6 inherited from the parent type.
7 * exp_disp.adb (Number_Of_Predefined_Prims): New subprogram.
8 (Make_Secondary_DT): Compute the number of predefined primitives
9 of all tagged types (including tagged types not defined at
10 library level). Previously we unconditionally relied on the
11 Max_Predef_Prims constant value when building the dispatch
12 tables of tagged types not defined at library level (thus
13 consuming more memory for their dispatch tables than required).
14 (Make_DT): Compute the number of predefined primitives that must
15 be inherited from their parent type when building the dispatch
16 tables of tagged types not defined at library level. Previously
17 we unconditionally relied on the Max_Predef_Prims constant value
18 when building the dispatch tables of tagged types not defined at
19 library level (thus copying more data than required from the
22 2019-08-19 Bob Duff <duff@adacore.com>
24 * sem_ch13.adb (Record_Hole_Check): Procedure to check for holes
25 that incudes processing type extensions. A type extension is
26 processed by first calling Record_Hole_Check recursively on the
27 parent type to compute the bit number after the last component
30 2019-08-19 Gary Dismukes <dismukes@adacore.com>
32 * checks.adb (Length_Mismatch_Info_Message): New function in
33 Selected_Length_Checks to return a message indicating the
34 element counts for the mismatched lengths for a failed
35 compile-time length check.
36 (Plural_Or_Singular_Ending): Support function in
37 Length_Mismatch_Info_Message to return either "" or "s", for
38 concatenating to the end of words.
39 (Selected_Length_Checks): Pass the result of
40 Length_Mismatch_Info_Message as an extra warning message to
41 Compile_Time_Constraint_Error to indicate the mismatched lengths

44 message formal (Extra_Msg), defaulted to the empty string.
45 * sem_util.adb (Compile_Time_Constraint_Error): Output an extra
46 message following the main warning message (when Extra_Msg is
47 not the empty string).
49 2019-08-19 Patrick Bernardi <bernardi@adacore.com>
51 * socket.c: Removed the redefinition of getaddrinfo, getnameinfo
52 and freeaddrinfo to internal VxWorks kernel calls because they
53 are, well, internal kernel calls and cannot be called from RTPs.
54 VxWorks provides the necessary components to call these routines
57 2019-08-19 Eric Botcazou <ebotcazou@adacore.com>
59 * exp_dist.adb (Is_Generic_Actual_Subtype): New predicate.
60 (Build_From_Any_Call, Build_To_Any_Call, Build_TypeCode_Call):
61 Use it instead of Is_Generic_Actual_Type flag to detect subtypes
62 representing generic actual types.
64 2019-08-19 Ed Schonberg <schonberg@adacore.com>
66 * sem_warn.adb (Check_References, Generic_Body_Formal): When a
67 formal parameter of a generic subprogram is not referenced in
68 the body, place the corresponding warning on the corresponding
69 entity in the specification of the generic body, as is done for
70 non-generic subprograms.
72 2019-08-19 Bob Duff <duff@adacore.com>
74 * errout.ads (Size_Too_Small_Message): New constant.

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

144 * gcc-interface/lang.opt (fdump-scos): Define.
145 * gcc-interface/misc.c (gnat_handle_option): Handle
148 2019-08-14 Joffrey Huguet <huguet@adacore.com>
150 * libgnat/a-cofuba.ads: Add a Length attribute to type
151 Container. Add a type Array_Base which replaces the previous
152 Elements attribute of Container.
153 (Content_Init): New subprogram. It is used to initialize the
154 Base attribute of Container.
155 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
156 resize the underlying array of a container if necessary.
157 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,
158 Union): Update to match changes in type declarations.
159 (Add): Modify body to damp the time and space cost in a specific

162 Base attribute of Container.
163 (Remove): Modify body to damp the time and space cost in a
166 2019-08-14 Bob Duff <duff@adacore.com>
168 * sem_ch13.adb (Get_Alignment_Value): Return 1 for Alignment 0,
169 and do not give an error.

177 in the comparison against the maximum number of instantiations.
179 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
181 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
182 in the comparison against the maximum number of instantiations.
184 2019-08-14 Ed Schonberg <schonberg@adacore.com>
186 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
187 involves a Ghost aspect it may have been replaced by a null
188 statement; use the original node to find next Rep_Item.
189 * repinfo.adb (List_Entities): Do not list an Ignored
190 Ghost_Entity, for which information may have been deleted.
192 2019-08-14 Bob Duff <duff@adacore.com>
194 * sem_prag.ads, sem_prag.adb
195 (Process_Compile_Time_Warning_Or_Error): In parameterless
196 version, improve detection of whether we are in a generic unit
197 to cover the case of an instance within a generic unit.
198 (Process_Compile_Time_Warning_Or_Error): Rename the
199 two-parameter version to be
200 Validate_Compile_Time_Warning_Or_Error, and do not export it.
201 Issue a warning if the condition is not known at compile time.
202 The key point is that the warning must be given only for pragmas
203 deferred to the back end, because the back end discovers
204 additional values that are known at compile time. Previous
205 changes in this ticket have enabled this by deferring to the
206 back end without checking for special cases such as 'Size.
207 (Validate_Compile_Time_Warning_Or_Error): Rename to be
208 Defer_Compile_Time_Warning_Error_To_BE.
209 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):

219 the shortcut based on Is_Inlined to the back-end inlining case.
221 2019-08-14 Bob Duff <duff@adacore.com>
223 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
224 protected functions to get rid of spurious error. The
225 transformation done by this procedure triggers legality errors
226 in the generated code in this case.
228 2019-08-14 Bob Duff <duff@adacore.com>
230 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
231 processing to the back end in all cases where the pragma's
232 condition is not known at compile time during the front end
233 (except in generics), as opposed to detecting 'Size attributes
234 and the like. This ensures that we take advantage of whatever
235 can be compile-time known after running the back end, as opposed
236 to having the front end guess what the back end can do. Remove
237 a little duplicated code at the call site.
238 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
239 Elists while in Validate_Compile_Time_Warning_Errors, because it
240 does analysis and name resolution, which sometimes involves
243 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

257 (Called_Pending_Instantiations): New table.
258 (Node_Table_Size): New constant.
259 (Node_Header_Num): New subtype.
260 (Node_Hash): New function.
261 (To_Pending_Instantiations): New hash table.
262 (Add_Inlined_Body): Bail out early for subprograms in the main
263 unit or subunit. Likewise if the Is_Called flag is set. If the
264 subprogram is an instance, invoke Add_Inlined_Instance. Call
265 Set_Is_Called earlier. If the subrogram is within an instance,
266 invoke Add_Inlined_Instance. Also deal with the case where the
267 call itself is within an instance.
268 (Add_Inlined_Instance): New procedure.
269 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
270 (Add_Pending_Instantiation): Move the defence against ludicruous
271 number of instantiations to here. When back-end inlining is
272 enabled, associate an instantiation with its index in table and
273 mark a few selected kinds of instantiations as always needed.
274 (Initialize): Set Backend_Instances to No_Elist.
275 (Instantiate_Body): New procedure doing the work extracted
277 (Instantiate_Bodies): ...here. When back-end inlining is
278 enabled, loop over Called_Pending_Instantiations instead of
279 Pending_Instantiations.
280 (Is_Nested): Minor tweak.
281 (List_Inlining_Info): Also list the contents of
283 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
284 is set and otherwise set it before returning true.
285 (Analyze_Package_Instantiation): Remove the defence against
286 ludicruous number of instantiations. Invoke
287 Remove_Dead_Instance instead of doing the removal manually if
288 there is a guaranteed ABE.
290 2019-08-14 Gary Dismukes <dismukes@adacore.com>
292 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
293 of an interface type, create an expression function (that
294 returns False) rather than declaring an abstract function.
295 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
296 False unconditionally at the start of the loop creating wrappers
297 for inherited operations.
299 2019-08-14 Bob Duff <duff@adacore.com>
301 * table.adb: Assert that the table is not locked when increasing
302 Last, even if it doesn't cause reallocation. In other words,
303 assert that on operations that MIGHT cause reallocation.
304 * table.ads: Fix comment accordingly.
306 2019-08-14 Arnaud Charlet <charlet@adacore.com>
308 * doc/gnat_ugn/gnat_and_program_execution.rst: Remove
309 documentation of gnatelim.
311 2019-08-14 Bob Duff <duff@adacore.com>
313 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
314 warning to the Sloc of the first pragma argument, rather than to
315 the pragma itself. This is to make pragmas processed after the
316 back end use the same Sloc as pragmas processed earlier, in the
317 front end. There's no reason for this discrepancy, and it
318 hinders further work on this ticket.
320 2019-08-14 Bob Duff <duff@adacore.com>
322 * sem.ads (Inside_A_Generic): Remove the ??? comment.
324 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
326 * inline.ads (Pending_Descriptor): Delete.

394 arrays with bounds not known at compile time.
396 2019-08-14 Ed Schonberg <schonberg@adacore.com>
398 * sem_util.adb (New_Copy_Tree, Visit_Entity): A quantified
399 expression includes the implicit declaration of the loop
400 parameter. When a quantified expression is copied during
401 expansion, for example when building the precondition code from
402 the generated pragma, a new loop parameter must be created for
403 the new tree, to prevent duplicate declarations for the same

487 * sem_res.adb (Resolve_Selected_Component): When the type of the
488 component is an access to a class-wide type and the type of the
489 context is an access to a tagged type the relevant type is that
490 of the component (since in such case we may need to generate
491 implicit type conversions or dispatching calls).

495 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Preanalyze
496 expression, rather do a full analysis, to prevent unwanted
