3 * einfo.ads: Comment fix.
5 2017-12-15 Piotr Trojanek <trojanek@adacore.com>
7 * s-vercon.adb: Minor style fixes.
9 2017-12-15 Ed Schonberg <schonberg@adacore.com>
11 * sem_ch6.adb (Freeze_Expr_Types): Do not emit a freeze node for an
12 itype that is the type of a discriminant-dependent component.
14 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
16 * sem_prag.adb (Analyze_Part_Of): The context-specific portion of the
17 analysis is now directed to several specialized routines.
18 (Check_Part_Of_Abstract_State): New routine.
19 (Check_Part_Of_Concurrent_Type): New routine. Reimplement the checks
20 involving the item, the single concurrent type, and their respective
22 * sem_res.adb (Resolve_Entity_Name): Potential constituents of a single
23 concurrent type are now recorded regardless of the SPARK mode.
24 * sem_util.adb (Check_Part_Of_Reference): Split some of the tests in
25 individual predicates. A Part_Of reference is legal when it appears
26 within the statement list of the object's immediately enclosing
28 (Is_Enclosing_Package_Body): New routine.
29 (Is_Internal_Declaration_Or_Body): New routine.
30 (Is_Single_Declaration_Or_Body): New routine.

41 2017-12-15 Patrick Bernardi <bernardi@adacore.com>
43 * doc/gnat_ugn/gnat_and_program_execution.rst: Update section "Dynamic
44 Stack Usage Analysis" to include more details about GNAT_STACK_LIMIT.
46 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
48 * exp_util.adb (Add_Own_DIC): Ensure that the expression of the pragma
49 is available (Is_Verifiable_DIC_Pragma): Moved from Sem_Util.
50 * sem_util.adb (Has_Full_Default_Initialization):
51 Has_Fully_Default_Initializing_DIC_Pragma is now used to determine
52 whether a type has full default initialization due to pragma
53 Default_Initial_Condition.
54 (Has_Fully_Default_Initializing_DIC_Pragma): New routine.
55 (Is_Verifiable_DIC_Pragma): Moved to Exp_Util.
56 * sem_util.ads (Has_Fully_Default_Initializing_DIC_Pragma): New
58 (Is_Verifiable_DIC_Pragma): Moved to Exp_Util.
59 * sem_warn.adb (Is_OK_Fully_Initialized):
60 Has_Fully_Default_Initializing_DIC_Pragma is now used to determine
61 whether a type has full default initialization due to pragma
62 Default_Initial_Condition.
64 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
66 * sem_prag.adb (Match_Constituent): Do not quietly accept constants as
67 suitable constituents.
68 * exp_util.adb: Minor reformatting.
70 2017-12-15 Ed Schonberg <schonberg@adacore.com>
72 * exp_aggr.adb (In_Place_Assign_OK): Extend the predicate to recognize
73 an array aggregate in an allocator, when the designated type is
74 unconstrained and the upper bound of the aggregate belongs to the base
77 2017-12-15 Bob Duff <duff@adacore.com>
79 * exp_ch6.adb (Expand_N_Extended_Return_Statement,
80 Expand_Simple_Function_Return): Assert that the b-i-p-ness of the
81 caller and callee match. Otherwise, we would need some substantial
82 changes to allow b-i-p calls non-b-i-p, and vice versa.
84 2017-12-15 Ed Schonberg <schonberg@adacore.com>
86 * exp_unst.adb (Unnest_Subprograms): Nothing to do if the main unit is
87 a generic package body. Unnesting is only an issue when generating
88 code, and if the main unit is generic then nested instance bodies have
89 not been created and analyzed, and unnesting will crash in the absence
92 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
94 * inline.adb (Add_Inlined_Body): Do not add a function which is
95 completed by an expression function defined in the same context as the
96 initial declaration because the completing body is not in a package
98 (Is_Non_Loading_Expression_Function): New routine.
100 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
102 * debug.adb: Move the functionality of -gnatdL to -gnatd_i. Restore
103 the behavior of -gnatdL from before revision 255412.
104 * sem_elab.adb: Update the section of compiler switches.
105 (Build_Call_Marker): Do not create a marker for a call which originates
106 from an expanded spec or body of an instantiated gener, does not invoke
107 a generic formal subprogram, the target is external to the instance,
108 and -gnatdL is in effect.
109 (In_External_Context): New routine.
110 (Process_Conditional_ABE_Activation_Impl): Update the uses of -gnatdL
112 (Process_Conditional_ABE_Call): Update the uses of -gnatdL and
114 * switch-c.adb (Scan_Front_End_Switches): Switch -gnatJ now sets switch
116 * exp_unst.adb: Minor typo fixes and edits.
118 2017-12-15 Ed Schonberg <schonberg@adacore.com>
120 * sem_ch6.adb (Possible_Freeze): Do not set Delayed_Freeze on an
121 subprogram instantiation, now that the enclosing wrapper package
122 carries an explicit freeze node. THis prevents freeze nodes for the
123 subprogram for appearing in the wrong scope. This is relevant when the
124 generic subprogram has a private or incomplete formal type and the
125 instance appears within a package that declares the actual type for the
126 instantiation, and that type has itself a delayed freeze.
128 2017-12-15 Patrick Bernardi <bernardi@adacore.com>
130 * doc/gnat_ugn/gnat_and_program_execution.rst: Removed references to
131 the environment variable GNAT_STACK_LIMIT from the Stack Overflow
132 Checking section as it is no longer used by any of our supported
135 2017-12-15 Bob Duff <duff@adacore.com>
137 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
138 Init_Assignment is rewritten, we need to set Assignment_OK on the new
139 node. Otherwise, we will get spurious errors when initializing via
140 assignment statement.
142 2017-12-15 Arnaud Charlet <charlet@adacore.com>
144 * exp_unst.adb (Visit_Node): Refine handling of 'Access to ignore non
146 (Has_Non_Null_Statements): Moved to sem_util for later reuse.
148 2017-12-15 Eric Botcazou <ebotcazou@adacore.com>
150 * exp_attr.adb (Is_Inline_Floating_Point_Attribute): Fix comment.
151 * libgnat/s-fatgen.adb (Model): Use Machine attribute.
152 (Truncation): Likewise.
154 2017-12-15 Bob Duff <duff@adacore.com>
156 * exp_ch7.adb (Expand_Cleanup_Actions): Make sure the block and handled
157 statement sequence generated for certain extended return statements
158 have a Sloc that is not No_Location. Otherwise, the back end doesn't
159 set any location and ends up reading uninitialized variables.
161 2017-12-15 Bob Duff <duff@adacore.com>
163 * types.ads, exp_ch6.adb, libgnat/s-regexp.ads, opt.ads: Partly revert
164 r255414, committed by mistake.
166 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
168 * gcc-interface/Makefile.in: Generalize support for symbolic traces.
170 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
172 * gcc-interface/misc.c (default_pass_by_ref): Minor tweak.
174 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
176 * gcc-interface/trans.c (Call_to_gnu): Set DECL_DISREGARD_INLINE_LIMITS
177 to 0 on the callee if the call is recursive.
179 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
181 * gcc-interface/decl.c (gnat_to_gnu_field): Do not set the alignment
182 of the enclosing record type if it is not already set.
184 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
186 * gcc-interface/gigi.h (pad_type_has_rm_size): Declare.
187 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Do not build
188 a padding type for the alignment before validating the size.
189 Flip conditional construct and add a comment.
190 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Size>: Make sure to
191 apply the exception for padded objects to the type of the object.
192 * gcc-interface/utils.c (hash_pad_type): New static function.
193 (lookup_and_insert_pad_type): Rename into...
194 (canonicalize_pad_type): ...this. Call hash_pad_type, do only one
195 lookup with insertion and always return the canonical type.
196 (maybe_pad_type): Adjust to above changes. Set debug type later.
197 (pad_type_has_rm_size): New predicate.
198 (set_reverse_storage_order_on_pad_type): Adjust to above changes.
200 2017-12-13 Eric Botcazou <ebotcazou@adacore.com>
202 * gcc-interface/trans.c (Subprogram_Body_to_gnu): Initialize locus.
204 2017-12-13 Eric Botcazou <ebotcazou@adacore.com>
206 * gcc-interface/trans.c (process_freeze_entity): Be prepared for a
207 package without body.
209 2017-12-13 Eric Botcazou <ebotcazou@adacore.com>
211 * gcc-interface/decl.c (gnat_to_gnu_entity): Robustify test for types
212 descendant of System.Address.
213 (gnat_to_gnu_subprog_type): Likewise.
215 2017-12-08 Jakub Jelinek <jakub@redhat.com>
217 * gcc-interface/utils.c (gnat_internal_attribute_table): Add
218 exclusions to the comment.
220 2017-12-07 Martin Sebor <msebor@redhat.com>
223 * gcc-interface/utils.c (gnat_internal_attribute_table): Initialize
224 new member of struct attribute_spec.
226 2017-12-06 Simon Wright <simon@pushface.org>
229 * bindgen.adb (Gen_AdaFinal): If the restriction No_Task_Termination is
230 set, generate a null body.

234 * sem_util.adb (Contains_Refined_State): Remove.
236 2017-12-05 Ed Schonberg <schonberg@adacore.com>
238 * sem_ch13.adb (Analyze_Aspect_Specifications, case Predicate): A
239 predicate cannot apply to a formal type.
241 2017-12-05 Arnaud Charlet <charlet@adacore.com>
243 * exp_unst.ads: Fix typos.
245 2017-12-05 Jerome Lambourg <lambourg@adacore.com>
247 * libgnarl/s-taprop__qnx.adb: Better detect priority ceiling bug in
248 QNX. At startup, the first mutex created has a non-zero ceiling
249 priority whatever its actual policy. This makes some tests fail
250 (c940013 for example).
252 2017-12-05 Bob Duff <duff@adacore.com>
254 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Call
255 Expand_Cleanup_Actions for N_Extended_Return_Statement.
256 * exp_ch7.adb (Expand_Cleanup_Actions): Handle
257 N_Extended_Return_Statement by transforming the statements into a
258 block, and (indirectly) calling Expand_Cleanup_Actions on the block.
259 It's too hard for Expand_Cleanup_Actions to operate directly on the
260 N_Extended_Return_Statement, because it has a different structure than
261 the other node kinds that Expand_Cleanup_Actions.
262 * exp_util.adb (Requires_Cleanup_Actions): Add support for
263 N_Extended_Return_Statement. Change "when others => return False;" to
264 "when others => raise ...;" so it's clear what nodes this function
265 handles. Use named notation where appropriate.
266 * exp_util.ads: Mark incorrect comment with ???.
268 2017-12-05 Javier Miranda <miranda@adacore.com>
270 * exp_ch9.adb (Install_Private_Data_Declarations): Add missing
271 Debug_Info_Needed decoration of internally generated discriminal
272 renaming declaration.
274 2017-12-05 Arnaud Charlet <charlet@adacore.com>
276 * exp_unst.adb (Unnest_Subprogram): Add handling of 'Access on
279 2017-12-05 Sergey Rybin <rybin@adacore.com>
281 * doc/gnat_ugn/gnat_utility_programs.rst: Add description of '--ignore'
282 option for gnatmetric, gnatpp, gnat2xml, and gnattest.
284 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
286 * sem_util.adb (Contains_Refined_State): Remove.
288 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
290 * rtsfind.ads: Add new enumeration literals: RE_Clock_Time (for
291 Ada.Real_Time.Clock_Time) and RO_CA_Clock_Time (for
292 Ada.Calendar.Clock_Time).
294 2017-12-05 Ed Schonberg <schonberg@adacore.com>
296 * sem_ch4.adb (Is_Private_Overriding): If the candidate private
297 subprogram is overloaded, scan the list of homonyms in the same
298 scope, to find the inherited operation that may be overridden
300 * exp_ch11.adb, exp_ch7.adb: Minor reformatting.
302 2017-12-05 Bob Duff <duff@adacore.com>
304 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
305 Init_Assignment is rewritten, we need to set Assignment_OK on the new
306 node. Otherwise, we will get spurious errors when initializing via
307 assignment statement.
309 2017-12-05 Hristian Kirtchev <kirtchev@adacore.com>
311 * sem_elab.adb: Update the terminology and switch sections.
312 (Check_SPARK_Model_In_Effect): New routine.
313 (Check_SPARK_Scenario): Verify the model in effect for SPARK.
314 (Process_Conditional_ABE_Call_SPARK): Verify the model in effect for
316 (Process_Conditional_ABE_Instantiation_SPARK): Verify the model in
318 (Process_Conditional_ABE_Variable_Assignment_SPARK): Verify the model
321 2017-12-05 Nicolas Setton <setton@adacore.com>
323 * terminals.c (__gnat_setup_child_communication): As documented,
324 __gnat_setup_child_communication should not terminate - it is intended
325 to be used as the child process of a call to fork(). However, execvp
326 might actually return in some cases, for instance when attempting to
327 run a 32-bit binary on a 64-bit Linux distribution when the
328 compatibility packages are not installed. In these cases, exit the
329 program to conform to the documentation.
331 2017-12-05 Olivier Hainque <hainque@adacore.com>
333 * libgnat/s-tsmona.adb: Fix for oversight in the tsmona interface

345 on access to subprogram types with foreign convention.
347 2017-12-05 Yannick Moy <moy@adacore.com>
349 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Fix User's
350 Guide description of default settings of warnings.
352 2017-12-05 Olivier Hainque <hainque@adacore.com>
354 * s-dwalin.adb (Read_And_Execute_Isn): Adjust test checking for the end
355 of section. Add comments explaining the rationale of the computation.
357 2017-12-05 Bob Duff <duff@adacore.com>

403 switches. Update the documentation on adding a new target. Add
404 Processing_Attributes which represent the state of the Processing
405 phase. Resurrect the previous elaboration model as "legacy elaboration
407 (Build_Call_Marker): This routine does not function when the legacy
408 elaboration model is in effect. Do not consider entry calls and requeue
409 statements when debug flag d_e is in effect. Do not consider calls to
410 subprograms which verify the runtime semantics of certain assertion
411 pragmas when debug flag d_p is in effect.
412 (Build_Variable_Reference_Marker): This routine does not function when
413 the legacy elaboration model is in effect.
414 (Check_Elaboration_Scenarios): This routine does not function when the
415 legacy elaboration model is in effect.
416 (Ensure_Prior_Elaboration): The various flags have now been replaced
417 with a state. Do not generate implicit Elaborate[_All] pragmas when
418 their creation has been suppressed.
419 (Ensure_Prior_Elaboration_Static): The with clause is marked based on
420 the requested pragma, not on the nature of the scenario.
421 (In_External_Context): Removed.
422 (Is_Assertion_Pragma_Target): New routine.
423 (Is_Potential_Scenario): Stop the traversal of a task body when
424 reaching an accept or select statement, and debug switch d_a is in
426 (Kill_Elaboration_Scenario): This routine does not function when the
427 legacy elaboration model is in effect.

432 (Process_Conditional_ABE_Access): The various flags have now been
433 replaced with a state.
434 (Process_Conditional_ABE_Activation_Impl): The various flags have now
435 been replaced with a state. Do not process an activation call which

437 debug switch dL is in effect. Suppress the generation of implicit
438 Elaborate[_All] pragmas once a conditional ABE check has been
440 (Process_Conditional_ABE_Call): The various flags have now been
441 replaced with a state. Do not process a call which invokes a subprogram
442 defined in an external instance, and debug switch dL is in effect.

444 replaced with a state. Suppress the generation of implicit
445 Elaborate[_All] pragmas once a conditional ABE check has been
447 (Process_Conditional_ABE_Call_SPARK): The various flags have now been
448 replaced with a state.

492 Improve doc on required packages for linux 32bits.
494 2017-12-05 Doug Rupp <rupp@adacore.com>
496 * tracebak.c (ppc64-vx7): USE_GCC_UNWINDER for 64bit.
498 2017-12-05 Javier Miranda <miranda@adacore.com>
500 * checks.adb (Generate_Range_Check): Force evaluation of the node in
501 more cases. This patch was written to improve the code generated by
502 the CCG compiler but it is enabled for all targets since double
503 evaluation is always a potential source of inefficiency.
505 2017-12-05 Gary Dismukes <dismukes@adacore.com>
507 * doc/gnat_ugn/gnat_utility_programs.rst: Remove reference to obsolete
510 2017-12-05 Eric Botcazou <ebotcazou@adacore.com>
512 * exp_ch5.adb (Expand_Iterator_Loop_Over_Array): Use the SLOC of the
513 iteration scheme throughout, except for the new loop statement(s).
515 2017-12-05 Ed Schonberg <schonberg@adacore.com>
517 * exp_aggr.adb (Gen_Assign): Do not analyze the expressionn of the
518 assignment if it is part of an Iterated_Component_Association: the
519 analysis needs to take place once the loop structure is analyzed and
520 the loop parameter made visible, because references to it typically
521 appear in the corresponding expression. This is necessary if the
522 expression is an aggregate, because previous pre-analysis of the
523 expression does not handle nested aggregates properly.
525 2017-12-05 Bob Duff <duff@adacore.com>
527 * sem_res.adb (Resolve_Allocator): Avoid coextension processing for an
528 allocator that is the expansion of a build-in-place function call.
530 2017-12-05 Olivier Hainque <hainque@adacore.com>
533 * s-trasym__dwarf.adb (spec of Module_Name.Get): Instead of
534 possibly adjusting the lookup address by a load address, expect
535 a extra argument through which the load address can be conveyed
537 (Multi_Module_Symbolic_Traceback): Adjust accordingly. Pass the
538 retrieved load address to Init_Module.

1058 * libgnarl/s-taprop__mingw.adb: On Windows, initialize the thead handle
1059 only for foreign threads. We initialize the thread handle only if not
1060 yet initialized. This happens in Enter_Task for foreign threads only.
1061 But for native threads (Ada tasking) we do want to keep the real
1062 handle (from Create_Task) to be able to free the corresponding
1063 resources in Finalize_TCB (CloseHandle).
1065 2017-11-09 Yannick Moy <moy@adacore.com>
1067 * sem_attr.adb (Analyze_Attribute): Default initialize P_Type,

1076 dispatch table is statically built.
1077 (Make_DT): Declare constant the Interface_Table object associated with
1078 an statically built dispatch table. For this purpose the Offset_To_Top
1079 value of each interface is computed using the dummy object.
1080 * exp_ch3.adb (Build_Init_Procedure): Do not generate code initializing
1081 the Offset_To_Top field of secondary dispatch tables when the dispatch
1082 table is statically built.
1083 (Initialize_Tag): Do not generate calls to Register_Interface_Offset
1084 when the dispatch table is statically built.

1092 to avoid a dormant bug.
1094 2017-11-09 Jerome Lambourg <lambourg@adacore.com>
1096 * init.c: Define missing __gnat_alternate_stack for QNX. Set it to 0,
1097 as such capability is not available on the OS.
1098 * link.c: Make sure linker options for QNX are correct.
1099 * libgnarl/s-osinte__qnx.ads: Add some missing bindings to pthread.
1100 * libgnarl/s-taprop__qnx.adb: New, derived from s-taprop__posix.adb. This brings
1101 in particular a workaround with locks priority ceiling where a higher
1102 priority task is allowed to lock a lower ceiling priority lock. This
1103 also fixes the scheduling of FIFO tasks when the priority of a task is
1105 * libgnat/system-qnx-aarch64.ads: Fix priority ranges.
1107 2017-11-09 Yannick Moy <moy@adacore.com>

1111 * gnatbind.adb (Scan_Bind_Arg): Simplify test to remove always true
1113 * namet.adb (Copy_One_Character): Add assumption for static analysis,
1114 as knowledge that Hex(2) is in the range 0..255 is too complex for
1116 (Finalize): Add assumption for static analysis, as the fact that there
1117 are symbols in the table depends on a global invariant at this point in
1119 * set_targ.adb (Check_Spaces): Justify CodePeer false positive message.
1120 * stylesw.adb (Save_Style_Check_Options): Rewrite to avoid test always
1123 2017-11-09 Javier Miranda <miranda@adacore.com>
1125 * libgnat/s-rident.ads (Static_Dispatch_Tables): New restriction name.
1126 * exp_disp.adb (Building_Static_DT): Check restriction.
1127 (Building_Static_Secondary_DT): Check restriction.
1128 (Make_DT): Initialize the HT_Link to No_Tag.
1129 * opt.ads (Static_Dispatch_Tables): Rename flag...

1163 * exp_util.adb (Find_Interface_Tag): Default initialize AI_Tag.
1164 * freeze.adb (Check_Component_Storage_Order): Default initialize
1165 Comp_Byte_Aligned rather than silencing messages with pragma
1166 Warnings(Off), which does not work for CodePeer initialization
1167 messages, and given that here the possible read of an unitialized value
1168 depends on a proper use of parameters by the caller.
1169 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.
1170 * sem_ch12.adb (Build_Operator_Wrapper): Default initialize Expr.

1176 Others_Present is set by the call to Check_Choices.
1177 * sem_ch5.adb (Analyze_Assignment): Default initialize
1179 * sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,
1180 and restructure code to defend against previous errors, so that, in
1181 that case, control does not flow to the elsif condition which read an
1182 uninitialized Obj_Decl.
1183 * sem_ch9.adb (Analyze_Requeue): Default initialize Synch_Type.
1184 (Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
1185 which seem to be left uninitialized and possibly read in some cases.
1186 * sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more
1187 precisely. This requires to exchange the test for exiting in case of
1188 too many positions and the increment to Position, inside the loop.
1189 * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,
1190 which cannot be read uninitialized, but the reasons for that are quite
1192 * sem_intr.adb (Check_Intrinsic_Call): Default initialize Rtyp.
1193 * sem_prag.adb (Collect_Subprogram_Inputs_Outputs): Default initialize
1195 * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
1196 and test for presence of non-null Opnd_Type before testing its scope,
1197 in a test which would read its value uninitialized, and is very rarely
1198 exercized (it depends on the presence of an extension of System).
1199 * sem_spark.ads: Update comment to fix name of main analysis procedure.
1200 * sem_warn.adb (Warn_On_Known_Condition): Default initialize
1202 * set_targ.adb (FailN): Mark procedure with No_Return.
1203 * stylesw.adb (Save_Style_Check_Options): Delete useless code to
1204 initialize all array Options to white space, as there is already code
1205 doing the same for the remaining positions in Options at the end of the

1210 * exp_ch11.adb (Possible_Local_Raise): Do not issue the warning for

1215 * sem_prag.adb (Analyze_Part_Of): Reword error message.
1216 (Get_SPARK_Mode_Type): Do not raise Program_Error in case pragma

1229 * sem_ch8.adb (Analyze_Use_Package): Force installation of use_clauses
1230 when processing generic instances.
1232 2017-11-09 Bob Duff <duff@adacore.com>
1234 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
1235 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
1236 objects can have those special values. Valid_Name_Id could usefully be
1237 used all over the compiler front end, but that's too much trouble for
1238 now. If we did that, we might want to rename:
1239 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
1240 For parameters of type Valid_Name_Id, remove some redundant tests,
1241 including the ones found by CodePeer. Use Is_Valid_Name instead of
1242 membership test when appropriate.
1243 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
1244 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
1245 "in Error_Name_Or_No_Name".
1246 (Check_Parameterless_Call): Use "not Is_Valid_Name" instead of "in
1247 Error_Name_Or_No_Name".

1258 * lib-writ.adb (Write_ALI): Remove processing of the frontend xrefs as
1259 part of the ALI writing; they are now processed directly from memory

1321 Set_Static_Offset_To_Top passing a negative offet-to-top value;
1322 initialize also the offset-to-top field with a negative offset.
1323 * libgnat/a-tags.adb (Base_Address): Displace the pointer by means of
1324 an addition since the offset-to-top field is now a negative value.

2611 * exp_ch6.adb: (Make_Build_In_Place_Call_In_Object_Declaration): Take

2641 * sem_util.adb (Object_Access_Level): If the object is the return
2642 statement of an expression function, return the level of the function.
2643 This is relevant when the object involves an implicit conversion
2644 between access types and the expression function is a completion, which
2645 forces the analysis of the expression before rewriting it as a body, so
2646 that freeze nodes can appear in the proper scope.

2671 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking
2672 code so if BIPAlloc is not passed in, it will likely raise
2673 Program_Error instead of cause miscellaneous chaos.

2675 as for the other Is_B-I-P... functions.

2681 creating an Itype for a library unit entity.

2683 internally-generated call.
2684 * sem_ch5.adb (Analyze_Assignment): Handle the case where the

2686 was only for limited types.
2687 * sem_ch6.adb (Create_Extra_Formals): Remove assumption that b-i-p
2688 implies >= Ada 2005.

2717 actual for a formal package is an instantiation of a child unit, create
2718 a freeze node for the instance of the parent if it appears in the same
2719 scope and is not frozen yet.
2721 2017-10-09 Pierre-Marie de Rodat <derodat@adacore.com>
2723 * exp_atag.ads, libgnat/a-tags.adb, libgnat/a-tags.ads: Enhance
2724 in-source documentation for tagged types's Offset_To_Top.
2726 2017-10-09 Bob Duff <duff@adacore.com>
2728 * exp_ch3.adb (Build_Assignment): Parameter name N was somewhat
2729 confusing. Same for N_Loc. Remove assumption that b-i-p implies
2730 limited. This is for the case of a function call that occurs as the
2731 default for a record component.
2732 (Expand_N_Object_Declaration): Deal with the case where expansion has
2733 created an object declaration initialized with something like

2739 * exp_attr.adb (Expand_Attribute_Reference, case 'Valid): The prefix of
2740 the attribute is an object, but it may appear within a conversion. The
2741 object itself must be retrieved when generating the range test that
2742 implements the validity check on a scalar type.

2803 (Is_Build_In_Place_Result_Type): New function to accompany
2804 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
2805 sometimes we just have the type on our hands, not the function. For
2806 now, does the same thing as the old version, so build-in-place is
2807 disabled for nonlimited types, except that you can use -gnatd.9 to

2810 accompany Is_Build_In_Place_Function and

2824 an unchecked conversion. Add assertions.

3839 2017-09-08 Yannick Moy <moy@adacore.com>
3841 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
3842 return the entity associated with the call.
3843 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
3844 Replace the internal Get_Function_Id with the new
3845 Sem_Aux.Get_Called_Entity.
3846 (Iterate_Call_Parameters): New
3847 procedure to iterate on formals and actuals at the same time.
3848 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
3849 Set SPARK_Mode from spec when set, for analysis
3850 of instance. Restore after analysis of instance.
3851 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
3852 set, for analysis of body instance. Restored automatically at
3853 the end of the subprogram.
3854 * gnat1drv.adb (Adjust_Global_Switches): Set
3855 Check_Validity_Of_Parameters to False in GNATprove mode.
3856 * opt.ads (Check_Validity_Of_Parameters): Document switch to

3861 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
3862 (New_Copy_Tree): ...there. Reset the hash tables only if they
3863 were used in the previous invocation.
3864 * s-htable.adb: Fix typo.
3866 2017-09-08 Bob Duff <duff@adacore.com>
3868 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
3870 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3872 * sem_aggr.adb: minor style fix.
3874 2017-09-08 Bob Duff <duff@adacore.com>
3876 * sprint.adb (Write_Corresponding_Source): Ignore if there is
3877 no current source file.

3879 Print something helpful in case N is invalid.
3880 * sprint.ads: Minor comment fix.
3882 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3884 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
3887 2017-09-08 Bob Duff <duff@adacore.com>
3889 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
3890 Ada_2020, along the same lines as the other Ada version pragmas.
3892 2017-09-08 Gary Dismukes <dismukes@adacore.com>
3894 * sem_ch12.adb: Minor typo fixes and reformatting.
3896 2017-09-08 Yannick Moy <moy@adacore.com>
3898 * sem_aggr.adb (Resolve_Record_Aggregate):
3899 Rewrite bounds of aggregate subexpressions which may depend on
3900 discriminants of the enclosing aggregate.
3902 2017-09-08 Yannick Moy <moy@adacore.com>
3904 * sem_ch5.adb: Prevent assertion failure on illegal code.
3906 2017-09-08 Yannick Moy <moy@adacore.com>
3908 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
3909 calling Renamed_Entity on an entity which cannot be a renaming.
3911 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3913 * exp_aggr.adb: Add with & use clause for Urealp.
3914 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
3915 elementary types instead of just discrete types.
3916 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
3917 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
3918 Be prepared for the FP zero value in the memset case. Add small
3921 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3923 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
3926 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3928 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
3929 of New_Copy because the latter leaves the syntactic structure of
3930 the tree inconsistent (a child is accessible through two parents)
3931 and prevents proper replication of itypes by subsequent calls
3933 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
3934 New_Copy because the latter leaves the syntactic structure of the
3935 tree inconsistent (a child is accessible through two parents)

3945 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
3946 for aspect Default_Value is a static scalar value, but it does
3947 not freeze the type. Yhis allows for subsequent representation
3948 clauses for the type.
3950 2017-09-08 Javier Miranda <miranda@adacore.com>
3952 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
3953 not add entries into the undefined reference table when we are
3954 compiling with errors ignored.
3956 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3958 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
3959 check if the instance is within an enclosing instance body. The
3960 formal package was legal in the enclosing generic, and is
3961 legal in the enclosing instantiation. This optimisation may be
3962 applicable elsewhere, and it also removes spurious errors that
3963 may arise with on-the-fly processing of instantiations that
3964 contain Inline_Always subprograms.
3966 2017-09-08 Vincent Celier <celier@adacore.com>
3968 * gnatcmd.adb: Disregard empty argument of GNAT driver.
3970 2017-09-08 Justin Squirek <squirek@adacore.com>
3972 * checks.adb (Insert_Valid_Check): Manually decorate
3973 the generated temporary for range valdity checks.
3975 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3977 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
3979 2017-09-08 Justin Squirek <squirek@adacore.com>
3981 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
3982 case to handle underscore flags.
3983 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create

4407 (In_Package_Spec): previously In_Package_Visible_Spec; now
4408 detects subprograms declared both in visible and private parts
4411 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4413 * exp_util.adb (Build_Invariant_Procedure_Declaration): If
4414 the type is an anonymous array in an object declaration, whose
4415 component type has an invariant, use the object declaration
4416 as the insertion point for the invariant procedure, given that
4417 there is no explicit type declaration for an anonymous array type.
4419 2017-09-08 Bob Duff <duff@adacore.com>
4421 * a-cbprqu.ads, a-cbdlli.adb: Suppress warnings.

4430 source file is missing.
4432 2017-09-08 Bob Duff <duff@adacore.com>
4435 * a-textio.adb, a-witeio.adb, a-ztexio.adb (Set_WCEM): Use
4436 Default_WCEM by default (i.e. if the encoding is not specified
4437 by the Form string).
4439 2017-09-08 Bob Duff <duff@adacore.com>
4441 * s-trasym.ads (Hexa_Traceback): If
4442 Suppress_Hex is True, print "..." instead of a hexadecimal
4444 * s-trasym.adb: Ignore No_Hex in this version.
4447 2017-09-08 Bob Duff <duff@adacore.com>
4449 * debug.adb: Minor reformatting.
4451 2017-09-08 Bob Duff <duff@adacore.com>
4453 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
4454 code so it doesn't trigger an "uninit var" warning.
4456 2017-09-08 Nicolas Roche <roche@adacore.com>
4458 * s-hibaen.ads: Remove obsolete file.
4460 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4462 * a-locale.ads: Add comment explaining the state of this package.
4464 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4466 * sem_util.adb (Is_CCT_Instance): Allow calls in the context
4468 * sem_prag.ads, sem_prag.adb (Find_Related_Declaration_Or_Body):
4469 allow calls in the context of package spec (for pragma
4470 Initializes) and bodies (for pragma Refined_State).
4472 2017-09-08 Bob Duff <duff@adacore.com>
4474 * checks.adb (Insert_Valid_Check): Copy the Do_Range_Check flag to the
4477 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4479 * debug.adb (dA): Adjust comment.
4480 * gnat1drv.adb (Gnat1drv): Likewise.
4481 * opt.ads (List_Representation_Info_Extended): New variable.
4482 * repinfo.adb (List_Record_Info): Split implementation into...
4483 (Compute_Max_Length): ...this. Recurse on records if requested.
4484 (List_Record_Layout): Likewise.
4485 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
4486 statement, accept '0' and set List_Representation_Info_Extended
4488 * usage.adb (Usage): Document new -gnatRe variant.
4490 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4492 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
4493 Do not save the given entity in the global variable Default_Pool
4494 if the pragma appears within a generic unit.
4496 2017-09-08 Bob Duff <duff@adacore.com>
4498 * errout.adb (Delete_Warning): Do not
4499 decrement Warnings_Treated_As_Errors. This is called before
4500 Warnings_Treated_As_Errors has been incremented to account for
4501 this warning. Decrementing it here can lead to negative values
4502 of Warnings_Treated_As_Errors, raising Constraint_Error in
4503 checks-on builds, and causing the compiler to return an error
4504 code in checks-off builds.
4506 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4508 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
4509 entities of named concurrent types as Ref_Id and not of anonymous
4510 concurrent objects (because callers already know when a conversion
4511 is necessary and can easily do it); also, do not expect protected
4512 types or protected objects as Context_Id (because no flow-related
4513 SPARK pragmas are attached there); reflect these changes in a
4514 more precise comment.
4516 2017-09-08 Olivier Hainque <hainque@adacore.com>
4518 * g-altive.ads: Add documentation.
4520 2017-09-08 Bob Duff <duff@adacore.com>
4522 * sem_util.ads, debug.adb: Minor comment fix.
4523 * erroutc.ads: Comment fix.
4525 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4527 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
4528 for compatibility of component types of formal and actual in an
4529 instantiation of a child unit, when the component type of the
4530 formal is itself a formal of an enclosing generic.
4532 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4534 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
4535 sem_prag.adb to make it available for GNATprove; for concurrent
4536 types replace custom scope climbing with Scope_Same_Or_Within; for
4537 single concurrent objects add scope climbing (with Scope_Within),
4538 which was not there (that's the primary semantic change of this
4539 commit); also, when comparing a single concurrent object with
4540 its corresponding concurrent type rely on equality of types,
4541 not of objects (because that's simpler to code).
4542 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
4543 (Analyze_Global_Item): adjust special-casing of references to the
4544 current instance of a concurrent unit in the Global contracts
4545 of task types and single tasks objects; similar for references
4546 in the protected operations and entries of protected types and
4547 single protected objects (in all these cases the current instance
4548 behaves as an implicit parameter and must not be mentioned in
4549 the Global contract).
4551 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4553 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
4554 function calls returning a record within a subprogram call,
4557 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4559 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
4560 name that designates the current instance of a child unit in its
4561 own body and appears as the prefix of a reference to an entity
4562 local to the child unit.
4563 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
4566 2017-09-08 Yannick Moy <moy@adacore.com>
4568 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that

4573 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
4574 warnings on internal units in configurable run time mode.
4576 2017-09-08 Bob Duff <duff@adacore.com>
4578 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
4579 representation items from interfaces that the derived type
4580 implements, not just from the parent type.
4581 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
4582 this to return an empty list when there are no interfaces.
4583 * einfo.ads, sem_ch13.adb: Minor comment fixes.
4584 * sem_attr.adb: Minor comment fix.
4586 2017-09-08 Doug Rupp <rupp@adacore.com>

4593 * exp_ch4.adb (Expand_N_Allocator): Generate a
4594 call to Allocate_Any_Controlled when the allocation does not
4595 require any initialization.
4597 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4599 * sem_util.adb (Copy_Node_With_Replacement):
4600 Update the Renamed_Object field of a replicated object renaming
4603 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
4605 * exp_ch9.adb (Is_Pure_Barrier): Allow type
4606 conversions and components of objects. Simplified the detection
4607 of the Count attribute by identifying the corresponding run-time
4610 2017-09-08 Yannick Moy <moy@adacore.com>
4612 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
4613 sem_type.adb, sinfo.ads: Minor reformatting.
4615 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4617 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
4618 of Freeze_Profile, used to inhibit the freezing of the profile
4619 of an expression function declared within a nested package, when
4620 some type in the profile depends on a private type declared in
4621 an enclosing package.
4623 2017-09-08 Bob Duff <duff@adacore.com>
4625 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
4626 the subunit case. It's still OK to set it in the "missing subunits"
4627 case, because that won't cause the obsolete .ali files that cause
4630 2017-09-08 Bob Duff <duff@adacore.com>
4632 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
4633 unclear why this didn't cause a warning.
4634 * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
4635 pragmas. It's unclear why this didn't cause an error.
4637 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4639 * exp_spark.adb (Expand_SPARK_N_Object_Renaming_Declaration):
4641 (Expand_SPARK_Potential_Renaming): Code clean up.
4642 * sem_prag.adb (Analyze_Initialization_Item): Add a guard in case
4643 the item does not have a proper entity.

4661 * repinfo.adb (List_Record_Info): During first loop,
4662 do not override the normalized position and first bit
4663 if they have already been set. Move fallback code
4664 for the packed case to the case where it belongs.
4665 * sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
4666 Also adjust the normalized position of components.
4667 (Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise.
4669 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4671 * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
4672 the placement of a primitive operation O that renames an operation
4673 R declared in an inner package, and which is thus not a primitive
4674 of the dispatching type of O. In this case O is a new primitive
4675 and does not inherit its dispatch table position from R (which

4680 * sem_dim.adb (Analyze_Dimension_If_Expression,
4681 Analyze_Dimension_Case_Expression): new subprograms to verify
4682 the dimensional correctness of Ada2012 conditional expressions,
4683 and set properly the dimensions of the construct.
4684 * sem_res.adb (Resolve_If_Expression, Resolve_Case_Expression)):
4685 call Analyze_Dimension.

4689 * sem_type.adb (Expand_Interface_Conversion): Prevent an infinite
4690 loop on an interface declared as a private extension of another
4691 synchronized interface.

4695 * sem_ch12.adb (Check_Generic_Parent): New procedure within
4696 Analyze_Associations, to handle actual packages that depend on
4697 previous instances. If a package IAP that is an instantiation is
4698 used as an actual in a subsequent instantiation SI in the same
4699 scope, and IAP has a body, IAP must be frozen before SI. If
4700 the generic parent of IAP is itself declared in a previous
4701 instantiation in the same scope, that instantiation must also
4702 be frozen before SI.
4703 (Install_Body): Prevent double insertion of freeze node for
4706 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>

4714 * sem_ch13.adb (Analyze_Aspect_Specifications, case
4715 Linker_Section): If the aspect applies to an object declaration
4716 with explicit initialization, do not delay the freezing of the
4717 object, to prevent access-before-elaboration in the generated
4718 initialization code.
4720 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4722 * a-wtdeio.adb (Put, all versions): Use Long_Long_Integer
4723 (Integer_Value (Item)) when the size of the fixed decimal type
4724 is larger than Integer.
4726 2017-09-07 Eric Botcazou <ebotcazou@adacore.com>
4729 * gcc-interface/decl.c (copy_and_substitute_in_layout): Put the fields
4730 in order of increasing position in more cases.

4758 in the external name of the elaboration flag. Required to fix
4759 the regressions introduced by the initial version of this patch.
4761 2017-09-07 Bob Duff <duff@adacore.com>
4763 * sem_ch6.adb (Analyze_Function_Return): Do not
4764 insert an explicit conversion to force the displacement of the
4765 "this" pointer to reference the secondary dispatch table in the
4766 case where the return statement is returning a raise expression,
4767 as in "return raise ...".

4791 to handle properly various cases of type conversions where the
4792 target type and/or the expression carry dimension information.
4793 (Dimension_System_Root); If a subtype carries dimension
4794 information, obtain the source parent type that carries the

4803 * exp_attr.adb (Expand_N_Attribute_Reference, case 'Constrained):
4804 If the prefix is a reference to an object, rewrite it as an
4805 explicit dereference, as required by 3.7.2 (2) and as is done
4806 with most other attributes whose prefix is an access value.
4808 2017-09-07 Bob Duff <duff@adacore.com>

4870 clause for a unit U appears in a context that includes a regular
4871 with_clause on U, rewrite the redundant private clause into a null
4872 statement, rather than removing it altogether from the context,
4873 so that ASIS tools can reconstruct the original source.

4877 * sem_ch13.adb (Check_Aspect_At_Freeze_Point): The expression

4927 * exp_ch3.adb (Build_Init_Procedure): Improve the code
4928 generated in the IP routines by means of keeping separate
4929 the initialization of the object components from the

4934 because the type of one of its formals has been changed.
4935 * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
4936 modified. Instead of receiving a pointer to an object this
4937 routine receives now a primary tag.
4938 (Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
4939 additional formal: the tag of the primary dispatch table.
4940 * exp_disp.ads (Elab_Flag_Needed): New subprogram.
4941 * exp_disp.adb (Elab_Flag_Needed): New subprogram.

4951 applied to generic subprograms.
4953 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4955 * sem_util.adb (Check_Part_Of_Reference): rename Conc_Typ to Conc_Obj
4956 (because it refers to the anonymous concurrent object, not its type);
4957 fix condition for emitting error message about task/protected type,
4959 2017-09-07 Bob Duff <duff@adacore.com>
4961 * binde.adb (Debug_Flag_Old): If both -do and -dp
4962 are specified, behave as if just -do was specified, rather than

4970 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4972 * sem_prag.adb (Find_Role): The Global_Seen flag
4973 is now consulted not only for abstract states and variables,
4974 but for all kinds of items.
4975 (Collect_Subprogram_Inputs_Outputs): Do not process formal
4976 generic parameters, because unlike ordinary formal parameters,
4977 generic formals only act as input/ outputs if they are explicitly
4978 mentioned in a Global contract.
4980 2017-09-07 Yannick Moy <moy@adacore.com>
4982 * ghost.adb (Check_Ghost_Context): Do not err on ghost code inside
4983 predicate procedure. Check predicate pragma/aspect with Ghost entity.
4984 * exp_ch6.adb, par-ch6.adb, sem_ch13.adb, sem_prag.adb; Minor
4987 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4989 * sem_aggr.adb: Move New_Copy_Tree_And_Dimensions to sem_dim
4991 * sem_ch3.adb (Build_Derived_Record_Type):i Call
4992 Copy_Dimensions_Of_Components after creating the copy of the
4994 * sem_dim.ads, sem_dim.adb (Copy_Dimensions_Of_Components): For a
4995 derived recor type, copy the dikensions if any of each component
4996 of the parent record to the corresponding component declarations
4997 of the derived record. These expressions are used among other
4998 things as default values in aggregates with box associations.
4999 * a-dirval-mingw.adb, g-cgi.adb, gnatcmd.adb, lib-xref.adb,
5000 repinfo.adb, sem_attr.adb, sem_ch10.adb, sem_ch6.adb, sem_prag.adb:

5010 also mark the renamed subprogram as referenced.
5012 2017-09-07 Ed Schonberg <schonberg@adacore.com>
5014 * par-ch6.adb (P_Subprogram): Improve error message on null
5015 procedure with misplaced aspect specification, which the parser
5016 first attempts to interpret as a malformed expression function.
5018 2017-09-07 Gary Dismukes <dismukes@adacore.com>
5020 * sem_attr.adb (Analyze_Attribute_Old_Result):
5021 Allow attributes Result and Old in the case of an expression

5043 Make_Build_In_Place_Call_In_Anonymous_Context): Do not use the
5044 secondary stack for all functions that return limited tagged
5045 types -- just do it for dispatching calls. Misc cleanup.
5046 * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
5047 remove qualifications and type conversions. Fix various bugs
5048 where only a single level of qualification or conversion was
5049 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
5051 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
5054 2017-09-07 Ed Schonberg <schonberg@adacore.com>
5056 * sem_ch6.adb (setr_Actual_Subtypes): Within a predicate function
5057 do not create actual subtypes that may generate further predicate
5059 * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
5060 of body is a predicate function as well.
5061 (Resolve_Aspect_Expressions, Resolve_Name): For a component
5062 association, only the expression needs resolution, not the name.
5063 (Resolve_Aspect_Expressions, case Predicates): Construct and
5064 analyze the predicate function declaration in the scope of the
5065 type, before making the type and its discriminants visible.
5067 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
5069 * gcc-interface/decl.c (warn_on_field_placement): Issue the warning
5070 only if the record type itself comes from source.

5101 2017-09-06 Bob Duff <duff@adacore.com>
5103 * sem_ch8.adb: Change Assert to be consistent with
5106 2017-09-06 Bob Duff <duff@adacore.com>
5108 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
5109 requested. Previously, the -do switch meant "run Elab_New and
5110 Elab_Old and use the order chosen by Elab_Old, possibly with
5111 debugging printouts comparing the two orders." Now it means
5112 "do not run Elab_New." This is of use if there are bugs that
5113 cause Elab_New to crash.
5114 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
5116 * ali.ads (Elab_Position): Change type to Nat, to avoid various

5130 * freeze.adb (Freeze_Record_Type)
5131 <Sized_Component_Total_Round_RM_Size>: New local variable to
5132 accumulate the rounded RM_Size of components. Update it for
5133 every component whose RM_Size is statically known. Add missing
5134 guard to check that bit packing is really required before issuing
5135 the error about packing. Swap condition for clarity's sake.
5136 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.

5155 project manager sources.
5157 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5159 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
5160 entity of a mutable type and the right-hand side is a conditional
5161 expression, resolve the alternatives of the conditional using
5162 the base type of the target entity, because the alternatives
5163 may have distinct subtypes. This is particularly relevant if
5164 the alternatives are aggregates.
5166 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5168 * checks.adb (Apply_Predicate_Check): If the expression is an
5169 aggregate that is the RHS of an assignment, apply the check to
5170 the LHS after the assignment, rather than to the aggregate. This
5171 is more efficient than creating a temporary for the aggregate,
5172 and prevents back-end crashes when the aggregate includes a
5173 dynamic "others' association.
5175 2017-09-06 Yannick Moy <moy@adacore.com>
5177 * sem_ch12.adb (Analyze_Instance_And_Renamings):

5185 seen and is candidate for inlining.

5189 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.

5193 2017-09-06 Gary Dismukes <dismukes@adacore.com>
5195 * errout.adb (Error_Msg): Separate the
5196 treatment for warning vs. style messages in inlinings and
5197 instantiations. Prevents blowups on calls to Warn_Insertion for
5198 style messages, which should not be called in that case because
5199 Warning_Msg_Char is not set.
5201 2017-09-06 Justin Squirek <squirek@adacore.com>
5203 * sem_prag.adb (Check_VFA_Conflicts): Created
5204 to group all Volatile_Full_Access checks relating to other
5205 representation pragmas (Mark_Component_Or_Object): Created
5206 to centeralize the flagging of attributes for the record type
5207 component case, a pragma applied individually to a component, and
5209 (Process_Atomic_Independent_Shared_Volatile):

5224 2017-09-06 Bob Duff <duff@adacore.com>
5226 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
5227 that is a proper body corresponding to a stub, we defer the
5228 adjustment of the sloc until after the correct adjustment has
5229 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
5230 the adjustment, because it will be outside the range in (the old,
5231 incorrect) S_Adjustment.
5232 * inline.adb: Use named notation for readability and uniformity.
5233 * sinput-l.adb: Minor improvements to debugging output printed

5253 Set_Linker_Section_Pragma to be consistant with the "getter"
5254 Linker_Section_Pragma.
5255 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
5256 checking for container loops so that the index cursor is not
5257 directly changable by the user with the use of E_Loop_Parameter.
5258 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.

5302 * sem_ch12.adb (Analyze_Associations, case of Formal_Package):
5303 Generate a freeze node for the actual of a formal package, if
5304 the actual is declared in the same unit and has a corresponding
5305 body, to prevent the current instance from being frozen before
5308 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>

5330 missing case of controlled generalized indexing.
5331 (Is_Source_Object): Use routine Strip to remove indirections.
5332 (Strip): New routine.
5334 2017-09-06 Bob Duff <duff@adacore.com>
5336 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
5337 we include the proper header. Otherwise, we just declare the necessary
5338 things from the capabilities library. This is so we can build on
5339 machines without that library, while still enabling that library.
5340 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
5341 simply return 0 if the library is not present, or not included

5357 has no parameter specification and no entry index, use the entry name
5358 as the end of the generated SCO statement.
5360 2017-09-06 Steve Baird <baird@adacore.com>
5362 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
5363 uses of 'Image and related attributes as having side effects in
5364 order to avoid replicating such uses.
5365 * pprint.ads (Expression_Image) Add new generic formal flag
5366 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
5367 (eventually) override the default.
5368 * pprint.adb (Expression_Image) If the new flag is set, then
5369 suppress the ".all" suffix when displaying a dereference whose
5370 prefix is a use of a value-capturing compiler temp of the sort
5371 generated by Expr_Util.Remove_Side_Effects .

5387 so that applies to any entity.
5389 2017-09-06 Yannick Moy <moy@adacore.com>
5391 * sem_ch3.adb (Derived_Type_Declaration): Use
5392 Incomplete_Or_Partial_View rather than local Find_Partial_View.

5406 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5408 * exp_ch6.adb (Expand_Call_Helper): Do not optimize calls to

5410 bodies are properly covered.
5412 2017-09-06 Bob Duff <duff@adacore.com>
5414 * sem_ch13.adb (Resolve_Aspect_Expressions): If

5416 directly visible in aspect clauses.
5418 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5420 * sem_res.adb (Resolve_Arithmentic_Op): If both operands are
5421 Universal_Real and the context is a floating-point type, resolve
5422 both operands to the target type.

5429 2017-09-06 Yannick Moy <moy@adacore.com>
5431 * freeze.adb (Check_Inherited_Conditions): Rewriting
5432 of inherited preconditions and postconditions should only occur
5433 in GNATprove mode, that is, when GNATprove_Mode is True, not to
5434 be confused with SPARK_Mode being On.
5436 2017-09-06 Yannick Moy <moy@adacore.com>

5769 discriminant to be used in the retrieval of the value of the
5770 component must be the entity in the type of the right-hand side.

6434 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
6435 Refine predicate for the case where the primitive operation
6436 is a renaming of equality. An overriding operation that is
6437 a user-defined renaming of predefined equality inherits its
6438 slot from the overridden operation. Otherwise it is treated
6439 as a predefined op and occupies the same predefined slot as
6440 equality. A call to it is transformed into a call to its alias,
6441 which is the predefined equality. A dispatching call thus uses
6442 the proper slot if operation is further inherited and called
6443 with class-wide arguments.
6445 2017-05-02 Justin Squirek <squirek@adacore.com>
6447 * errout.adb (Set_Msg_Text): Add a case to switch the message

6480 * exp_ch3.adb (Build_Initialization_Call): Generate a null
6481 statement if the initialization call is a null procedure, as
6482 can happen with a controlled type with no explicit Initialize
6483 procedure, or an array of such.

6485 controlled components that has a trivial Initialize procedure,
6486 insert declaration for finalization counter after object

6489 finalization block and attendant declarations if component has
6490 a trivial Initialize procedure.
6491 (Make_Init_Call): Do not generate a call if controlled type has
6492 a trivial Initialize procedure.
6494 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>

6524 * checks.ads (Null_Exclusion_Static_Checks): Add Boolean
6525 parameter Array_Comp to indicate the case of an array object
6526 with null-excluding components.
6527 * checks.adb (Null_Exclusion_Static_Checks):
6528 Call Compile_Time_Constraint_Error instead of
6529 Apply_Compile_Time_Constraint_Error in the component case. Also
6530 call that when Array_Comp is True, with an appropriate warning for
6531 the array component case. Only create an explicit initialization
6532 by null in the case of an object of a null-excluding access type
6533 (and no longer do that in the component case).
6534 * sem_ch3.adb (Check_Component): Add a Boolean parameter
6535 Array_Comp defaulted to False. Pass Empty for the Comp
6536 actual when calling Null_Exclusion_Static_Checks in the case
6537 where Comp_Decl matches Object_Decl, because we don't have a
6538 component in that case. In the case of an object or component
6539 of an array type, pass True for Array_Comp on the recursive call

6544 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
6545 compute the linux priority from the Ada priority. Call this everywhere
6546 required. In particular, the previous version was not doing this
6547 computation when setting the ceiling priority in various places. It
6548 was just converting to C.int, which results in a ceiling that is off
6551 2017-05-02 Ed Schonberg <schonberg@adacore.com>

6585 visibility rules for equality operators that apply within an
6586 instantiation apply within an inlined body.
6587 * sem_type.adb (Add_One_Interp): ditto.
6589 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>

6617 * opt.ads: Add missing GNAT markers in comments.
6618 * opt.adb (Set_Opt_Config_Switches): Do not override earlier
6619 settings of Optimize_Alignment at the end.
6621 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>
6623 * checks.adb (Apply_Constraint_Check): Do not apply
6624 a discriminant check when the associated type is a constrained
6625 subtype created for an unconstrained nominal type.
6626 * exp_attr.adb: Minor reformatting.
6628 2017-05-02 Bob Duff <duff@adacore.com>

6653 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
6655 2017-05-02 Bob Duff <duff@adacore.com>
6657 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6658 to find primitive ops, instead of using an Identifier that will
6659 later be looked up. This is necessary because these ops are not
6660 necessarily visible at all places where we need to call them.
6661 * exp_util.ads: Minor comment fix.
6663 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6665 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6666 references are fully conformant if they are both expansions
6667 of the discriminant of a protected type, within one of the
6668 protected operations. One occurrence may be expanded into a
6669 constant declaration while the other is an input parameter to
6670 the corresponding generated subprogram.

6700 array components specially.
6702 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6704 * sem_ch8.adb (Premature_Usage): If the premature usage of
6705 an entity is as the expression in its own object decaration,
6706 rewrite the reference as Any_Id to prevent cascaded errors or
6707 compiler loops when such an entity is used in an address clause.
6709 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6711 * gcc-interface/decl.c (components_to_record): Add missing guard.

6716 Put back pending fields onto the regular list if the misalignment
6717 happens to cancel itself.
6719 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6721 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
6722 controlling actual in a prefixed call, preserve the original node
6723 information if the prefix itself has been rewritten, for ASIS use.
6725 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6727 * exp_ch6.adb (Insert_Post_Call_Actions):
6728 Code clean up. Insert the post-call actions after an enclosing
6729 procedure call when N denotes a function call and appears as an
6730 actual parameter in the procedure call.
6732 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6734 * freeze.adb (Check_Component_Storage_Order): If there is a clause
6735 for the component, also reject the attribute if the component
6736 doesn't end on a byte boundary and its scalar storage order is
6737 different from that of the enclosing record type.
6739 2017-04-28 Javier Miranda <miranda@adacore.com>
6741 * atree.ads (Info_Messages): Removed.

6771 2017-04-28 Bob Duff <duff@adacore.com>
6773 * sem_util.ads, sem_util.adb (Might_Raise): New function
6774 that replaces Is_Exception_Safe, but has the opposite
6775 sense. Is_Exception_Safe was missing various cases -- calls inside
6776 a pragma Debug, calls inside an 'if' or assignment statement,
6777 etc. Might_Raise now walks the entire subtree looking for things
6779 * exp_ch9.adb (Is_Exception_Safe): Remove.
6780 (Build_Protected_Subprogram_Body): Replace call to
6781 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
6782 constants where possible).
6783 * exp_ch7.adb: Rename Is_Protected_Body -->

6821 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6822 that follows an expression function must not be relocated to
6823 the generated body, because it applies to the code that follows.
6825 2017-04-28 Gary Dismukes <dismukes@adacore.com>
6827 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
6828 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
6829 code that might violate the more stringent checking for 'Access
6830 introduced in Ada 2005.
6832 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6834 * a-cforse.adb: minor style fix in comment.
6836 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6838 * exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
6839 initialize Block_Decls variable.

6854 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
6855 node between access types, freeze the designated type as well,
6856 so that dispatch table pointers are created in the proper scope,
6857 and not in the constructed body of the expression function.
6859 2017-04-28 Bob Duff <duff@adacore.com>
6861 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6862 value makes large compilations faster, but small compilations slower.
6864 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6866 * sem_util.adb: minor typos in Is_Child_Or_Sibling.

6884 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6886 * sem_res.adb (In_Instance_Code): New predicate in
6887 Valid_Conversion, to determine whether a type conversion appears
6888 as (or within) an actual for a formal object. Type conversions
6889 in instances are not rechecked in Valid_Conversion because
6890 visibility changes between generic location andi instance may
6891 lead to spurious errors, but conversions within an actual must be
6892 fully checked, and they are not fully resolved when pre-analyzing
6895 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6897 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
6898 New_Copy_Tree instead of Relocate_Node as any subsequent copies
6899 of the relocated node will have mangled Parent pointers.
6900 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
6901 tables used in conjunction with entity and itype replication.
6902 (Visit_Entity): Rewrite the restriction on which entities

6957 For efficiency, cache results of Is_Internal_File_Name and
6958 Is_Predefined_File_Name in the Units table. This avoids a lot

6973 (Strict_Equal): Removed, model functions should be used instead.
6974 (No_Overlap): Removed, model functions should be used instead.

6992 * exp_util.adb (Replace_Entity): The prefix of a 'Result
6993 attribute reference in a post- condition is the subprogram to
6994 which the condition applies. If the condition is inherited
6995 by a type extension, the prefix becomes a reference to the
6996 inherited operation, but there is no need to create a wrapper
6997 for this operation, because 'Result is expanded independently
6998 when elaborating the postconditions.

7011 * alloc.ads (Nodes_Initial): Use a much larger value, because
7012 the compiler was spending a lot of time copying the nodes table
7013 when it grows. This number was chosen in 1996, so is rather out
7014 of date with current memory sizes. Anyway, it's virtual memory.
7015 Get rid of Orig_Nodes_...; use Node_... instead.
7016 * atree.adb (Lock): Do not release the Nodes tables; it's a
7018 Orig_Nodes_ ==> Nodes_
7019 * nlists.adb: Orig_Nodes_ ==> Nodes_

7064 of Expand_Dispatching_Call. If the denoted subprogram has a
7065 class-wide precondition, this is the only precondition that
7066 applies to the call, rather that the class-wide preconditions
7067 that may apply to the body that is executed. (This is specified

7078 * sem_prag.adb (Inherit_Class_Wide_Pre): If the parent operation
7079 is itself inherited it does not carry any contract information,
7080 so examine its parent operation which is its Alias.
7082 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7084 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
7085 prefix can be an object reference in which case Obj'Image (X)
7086 can only be interpreted as an indexing of the parameterless
7087 version of the attribute.
7088 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
7089 an indexing or a slice operation if the attribute does not require
7090 parameters. In Ada2012 'Image also belongs in this category,
7091 and A'Image (lo .. hi) is legal and must be parsed as a slice.
7093 2017-04-27 Yannick Moy <moy@adacore.com>
7095 * exp_ch4.adb: Minor reformatting.
7096 * gnat1drv.adb (Adjust_Global_Switches): When in GNATprove mode,

7435 Build body of subprogram that has a class-wide condition that
7436 contains calls to other primitives.
7437 (Build_Class_Wide_Clone_Call); Build a call to the common
7438 class-wide clone of a subprogram with classwide conditions. The
7439 body of the subprogram becomes a wrapper for a call to the
7440 clone. The inherited operation becomes a similar wrapper to which
7441 modified conditions apply, and the call to the clone includes
7442 the proper conversion in a call the parent operation.
7443 (Build_Class_Wide_Clone_Decl (Spec_Id : Entity_Id): For a
7444 subprogram that has a classwide condition that contains calls to
7445 other primitives, build an internal subprogram that is invoked

7455 and rewrite original body as a wrapper as a wrapper for a call to
7456 the clone, so that it incorporates the original pre/postconditions
7458 * freeze.adb (Check_Inherited_Conditions): For an inherited
7459 subprogram that inherits a classwide condition, build spec and
7460 body of corresponding wrapper so that call to inherited operation
7461 gets the modified conditions.
7462 * contracts.adb (Analyze_Contracts): If analysis of classwide

7482 * sem_ch13.adb (Analyze_Attribute_Definition_Clause
7483 [Attribute_Address]): Call Set_Address_Taken when ignoring rep
7484 clauses, so that we keep an indication of the address clause

7508 * sem_ch8.adb (Find_Direct_Name): Account for the case where
7509 a use-visible entity is defined within a nested scope of an

7526 * sem_prag.adb (Analyze_Global_Item):
7527 Do not consider discriminants because they are not "entire
7528 objects". Remove the discriminant-related checks because they are
7530 (Analyze_Input_Output): Do not consider discriminants
7531 because they are not "entire objects".
7533 2017-04-27 Ed Schonberg <schonberg@adacore.com>

7536 perform check if the current scope does not come from source,
7537 as is the case for a rewritten task body, because check has
7538 been performed already, and may not be doable because of changed

7752 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
7753 to manage the secondary stack when an enclosing scope already
7754 performs this functionality (aka relaxed management). Switch
7755 -gnatd.s may be used to force strict management in which case
7756 the block will manage the secondary stack unconditionally. Add
7757 a guard to stop the traversal when encountering a package or a

7762 * sem_res.adb (Resolve_Call): Refine further the handling of
7763 limited views of return types in function calls. If the function
7764 that returns a limited view appears in the current unit,
7765 we do not replace its type by the non-limited view because
7766 this transformation is performed int the back-end. However,
7767 the type of the call itself must be the non-limited view, to
7768 prevent spurious resolution errors.

7775 (Class_Wide_Clone): New attribute of subprogram. Designates
7776 subprogram created for primitive operations with class-wide
7777 pre/postconditions that contain calls to other primitives. The
7778 clone holds the body of the original primitive, but the
7779 pre/postonditions do not apply to it. The original body is
7780 rewritten as a wrapper for a call to the clone.
7781 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7782 the flag is set, no code for the corresponding pre/postconditions
7783 is inserted into its body.

7855 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
7856 point type actual that has user-defined arithmetic primitives,
7857 when there is a previous actual for a formal package that defines
7858 a fixed-point type with the parent user-defined operator.

7874 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
7875 dimensions of operands if node has been analyzed already, because
7876 previous analysis and dimension checking will have removed the
7877 dimension information from the operands.

7881 * debug.adb: Document the use of switch -gnatd.s.

7933 2017-04-25 Arnaud Charlet <charlet@adacore.com>
7935 * exp_ch4.adb (Expand_N_Case_Expression): Emit error message when
7936 generating C code on complex case expressions.
7938 2017-04-25 Arnaud Charlet <charlet@adacore.com>
7940 * sem_prag.adb (Analyze_Pragma): Generate a warning instead
7941 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
7942 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
7943 Ada_2012 instead of Ada_2005 to be compatible with the above

7964 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
7965 * sinput-p.adb: Use regular fat pointers, with bounds checking,
7966 for source buffers. Fix misc obscure bugs.
7967 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
7968 checking, for source buffers. Modify representation clause for
7969 Source_File_Record as appropriate. Move Source_File_Index_Table
7970 from spec to body, because it is not used outside the body.
7971 Move Set_Source_File_Index_Table into the private part, because
7972 it is used only in the body and in children. Use trickery to
7973 modify the dope in the generic instantiation case. It's ugly,
7974 but not as ugly as the previous method. Fix documentation.
7975 Remove obsolete code.

7991 expander is not active or when index/range checks are suppressed
7993 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
7994 Remove variants that include a Supress parameter. These routines
7995 are never used, and were introduced before the current scope-based
7996 check suppression method.

8047 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
8048 the Internal_Source buffer. This removes the incorrect call to "="
8049 the customer noticed.
8050 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
8051 eventually need to eliminate them altogether. Or else get rid
8052 of zero-origin addressing.
8054 2017-04-25 Claire Dross <dross@adacore.com>
8056 * exp_util.ads (Expression_Contains_Primitives_Calls_Of): New
8057 function used in GNATprove to know if an expression contains

8338 an unchecked_union, check whether enclosing scope is a Write
8339 subprogram. Replace attribute with a Raise_Program_Error if the

8427 * sem_res.adb (Resolve_Type_Conversion):
8428 When resolving against any fixed type, set the type of the
8429 operand as universal real when the operand is a multiplication
8430 or a division where both operands are of any fixed type.
8431 (Unique_Fixed_Point_Type): Add local variable ErrN. Improve the
8432 placement of an error message by pointing to the operand of a
8433 type conversion rather than the conversion itself.

8462 2017-04-25 Yannick Moy <moy@adacore.com>
8464 * sem_util.adb, sem_util.ads (Unique_Defining_Entity): Update
8465 comment to reflect which entity is chosen as unique entity.
8466 (Unique_Entity): Return full view instead of private spec for
8467 protected type or task type. Fix possible incorrect access when
8470 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8472 * sem_res.adb (Set_Slice_Subtype): Treat specially bit-packed

8498 overridden operation is itself inherited, it won't have any explicit
8501 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8503 * sem_warn.adb (Warn_On_Overlapping_Actuals): There can be no
8504 overlap if the two formals have different types, because formally
8505 the corresponding actuals cannot designate the same objects.
8507 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8509 * sem_dim.adb (Dimensions_Of_Operand): minot cleanups: a) If
8510 dimensions are present from context, use them. b) If operand is
8511 a static constant rewritten as a literal, obtain the dimensions
8512 from the original declaration, otherwise use dimensions of type

8532 * sem_disp.adb (Check_Dispatching_Context): Add guard to refine
8533 the check that recognizes a call to a private overridding and
8534 replaces the called subprogram with its alias.
8536 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8538 * exp_util.adb: Minor reformatting.
8540 2017-04-25 Justin Squirek <squirek@adacore.com>
8542 * exp_ch3.adb (Freeze_Type): Add condition to always treat
8543 interface types as a partial view of a private type for the
8544 generation of invariant procedure bodies.
8545 * exp_util.adb, exp_util.ads (Add_Inherited_Invariants):
8546 Add a condition to get the Corresponding_Record_Type for
8547 concurrent types, add condition to return in the absence of a
8548 class in the pragma, remove call to Replace_Type_References,
8549 and add call to Replace_References.
8550 (Add_Interface_Invariatns),
8551 (Add_Parent_Invariants): Modify call to Add_Inherited_Invariants
8552 to including the working type T.
8553 (Add_Own_Invariants): Remove
8554 legacy condition for separate units, remove dispatching for ASIS
8555 and save a copy of the expression in the pragma expression.
8556 (Build_Invariant_Procedure_Body): Default initalize vars,
8557 remove return condition on interfaces, always use the
8558 private type for interfaces, and move the processing of types
8559 until after the processing of invariants for the full view.
8560 (Build_Invariant_Procedure_Declaration): Remove condition
8561 to return if an interface type is encountered and add
8562 condition to convert the formal parameter to its class-wide
8563 counterpart if Work_Typ is abstract.

8565 (Replace_Type_Ref): Remove class-wide dispatching for the current
8566 instance of the type.
8567 (Replace_Type_References): Remove parameter "Derived"
8568 (Remove_Controlling_Arguments): Created in order to removing

8585 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
8586 (10-15): if derived type T with progenitors is abstract,
8587 and primitive P of this type inherits non-trivial classwide
8588 preconditions from both a parent operation and from an interface
8589 operation, then the inherited operation is abstract if the parent
8590 operation is not null.
8591 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
8592 with Covered_Interface_Op to yield the actual interface operation
8593 that is implemented by a given inherited operation.

8597 * exp_ch4.adb (Expand_N_Op_Expon): Relocate left
8598 and right operands after performing the validity checks. Required

8603 * exp_attr.adb (Attribute_Unrestricted_Access):
8604 Do not disable implicit type conversion. Required to generate

8616 values, and comparing them must use Expr_Value_S.
8618 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8620 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
8621 dereference is introduced for the object, and the object is
8622 overloaded, do not check whether it is aliased, because it may
8623 include an implicit dereference.
8624 * sem_type.adb (Disambiguate): If two interpretations are access
8625 attribute types with the same designated type keep either of
8626 them and do not report an ambiguity. A true ambiguity will be
8629 2017-04-25 Bob Duff <duff@adacore.com>
8631 * a-numeri.ads: Change the encoding of Greek letter Pi from
8632 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
8633 to indicate the encoding. We considered using a byte order mark
8634 (BOM), but that causes various trouble (misc software eats the
8635 BOM, if you have a patch with a BOM, then it's not at the start
8636 of the patch, so it's not a BOM, the BOM affects with-ing files,

8679 * sem_ch3.adb (Has_Non_Trivial_Precondition): New predicate to
8680 enforce legality rule on classwide preconditions inherited from
8681 both an ancestor and a progenitor (RM 6.1.1 (10-13).
8682 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
8683 subprogram need not be dispatching if it appears in a precondition
8684 for an abstract or null subprogram.
8686 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8688 * sem_ch10.adb: Minor typo fix.

8698 (Is_Predefined_File_Name): Likewise. Adjust comment.
8700 2017-04-25 Bob Duff <duff@adacore.com>
8702 * exp_aggr.adb (Component_Count): Protect the
8703 arithmetic from attempting to convert a value >= 2**31 to Int,
8704 which would otherwise raise Constraint_Error.
8706 2017-04-25 Bob Duff <duff@adacore.com>
8708 * opt.ads (Locking_Policy): Fix incorrect documentation. The
8709 first character of the policy name is not unique.

8732 Save and restore the value of global flag
8733 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value

8735 the corresponding spec or the body must ignore all SPARK_Mode
8736 pragmas found within.
8737 (Analyze_Subprogram_Declaration): Mark
8738 the spec when it needs to ignore all SPARK_Mode pragmas found
8739 within to allow the body to infer this property in case it is
8740 instantiated or inlined later.
8741 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
8742 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
8743 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
8744 when the corresponding spec also ignored all SPARK_Mode pragmas
8746 (Analyze_Package_Declaration): Mark the spec when
8747 it needs to ignore all SPARK_Mode pragmas found within to allow
8748 the body to infer this property in case it is instantiated or
8750 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
8751 Save and restore the value of flag
8752 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
8753 formal spec when it needs to ignore all SPARK_Mode
8754 pragmas found within to allow the body to infer this
8755 property in case it is instantiated or inlined later.
8756 (Analyze_Package_Instantiation): Save and restore the value
8757 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
8758 the instance spec when it needs to ignore all SPARK_Mode

8762 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
8763 instance spec and anonymous package when they need to ignore
8764 all SPARK_Mode pragmas found within to allow the body to infer
8765 this property in case it is instantiated or inlined later.
8766 (Instantiate_Package_Body): Save and restore the value of global
8767 flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set the value of

8778 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
8779 all SPARK_Mode pragmas defined within yields mode "off".
8781 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8783 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.

8800 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8802 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
8803 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
8804 variable and set it to True whenever the main hash table is
8805 populated. Short- circuit the Assoc function if it is false
8806 and add associated guards.
8808 2017-04-25 Olivier Hainque <hainque@adacore.com>
8810 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
8811 specs without elaboration code that have an elaboration counter
8812 nevertheless, e.g. when compiled with -fpreserve-control-flow.
8813 * sem_ch10.adb (Analyze_Compilation_Unit):
8814 Set_Elaboration_Entity_Required when requested to preserve
8815 control flow, to ensure the unit elaboration is materialized at
8816 bind time, resulting in the inclusion of the unit object file
8817 in the executable closure at link time.
8819 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8821 * exp_dbug.adb: In Debug_Renaming_Declaration,
8822 when dealing with indexed component, accept to produce a renaming
8823 symbol when the index is an IN parameter or when it is a name
8824 defined in an outer scope.
8826 2017-04-25 Yannick Moy <moy@adacore.com>
8828 * errout.adb (Error_Msg): Adapt continuation
8829 message in instantiations and inlined bodies for info messages.
8831 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8833 * fname.adb (Has_Internal_Extension): Add pragma Inline.
8834 Use direct 4-character slice comparisons.
8836 pragma Inline. (Has_Suffix): Delete.
8837 (Is_Internal_File_Name):
8838 Test Is_Predefined_File_Name first.
8839 (Is_Predefined_File_Name):
8840 Use direct slice comparisons as much as possible and limit all
8841 comparisons to at most 8 characters.
8843 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8845 * checks.adb (Insert_Valid_Check): Code cleanup.
8846 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8847 (Expand_Actuals): Generate proper copy-back for a validation
8848 variable when it acts as the argument of a type conversion.
8849 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8850 predicate to operate on type qualifications.
8852 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8854 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8857 2017-04-25 Bob Duff <duff@adacore.com>
8859 * sem_prag.adb (No_Return): Give an error if the pragma applies
8860 to a body. Specialize the error for the specless body case,
8861 as is done for (e.g.) pragma Convention.
8862 * debug.adb: Add switch -gnatd.J to disable the above legality
8863 checks. This is mainly for use in our test suite, to avoid
8864 rewriting a lot of illegal (but working) code. It might also
8865 be useful to customers. Under this switch, if a pragma No_Return
8866 applies to a body, and the procedure raises an exception (as it
8867 should), the pragma has no effect. If the procedure does return,
8868 execution is erroneous.
8870 2017-04-25 Bob Duff <duff@adacore.com>
8872 * exp_ch6.adb (Expand_Actuals): This is the
8873 root of the problem. It took N as an 'in out' parameter, and in
8874 some cases, rewrote N, but then set N to Original_Node(N). So
8875 the node returned in N had no Parent. The caller continued
8876 processing of this orphaned node. In some cases that caused a
8877 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8878 and trips over the Empty Parent). The solution is to make N an
8879 'in' parameter. Instead of rewriting it, return the list of
8880 post-call actions, so the caller can do the rewriting later,
8881 after N has been fully processed.
8882 (Expand_Call_Helper): Move most of Expand_Call here. It has
8883 too many premature 'return' statements, and we want to do the
8884 rewriting on return.
8885 (Insert_Post_Call_Actions): New procedure to insert the post-call
8886 actions in the appropriate place. In the problematic case,
8887 that involves rewriting N as an Expression_With_Actions.
8888 (Expand_Call): Call the new procedures Expand_Call_Helper and
8889 Insert_Post_Call_Actions.
8891 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8893 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
8894 properly type derived from generic formal types, to handle
8895 properly modified version of ACATS 4.1B B611017.
8897 2017-04-25 Javier Miranda <miranda@adacore.com>
8899 * exp_unst.adb (Subp_Index): Adding missing
8900 support for renamings and functions that return a constrained
8901 array type (i.e. functions for which the frontend built a
8902 procedure with an extra out parameter).
8904 2017-04-25 Pascal Obry <obry@adacore.com>
8906 * s-string.adb: Minor code clean-up.
8908 2017-04-25 Bob Duff <duff@adacore.com>
8910 * s-os_lib.ads, s-os_lib.adb (Non_Blocking_Wait_Process): New
8912 * adaint.h, adaint.c (__gnat_portable_no_block_wait): C support
8913 function for Non_Blocking_Wait_Process.
8915 2017-04-25 Bob Duff <duff@adacore.com>
8917 * prep.adb (Preprocess): Remove incorrect
8918 Assert. Current character can be ASCII.CR.
8920 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8922 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
8923 convention Stdcall, which has a number of exceptions. Convention
8924 is legal on a component declaration whose type is an anonymous
8925 access to subprogram.
8927 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8929 * sem_ch4.adb: sem_ch4.adb Various reformattings.

8957 to pragma Assert, because older compilers do not support that.
8959 2017-04-25 Bob Duff <duff@adacore.com>
8961 * s-fileio.adb (Close): When a temp file is
8962 closed, delete it and clean up its Temp_File_Record immediately,
8963 rather than waiting until later.
8964 (Temp_File_Record): Add File
8965 component, so Close can know which Temp_File_Record corresponds
8966 to the file being closed.
8967 (Delete): Don't delete temp files,
8968 because they are deleted by Close.
8969 (Open): Set the File component
8970 of Temp_File_Record. This requires moving the creation of the
8971 Temp_File_Record to the end, after the AFCB has been created.
8973 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8975 * checks.adb (Insert_Valid_Check): Do not generate

9000 conversions from float to integer in GNATprove mode.
9001 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
9002 to call Apply_Type_Conversion_Checks, so that range checks
9003 are properly positioned when needed on conversions, including
9004 when converting from float to integer. (Determine_Range): In
9005 GNATprove mode, take into account the possibility of conversion
9006 from float to integer.
9007 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
9008 check on conversions from fixed-point to integer, not anymore
9009 on conversions from floating-point to integer, when in GNATprove

9031 * exp_attr.adb (Make_Range_Test): Add processing for validation
9032 variables to avoid extra reads and copies of the prefix.

9034 variables in order to reflect any changes done in the variable
9035 back into the original object.
9036 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
9037 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

9048 Analyze_Pre_Post_Condition, to implement the legality checks
9049 mandated by AI12-0131: Pre'Class shall not be specified for an
9050 overriding primitive subprogram of a tagged type T unless the
9051 Pre'Class aspect is specified for the corresponding primitive
9052 subprogram of some ancestor of T.
9054 2017-04-25 Bob Duff <duff@adacore.com>
9056 * sem_ch8.adb (Use_One_Type): If a use_type_clause
9057 is redundant, set its Used_Operations to empty. This is only
9058 necessary for use clauses that appear in the parent of a generic
9059 child unit, because those use clauses get reanalyzed when we
9060 instantiate the generic, and we don't want the Used_Operations
9061 carried over from the original context (where it was probably

9077 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9079 * sem_ch8.adb (Find_Type): For an attribute reference
9080 'Class, if prefix type is synchronized and previous errors
9081 have suppressed the creation of the corresponding record type,
9082 create a spurious class-wide for the synchonized type itself,
9083 to catch other misuses of the attribute

9091 if CodePeer_Mode is True, then don't generate the
9092 tag checks for the result of call to an instance of
9093 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
9094 descendant of" check and the accessibility check).
9096 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9098 * sem_ch13.adb: Code cleanups.
9099 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

9105 (Expand_Concatenate): When optimization is enabled, also expand
9106 the operation out-of-line if the concatenation is present within
9107 the expression of the declaration of a library-level object and
9108 not only if it is the expression of the declaration.
9110 2017-04-25 Bob Duff <duff@adacore.com>
9112 * freeze.adb (Freeze_Object_Declaration): Do
9113 not Remove_Side_Effects if there is a pragma Linker_Section,
9114 because in that case we want static initialization in the
9115 appropriate section.
9117 2017-04-25 Gary Dismukes <dismukes@adacore.com>
9119 * exp_dbug.adb: Minor rewording and reformatting.
9121 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9123 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
9124 handle the proposed changes to rules concerning potentially
9125 unevaluated expressions, to include selected components that
9126 do not depend on discriminants, and indexed components with
9128 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
9129 predicate in quantified expression, and fix bugs in the handling
9130 of case expressions and membership test.
9131 (Analyze_Attribute_Old_Result): use new predicate.

9142 * namet.ads, namet.adb (Global_Name_Buffer): Increase the length

9148 renaming entity for debug information, mark the entity as needing debug
9149 info if it comes from sources.
9151 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9153 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
9154 restriction converning the use of 'Address where the prefix is
9155 of a controlled type.

9172 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
9173 internal calls that appear in preconditions of protected
9174 operations, in default values for same, and in contract guards
9175 for contract cases in SPARK.

9186 * a-numaux-x86.ads: Fix package description.
9187 * a-numaux-x86.adb (Is_Nan): Minor tweak.
9188 (Reduce): Adjust and complete description. Call Is_Nan instead of
9189 testing manually. Use an integer temporary to hold rounded value.
9190 * a-numaux-darwin.adb (Reduce): Likewise.
9191 (Is_Nan): New function.
9193 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9195 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
9196 on analysis of prefix whose type is a current instance of a
9197 synchronized type, but where the prefix itself is an entity that
9200 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9202 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
9203 the identity of callable entities therein, because they have been
9204 properly resolved, and prefixed calls may have been rewritten
9207 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
9209 * exp_ch3.adb (Build_Init_Statements): Convert
9210 the expression of the pragma/aspect Secondary_Stack_Size to

9213 corresponding record.
9215 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
9217 * sem_eval.adb (Compile_Time_Compare): Reinstate the expr+literal
9218 (etc) optimizations when the type is modular and the offsets

9223 * s-osinte-freebsd.ads: Minor comment tweaks
9225 2017-04-25 Javier Miranda <miranda@adacore.com>
9227 * urealp.adb (UR_Write): Reverse previous patch
9228 adding documentation on why we generate multiplications instead
9229 of divisions (needed to avoid expressions whose computation with
9230 large numbers may cause division by 0).
9232 2017-04-25 Bob Duff <duff@adacore.com>
9234 * erroutc.adb (Set_Specific_Warning_Off,
9235 Set_Warnings_Mode_Off): Use the correct source file for
9236 Stop. Was using Current_Source_File, which is only valid during
9237 parsing. Current_Source_File will have a leftover value from
9238 whatever file happened to be parsed last, because of a with_clause
9241 2017-04-25 Bob Duff <duff@adacore.com>
9243 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
9244 to In_Predefined_Unit, but including GNAT units.
9245 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
9246 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
9247 because Should_Ignore_Pragma was not working reliably outside
9248 the parser, because Current_Source_File is not valid.
9249 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
9250 * par-prag.adb: Call Should_Ignore_Pragma_Par.
9252 2017-04-25 Arnaud Charlet <charlet@adacore.com trojanek>

9287 Build_Invariant_Procedure_Body.
9288 (Build_Invariant_Procedure_Body):
9289 Remove refactored calls and integrated code from
9290 Add_Parent_Invariants and Add_Interface_Invariants.

9317 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9319 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
9320 of prefix whose type is a current instance of a synchronized
9321 type. If the prefix is an object this is an external call (or
9322 requeue) that can only access public operations of the object. The
9323 previous predicate was too restrictive, and did not allow public
9324 protected operations, only task entries.
9326 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9328 * sem_ch5.adb, fname.adb: Minor reformatting.
9330 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

9333 * einfo.ads Update the placement of
9334 E_Anonymous_Access_Subprogram_Type along with all subtypes that

9337 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
9338 master for an access type subject to pragma No_Heap_Finalization.
9339 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
9340 allocated or deallocated does not finalization actions if the
9341 associated access type is subject to pragma No_Heap_Finalization.
9342 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
9343 * par-prag.adb Pragma No_Heap_Finalization does not need special
9344 processing from the parser.
9345 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
9346 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
9347 * sem_prag.adb Add an entry in table Sig_Flags for pragma
9348 No_Heap_Finalization.
9349 (Analyze_Pragma): Add processing for

9353 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
9354 and corresponding pragma id.
9356 2017-04-25 Bob Duff <duff@adacore.com>
9358 * freeze.adb (Freeze_Record_Type): Use the
9359 underlying type of the component type to determine whether it's
9360 elementary. For representation clause purposes, a private type
9361 should behave the same as its full type.
9362 * fname.ads, fname.adb (Is_Predefined_File_Name):
9363 Make sure things like "system.ali" are recognized as predefined.
9365 2017-04-25 Javier Miranda <miranda@adacore.com>
9367 * debug.adb: Update documentation of -gnatd.6.
9369 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9371 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
9372 element iterator when the name is an overloaded function call,
9373 one of whose interpretations yields an array.
9375 2017-04-25 Bob Duff <duff@adacore.com>
9377 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
9378 Is_Internal_Unit_Name): New functions for operating on unit
9379 names, as opposed to file names. There's some duplicated code
9380 with fname.adb, which is unfortunate, but it seems like we don't
9381 want to add dependencies here.
9382 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
9383 to Is_Predefined_Unit_Name; the former was wrong, because Uname
9384 is not a file name at all.
9385 * fname.ads, fname.adb: Document the fact that
9386 Is_Predefined_File_Name and Is_Internal_File_Name can be called
9387 for ALI files, and fix the code so it works properly for ALI
9388 files. E.g. these should return True for "system.ali".
9390 2017-04-25 Justin Squirek <squirek@adacore.com>
9392 * exp_util.adb (Add_Invariant): Removed,
9393 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
9394 and Add_Own_Invariant. (Add_Invariant_Check): Used
9395 for adding runtime checks from any kind of invariant.
9396 (Add_Inherited_Invariant): Generates invariant checks for
9397 class-wide invariants (Add_Interface_Invariants): Removed, code
9398 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
9399 Create a types own invariant procedure (Add_Parent_Invariants):
9400 Removed, code moved to Build_Invariant_Procedure_Body
9401 (Build_Invariant_Procedure_Body): Add refactored calls
9402 and integrated code from Add_Parent_Invariants and
9403 Add_Interface_Invariants.
9404 (Process_Type): Removed, the
9405 relavant code was inlined into both Add_Own_Invariant and
9406 Add_Inherited_Invariant.
9408 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9410 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

9427 and Build_Invariant_Procedure_Declaration.
9428 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
9429 and Build_Invariant_Procedure_Declaration from exp_ch7
9430 and break-out Is_Untagged_Private_Derivation from
9431 Build_Invariant_Procedure_Body.
9432 (Replace_Type_References):
9433 Append an extra parameter to allow for dispatching replacements
9434 and add the corrasponding logic.
9435 (Type_Invariant): Remove
9436 Replace_Typ_Refs and replace its references with calls to
9437 Replace_Type_References.

10320 * exp_spark.adb (Expand_SPARK_Attribute_Reference): For
10321 attributes which return Universal_Integer, introduce a conversion
10322 to the expected type with the appropriate check flags set.
10323 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
10324 base type if the range is null. It may still be invalid if it
10325 is higher than the lower bound. This is checked later in the
10326 context in which the range appears.

10341 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
10342 an object declaration for an array type with a modular index type
10343 with the size of Long_Long_Integer. Special processing is needed
10344 in this case to compute reliably the size of the object, and
10345 eventually to raise Storage_Error, when wrap-around arithmetic
10346 might compute a meangingless size for the object.

10355 * sem_res.adb (Resolve_Call): In the part of the code where
10356 it is deciding whether to turn the call into an indexed
10357 component, avoid doing so if the call is to an instance of
10358 Unchecked_Conversion. Otherwise, the compiler turns it into an
10359 indexed component, and resolution of that turns it back into a
10360 function call, and so on, resulting in infinite recursion.
10361 * sem_util.adb (Needs_One_Actual): If the first formal has a
10362 default, then return False.

10407 2017-01-20 Ed Schonberg <schonberg@adacore.com>
10409 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
10410 must be treated as delayed aspect even if the expression is
10411 a literal, because the aspect affects the freezing and the
10412 elaboration of the object to which it applies.
10414 2017-01-20 Tristan Gingold <gingold@adacore.com>
10416 * s-osinte-vxworks.ads (Interrup_Range): New subtype.

10913 * sem_dim.adb (Analyze_Dimension): Analyze object declaration and
10914 identifier nodes that do not come from source, to handle properly
10915 dimensionality check within an inlined body which inclddes both
10916 original operands and rewritten operands. This removes spurious
10917 dimensionality errors in the presence of front-end inlining,
10918 as well as in SPARK mode.
10920 2017-01-16 Jakub Jelinek <jakub@redhat.com>

10959 * scil_ll.adb: Minor style fix in comment.
10960 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
10961 even if entity is already set, because the node may be renalyzed
10962 after inlining transformations.
10964 2017-01-13 Javier Miranda <miranda@adacore.com>
10966 * sem_res.adb (Resolve_Call): Do not establish a transient scope
10967 for a call to inlinable expression function (since the call will
10968 be replaced by its returned object).

10991 * sem_ch6.adb (Cloned_Expression): New subprogram.
10992 (Freeze_Expr_Types): Complete previous patch since the expression
10993 of an expression-function may have iterators and loops with
10994 defining identifiers which, as part of the preanalysis of the
10995 expression, may be left decorated with itypes that will not be
10996 available in the tree passed to the backend.

11013 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11015 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
11016 Ensure that the input body is a subprogram body before trying to
11017 determine whether it denoted an expression function. Note that
11018 subprogram body stubs cannot denote expression functions.
11020 2017-01-13 Gary Dismukes <dismukes@adacore.com>

11036 2017-01-13 Bob Duff <duff@adacore.com>
11038 * binde.adb (Elab_New): New elaboration order algorithm
11039 that is expected to cause fewer ABE issues. This is a work in
11040 progress. The new algorithm is currently disabled, and can be
11041 enable by the -dp switch, or by modifying the Do_Old and Do_New
11042 etc. flags and rebuilding. Experimental code is included to
11043 compare the results of the old and new algorithms.
11044 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
11045 can have multiple of these tables, so the old and new algorithms
11047 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
11048 parameter of type array. This avoids the global variable, and
11049 allows bounds checking (which is normally defeated by the tables
11050 packages). It also ensures that the Elab_Order is read-only
11052 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
11053 subprograms that need it, as above.
11054 * debug.adb: Document new -dp switch. Modify doc of old -do
11056 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
11057 and Bindgen. Move writing of closure (-R and -Ra switches)
11058 to Binde; that's more convenient.
11060 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11062 * sem_ch6.adb (Analyze_Expression_Function): If the expression
11063 function is a completion, all entities referenced in the
11064 expression are frozen. As a consequence, a reference to an
11065 uncompleted private type from an enclosing scope is illegal.
11067 2017-01-13 Javier Miranda <miranda@adacore.com>
11069 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
11070 (Analyze_Subprogram_Body_Helper): At the occurrence of an
11071 expression function declaration that is a completion, its
11072 expression causes freezing (AI12-0103).
11074 2017-01-13 Vadim Godunko <godunko@adacore.com>
11076 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

11086 initialize an object when it is of a task type and restriction
11087 No_Tasking is in effect because the initialization is obsolete.
11088 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
11089 restriction No_Tasking is in effect.
11090 (Build_Master_Renaming): Do not rename a master when restriction
11091 No_Tasking is in effect.

11096 the legality of An others clause applies as well to a choice in
11097 an Iterated_component_ association.
11098 (Resolve_Iterated_Component_Association): An others choice
11100 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
11101 Iterated_Component_Association is not static.
11103 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11105 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
11106 control is passed to the expresion handler before the new mode

11125 from sem_aggr.adb, for use elsewhere.
11126 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
11127 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
11128 Iterated_Component_Present.
11129 * exp_aggr.adb: Use Choice_List throughout, to handle
11130 Iterated_Component_Associations.
11131 (Gen_Loop): Generate proper loop for an
11132 Iterated_Component_Association: loop variable has the identifier
11133 of the original association. Generate a loop even for a single
11134 component choice, in order to make loop parameter visible in
11136 (Flatten): An Iterated_Component_Association is not static.
11138 2017-01-13 Yannick Moy <moy@adacore.com>
11140 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
11141 float exponentiation for statically known small negative values
11142 is the reciprocal of the exponentiation for the opposite value
11144 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
11145 Ensure that the value of float exponentiation for negative values
11146 is the reciprocal of the exponentiation for the opposite value
11148 * inline.adb (Expand_Inlined_Call): Fix the count
11149 for the number of generated gotos.
11151 2017-01-13 Yannick Moy <moy@adacore.com>

11155 expression in delay statement as OK for volatile context.
11157 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11159 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
11160 mode a choice that is a subtype with a static predicate is
11161 replaced by the values it covers. This transformation must not
11162 be performed in ASIS mode, to preserve the source for analysis.
11164 2017-01-13 Justin Squirek <squirek@adacore.com>
11166 * nlists.ads: Correct minor typo.
11168 2017-01-13 Gary Dismukes <dismukes@adacore.com>

11175 Iterated_Component_Association is a named association in an
11177 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
11178 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
11179 and resolve the discrete choices and the expression of the
11181 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
11182 Loop_Actions and Box_Present are attributes of
11183 N_Iterated_Component_Association nodes. Box_Present is always
11184 False in this case.
11185 * sprint.adb (Sprint_Node): An Iterated_Component_Association
11186 has a Discrete_Choices list, as specified in the RM. A
11187 Component_Association for aggregate uses instead a Choices list.
11188 We have to live with this small inconsistency because the new
11189 construct also has a defining identifier, and there is no way
11190 to merge the two node structures.
11192 2017-01-13 Yannick Moy <moy@adacore.com>
11194 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the

11201 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
11202 Analyze_Declarations, to analyze and resolve the expressions of
11203 aspect specifications in the current declarative list, so that
11204 the expressions have proper entity and type info. This is needed
11205 for ASIS when there is no subsequent expansion to generate this
11206 semantic information.
11207 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
11208 original expression, to suppress cascaded errors when expression
11209 has been constant-folded.
11210 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
11211 ASIS mode, because there is no subsequent expansion to decorate
11214 2017-01-13 Yannick Moy <moy@adacore.com>
11216 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
11217 New function to detect when a call may be inlined or not in
11219 (Expand_Inlined_Call): Ensure that a temporary
11220 is always created in the cases where a type conversion may be
11221 needed on an input parameter in GNATprove mode, so that GNATprove
11222 sees the check to perform.
11223 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
11224 when not applicable due to actual requiring type conversion
11225 with possible check but no temporary value can be copied for
11226 GNATprove to see the check.
