ed Schonberg <schonberg@adacore.com>
1168 * sem_warn.adb (Check_References): Do not emit s warning on a

1181 Image_Enumeration_16, Image_Enumeration_32): Define the index of
1182 Index_Table with range Natural'First .. Names'Length since in
1183 the worst case all the literals of the enumeration type would be
1184 single letter literals and the Table built by the frontend would
1185 have as many components as the length of the names string. As a
1186 result of this enhancement, the internal tables declared using
1187 Index_Table have a length closer to the real needs, thus
1188 avoiding the declaration of large arrays on 32-bit CCG targets.
