3 * exp_attr.adb (Attribute_Valid): Correct the handling of
4 private types where the full type is modular. System.Address is
5 an example. Otherwise, we convert uncheckedly to a signed type,
6 so we get an incorrect range 0 .. -1, for which all values will
7 fail. The 'Valid attribute is illegal for such types, but we
8 generate such illegal attribute_references for 'Valid_Scalars,
9 and we generate 'Valid_Scalars when the -gnateV switch is used.
10 Rename Btyp --> PBtyp to avoid hiding the outer Btyp, which was
12 * libgnat/a-except.adb: Set the Exception_Raised component.
13 Otherwise, we have incorrect reads of invalid data.

57 * exp_atag.ads, exp_atag.adb (Build_Inherit_Predefined_Prims):
58 Adding formal to specify how many predefined primitives are
59 inherited from the parent type.
60 * exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
61 (Make_Secondary_DT): Compute the number of predefined primitives
62 of all tagged types (including tagged types not defined at
63 library level). Previously we unconditionally relied on the
64 Max_Predef_Prims constant value when building the dispatch
65 tables of tagged types not defined at library level (thus
66 consuming more memory for their dispatch tables than required).
67 (Make_DT): Compute the number of predefined primitives that must
68 be inherited from their parent type when building the dispatch
69 tables of tagged types not defined at library level. Previously
70 we unconditionally relied on the Max_Predef_Prims constant value
71 when building the dispatch tables of tagged types not defined at
72 library level (thus copying more data than required from the
75 2019-08-19 Bob Duff <duff@adacore.com>
77 * sem_ch13.adb (Record_Hole_Check): Procedure to check for holes
78 that incudes processing type extensions. A type extension is
79 processed by first calling Record_Hole_Check recursively on the
80 parent type to compute the bit number after the last component
83 2019-08-19 Gary Dismukes <dismukes@adacore.com>
85 * checks.adb (Length_Mismatch_Info_Message): New function in
86 Selected_Length_Checks to return a message indicating the
87 element counts for the mismatched lengths for a failed
88 compile-time length check.
89 (Plural_Or_Singular_Ending): Support function in
90 Length_Mismatch_Info_Message to return either "" or "s", for
91 concatenating to the end of words.
92 (Selected_Length_Checks): Pass the result of
93 Length_Mismatch_Info_Message as an extra warning message to
94 Compile_Time_Constraint_Error to indicate the mismatched lengths
95 for a failed compile-time length check.

97 message formal (Extra_Msg), defaulted to the empty string.
98 * sem_util.adb (Compile_Time_Constraint_Error): Output an extra
99 message following the main warning message (when Extra_Msg is
100 not the empty string).
102 2019-08-19 Patrick Bernardi <bernardi@adacore.com>
104 * socket.c: Removed the redefinition of getaddrinfo, getnameinfo
105 and freeaddrinfo to internal VxWorks kernel calls because they
106 are, well, internal kernel calls and cannot be called from RTPs.
107 VxWorks provides the necessary components to call these routines
110 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
112 * exp_dist.adb (Is_Generic_Actual_Subtype): New predicate.
113 (Build_From_Any_Call, Build_To_Any_Call, Build_TypeCode_Call):
114 Use it instead of Is_Generic_Actual_Type flag to detect subtypes
115 representing generic actual types.
117 2019-08-19 Ed Schonberg <schonberg@adacore.com>
119 * sem_warn.adb (Check_References, Generic_Body_Formal): When a
120 formal parameter of a generic subprogram is not referenced in
121 the body, place the corresponding warning on the corresponding
122 entity in the specification of the generic body, as is done for
123 non-generic subprograms.
125 2019-08-19 Bob Duff <duff@adacore.com>
127 * errout.ads (Size_Too_Small_Message): New constant.

150 parameter of the generic. Function used to decide whether a
151 function is a pledge function.
152 (Check_Not_Borrowed): Disable check inside the second parameter
153 of a pledge function for the path borrowed by the first
154 parameter. Also disable checks for entities inside a Global

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

201 2019-08-14 Joffrey Huguet <huguet@adacore.com>
203 * libgnat/a-cofuba.ads: Add a Length attribute to type
204 Container. Add a type Array_Base which replaces the previous
205 Elements attribute of Container.
206 (Content_Init): New subprogram. It is used to initialize the
207 Base attribute of Container.
208 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
209 resize the underlying array of a container if necessary.
210 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,
211 Union): Update to match changes in type declarations.
212 (Add): Modify body to damp the time and space cost in a specific
214 (Content_Init): New subprogram. It is used to initialize the
215 Base attribute of Container.
216 (Remove): Modify body to damp the time and space cost in a

230 in the comparison against the maximum number of instantiations.
232 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
234 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
235 in the comparison against the maximum number of instantiations.
237 2019-08-14 Ed Schonberg <schonberg@adacore.com>
239 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
240 involves a Ghost aspect it may have been replaced by a null
241 statement; use the original node to find next Rep_Item.
242 * repinfo.adb (List_Entities): Do not list an Ignored
243 Ghost_Entity, for which information may have been deleted.
245 2019-08-14 Bob Duff <duff@adacore.com>
247 * sem_prag.ads, sem_prag.adb
248 (Process_Compile_Time_Warning_Or_Error): In parameterless
249 version, improve detection of whether we are in a generic unit
250 to cover the case of an instance within a generic unit.
251 (Process_Compile_Time_Warning_Or_Error): Rename the
252 two-parameter version to be
253 Validate_Compile_Time_Warning_Or_Error, and do not export it.
254 Issue a warning if the condition is not known at compile time.
255 The key point is that the warning must be given only for pragmas
256 deferred to the back end, because the back end discovers
257 additional values that are known at compile time. Previous
258 changes in this ticket have enabled this by deferring to the
259 back end without checking for special cases such as 'Size.
260 (Validate_Compile_Time_Warning_Or_Error): Rename to be
261 Defer_Compile_Time_Warning_Error_To_BE.
262 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):
263 Add new switches -gnatw_c and -gnatw_C to control the above
265 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
266 Document new switches.

272 the shortcut based on Is_Inlined to the back-end inlining case.
274 2019-08-14 Bob Duff <duff@adacore.com>
276 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
277 protected functions to get rid of spurious error. The
278 transformation done by this procedure triggers legality errors
279 in the generated code in this case.
281 2019-08-14 Bob Duff <duff@adacore.com>
283 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
284 processing to the back end in all cases where the pragma's
285 condition is not known at compile time during the front end
286 (except in generics), as opposed to detecting 'Size attributes
287 and the like. This ensures that we take advantage of whatever
288 can be compile-time known after running the back end, as opposed
289 to having the front end guess what the back end can do. Remove
290 a little duplicated code at the call site.
291 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
292 Elists while in Validate_Compile_Time_Warning_Errors, because it
293 does analysis and name resolution, which sometimes involves

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

449 2019-08-14 Ed Schonberg <schonberg@adacore.com>
451 * sem_util.adb (New_Copy_Tree, Visit_Entity): A quantified
452 expression includes the implicit declaration of the loop
453 parameter. When a quantified expression is copied during
454 expansion, for example when building the precondition code from
455 the generated pragma, a new loop parameter must be created for
456 the new tree, to prevent duplicate declarations for the same

500 local variables and use them. When the derived type fully
501 constrains the parent type, rewrite it as a subtype of an
502 implicit (unconstrained) derived type instead of the other way

521 * sem_ch3.adb (Build_Underlying_Full_View): Delete.
522 (Complete_Private_Subtype): Do not set the full view on the

540 * sem_res.adb (Resolve_Selected_Component): When the type of the
541 component is an access to a class-wide type and the type of the
542 context is an access to a tagged type the relevant type is that
543 of the component (since in such case we may need to generate
544 implicit type conversions or dispatching calls).

548 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Preanalyze

1113 2019-07-22 Javier Miranda <miranda@adacore.com>
1115 * sem_res.adb (Resolve_Actuals): Replace code that displaces the

1138 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
1139 libgnat/s-valwch.ads: Change categorization of packages that
1140 implement attribute 'Value from Pure to Preelaborate, to prevent
1141 undesirable optimizations when the evaluation of the attribute
1142 raises Constraint_Error, but subsequent use of the result of
1143 this evsaluation is removed by a subsequent optimization.

1162 the worst case all the literals of the enumeration type would be
1163 single letter literals and the Table built by the frontend would
1164 have as many components as the length of the names string. As a
1165 result of this enhancement, the internal tables declared using
1166 Index_Table have a length closer to the real needs, thus
1167 avoiding the declaration of large arrays on 32-bit CCG targets.
