34 scalar type with a validity test when the membership appears in a
35 predicate expression, to prevent a spurious error when predicate is

53 designate an object (e.g. a function call).
55 2017-12-15 Ed Schonberg <schonberg@adacore.com>
57 * sem_ch6.adb (Conformking_Types): Two incomplete types are conforming
58 when one of them is used as a generic actual, but only within an

62 2017-12-15 Justin Squirek <squirek@adacore.com>
64 * sem_attr.adb (Resolve_Attribute): Modify check for aliased view on
65 prefix to use the prefix's original node to avoid looking at expanded
66 conversions for certain array types.
68 2017-12-15 Ed Schonberg <schonberg@adacore.com>
70 * sem_res.adb (Resolve_Membership_Op): Add warning on a membership
71 operation on a scalar type for which there is a user-defined equality

87 * types.ads, types.h, libgnat/a-except.adb, exp_ch11.adb
88 (PE_Build_In_Place_Mismatch): New reason code for raising when the

90 bug causes a mismatch of build-in-place between caller and callee.
91 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
92 PE_Build_In_Place_Mismatch.

141 concurrent type are now recorded regardless of the SPARK mode.
142 * sem_util.adb (Check_Part_Of_Reference): Split some of the tests in
143 individual predicates. A Part_Of reference is legal when it appears
144 within the statement list of the object's immediately enclosing

167 is available (Is_Verifiable_DIC_Pragma): Moved from Sem_Util.
168 * sem_util.adb (Has_Full_Default_Initialization):
169 Has_Fully_Default_Initializing_DIC_Pragma is now used to determine
170 whether a type has full default initialization due to pragma
171 Default_Initial_Condition.
172 (Has_Fully_Default_Initializing_DIC_Pragma): New routine.
173 (Is_Verifiable_DIC_Pragma): Moved to Exp_Util.
174 * sem_util.ads (Has_Fully_Default_Initializing_DIC_Pragma): New
176 (Is_Verifiable_DIC_Pragma): Moved to Exp_Util.
177 * sem_warn.adb (Is_OK_Fully_Initialized):
178 Has_Fully_Default_Initializing_DIC_Pragma is now used to determine
179 whether a type has full default initialization due to pragma
180 Default_Initial_Condition.
182 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
184 * sem_prag.adb (Match_Constituent): Do not quietly accept constants as

191 an array aggregate in an allocator, when the designated type is
192 unconstrained and the upper bound of the aggregate belongs to the base
195 2017-12-15 Bob Duff <duff@adacore.com>
197 * exp_ch6.adb (Expand_N_Extended_Return_Statement,
198 Expand_Simple_Function_Return): Assert that the b-i-p-ness of the
199 caller and callee match. Otherwise, we would need some substantial
200 changes to allow b-i-p calls non-b-i-p, and vice versa.
202 2017-12-15 Ed Schonberg <schonberg@adacore.com>
204 * exp_unst.adb (Unnest_Subprograms): Nothing to do if the main unit is
205 a generic package body. Unnesting is only an issue when generating
206 code, and if the main unit is generic then nested instance bodies have
207 not been created and analyzed, and unnesting will crash in the absence
210 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
212 * inline.adb (Add_Inlined_Body): Do not add a function which is
213 completed by an expression function defined in the same context as the
214 initial declaration because the completing body is not in a package
216 (Is_Non_Loading_Expression_Function): New routine.
218 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
220 * debug.adb: Move the functionality of -gnatdL to -gnatd_i. Restore
221 the behavior of -gnatdL from before revision 255412.
222 * sem_elab.adb: Update the section of compiler switches.
223 (Build_Call_Marker): Do not create a marker for a call which originates
224 from an expanded spec or body of an instantiated gener, does not invoke
225 a generic formal subprogram, the target is external to the instance,
226 and -gnatdL is in effect.
227 (In_External_Context): New routine.
228 (Process_Conditional_ABE_Activation_Impl): Update the uses of -gnatdL
230 (Process_Conditional_ABE_Call): Update the uses of -gnatdL and
232 * switch-c.adb (Scan_Front_End_Switches): Switch -gnatJ now sets switch
234 * exp_unst.adb: Minor typo fixes and edits.
236 2017-12-15 Ed Schonberg <schonberg@adacore.com>
238 * sem_ch6.adb (Possible_Freeze): Do not set Delayed_Freeze on an
239 subprogram instantiation, now that the enclosing wrapper package
240 carries an explicit freeze node. THis prevents freeze nodes for the
241 subprogram for appearing in the wrong scope. This is relevant when the
242 generic subprogram has a private or incomplete formal type and the
243 instance appears within a package that declares the actual type for the
244 instantiation, and that type has itself a delayed freeze.
246 2017-12-15 Patrick Bernardi <bernardi@adacore.com>
248 * doc/gnat_ugn/gnat_and_program_execution.rst: Removed references to
249 the environment variable GNAT_STACK_LIMIT from the Stack Overflow
250 Checking section as it is no longer used by any of our supported
253 2017-12-15 Bob Duff <duff@adacore.com>
255 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
256 Init_Assignment is rewritten, we need to set Assignment_OK on the new
257 node. Otherwise, we will get spurious errors when initializing via
258 assignment statement.
260 2017-12-15 Arnaud Charlet <charlet@adacore.com>
262 * exp_unst.adb (Visit_Node): Refine handling of 'Access to ignore non

266 2017-12-15 Eric Botcazou <ebotcazou@adacore.com>
268 * exp_attr.adb (Is_Inline_Floating_Point_Attribute): Fix comment.
269 * libgnat/s-fatgen.adb (Model): Use Machine attribute.
270 (Truncation): Likewise.
272 2017-12-15 Bob Duff <duff@adacore.com>
274 * exp_ch7.adb (Expand_Cleanup_Actions): Make sure the block and handled
275 statement sequence generated for certain extended return statements
276 have a Sloc that is not No_Location. Otherwise, the back end doesn't
277 set any location and ends up reading uninitialized variables.
279 2017-12-15 Bob Duff <duff@adacore.com>
281 * types.ads, exp_ch6.adb, libgnat/s-regexp.ads, opt.ads: Partly revert
282 r255414, committed by mistake.
284 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
286 * gcc-interface/Makefile.in: Generalize support for symbolic traces.

290 * gcc-interface/misc.c (default_pass_by_ref): Minor tweak.
292 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
294 * gcc-interface/trans.c (Call_to_gnu): Set DECL_DISREGARD_INLINE_LIMITS
295 to 0 on the callee if the call is recursive.
297 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
299 * gcc-interface/decl.c (gnat_to_gnu_field): Do not set the alignment
300 of the enclosing record type if it is not already set.
302 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
304 * gcc-interface/gigi.h (pad_type_has_rm_size): Declare.
305 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Do not build
306 a padding type for the alignment before validating the size.
307 Flip conditional construct and add a comment.
308 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Size>: Make sure to
309 apply the exception for padded objects to the type of the object.
310 * gcc-interface/utils.c (hash_pad_type): New static function.
311 (lookup_and_insert_pad_type): Rename into...
312 (canonicalize_pad_type): ...this. Call hash_pad_type, do only one
313 lookup with insertion and always return the canonical type.
314 (maybe_pad_type): Adjust to above changes. Set debug type later.
315 (pad_type_has_rm_size): New predicate.
316 (set_reverse_storage_order_on_pad_type): Adjust to above changes.
318 2017-12-13 Eric Botcazou <ebotcazou@adacore.com>

329 * gcc-interface/decl.c (gnat_to_gnu_entity): Robustify test for types
330 descendant of System.Address.
331 (gnat_to_gnu_subprog_type): Likewise.
333 2017-12-08 Jakub Jelinek <jakub@redhat.com>
335 * gcc-interface/utils.c (gnat_internal_attribute_table): Add
336 exclusions to the comment.
338 2017-12-07 Martin Sebor <msebor@redhat.com>
341 * gcc-interface/utils.c (gnat_internal_attribute_table): Initialize
342 new member of struct attribute_spec.
344 2017-12-06 Simon Wright <simon@pushface.org>

348 set, generate a null body.
350 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
352 * sem_util.adb (Contains_Refined_State): Remove.
354 2017-12-05 Ed Schonberg <schonberg@adacore.com>
356 * sem_ch13.adb (Analyze_Aspect_Specifications, case Predicate): A
357 predicate cannot apply to a formal type.

361 * exp_unst.ads: Fix typos.
363 2017-12-05 Jerome Lambourg <lambourg@adacore.com>
365 * libgnarl/s-taprop__qnx.adb: Better detect priority ceiling bug in
366 QNX. At startup, the first mutex created has a non-zero ceiling
367 priority whatever its actual policy. This makes some tests fail
368 (c940013 for example).
370 2017-12-05 Bob Duff <duff@adacore.com>
372 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Call
373 Expand_Cleanup_Actions for N_Extended_Return_Statement.
374 * exp_ch7.adb (Expand_Cleanup_Actions): Handle
375 N_Extended_Return_Statement by transforming the statements into a
376 block, and (indirectly) calling Expand_Cleanup_Actions on the block.
377 It's too hard for Expand_Cleanup_Actions to operate directly on the
378 N_Extended_Return_Statement, because it has a different structure than
379 the other node kinds that Expand_Cleanup_Actions.
380 * exp_util.adb (Requires_Cleanup_Actions): Add support for
381 N_Extended_Return_Statement. Change "when others => return False;" to
382 "when others => raise ...;" so it's clear what nodes this function
383 handles. Use named notation where appropriate.
384 * exp_util.ads: Mark incorrect comment with ???.
386 2017-12-05 Javier Miranda <miranda@adacore.com>
388 * exp_ch9.adb (Install_Private_Data_Declarations): Add missing
389 Debug_Info_Needed decoration of internally generated discriminal
390 renaming declaration.
392 2017-12-05 Arnaud Charlet <charlet@adacore.com>
394 * exp_unst.adb (Unnest_Subprogram): Add handling of 'Access on

404 * sem_util.adb (Contains_Refined_State): Remove.
406 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
408 * rtsfind.ads: Add new enumeration literals: RE_Clock_Time (for
409 Ada.Real_Time.Clock_Time) and RO_CA_Clock_Time (for
410 Ada.Calendar.Clock_Time).
412 2017-12-05 Ed Schonberg <schonberg@adacore.com>
414 * sem_ch4.adb (Is_Private_Overriding): If the candidate private
415 subprogram is overloaded, scan the list of homonyms in the same
416 scope, to find the inherited operation that may be overridden
418 * exp_ch11.adb, exp_ch7.adb: Minor reformatting.
420 2017-12-05 Bob Duff <duff@adacore.com>
422 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
423 Init_Assignment is rewritten, we need to set Assignment_OK on the new
424 node. Otherwise, we will get spurious errors when initializing via
425 assignment statement.
427 2017-12-05 Hristian Kirtchev <kirtchev@adacore.com>
429 * sem_elab.adb: Update the terminology and switch sections.
430 (Check_SPARK_Model_In_Effect): New routine.
431 (Check_SPARK_Scenario): Verify the model in effect for SPARK.
432 (Process_Conditional_ABE_Call_SPARK): Verify the model in effect for

436 (Process_Conditional_ABE_Variable_Assignment_SPARK): Verify the model
439 2017-12-05 Nicolas Setton <setton@adacore.com>
441 * terminals.c (__gnat_setup_child_communication): As documented,
442 __gnat_setup_child_communication should not terminate - it is intended
443 to be used as the child process of a call to fork(). However, execvp
444 might actually return in some cases, for instance when attempting to
445 run a 32-bit binary on a 64-bit Linux distribution when the
446 compatibility packages are not installed. In these cases, exit the
447 program to conform to the documentation.
449 2017-12-05 Olivier Hainque <hainque@adacore.com>

520 Update the documentation on elaboration-related compilation
521 switches. Update the documentation on adding a new target. Add
522 Processing_Attributes which represent the state of the Processing
523 phase. Resurrect the previous elaboration model as "legacy elaboration
525 (Build_Call_Marker): This routine does not function when the legacy
526 elaboration model is in effect. Do not consider entry calls and requeue
527 statements when debug flag d_e is in effect. Do not consider calls to
528 subprograms which verify the runtime semantics of certain assertion
529 pragmas when debug flag d_p is in effect.
530 (Build_Variable_Reference_Marker): This routine does not function when
531 the legacy elaboration model is in effect.
532 (Check_Elaboration_Scenarios): This routine does not function when the
533 legacy elaboration model is in effect.
534 (Ensure_Prior_Elaboration): The various flags have now been replaced
535 with a state. Do not generate implicit Elaborate[_All] pragmas when
536 their creation has been suppressed.
537 (Ensure_Prior_Elaboration_Static): The with clause is marked based on
538 the requested pragma, not on the nature of the scenario.
539 (In_External_Context): Removed.
540 (Is_Assertion_Pragma_Target): New routine.

1174 2017-11-09 Pascal Obry <obry@adacore.com>
1176 * libgnarl/s-taprop__mingw.adb: On Windows, initialize the thead handle
1177 only for foreign threads. We initialize the thread handle only if not
1178 yet initialized. This happens in Enter_Task for foreign threads only.
1179 But for native threads (Ada tasking) we do want to keep the real
1180 handle (from Create_Task) to be able to free the corresponding
1181 resources in Finalize_TCB (CloseHandle).
1183 2017-11-09 Yannick Moy <moy@adacore.com>

1194 dispatch table is statically built.
1195 (Make_DT): Declare constant the Interface_Table object associated with
1196 an statically built dispatch table. For this purpose the Offset_To_Top

1199 the Offset_To_Top field of secondary dispatch tables when the dispatch
1200 table is statically built.

1210 to avoid a dormant bug.
1212 2017-11-09 Jerome Lambourg <lambourg@adacore.com>
1214 * init.c: Define missing __gnat_alternate_stack for QNX. Set it to 0,
1215 as such capability is not available on the OS.
1216 * link.c: Make sure linker options for QNX are correct.
1217 * libgnarl/s-osinte__qnx.ads: Add some missing bindings to pthread.
1218 * libgnarl/s-taprop__qnx.adb: New, derived from s-taprop__posix.adb. This brings
1219 in particular a workaround with locks priority ceiling where a higher
1220 priority task is allowed to lock a lower ceiling priority lock. This
1221 also fixes the scheduling of FIFO tasks when the priority of a task is
1223 * libgnat/system-qnx-aarch64.ads: Fix priority ranges.
1225 2017-11-09 Yannick Moy <moy@adacore.com>
1227 * erroutc.adb (Output_Error_Msgs): Justify CodePeer false positive
1229 * gnatbind.adb (Scan_Bind_Arg): Simplify test to remove always true
1231 * namet.adb (Copy_One_Character): Add assumption for static analysis,
1232 as knowledge that Hex(2) is in the range 0..255 is too complex for
1234 (Finalize): Add assumption for static analysis, as the fact that there
1235 are symbols in the table depends on a global invariant at this point in
1237 * set_targ.adb (Check_Spaces): Justify CodePeer false positive message.
1238 * stylesw.adb (Save_Style_Check_Options): Rewrite to avoid test always
1241 2017-11-09 Javier Miranda <miranda@adacore.com>
1243 * libgnat/s-rident.ads (Static_Dispatch_Tables): New restriction name.
1244 * exp_disp.adb (Building_Static_DT): Check restriction.
1245 (Building_Static_Secondary_DT): Check restriction.
1246 (Make_DT): Initialize the HT_Link to No_Tag.
1247 * opt.ads (Static_Dispatch_Tables): Rename flag...

1281 * exp_util.adb (Find_Interface_Tag): Default initialize AI_Tag.
1282 * freeze.adb (Check_Component_Storage_Order): Default initialize
1283 Comp_Byte_Aligned rather than silencing messages with pragma
1284 Warnings(Off), which does not work for CodePeer initialization
1285 messages, and given that here the possible read of an unitialized value
1286 depends on a proper use of parameters by the caller.
1287 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.
1288 * sem_ch12.adb (Build_Operator_Wrapper): Default initialize Expr.
1289 * sem_ch3.adb (Build_Derived_Array_Type): Default initialize

1292 pragma Warnings(Off).
1293 (Analyze_Case_Expression): Rescope checking block within branch where
1294 Others_Present is set by the call to Check_Choices.
1295 * sem_ch5.adb (Analyze_Assignment): Default initialize
1297 * sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,
1298 and restructure code to defend against previous errors, so that, in
1299 that case, control does not flow to the elsif condition which read an
1300 uninitialized Obj_Decl.
1301 * sem_ch9.adb (Analyze_Requeue): Default initialize Synch_Type.
1302 (Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
1303 which seem to be left uninitialized and possibly read in some cases.
1304 * sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more
1305 precisely. This requires to exchange the test for exiting in case of
1306 too many positions and the increment to Position, inside the loop.
1307 * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,
1308 which cannot be read uninitialized, but the reasons for that are quite
1310 * sem_intr.adb (Check_Intrinsic_Call): Default initialize Rtyp.
1311 * sem_prag.adb (Collect_Subprogram_Inputs_Outputs): Default initialize
1313 * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
1314 and test for presence of non-null Opnd_Type before testing its scope,
1315 in a test which would read its value uninitialized, and is very rarely
1316 exercized (it depends on the presence of an extension of System).
1317 * sem_spark.ads: Update comment to fix name of main analysis procedure.
1318 * sem_warn.adb (Warn_On_Known_Condition): Default initialize
1320 * set_targ.adb (FailN): Mark procedure with No_Return.
1321 * stylesw.adb (Save_Style_Check_Options): Delete useless code to
1322 initialize all array Options to white space, as there is already code
1323 doing the same for the remaining positions in Options at the end of the
1326 2017-11-09 Eric Botcazou <ebotcazou@adacore.com>
1328 * exp_ch11.adb (Possible_Local_Raise): Do not issue the warning for

1333 * sem_prag.adb (Analyze_Part_Of): Reword error message.

1340 * sem_ch4.adb (Analyze_Call): Reject a call to a function that returns
1341 a limited view of a type T declared in unit U1, when the function is
1342 declared in another unit U2 and the call appears in a procedure within

1347 * sem_ch8.adb (Analyze_Use_Package): Force installation of use_clauses
1348 when processing generic instances.
1350 2017-11-09 Bob Duff <duff@adacore.com>
1352 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
1353 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
1354 objects can have those special values. Valid_Name_Id could usefully be
1355 used all over the compiler front end, but that's too much trouble for
1356 now. If we did that, we might want to rename:
1357 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
1358 For parameters of type Valid_Name_Id, remove some redundant tests,
1359 including the ones found by CodePeer. Use Is_Valid_Name instead of
1360 membership test when appropriate.
1361 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
1362 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
1363 "in Error_Name_Or_No_Name".
1364 (Check_Parameterless_Call): Use "not Is_Valid_Name" instead of "in
1365 Error_Name_Or_No_Name".

1370 mode here unless -gnateC is specified.

1376 * lib-writ.adb (Write_ALI): Remove processing of the frontend xrefs as
1377 part of the ALI writing; they are now processed directly from memory

1425 * sem_res.adb (Resolve): If expression is an entity whose type has
1426 implicit dereference, generate reference to it, because no reference is
1427 generated for an overloaded entity during analysis, given that its
1428 identity may not be known.
1430 2017-11-09 Javier Miranda <miranda@adacore.com>

1439 Set_Static_Offset_To_Top passing a negative offet-to-top value;
1440 initialize also the offset-to-top field with a negative offset.
1441 * libgnat/a-tags.adb (Base_Address): Displace the pointer by means of
1442 an addition since the offset-to-top field is now a negative value.
1443 (Displace): Displace the pointer to the object means of a substraction
1444 since it is now a negative value.
1445 (Set_Dynamic_Offset_to_top): Displace the pointer to the object by

2760 statement of an expression function, return the level of the function.
2761 This is relevant when the object involves an implicit conversion

2789 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking

2793 as for the other Is_B-I-P... functions.

2801 internally-generated call.

2806 implies >= Ada 2005.

2836 a freeze node for the instance of the parent if it appears in the same
2837 scope and is not frozen yet.

2844 2017-10-09 Bob Duff <duff@adacore.com>
2846 * exp_ch3.adb (Build_Assignment): Parameter name N was somewhat
2847 confusing. Same for N_Loc. Remove assumption that b-i-p implies
2848 limited. This is for the case of a function call that occurs as the
2849 default for a record component.
2850 (Expand_N_Object_Declaration): Deal with the case where expansion has
2851 created an object declaration initialized with something like

2859 object itself must be retrieved when generating the range test that
2860 implements the validity check on a scalar type.

2921 (Is_Build_In_Place_Result_Type): New function to accompany
2922 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
2923 sometimes we just have the type on our hands, not the function. For
2924 now, does the same thing as the old version, so build-in-place is
2925 disabled for nonlimited types, except that you can use -gnatd.9 to
2927 * exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
2928 accompany Is_Build_In_Place_Function and

3982 * s-htable.adb: Fix typo.
3984 2017-09-08 Bob Duff <duff@adacore.com>
3986 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
3988 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3990 * sem_aggr.adb: minor style fix.

4005 2017-09-08 Bob Duff <duff@adacore.com>
4007 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
4008 Ada_2020, along the same lines as the other Ada version pragmas.
4010 2017-09-08 Gary Dismukes <dismukes@adacore.com>
4012 * sem_ch12.adb: Minor typo fixes and reformatting.
4014 2017-09-08 Yannick Moy <moy@adacore.com>
4016 * sem_aggr.adb (Resolve_Record_Aggregate):
4017 Rewrite bounds of aggregate subexpressions which may depend on
4018 discriminants of the enclosing aggregate.
4020 2017-09-08 Yannick Moy <moy@adacore.com>
4022 * sem_ch5.adb: Prevent assertion failure on illegal code.
4024 2017-09-08 Yannick Moy <moy@adacore.com>
4026 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
4027 calling Renamed_Entity on an entity which cannot be a renaming.
4029 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4031 * exp_aggr.adb: Add with & use clause for Urealp.
4032 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
4033 elementary types instead of just discrete types.
4034 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
4035 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
4036 Be prepared for the FP zero value in the memset case. Add small
4039 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4041 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
4044 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4046 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
4047 of New_Copy because the latter leaves the syntactic structure of
4048 the tree inconsistent (a child is accessible through two parents)
4049 and prevents proper replication of itypes by subsequent calls
4051 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
4052 New_Copy because the latter leaves the syntactic structure of the
4053 tree inconsistent (a child is accessible through two parents)
4054 and prevents proper replication of itypes by subsequent calls
4056 * sem_util.adb (In_Subtree): New routine.
4057 (New_Copy_Tree): Reimplemented.
4058 * sem_util.ads (In_Subtree): New routine.

4063 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
4064 for aspect Default_Value is a static scalar value, but it does
4065 not freeze the type. Yhis allows for subsequent representation
4066 clauses for the type.
4068 2017-09-08 Javier Miranda <miranda@adacore.com>
4070 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
4071 not add entries into the undefined reference table when we are
4072 compiling with errors ignored.
4074 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4076 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
4077 check if the instance is within an enclosing instance body. The
4078 formal package was legal in the enclosing generic, and is
4079 legal in the enclosing instantiation. This optimisation may be
4080 applicable elsewhere, and it also removes spurious errors that
4081 may arise with on-the-fly processing of instantiations that
4082 contain Inline_Always subprograms.
4084 2017-09-08 Vincent Celier <celier@adacore.com>
4086 * gnatcmd.adb: Disregard empty argument of GNAT driver.
4088 2017-09-08 Justin Squirek <squirek@adacore.com>
4090 * checks.adb (Insert_Valid_Check): Manually decorate
4091 the generated temporary for range valdity checks.
4093 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4095 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
4097 2017-09-08 Justin Squirek <squirek@adacore.com>
4099 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
4100 case to handle underscore flags.
4101 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
4102 new procedure to handle underscores.
4104 2017-09-08 Javier Miranda <miranda@adacore.com>
4106 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
4107 divisions with fixed point results to avoid generating twice
4108 the runtime check on divide by zero.
4109 * checks.adb (Apply_Divide_Checks): Ensure that operands are
4110 not evaluated twice (once for their runtime checks and once for
4111 their regular computation).
4113 2017-09-08 Yannick Moy <moy@adacore.com>
4115 * sem_prag.adb (Analyze_Part_Of): Add missing
4116 return statements after issuing errors. Add detection of
4117 out-of-order item and single concurrent type.

4247 when the actual is a construct that involves a dereference of an
4248 expression that includes a formal of the enclosing subprogram,
4249 In such cases, the accessibility level of the actual is that of
4250 the corresponding formal, which is passed in as an additional

4261 exceptions instead of crashes. Check for absurdly long strings
4262 and empty strings. Empty strings cause trouble because they can
4263 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
4264 be empty, which causes an array index out of bounds.

4414 (Make_Build_In_Place_Call_In_Object_Declaration): Move the code
4415 that replaces the internal name of the renaming declaration
4416 into the new subprogram Replace_Renaming_Declaration_Id.

4442 access to interface types. Remove also the accessibility check.
4444 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4446 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
4447 all the types that are referenced by the expression.
4448 (Analyze_Expression_Function): Call Freeze_Expr_Types for
4449 a completion instead of manually freezing the type of the
4451 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
4453 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4455 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
4456 New procedure, auxiliary to Expand_Pragma_Check, to handle
4457 references to the discriminants of a protected type within a
4458 precondition of a protected operation. This is needed because
4459 the original precondition has been analyzed in the context of
4460 the protected declaration, but in the body of the operation
4461 references to the discriminants have been replaved by references
4462 to the discriminants of the target object, and these references
4463 are only created when expanding the protected body.
4465 2017-09-08 Yannick Moy <moy@adacore.com>
4467 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
4470 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4472 * exp_attr.adb (Build_Record_VS_Func): If the record is an
4473 unchecked union, do not emit checks for its (non-existent)
4474 discriminants, or for variant parts that depend on them.
4476 2017-09-08 Justin Squirek <squirek@adacore.com>
4478 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
4479 Find_Comparison_Type.Try_One_Interp): Add check for generic
4482 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4484 * sem_ch3.adb, layout.adb, layout.ads, exp_attr.adb, debug.adb,
4485 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
4486 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
4487 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
4488 remaining references to AAMP_On_Target.
4490 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4492 * style.adb: Fix typo.
4494 2017-09-08 Javier Miranda <miranda@adacore.com>
4496 * einfo.adb (Underlying_Type): Add missing support for class-wide
4497 types that come from the limited view.
4498 * exp_attr.adb (Attribute_Address): Check class-wide type
4499 interfaces using the underlying type to handle limited-withed
4501 (Attribute_Tag): Check class-wide type interfaces using
4502 the underlying type to handle limited-withed types.
4504 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4506 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
4507 over a subtype of a type with a static predicate, taking into
4508 account the predicate function of the parent type and the bounds
4509 given in the loop specification.
4510 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
4511 a loop specification that is a subtype indication whose type mark
4512 is a type with a static predicate, inherit predicate function,
4513 used to build case statement for rewritten loop.
4515 2017-09-08 Justin Squirek <squirek@adacore.com>
4517 * lib-load.adb: Modify printing of error message to exclude file
4520 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4522 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
4523 don't inline subprograms declared in both visible and private
4525 (In_Package_Spec): previously In_Package_Visible_Spec; now
4526 detects subprograms declared both in visible and private parts
4529 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4531 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
4532 the type is an anonymous array in an object declaration, whose
4533 component type has an invariant, use the object declaration
4534 as the insertion point for the invariant procedure, given that
4535 there is no explicit type declaration for an anonymous array type.
4537 2017-09-08 Bob Duff <duff@adacore.com>
4539 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.

4548 source file is missing.
4550 2017-09-08 Bob Duff <duff@adacore.com>
4553 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
4554 Default_WCEM by default (i.e. if the encoding is not specified
4555 by the Form string).
4557 2017-09-08 Bob Duff <duff@adacore.com>
4559 * s-trasym.ads (Hexa_Traceback): If
4560 Suppress_Hex is True, print "..." instead of a hexadecimal
4562 * s-trasym.adb: Ignore No_Hex in this version.
4565 2017-09-08 Bob Duff <duff@adacore.com>
4567 * debug.adb: Minor reformatting.
4569 2017-09-08 Bob Duff <duff@adacore.com>
4571 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
4572 code so it doesn't trigger an "uninit var" warning.
4574 2017-09-08 Nicolas Roche <roche@adacore.com>
4576 * s-hibaen.ads: Remove obsolete file.
4578 2017-09-08 Arnaud Charlet <charlet@adacore.com>

4595 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4597 * debug.adb (dA): Adjust comment.
4598 * gnat1drv.adb (Gnat1drv): Likewise.
4599 * opt.ads (List_Representation_Info_Extended): New variable.
4600 * repinfo.adb (List_Record_Info): Split implementation into...
4601 (Compute_Max_Length): ...this. Recurse on records if requested.
4602 (List_Record_Layout): Likewise.
4603 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
4604 statement, accept '0' and set List_Representation_Info_Extended
4606 * usage.adb (Usage): Document new -gnatRe variant.
4608 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4610 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
4611 Do not save the given entity in the global variable Default_Pool
4612 if the pragma appears within a generic unit.
4614 2017-09-08 Bob Duff <duff@adacore.com>
4616 * errout.adb (Delete_Warning): Do not
4617 decrement Warnings_Treated_As_Errors. This is called before
4618 Warnings_Treated_As_Errors has been incremented to account for
4619 this warning. Decrementing it here can lead to negative values
4620 of Warnings_Treated_As_Errors, raising Constraint_Error in
4621 checks-on builds, and causing the compiler to return an error
4622 code in checks-off builds.
4624 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4626 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
4627 entities of named concurrent types as Ref_Id and not of anonymous
4628 concurrent objects (because callers already know when a conversion
4629 is necessary and can easily do it); also, do not expect protected
4630 types or protected objects as Context_Id (because no flow-related
4631 SPARK pragmas are attached there); reflect these changes in a
4632 more precise comment.
4634 2017-09-08 Olivier Hainque <hainque@adacore.com>
4636 * g-altive.ads: Add documentation.
4638 2017-09-08 Bob Duff <duff@adacore.com>

4641 * erroutc.ads: Comment fix.
4643 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4645 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
4646 for compatibility of component types of formal and actual in an
4647 instantiation of a child unit, when the component type of the
4648 formal is itself a formal of an enclosing generic.
4650 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4652 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
4653 sem_prag.adb to make it available for GNATprove; for concurrent
4654 types replace custom scope climbing with Scope_Same_Or_Within; for
4655 single concurrent objects add scope climbing (with Scope_Within),
4656 which was not there (that's the primary semantic change of this
4657 commit); also, when comparing a single concurrent object with
4658 its corresponding concurrent type rely on equality of types,
4659 not of objects (because that's simpler to code).
4660 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
4661 (Analyze_Global_Item): adjust special-casing of references to the
4662 current instance of a concurrent unit in the Global contracts
4663 of task types and single tasks objects; similar for references
4664 in the protected operations and entries of protected types and
4665 single protected objects (in all these cases the current instance
4666 behaves as an implicit parameter and must not be mentioned in
4667 the Global contract).
4669 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4671 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
4672 function calls returning a record within a subprogram call,
4675 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4677 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
4678 name that designates the current instance of a child unit in its
4679 own body and appears as the prefix of a reference to an entity
4680 local to the child unit.
4681 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
4684 2017-09-08 Yannick Moy <moy@adacore.com>

4691 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
4692 warnings on internal units in configurable run time mode.
4694 2017-09-08 Bob Duff <duff@adacore.com>
4696 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
4697 representation items from interfaces that the derived type
4698 implements, not just from the parent type.
4699 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
4700 this to return an empty list when there are no interfaces.
4701 * einfo.ads, sem_ch13.adb: Minor comment fixes.
4702 * sem_attr.adb: Minor comment fix.
4704 2017-09-08 Doug Rupp <rupp@adacore.com>
4706 * sigtramp-vxworks.c [i386]: Adjust the kernel context for
4709 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4711 * exp_ch4.adb (Expand_N_Allocator): Generate a
4712 call to Allocate_Any_Controlled when the allocation does not
4713 require any initialization.
4715 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4717 * sem_util.adb (Copy_Node_With_Replacement):
4718 Update the Renamed_Object field of a replicated object renaming
4721 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
4723 * exp_ch9.adb (Is_Pure_Barrier): Allow type
4724 conversions and components of objects. Simplified the detection
4725 of the Count attribute by identifying the corresponding run-time
4728 2017-09-08 Yannick Moy <moy@adacore.com>
4730 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
4731 sem_type.adb, sinfo.ads: Minor reformatting.
4733 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4735 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
4736 of Freeze_Profile, used to inhibit the freezing of the profile
4737 of an expression function declared within a nested package, when
4738 some type in the profile depends on a private type declared in
4739 an enclosing package.
4741 2017-09-08 Bob Duff <duff@adacore.com>
4743 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
4744 the subunit case. It's still OK to set it in the "missing subunits"
4745 case, because that won't cause the obsolete .ali files that cause
4748 2017-09-08 Bob Duff <duff@adacore.com>
4750 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
4751 unclear why this didn't cause a warning.
4752 * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
4753 pragmas. It's unclear why this didn't cause an error.
4755 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4757 * exp_spark.adb (Expand_SPARK_N_Object_Renaming_Declaration):
4759 (Expand_SPARK_Potential_Renaming): Code clean up.
4760 * sem_prag.adb (Analyze_Initialization_Item): Add a guard in case
4761 the item does not have a proper entity.

4779 * repinfo.adb (List_Record_Info): During first loop,
4780 do not override the normalized position and first bit
4781 if they have already been set. Move fallback code
4782 for the packed case to the case where it belongs.
4783 * sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
4784 Also adjust the normalized position of components.
4785 (Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise.
4787 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4789 * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
4790 the placement of a primitive operation O that renames an operation
4791 R declared in an inner package, and which is thus not a primitive
4792 of the dispatching type of O. In this case O is a new primitive
4793 and does not inherit its dispatch table position from R (which

4798 * sem_dim.adb (Analyze_Dimension_If_Expression,
4799 Analyze_Dimension_Case_Expression): new subprograms to verify
4800 the dimensional correctness of Ada2012 conditional expressions,
4801 and set properly the dimensions of the construct.
4802 * sem_res.adb (Resolve_If_Expression, Resolve_Case_Expression)):
4803 call Analyze_Dimension.
4805 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4807 * sem_type.adb (Expand_Interface_Conversion): Prevent an infinite
4808 loop on an interface declared as a private extension of another
4809 synchronized interface.

4813 * sem_ch12.adb (Check_Generic_Parent): New procedure within
4814 Analyze_Associations, to handle actual packages that depend on
4815 previous instances. If a package IAP that is an instantiation is
4816 used as an actual in a subsequent instantiation SI in the same
4817 scope, and IAP has a body, IAP must be frozen before SI. If
4818 the generic parent of IAP is itself declared in a previous
4819 instantiation in the same scope, that instantiation must also
4820 be frozen before SI.
4821 (Install_Body): Prevent double insertion of freeze node for
4824 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>

4832 * sem_ch13.adb (Analyze_Aspect_Specifications, case
4833 Linker_Section): If the aspect applies to an object declaration
4834 with explicit initialization, do not delay the freezing of the
4835 object, to prevent access-before-elaboration in the generated
4836 initialization code.
4838 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4840 * a-wtdeio.adb (Put, all versions): Use Long_Long_Integer
4841 (Integer_Value (Item)) when the size of the fixed decimal type
4842 is larger than Integer.
4844 2017-09-07 Eric Botcazou <ebotcazou@adacore.com>
4847 * gcc-interface/decl.c (copy_and_substitute_in_layout): Put the fields
4848 in order of increasing position in more cases.
4850 2017-09-07 Yannick Moy <moy@adacore.com>

4876 in the external name of the elaboration flag. Required to fix
4877 the regressions introduced by the initial version of this patch.
4879 2017-09-07 Bob Duff <duff@adacore.com>
4881 * sem_ch6.adb (Analyze_Function_Return): Do not
4882 insert an explicit conversion to force the displacement of the
4883 "this" pointer to reference the secondary dispatch table in the
4884 case where the return statement is returning a raise expression,
4885 as in "return raise ...".
4887 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4889 * sem_disp.adb (Is_User_Defined_Equality): Removed procedure.

4909 to handle properly various cases of type conversions where the
4910 target type and/or the expression carry dimension information.
4911 (Dimension_System_Root); If a subtype carries dimension
4912 information, obtain the source parent type that carries the

4917 * g-socket.adb, g-socket.ads (GNAT.Sockets.To_Ada): New routine.
4919 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4921 * exp_attr.adb (Expand_N_Attribute_Reference, case 'Constrained):
4922 If the prefix is a reference to an object, rewrite it as an
4923 explicit dereference, as required by 3.7.2 (2) and as is done
4924 with most other attributes whose prefix is an access value.
4926 2017-09-07 Bob Duff <duff@adacore.com>
4928 * par-ch13.adb: Set the Inside_Depends flag if we are inside a
4929 Refined_Depends aspect.

4988 clause for a unit U appears in a context that includes a regular
4989 with_clause on U, rewrite the redundant private clause into a null

5046 generated in the IP routines by means of keeping separate
5047 the initialization of the object components from the
5048 initialization of its dispatch tables. (Init_Secondary_Tags):

5050 Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;

5052 because the type of one of its formals has been changed.
5053 * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
5054 modified. Instead of receiving a pointer to an object this
5055 routine receives now a primary tag.

5057 additional formal: the tag of the primary dispatch table.
5058 * exp_disp.ads (Elab_Flag_Needed): New subprogram.
5059 * exp_disp.adb (Elab_Flag_Needed): New subprogram.

5091 is now consulted not only for abstract states and variables,
5092 but for all kinds of items.
5093 (Collect_Subprogram_Inputs_Outputs): Do not process formal
5094 generic parameters, because unlike ordinary formal parameters,
5095 generic formals only act as input/ outputs if they are explicitly
5096 mentioned in a Global contract.
5098 2017-09-07 Yannick Moy <moy@adacore.com>

5162 secondary stack for all functions that return limited tagged
5163 types -- just do it for dispatching calls. Misc cleanup.
5164 * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
5165 remove qualifications and type conversions. Fix various bugs
5166 where only a single level of qualification or conversion was
5167 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
5169 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
5172 2017-09-07 Ed Schonberg <schonberg@adacore.com>

5178 of body is a predicate function as well.
5179 (Resolve_Aspect_Expressions, Resolve_Name): For a component
5180 association, only the expression needs resolution, not the name.
5181 (Resolve_Aspect_Expressions, case Predicates): Construct and
5182 analyze the predicate function declaration in the scope of the
5183 type, before making the type and its discriminants visible.

5226 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
5227 requested. Previously, the -do switch meant "run Elab_New and
5228 Elab_Old and use the order chosen by Elab_Old, possibly with
5229 debugging printouts comparing the two orders." Now it means
5230 "do not run Elab_New." This is of use if there are bugs that
5231 cause Elab_New to crash.

5278 entity of a mutable type and the right-hand side is a conditional
5279 expression, resolve the alternatives of the conditional using
5280 the base type of the target entity, because the alternatives

5286 * checks.adb (Apply_Predicate_Check): If the expression is an
5287 aggregate that is the RHS of an assignment, apply the check to
5288 the LHS after the assignment, rather than to the aggregate. This
5289 is more efficient than creating a temporary for the aggregate,
5290 and prevents back-end crashes when the aggregate includes a

5314 treatment for warning vs. style messages in inlinings and
5315 instantiations. Prevents blowups on calls to Warn_Insertion for
5316 style messages, which should not be called in that case because
5317 Warning_Msg_Char is not set.

5346 adjustment of the sloc until after the correct adjustment has
5347 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore

5454 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
5455 we include the proper header. Otherwise, we just declare the necessary
5456 things from the capabilities library. This is so we can build on
5457 machines without that library, while still enabling that library.
5458 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
5459 simply return 0 if the library is not present, or not included

5484 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
5485 (eventually) override the default.
5486 * pprint.adb (Expression_Image) If the new flag is set, then
5487 suppress the ".all" suffix when displaying a dereference whose
5488 prefix is a use of a value-capturing compiler temp of the sort
5489 generated by Expr_Util.Remove_Side_Effects .

5509 * sem_ch3.adb (Derived_Type_Declaration): Use

5690 Move Ada.Command_Line.Response_File to System.Response_File,
5691 and make Ada.Command_Line.Response_File into a rename of
5692 System.Response_File. This is to avoid having gnatbind depend
5693 Ada.Command_Line, which would damage the bootstrap process now
5694 that Ada.Command_Line contains modern Ada (the raise expression).
5695 * gnatbind.adb: Avoid dependence on
5696 Ada.Command_Line. Depend on System.Response_File instead
5697 of Ada.Command_Line.Response_File. Change one call to
5698 Ada.Command_Line.Command_Name to use Fill_Arg. Change one call
5699 to Ada.Command_Line.Argument_Count to use Arg_Count.
5700 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
5702 2017-09-06 Bob Duff <duff@adacore.com>
5704 * frontend.adb (Frontend): Skip -gnatec=gnat.adc

5768 rule in 6.5.1 (7/2): if a renaming is a completion of a subprogram
5769 with No_Return, the renamed entity must be No_Return as well.
5771 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
5773 * exp_ch5.adb, freeze.adb, exp_ch4.adb, exp_ch6.adb, lib-xref.adb:

5790 * freeze.adb (Freeze_Entity): Do not generate a freeze
5791 node for a generic unit, even if it includes delayed aspect

5832 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5834 * exp_ch5.adb (Make_Field_Assign): If the type
5835 of the right-hand side has stored constraint, use its values
5836 (except for those that are renamings of parent discriminants)
5837 to produce additional assignments for the discriminants of the
5838 left-hand side, which are invisible in the righ-hand side and
5839 not retrievable as selected components.
5841 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5843 * sem_util.adb (Needs_One_Formal): The first formal of such a
5844 function must be a controlling formal, so that Obj.F (X, Y)
5845 can have the interpretation F(Obj)(X, Y).
5846 * sem_util.ads: Clarify documentation.
5848 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>

5863 * sem_ch12.adb (Analyze_Subprogram_Instantiation): Propagate
5864 No_Return flag to instance if pragma applies to generic unit. This
5865 must be done explicitly because the pragma does not appear
5866 directly in the generic declaration (unlike the corresponding
5867 aspect specification).

5878 * exp_ch4.adb (Handle_Changed_Representation): For an untagged
5879 derived type with a mixture of renamed and constrained parent
5880 discriminants, the constraint for the target must obtain the
5881 discriminant values from both the operand and from the stored
5882 constraint for it, given that the constrained discriminants are
5883 not visible in the object.
5884 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
5885 side may be derived from that of the left-hand side (as in the
5886 case of an assignment with a change of representation) so the
5887 discriminant to be used in the retrieval of the value of the
5888 component must be the entity in the type of the right-hand side.
5890 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
5892 * sem_ch3.adb, sem_ch7.adb, sem_util.adb, g-debpoo.adb, sem_ch4.adb,

5916 * sem_ch4.adb (Analyze_Set_Membership): If an alternative
5917 in a set membership is an overloaded enumeration literal, and
5918 the type of the alternative is resolved from a previous one,
5919 replace the entity of the alternative as well as the type,
5920 to prevent inconsistencies between the entity and the type.

6429 a cleanup if the statements of the handler cannot raise.
6430 (process_freeze_entity): Use Is_Record_Type.
6431 (process_type): Likewise.
6433 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>

6455 (is_stored_discriminant): New predicate.
6456 (copy_and_substitute_in_layout): Consider only
6457 stored discriminants and check that original fields are present

6463 * exp_ch6.adb (Expand_Call_Helper): When locating the
6464 accessibility entity created for an access parameter, handle
6465 properly a reference to a formal of an enclosing subprogram. if
6466 the reference appears in an inherited class-wide condition, it
6467 is the rewriting of the reference in the ancestor expression,
6468 but the accessibility entity must be that of the current formal.
6470 2017-05-02 Javier Miranda <miranda@adacore.com>
6472 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

6507 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
6508 procedure body for a local (sub)type declaration within a
6509 predicate function. Invariant checks do not apply to these, and
6510 the expansion of the procedure will happen in the wrong scope,
6511 leading to misplaced freeze nodes.
6513 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6515 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
6516 to analyze generated actions. If the main unit is a body,

6519 2017-05-02 Arnaud Charlet <charlet@adacore.com>
6521 * einfo.adb (Declaration_Node): flip branches of
6522 an IF statement to avoid repeated negations in its condition;

6527 * sem_case.adb: Remove extra spaces in parameter declarations.
6529 2017-05-02 Justin Squirek <squirek@adacore.com>
6531 * usage.adb: Replace space with hyphen ("run time" -> "run-time")

6552 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
6553 Refine predicate for the case where the primitive operation
6554 is a renaming of equality. An overriding operation that is
6555 a user-defined renaming of predefined equality inherits its
6556 slot from the overridden operation. Otherwise it is treated
6557 as a predefined op and occupies the same predefined slot as
6558 equality. A call to it is transformed into a call to its alias,
6559 which is the predefined equality. A dispatching call thus uses
6560 the proper slot if operation is further inherited and called
6561 with class-wide arguments.
6563 2017-05-02 Justin Squirek <squirek@adacore.com>
6565 * errout.adb (Set_Msg_Text): Add a case to switch the message

6568 * opt.ads Add a new Warning_Mode value for new switch
6569 * switch-b.adb (Scan_Binder_Switches): Add case for the binder
6570 to handle new warning mode

6576 * sem_prag.adb (Process_Conversion): Reject an intrinsic operator
6577 declaration that operates on some fixed point type.

6599 statement if the initialization call is a null procedure, as
6600 can happen with a controlled type with no explicit Initialize
6601 procedure, or an array of such.
6602 * exp_ch7.adb (Process_Object_Declaration): For a type with
6603 controlled components that has a trivial Initialize procedure,
6604 insert declaration for finalization counter after object

6607 finalization block and attendant declarations if component has
6608 a trivial Initialize procedure.
6609 (Make_Init_Call): Do not generate a call if controlled type has
6610 a trivial Initialize procedure.
6612 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>
6614 * g-forstr.ads (Data): Move Format component last.
6615 * g-forstr.adb ("+"): Adjust for above change.
6616 * g-rewdat.ads (Buffer): Move Buffer, Current, Pattern and Value last.

6640 2017-05-02 Gary Dismukes <dismukes@adacore.com>
6642 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
6643 parameter Array_Comp to indicate the case of an array object
6644 with null-excluding components.
6645 * checks.adb (Null_Exclusion_Static_Checks):
6646 Call Compile_Time_Constraint_Error instead of
6647 Apply_Compile_Time_Constraint_Error in the component case. Also
6648 call that when Array_Comp is True, with an appropriate warning for
6649 the array component case. Only create an explicit initialization
6650 by null in the case of an object of a null-excluding access type
6651 (and no longer do that in the component case).
6652 * sem_ch3.adb (Check_Component): Add a Boolean parameter
6653 Array_Comp defaulted to False. Pass Empty for the Comp
6654 actual when calling Null_Exclusion_Static_Checks in the case
6655 where Comp_Decl matches Object_Decl, because we don't have a
6656 component in that case. In the case of an object or component
6657 of an array type, pass True for Array_Comp on the recursive call

6662 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
6663 compute the linux priority from the Ada priority. Call this everywhere
6664 required. In particular, the previous version was not doing this
6665 computation when setting the ceiling priority in various places. It
6666 was just converting to C.int, which results in a ceiling that is off
6669 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6671 * sem_ch3.adb: Comment predicate inheritance.

6688 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
6689 here from exp_ch9, to recognize objects whose creation requires
6690 dynamic allocation, so that the proper warning can be emitted
6691 when restriction No_Implicit_Heap_Allocation is in effect.
6692 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
6693 to emit proper warning when an object that requires dynamic

6703 visibility rules for equality operators that apply within an
6704 instantiation apply within an inlined body.

6737 settings of Optimize_Alignment at the end.
6739 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
6741 * checks.adb (Apply_Constraint_Check): Do not apply
6742 a discriminant check when the associated type is a constrained

6771 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
6773 2017-05-02 Bob Duff <duff@adacore.com>
6775 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6776 to find primitive ops, instead of using an Identifier that will
6777 later be looked up. This is necessary because these ops are not
6778 necessarily visible at all places where we need to call them.
6779 * exp_util.ads: Minor comment fix.
6781 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6783 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6784 references are fully conformant if they are both expansions
6785 of the discriminant of a protected type, within one of the
6786 protected operations. One occurrence may be expanded into a
6787 constant declaration while the other is an input parameter to
6788 the corresponding generated subprogram.

6824 rewrite the reference as Any_Id to prevent cascaded errors or
6825 compiler loops when such an entity is used in an address clause.
6827 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6829 * gcc-interface/decl.c (components_to_record): Add missing guard.

6833 * gcc-interface/decl.c (components_to_record): Add more comments.
6834 Put back pending fields onto the regular list if the misalignment
6835 happens to cancel itself.
6837 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6839 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
6840 controlling actual in a prefixed call, preserve the original node
6841 information if the prefix itself has been rewritten, for ASIS use.

6845 * exp_ch6.adb (Insert_Post_Call_Actions):
6846 Code clean up. Insert the post-call actions after an enclosing

6852 * freeze.adb (Check_Component_Storage_Order): If there is a clause
6853 for the component, also reject the attribute if the component
6854 doesn't end on a byte boundary and its scalar storage order is
6855 different from that of the enclosing record type.

6891 * sem_util.ads, sem_util.adb (Might_Raise): New function
6892 that replaces Is_Exception_Safe, but has the opposite
6893 sense. Is_Exception_Safe was missing various cases -- calls inside
6894 a pragma Debug, calls inside an 'if' or assignment statement,
6895 etc. Might_Raise now walks the entire subtree looking for things
6897 * exp_ch9.adb (Is_Exception_Safe): Remove.
6898 (Build_Protected_Subprogram_Body): Replace call to
6899 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use

6931 * sem_ch13.adb (Analyze_Aspect_Specifications, case
6932 Interrupt_Handler and Attach_Handler): Generate reference
6933 to protected operation to prevent spurious warnings about
6934 unreferenced entities. Previous scheme failed with style checks
6937 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6939 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6940 that follows an expression function must not be relocated to
6941 the generated body, because it applies to the code that follows.

6952 * a-cforse.adb: minor style fix in comment.
6954 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6956 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
6957 initialize Block_Decls variable.

6970 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6972 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
6973 node between access types, freeze the designated type as well,
6974 so that dispatch table pointers are created in the proper scope,
6975 and not in the constructed body of the expression function.
6977 2017-04-28 Bob Duff <duff@adacore.com>
6979 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6980 value makes large compilations faster, but small compilations slower.
6982 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6984 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
6986 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6988 * erroutc.adb (Compilation_Errors): Do not consider info messages

7002 2017-04-28 Ed Schonberg <schonberg@adacore.com>
7004 * sem_res.adb (In_Instance_Code): New predicate in
7005 Valid_Conversion, to determine whether a type conversion appears
7006 as (or within) an actual for a formal object. Type conversions
7007 in instances are not rechecked in Valid_Conversion because
7008 visibility changes between generic location andi instance may
7009 lead to spurious errors, but conversions within an actual must be
7010 fully checked, and they are not fully resolved when pre-analyzing
7013 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
7015 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
7016 New_Copy_Tree instead of Relocate_Node as any subsequent copies
7017 of the relocated node will have mangled Parent pointers.

7055 (Restore_Warnings): Likewise.
7056 (Save_Warnings): Likewise.
7057 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
7058 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
7059 components_to_record.
7060 (gnu_field_to_gnat): New function.
7061 (warn_on_field_placement): Likewise.

7063 parameters. Rename local variables and adjust recursive call.
7064 Rework final scan of the field list and implement warnings on the
7065 problematic placement of specific sorts of fields.

7074 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
7075 For efficiency, cache results of Is_Internal_File_Name and
7076 Is_Predefined_File_Name in the Units table. This avoids a lot
7077 of repeated text processing.
7079 2017-04-27 Emmanuel Briot <briot@adacore.com>
7081 * g-comlin.adb (Sort_Sections): remove useless test.

7085 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
7086 allow the use of regular equality over elements in contracts.
7087 (Formal_Model): Ghost package containing model functions that are
7088 used in subprogram contracts.
7089 (Current_To_Last): Removed, model functions should be used instead.
7090 (First_To_Previous): Removed, model functions should be used instead.
7091 (Strict_Equal): Removed, model functions should be used instead.
7092 (No_Overlap): Removed, model functions should be used instead.
7093 (Equivalent_Keys): Functions over cursors are removed. They were
7094 awkward with explicit container parameters.
7095 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to

7106 * gnat1drv.adb: Code cleanup.
7108 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7110 * exp_util.adb (Replace_Entity): The prefix of a 'Result
7111 attribute reference in a post- condition is the subprogram to
7112 which the condition applies. If the condition is inherited
7113 by a type extension, the prefix becomes a reference to the
7114 inherited operation, but there is no need to create a wrapper
7115 for this operation, because 'Result is expanded independently
7116 when elaborating the postconditions.
7118 2017-04-27 Bob Duff <duff@adacore.com>
7120 * sinput.adb: Minor code cleanup.
7121 * namet.adb (Append): Create faster versions of

7127 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
7128 Remove unused function.
7129 * alloc.ads (Nodes_Initial): Use a much larger value, because
7130 the compiler was spending a lot of time copying the nodes table
7131 when it grows. This number was chosen in 1996, so is rather out
7132 of date with current memory sizes. Anyway, it's virtual memory.
7133 Get rid of Orig_Nodes_...; use Node_... instead.
7134 * atree.adb (Lock): Do not release the Nodes tables; it's a
7136 Orig_Nodes_ ==> Nodes_
7137 * nlists.adb: Orig_Nodes_ ==> Nodes_
7138 * g-table.adb: Remove unused "with" clause.
7139 * g-table.ads, table.ads: Remove Big_Table_Type, which should
7140 not be used by clients.
7141 * g-dyntab.adb (Last_Allocated): New function

7165 for qualified expressions, type conversions, and unchecked
7167 * sem_util.adb (Compile_Time_Constraint_Error): Merge the
7168 processing for Ada 83 and instances.
7169 (Object_Access_Level): Merge the processing for indexed components
7170 and selected components.
7171 * uname.adb (Add_Node_Name): Merge the processing for stubs.

7182 of Expand_Dispatching_Call. If the denoted subprogram has a
7183 class-wide precondition, this is the only precondition that
7184 applies to the call, rather that the class-wide preconditions
7185 that may apply to the body that is executed. (This is specified
7188 2017-04-27 Yannick Moy <moy@adacore.com>
7190 * gnat1drv.adb (Adjust_Global_Switches): Issue
7191 a warning in GNATprove mode if the runtime library does not
7192 support IEEE-754 floats.

7196 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
7197 is itself inherited it does not carry any contract information,
7198 so examine its parent operation which is its Alias.
7200 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7202 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
7203 prefix can be an object reference in which case Obj'Image (X)
7204 can only be interpreted as an indexing of the parameterless
7205 version of the attribute.
7206 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
7207 an indexing or a slice operation if the attribute does not require
7208 parameters. In Ada2012 'Image also belongs in this category,
7209 and A'Image (lo .. hi) is legal and must be parsed as a slice.
7211 2017-04-27 Yannick Moy <moy@adacore.com>
7213 * exp_ch4.adb: Minor reformatting.
7214 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,
7215 disable the CodePeer and C generation modes. Similar to the
7216 opposite actions done in CodePeer mode.

7346 (Move, Release_Threshold).
7347 * g-table.ads, g-table.adb: This is now just a thin wrapper

7399 * freeze.adb (Build_Inherited_Condition_Pragmas): New procedure,
7400 subsidiary of Check_Inherited_Conditions, to build pragmas for an

7871 to manage the secondary stack when an enclosing scope already
7872 performs this functionality (aka relaxed management). Switch
7873 -gnatd.s may be used to force strict management in which case
7874 the block will manage the secondary stack unconditionally. Add

7884 this transformation is performed int the back-end. However,
7885 the type of the call itself must be the non-limited view, to

7894 subprogram created for primitive operations with class-wide
7895 pre/postconditions that contain calls to other primitives. The
7896 clone holds the body of the original primitive, but the
7897 pre/postonditions do not apply to it. The original body is
7898 rewritten as a wrapper for a call to the clone.

7900 the flag is set, no code for the corresponding pre/postconditions
7901 is inserted into its body.

8453 processing a component of a larger record, and we need to prevent
8454 further expansion for the unchecked union.
8455 (Expand_Attribute_Reference, case 'Write): If the type is
8456 an unchecked_union, check whether enclosing scope is a Write
8457 subprogram. Replace attribute with a Raise_Program_Error if the
8458 discriminants of the unchecked_union type have not default values
8459 because such a use is erroneous..

8547 operand as universal real when the operand is a multiplication
8548 or a division where both operands are of any fixed type.

8679 to return if an interface type is encountered and add
8680 condition to convert the formal parameter to its class-wide
8681 counterpart if Work_Typ is abstract.

8703 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
8704 (10-15): if derived type T with progenitors is abstract,
8705 and primitive P of this type inherits non-trivial classwide
8706 preconditions from both a parent operation and from an interface
8707 operation, then the inherited operation is abstract if the parent
8708 operation is not null.
8709 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface

8749 * a-numeri.ads: Change the encoding of Greek letter Pi from
8750 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
8751 to indicate the encoding. We considered using a byte order mark
8752 (BOM), but that causes various trouble (misc software eats the
8753 BOM, if you have a patch with a BOM, then it's not at the start
8754 of the patch, so it's not a BOM, the BOM affects with-ing files,

8932 Set_Elaboration_Entity_Required when requested to preserve
8933 control flow, to ensure the unit elaboration is materialized at
8934 bind time, resulting in the inclusion of the unit object file
8935 in the executable closure at link time.
8937 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8939 * exp_dbug.adb: In Debug_Renaming_Declaration,
8940 when dealing with indexed component, accept to produce a renaming
8941 symbol when the index is an IN parameter or when it is a name
8942 defined in an outer scope.
8944 2017-04-25 Yannick Moy <moy@adacore.com>
8946 * errout.adb (Error_Msg): Adapt continuation
8947 message in instantiations and inlined bodies for info messages.
8949 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8951 * fname.adb (Has_Internal_Extension): Add pragma Inline.
8952 Use direct 4-character slice comparisons.
8954 pragma Inline. (Has_Suffix): Delete.
8955 (Is_Internal_File_Name):
8956 Test Is_Predefined_File_Name first.
8957 (Is_Predefined_File_Name):
8958 Use direct slice comparisons as much as possible and limit all
8959 comparisons to at most 8 characters.
8961 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8963 * checks.adb (Insert_Valid_Check): Code cleanup.
8964 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8965 (Expand_Actuals): Generate proper copy-back for a validation
8966 variable when it acts as the argument of a type conversion.
8967 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8968 predicate to operate on type qualifications.
8970 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8972 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8975 2017-04-25 Bob Duff <duff@adacore.com>
8977 * sem_prag.adb (No_Return): Give an error if the pragma applies
8978 to a body. Specialize the error for the specless body case,
8979 as is done for (e.g.) pragma Convention.
8980 * debug.adb: Add switch -gnatd.J to disable the above legality
8981 checks. This is mainly for use in our test suite, to avoid
8982 rewriting a lot of illegal (but working) code. It might also
8983 be useful to customers. Under this switch, if a pragma No_Return
8984 applies to a body, and the procedure raises an exception (as it
8985 should), the pragma has no effect. If the procedure does return,
8986 execution is erroneous.
8988 2017-04-25 Bob Duff <duff@adacore.com>
8990 * exp_ch6.adb (Expand_Actuals): This is the
8991 root of the problem. It took N as an 'in out' parameter, and in
8992 some cases, rewrote N, but then set N to Original_Node(N). So
8993 the node returned in N had no Parent. The caller continued
8994 processing of this orphaned node. In some cases that caused a
8995 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8996 and trips over the Empty Parent). The solution is to make N an
8997 'in' parameter. Instead of rewriting it, return the list of
8998 post-call actions, so the caller can do the rewriting later,
8999 after N has been fully processed.
9000 (Expand_Call_Helper): Move most of Expand_Call here. It has
9001 too many premature 'return' statements, and we want to do the
9002 rewriting on return.
9003 (Insert_Post_Call_Actions): New procedure to insert the post-call
9004 actions in the appropriate place. In the problematic case,
9005 that involves rewriting N as an Expression_With_Actions.
9006 (Expand_Call): Call the new procedures Expand_Call_Helper and
9007 Insert_Post_Call_Actions.
9009 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9011 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
9012 properly type derived from generic formal types, to handle
9013 properly modified version of ACATS 4.1B B611017.
9015 2017-04-25 Javier Miranda <miranda@adacore.com>
9017 * exp_unst.adb (Subp_Index): Adding missing
9018 support for renamings and functions that return a constrained
9019 array type (i.e. functions for which the frontend built a
9020 procedure with an extra out parameter).
9022 2017-04-25 Pascal Obry <obry@adacore.com>
9024 * s-string.adb: Minor code clean-up.
9026 2017-04-25 Bob Duff <duff@adacore.com>

9031 function for Non_Blocking_Wait_Process.
9033 2017-04-25 Bob Duff <duff@adacore.com>
9035 * prep.adb (Preprocess): Remove incorrect
9036 Assert. Current character can be ASCII.CR.
9038 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9040 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
9041 convention Stdcall, which has a number of exceptions. Convention
9042 is legal on a component declaration whose type is an anonymous
9043 access to subprogram.
9045 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9047 * sem_ch4.adb: sem_ch4.adb Various reformattings.
9048 (Try_One_Prefix_Interpretation): Use the base type when dealing
9049 with a subtype created for purposes of constraining a private
9050 type with discriminants.
9052 2017-04-25 Javier Miranda <miranda@adacore.com>

9058 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
9059 to enable/disable this warning.
9060 (WA_Warnings): Set warning on late dispatching primitives.
9061 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
9062 that its parent type has a private extension.
9063 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
9065 * usage.adb: Document -gnatw.j and -gnatw.J.
9067 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

9072 2017-04-25 Bob Duff <duff@adacore.com>
9074 * binde.adb (Validate): Do not pass dynamic strings
9075 to pragma Assert, because older compilers do not support that.
9077 2017-04-25 Bob Duff <duff@adacore.com>
9079 * s-fileio.adb (Close): When a temp file is
9080 closed, delete it and clean up its Temp_File_Record immediately,
9081 rather than waiting until later.
9082 (Temp_File_Record): Add File
9083 component, so Close can know which Temp_File_Record corresponds
9084 to the file being closed.
9085 (Delete): Don't delete temp files,
9086 because they are deleted by Close.
9087 (Open): Set the File component
9088 of Temp_File_Record. This requires moving the creation of the
9089 Temp_File_Record to the end, after the AFCB has been created.
9091 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9093 * checks.adb (Insert_Valid_Check): Do not generate
9094 a validity check when inside a generic.
9096 2017-04-25 Yannick Moy <moy@adacore.com>
9098 * sem_res.adb (Resolve_Type_Conversion): Fix bad logic.
9100 2017-04-25 Arnaud Charlet <charlet@adacore.com>

9108 concerning inheritance of class-wide preconditions do not apply
9111 2017-04-25 Bob Duff <duff@adacore.com>
9113 * s-ficobl.ads: Minor comment fix.
9115 2017-04-25 Yannick Moy <moy@adacore.com>
9117 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
9118 conversions from float to integer in GNATprove mode.
9119 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
9120 to call Apply_Type_Conversion_Checks, so that range checks
9121 are properly positioned when needed on conversions, including
9122 when converting from float to integer. (Determine_Range): In
9123 GNATprove mode, take into account the possibility of conversion
9124 from float to integer.
9125 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
9126 check on conversions from fixed-point to integer, not anymore
9127 on conversions from floating-point to integer, when in GNATprove
9130 2017-04-25 Yannick Moy <moy@adacore.com>
9132 * checks.adb (Determine_Range_R): Special case type conversions
9133 from integer to float in order to get bounds in that case too.
9134 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
9135 mode, for computations involved in interval checking.

9149 * exp_attr.adb (Make_Range_Test): Add processing for validation
9150 variables to avoid extra reads and copies of the prefix.
9151 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
9152 variables in order to reflect any changes done in the variable
9153 back into the original object.
9154 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
9155 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

9161 generate Finalize_Address routines for CodePeer.
9163 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9165 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
9166 Analyze_Pre_Post_Condition, to implement the legality checks
9167 mandated by AI12-0131: Pre'Class shall not be specified for an
9168 overriding primitive subprogram of a tagged type T unless the
9169 Pre'Class aspect is specified for the corresponding primitive
9170 subprogram of some ancestor of T.
9172 2017-04-25 Bob Duff <duff@adacore.com>
9174 * sem_ch8.adb (Use_One_Type): If a use_type_clause
9175 is redundant, set its Used_Operations to empty. This is only
9176 necessary for use clauses that appear in the parent of a generic
9177 child unit, because those use clauses get reanalyzed when we
9178 instantiate the generic, and we don't want the Used_Operations
9179 carried over from the original context (where it was probably
9182 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9184 * exp_ch6.adb: Minor reformatting.
9186 2017-04-25 Bob Duff <duff@adacore.com>
9188 * sem_prag.adb (Process_Restrictions_Or_Restriction_Warnings):

9191 (Current_Sem_Unit) to find the correct casing.
9192 * par.adb (Par): Null out Current_Source_File, to ensure that
9193 the above bugs won't rear their ugly heads again.
9195 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9197 * sem_ch8.adb (Find_Type): For an attribute reference
9198 'Class, if prefix type is synchronized and previous errors
9199 have suppressed the creation of the corresponding record type,
9200 create a spurious class-wide for the synchonized type itself,
9201 to catch other misuses of the attribute
9203 2017-04-25 Steve Baird <baird@adacore.com>
9205 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode

9209 if CodePeer_Mode is True, then don't generate the
9210 tag checks for the result of call to an instance of
9211 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
9212 descendant of" check and the accessibility check).
9214 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9216 * sem_ch13.adb: Code cleanups.
9217 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

9222 * exp_ch4.adb (Library_Level_Target): New function.
9223 (Expand_Concatenate): When optimization is enabled, also expand
9224 the operation out-of-line if the concatenation is present within
9225 the expression of the declaration of a library-level object and
9226 not only if it is the expression of the declaration.
9228 2017-04-25 Bob Duff <duff@adacore.com>
9230 * freeze.adb (Freeze_Object_Declaration): Do
9231 not Remove_Side_Effects if there is a pragma Linker_Section,
9232 because in that case we want static initialization in the
9233 appropriate section.
9235 2017-04-25 Gary Dismukes <dismukes@adacore.com>
9237 * exp_dbug.adb: Minor rewording and reformatting.
9239 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9241 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
9242 handle the proposed changes to rules concerning potentially
9243 unevaluated expressions, to include selected components that
9244 do not depend on discriminants, and indexed components with
9246 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
9247 predicate in quantified expression, and fix bugs in the handling
9248 of case expressions and membership test.
9249 (Analyze_Attribute_Old_Result): use new predicate.
9250 (Analyze_Attribute, case Loop_Entry): ditto.
9252 2017-04-25 Bob Duff <duff@adacore.com>
9254 * s-secsta.adb (SS_Info): Add a comment
9255 explaining why we don't need to walk all the chunks in order to
9256 compute the total size.
9258 2017-04-25 Bob Duff <duff@adacore.com>
9260 * namet.ads, namet.adb (Global_Name_Buffer): Increase the length
9261 of the global name buffer to 4*Max_Line_Length.
9263 2017-04-25 Javier Miranda <miranda@adacore.com>
9265 * exp_ch8.adb (Expand_N_Object_Renaming_Declaration): When creating a
9266 renaming entity for debug information, mark the entity as needing debug
9267 info if it comes from sources.
9269 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9271 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
9272 restriction converning the use of 'Address where the prefix is
9273 of a controlled type.
9275 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>

9289 Preanalyze_Spec_Expression so that resolution takes place as well.
9290 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
9291 internal calls that appear in preconditions of protected
9292 operations, in default values for same, and in contract guards
9293 for contract cases in SPARK.

9297 * a-numaux.ads: Fix description of a-numaux-darwin
9299 (Double): Define to Long_Float.
9300 * a-numaux-vxworks.ads (Double): Likewise.
9301 * a-numaux-darwin.ads
9303 * a-numaux-libc-x86.ads (Double): Define to Long_Long_Float.
9304 * a-numaux-x86.ads: Fix package description.
9305 * a-numaux-x86.adb (Is_Nan): Minor tweak.
9306 (Reduce): Adjust and complete description. Call Is_Nan instead of
9307 testing manually. Use an integer temporary to hold rounded value.
9308 * a-numaux-darwin.adb (Reduce): Likewise.

9320 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
9321 the identity of callable entities therein, because they have been
9322 properly resolved, and prefixed calls may have been rewritten
9325 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
9327 * exp_ch3.adb (Build_Init_Statements): Convert
9328 the expression of the pragma/aspect Secondary_Stack_Size to
9329 internal type System.Parameters.Size_Type before assigning
9330 it to the Secondary_Stack_Size component of the task type's
9331 corresponding record.
9333 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
9335 * sem_eval.adb (Compile_Time_Compare): Reinstate the expr+literal
9336 (etc) optimizations when the type is modular and the offsets

9341 * s-osinte-freebsd.ads: Minor comment tweaks
9343 2017-04-25 Javier Miranda <miranda@adacore.com>
9345 * urealp.adb (UR_Write): Reverse previous patch
9346 adding documentation on why we generate multiplications instead
9347 of divisions (needed to avoid expressions whose computation with
9348 large numbers may cause division by 0).
9350 2017-04-25 Bob Duff <duff@adacore.com>
9352 * erroutc.adb (Set_Specific_Warning_Off,
9353 Set_Warnings_Mode_Off): Use the correct source file for
9354 Stop. Was using Current_Source_File, which is only valid during
9355 parsing. Current_Source_File will have a leftover value from
9356 whatever file happened to be parsed last, because of a with_clause
9359 2017-04-25 Bob Duff <duff@adacore.com>
9361 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
9362 to In_Predefined_Unit, but including GNAT units.
9363 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
9364 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
9365 because Should_Ignore_Pragma was not working reliably outside
9366 the parser, because Current_Source_File is not valid.
9367 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
9368 * par-prag.adb: Call Should_Ignore_Pragma_Par.

9437 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
9438 of prefix whose type is a current instance of a synchronized
9439 type. If the prefix is an object this is an external call (or
9440 requeue) that can only access public operations of the object. The
9441 previous predicate was too restrictive, and did not allow public
9442 protected operations, only task entries.
9444 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9446 * sem_ch5.adb, fname.adb: Minor reformatting.

9454 (Is_Anonymous_Access_Type): New routine.
9455 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
9456 master for an access type subject to pragma No_Heap_Finalization.
9457 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
9458 allocated or deallocated does not finalization actions if the
9459 associated access type is subject to pragma No_Heap_Finalization.
9460 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
9461 * par-prag.adb Pragma No_Heap_Finalization does not need special
9462 processing from the parser.
9463 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
9464 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
9465 * sem_prag.adb Add an entry in table Sig_Flags for pragma
9466 No_Heap_Finalization.
9467 (Analyze_Pragma): Add processing for

9476 * freeze.adb (Freeze_Record_Type): Use the
9477 underlying type of the component type to determine whether it's
9478 elementary. For representation clause purposes, a private type
9479 should behave the same as its full type.
9480 * fname.ads, fname.adb (Is_Predefined_File_Name):
9481 Make sure things like "system.ali" are recognized as predefined.
9483 2017-04-25 Javier Miranda <miranda@adacore.com>

9495 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
9496 Is_Internal_Unit_Name): New functions for operating on unit
9497 names, as opposed to file names. There's some duplicated code
9498 with fname.adb, which is unfortunate, but it seems like we don't
9499 want to add dependencies here.
9500 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
9501 to Is_Predefined_Unit_Name; the former was wrong, because Uname
9502 is not a file name at all.
9503 * fname.ads, fname.adb: Document the fact that
9504 Is_Predefined_File_Name and Is_Internal_File_Name can be called
9505 for ALI files, and fix the code so it works properly for ALI
9506 files. E.g. these should return True for "system.ali".
9508 2017-04-25 Justin Squirek <squirek@adacore.com>
9510 * exp_util.adb (Add_Invariant): Removed,
9511 code moved to Add_Invariant_Check, Add_Inherited_Invariant,

9523 relavant code was inlined into both Add_Own_Invariant and
9524 Add_Inherited_Invariant.

9550 (Replace_Type_References):
9551 Append an extra parameter to allow for dispatching replacements
9552 and add the corrasponding logic.

9555 Replace_Type_References.
9556 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.

9563 when compiling predefined files.
9564 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
9565 "gnat.adc" should not be considered a predefined file name.
9566 That required (or at least encouraged) a lot of cleanup of global
9567 variable usage. We shouldn't be communicating information via
9568 the global name buffer.
9569 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
9570 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

9669 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
9670 DIC pragma is placed at the top of a declarative region.
9672 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

9680 the error message when the attribute reference is an actual in
9681 a call to a subprogram inherited from a generic formal type with
9682 unknown discriminants, which makes the subprogram and its formal
9683 parameters intrinsic (see RM 6.3.1 (8) and (13)).
9685 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9687 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

10436 2017-01-23 Claire Dross <dross@adacore.com>
10438 * exp_spark.adb (Expand_SPARK_Attribute_Reference): For
10439 attributes which return Universal_Integer, introduce a conversion
10440 to the expected type with the appropriate check flags set.
10441 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
10442 base type if the range is null. It may still be invalid if it

10459 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
10460 an object declaration for an array type with a modular index type
10461 with the size of Long_Long_Integer. Special processing is needed
10462 in this case to compute reliably the size of the object, and
10463 eventually to raise Storage_Error, when wrap-around arithmetic
10464 might compute a meangingless size for the object.
10466 2017-01-23 Justin Squirek <squirek@adacore.com>
10468 * a-wtenau.adb, par-endh.adb, sem_prag.adb,

10473 * sem_res.adb (Resolve_Call): In the part of the code where
10474 it is deciding whether to turn the call into an indexed
10475 component, avoid doing so if the call is to an instance of
10476 Unchecked_Conversion. Otherwise, the compiler turns it into an
10477 indexed component, and resolution of that turns it back into a
10478 function call, and so on, resulting in infinite recursion.
10479 * sem_util.adb (Needs_One_Actual): If the first formal has a
10480 default, then return False.

10582 returns a limited view of a type and at the point of the call the
10583 function is not declared in the extended main unit then replace
10584 it with the non-limited view, which must be available. If the
10585 called function is in the extended main unit then no action is
10586 needed since the back-end handles this case.

10916 * sem_util.adb (Unique_Name): for instances of
10917 generic subprograms ignore the name of the wrapper package.
10919 2017-01-19 Javier Miranda <miranda@adacore.com>
10921 * exp_aggr.adb (Resolve_Record_Aggregate):
10922 Factorize code needed for aggregates of limited and unlimited
10923 types in a new routine.
10924 (Pass_Aggregate_To_Back_End): New subprogram.
10926 2017-01-19 Yannick Moy <moy@adacore.com>
10928 * sinfo.adb (Pragma_Name): Only access up to Last_Pair of Pragma_Map.
10930 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10932 * sem_ch4.ads, sem_ch4.adb (Try_Object_Operation): Make subprogram
10933 public, for use elsewhere.
10934 * sem_ch6.adb (Analyze_Procedure_Call): In SPARK_Mode and within
10935 an Inlined_body, recognize a call that uses object notation
10936 and has not been rewritten as a regular call because regular
10937 expansion has not taken place.
10939 2017-01-19 Bob Duff <duff@adacore.com>
10941 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
10942 in case of generic formal discrete types, because it causes crashes in
10943 the compiler when built with assertions on.
10945 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
10947 * lib-xref-spark_specific.adb, sem_util.adb, sem_util.ads,
10948 sem_ch4.adb, sem_ch8.adb, lib-xref.ads: Minor reformatting.
10950 2017-01-19 Bob Duff <duff@adacore.com>
10952 * bcheck.adb (Check_Consistent_Dynamic_Elaboration_Checking):
10953 Increment Warnings_Detected. It was decrementing, which is
10954 wrong since we just issued a warning message.
10955 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
10956 these variables to be of subtype Nat instead of Int, because
10957 they should never be negative.
10959 2017-01-19 Javier Miranda <miranda@adacore.com>
10961 * contracts.adb (Build_Postconditions_Procedure): Replace
10962 Generate_C_Code by Modify_Tree_For_C.
10963 * exp_aggr.adb (Build_Record_Aggr_Code, Expand_Array_Aggregate):
10964 Replace Generate_C_Code by Modify_Tree_For_C.

10967 * exp_ch11.adb (Expand_N_Exception_Declaration): Replace
10968 Generate_C_Code by Modify_Tree_For_C.

10972 by Modify_Tree_For_C.
10973 * exp_util.adb (Remove_Side_Effects, Side_Effect_Free): Replace
10974 Generate_C_Code by Modify_Tree_For_C.
10975 * sem_res.adb (Resolve_Type_Conversion): Replace Generate_C_Code
10976 by Modify_Tree_For_C.
10977 * sinfo.ads (Modify_Tree_For_C): Adding documentation.
10979 2017-01-19 Javier Miranda <miranda@adacore.com>
10981 * sem_util.ads, sem_util.adb (Expression_Of_Expression_Function): New
10983 (Is_Inlinable_Expression_Function): New subprogram.
10984 * exp_ch6.ads, exp_ch6.adb (Expression_Of_Expression_Function): Moved
10986 (Is_Inlinable_Expression_Function): Moved to Sem_Util.
10988 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10990 * sem_ch4.adb (Diagnose_Call): Improve error message when a
10991 selected component has a prefix that might be interpreted
10992 as a parameterless function call, but none of the candidate
10993 interpretations is parameterless, and there is a hidden homonym
10994 of the prefix that is a package.
10995 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
10996 interpreted as a parameterless function call and its analysis
10997 fails, do not call Analyze_Selected_Component.
10999 2017-01-19 Steve Baird <baird@adacore.com>
11001 * sem_util.ads: Add new Use_Full_View Boolean parameter to
11003 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
11004 calls to a newly-defined Scalar_Range_Of_Right_View function.
11006 2017-01-19 Arnaud Charlet <charlet@adacore.com>
11008 * gnat1drv.adb: minor fix of unbalanced parens in comment
11009 * lib-xref.ads (Traverse_Compilation_Unit): declaration moved
11010 to visible part of the package to allow re-use in GNATprove.
11011 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
11012 from repeated code of Traverse_Compilation_Unit.
11013 (Traverse_Declaration_Or_Statement): fixed detection of
11014 generic subprograms and packages; also, iteration over case
11015 statement alternatives rewritten to avoid testing if the first
11016 alternative is present (since it must be present due to Ada
11017 syntax restrictions).
11019 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
11021 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as
11022 returning by reference not just for subprogram body stubs,
11023 but for all subprogram cases.
11024 * sem_util.adb: Code reformatting.
11025 (Requires_Transient_Scope): Update the call to Results_Differ.
11026 (Results_Differ): Update the parameter profile and the associated
11029 2017-01-19 Ed Schonberg <schonberg@adacore.com>
11031 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
11032 identifier nodes that do not come from source, to handle properly
11033 dimensionality check within an inlined body which inclddes both
11034 original operands and rewritten operands. This removes spurious
11035 dimensionality errors in the presence of front-end inlining,
11036 as well as in SPARK mode.
11038 2017-01-16 Jakub Jelinek <jakub@redhat.com>
11041 * gcc-interface/lang.opt (gant, gnatO, gnat): Add Driver flag.
11043 2017-01-13 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE>
11045 * gcc-interface/Makefile.in (SPARC/Solaris): Fix typo.

11074 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11076 * einfo.ads: minor grammar fixes in comment of Normalized_Position_Max.
11077 * scil_ll.adb: Minor style fix in comment.
11078 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
11079 even if entity is already set, because the node may be renalyzed
11080 after inlining transformations.
11082 2017-01-13 Javier Miranda <miranda@adacore.com>
11084 * sem_res.adb (Resolve_Call): Do not establish a transient scope
11085 for a call to inlinable expression function (since the call will
11086 be replaced by its returned object).
11087 * exp_ch6.ads (Is_Inlinable_Expression_Function): New subprogram.
11088 * exp_ch6.adb (Expression_Of_Expression_Function): New subprogram.
11089 (Expand_Call): For inlinable expression function call replace the
11090 call by its returned object.
11091 (Is_Inlinable_Expression_Function): New subprogram.
11093 2017-01-13 Gary Dismukes <dismukes@adacore.com>
11095 * checks.adb: Minor typo fix and reformatting.
11097 2017-01-13 Javier Miranda <miranda@adacore.com>
11099 * contracts.adb (Contract_Only_Subprograms): Remove formal.
11100 (Copy_Original_Specification): Removed.
11101 (Skip_Contract_Only_Subprogram): Move here checks previously
11102 located in the caller of this routine (to leave the code more clean).
11103 (Build_Contract_Only_Subprogram): Code cleanup.
11104 * scil_ll.ads, scil_ll.adb (Get_Contract_Only_Body_Name): Removed.
11105 (Get_Contract_Only_Missing_Body_Name): Removed.
11107 2017-01-13 Javier Miranda <miranda@adacore.com>
11109 * sem_ch6.adb (Cloned_Expression): New subprogram.
11110 (Freeze_Expr_Types): Complete previous patch since the expression
11111 of an expression-function may have iterators and loops with
11112 defining identifiers which, as part of the preanalysis of the
11113 expression, may be left decorated with itypes that will not be
11114 available in the tree passed to the backend.
11116 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11118 * checks.adb (Apply_Type_Conversion_Checks): Optimize a type
11119 conversion to Integer of an expression that is an attribute
11120 reference 'Pos on an enumeration type.
11122 2017-01-13 Bob Duff <duff@adacore.com>
11124 * atree.ads: Minor comment fix.
11126 2017-01-13 Justin Squirek <squirek@adacore.com>

11129 calls in accessibility check on return statement.
11131 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11133 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
11134 Ensure that the input body is a subprogram body before trying to
11135 determine whether it denoted an expression function. Note that
11136 subprogram body stubs cannot denote expression functions.
11138 2017-01-13 Gary Dismukes <dismukes@adacore.com>
11140 * bindgen.adb, sem_ch6.adb, binde.adb, exp_ch3.adb: Minor reformatting
11143 2017-01-13 Javier Miranda <miranda@adacore.com>
11145 * einfo.ads (Component_Bit_Offset): Fix documentation.
11146 * sem_ch13.adb (Check_Record_Representation_Clause): Skip check
11147 on record holes for components with unknown compile-time offsets.
11149 2017-01-13 Bob Duff <duff@adacore.com>
11151 * ali.ads, ali.adb (Static_Elaboration_Model_Used): Remove unused flag.
11152 * g-locfil.ads: Minor comment fix.
11154 2017-01-13 Bob Duff <duff@adacore.com>
11156 * binde.adb (Elab_New): New elaboration order algorithm
11157 that is expected to cause fewer ABE issues. This is a work in
11158 progress. The new algorithm is currently disabled, and can be
11159 enable by the -dp switch, or by modifying the Do_Old and Do_New
11160 etc. flags and rebuilding. Experimental code is included to
11161 compare the results of the old and new algorithms.
11162 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
11163 can have multiple of these tables, so the old and new algorithms
11165 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
11166 parameter of type array. This avoids the global variable, and
11167 allows bounds checking (which is normally defeated by the tables
11168 packages). It also ensures that the Elab_Order is read-only
11170 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
11171 subprograms that need it, as above.
11172 * debug.adb: Document new -dp switch. Modify doc of old -do
11174 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
11175 and Bindgen. Move writing of closure (-R and -Ra switches)
11176 to Binde; that's more convenient.
11178 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11180 * sem_ch6.adb (Analyze_Expression_Function): If the expression
11181 function is a completion, all entities referenced in the
11182 expression are frozen. As a consequence, a reference to an
11183 uncompleted private type from an enclosing scope is illegal.
11185 2017-01-13 Javier Miranda <miranda@adacore.com>
11187 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
11188 (Analyze_Subprogram_Body_Helper): At the occurrence of an
11189 expression function declaration that is a completion, its
11190 expression causes freezing (AI12-0103).
11192 2017-01-13 Vadim Godunko <godunko@adacore.com>
11194 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and
11195 Reference functions of Ada.Containers.Indefinite_Holders.
11197 2017-01-13 Bob Duff <duff@adacore.com>
11199 * s-os_lib.ads: Minor comment fixes.
11201 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11203 * exp_ch3.adb (Default_Initialize_Object): Do not default
11204 initialize an object when it is of a task type and restriction
11205 No_Tasking is in effect because the initialization is obsolete.
11206 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
11207 restriction No_Tasking is in effect.
11208 (Build_Master_Renaming): Do not rename a master when restriction
11209 No_Tasking is in effect.
11211 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11213 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
11214 the legality of An others clause applies as well to a choice in
11215 an Iterated_component_ association.
11216 (Resolve_Iterated_Component_Association): An others choice
11218 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
11219 Iterated_Component_Association is not static.
11221 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11223 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
11224 control is passed to the expresion handler before the new mode
11226 * sem_ch12.adb (Analyze_Package_Instantiation,
11227 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set
11228 in case control is passed to the expresion handler before the
11231 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11233 * sem_aggr.adb, sem_ch3.adb, inline.adb, sem_util.adb, exp_ch4.adb,
11234 exp_aggr.adb: Minor reformatting.
11236 2017-01-13 Gary Dismukes <dismukes@adacore.com>
11238 * inline.adb: Minor reformatting and typo fix.
11240 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11242 * sem_util.ads, sem_util.adb (Choice_List): Move function here
11243 from sem_aggr.adb, for use elsewhere.
11244 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
11245 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
11246 Iterated_Component_Present.
11247 * exp_aggr.adb: Use Choice_List throughout, to handle
11248 Iterated_Component_Associations.
11249 (Gen_Loop): Generate proper loop for an
11250 Iterated_Component_Association: loop variable has the identifier
11251 of the original association. Generate a loop even for a single
11252 component choice, in order to make loop parameter visible in
11254 (Flatten): An Iterated_Component_Association is not static.
11256 2017-01-13 Yannick Moy <moy@adacore.com>
11258 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
11259 float exponentiation for statically known small negative values
11260 is the reciprocal of the exponentiation for the opposite value
11262 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
11263 Ensure that the value of float exponentiation for negative values
11264 is the reciprocal of the exponentiation for the opposite value
11266 * inline.adb (Expand_Inlined_Call): Fix the count
11267 for the number of generated gotos.
11269 2017-01-13 Yannick Moy <moy@adacore.com>
11271 * inline.adb: Code cleanup.
11272 * sem_util.adb (Is_OK_Volatile_Context): Add
11273 expression in delay statement as OK for volatile context.
11275 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11277 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
11278 mode a choice that is a subtype with a static predicate is
11279 replaced by the values it covers. This transformation must not
11280 be performed in ASIS mode, to preserve the source for analysis.
11282 2017-01-13 Justin Squirek <squirek@adacore.com>
11284 * nlists.ads: Correct minor typo.
11286 2017-01-13 Gary Dismukes <dismukes@adacore.com>

11293 Iterated_Component_Association is a named association in an
11295 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
11296 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
11297 and resolve the discrete choices and the expression of the
11299 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
11300 Loop_Actions and Box_Present are attributes of
11301 N_Iterated_Component_Association nodes. Box_Present is always
11302 False in this case.
11303 * sprint.adb (Sprint_Node): An Iterated_Component_Association
11304 has a Discrete_Choices list, as specified in the RM. A
11305 Component_Association for aggregate uses instead a Choices list.
11306 We have to live with this small inconsistency because the new
11307 construct also has a defining identifier, and there is no way
11308 to merge the two node structures.
11310 2017-01-13 Yannick Moy <moy@adacore.com>
11312 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the
11313 list of pragmas to remove. Remove pragmas from the list of
11314 statements in the body to inline.
11315 * namet.adb, namet.ads (Nam_In): New version with 12 parameters.
11317 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11319 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
11320 Analyze_Declarations, to analyze and resolve the expressions of
11321 aspect specifications in the current declarative list, so that
11322 the expressions have proper entity and type info. This is needed
11323 for ASIS when there is no subsequent expansion to generate this
11324 semantic information.
11325 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
11326 original expression, to suppress cascaded errors when expression
11327 has been constant-folded.
11328 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
11329 ASIS mode, because there is no subsequent expansion to decorate
11332 2017-01-13 Yannick Moy <moy@adacore.com>
11334 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
11335 New function to detect when a call may be inlined or not in
11337 (Expand_Inlined_Call): Ensure that a temporary
11338 is always created in the cases where a type conversion may be
11339 needed on an input parameter in GNATprove mode, so that GNATprove
11340 sees the check to perform.
11341 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
11342 when not applicable due to actual requiring type conversion
11343 with possible check but no temporary value can be copied for
11344 GNATprove to see the check.
