71 bug causes a mismatch of build-in-place between caller and callee.
72 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
73 PE_Build_In_Place_Mismatch.

148 is available (Is_Verifiable_DIC_Pragma): Moved from Sem_Util.
149 * sem_util.adb (Has_Full_Default_Initialization):
150 Has_Fully_Default_Initializing_DIC_Pragma is now used to determine

157 (Is_Verifiable_DIC_Pragma): Moved to Exp_Util.
158 * sem_warn.adb (Is_OK_Fully_Initialized):
159 Has_Fully_Default_Initializing_DIC_Pragma is now used to determine
160 whether a type has full default initialization due to pragma
161 Default_Initial_Condition.
163 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
165 * sem_prag.adb (Match_Constituent): Do not quietly accept constants as

178 * exp_ch6.adb (Expand_N_Extended_Return_Statement,
179 Expand_Simple_Function_Return): Assert that the b-i-p-ness of the
180 caller and callee match. Otherwise, we would need some substantial
181 changes to allow b-i-p calls non-b-i-p, and vice versa.
183 2017-12-15 Ed Schonberg <schonberg@adacore.com>
185 * exp_unst.adb (Unnest_Subprograms): Nothing to do if the main unit is
186 a generic package body. Unnesting is only an issue when generating
187 code, and if the main unit is generic then nested instance bodies have
188 not been created and analyzed, and unnesting will crash in the absence
191 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
193 * inline.adb (Add_Inlined_Body): Do not add a function which is
194 completed by an expression function defined in the same context as the
195 initial declaration because the completing body is not in a package
197 (Is_Non_Loading_Expression_Function): New routine.
199 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
201 * debug.adb: Move the functionality of -gnatdL to -gnatd_i. Restore

203 * sem_elab.adb: Update the section of compiler switches.
204 (Build_Call_Marker): Do not create a marker for a call which originates
205 from an expanded spec or body of an instantiated gener, does not invoke
206 a generic formal subprogram, the target is external to the instance,
207 and -gnatdL is in effect.
208 (In_External_Context): New routine.
209 (Process_Conditional_ABE_Activation_Impl): Update the uses of -gnatdL
211 (Process_Conditional_ABE_Call): Update the uses of -gnatdL and

215 * exp_unst.adb: Minor typo fixes and edits.
217 2017-12-15 Ed Schonberg <schonberg@adacore.com>
219 * sem_ch6.adb (Possible_Freeze): Do not set Delayed_Freeze on an
220 subprogram instantiation, now that the enclosing wrapper package
221 carries an explicit freeze node. THis prevents freeze nodes for the
222 subprogram for appearing in the wrong scope. This is relevant when the
223 generic subprogram has a private or incomplete formal type and the
224 instance appears within a package that declares the actual type for the
225 instantiation, and that type has itself a delayed freeze.
227 2017-12-15 Patrick Bernardi <bernardi@adacore.com>
229 * doc/gnat_ugn/gnat_and_program_execution.rst: Removed references to
230 the environment variable GNAT_STACK_LIMIT from the Stack Overflow
231 Checking section as it is no longer used by any of our supported
234 2017-12-15 Bob Duff <duff@adacore.com>
236 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
237 Init_Assignment is rewritten, we need to set Assignment_OK on the new
238 node. Otherwise, we will get spurious errors when initializing via
239 assignment statement.
241 2017-12-15 Arnaud Charlet <charlet@adacore.com>
243 * exp_unst.adb (Visit_Node): Refine handling of 'Access to ignore non

251 (Truncation): Likewise.
253 2017-12-15 Bob Duff <duff@adacore.com>
255 * exp_ch7.adb (Expand_Cleanup_Actions): Make sure the block and handled
256 statement sequence generated for certain extended return statements
257 have a Sloc that is not No_Location. Otherwise, the back end doesn't
258 set any location and ends up reading uninitialized variables.
260 2017-12-15 Bob Duff <duff@adacore.com>
262 * types.ads, exp_ch6.adb, libgnat/s-regexp.ads, opt.ads: Partly revert
263 r255414, committed by mistake.

276 to 0 on the callee if the call is recursive.
278 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
280 * gcc-interface/decl.c (gnat_to_gnu_field): Do not set the alignment
281 of the enclosing record type if it is not already set.
283 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
285 * gcc-interface/gigi.h (pad_type_has_rm_size): Declare.
286 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Do not build
287 a padding type for the alignment before validating the size.
288 Flip conditional construct and add a comment.
289 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Size>: Make sure to
290 apply the exception for padded objects to the type of the object.
291 * gcc-interface/utils.c (hash_pad_type): New static function.
292 (lookup_and_insert_pad_type): Rename into...
293 (canonicalize_pad_type): ...this. Call hash_pad_type, do only one
294 lookup with insertion and always return the canonical type.
295 (maybe_pad_type): Adjust to above changes. Set debug type later.
296 (pad_type_has_rm_size): New predicate.
297 (set_reverse_storage_order_on_pad_type): Adjust to above changes.

311 descendant of System.Address.
312 (gnat_to_gnu_subprog_type): Likewise.
314 2017-12-08 Jakub Jelinek <jakub@redhat.com>
316 * gcc-interface/utils.c (gnat_internal_attribute_table): Add
317 exclusions to the comment.
319 2017-12-07 Martin Sebor <msebor@redhat.com>

342 * exp_unst.ads: Fix typos.
344 2017-12-05 Jerome Lambourg <lambourg@adacore.com>
346 * libgnarl/s-taprop__qnx.adb: Better detect priority ceiling bug in
347 QNX. At startup, the first mutex created has a non-zero ceiling
348 priority whatever its actual policy. This makes some tests fail
349 (c940013 for example).
351 2017-12-05 Bob Duff <duff@adacore.com>
353 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Call
354 Expand_Cleanup_Actions for N_Extended_Return_Statement.
355 * exp_ch7.adb (Expand_Cleanup_Actions): Handle
356 N_Extended_Return_Statement by transforming the statements into a
357 block, and (indirectly) calling Expand_Cleanup_Actions on the block.
358 It's too hard for Expand_Cleanup_Actions to operate directly on the
359 N_Extended_Return_Statement, because it has a different structure than
360 the other node kinds that Expand_Cleanup_Actions.
361 * exp_util.adb (Requires_Cleanup_Actions): Add support for
362 N_Extended_Return_Statement. Change "when others => return False;" to
363 "when others => raise ...;" so it's clear what nodes this function
364 handles. Use named notation where appropriate.
365 * exp_util.ads: Mark incorrect comment with ???.
367 2017-12-05 Javier Miranda <miranda@adacore.com>
369 * exp_ch9.adb (Install_Private_Data_Declarations): Add missing

387 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
389 * rtsfind.ads: Add new enumeration literals: RE_Clock_Time (for
390 Ada.Real_Time.Clock_Time) and RO_CA_Clock_Time (for
391 Ada.Calendar.Clock_Time).
393 2017-12-05 Ed Schonberg <schonberg@adacore.com>
395 * sem_ch4.adb (Is_Private_Overriding): If the candidate private
396 subprogram is overloaded, scan the list of homonyms in the same
397 scope, to find the inherited operation that may be overridden
399 * exp_ch11.adb, exp_ch7.adb: Minor reformatting.
401 2017-12-05 Bob Duff <duff@adacore.com>
403 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
404 Init_Assignment is rewritten, we need to set Assignment_OK on the new
405 node. Otherwise, we will get spurious errors when initializing via
406 assignment statement.
408 2017-12-05 Hristian Kirtchev <kirtchev@adacore.com>
410 * sem_elab.adb: Update the terminology and switch sections.
411 (Check_SPARK_Model_In_Effect): New routine.

420 2017-12-05 Nicolas Setton <setton@adacore.com>
422 * terminals.c (__gnat_setup_child_communication): As documented,
423 __gnat_setup_child_communication should not terminate - it is intended
424 to be used as the child process of a call to fork(). However, execvp
425 might actually return in some cases, for instance when attempting to
426 run a 32-bit binary on a 64-bit Linux distribution when the
427 compatibility packages are not installed. In these cases, exit the
428 program to conform to the documentation.

504 phase. Resurrect the previous elaboration model as "legacy elaboration
506 (Build_Call_Marker): This routine does not function when the legacy
507 elaboration model is in effect. Do not consider entry calls and requeue
508 statements when debug flag d_e is in effect. Do not consider calls to
509 subprograms which verify the runtime semantics of certain assertion
510 pragmas when debug flag d_p is in effect.
511 (Build_Variable_Reference_Marker): This routine does not function when
512 the legacy elaboration model is in effect.
513 (Check_Elaboration_Scenarios): This routine does not function when the
514 legacy elaboration model is in effect.
515 (Ensure_Prior_Elaboration): The various flags have now been replaced
516 with a state. Do not generate implicit Elaborate[_All] pragmas when
517 their creation has been suppressed.

519 the requested pragma, not on the nature of the scenario.
520 (In_External_Context): Removed.
521 (Is_Assertion_Pragma_Target): New routine.
522 (Is_Potential_Scenario): Stop the traversal of a task body when
523 reaching an accept or select statement, and debug switch d_a is in

1104 that fails when Make_Independent is called on a user task.

1155 2017-11-09 Pascal Obry <obry@adacore.com>
1157 * libgnarl/s-taprop__mingw.adb: On Windows, initialize the thead handle
1158 only for foreign threads. We initialize the thread handle only if not
1159 yet initialized. This happens in Enter_Task for foreign threads only.
1160 But for native threads (Ada tasking) we do want to keep the real
1161 handle (from Create_Task) to be able to free the corresponding
1162 resources in Finalize_TCB (CloseHandle).
1164 2017-11-09 Yannick Moy <moy@adacore.com>

1175 dispatch table is statically built.
1176 (Make_DT): Declare constant the Interface_Table object associated with
1177 an statically built dispatch table. For this purpose the Offset_To_Top
1178 value of each interface is computed using the dummy object.

1180 the Offset_To_Top field of secondary dispatch tables when the dispatch
1181 table is statically built.

1191 to avoid a dormant bug.
1193 2017-11-09 Jerome Lambourg <lambourg@adacore.com>
1195 * init.c: Define missing __gnat_alternate_stack for QNX. Set it to 0,
1196 as such capability is not available on the OS.
1197 * link.c: Make sure linker options for QNX are correct.
1198 * libgnarl/s-osinte__qnx.ads: Add some missing bindings to pthread.
1199 * libgnarl/s-taprop__qnx.adb: New, derived from s-taprop__posix.adb. This brings
1200 in particular a workaround with locks priority ceiling where a higher
1201 priority task is allowed to lock a lower ceiling priority lock. This
1202 also fixes the scheduling of FIFO tasks when the priority of a task is
1204 * libgnat/system-qnx-aarch64.ads: Fix priority ranges.
1206 2017-11-09 Yannick Moy <moy@adacore.com>
1208 * erroutc.adb (Output_Error_Msgs): Justify CodePeer false positive
1210 * gnatbind.adb (Scan_Bind_Arg): Simplify test to remove always true
1212 * namet.adb (Copy_One_Character): Add assumption for static analysis,
1213 as knowledge that Hex(2) is in the range 0..255 is too complex for
1215 (Finalize): Add assumption for static analysis, as the fact that there
1216 are symbols in the table depends on a global invariant at this point in
1218 * set_targ.adb (Check_Spaces): Justify CodePeer false positive message.
1219 * stylesw.adb (Save_Style_Check_Options): Rewrite to avoid test always
1222 2017-11-09 Javier Miranda <miranda@adacore.com>
1224 * libgnat/s-rident.ads (Static_Dispatch_Tables): New restriction name.
1225 * exp_disp.adb (Building_Static_DT): Check restriction.
1226 (Building_Static_Secondary_DT): Check restriction.
1227 (Make_DT): Initialize the HT_Link to No_Tag.
1228 * opt.ads (Static_Dispatch_Tables): Rename flag...

1262 * exp_util.adb (Find_Interface_Tag): Default initialize AI_Tag.
1263 * freeze.adb (Check_Component_Storage_Order): Default initialize
1264 Comp_Byte_Aligned rather than silencing messages with pragma
1265 Warnings(Off), which does not work for CodePeer initialization
1266 messages, and given that here the possible read of an unitialized value
1267 depends on a proper use of parameters by the caller.
1268 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.
1269 * sem_ch12.adb (Build_Operator_Wrapper): Default initialize Expr.
1270 * sem_ch3.adb (Build_Derived_Array_Type): Default initialize

1273 pragma Warnings(Off).
1274 (Analyze_Case_Expression): Rescope checking block within branch where
1275 Others_Present is set by the call to Check_Choices.
1276 * sem_ch5.adb (Analyze_Assignment): Default initialize
1278 * sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,
1279 and restructure code to defend against previous errors, so that, in
1280 that case, control does not flow to the elsif condition which read an
1281 uninitialized Obj_Decl.
1282 * sem_ch9.adb (Analyze_Requeue): Default initialize Synch_Type.
1283 (Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
1284 which seem to be left uninitialized and possibly read in some cases.
1285 * sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more
1286 precisely. This requires to exchange the test for exiting in case of
1287 too many positions and the increment to Position, inside the loop.
1288 * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,
1289 which cannot be read uninitialized, but the reasons for that are quite
1291 * sem_intr.adb (Check_Intrinsic_Call): Default initialize Rtyp.
1292 * sem_prag.adb (Collect_Subprogram_Inputs_Outputs): Default initialize
1294 * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
1295 and test for presence of non-null Opnd_Type before testing its scope,
1296 in a test which would read its value uninitialized, and is very rarely
1297 exercized (it depends on the presence of an extension of System).
1298 * sem_spark.ads: Update comment to fix name of main analysis procedure.
1299 * sem_warn.adb (Warn_On_Known_Condition): Default initialize
1301 * set_targ.adb (FailN): Mark procedure with No_Return.
1302 * stylesw.adb (Save_Style_Check_Options): Delete useless code to
1303 initialize all array Options to white space, as there is already code
1304 doing the same for the remaining positions in Options at the end of the
1307 2017-11-09 Eric Botcazou <ebotcazou@adacore.com>
1309 * exp_ch11.adb (Possible_Local_Raise): Do not issue the warning for

1314 * sem_prag.adb (Analyze_Part_Of): Reword error message.
1315 (Get_SPARK_Mode_Type): Do not raise Program_Error in case pragma

1321 * sem_ch4.adb (Analyze_Call): Reject a call to a function that returns
1322 a limited view of a type T declared in unit U1, when the function is
1323 declared in another unit U2 and the call appears in a procedure within

1328 * sem_ch8.adb (Analyze_Use_Package): Force installation of use_clauses
1329 when processing generic instances.
1331 2017-11-09 Bob Duff <duff@adacore.com>
1333 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
1334 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
1335 objects can have those special values. Valid_Name_Id could usefully be
1336 used all over the compiler front end, but that's too much trouble for
1337 now. If we did that, we might want to rename:
1338 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
1339 For parameters of type Valid_Name_Id, remove some redundant tests,
1340 including the ones found by CodePeer. Use Is_Valid_Name instead of
1341 membership test when appropriate.
1342 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
1343 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
1344 "in Error_Name_Or_No_Name".
1345 (Check_Parameterless_Call): Use "not Is_Valid_Name" instead of "in
1346 Error_Name_Or_No_Name".

1351 mode here unless -gnateC is specified.

1357 * lib-writ.adb (Write_ALI): Remove processing of the frontend xrefs as
1358 part of the ALI writing; they are now processed directly from memory
1359 when requested by the backend.

1406 * sem_res.adb (Resolve): If expression is an entity whose type has
1407 implicit dereference, generate reference to it, because no reference is
1408 generated for an overloaded entity during analysis, given that its
1409 identity may not be known.
1411 2017-11-09 Javier Miranda <miranda@adacore.com>

1414 offset-to-top field by addition.
1415 (Make_Secondary_DT): Initialize the offset-to-top field with a negative

1418 return a negative offset-to-top value.
1419 (Initialize_Tag): Invoke runtime services Set_Dynamic_Offset_To_Top and
1420 Set_Static_Offset_To_Top passing a negative offet-to-top value;
1421 initialize also the offset-to-top field with a negative offset.
1422 * libgnat/a-tags.adb (Base_Address): Displace the pointer by means of
1423 an addition since the offset-to-top field is now a negative value.
1424 (Displace): Displace the pointer to the object means of a substraction
1425 since it is now a negative value.
1426 (Set_Dynamic_Offset_to_top): Displace the pointer to the object by

2740 * sem_util.adb (Object_Access_Level): If the object is the return
2741 statement of an expression function, return the level of the function.
2742 This is relevant when the object involves an implicit conversion
2743 between access types and the expression function is a completion, which
2744 forces the analysis of the expression before rewriting it as a body, so
2745 that freeze nodes can appear in the proper scope.

2770 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking

2774 as for the other Is_B-I-P... functions.

2782 internally-generated call.

2787 implies >= Ada 2005.

2817 a freeze node for the instance of the parent if it appears in the same
2818 scope and is not frozen yet.
2820 2017-10-09 Pierre-Marie de Rodat <derodat@adacore.com>
2822 * exp_atag.ads, libgnat/a-tags.adb, libgnat/a-tags.ads: Enhance

2825 2017-10-09 Bob Duff <duff@adacore.com>
2827 * exp_ch3.adb (Build_Assignment): Parameter name N was somewhat
2828 confusing. Same for N_Loc. Remove assumption that b-i-p implies
2829 limited. This is for the case of a function call that occurs as the
2830 default for a record component.
2831 (Expand_N_Object_Declaration): Deal with the case where expansion has
2832 created an object declaration initialized with something like

2840 object itself must be retrieved when generating the range test that
2841 implements the validity check on a scalar type.

2902 (Is_Build_In_Place_Result_Type): New function to accompany
2903 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
2904 sometimes we just have the type on our hands, not the function. For
2905 now, does the same thing as the old version, so build-in-place is
2906 disabled for nonlimited types, except that you can use -gnatd.9 to
2908 * exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
2909 accompany Is_Build_In_Place_Function and

2923 an unchecked conversion. Add assertions.

3983 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
3986 2017-09-08 Bob Duff <duff@adacore.com>
3988 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
3989 Ada_2020, along the same lines as the other Ada version pragmas.
3991 2017-09-08 Gary Dismukes <dismukes@adacore.com>
3993 * sem_ch12.adb: Minor typo fixes and reformatting.
3995 2017-09-08 Yannick Moy <moy@adacore.com>
3997 * sem_aggr.adb (Resolve_Record_Aggregate):
3998 Rewrite bounds of aggregate subexpressions which may depend on
3999 discriminants of the enclosing aggregate.
4001 2017-09-08 Yannick Moy <moy@adacore.com>
4003 * sem_ch5.adb: Prevent assertion failure on illegal code.
4005 2017-09-08 Yannick Moy <moy@adacore.com>
4007 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
4008 calling Renamed_Entity on an entity which cannot be a renaming.
4010 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4012 * exp_aggr.adb: Add with & use clause for Urealp.
4013 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
4014 elementary types instead of just discrete types.
4015 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
4016 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
4017 Be prepared for the FP zero value in the memset case. Add small
4020 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4022 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
4025 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4027 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
4028 of New_Copy because the latter leaves the syntactic structure of
4029 the tree inconsistent (a child is accessible through two parents)
4030 and prevents proper replication of itypes by subsequent calls
4032 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
4033 New_Copy because the latter leaves the syntactic structure of the
4034 tree inconsistent (a child is accessible through two parents)
4035 and prevents proper replication of itypes by subsequent calls
4037 * sem_util.adb (In_Subtree): New routine.
4038 (New_Copy_Tree): Reimplemented.
4039 * sem_util.ads (In_Subtree): New routine.
4040 (New_Copy_Tree): Reimplemented.
4042 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4044 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
4045 for aspect Default_Value is a static scalar value, but it does
4046 not freeze the type. Yhis allows for subsequent representation
4047 clauses for the type.
4049 2017-09-08 Javier Miranda <miranda@adacore.com>
4051 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
4052 not add entries into the undefined reference table when we are
4053 compiling with errors ignored.
4055 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4057 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
4058 check if the instance is within an enclosing instance body. The
4059 formal package was legal in the enclosing generic, and is
4060 legal in the enclosing instantiation. This optimisation may be
4061 applicable elsewhere, and it also removes spurious errors that
4062 may arise with on-the-fly processing of instantiations that
4063 contain Inline_Always subprograms.
4065 2017-09-08 Vincent Celier <celier@adacore.com>
4067 * gnatcmd.adb: Disregard empty argument of GNAT driver.
4069 2017-09-08 Justin Squirek <squirek@adacore.com>
4071 * checks.adb (Insert_Valid_Check): Manually decorate
4072 the generated temporary for range valdity checks.
4074 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4076 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
4078 2017-09-08 Justin Squirek <squirek@adacore.com>
4080 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
4081 case to handle underscore flags.
4082 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
4083 new procedure to handle underscores.
4085 2017-09-08 Javier Miranda <miranda@adacore.com>
4087 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
4088 divisions with fixed point results to avoid generating twice
4089 the runtime check on divide by zero.
4090 * checks.adb (Apply_Divide_Checks): Ensure that operands are
4091 not evaluated twice (once for their runtime checks and once for
4092 their regular computation).
4094 2017-09-08 Yannick Moy <moy@adacore.com>
4096 * sem_prag.adb (Analyze_Part_Of): Add missing
4097 return statements after issuing errors. Add detection of
4098 out-of-order item and single concurrent type.

4228 when the actual is a construct that involves a dereference of an
4229 expression that includes a formal of the enclosing subprogram,
4230 In such cases, the accessibility level of the actual is that of
4231 the corresponding formal, which is passed in as an additional

4242 exceptions instead of crashes. Check for absurdly long strings
4243 and empty strings. Empty strings cause trouble because they can
4244 have super-null ranges (e.g. 100..10), which causes Ext_Copy to
4245 be empty, which causes an array index out of bounds.

4307 under -gnat2020 flag, given that it is a future feature of
4309 * sem_aggr.adb (Resolve_Iterated_Component_Association): Mark
4310 defining identifier as referenced to prevent spurious warnings:
4311 corresponding loop is expanded into one or more loops whose

4313 and not the original one.

4408 * exp_ch4.adb (Expand_Allocator_Expression): Invoke the new
4409 subprogram Make_Build_In_Place_Iface_Call_In_Allocator.

4422 * exp_disp.adb (Expand_Interface_Conversion): Fix handling of
4423 access to interface types. Remove also the accessibility check.
4425 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4427 * sem_ch6.adb (Freeze_Expr_Types): Really freeze
4428 all the types that are referenced by the expression.
4429 (Analyze_Expression_Function): Call Freeze_Expr_Types for
4430 a completion instead of manually freezing the type of the
4432 (Analyze_Subprogram_Body_Helper): Do not call Freeze_Expr_Types here.
4434 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4436 * exp_prag.adb (Replace_Discriminals_Of_Protected_Op):
4437 New procedure, auxiliary to Expand_Pragma_Check, to handle
4438 references to the discriminants of a protected type within a
4439 precondition of a protected operation. This is needed because
4440 the original precondition has been analyzed in the context of
4441 the protected declaration, but in the body of the operation
4442 references to the discriminants have been replaved by references
4443 to the discriminants of the target object, and these references
4444 are only created when expanding the protected body.
4446 2017-09-08 Yannick Moy <moy@adacore.com>
4448 * sem_prag.adb (Analyze_Pragma): Issue more precise error messages on
4451 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4453 * exp_attr.adb (Build_Record_VS_Func): If the record is an
4454 unchecked union, do not emit checks for its (non-existent)
4455 discriminants, or for variant parts that depend on them.
4457 2017-09-08 Justin Squirek <squirek@adacore.com>
4459 * sem_ch4.adb (Find_Equality_Types.Try_One_Interp,
4460 Find_Comparison_Type.Try_One_Interp): Add check for generic
4463 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4465 * sem_ch3.adb, layout.adb, layout.ads, exp_attr.adb, debug.adb,
4466 exp_pakd.adb, sem_prag.adb, gnat1drv.adb, targparm.adb, targparm.ads,
4467 repinfo.adb, exp_ch6.adb, exp_aggr.adb, sem_eval.adb, sem_ch13.adb,
4468 exp_ch3.adb: Remove references to Frontend_Layout_On_Target and
4469 remaining references to AAMP_On_Target.
4471 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4473 * style.adb: Fix typo.
4475 2017-09-08 Javier Miranda <miranda@adacore.com>
4477 * einfo.adb (Underlying_Type): Add missing support for class-wide
4478 types that come from the limited view.
4479 * exp_attr.adb (Attribute_Address): Check class-wide type
4480 interfaces using the underlying type to handle limited-withed
4482 (Attribute_Tag): Check class-wide type interfaces using
4483 the underlying type to handle limited-withed types.
4485 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4487 * exp_ch5.adb (Expand_Predicated_Loop): Handle properly a loop
4488 over a subtype of a type with a static predicate, taking into
4489 account the predicate function of the parent type and the bounds
4490 given in the loop specification.
4491 * sem_ch3.adb (Inherit_Predicate_Flags): For qn Itype created for
4492 a loop specification that is a subtype indication whose type mark
4493 is a type with a static predicate, inherit predicate function,
4494 used to build case statement for rewritten loop.
4496 2017-09-08 Justin Squirek <squirek@adacore.com>
4498 * lib-load.adb: Modify printing of error message to exclude file
4501 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4503 * inline.adb (Can_Be_Inlined_In_GNATprove_Mode):
4504 don't inline subprograms declared in both visible and private
4506 (In_Package_Spec): previously In_Package_Visible_Spec; now
4507 detects subprograms declared both in visible and private parts
4510 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4512 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
4513 the type is an anonymous array in an object declaration, whose
4514 component type has an invariant, use the object declaration
4515 as the insertion point for the invariant procedure, given that
4516 there is no explicit type declaration for an anonymous array type.
4518 2017-09-08 Bob Duff <duff@adacore.com>
4520 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.
4522 2017-09-08 Bob Duff <duff@adacore.com>
4524 * a-strfix.adb (Trim): Compute Low and High only if needed.
4526 2017-09-08 Justin Squirek <squirek@adacore.com>
4528 * lib-load.adb (Load_Main_Source): Add error output in the case a
4529 source file is missing.
4531 2017-09-08 Bob Duff <duff@adacore.com>
4534 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
4535 Default_WCEM by default (i.e. if the encoding is not specified
4536 by the Form string).
4538 2017-09-08 Bob Duff <duff@adacore.com>
4540 * s-trasym.ads (Hexa_Traceback): If
4541 Suppress_Hex is True, print "..." instead of a hexadecimal
4543 * s-trasym.adb: Ignore No_Hex in this version.
4546 2017-09-08 Bob Duff <duff@adacore.com>
4548 * debug.adb: Minor reformatting.
4550 2017-09-08 Bob Duff <duff@adacore.com>
4552 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
4553 code so it doesn't trigger an "uninit var" warning.
4555 2017-09-08 Nicolas Roche <roche@adacore.com>
4557 * s-hibaen.ads: Remove obsolete file.
4559 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4561 * a-locale.ads: Add comment explaining the state of this package.
4563 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4565 * sem_util.adb (Is_CCT_Instance): Allow calls in the context
4567 * sem_prag.ads, sem_prag.adb (Find_Related_Declaration_Or_Body):
4568 allow calls in the context of package spec (for pragma
4569 Initializes) and bodies (for pragma Refined_State).
4571 2017-09-08 Bob Duff <duff@adacore.com>
4573 * checks.adb (Insert_Valid_Check): Copy the Do_Range_Check flag to the
4576 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4578 * debug.adb (dA): Adjust comment.
4579 * gnat1drv.adb (Gnat1drv): Likewise.
4580 * opt.ads (List_Representation_Info_Extended): New variable.
4581 * repinfo.adb (List_Record_Info): Split implementation into...
4582 (Compute_Max_Length): ...this. Recurse on records if requested.
4583 (List_Record_Layout): Likewise.
4584 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
4585 statement, accept '0' and set List_Representation_Info_Extended
4587 * usage.adb (Usage): Document new -gnatRe variant.
4589 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4591 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
4592 Do not save the given entity in the global variable Default_Pool
4593 if the pragma appears within a generic unit.
4595 2017-09-08 Bob Duff <duff@adacore.com>
4597 * errout.adb (Delete_Warning): Do not
4598 decrement Warnings_Treated_As_Errors. This is called before
4599 Warnings_Treated_As_Errors has been incremented to account for
4600 this warning. Decrementing it here can lead to negative values
4601 of Warnings_Treated_As_Errors, raising Constraint_Error in
4602 checks-on builds, and causing the compiler to return an error
4603 code in checks-off builds.
4605 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4607 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
4608 entities of named concurrent types as Ref_Id and not of anonymous
4609 concurrent objects (because callers already know when a conversion
4610 is necessary and can easily do it); also, do not expect protected
4611 types or protected objects as Context_Id (because no flow-related
4612 SPARK pragmas are attached there); reflect these changes in a
4613 more precise comment.
4615 2017-09-08 Olivier Hainque <hainque@adacore.com>
4617 * g-altive.ads: Add documentation.
4619 2017-09-08 Bob Duff <duff@adacore.com>
4621 * sem_util.ads, debug.adb: Minor comment fix.
4622 * erroutc.ads: Comment fix.
4624 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4626 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
4627 for compatibility of component types of formal and actual in an
4628 instantiation of a child unit, when the component type of the
4629 formal is itself a formal of an enclosing generic.
4631 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4633 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
4634 sem_prag.adb to make it available for GNATprove; for concurrent
4635 types replace custom scope climbing with Scope_Same_Or_Within; for
4636 single concurrent objects add scope climbing (with Scope_Within),
4637 which was not there (that's the primary semantic change of this
4638 commit); also, when comparing a single concurrent object with
4639 its corresponding concurrent type rely on equality of types,
4640 not of objects (because that's simpler to code).
4641 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
4642 (Analyze_Global_Item): adjust special-casing of references to the
4643 current instance of a concurrent unit in the Global contracts
4644 of task types and single tasks objects; similar for references
4645 in the protected operations and entries of protected types and
4646 single protected objects (in all these cases the current instance
4647 behaves as an implicit parameter and must not be mentioned in
4648 the Global contract).
4650 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4652 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
4653 function calls returning a record within a subprogram call,
4656 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4658 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
4659 name that designates the current instance of a child unit in its
4660 own body and appears as the prefix of a reference to an entity
4661 local to the child unit.
4662 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
4665 2017-09-08 Yannick Moy <moy@adacore.com>

4672 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
4673 warnings on internal units in configurable run time mode.
4675 2017-09-08 Bob Duff <duff@adacore.com>
4677 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
4678 representation items from interfaces that the derived type
4679 implements, not just from the parent type.
4680 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
4681 this to return an empty list when there are no interfaces.
4682 * einfo.ads, sem_ch13.adb: Minor comment fixes.
4683 * sem_attr.adb: Minor comment fix.
4685 2017-09-08 Doug Rupp <rupp@adacore.com>
4687 * sigtramp-vxworks.c [i386]: Adjust the kernel context for
4690 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4692 * exp_ch4.adb (Expand_N_Allocator): Generate a
4693 call to Allocate_Any_Controlled when the allocation does not
4694 require any initialization.
4696 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4698 * sem_util.adb (Copy_Node_With_Replacement):
4699 Update the Renamed_Object field of a replicated object renaming
4702 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
4704 * exp_ch9.adb (Is_Pure_Barrier): Allow type
4705 conversions and components of objects. Simplified the detection
4706 of the Count attribute by identifying the corresponding run-time
4709 2017-09-08 Yannick Moy <moy@adacore.com>
4711 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
4712 sem_type.adb, sinfo.ads: Minor reformatting.
4714 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4716 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
4717 of Freeze_Profile, used to inhibit the freezing of the profile
4718 of an expression function declared within a nested package, when
4719 some type in the profile depends on a private type declared in
4720 an enclosing package.
4722 2017-09-08 Bob Duff <duff@adacore.com>
4724 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
4725 the subunit case. It's still OK to set it in the "missing subunits"
4726 case, because that won't cause the obsolete .ali files that cause
4729 2017-09-08 Bob Duff <duff@adacore.com>
4731 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
4732 unclear why this didn't cause a warning.
4733 * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
4734 pragmas. It's unclear why this didn't cause an error.
4736 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4738 * exp_spark.adb (Expand_SPARK_N_Object_Renaming_Declaration):
4740 (Expand_SPARK_Potential_Renaming): Code clean up.
4741 * sem_prag.adb (Analyze_Initialization_Item): Add a guard in case
4742 the item does not have a proper entity.

4760 * repinfo.adb (List_Record_Info): During first loop,
4761 do not override the normalized position and first bit
4762 if they have already been set. Move fallback code
4763 for the packed case to the case where it belongs.
4764 * sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
4765 Also adjust the normalized position of components.
4766 (Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise.
4768 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4770 * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
4771 the placement of a primitive operation O that renames an operation
4772 R declared in an inner package, and which is thus not a primitive
4773 of the dispatching type of O. In this case O is a new primitive
4774 and does not inherit its dispatch table position from R (which

4779 * sem_dim.adb (Analyze_Dimension_If_Expression,
4780 Analyze_Dimension_Case_Expression): new subprograms to verify
4781 the dimensional correctness of Ada2012 conditional expressions,
4782 and set properly the dimensions of the construct.
4783 * sem_res.adb (Resolve_If_Expression, Resolve_Case_Expression)):
4784 call Analyze_Dimension.
4786 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4788 * sem_type.adb (Expand_Interface_Conversion): Prevent an infinite
4789 loop on an interface declared as a private extension of another
4790 synchronized interface.

4794 * sem_ch12.adb (Check_Generic_Parent): New procedure within
4795 Analyze_Associations, to handle actual packages that depend on
4796 previous instances. If a package IAP that is an instantiation is
4797 used as an actual in a subsequent instantiation SI in the same
4798 scope, and IAP has a body, IAP must be frozen before SI. If
4799 the generic parent of IAP is itself declared in a previous
4800 instantiation in the same scope, that instantiation must also
4801 be frozen before SI.
4802 (Install_Body): Prevent double insertion of freeze node for
4805 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4807 * sem_prag.adb (Resolve_State): Update the

4813 * sem_ch13.adb (Analyze_Aspect_Specifications, case
4814 Linker_Section): If the aspect applies to an object declaration
4815 with explicit initialization, do not delay the freezing of the
4816 object, to prevent access-before-elaboration in the generated
4817 initialization code.
4819 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4821 * a-wtdeio.adb (Put, all versions): Use Long_Long_Integer
4822 (Integer_Value (Item)) when the size of the fixed decimal type
4823 is larger than Integer.
4825 2017-09-07 Eric Botcazou <ebotcazou@adacore.com>
4828 * gcc-interface/decl.c (copy_and_substitute_in_layout): Put the fields
4829 in order of increasing position in more cases.
4831 2017-09-07 Yannick Moy <moy@adacore.com>

4854 2017-09-07 Javier Miranda <miranda@adacore.com>
4856 * exp_disp.adb (Make_Tags): Avoid suffix counter
4857 in the external name of the elaboration flag. Required to fix
4858 the regressions introduced by the initial version of this patch.
4860 2017-09-07 Bob Duff <duff@adacore.com>
4862 * sem_ch6.adb (Analyze_Function_Return): Do not
4863 insert an explicit conversion to force the displacement of the
4864 "this" pointer to reference the secondary dispatch table in the
4865 case where the return statement is returning a raise expression,
4866 as in "return raise ...".
4868 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4870 * sem_disp.adb (Is_User_Defined_Equality): Removed procedure.

4889 * sem_dim.adb (Analyze_Dimension_Type_Conversion): New procedure
4890 to handle properly various cases of type conversions where the
4891 target type and/or the expression carry dimension information.
4892 (Dimension_System_Root); If a subtype carries dimension
4893 information, obtain the source parent type that carries the

4898 * g-socket.adb, g-socket.ads (GNAT.Sockets.To_Ada): New routine.
4900 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4902 * exp_attr.adb (Expand_N_Attribute_Reference, case 'Constrained):
4903 If the prefix is a reference to an object, rewrite it as an
4904 explicit dereference, as required by 3.7.2 (2) and as is done
4905 with most other attributes whose prefix is an access value.
4907 2017-09-07 Bob Duff <duff@adacore.com>
4909 * par-ch13.adb: Set the Inside_Depends flag if we are inside a
4910 Refined_Depends aspect.

4916 2017-09-07 Hristian Kirtchev <kirtchev@adacore.com>
4918 * exp_ch7.adb (Insert_Actions_In_Scope_Around):
4919 Account for the case where the are no lists to insert, but the
4920 secondary stack still requires management.

4952 in CodePeer mode, to support more legacy code automatically.
4954 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4956 * exp_disp.adb (Replace_Formals): If thr formal is classwide,
4957 and thus not a controlling argument, preserve its type after
4958 rewriting because it may appear in an nested call with a classwide

4969 clause for a unit U appears in a context that includes a regular
4970 with_clause on U, rewrite the redundant private clause into a null
4971 statement, rather than removing it altogether from the context,
4972 so that ASIS tools can reconstruct the original source.

4976 * sem_ch13.adb (Check_Aspect_At_Freeze_Point): The expression

5021 attribute. Defined for record types and subtypes.
5022 * exp_ch3.ads (Init_Secondary_Tags): Adding new formal

5027 generated in the IP routines by means of keeping separate
5028 the initialization of the object components from the
5029 initialization of its dispatch tables. (Init_Secondary_Tags):
5030 Adding new formal (Init_Tags_List) and adjusting calls to
5031 Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;
5032 adjusting also calls to Ada.Tags.Register_Interface_Offset
5033 because the type of one of its formals has been changed.
5034 * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
5035 modified. Instead of receiving a pointer to an object this
5036 routine receives now a primary tag.
5037 (Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
5038 additional formal: the tag of the primary dispatch table.
5039 * exp_disp.ads (Elab_Flag_Needed): New subprogram.
5040 * exp_disp.adb (Elab_Flag_Needed): New subprogram.

5072 is now consulted not only for abstract states and variables,
5073 but for all kinds of items.
5074 (Collect_Subprogram_Inputs_Outputs): Do not process formal
5075 generic parameters, because unlike ordinary formal parameters,
5076 generic formals only act as input/ outputs if they are explicitly
5077 mentioned in a Global contract.
5079 2017-09-07 Yannick Moy <moy@adacore.com>
5081 * ghost.adb (Check_Ghost_Context): Do not err on ghost code inside

5094 derived recor type, copy the dikensions if any of each component
5095 of the parent record to the corresponding component declarations
5096 of the derived record. These expressions are used among other
5097 things as default values in aggregates with box associations.

5115 first attempts to interpret as a malformed expression function.
5117 2017-09-07 Gary Dismukes <dismukes@adacore.com>

5142 Make_Build_In_Place_Call_In_Anonymous_Context): Do not use the
5143 secondary stack for all functions that return limited tagged
5144 types -- just do it for dispatching calls. Misc cleanup.
5145 * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
5146 remove qualifications and type conversions. Fix various bugs
5147 where only a single level of qualification or conversion was
5148 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
5150 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
5153 2017-09-07 Ed Schonberg <schonberg@adacore.com>

5156 do not create actual subtypes that may generate further predicate
5158 * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
5159 of body is a predicate function as well.
5160 (Resolve_Aspect_Expressions, Resolve_Name): For a component
5161 association, only the expression needs resolution, not the name.
5162 (Resolve_Aspect_Expressions, case Predicates): Construct and
5163 analyze the predicate function declaration in the scope of the
5164 type, before making the type and its discriminants visible.

5205 2017-09-06 Bob Duff <duff@adacore.com>
5207 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
5208 requested. Previously, the -do switch meant "run Elab_New and
5209 Elab_Old and use the order chosen by Elab_Old, possibly with
5210 debugging printouts comparing the two orders." Now it means
5211 "do not run Elab_New." This is of use if there are bugs that
5212 cause Elab_New to crash.
5213 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various

5230 <Sized_Component_Total_Round_RM_Size>: New local variable to
5231 accumulate the rounded RM_Size of components. Update it for
5232 every component whose RM_Size is statically known. Add missing
5233 guard to check that bit packing is really required before issuing
5234 the error about packing. Swap condition for clarity's sake.

5258 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
5259 entity of a mutable type and the right-hand side is a conditional
5260 expression, resolve the alternatives of the conditional using
5261 the base type of the target entity, because the alternatives
5262 may have distinct subtypes. This is particularly relevant if
5263 the alternatives are aggregates.
5265 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5267 * checks.adb (Apply_Predicate_Check): If the expression is an
5268 aggregate that is the RHS of an assignment, apply the check to
5269 the LHS after the assignment, rather than to the aggregate. This
5270 is more efficient than creating a temporary for the aggregate,
5271 and prevents back-end crashes when the aggregate includes a
5272 dynamic "others' association.

5294 * errout.adb (Error_Msg): Separate the
5295 treatment for warning vs. style messages in inlinings and
5296 instantiations. Prevents blowups on calls to Warn_Insertion for
5297 style messages, which should not be called in that case because
5298 Warning_Msg_Char is not set.

5305 to centeralize the flagging of attributes for the record type
5306 component case, a pragma applied individually to a component, and

5326 that is a proper body corresponding to a stub, we defer the
5327 adjustment of the sloc until after the correct adjustment has
5328 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
5329 the adjustment, because it will be outside the range in (the old,

5436 we include the proper header. Otherwise, we just declare the necessary
5437 things from the capabilities library. This is so we can build on
5438 machines without that library, while still enabling that library.
5439 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
5440 simply return 0 if the library is not present, or not included

5468 suppress the ".all" suffix when displaying a dereference whose
5469 prefix is a use of a value-capturing compiler temp of the sort

5674 Ada.Command_Line, which would damage the bootstrap process now
5675 that Ada.Command_Line contains modern Ada (the raise expression).
5676 * gnatbind.adb: Avoid dependence on
5677 Ada.Command_Line. Depend on System.Response_File instead
5678 of Ada.Command_Line.Response_File. Change one call to

5680 to Ada.Command_Line.Argument_Count to use Arg_Count.
5681 * gcc-interface/Make-lang.in, Makefile.rtl: Take note of the new files.
5683 2017-09-06 Bob Duff <duff@adacore.com>
5685 * frontend.adb (Frontend): Skip -gnatec=gnat.adc

5749 rule in 6.5.1 (7/2): if a renaming is a completion of a subprogram
5750 with No_Return, the renamed entity must be No_Return as well.
5752 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>
5754 * exp_ch5.adb, freeze.adb, exp_ch4.adb, exp_ch6.adb, lib-xref.adb:

5771 * freeze.adb (Freeze_Entity): Do not generate a freeze
5772 node for a generic unit, even if it includes delayed aspect

5815 * exp_ch5.adb (Make_Field_Assign): If the type
5816 of the right-hand side has stored constraint, use its values
5817 (except for those that are renamings of parent discriminants)
5818 to produce additional assignments for the discriminants of the
5819 left-hand side, which are invisible in the righ-hand side and
5820 not retrievable as selected components.
5822 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5824 * sem_util.adb (Needs_One_Formal): The first formal of such a
5825 function must be a controlling formal, so that Obj.F (X, Y)
5826 can have the interpretation F(Obj)(X, Y).
5827 * sem_util.ads: Clarify documentation.
5829 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>

5844 * sem_ch12.adb (Analyze_Subprogram_Instantiation): Propagate
5845 No_Return flag to instance if pragma applies to generic unit. This
5846 must be done explicitly because the pragma does not appear
5847 directly in the generic declaration (unlike the corresponding
5848 aspect specification).

5859 * exp_ch4.adb (Handle_Changed_Representation): For an untagged
5860 derived type with a mixture of renamed and constrained parent
5861 discriminants, the constraint for the target must obtain the
5862 discriminant values from both the operand and from the stored
5863 constraint for it, given that the constrained discriminants are
5864 not visible in the object.
5865 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
5866 side may be derived from that of the left-hand side (as in the
5867 case of an assignment with a change of representation) so the
5868 discriminant to be used in the retrieval of the value of the
5869 component must be the entity in the type of the right-hand side.
5871 2017-09-06 Hristian Kirtchev <kirtchev@adacore.com>

5898 in a set membership is an overloaded enumeration literal, and
5899 the type of the alternative is resolved from a previous one,
5900 replace the entity of the alternative as well as the type,
5901 to prevent inconsistencies between the entity and the type.

6436 (is_stored_discriminant): New predicate.
6437 (copy_and_substitute_in_layout): Consider only
6438 stored discriminants and check that original fields are present
6439 in the old type. Deal with derived types. Adjust call to
6440 create_variant_part_from.
6442 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6444 * exp_ch6.adb (Expand_Call_Helper): When locating the
6445 accessibility entity created for an access parameter, handle
6446 properly a reference to a formal of an enclosing subprogram. if
6447 the reference appears in an inherited class-wide condition, it
6448 is the rewriting of the reference in the ancestor expression,
6449 but the accessibility entity must be that of the current formal.
6451 2017-05-02 Javier Miranda <miranda@adacore.com>
6453 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

6488 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
6489 procedure body for a local (sub)type declaration within a
6490 predicate function. Invariant checks do not apply to these, and
6491 the expansion of the procedure will happen in the wrong scope,
6492 leading to misplaced freeze nodes.
6494 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6496 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
6497 to analyze generated actions. If the main unit is a body,
6498 the required scope is that of the corresponding unit declaration.
6500 2017-05-02 Arnaud Charlet <charlet@adacore.com>
6502 * einfo.adb (Declaration_Node): flip branches of
6503 an IF statement to avoid repeated negations in its condition;
6504 no change in semantics, only to improve readability.

6508 * sem_case.adb: Remove extra spaces in parameter declarations.
6510 2017-05-02 Justin Squirek <squirek@adacore.com>
6512 * usage.adb: Replace space with hyphen ("run time" -> "run-time")

6533 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
6534 Refine predicate for the case where the primitive operation
6535 is a renaming of equality. An overriding operation that is
6536 a user-defined renaming of predefined equality inherits its
6537 slot from the overridden operation. Otherwise it is treated
6538 as a predefined op and occupies the same predefined slot as
6539 equality. A call to it is transformed into a call to its alias,
6540 which is the predefined equality. A dispatching call thus uses
6541 the proper slot if operation is further inherited and called
6542 with class-wide arguments.
6544 2017-05-02 Justin Squirek <squirek@adacore.com>
6546 * errout.adb (Set_Msg_Text): Add a case to switch the message
6547 type when the character '[' is detected signifying a warning

6549 * opt.ads Add a new Warning_Mode value for new switch
6550 * switch-b.adb (Scan_Binder_Switches): Add case for the binder
6551 to handle new warning mode

6555 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6557 * sem_prag.adb (Process_Conversion): Reject an intrinsic operator
6558 declaration that operates on some fixed point type.

6579 * exp_ch3.adb (Build_Initialization_Call): Generate a null
6580 statement if the initialization call is a null procedure, as
6581 can happen with a controlled type with no explicit Initialize
6582 procedure, or an array of such.
6583 * exp_ch7.adb (Process_Object_Declaration): For a type with
6584 controlled components that has a trivial Initialize procedure,
6585 insert declaration for finalization counter after object

6588 finalization block and attendant declarations if component has
6589 a trivial Initialize procedure.

6621 2017-05-02 Gary Dismukes <dismukes@adacore.com>
6623 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
6624 parameter Array_Comp to indicate the case of an array object
6625 with null-excluding components.
6626 * checks.adb (Null_Exclusion_Static_Checks):
6627 Call Compile_Time_Constraint_Error instead of
6628 Apply_Compile_Time_Constraint_Error in the component case. Also
6629 call that when Array_Comp is True, with an appropriate warning for
6630 the array component case. Only create an explicit initialization
6631 by null in the case of an object of a null-excluding access type
6632 (and no longer do that in the component case).
6633 * sem_ch3.adb (Check_Component): Add a Boolean parameter
6634 Array_Comp defaulted to False. Pass Empty for the Comp
6635 actual when calling Null_Exclusion_Static_Checks in the case
6636 where Comp_Decl matches Object_Decl, because we don't have a
6637 component in that case. In the case of an object or component
6638 of an array type, pass True for Array_Comp on the recursive call

6643 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
6644 compute the linux priority from the Ada priority. Call this everywhere
6645 required. In particular, the previous version was not doing this
6646 computation when setting the ceiling priority in various places. It
6647 was just converting to C.int, which results in a ceiling that is off
6650 2017-05-02 Ed Schonberg <schonberg@adacore.com>

6669 * sem_util.ads, sem_util.adb (Discriminated_Size): Predicate moved
6670 here from exp_ch9, to recognize objects whose creation requires
6671 dynamic allocation, so that the proper warning can be emitted
6672 when restriction No_Implicit_Heap_Allocation is in effect.
6673 * sem_ch3.adb (Analyze_Object_Declaration): Use Discriminated_Size
6674 to emit proper warning when an object that requires dynamic

6684 visibility rules for equality operators that apply within an
6685 instantiation apply within an inlined body.

6722 * checks.adb (Apply_Constraint_Check): Do not apply
6723 a discriminant check when the associated type is a constrained

6752 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
6754 2017-05-02 Bob Duff <duff@adacore.com>
6756 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6757 to find primitive ops, instead of using an Identifier that will
6758 later be looked up. This is necessary because these ops are not
6759 necessarily visible at all places where we need to call them.
6760 * exp_util.ads: Minor comment fix.
6762 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6764 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6765 references are fully conformant if they are both expansions
6766 of the discriminant of a protected type, within one of the
6767 protected operations. One occurrence may be expanded into a
6768 constant declaration while the other is an input parameter to
6769 the corresponding generated subprogram.

6814 * gcc-interface/decl.c (components_to_record): Add more comments.
6815 Put back pending fields onto the regular list if the misalignment
6816 happens to cancel itself.
6818 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6820 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
6821 controlling actual in a prefixed call, preserve the original node
6822 information if the prefix itself has been rewritten, for ASIS use.

6826 * exp_ch6.adb (Insert_Post_Call_Actions):
6827 Code clean up. Insert the post-call actions after an enclosing

6872 * sem_util.ads, sem_util.adb (Might_Raise): New function
6873 that replaces Is_Exception_Safe, but has the opposite
6874 sense. Is_Exception_Safe was missing various cases -- calls inside
6875 a pragma Debug, calls inside an 'if' or assignment statement,
6876 etc. Might_Raise now walks the entire subtree looking for things
6878 * exp_ch9.adb (Is_Exception_Safe): Remove.
6879 (Build_Protected_Subprogram_Body): Replace call to
6880 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use

6926 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
6927 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
6928 code that might violate the more stringent checking for 'Access
6929 introduced in Ada 2005.
6931 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6933 * a-cforse.adb: minor style fix in comment.
6935 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6937 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
6938 initialize Block_Decls variable.
6939 (Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
6940 (Build_Dispatching_Requeue): Add pragma Warnings on Op variable.
6941 * exp_disp.adb (Expand_Interface_Actuals): Initialize
6942 Formal_DDT and Actual_DDT variables.
6943 (Expand_Interface_Thunk): Initialize Iface_Formal.
6944 (Make_DT): Initialize Size_Comp.

6949 * exp_prag.adb (Expand_Pragma_Contract_Cases): Initialize Msg_Str.
6951 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6953 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
6954 node between access types, freeze the designated type as well,
6955 so that dispatch table pointers are created in the proper scope,
6956 and not in the constructed body of the expression function.
6958 2017-04-28 Bob Duff <duff@adacore.com>
6960 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6961 value makes large compilations faster, but small compilations slower.
6963 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6965 * sem_util.adb: minor typos in Is_Child_Or_Sibling.
6967 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6969 * erroutc.adb (Compilation_Errors): Do not consider info messages
6970 as suitable warnings when warnings must be treated as errors.
6971 * sem_ch7.adb (Analyze_Package_Specification): Do not consider
6972 internally-generated packages when outputting completion
6974 * errout.adb (Output_Messages): Do not consider info messages as
6975 suitable warnings when warnings must be treated as errors.
6976 * errutil.adb (Finalize): Do not consider info messages as
6977 suitable warnings when warnings must be treated as errors.

6981 * warnsw.ads: Minor fix for incorrect wording in comment.
6983 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6985 * sem_res.adb (In_Instance_Code): New predicate in
6986 Valid_Conversion, to determine whether a type conversion appears
6987 as (or within) an actual for a formal object. Type conversions
6988 in instances are not rechecked in Valid_Conversion because
6989 visibility changes between generic location andi instance may
6990 lead to spurious errors, but conversions within an actual must be
6991 fully checked, and they are not fully resolved when pre-analyzing
6994 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6996 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
6997 New_Copy_Tree instead of Relocate_Node as any subsequent copies
6998 of the relocated node will have mangled Parent pointers.
6999 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
7000 tables used in conjunction with entity and itype replication.
7001 (Visit_Entity): Rewrite the restriction on which entities

7036 (Restore_Warnings): Likewise.
7037 (Save_Warnings): Likewise.
7038 (Set_Dot_Warning_Switch): Handle 'q' and 'Q' letters.
7039 * gcc-interface/decl.c (gnat_to_gnu_entity): Adjust call to
7040 components_to_record.
7041 (gnu_field_to_gnat): New function.
7042 (warn_on_field_placement): Likewise.
7043 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
7044 parameters. Rename local variables and adjust recursive call.
7045 Rework final scan of the field list and implement warnings on the
7046 problematic placement of specific sorts of fields.
7048 2017-04-27 Bob Duff <duff@adacore.com>

7055 * sem_intr.adb, sem_res.adb, sem_util.adb, sem_warn.adb, sprint.adb:
7056 For efficiency, cache results of Is_Internal_File_Name and
7057 Is_Predefined_File_Name in the Units table. This avoids a lot
7058 of repeated text processing.
7060 2017-04-27 Emmanuel Briot <briot@adacore.com>
7062 * g-comlin.adb (Sort_Sections): remove useless test.
7064 2017-04-27 Claire Dross <dross@adacore.com>
7066 * a-cfhase.adb, a-cfhase.ads (=): Generic parameter removed to
7067 allow the use of regular equality over elements in contracts.
7068 (Formal_Model): Ghost package containing model functions that are
7069 used in subprogram contracts.
7070 (Current_To_Last): Removed, model functions should be used instead.
7071 (First_To_Previous): Removed, model functions should be used instead.
7072 (Strict_Equal): Removed, model functions should be used instead.
7073 (No_Overlap): Removed, model functions should be used instead.
7074 (Equivalent_Keys): Functions over cursors are removed. They were
7075 awkward with explicit container parameters.
7076 * a-cforse.adb, a-cforse.ads (=): Generic parameter removed to
7077 allow the use of regular equality over elements in contracts.
7078 (Formal_Model): Ghost package containing model functions that

7087 * gnat1drv.adb: Code cleanup.
7089 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7091 * exp_util.adb (Replace_Entity): The prefix of a 'Result
7092 attribute reference in a post- condition is the subprogram to
7093 which the condition applies. If the condition is inherited
7094 by a type extension, the prefix becomes a reference to the
7095 inherited operation, but there is no need to create a wrapper
7096 for this operation, because 'Result is expanded independently
7097 when elaborating the postconditions.
7099 2017-04-27 Bob Duff <duff@adacore.com>
7101 * sinput.adb: Minor code cleanup.
7102 * namet.adb (Append): Create faster versions of
7103 Append(String) and Append(Name_Id) by using slice assignment

7108 * sem_util.ads, sem_util.adb (In_Parameter_Specification):
7109 Remove unused function.
7110 * alloc.ads (Nodes_Initial): Use a much larger value, because
7111 the compiler was spending a lot of time copying the nodes table
7112 when it grows. This number was chosen in 1996, so is rather out
7113 of date with current memory sizes. Anyway, it's virtual memory.
7114 Get rid of Orig_Nodes_...; use Node_... instead.
7115 * atree.adb (Lock): Do not release the Nodes tables; it's a
7117 Orig_Nodes_ ==> Nodes_
7118 * nlists.adb: Orig_Nodes_ ==> Nodes_
7119 * g-table.adb: Remove unused "with" clause.
7120 * g-table.ads, table.ads: Remove Big_Table_Type, which should
7121 not be used by clients.
7122 * g-dyntab.adb (Last_Allocated): New function
7123 to encapsulate T.P.Last_Allocated, which I'm thinking of changing.

7146 for qualified expressions, type conversions, and unchecked
7148 * sem_util.adb (Compile_Time_Constraint_Error): Merge the
7149 processing for Ada 83 and instances.
7150 (Object_Access_Level): Merge the processing for indexed components
7151 and selected components.
7152 * uname.adb (Add_Node_Name): Merge the processing for stubs.
7154 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>

7162 * exp_disp.adb (Build_Class_Wide_Check): New subsidiary
7163 of Expand_Dispatching_Call. If the denoted subprogram has a
7164 class-wide precondition, this is the only precondition that
7165 applies to the call, rather that the class-wide preconditions
7166 that may apply to the body that is executed. (This is specified
7169 2017-04-27 Yannick Moy <moy@adacore.com>
7171 * gnat1drv.adb (Adjust_Global_Switches): Issue
7172 a warning in GNATprove mode if the runtime library does not
7173 support IEEE-754 floats.
7175 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7177 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
7178 is itself inherited it does not carry any contract information,
7179 so examine its parent operation which is its Alias.
7181 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7183 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
7184 prefix can be an object reference in which case Obj'Image (X)
7185 can only be interpreted as an indexing of the parameterless
7186 version of the attribute.
7187 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
7188 an indexing or a slice operation if the attribute does not require
7189 parameters. In Ada2012 'Image also belongs in this category,
7190 and A'Image (lo .. hi) is legal and must be parsed as a slice.
7192 2017-04-27 Yannick Moy <moy@adacore.com>
7194 * exp_ch4.adb: Minor reformatting.
7195 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,
7196 disable the CodePeer and C generation modes. Similar to the
7197 opposite actions done in CodePeer mode.

7327 (Move, Release_Threshold).
7328 * g-table.ads, g-table.adb: This is now just a thin wrapper
7329 around g-dyntab.ads/g-dyntab.adb. Add functionality supported

7331 * table.ads, table.adb: This is now just a thin wrapper around
7332 * g-table.ads/g-table.adb.
7333 * namet.h, scos.h, uintp.h: These files are reaching into the

7535 contains calls to other primitives.
7536 (Build_Class_Wide_Clone_Call); Build a call to the common
7537 class-wide clone of a subprogram with classwide conditions. The
7538 body of the subprogram becomes a wrapper for a call to the

7852 to manage the secondary stack when an enclosing scope already
7853 performs this functionality (aka relaxed management). Switch
7854 -gnatd.s may be used to force strict management in which case
7855 the block will manage the secondary stack unconditionally. Add

7862 limited views of return types in function calls. If the function
7863 that returns a limited view appears in the current unit,
7864 we do not replace its type by the non-limited view because
7865 this transformation is performed int the back-end. However,
7866 the type of the call itself must be the non-limited view, to
7867 prevent spurious resolution errors.

7874 (Class_Wide_Clone): New attribute of subprogram. Designates
7875 subprogram created for primitive operations with class-wide
7876 pre/postconditions that contain calls to other primitives. The
7877 clone holds the body of the original primitive, but the
7878 pre/postonditions do not apply to it. The original body is
7879 rewritten as a wrapper for a call to the clone.
7880 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7881 the flag is set, no code for the corresponding pre/postconditions
7882 is inserted into its body.

8430 * exp_attr.adb (Expand_Attribute_Reference, case 'Read):
8431 If the type is an unchecked_union, replace the attribute with
8432 a Raise_Program_Error (rather than inserting such before the

8434 processing a component of a larger record, and we need to prevent
8435 further expansion for the unchecked union.
8436 (Expand_Attribute_Reference, case 'Write): If the type is
8437 an unchecked_union, check whether enclosing scope is a Write
8438 subprogram. Replace attribute with a Raise_Program_Error if the
8439 discriminants of the unchecked_union type have not default values
8440 because such a use is erroneous..

8527 When resolving against any fixed type, set the type of the
8528 operand as universal real when the operand is a multiplication
8529 or a division where both operands are of any fixed type.
8530 (Unique_Fixed_Point_Type): Add local variable ErrN. Improve the
8531 placement of an error message by pointing to the operand of a
8532 type conversion rather than the conversion itself.

8606 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8608 * sem_dim.adb (Dimensions_Of_Operand): minot cleanups: a) If

8660 to return if an interface type is encountered and add
8661 condition to convert the formal parameter to its class-wide
8662 counterpart if Work_Typ is abstract.

8684 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
8685 (10-15): if derived type T with progenitors is abstract,
8686 and primitive P of this type inherits non-trivial classwide
8687 preconditions from both a parent operation and from an interface
8688 operation, then the inherited operation is abstract if the parent
8689 operation is not null.
8690 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
8691 with Covered_Interface_Op to yield the actual interface operation
8692 that is implemented by a given inherited operation.

8730 * a-numeri.ads: Change the encoding of Greek letter Pi from
8731 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
8732 to indicate the encoding. We considered using a byte order mark
8733 (BOM), but that causes various trouble (misc software eats the
8734 BOM, if you have a patch with a BOM, then it's not at the start
8735 of the patch, so it's not a BOM, the BOM affects with-ing files,

8782 subprogram need not be dispatching if it appears in a precondition
8783 for an abstract or null subprogram.

8932 * fname.adb (Has_Internal_Extension): Add pragma Inline.
8933 Use direct 4-character slice comparisons.
8935 pragma Inline. (Has_Suffix): Delete.
8936 (Is_Internal_File_Name):
8937 Test Is_Predefined_File_Name first.
8938 (Is_Predefined_File_Name):
8939 Use direct slice comparisons as much as possible and limit all
8940 comparisons to at most 8 characters.
8942 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8944 * checks.adb (Insert_Valid_Check): Code cleanup.
8945 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8946 (Expand_Actuals): Generate proper copy-back for a validation
8947 variable when it acts as the argument of a type conversion.
8948 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8949 predicate to operate on type qualifications.
8951 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8953 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8956 2017-04-25 Bob Duff <duff@adacore.com>
8958 * sem_prag.adb (No_Return): Give an error if the pragma applies
8959 to a body. Specialize the error for the specless body case,
8960 as is done for (e.g.) pragma Convention.
8961 * debug.adb: Add switch -gnatd.J to disable the above legality
8962 checks. This is mainly for use in our test suite, to avoid
8963 rewriting a lot of illegal (but working) code. It might also
8964 be useful to customers. Under this switch, if a pragma No_Return
8965 applies to a body, and the procedure raises an exception (as it
8966 should), the pragma has no effect. If the procedure does return,
8967 execution is erroneous.
8969 2017-04-25 Bob Duff <duff@adacore.com>
8971 * exp_ch6.adb (Expand_Actuals): This is the
8972 root of the problem. It took N as an 'in out' parameter, and in
8973 some cases, rewrote N, but then set N to Original_Node(N). So
8974 the node returned in N had no Parent. The caller continued
8975 processing of this orphaned node. In some cases that caused a
8976 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8977 and trips over the Empty Parent). The solution is to make N an
8978 'in' parameter. Instead of rewriting it, return the list of
8979 post-call actions, so the caller can do the rewriting later,
8980 after N has been fully processed.
8981 (Expand_Call_Helper): Move most of Expand_Call here. It has
8982 too many premature 'return' statements, and we want to do the
8983 rewriting on return.
8984 (Insert_Post_Call_Actions): New procedure to insert the post-call
8985 actions in the appropriate place. In the problematic case,
8986 that involves rewriting N as an Expression_With_Actions.
8987 (Expand_Call): Call the new procedures Expand_Call_Helper and
8988 Insert_Post_Call_Actions.
8990 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8992 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
8993 properly type derived from generic formal types, to handle
8994 properly modified version of ACATS 4.1B B611017.
8996 2017-04-25 Javier Miranda <miranda@adacore.com>
8998 * exp_unst.adb (Subp_Index): Adding missing
8999 support for renamings and functions that return a constrained
9000 array type (i.e. functions for which the frontend built a
9001 procedure with an extra out parameter).
9003 2017-04-25 Pascal Obry <obry@adacore.com>
9005 * s-string.adb: Minor code clean-up.
9007 2017-04-25 Bob Duff <duff@adacore.com>

9014 2017-04-25 Bob Duff <duff@adacore.com>
9016 * prep.adb (Preprocess): Remove incorrect
9017 Assert. Current character can be ASCII.CR.
9019 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9021 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
9022 convention Stdcall, which has a number of exceptions. Convention
9023 is legal on a component declaration whose type is an anonymous
9024 access to subprogram.
9026 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9028 * sem_ch4.adb: sem_ch4.adb Various reformattings.
9029 (Try_One_Prefix_Interpretation): Use the base type when dealing
9030 with a subtype created for purposes of constraining a private
9031 type with discriminants.
9033 2017-04-25 Javier Miranda <miranda@adacore.com>

9037 dispatching primitives (Restore_Warnings): Restore warning on
9038 late dispatching primitives (Save_Warnings): Save warning on late
9039 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
9040 to enable/disable this warning.
9041 (WA_Warnings): Set warning on late dispatching primitives.
9042 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
9043 that its parent type has a private extension.
9044 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
9046 * usage.adb: Document -gnatw.j and -gnatw.J.
9048 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9050 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
9053 2017-04-25 Bob Duff <duff@adacore.com>
9055 * binde.adb (Validate): Do not pass dynamic strings
9056 to pragma Assert, because older compilers do not support that.
9058 2017-04-25 Bob Duff <duff@adacore.com>
9060 * s-fileio.adb (Close): When a temp file is
9061 closed, delete it and clean up its Temp_File_Record immediately,
9062 rather than waiting until later.
9063 (Temp_File_Record): Add File
9064 component, so Close can know which Temp_File_Record corresponds
9065 to the file being closed.
9066 (Delete): Don't delete temp files,
9067 because they are deleted by Close.
9068 (Open): Set the File component
9069 of Temp_File_Record. This requires moving the creation of the
9070 Temp_File_Record to the end, after the AFCB has been created.
9072 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9074 * checks.adb (Insert_Valid_Check): Do not generate
9075 a validity check when inside a generic.
9077 2017-04-25 Yannick Moy <moy@adacore.com>
9079 * sem_res.adb (Resolve_Type_Conversion): Fix bad logic.
9081 2017-04-25 Arnaud Charlet <charlet@adacore.com>

9089 concerning inheritance of class-wide preconditions do not apply
9092 2017-04-25 Bob Duff <duff@adacore.com>
9094 * s-ficobl.ads: Minor comment fix.
9096 2017-04-25 Yannick Moy <moy@adacore.com>
9098 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
9099 conversions from float to integer in GNATprove mode.
9100 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
9101 to call Apply_Type_Conversion_Checks, so that range checks
9102 are properly positioned when needed on conversions, including
9103 when converting from float to integer. (Determine_Range): In
9104 GNATprove mode, take into account the possibility of conversion
9105 from float to integer.
9106 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
9107 check on conversions from fixed-point to integer, not anymore
9108 on conversions from floating-point to integer, when in GNATprove
9111 2017-04-25 Yannick Moy <moy@adacore.com>
9113 * checks.adb (Determine_Range_R): Special case type conversions
9114 from integer to float in order to get bounds in that case too.
9115 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
9116 mode, for computations involved in interval checking.

9129 (Set_Validated_Object): New routine along with pragma Inline.
9130 * exp_attr.adb (Make_Range_Test): Add processing for validation
9131 variables to avoid extra reads and copies of the prefix.
9132 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
9133 variables in order to reflect any changes done in the variable
9134 back into the original object.
9135 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
9136 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

9142 generate Finalize_Address routines for CodePeer.
9144 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9146 * sem_prag.adb (Inherits_Class_Wide_Pre): subsidiary of
9147 Analyze_Pre_Post_Condition, to implement the legality checks
9148 mandated by AI12-0131: Pre'Class shall not be specified for an
9149 overriding primitive subprogram of a tagged type T unless the
9150 Pre'Class aspect is specified for the corresponding primitive
9151 subprogram of some ancestor of T.
9153 2017-04-25 Bob Duff <duff@adacore.com>
9155 * sem_ch8.adb (Use_One_Type): If a use_type_clause
9156 is redundant, set its Used_Operations to empty. This is only
9157 necessary for use clauses that appear in the parent of a generic
9158 child unit, because those use clauses get reanalyzed when we
9159 instantiate the generic, and we don't want the Used_Operations
9160 carried over from the original context (where it was probably
9163 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9165 * exp_ch6.adb: Minor reformatting.
9167 2017-04-25 Bob Duff <duff@adacore.com>
9169 * sem_prag.adb (Process_Restrictions_Or_Restriction_Warnings):

9172 (Current_Sem_Unit) to find the correct casing.
9173 * par.adb (Par): Null out Current_Source_File, to ensure that
9174 the above bugs won't rear their ugly heads again.
9176 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9178 * sem_ch8.adb (Find_Type): For an attribute reference
9179 'Class, if prefix type is synchronized and previous errors
9180 have suppressed the creation of the corresponding record type,
9181 create a spurious class-wide for the synchonized type itself,
9182 to catch other misuses of the attribute
9184 2017-04-25 Steve Baird <baird@adacore.com>
9186 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode

9188 tag of a tagged result.
9189 * exp_intr.adb (Expand_Dispatching_Constructor_Call):
9190 if CodePeer_Mode is True, then don't generate the
9191 tag checks for the result of call to an instance of
9192 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
9193 descendant of" check and the accessibility check).
9195 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9197 * sem_ch13.adb: Code cleanups.
9198 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

9203 * exp_ch4.adb (Library_Level_Target): New function.
9204 (Expand_Concatenate): When optimization is enabled, also expand
9205 the operation out-of-line if the concatenation is present within
9206 the expression of the declaration of a library-level object and
9207 not only if it is the expression of the declaration.
9209 2017-04-25 Bob Duff <duff@adacore.com>
9211 * freeze.adb (Freeze_Object_Declaration): Do
9212 not Remove_Side_Effects if there is a pragma Linker_Section,
9213 because in that case we want static initialization in the
9214 appropriate section.
9216 2017-04-25 Gary Dismukes <dismukes@adacore.com>
9218 * exp_dbug.adb: Minor rewording and reformatting.
9220 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9222 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
9223 handle the proposed changes to rules concerning potentially
9224 unevaluated expressions, to include selected components that
9225 do not depend on discriminants, and indexed components with
9227 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
9228 predicate in quantified expression, and fix bugs in the handling
9229 of case expressions and membership test.
9230 (Analyze_Attribute_Old_Result): use new predicate.
9231 (Analyze_Attribute, case Loop_Entry): ditto.
9233 2017-04-25 Bob Duff <duff@adacore.com>
9235 * s-secsta.adb (SS_Info): Add a comment
9236 explaining why we don't need to walk all the chunks in order to
9237 compute the total size.
9239 2017-04-25 Bob Duff <duff@adacore.com>
9241 * namet.ads, namet.adb (Global_Name_Buffer): Increase the length
9242 of the global name buffer to 4*Max_Line_Length.

9247 renaming entity for debug information, mark the entity as needing debug
9248 info if it comes from sources.
9250 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9252 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
9253 restriction converning the use of 'Address where the prefix is
9254 of a controlled type.
9256 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>

9271 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
9272 internal calls that appear in preconditions of protected
9273 operations, in default values for same, and in contract guards
9274 for contract cases in SPARK.

9282 * a-numaux-darwin.ads
9284 * a-numaux-libc-x86.ads (Double): Define to Long_Long_Float.
9285 * a-numaux-x86.ads: Fix package description.
9286 * a-numaux-x86.adb (Is_Nan): Minor tweak.
9287 (Reduce): Adjust and complete description. Call Is_Nan instead of
9288 testing manually. Use an integer temporary to hold rounded value.
9289 * a-numaux-darwin.adb (Reduce): Likewise.

9301 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
9302 the identity of callable entities therein, because they have been
9303 properly resolved, and prefixed calls may have been rewritten
9306 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
9308 * exp_ch3.adb (Build_Init_Statements): Convert
9309 the expression of the pragma/aspect Secondary_Stack_Size to
9310 internal type System.Parameters.Size_Type before assigning
9311 it to the Secondary_Stack_Size component of the task type's
9312 corresponding record.

9322 * s-osinte-freebsd.ads: Minor comment tweaks
9324 2017-04-25 Javier Miranda <miranda@adacore.com>
9326 * urealp.adb (UR_Write): Reverse previous patch
9327 adding documentation on why we generate multiplications instead
9328 of divisions (needed to avoid expressions whose computation with
9329 large numbers may cause division by 0).
9331 2017-04-25 Bob Duff <duff@adacore.com>
9333 * erroutc.adb (Set_Specific_Warning_Off,
9334 Set_Warnings_Mode_Off): Use the correct source file for
9335 Stop. Was using Current_Source_File, which is only valid during
9336 parsing. Current_Source_File will have a leftover value from
9337 whatever file happened to be parsed last, because of a with_clause
9340 2017-04-25 Bob Duff <duff@adacore.com>
9342 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
9343 to In_Predefined_Unit, but including GNAT units.
9344 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
9345 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
9346 because Should_Ignore_Pragma was not working reliably outside
9347 the parser, because Current_Source_File is not valid.
9348 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
9349 * par-prag.adb: Call Should_Ignore_Pragma_Par.

9418 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
9419 of prefix whose type is a current instance of a synchronized
9420 type. If the prefix is an object this is an external call (or
9421 requeue) that can only access public operations of the object. The
9422 previous predicate was too restrictive, and did not allow public
9423 protected operations, only task entries.
9425 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9427 * sem_ch5.adb, fname.adb: Minor reformatting.

9437 master for an access type subject to pragma No_Heap_Finalization.
9438 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
9439 allocated or deallocated does not finalization actions if the
9440 associated access type is subject to pragma No_Heap_Finalization.
9441 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
9442 * par-prag.adb Pragma No_Heap_Finalization does not need special
9443 processing from the parser.
9444 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
9445 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
9446 * sem_prag.adb Add an entry in table Sig_Flags for pragma
9447 No_Heap_Finalization.
9448 (Analyze_Pragma): Add processing for

9451 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
9452 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
9453 and corresponding pragma id.
9455 2017-04-25 Bob Duff <duff@adacore.com>
9457 * freeze.adb (Freeze_Record_Type): Use the
9458 underlying type of the component type to determine whether it's
9459 elementary. For representation clause purposes, a private type
9460 should behave the same as its full type.
9461 * fname.ads, fname.adb (Is_Predefined_File_Name):
9462 Make sure things like "system.ali" are recognized as predefined.
9464 2017-04-25 Javier Miranda <miranda@adacore.com>

9476 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
9477 Is_Internal_Unit_Name): New functions for operating on unit
9478 names, as opposed to file names. There's some duplicated code
9479 with fname.adb, which is unfortunate, but it seems like we don't
9480 want to add dependencies here.
9481 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
9482 to Is_Predefined_Unit_Name; the former was wrong, because Uname
9483 is not a file name at all.
9484 * fname.ads, fname.adb: Document the fact that
9485 Is_Predefined_File_Name and Is_Internal_File_Name can be called
9486 for ALI files, and fix the code so it works properly for ALI
9487 files. E.g. these should return True for "system.ali".
9489 2017-04-25 Justin Squirek <squirek@adacore.com>
9491 * exp_util.adb (Add_Invariant): Removed,
9492 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
9493 and Add_Own_Invariant. (Add_Invariant_Check): Used
9494 for adding runtime checks from any kind of invariant.
9495 (Add_Inherited_Invariant): Generates invariant checks for

9501 and integrated code from Add_Parent_Invariants and
9502 Add_Interface_Invariants.
9503 (Process_Type): Removed, the
9504 relavant code was inlined into both Add_Own_Invariant and
9505 Add_Inherited_Invariant.

9528 and Build_Invariant_Procedure_Declaration from exp_ch7
9529 and break-out Is_Untagged_Private_Derivation from
9530 Build_Invariant_Procedure_Body.
9531 (Replace_Type_References):
9532 Append an extra parameter to allow for dispatching replacements
9533 and add the corrasponding logic.
9534 (Type_Invariant): Remove
9535 Replace_Typ_Refs and replace its references with calls to
9536 Replace_Type_References.
9537 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.

9542 that returns True when appropriate.
9543 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
9544 when compiling predefined files.
9545 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
9546 "gnat.adc" should not be considered a predefined file name.
9547 That required (or at least encouraged) a lot of cleanup of global
9548 variable usage. We shouldn't be communicating information via
9549 the global name buffer.
9550 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
9551 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

9611 the first pass over an assignment statement with target names,
9612 to prevent the generation of subtypes (such as discriminated

9630 For_Freeze. Add local variable Build_Body. Inherited DIC pragmas
9631 are now only processed when freezing occurs. Build a body only

9650 * sem_prag.adb (Analyze_Pragma): Guard against a case where a
9651 DIC pragma is placed at the top of a declarative region.
9653 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

9661 the error message when the attribute reference is an actual in
9662 a call to a subprogram inherited from a generic formal type with
9663 unknown discriminants, which makes the subprogram and its formal
9664 parameters intrinsic (see RM 6.3.1 (8) and (13)).
9666 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9668 * sem_aggr.adb, inline.adb, einfo.adb, einfo.ads, scng.adb,

10440 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
10441 an object declaration for an array type with a modular index type
10442 with the size of Long_Long_Integer. Special processing is needed
10443 in this case to compute reliably the size of the object, and
10444 eventually to raise Storage_Error, when wrap-around arithmetic
10445 might compute a meangingless size for the object.
10447 2017-01-23 Justin Squirek <squirek@adacore.com>

10455 it is deciding whether to turn the call into an indexed
10456 component, avoid doing so if the call is to an instance of
10457 Unchecked_Conversion. Otherwise, the compiler turns it into an
10458 indexed component, and resolution of that turns it back into a
10459 function call, and so on, resulting in infinite recursion.
10460 * sem_util.adb (Needs_One_Actual): If the first formal has a
10461 default, then return False.

10563 returns a limited view of a type and at the point of the call the
10564 function is not declared in the extended main unit then replace
10565 it with the non-limited view, which must be available. If the
10566 called function is in the extended main unit then no action is
10567 needed since the back-end handles this case.

10915 * sem_ch6.adb (Analyze_Procedure_Call): In SPARK_Mode and within
10916 an Inlined_body, recognize a call that uses object notation
10917 and has not been rewritten as a regular call because regular
10918 expansion has not taken place.
10920 2017-01-19 Bob Duff <duff@adacore.com>
10922 * checks.adb (Apply_Type_Conversion_Checks): Disable small optimization
10923 in case of generic formal discrete types, because it causes crashes in
10924 the compiler when built with assertions on.
10926 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
10928 * lib-xref-spark_specific.adb, sem_util.adb, sem_util.ads,
10929 sem_ch4.adb, sem_ch8.adb, lib-xref.ads: Minor reformatting.
10931 2017-01-19 Bob Duff <duff@adacore.com>
10933 * bcheck.adb (Check_Consistent_Dynamic_Elaboration_Checking):
10934 Increment Warnings_Detected. It was decrementing, which is
10935 wrong since we just issued a warning message.
10936 * binderr.ads (Errors_Detected, Warnings_Detected): Declare
10937 these variables to be of subtype Nat instead of Int, because
10938 they should never be negative.
10940 2017-01-19 Javier Miranda <miranda@adacore.com>
10942 * contracts.adb (Build_Postconditions_Procedure): Replace
10943 Generate_C_Code by Modify_Tree_For_C.
10944 * exp_aggr.adb (Build_Record_Aggr_Code, Expand_Array_Aggregate):
10945 Replace Generate_C_Code by Modify_Tree_For_C.

10948 * exp_ch11.adb (Expand_N_Exception_Declaration): Replace
10949 Generate_C_Code by Modify_Tree_For_C.

10956 * sem_res.adb (Resolve_Type_Conversion): Replace Generate_C_Code
10957 by Modify_Tree_For_C.
10958 * sinfo.ads (Modify_Tree_For_C): Adding documentation.
10960 2017-01-19 Javier Miranda <miranda@adacore.com>
10962 * sem_util.ads, sem_util.adb (Expression_Of_Expression_Function): New
10964 (Is_Inlinable_Expression_Function): New subprogram.
10965 * exp_ch6.ads, exp_ch6.adb (Expression_Of_Expression_Function): Moved
10967 (Is_Inlinable_Expression_Function): Moved to Sem_Util.
10969 2017-01-19 Ed Schonberg <schonberg@adacore.com>
10971 * sem_ch4.adb (Diagnose_Call): Improve error message when a
10972 selected component has a prefix that might be interpreted
10973 as a parameterless function call, but none of the candidate
10974 interpretations is parameterless, and there is a hidden homonym
10975 of the prefix that is a package.
10976 * sem_ch8.adb (Find_Selected_Component): If the prefix might be
10977 interpreted as a parameterless function call and its analysis
10978 fails, do not call Analyze_Selected_Component.
10980 2017-01-19 Steve Baird <baird@adacore.com>
10982 * sem_util.ads: Add new Use_Full_View Boolean parameter to
10984 * sem_util.adb (Get_Index_Bounds): replace calls to Scalar_Range with
10985 calls to a newly-defined Scalar_Range_Of_Right_View function.
10987 2017-01-19 Arnaud Charlet <charlet@adacore.com>
10989 * gnat1drv.adb: minor fix of unbalanced parens in comment
10990 * lib-xref.ads (Traverse_Compilation_Unit): declaration moved
10991 to visible part of the package to allow re-use in GNATprove.
10992 * lib-xref-spark_specific.adb (Traverse_Stub): routine refactored
10993 from repeated code of Traverse_Compilation_Unit.
10994 (Traverse_Declaration_Or_Statement): fixed detection of
10995 generic subprograms and packages; also, iteration over case
10996 statement alternatives rewritten to avoid testing if the first
10997 alternative is present (since it must be present due to Ada
10998 syntax restrictions).
11000 2017-01-19 Hristian Kirtchev <kirtchev@adacore.com>
11002 * exp_ch6.adb (Expand_N_Subprogram_Body): Mark the spec as
11003 returning by reference not just for subprogram body stubs,
11004 but for all subprogram cases.
11005 * sem_util.adb: Code reformatting.
11006 (Requires_Transient_Scope): Update the call to Results_Differ.
11007 (Results_Differ): Update the parameter profile and the associated
11010 2017-01-19 Ed Schonberg <schonberg@adacore.com>
11012 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
11013 identifier nodes that do not come from source, to handle properly
11014 dimensionality check within an inlined body which inclddes both
11015 original operands and rewritten operands. This removes spurious
11016 dimensionality errors in the presence of front-end inlining,
11017 as well as in SPARK mode.
11019 2017-01-16 Jakub Jelinek <jakub@redhat.com>
11022 * gcc-interface/lang.opt (gant, gnatO, gnat): Add Driver flag.
11024 2017-01-13 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE>
11026 * gcc-interface/Makefile.in (SPARC/Solaris): Fix typo.

11055 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11057 * einfo.ads: minor grammar fixes in comment of Normalized_Position_Max.
11058 * scil_ll.adb: Minor style fix in comment.
11059 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
11060 even if entity is already set, because the node may be renalyzed
11061 after inlining transformations.
11063 2017-01-13 Javier Miranda <miranda@adacore.com>
11065 * sem_res.adb (Resolve_Call): Do not establish a transient scope
11066 for a call to inlinable expression function (since the call will
11067 be replaced by its returned object).
11068 * exp_ch6.ads (Is_Inlinable_Expression_Function): New subprogram.
11069 * exp_ch6.adb (Expression_Of_Expression_Function): New subprogram.
11070 (Expand_Call): For inlinable expression function call replace the
11071 call by its returned object.
11072 (Is_Inlinable_Expression_Function): New subprogram.
11074 2017-01-13 Gary Dismukes <dismukes@adacore.com>
11076 * checks.adb: Minor typo fix and reformatting.
11078 2017-01-13 Javier Miranda <miranda@adacore.com>
11080 * contracts.adb (Contract_Only_Subprograms): Remove formal.
11081 (Copy_Original_Specification): Removed.
11082 (Skip_Contract_Only_Subprogram): Move here checks previously
11083 located in the caller of this routine (to leave the code more clean).
11084 (Build_Contract_Only_Subprogram): Code cleanup.
11085 * scil_ll.ads, scil_ll.adb (Get_Contract_Only_Body_Name): Removed.
11086 (Get_Contract_Only_Missing_Body_Name): Removed.
11088 2017-01-13 Javier Miranda <miranda@adacore.com>
11090 * sem_ch6.adb (Cloned_Expression): New subprogram.
11091 (Freeze_Expr_Types): Complete previous patch since the expression
11092 of an expression-function may have iterators and loops with
11093 defining identifiers which, as part of the preanalysis of the
11094 expression, may be left decorated with itypes that will not be
11095 available in the tree passed to the backend.
11097 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11099 * checks.adb (Apply_Type_Conversion_Checks): Optimize a type
11100 conversion to Integer of an expression that is an attribute
11101 reference 'Pos on an enumeration type.
11103 2017-01-13 Bob Duff <duff@adacore.com>
11105 * atree.ads: Minor comment fix.
11107 2017-01-13 Justin Squirek <squirek@adacore.com>
11109 * sem_ch6.adb (Check_Aggregate_Accessibility): Ignore function
11110 calls in accessibility check on return statement.
11112 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11114 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
11115 Ensure that the input body is a subprogram body before trying to
11116 determine whether it denoted an expression function. Note that
11117 subprogram body stubs cannot denote expression functions.
11119 2017-01-13 Gary Dismukes <dismukes@adacore.com>
11121 * bindgen.adb, sem_ch6.adb, binde.adb, exp_ch3.adb: Minor reformatting
11124 2017-01-13 Javier Miranda <miranda@adacore.com>
11126 * einfo.ads (Component_Bit_Offset): Fix documentation.
11127 * sem_ch13.adb (Check_Record_Representation_Clause): Skip check
11128 on record holes for components with unknown compile-time offsets.
11130 2017-01-13 Bob Duff <duff@adacore.com>
11132 * ali.ads, ali.adb (Static_Elaboration_Model_Used): Remove unused flag.
11133 * g-locfil.ads: Minor comment fix.
11135 2017-01-13 Bob Duff <duff@adacore.com>
11137 * binde.adb (Elab_New): New elaboration order algorithm
11138 that is expected to cause fewer ABE issues. This is a work in
11139 progress. The new algorithm is currently disabled, and can be
11140 enable by the -dp switch, or by modifying the Do_Old and Do_New
11141 etc. flags and rebuilding. Experimental code is included to
11142 compare the results of the old and new algorithms.
11143 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
11144 can have multiple of these tables, so the old and new algorithms
11146 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
11147 parameter of type array. This avoids the global variable, and
11148 allows bounds checking (which is normally defeated by the tables
11149 packages). It also ensures that the Elab_Order is read-only
11151 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
11152 subprograms that need it, as above.
11153 * debug.adb: Document new -dp switch. Modify doc of old -do
11155 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
11156 and Bindgen. Move writing of closure (-R and -Ra switches)
11157 to Binde; that's more convenient.
11159 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11161 * sem_ch6.adb (Analyze_Expression_Function): If the expression
11162 function is a completion, all entities referenced in the
11163 expression are frozen. As a consequence, a reference to an
11164 uncompleted private type from an enclosing scope is illegal.
11166 2017-01-13 Javier Miranda <miranda@adacore.com>
11168 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
11169 (Analyze_Subprogram_Body_Helper): At the occurrence of an
11170 expression function declaration that is a completion, its
11171 expression causes freezing (AI12-0103).
11173 2017-01-13 Vadim Godunko <godunko@adacore.com>
11175 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and
11176 Reference functions of Ada.Containers.Indefinite_Holders.
11178 2017-01-13 Bob Duff <duff@adacore.com>
11180 * s-os_lib.ads: Minor comment fixes.
11182 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11184 * exp_ch3.adb (Default_Initialize_Object): Do not default
11185 initialize an object when it is of a task type and restriction
11186 No_Tasking is in effect because the initialization is obsolete.
11187 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
11188 restriction No_Tasking is in effect.
11189 (Build_Master_Renaming): Do not rename a master when restriction
11190 No_Tasking is in effect.
11192 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11194 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
11195 the legality of An others clause applies as well to a choice in
11196 an Iterated_component_ association.
11197 (Resolve_Iterated_Component_Association): An others choice
11199 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
11200 Iterated_Component_Association is not static.
11202 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11204 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
11205 control is passed to the expresion handler before the new mode
11207 * sem_ch12.adb (Analyze_Package_Instantiation,
11208 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set
11209 in case control is passed to the expresion handler before the
11212 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11214 * sem_aggr.adb, sem_ch3.adb, inline.adb, sem_util.adb, exp_ch4.adb,
11215 exp_aggr.adb: Minor reformatting.
11217 2017-01-13 Gary Dismukes <dismukes@adacore.com>
11219 * inline.adb: Minor reformatting and typo fix.
11221 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11223 * sem_util.ads, sem_util.adb (Choice_List): Move function here
11224 from sem_aggr.adb, for use elsewhere.
11225 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
11226 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
11227 Iterated_Component_Present.
11228 * exp_aggr.adb: Use Choice_List throughout, to handle
11229 Iterated_Component_Associations.
11230 (Gen_Loop): Generate proper loop for an
11231 Iterated_Component_Association: loop variable has the identifier
11232 of the original association. Generate a loop even for a single
11233 component choice, in order to make loop parameter visible in
11235 (Flatten): An Iterated_Component_Association is not static.
11237 2017-01-13 Yannick Moy <moy@adacore.com>
11239 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
11240 float exponentiation for statically known small negative values
11241 is the reciprocal of the exponentiation for the opposite value
11243 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
11244 Ensure that the value of float exponentiation for negative values
11245 is the reciprocal of the exponentiation for the opposite value
11247 * inline.adb (Expand_Inlined_Call): Fix the count
11248 for the number of generated gotos.
11250 2017-01-13 Yannick Moy <moy@adacore.com>
11252 * inline.adb: Code cleanup.
11253 * sem_util.adb (Is_OK_Volatile_Context): Add
11254 expression in delay statement as OK for volatile context.
11256 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11258 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
11259 mode a choice that is a subtype with a static predicate is
11260 replaced by the values it covers. This transformation must not
11261 be performed in ASIS mode, to preserve the source for analysis.
11263 2017-01-13 Justin Squirek <squirek@adacore.com>
11265 * nlists.ads: Correct minor typo.
11267 2017-01-13 Gary Dismukes <dismukes@adacore.com>
11269 * sem_ch13.adb: Minor reformatting and typo fix.
11271 2017-01-13 Ed Schonberg <schonberg@adacore.com>

11274 Iterated_Component_Association is a named association in an
11276 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
11277 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
11278 and resolve the discrete choices and the expression of the
11280 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
11281 Loop_Actions and Box_Present are attributes of
11282 N_Iterated_Component_Association nodes. Box_Present is always
11283 False in this case.
11284 * sprint.adb (Sprint_Node): An Iterated_Component_Association
11285 has a Discrete_Choices list, as specified in the RM. A
11286 Component_Association for aggregate uses instead a Choices list.
11287 We have to live with this small inconsistency because the new
11288 construct also has a defining identifier, and there is no way
11289 to merge the two node structures.
11291 2017-01-13 Yannick Moy <moy@adacore.com>
11293 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the
11294 list of pragmas to remove. Remove pragmas from the list of
11295 statements in the body to inline.
11296 * namet.adb, namet.ads (Nam_In): New version with 12 parameters.
11298 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11300 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
11301 Analyze_Declarations, to analyze and resolve the expressions of
11302 aspect specifications in the current declarative list, so that
11303 the expressions have proper entity and type info. This is needed
11304 for ASIS when there is no subsequent expansion to generate this
11305 semantic information.
11306 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
11307 original expression, to suppress cascaded errors when expression
11308 has been constant-folded.
11309 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
11310 ASIS mode, because there is no subsequent expansion to decorate
11313 2017-01-13 Yannick Moy <moy@adacore.com>
11315 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
11316 New function to detect when a call may be inlined or not in
11318 (Expand_Inlined_Call): Ensure that a temporary
11319 is always created in the cases where a type conversion may be
11320 needed on an input parameter in GNATprove mode, so that GNATprove
11321 sees the check to perform.
11322 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
11323 when not applicable due to actual requiring type conversion
11324 with possible check but no temporary value can be copied for
11325 GNATprove to see the check.
