1 2017-12-15 Ed Schonberg <schonberg@adacore.com>
3 * exp_unst.adb (Unnest_Subprograms): Nothing to do if the main unit is
4 a generic package body. Unnesting is only an issue when generating
5 code, and if the main unit is generic then nested instance bodies have
6 not been created and analyzed, and unnesting will crash in the absence
9 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
11 * inline.adb (Add_Inlined_Body): Do not add a function which is
12 completed by an expression function defined in the same context as the
13 initial declaration because the completing body is not in a package
15 (Is_Non_Loading_Expression_Function): New routine.
17 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
19 * debug.adb: Move the functionality of -gnatdL to -gnatd_i. Restore
20 the behavior of -gnatdL from before revision 255412.
21 * sem_elab.adb: Update the section of compiler switches.
22 (Build_Call_Marker): Do not create a marker for a call which originates
23 from an expanded spec or body of an instantiated gener, does not invoke
24 a generic formal subprogram, the target is external to the instance,
25 and -gnatdL is in effect.
26 (In_External_Context): New routine.
27 (Process_Conditional_ABE_Activation_Impl): Update the uses of -gnatdL
29 (Process_Conditional_ABE_Call): Update the uses of -gnatdL and
31 * switch-c.adb (Scan_Front_End_Switches): Switch -gnatJ now sets switch
33 * exp_unst.adb: Minor typo fixes and edits.
35 2017-12-15 Ed Schonberg <schonberg@adacore.com>
37 * sem_ch6.adb (Possible_Freeze): Do not set Delayed_Freeze on an
38 subprogram instantiation, now that the enclosing wrapper package
39 carries an explicit freeze node. THis prevents freeze nodes for the
40 subprogram for appearing in the wrong scope. This is relevant when the
41 generic subprogram has a private or incomplete formal type and the
42 instance appears within a package that declares the actual type for the
43 instantiation, and that type has itself a delayed freeze.
45 2017-12-15 Patrick Bernardi <bernardi@adacore.com>
47 * doc/gnat_ugn/gnat_and_program_execution.rst: Removed references to
48 the environment variable GNAT_STACK_LIMIT from the Stack Overflow
49 Checking section as it is no longer used by any of our supported
52 2017-12-15 Bob Duff <duff@adacore.com>
54 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
55 Init_Assignment is rewritten, we need to set Assignment_OK on the new
56 node. Otherwise, we will get spurious errors when initializing via
59 2017-12-15 Arnaud Charlet <charlet@adacore.com>
61 * exp_unst.adb (Visit_Node): Refine handling of 'Access to ignore non
63 (Has_Non_Null_Statements): Moved to sem_util for later reuse.
65 2017-12-15 Eric Botcazou <ebotcazou@adacore.com>
67 * exp_attr.adb (Is_Inline_Floating_Point_Attribute): Fix comment.
68 * libgnat/s-fatgen.adb (Model): Use Machine attribute.
69 (Truncation): Likewise.
71 2017-12-15 Bob Duff <duff@adacore.com>
73 * exp_ch7.adb (Expand_Cleanup_Actions): Make sure the block and handled
74 statement sequence generated for certain extended return statements
75 have a Sloc that is not No_Location. Otherwise, the back end doesn't
76 set any location and ends up reading uninitialized variables.
78 2017-12-15 Bob Duff <duff@adacore.com>
80 * types.ads, exp_ch6.adb, libgnat/s-regexp.ads, opt.ads: Partly revert
81 r255414, committed by mistake.
83 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
85 * gcc-interface/Makefile.in: Generalize support for symbolic traces.
87 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
89 * gcc-interface/misc.c (default_pass_by_ref): Minor tweak.
91 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
93 * gcc-interface/trans.c (Call_to_gnu): Set DECL_DISREGARD_INLINE_LIMITS
94 to 0 on the callee if the call is recursive.
96 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
98 * gcc-interface/decl.c (gnat_to_gnu_field): Do not set the alignment
99 of the enclosing record type if it is not already set.
101 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
103 * gcc-interface/gigi.h (pad_type_has_rm_size): Declare.
104 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Do not build
105 a padding type for the alignment before validating the size.
106 Flip conditional construct and add a comment.
107 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Size>: Make sure to
108 apply the exception for padded objects to the type of the object.
109 * gcc-interface/utils.c (hash_pad_type): New static function.
110 (lookup_and_insert_pad_type): Rename into...
111 (canonicalize_pad_type): ...this. Call hash_pad_type, do only one
112 lookup with insertion and always return the canonical type.
113 (maybe_pad_type): Adjust to above changes. Set debug type later.
114 (pad_type_has_rm_size): New predicate.
115 (set_reverse_storage_order_on_pad_type): Adjust to above changes.
117 2017-12-13 Eric Botcazou <ebotcazou@adacore.com>
119 * gcc-interface/trans.c (Subprogram_Body_to_gnu): Initialize locus.
121 2017-12-13 Eric Botcazou <ebotcazou@adacore.com>
123 * gcc-interface/trans.c (process_freeze_entity): Be prepared for a
124 package without body.

128 * gcc-interface/decl.c (gnat_to_gnu_entity): Robustify test for types
129 descendant of System.Address.
130 (gnat_to_gnu_subprog_type): Likewise.
132 2017-12-08 Jakub Jelinek <jakub@redhat.com>
134 * gcc-interface/utils.c (gnat_internal_attribute_table): Add
135 exclusions to the comment.
137 2017-12-07 Martin Sebor <msebor@redhat.com>
140 * gcc-interface/utils.c (gnat_internal_attribute_table): Initialize
141 new member of struct attribute_spec.
143 2017-12-06 Simon Wright <simon@pushface.org>
146 * bindgen.adb (Gen_AdaFinal): If the restriction No_Task_Termination is
147 set, generate a null body.
149 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
151 * sem_util.adb (Contains_Refined_State): Remove.
153 2017-12-05 Ed Schonberg <schonberg@adacore.com>
155 * sem_ch13.adb (Analyze_Aspect_Specifications, case Predicate): A
156 predicate cannot apply to a formal type.
158 2017-12-05 Arnaud Charlet <charlet@adacore.com>
160 * exp_unst.ads: Fix typos.
162 2017-12-05 Jerome Lambourg <lambourg@adacore.com>
164 * libgnarl/s-taprop__qnx.adb: Better detect priority ceiling bug in
165 QNX. At startup, the first mutex created has a non-zero ceiling
166 priority whatever its actual policy. This makes some tests fail
167 (c940013 for example).
169 2017-12-05 Bob Duff <duff@adacore.com>
171 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Call
172 Expand_Cleanup_Actions for N_Extended_Return_Statement.
173 * exp_ch7.adb (Expand_Cleanup_Actions): Handle
174 N_Extended_Return_Statement by transforming the statements into a
175 block, and (indirectly) calling Expand_Cleanup_Actions on the block.
176 It's too hard for Expand_Cleanup_Actions to operate directly on the
177 N_Extended_Return_Statement, because it has a different structure than
178 the other node kinds that Expand_Cleanup_Actions.
179 * exp_util.adb (Requires_Cleanup_Actions): Add support for
180 N_Extended_Return_Statement. Change "when others => return False;" to
181 "when others => raise ...;" so it's clear what nodes this function
182 handles. Use named notation where appropriate.
183 * exp_util.ads: Mark incorrect comment with ???.
185 2017-12-05 Javier Miranda <miranda@adacore.com>
187 * exp_ch9.adb (Install_Private_Data_Declarations): Add missing
188 Debug_Info_Needed decoration of internally generated discriminal
189 renaming declaration.
191 2017-12-05 Arnaud Charlet <charlet@adacore.com>
193 * exp_unst.adb (Unnest_Subprogram): Add handling of 'Access on
196 2017-12-05 Sergey Rybin <rybin@adacore.com>

199 option for gnatmetric, gnatpp, gnat2xml, and gnattest.
201 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
203 * sem_util.adb (Contains_Refined_State): Remove.
205 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
207 * rtsfind.ads: Add new enumeration literals: RE_Clock_Time (for
208 Ada.Real_Time.Clock_Time) and RO_CA_Clock_Time (for
209 Ada.Calendar.Clock_Time).
211 2017-12-05 Ed Schonberg <schonberg@adacore.com>
213 * sem_ch4.adb (Is_Private_Overriding): If the candidate private
214 subprogram is overloaded, scan the list of homonyms in the same
215 scope, to find the inherited operation that may be overridden
217 * exp_ch11.adb, exp_ch7.adb: Minor reformatting.
219 2017-12-05 Bob Duff <duff@adacore.com>
221 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
222 Init_Assignment is rewritten, we need to set Assignment_OK on the new
223 node. Otherwise, we will get spurious errors when initializing via
224 assignment statement.
226 2017-12-05 Hristian Kirtchev <kirtchev@adacore.com>
228 * sem_elab.adb: Update the terminology and switch sections.
229 (Check_SPARK_Model_In_Effect): New routine.
230 (Check_SPARK_Scenario): Verify the model in effect for SPARK.
231 (Process_Conditional_ABE_Call_SPARK): Verify the model in effect for

235 (Process_Conditional_ABE_Variable_Assignment_SPARK): Verify the model
238 2017-12-05 Nicolas Setton <setton@adacore.com>
240 * terminals.c (__gnat_setup_child_communication): As documented,
241 __gnat_setup_child_communication should not terminate - it is intended
242 to be used as the child process of a call to fork(). However, execvp
243 might actually return in some cases, for instance when attempting to
244 run a 32-bit binary on a 64-bit Linux distribution when the
245 compatibility packages are not installed. In these cases, exit the
246 program to conform to the documentation.
248 2017-12-05 Olivier Hainque <hainque@adacore.com>
250 * libgnat/s-tsmona.adb: Fix for oversight in the tsmona interface
253 2017-12-05 Gary Dismukes <dismukes@adacore.com>

261 * sem_util.adb (Set_Convention): Always clear Can_Use_Internal_Rep
262 on access to subprogram types with foreign convention.
264 2017-12-05 Yannick Moy <moy@adacore.com>

267 Guide description of default settings of warnings.
269 2017-12-05 Olivier Hainque <hainque@adacore.com>
271 * s-dwalin.adb (Read_And_Execute_Isn): Adjust test checking for the end
272 of section. Add comments explaining the rationale of the computation.
274 2017-12-05 Bob Duff <duff@adacore.com>

322 phase. Resurrect the previous elaboration model as "legacy elaboration
324 (Build_Call_Marker): This routine does not function when the legacy
325 elaboration model is in effect. Do not consider entry calls and requeue
326 statements when debug flag d_e is in effect. Do not consider calls to
327 subprograms which verify the runtime semantics of certain assertion
328 pragmas when debug flag d_p is in effect.
329 (Build_Variable_Reference_Marker): This routine does not function when
330 the legacy elaboration model is in effect.
331 (Check_Elaboration_Scenarios): This routine does not function when the
332 legacy elaboration model is in effect.
333 (Ensure_Prior_Elaboration): The various flags have now been replaced
334 with a state. Do not generate implicit Elaborate[_All] pragmas when
335 their creation has been suppressed.
336 (Ensure_Prior_Elaboration_Static): The with clause is marked based on
337 the requested pragma, not on the nature of the scenario.
338 (In_External_Context): Removed.
339 (Is_Assertion_Pragma_Target): New routine.
340 (Is_Potential_Scenario): Stop the traversal of a task body when
341 reaching an accept or select statement, and debug switch d_a is in
343 (Kill_Elaboration_Scenario): This routine does not function when the
344 legacy elaboration model is in effect.

349 (Process_Conditional_ABE_Access): The various flags have now been
350 replaced with a state.
351 (Process_Conditional_ABE_Activation_Impl): The various flags have now
352 been replaced with a state. Do not process an activation call which

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

409 Improve doc on required packages for linux 32bits.
411 2017-12-05 Doug Rupp <rupp@adacore.com>
413 * tracebak.c (ppc64-vx7): USE_GCC_UNWINDER for 64bit.
415 2017-12-05 Javier Miranda <miranda@adacore.com>
417 * checks.adb (Generate_Range_Check): Force evaluation of the node in
418 more cases. This patch was written to improve the code generated by
419 the CCG compiler but it is enabled for all targets since double
420 evaluation is always a potential source of inefficiency.
422 2017-12-05 Gary Dismukes <dismukes@adacore.com>
424 * doc/gnat_ugn/gnat_utility_programs.rst: Remove reference to obsolete
427 2017-12-05 Eric Botcazou <ebotcazou@adacore.com>
429 * exp_ch5.adb (Expand_Iterator_Loop_Over_Array): Use the SLOC of the
430 iteration scheme throughout, except for the new loop statement(s).
432 2017-12-05 Ed Schonberg <schonberg@adacore.com>
434 * exp_aggr.adb (Gen_Assign): Do not analyze the expressionn of the
435 assignment if it is part of an Iterated_Component_Association: the
436 analysis needs to take place once the loop structure is analyzed and
437 the loop parameter made visible, because references to it typically
438 appear in the corresponding expression. This is necessary if the
439 expression is an aggregate, because previous pre-analysis of the
440 expression does not handle nested aggregates properly.
442 2017-12-05 Bob Duff <duff@adacore.com>
444 * sem_res.adb (Resolve_Allocator): Avoid coextension processing for an
445 allocator that is the expansion of a build-in-place function call.
447 2017-12-05 Olivier Hainque <hainque@adacore.com>
450 * s-trasym__dwarf.adb (spec of Module_Name.Get): Instead of
451 possibly adjusting the lookup address by a load address, expect
452 a extra argument through which the load address can be conveyed
454 (Multi_Module_Symbolic_Traceback): Adjust accordingly. Pass the
455 retrieved load address to Init_Module.
456 * s-tsmona__linux.adb (Get): Honor the new interface.
457 * s-tsmona__mingw.adb (Get): Likewise.
458 * s-dwalin.ads: Adjust comments to be explicit about which
459 addresses are from module info and which are run-time addresses,
460 offsetted by the module load address.
461 * s-dwalin.adb (Set_Load_Address): Simply set C.Load_Slide.
462 Do not alter the module Low and High (relative) addresses.
463 (Is_Inside): Improve documentation regarding the kinds of addresses
464 at hand and correct the test.
465 (Symbolic_Traceback): Use separate variables with explicit names
466 for the address in traceback (run-time value) and the address to
467 lookup within the shared object (module-relative). Adjust the
468 computation of address passed to Symbolic_Address for symbolization.
470 2017-12-05 Arnaud Charlet <charlet@adacore.com>
472 * opt.ads (Expand_Nonbinary_Modular_Ops): New flag.
473 * exp_ch4.adb (Expand_Nonbinary_Modular_Op): Use
474 Expand_Nonbinary_Modular_Ops instead of Modify_Tree_For_C, so that
475 other back-ends can also benefit from the front-end expansion. Remove
476 test for Modify_Tree_For_C in all callers to better share code.
477 * gnat1drv.adb (Adjust_Global_Switches): Set
478 Expand_Nonbinary_Modular_Ops when generating C code.
480 2017-12-05 Ed Schonberg <schonberg@adacore.com>
482 * exp_ch5.adb (Expand_Formal_Container_Loop): Ensure that the loop
483 parameter becomes invisible after analyzing the loop, which has been
484 rewritten as a while-loop.
486 2017-12-05 Doug Rupp <rupp@adacore.com>
488 * vxaddr2line.adb: Revise and enhance for new ports, remove dead ports,
489 and update for 64bit ports.
491 2017-12-05 Bob Duff <duff@adacore.com>
493 * exp_ch6.adb (Build_In_Place_Formal): Search for the formal by suffix
494 instead of the full name.
495 * sem_ch6.adb (Create_Extra_Formals): Make sure there are extra formals
496 in the case of an instance of a generic.
498 2017-12-05 Arnaud Charlet <charlet@adacore.com>
500 (Adjust_Global_Switches): Create an alias GNAT_Annotate to map to
503 2017-12-05 Sebastian Huber <sebastian.huber@embedded-brains.de>
505 * gcc-interface/Makefile.in (RTEMS): Define EH_MECHANISM.
507 2017-12-04 Sebastian Huber <sebastian.huber@embedded-brains.de>
509 * gcc-interface/Makefile.in (RTEMS): Use s-osprim__rtems.adb.
510 * libgnat/s-osprim__rtems.adb: New file.
511 * libgnarl/s-osinte__rtems.adb (pthread_cond_t): Fix alignment.
512 (pthread_mutexattr_t): Likewise.
513 (pthread_rwlockattr_t): Likewise.
514 (pthread_rwlock_t): Likewise.
515 (time_t): Use 64-bit integer.
517 2017-12-01 Sebastian Huber <sebastian.huber@embedded-brains.de>
519 * libgnarl/s-osinte__rtems.ads (pthread_cond_t): Use correct size and
521 (pthread_mutex_t): Likewise.
522 (pthread_rwlock_t): Likewise.
524 2017-11-28 Jakub Jelinek <jakub@redhat.com>
526 * gcc-interface/trans.c (Case_Statement_to_gnu): Build SWITCH_EXPR
527 using build2 instead of build3.
529 2017-11-23 Eric Botcazou <ebotcazou@adacore.com>
532 * gcc-interface/decl.c (gnat_to_gnu_entity): Do not build a variant
533 type for the implementation type of a packed array.
535 2017-11-23 Mike Stump <mikestump@comcast.net>
536 Eric Botcazou <ebotcazou@adacore.com>

1080 * exp_util.adb (Find_Interface_Tag): Default initialize AI_Tag.
1081 * freeze.adb (Check_Component_Storage_Order): Default initialize
1082 Comp_Byte_Aligned rather than silencing messages with pragma
1083 Warnings(Off), which does not work for CodePeer initialization
1084 messages, and given that here the possible read of an unitialized value
1085 depends on a proper use of parameters by the caller.
1086 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.

1099 uninitialized Obj_Decl.
1100 * sem_ch9.adb (Analyze_Requeue): Default initialize Synch_Type.
1101 (Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
1102 which seem to be left uninitialized and possibly read in some cases.
1103 * sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more
1104 precisely. This requires to exchange the test for exiting in case of
1105 too many positions and the increment to Position, inside the loop.
1106 * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,
1107 which cannot be read uninitialized, but the reasons for that are quite
1109 * sem_intr.adb (Check_Intrinsic_Call): Default initialize Rtyp.
1110 * sem_prag.adb (Collect_Subprogram_Inputs_Outputs): Default initialize
1112 * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
1113 and test for presence of non-null Opnd_Type before testing its scope,
1114 in a test which would read its value uninitialized, and is very rarely
1115 exercized (it depends on the presence of an extension of System).

1119 * set_targ.adb (FailN): Mark procedure with No_Return.

1151 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
1152 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
1153 objects can have those special values. Valid_Name_Id could usefully be
1154 used all over the compiler front end, but that's too much trouble for
1155 now. If we did that, we might want to rename:
1156 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
1157 For parameters of type Valid_Name_Id, remove some redundant tests,
1158 including the ones found by CodePeer. Use Is_Valid_Name instead of
1159 membership test when appropriate.
1160 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
1161 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
1162 "in Error_Name_Or_No_Name".
1163 (Check_Parameterless_Call): Use "not Is_Valid_Name" instead of "in

2528 * exp_ch6.adb: (Make_Build_In_Place_Call_In_Object_Declaration): Take
2529 care of unchecked conversions in addition to regular conversions. This
2530 takes care of a case where a type is derived from a private untagged
2531 type that is completed by a tagged controlled type.
2533 2017-10-09 Ed Schonberg <schonberg@adacore.com>
2535 * exp_disp.adb (Build_Class_Wide_Check, Replace_Formals): When
2536 rewriting a class-wide condition, handle properly the case where the
2537 controlling argument of the operation to which the condition applies is
2538 an access to a tagged type, and the condition includes a dispatching
2539 call with an implicit dereference.

2551 Suppress spurious ambiguity error when two traversals of the homonym
2552 chain (first directly, and then through an examination of relevant
2553 interfaces) retrieve the same operation, when other irrelevant homonyms
2554 of the operatioh are also present.
2556 2017-10-09 Ed Schonberg <schonberg@adacore.com>
2558 * sem_util.adb (Object_Access_Level): If the object is the return
2559 statement of an expression function, return the level of the function.
2560 This is relevant when the object involves an implicit conversion
2561 between access types and the expression function is a completion, which
2562 forces the analysis of the expression before rewriting it as a body, so
2563 that freeze nodes can appear in the proper scope.
2565 2017-10-09 Bob Duff <duff@adacore.com>

2574 Make_DT to compute the offset to the top of components referencing
2575 secondary dispatch tables.

2580 (Make_DT): Create a dummy constant object if we can statically build
2581 secondary dispatch tables.
2582 (Make_Secondary_DT): For statically allocated secondary dispatch tables
2583 use the dummy object to compute the offset-to-top field value by means
2584 of the attribute 'Position.
2586 2017-10-09 Bob Duff <duff@adacore.com>
2588 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking
2589 code so if BIPAlloc is not passed in, it will likely raise
2590 Program_Error instead of cause miscellaneous chaos.
2591 (Is_Build_In_Place_Result_Type): Return False if not Expander_Active,
2592 as for the other Is_B-I-P... functions.
2593 * sem_aggr.adb (Resolve_Extension_Aggregate): For an extension
2594 aggregate whose ancestor part is a build-in-place call returning a
2595 nonlimited type, transform the assignment to the ancestor part to use a
2597 * sem_ch3.adb (Build_Itype_Reference): Handle the case where we're
2598 creating an Itype for a library unit entity.
2599 (Check_Initialization): Avoid spurious error message on
2600 internally-generated call.
2601 * sem_ch5.adb (Analyze_Assignment): Handle the case where the
2602 right-hand side is a build-in-place call. This didn't happen when b-i-p
2603 was only for limited types.
2604 * sem_ch6.adb (Create_Extra_Formals): Remove assumption that b-i-p
2605 implies >= Ada 2005.
2606 * sem_ch7.adb (Scan_Subprogram_Refs): Avoid traversing the same nodes

2634 actual for a formal package is an instantiation of a child unit, create
2635 a freeze node for the instance of the parent if it appears in the same
2636 scope and is not frozen yet.
2638 2017-10-09 Pierre-Marie de Rodat <derodat@adacore.com>
2640 * exp_atag.ads, libgnat/a-tags.adb, libgnat/a-tags.ads: Enhance
2641 in-source documentation for tagged types's Offset_To_Top.
2643 2017-10-09 Bob Duff <duff@adacore.com>
2645 * exp_ch3.adb (Build_Assignment): Parameter name N was somewhat
2646 confusing. Same for N_Loc. Remove assumption that b-i-p implies
2647 limited. This is for the case of a function call that occurs as the
2648 default for a record component.
2649 (Expand_N_Object_Declaration): Deal with the case where expansion has
2650 created an object declaration initialized with something like
2652 * exp_ch3.adb: Minor reformatting.
2654 2017-10-09 Ed Schonberg <schonberg@adacore.com>
2656 * exp_attr.adb (Expand_Attribute_Reference, case 'Valid): The prefix of
2657 the attribute is an object, but it may appear within a conversion. The
2658 object itself must be retrieved when generating the range test that
2659 implements the validity check on a scalar type.
2661 2017-10-05 Eric Botcazou <ebotcazou@adacore.com>
2664 * mingw32.h (_O_U8TEXT, _O_U16TEXT, _O_WTEXT): Delete.

2683 * exp_ch6.adb (Expand_Call_Helper): Replace with code more similar to
2685 (Make_Build_In_Place_Call_In_Object_Declaration): Back out previous
2686 change. Set the Etype in the class-wide case. This fixes a regression

2720 (Is_Build_In_Place_Result_Type): New function to accompany
2721 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
2722 sometimes we just have the type on our hands, not the function. For
2723 now, does the same thing as the old version, so build-in-place is
2724 disabled for nonlimited types, except that you can use -gnatd.9 to
2726 * exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
2727 accompany Is_Build_In_Place_Function and
2728 Is_Build_In_Place_Function_Call, because sometimes we just have the
2729 type on our hands, not the function.
2730 (Make_Build_In_Place_Call_In_...): Handle nonlimited build-in-place
2732 (Make_Build_In_Place_Call_In_Object_Declaration): Remove the
2733 questionable code at the end that was setting the Etype.

2735 determine whether "return (...agg...);" is returning from a
2736 build-in-place function.

2738 Remove assumption that b-i-p implies limited (initialization of
2739 In_Place_Expansion).
2740 (Build_Record_Aggr_Code): AI-287: fix comment; it can't be wrapped in
2741 an unchecked conversion. Add assertions.
2742 (Convert_Aggr_In_Object_Decl): Establish_Transient_Scope -- no need for
2743 secondary stack here, just because the type needs finalization. That

2807 for types in expression if the function is within a generic unit.

2914 tree when the expression is resolved through an ASIS-specific call to

3756 2017-09-08 Yannick Moy <moy@adacore.com>
3758 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
3759 return the entity associated with the call.
3760 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
3761 Replace the internal Get_Function_Id with the new
3762 Sem_Aux.Get_Called_Entity.
3763 (Iterate_Call_Parameters): New
3764 procedure to iterate on formals and actuals at the same time.
3765 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
3766 Set SPARK_Mode from spec when set, for analysis
3767 of instance. Restore after analysis of instance.
3768 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
3769 set, for analysis of body instance. Restored automatically at
3770 the end of the subprogram.

3772 Check_Validity_Of_Parameters to False in GNATprove mode.
3773 * opt.ads (Check_Validity_Of_Parameters): Document switch to
3776 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3778 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
3779 (New_Copy_Tree): ...there. Reset the hash tables only if they
3780 were used in the previous invocation.
3781 * s-htable.adb: Fix typo.
3783 2017-09-08 Bob Duff <duff@adacore.com>
3785 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
3787 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3789 * sem_aggr.adb: minor style fix.
3791 2017-09-08 Bob Duff <duff@adacore.com>
3793 * sprint.adb (Write_Corresponding_Source): Ignore if there is
3794 no current source file.
3795 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
3796 Print something helpful in case N is invalid.
3797 * sprint.ads: Minor comment fix.
3799 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3801 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
3804 2017-09-08 Bob Duff <duff@adacore.com>
3806 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
3807 Ada_2020, along the same lines as the other Ada version pragmas.
3809 2017-09-08 Gary Dismukes <dismukes@adacore.com>
3811 * sem_ch12.adb: Minor typo fixes and reformatting.
3813 2017-09-08 Yannick Moy <moy@adacore.com>
3815 * sem_aggr.adb (Resolve_Record_Aggregate):
3816 Rewrite bounds of aggregate subexpressions which may depend on
3817 discriminants of the enclosing aggregate.
3819 2017-09-08 Yannick Moy <moy@adacore.com>
3821 * sem_ch5.adb: Prevent assertion failure on illegal code.
3823 2017-09-08 Yannick Moy <moy@adacore.com>
3825 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
3826 calling Renamed_Entity on an entity which cannot be a renaming.
3828 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3830 * exp_aggr.adb: Add with & use clause for Urealp.
3831 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
3832 elementary types instead of just discrete types.
3833 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
3834 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
3835 Be prepared for the FP zero value in the memset case. Add small
3838 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3840 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
3843 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3845 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
3846 of New_Copy because the latter leaves the syntactic structure of
3847 the tree inconsistent (a child is accessible through two parents)
3848 and prevents proper replication of itypes by subsequent calls
3850 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
3851 New_Copy because the latter leaves the syntactic structure of the
3852 tree inconsistent (a child is accessible through two parents)
3853 and prevents proper replication of itypes by subsequent calls
3855 * sem_util.adb (In_Subtree): New routine.

3862 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
3863 for aspect Default_Value is a static scalar value, but it does
3864 not freeze the type. Yhis allows for subsequent representation
3865 clauses for the type.
3867 2017-09-08 Javier Miranda <miranda@adacore.com>
3869 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
3870 not add entries into the undefined reference table when we are
3871 compiling with errors ignored.
3873 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3875 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
3876 check if the instance is within an enclosing instance body. The
3877 formal package was legal in the enclosing generic, and is
3878 legal in the enclosing instantiation. This optimisation may be
3879 applicable elsewhere, and it also removes spurious errors that
3880 may arise with on-the-fly processing of instantiations that
3881 contain Inline_Always subprograms.
3883 2017-09-08 Vincent Celier <celier@adacore.com>
3885 * gnatcmd.adb: Disregard empty argument of GNAT driver.
3887 2017-09-08 Justin Squirek <squirek@adacore.com>
3889 * checks.adb (Insert_Valid_Check): Manually decorate
3890 the generated temporary for range valdity checks.
3892 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3894 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
3896 2017-09-08 Justin Squirek <squirek@adacore.com>
3898 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
3899 case to handle underscore flags.
3900 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
3901 new procedure to handle underscores.
3903 2017-09-08 Javier Miranda <miranda@adacore.com>
3905 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
3906 divisions with fixed point results to avoid generating twice
3907 the runtime check on divide by zero.
3908 * checks.adb (Apply_Divide_Checks): Ensure that operands are
3909 not evaluated twice (once for their runtime checks and once for
3910 their regular computation).
3912 2017-09-08 Yannick Moy <moy@adacore.com>
3914 * sem_prag.adb (Analyze_Part_Of): Add missing
3915 return statements after issuing errors. Add detection of
3916 out-of-order item and single concurrent type.

4413 2017-09-08 Bob Duff <duff@adacore.com>
4415 * errout.adb (Delete_Warning): Do not
4416 decrement Warnings_Treated_As_Errors. This is called before
4417 Warnings_Treated_As_Errors has been incremented to account for
4418 this warning. Decrementing it here can lead to negative values
4419 of Warnings_Treated_As_Errors, raising Constraint_Error in
4420 checks-on builds, and causing the compiler to return an error
4421 code in checks-off builds.
4423 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4425 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
4426 entities of named concurrent types as Ref_Id and not of anonymous
4427 concurrent objects (because callers already know when a conversion
4428 is necessary and can easily do it); also, do not expect protected
4429 types or protected objects as Context_Id (because no flow-related
4430 SPARK pragmas are attached there); reflect these changes in a
4431 more precise comment.
4433 2017-09-08 Olivier Hainque <hainque@adacore.com>
4435 * g-altive.ads: Add documentation.
4437 2017-09-08 Bob Duff <duff@adacore.com>
4439 * sem_util.ads, debug.adb: Minor comment fix.
4440 * erroutc.ads: Comment fix.
4442 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4444 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
4445 for compatibility of component types of formal and actual in an
4446 instantiation of a child unit, when the component type of the
4447 formal is itself a formal of an enclosing generic.
4449 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4451 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
4452 sem_prag.adb to make it available for GNATprove; for concurrent
4453 types replace custom scope climbing with Scope_Same_Or_Within; for
4454 single concurrent objects add scope climbing (with Scope_Within),
4455 which was not there (that's the primary semantic change of this
4456 commit); also, when comparing a single concurrent object with
4457 its corresponding concurrent type rely on equality of types,
4458 not of objects (because that's simpler to code).
4459 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
4460 (Analyze_Global_Item): adjust special-casing of references to the
4461 current instance of a concurrent unit in the Global contracts
4462 of task types and single tasks objects; similar for references
4463 in the protected operations and entries of protected types and
4464 single protected objects (in all these cases the current instance
4465 behaves as an implicit parameter and must not be mentioned in
4466 the Global contract).
4468 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4470 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
4471 function calls returning a record within a subprogram call,
4474 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4476 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
4477 name that designates the current instance of a child unit in its
4478 own body and appears as the prefix of a reference to an entity
4479 local to the child unit.
4480 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
4483 2017-09-08 Yannick Moy <moy@adacore.com>

4491 warnings on internal units in configurable run time mode.
4493 2017-09-08 Bob Duff <duff@adacore.com>
4495 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
4496 representation items from interfaces that the derived type
4497 implements, not just from the parent type.
4498 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
4499 this to return an empty list when there are no interfaces.
4500 * einfo.ads, sem_ch13.adb: Minor comment fixes.
4501 * sem_attr.adb: Minor comment fix.

4511 call to Allocate_Any_Controlled when the allocation does not
4512 require any initialization.

4516 * sem_util.adb (Copy_Node_With_Replacement):
4517 Update the Renamed_Object field of a replicated object renaming
4520 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
4522 * exp_ch9.adb (Is_Pure_Barrier): Allow type
4523 conversions and components of objects. Simplified the detection
4524 of the Count attribute by identifying the corresponding run-time
4527 2017-09-08 Yannick Moy <moy@adacore.com>

4530 sem_type.adb, sinfo.ads: Minor reformatting.
4532 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4534 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
4535 of Freeze_Profile, used to inhibit the freezing of the profile
4536 of an expression function declared within a nested package, when
4537 some type in the profile depends on a private type declared in
4538 an enclosing package.
4540 2017-09-08 Bob Duff <duff@adacore.com>
4542 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
4543 the subunit case. It's still OK to set it in the "missing subunits"
4544 case, because that won't cause the obsolete .ali files that cause
4547 2017-09-08 Bob Duff <duff@adacore.com>
4549 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
4550 unclear why this didn't cause a warning.
4551 * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
4552 pragmas. It's unclear why this didn't cause an error.
4554 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4556 * exp_spark.adb (Expand_SPARK_N_Object_Renaming_Declaration):
4558 (Expand_SPARK_Potential_Renaming): Code clean up.
4559 * sem_prag.adb (Analyze_Initialization_Item): Add a guard in case
4560 the item does not have a proper entity.

4579 do not override the normalized position and first bit
4580 if they have already been set. Move fallback code
4581 for the packed case to the case where it belongs.
4582 * sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
4583 Also adjust the normalized position of components.
4584 (Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise.
4586 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4588 * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
4589 the placement of a primitive operation O that renames an operation
4590 R declared in an inner package, and which is thus not a primitive
4591 of the dispatching type of O. In this case O is a new primitive
4592 and does not inherit its dispatch table position from R (which

4597 * sem_dim.adb (Analyze_Dimension_If_Expression,
4598 Analyze_Dimension_Case_Expression): new subprograms to verify
4599 the dimensional correctness of Ada2012 conditional expressions,
4600 and set properly the dimensions of the construct.
4601 * sem_res.adb (Resolve_If_Expression, Resolve_Case_Expression)):

4607 loop on an interface declared as a private extension of another
4608 synchronized interface.
4610 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4612 * sem_ch12.adb (Check_Generic_Parent): New procedure within
4613 Analyze_Associations, to handle actual packages that depend on
4614 previous instances. If a package IAP that is an instantiation is
4615 used as an actual in a subsequent instantiation SI in the same
4616 scope, and IAP has a body, IAP must be frozen before SI. If
4617 the generic parent of IAP is itself declared in a previous
4618 instantiation in the same scope, that instantiation must also
4619 be frozen before SI.
4620 (Install_Body): Prevent double insertion of freeze node for
4623 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>

4632 Linker_Section): If the aspect applies to an object declaration
4633 with explicit initialization, do not delay the freezing of the
4634 object, to prevent access-before-elaboration in the generated
4635 initialization code.
4637 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4639 * a-wtdeio.adb (Put, all versions): Use Long_Long_Integer
4640 (Integer_Value (Item)) when the size of the fixed decimal type
4641 is larger than Integer.
4643 2017-09-07 Eric Botcazou <ebotcazou@adacore.com>
4646 * gcc-interface/decl.c (copy_and_substitute_in_layout): Put the fields
4647 in order of increasing position in more cases.

4675 in the external name of the elaboration flag. Required to fix
4676 the regressions introduced by the initial version of this patch.
4678 2017-09-07 Bob Duff <duff@adacore.com>
4680 * sem_ch6.adb (Analyze_Function_Return): Do not
4681 insert an explicit conversion to force the displacement of the
4682 "this" pointer to reference the secondary dispatch table in the
4683 case where the return statement is returning a raise expression,
4684 as in "return raise ...".
4686 2017-09-07 Arnaud Charlet <charlet@adacore.com>

4708 to handle properly various cases of type conversions where the
4709 target type and/or the expression carry dimension information.

4718 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4720 * exp_attr.adb (Expand_N_Attribute_Reference, case 'Constrained):
4721 If the prefix is a reference to an object, rewrite it as an
4722 explicit dereference, as required by 3.7.2 (2) and as is done
4723 with most other attributes whose prefix is an access value.
4725 2017-09-07 Bob Duff <duff@adacore.com>
4727 * par-ch13.adb: Set the Inside_Depends flag if we are inside a
4728 Refined_Depends aspect.

4774 * exp_disp.adb (Replace_Formals): If thr formal is classwide,
4775 and thus not a controlling argument, preserve its type after
4776 rewriting because it may appear in an nested call with a classwide

4787 clause for a unit U appears in a context that includes a regular
4788 with_clause on U, rewrite the redundant private clause into a null
4789 statement, rather than removing it altogether from the context,
4790 so that ASIS tools can reconstruct the original source.

4794 * sem_ch13.adb (Check_Aspect_At_Freeze_Point): The expression

4844 * exp_ch3.adb (Build_Init_Procedure): Improve the code
4845 generated in the IP routines by means of keeping separate
4846 the initialization of the object components from the
4847 initialization of its dispatch tables. (Init_Secondary_Tags):
4848 Adding new formal (Init_Tags_List) and adjusting calls to
4849 Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;
4850 adjusting also calls to Ada.Tags.Register_Interface_Offset
4851 because the type of one of its formals has been changed.
4852 * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
4853 modified. Instead of receiving a pointer to an object this
4854 routine receives now a primary tag.
4855 (Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
4856 additional formal: the tag of the primary dispatch table.
4857 * exp_disp.ads (Elab_Flag_Needed): New subprogram.

4872 * sem_util.adb (Check_Part_Of_Reference): rename Conc_Typ to Conc_Obj
4873 (because it refers to the anonymous concurrent object, not its type);
4874 fix condition for emitting error message about task/protected type,
4876 2017-09-07 Bob Duff <duff@adacore.com>

4889 * sem_prag.adb (Find_Role): The Global_Seen flag
4890 is now consulted not only for abstract states and variables,
4891 but for all kinds of items.
4892 (Collect_Subprogram_Inputs_Outputs): Do not process formal
4893 generic parameters, because unlike ordinary formal parameters,
4894 generic formals only act as input/ outputs if they are explicitly
4895 mentioned in a Global contract.
4897 2017-09-07 Yannick Moy <moy@adacore.com>
4899 * ghost.adb (Check_Ghost_Context): Do not err on ghost code inside

4929 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4931 * par-ch6.adb (P_Subprogram): Improve error message on null
4932 procedure with misplaced aspect specification, which the parser
4933 first attempts to interpret as a malformed expression function.
4935 2017-09-07 Gary Dismukes <dismukes@adacore.com>
4937 * sem_attr.adb (Analyze_Attribute_Old_Result):

4960 Make_Build_In_Place_Call_In_Anonymous_Context): Do not use the
4961 secondary stack for all functions that return limited tagged
4962 types -- just do it for dispatching calls. Misc cleanup.
4963 * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
4964 remove qualifications and type conversions. Fix various bugs
4965 where only a single level of qualification or conversion was
4966 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
4968 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
4971 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4973 * sem_ch6.adb (setr_Actual_Subtypes): Within a predicate function
4974 do not create actual subtypes that may generate further predicate
4976 * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
4977 of body is a predicate function as well.
4978 (Resolve_Aspect_Expressions, Resolve_Name): For a component
4979 association, only the expression needs resolution, not the name.
4980 (Resolve_Aspect_Expressions, case Predicates): Construct and
4981 analyze the predicate function declaration in the scope of the
4982 type, before making the type and its discriminants visible.
4984 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>
4986 * gcc-interface/decl.c (warn_on_field_placement): Issue the warning
4987 only if the record type itself comes from source.

5018 2017-09-06 Bob Duff <duff@adacore.com>
5020 * sem_ch8.adb: Change Assert to be consistent with
5023 2017-09-06 Bob Duff <duff@adacore.com>
5025 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
5026 requested. Previously, the -do switch meant "run Elab_New and
5027 Elab_Old and use the order chosen by Elab_Old, possibly with
5028 debugging printouts comparing the two orders." Now it means
5029 "do not run Elab_New." This is of use if there are bugs that
5030 cause Elab_New to crash.
5031 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various
5033 * ali.ads (Elab_Position): Change type to Nat, to avoid various

5047 * freeze.adb (Freeze_Record_Type)
5048 <Sized_Component_Total_Round_RM_Size>: New local variable to
5049 accumulate the rounded RM_Size of components. Update it for
5050 every component whose RM_Size is statically known. Add missing
5051 guard to check that bit packing is really required before issuing
5052 the error about packing. Swap condition for clarity's sake.
5053 * sem_prag.adb (Usage_Error): Fix reference to SPARK RM in comment.

5072 project manager sources.
5074 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5076 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
5077 entity of a mutable type and the right-hand side is a conditional
5078 expression, resolve the alternatives of the conditional using
5079 the base type of the target entity, because the alternatives
5080 may have distinct subtypes. This is particularly relevant if
5081 the alternatives are aggregates.
5083 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5085 * checks.adb (Apply_Predicate_Check): If the expression is an
5086 aggregate that is the RHS of an assignment, apply the check to
5087 the LHS after the assignment, rather than to the aggregate. This
5088 is more efficient than creating a temporary for the aggregate,
5089 and prevents back-end crashes when the aggregate includes a
5090 dynamic "others' association.
5092 2017-09-06 Yannick Moy <moy@adacore.com>
5094 * sem_ch12.adb (Analyze_Instance_And_Renamings):

5106 * sem_aux.adb (Is_Generic_Formal): Handle properly formal packages.

5110 2017-09-06 Gary Dismukes <dismukes@adacore.com>
5112 * errout.adb (Error_Msg): Separate the
5113 treatment for warning vs. style messages in inlinings and
5114 instantiations. Prevents blowups on calls to Warn_Insertion for
5115 style messages, which should not be called in that case because
5116 Warning_Msg_Char is not set.
5118 2017-09-06 Justin Squirek <squirek@adacore.com>
5120 * sem_prag.adb (Check_VFA_Conflicts): Created
5121 to group all Volatile_Full_Access checks relating to other
5122 representation pragmas (Mark_Component_Or_Object): Created
5123 to centeralize the flagging of attributes for the record type
5124 component case, a pragma applied individually to a component, and
5126 (Process_Atomic_Independent_Shared_Volatile):

5143 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
5144 that is a proper body corresponding to a stub, we defer the
5145 adjustment of the sloc until after the correct adjustment has
5146 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
5147 the adjustment, because it will be outside the range in (the old,
5148 incorrect) S_Adjustment.
5149 * inline.adb: Use named notation for readability and uniformity.
5150 * sinput-l.adb: Minor improvements to debugging output printed

5170 Set_Linker_Section_Pragma to be consistant with the "getter"
5171 Linker_Section_Pragma.
5172 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
5173 checking for container loops so that the index cursor is not
5174 directly changable by the user with the use of E_Loop_Parameter.
5175 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.

5220 Generate a freeze node for the actual of a formal package, if
5221 the actual is declared in the same unit and has a corresponding
5222 body, to prevent the current instance from being frozen before
5225 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>

5249 (Strip): New routine.
5251 2017-09-06 Bob Duff <duff@adacore.com>
5253 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
5254 we include the proper header. Otherwise, we just declare the necessary
5255 things from the capabilities library. This is so we can build on
5256 machines without that library, while still enabling that library.
5257 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
5258 simply return 0 if the library is not present, or not included

5274 has no parameter specification and no entry index, use the entry name
5275 as the end of the generated SCO statement.
5277 2017-09-06 Steve Baird <baird@adacore.com>
5279 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
5280 uses of 'Image and related attributes as having side effects in
5281 order to avoid replicating such uses.
5282 * pprint.ads (Expression_Image) Add new generic formal flag
5283 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
5284 (eventually) override the default.
5285 * pprint.adb (Expression_Image) If the new flag is set, then
5286 suppress the ".all" suffix when displaying a dereference whose
5287 prefix is a use of a value-capturing compiler temp of the sort
5288 generated by Expr_Util.Remove_Side_Effects .

5306 2017-09-06 Yannick Moy <moy@adacore.com>
5308 * sem_ch3.adb (Derived_Type_Declaration): Use
5309 Incomplete_Or_Partial_View rather than local Find_Partial_View.

5346 2017-09-06 Yannick Moy <moy@adacore.com>
5348 * freeze.adb (Check_Inherited_Conditions): Rewriting
5349 of inherited preconditions and postconditions should only occur
5350 in GNATprove mode, that is, when GNATprove_Mode is True, not to
5351 be confused with SPARK_Mode being On.

5368 (Entity_Table_Size): New constant.
5369 (Entity_Hash): New function.
5370 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
5371 (Is_Subprogram_Ref): Rename into...
5372 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
5373 the table instead of bailing out on them. Scan the value of constants
5374 if it is not known at compile time.
5375 (Contains_Subprograms_Refs): Rename into...
5376 (Scan_Subprogram_Refs): ...this.
5377 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
5378 Is_Public flag on subprograms if they are not actually referenced.
5379 (Hide_Public_Entities): Beef up comment on the algorithm.
5380 Reset the table of subprograms on entry.

5493 that Ada.Command_Line contains modern Ada (the raise expression).
5494 * gnatbind.adb: Avoid dependence on

5634 of the right-hand side has stored constraint, use its values
5635 (except for those that are renamings of parent discriminants)

5637 left-hand side, which are invisible in the righ-hand side and
5638 not retrievable as selected components.
5640 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5642 * sem_util.adb (Needs_One_Formal): The first formal of such a

5679 discriminants, the constraint for the target must obtain the
5680 discriminant values from both the operand and from the stored
5681 constraint for it, given that the constrained discriminants are
5682 not visible in the object.
5683 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
5684 side may be derived from that of the left-hand side (as in the
5685 case of an assignment with a change of representation) so the
5686 discriminant to be used in the retrieval of the value of the
5687 component must be the entity in the type of the right-hand side.

5716 in a set membership is an overloaded enumeration literal, and
5717 the type of the alternative is resolved from a previous one,

6262 * exp_ch6.adb (Expand_Call_Helper): When locating the
6263 accessibility entity created for an access parameter, handle
6264 properly a reference to a formal of an enclosing subprogram. if
6265 the reference appears in an inherited class-wide condition, it
6266 is the rewriting of the reference in the ancestor expression,
6267 but the accessibility entity must be that of the current formal.
6269 2017-05-02 Javier Miranda <miranda@adacore.com>
6271 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

6306 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
6307 procedure body for a local (sub)type declaration within a
6308 predicate function. Invariant checks do not apply to these, and
6309 the expansion of the procedure will happen in the wrong scope,
6310 leading to misplaced freeze nodes.
6312 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6314 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
6315 to analyze generated actions. If the main unit is a body,

6351 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
6352 Refine predicate for the case where the primitive operation
6353 is a renaming of equality. An overriding operation that is
6354 a user-defined renaming of predefined equality inherits its
6355 slot from the overridden operation. Otherwise it is treated
6356 as a predefined op and occupies the same predefined slot as
6357 equality. A call to it is transformed into a call to its alias,
6358 which is the predefined equality. A dispatching call thus uses
6359 the proper slot if operation is further inherited and called
6360 with class-wide arguments.
6362 2017-05-02 Justin Squirek <squirek@adacore.com>
6364 * errout.adb (Set_Msg_Text): Add a case to switch the message

6373 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6375 * sem_prag.adb (Process_Conversion): Reject an intrinsic operator
6376 declaration that operates on some fixed point type.

6395 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6397 * exp_ch3.adb (Build_Initialization_Call): Generate a null
6398 statement if the initialization call is a null procedure, as
6399 can happen with a controlled type with no explicit Initialize
6400 procedure, or an array of such.
6401 * exp_ch7.adb (Process_Object_Declaration): For a type with
6402 controlled components that has a trivial Initialize procedure,
6403 insert declaration for finalization counter after object

6406 finalization block and attendant declarations if component has
6407 a trivial Initialize procedure.

6409 a trivial Initialize procedure.

6442 parameter Array_Comp to indicate the case of an array object
6443 with null-excluding components.
6444 * checks.adb (Null_Exclusion_Static_Checks):
6445 Call Compile_Time_Constraint_Error instead of
6446 Apply_Compile_Time_Constraint_Error in the component case. Also
6447 call that when Array_Comp is True, with an appropriate warning for
6448 the array component case. Only create an explicit initialization
6449 by null in the case of an object of a null-excluding access type
6450 (and no longer do that in the component case).
6451 * sem_ch3.adb (Check_Component): Add a Boolean parameter
6452 Array_Comp defaulted to False. Pass Empty for the Comp
6453 actual when calling Null_Exclusion_Static_Checks in the case
6454 where Comp_Decl matches Object_Decl, because we don't have a
6455 component in that case. In the case of an object or component
6456 of an array type, pass True for Array_Comp on the recursive call
6459 2017-05-02 Bob Duff <duff@adacore.com>
6461 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
6462 compute the linux priority from the Ada priority. Call this everywhere
6463 required. In particular, the previous version was not doing this
6464 computation when setting the ceiling priority in various places. It
6465 was just converting to C.int, which results in a ceiling that is off

6502 visibility rules for equality operators that apply within an
6503 instantiation apply within an inlined body.
6504 * sem_type.adb (Add_One_Interp): ditto.

6541 a discriminant check when the associated type is a constrained
6542 subtype created for an unconstrained nominal type.
6543 * exp_attr.adb: Minor reformatting.
6545 2017-05-02 Bob Duff <duff@adacore.com>

6570 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
6572 2017-05-02 Bob Duff <duff@adacore.com>
6574 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6575 to find primitive ops, instead of using an Identifier that will
6576 later be looked up. This is necessary because these ops are not
6577 necessarily visible at all places where we need to call them.
6578 * exp_util.ads: Minor comment fix.
6580 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6582 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6583 references are fully conformant if they are both expansions
6584 of the discriminant of a protected type, within one of the
6585 protected operations. One occurrence may be expanded into a
6586 constant declaration while the other is an input parameter to
6587 the corresponding generated subprogram.

6617 array components specially.
6619 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6621 * sem_ch8.adb (Premature_Usage): If the premature usage of
6622 an entity is as the expression in its own object decaration,
6623 rewrite the reference as Any_Id to prevent cascaded errors or
6624 compiler loops when such an entity is used in an address clause.
6626 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6628 * gcc-interface/decl.c (components_to_record): Add missing guard.

6633 Put back pending fields onto the regular list if the misalignment
6634 happens to cancel itself.
6636 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6638 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
6639 controlling actual in a prefixed call, preserve the original node
6640 information if the prefix itself has been rewritten, for ASIS use.

6644 * exp_ch6.adb (Insert_Post_Call_Actions):
6645 Code clean up. Insert the post-call actions after an enclosing
6646 procedure call when N denotes a function call and appears as an
6647 actual parameter in the procedure call.
6649 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6651 * freeze.adb (Check_Component_Storage_Order): If there is a clause
6652 for the component, also reject the attribute if the component
6653 doesn't end on a byte boundary and its scalar storage order is
6654 different from that of the enclosing record type.
6656 2017-04-28 Javier Miranda <miranda@adacore.com>
6658 * atree.ads (Info_Messages): Removed.

6690 * sem_util.ads, sem_util.adb (Might_Raise): New function
6691 that replaces Is_Exception_Safe, but has the opposite
6692 sense. Is_Exception_Safe was missing various cases -- calls inside
6693 a pragma Debug, calls inside an 'if' or assignment statement,
6694 etc. Might_Raise now walks the entire subtree looking for things
6696 * exp_ch9.adb (Is_Exception_Safe): Remove.
6697 (Build_Protected_Subprogram_Body): Replace call to
6698 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
6699 constants where possible).
6700 * exp_ch7.adb: Rename Is_Protected_Body -->
6701 Is_Protected_Subp_Body. A protected_body is something different

6730 * sem_ch13.adb (Analyze_Aspect_Specifications, case
6731 Interrupt_Handler and Attach_Handler): Generate reference
6732 to protected operation to prevent spurious warnings about

6736 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6738 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6739 that follows an expression function must not be relocated to
6740 the generated body, because it applies to the code that follows.
6742 2017-04-28 Gary Dismukes <dismukes@adacore.com>
6744 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
6745 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
6746 code that might violate the more stringent checking for 'Access
6747 introduced in Ada 2005.
6749 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6751 * a-cforse.adb: minor style fix in comment.
6753 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>

6776 2017-04-28 Bob Duff <duff@adacore.com>
6778 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6779 value makes large compilations faster, but small compilations slower.

6801 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6803 * sem_res.adb (In_Instance_Code): New predicate in
6804 Valid_Conversion, to determine whether a type conversion appears
6805 as (or within) an actual for a formal object. Type conversions
6806 in instances are not rechecked in Valid_Conversion because
6807 visibility changes between generic location andi instance may
6808 lead to spurious errors, but conversions within an actual must be
6809 fully checked, and they are not fully resolved when pre-analyzing
6812 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6814 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
6815 New_Copy_Tree instead of Relocate_Node as any subsequent copies
6816 of the relocated node will have mangled Parent pointers.
6817 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
6818 tables used in conjunction with entity and itype replication.
6819 (Visit_Entity): Rewrite the restriction on which entities

6862 parameters. Rename local variables and adjust recursive call.
6863 Rework final scan of the field list and implement warnings on the
6864 problematic placement of specific sorts of fields.

6874 For efficiency, cache results of Is_Internal_File_Name and
6875 Is_Predefined_File_Name in the Units table. This avoids a lot
6876 of repeated text processing.
6878 2017-04-27 Emmanuel Briot <briot@adacore.com>

6910 attribute reference in a post- condition is the subprogram to
6911 which the condition applies. If the condition is inherited
6912 by a type extension, the prefix becomes a reference to the
6913 inherited operation, but there is no need to create a wrapper
6914 for this operation, because 'Result is expanded independently
6915 when elaborating the postconditions.

6927 Remove unused function.
6928 * alloc.ads (Nodes_Initial): Use a much larger value, because
6929 the compiler was spending a lot of time copying the nodes table
6930 when it grows. This number was chosen in 1996, so is rather out
6931 of date with current memory sizes. Anyway, it's virtual memory.
6932 Get rid of Orig_Nodes_...; use Node_... instead.
6933 * atree.adb (Lock): Do not release the Nodes tables; it's a
6935 Orig_Nodes_ ==> Nodes_

6981 of Expand_Dispatching_Call. If the denoted subprogram has a
6982 class-wide precondition, this is the only precondition that
6983 applies to the call, rather that the class-wide preconditions
6984 that may apply to the body that is executed. (This is specified

7001 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
7002 prefix can be an object reference in which case Obj'Image (X)
7003 can only be interpreted as an indexing of the parameterless
7004 version of the attribute.
7005 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
7006 an indexing or a slice operation if the attribute does not require
7007 parameters. In Ada2012 'Image also belongs in this category,
7008 and A'Image (lo .. hi) is legal and must be parsed as a slice.

7417 Process_Component_List_For_Finalization as a local variable.
7418 (Process_Component_For_Finalize): Add an extra parameter to avoid
7420 (Process_Component_List_For_Finalization): Correct calls to
7421 Process_Component_For_Finalize to take Num_Comps as a parameter.
7423 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7425 * sem_ch8.adb (Find_Direct_Name): Account for the case where
7426 a use-visible entity is defined within a nested scope of an

7453 perform check if the current scope does not come from source,
7454 as is the case for a rewritten task body, because check has
7455 been performed already, and may not be doable because of changed

7511 modifications in functional containers.
7512 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
7513 to improve readablity. Subprograms are separated between basic
7514 operations, constructors and properties. Universally quantified
7515 formulas in contracts are factorized in independant functions
7516 with a name and a comment. Names of parameters are improved.
7518 2017-04-27 Gary Dismukes <dismukes@adacore.com>

7526 the expansion phase. Verify whether the operand satisfies the
7527 static predicate (if any) of the target type.

7529 not install a predicate check if the object is initialized by
7530 means of a type conversion because the conversion is subjected

7606 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
7607 the loop which detects potential enclosing transient scopes. The
7608 loop now terminates much earlier as transient scopes are bounded
7609 by packages and subprograms.
7611 2017-04-27 Claire Dross <dross@adacore.com>
7613 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to

7656 * adaint.c (__gnat_get_current_dir): Return 0 in length if
7658 * a-direct.adb, g-dirope.adb, osint.adb, s-os_lib.adb: Raise
7659 exception if getcwd failed.

7668 * debug.adb Change the documentation of switch -gnatd.s.
7669 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
7670 to manage the secondary stack when an enclosing scope already
7671 performs this functionality (aka relaxed management). Switch
7672 -gnatd.s may be used to force strict management in which case
7673 the block will manage the secondary stack unconditionally. Add
7674 a guard to stop the traversal when encountering a package or a
7677 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7679 * sem_res.adb (Resolve_Call): Refine further the handling of
7680 limited views of return types in function calls. If the function
7681 that returns a limited view appears in the current unit,
7682 we do not replace its type by the non-limited view because
7683 this transformation is performed int the back-end. However,
7684 the type of the call itself must be the non-limited view, to
7685 prevent spurious resolution errors.
7687 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7689 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
7690 Removed, proposed implementation using generics for class-wide
7691 preconditions proved impractical.
7692 (Class_Wide_Clone): New attribute of subprogram. Designates
7693 subprogram created for primitive operations with class-wide
7694 pre/postconditions that contain calls to other primitives. The
7695 clone holds the body of the original primitive, but the
7696 pre/postonditions do not apply to it. The original body is
7697 rewritten as a wrapper for a call to the clone.
7698 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7699 the flag is set, no code for the corresponding pre/postconditions
7700 is inserted into its body.
7702 2017-04-27 Bob Duff <duff@adacore.com>
7704 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore

7748 private child of Ada.Containers used to implement all functional
7750 * a-cofuma.ads, a-cofuma.adb (Ada.Containers.Functional_Maps): New
7751 child of Ada.Containers. It provides functional indefinite unbounded
7752 maps which can be used as high level models for specification
7754 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
7755 child of Ada.Containers. It provides functional indefinite unbounded
7756 sets which can be used as high level models for specification
7758 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
7759 child of Ada.Containers. It provides functional indefinite unbounded
7760 vectors which can be used as high level models for specification

7769 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7771 * sem_ch12.adb (Analyze_Associations): minor reformatting.
7772 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
7773 point type actual that has user-defined arithmetic primitives,
7774 when there is a previous actual for a formal package that defines
7775 a fixed-point type with the parent user-defined operator.
7777 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7779 * checks.adb (Generate_Range_Check): Reinstate part of previous change.
7780 * sem_attr.adb (Resolve_Attribute): Generate a range check when
7781 the component type allows range checks.
7783 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7785 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
7786 corresponding declaration, because formal derived types are
7787 rewritten as private extensions.
7789 2017-04-27 Ed Schonberg <schonberg@adacore.com>
7791 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
7792 dimensions of operands if node has been analyzed already, because
7793 previous analysis and dimension checking will have removed the
7794 dimension information from the operands.
7796 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
7798 * debug.adb: Document the use of switch -gnatd.s.
7799 * einfo.ads Update the documentation on attribute
7800 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
7801 the uses of these attributes from certain entities.

7803 which determines whether the block should continue to manage
7804 the secondary stack.

7853 generating C code on complex case expressions.
7855 2017-04-25 Arnaud Charlet <charlet@adacore.com>
7857 * sem_prag.adb (Analyze_Pragma): Generate a warning instead
7858 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
7859 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
7860 Ada_2012 instead of Ada_2005 to be compatible with the above
7862 * bindgen.adb: Silence new warning on pragma Ada_95.
7864 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

7881 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
7882 * sinput-p.adb: Use regular fat pointers, with bounds checking,
7883 for source buffers. Fix misc obscure bugs.
7884 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
7885 checking, for source buffers. Modify representation clause for
7886 Source_File_Record as appropriate. Move Source_File_Index_Table
7887 from spec to body, because it is not used outside the body.
7888 Move Set_Source_File_Index_Table into the private part, because
7889 it is used only in the body and in children. Use trickery to
7890 modify the dope in the generic instantiation case. It's ugly,
7891 but not as ugly as the previous method. Fix documentation.
7892 Remove obsolete code.

7908 expander is not active or when index/range checks are suppressed
7910 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
7911 Remove variants that include a Supress parameter. These routines
7912 are never used, and were introduced before the current scope-based

8426 * sem_dim.adb (Dimensions_Of_Operand): minot cleanups: a) If
8427 dimensions are present from context, use them. b) If operand is
8428 a static constant rewritten as a literal, obtain the dimensions
8429 from the original declaration, otherwise use dimensions of type
8430 established from context.
8432 2017-04-25 Yannick Moy <moy@adacore.com>
8434 * sem_util.adb (Is_Effectively_Volatile): Protect against base type

8442 2017-04-25 Yannick Moy <moy@adacore.com>
8444 * a-ngelfu.adb, a-ngelfu.ads: Add SPARK_Mode On on spec, Off
8447 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8449 * sem_disp.adb (Check_Dispatching_Context): Add guard to refine
8450 the check that recognizes a call to a private overridding and
8451 replaces the called subprogram with its alias.
8453 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8455 * exp_util.adb: Minor reformatting.
8457 2017-04-25 Justin Squirek <squirek@adacore.com>
8459 * exp_ch3.adb (Freeze_Type): Add condition to always treat
8460 interface types as a partial view of a private type for the
8461 generation of invariant procedure bodies.
8462 * exp_util.adb, exp_util.ads (Add_Inherited_Invariants):
8463 Add a condition to get the Corresponding_Record_Type for
8464 concurrent types, add condition to return in the absence of a
8465 class in the pragma, remove call to Replace_Type_References,
8466 and add call to Replace_References.
8467 (Add_Interface_Invariatns),
8468 (Add_Parent_Invariants): Modify call to Add_Inherited_Invariants
8469 to including the working type T.
8470 (Add_Own_Invariants): Remove
8471 legacy condition for separate units, remove dispatching for ASIS
8472 and save a copy of the expression in the pragma expression.
8473 (Build_Invariant_Procedure_Body): Default initalize vars,
8474 remove return condition on interfaces, always use the
8475 private type for interfaces, and move the processing of types
8476 until after the processing of invariants for the full view.
8477 (Build_Invariant_Procedure_Declaration): Remove condition
8478 to return if an interface type is encountered and add
8479 condition to convert the formal parameter to its class-wide
8480 counterpart if Work_Typ is abstract.

8482 (Replace_Type_Ref): Remove class-wide dispatching for the current
8483 instance of the type.
8484 (Replace_Type_References): Remove parameter "Derived"
8485 (Remove_Controlling_Arguments): Created in order to removing
8486 the controlliong argument from calls to primitives in the case
8487 of the formal parameter being an class-wide abstract type.
8488 * sem_ch3.adb (Build_Assertion_Bodies_For_Type): Almost identical
8489 to the change made to Freeze_Type in exp_ch3. Add a condition
8490 to treat interface types as a partial view.
8491 * sem_prag.adb (Analyze_Pragma): Modify parameters in the call
8492 to Build_Invariant_Procedure_Declaration to properly generate a
8493 "partial" invariant procedure when Typ is an interface.

8497 * a-numeri.ads: Go back to using brackets encoding for the Greek
8500 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8502 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
8503 (10-15): if derived type T with progenitors is abstract,
8504 and primitive P of this type inherits non-trivial classwide
8505 preconditions from both a parent operation and from an interface
8506 operation, then the inherited operation is abstract if the parent
8507 operation is not null.
8508 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
8509 with Covered_Interface_Op to yield the actual interface operation
8510 that is implemented by a given inherited operation.
8512 2017-04-25 Javier Miranda <miranda@adacore.com>
8514 * exp_ch4.adb (Expand_N_Op_Expon): Relocate left
8515 and right operands after performing the validity checks. Required
8516 because validity checks may remove side effects from the operands.
8518 2017-04-25 Javier Miranda <miranda@adacore.com>
8520 * exp_attr.adb (Attribute_Unrestricted_Access):
8521 Do not disable implicit type conversion. Required to generate
8522 code that displaces the pointer to reference the secondary

8533 values, and comparing them must use Expr_Value_S.
8535 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8537 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
8538 dereference is introduced for the object, and the object is
8539 overloaded, do not check whether it is aliased, because it may
8540 include an implicit dereference.
8541 * sem_type.adb (Disambiguate): If two interpretations are access
8542 attribute types with the same designated type keep either of
8543 them and do not report an ambiguity. A true ambiguity will be
8546 2017-04-25 Bob Duff <duff@adacore.com>
8548 * a-numeri.ads: Change the encoding of Greek letter Pi from
8549 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
8550 to indicate the encoding. We considered using a byte order mark
8551 (BOM), but that causes various trouble (misc software eats the
8552 BOM, if you have a patch with a BOM, then it's not at the start
8553 of the patch, so it's not a BOM, the BOM affects with-ing files,
8555 * scng.adb, s-wchcnv.adb: Minor.

8591 restrictions when the handler is internally generated and the
8594 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8596 * sem_ch3.adb (Has_Non_Trivial_Precondition): New predicate to
8597 enforce legality rule on classwide preconditions inherited from
8598 both an ancestor and a progenitor (RM 6.1.1 (10-13).
8599 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
8600 subprogram need not be dispatching if it appears in a precondition
8601 for an abstract or null subprogram.
8603 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8605 * sem_ch10.adb: Minor typo fix.

8614 have a length which is a power of 2.
8615 (Is_Predefined_File_Name): Likewise. Adjust comment.
8617 2017-04-25 Bob Duff <duff@adacore.com>
8619 * exp_aggr.adb (Component_Count): Protect the
8620 arithmetic from attempting to convert a value >= 2**31 to Int,
8621 which would otherwise raise Constraint_Error.
8623 2017-04-25 Bob Duff <duff@adacore.com>
8625 * opt.ads (Locking_Policy): Fix incorrect documentation. The
8626 first character of the policy name is not unique.
8628 2017-04-25 Bob Duff <duff@adacore.com>
8630 * s-fileio.adb (Name): Raise Use_Error if the file is a temp file.
8631 * s-ficobl.ads (Is_Temporary_File): Remove incorrect comment

8649 Save and restore the value of global flag
8650 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value
8651 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance when either
8652 the corresponding spec or the body must ignore all SPARK_Mode
8653 pragmas found within.
8654 (Analyze_Subprogram_Declaration): Mark
8655 the spec when it needs to ignore all SPARK_Mode pragmas found
8656 within to allow the body to infer this property in case it is
8657 instantiated or inlined later.
8658 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
8659 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
8660 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
8661 when the corresponding spec also ignored all SPARK_Mode pragmas
8663 (Analyze_Package_Declaration): Mark the spec when
8664 it needs to ignore all SPARK_Mode pragmas found within to allow
8665 the body to infer this property in case it is instantiated or
8667 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
8668 Save and restore the value of flag
8669 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
8670 formal spec when it needs to ignore all SPARK_Mode
8671 pragmas found within to allow the body to infer this
8672 property in case it is instantiated or inlined later.
8673 (Analyze_Package_Instantiation): Save and restore the value
8674 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
8675 the instance spec when it needs to ignore all SPARK_Mode

8679 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
8680 instance spec and anonymous package when they need to ignore
8681 all SPARK_Mode pragmas found within to allow the body to infer

8683 (Instantiate_Package_Body): Save and restore the value of global
8684 flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set the value of

8694 Ignore_Pragma_SPARK_Mode.
8695 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
8696 all SPARK_Mode pragmas defined within yields mode "off".
8698 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8700 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.

8717 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8719 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
8720 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
8721 variable and set it to True whenever the main hash table is
8722 populated. Short- circuit the Assoc function if it is false
8723 and add associated guards.
8725 2017-04-25 Olivier Hainque <hainque@adacore.com>
8727 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
8728 specs without elaboration code that have an elaboration counter
8729 nevertheless, e.g. when compiled with -fpreserve-control-flow.
8730 * sem_ch10.adb (Analyze_Compilation_Unit):
8731 Set_Elaboration_Entity_Required when requested to preserve
8732 control flow, to ensure the unit elaboration is materialized at
8733 bind time, resulting in the inclusion of the unit object file
8734 in the executable closure at link time.
8736 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8738 * exp_dbug.adb: In Debug_Renaming_Declaration,
8739 when dealing with indexed component, accept to produce a renaming
8740 symbol when the index is an IN parameter or when it is a name
8741 defined in an outer scope.
8743 2017-04-25 Yannick Moy <moy@adacore.com>
8745 * errout.adb (Error_Msg): Adapt continuation
8746 message in instantiations and inlined bodies for info messages.
8748 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8750 * fname.adb (Has_Internal_Extension): Add pragma Inline.
8751 Use direct 4-character slice comparisons.
8753 pragma Inline. (Has_Suffix): Delete.
8754 (Is_Internal_File_Name):
8755 Test Is_Predefined_File_Name first.
8756 (Is_Predefined_File_Name):

8758 comparisons to at most 8 characters.
8760 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8762 * checks.adb (Insert_Valid_Check): Code cleanup.
8763 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8764 (Expand_Actuals): Generate proper copy-back for a validation
8765 variable when it acts as the argument of a type conversion.
8766 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8767 predicate to operate on type qualifications.
8769 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8771 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8774 2017-04-25 Bob Duff <duff@adacore.com>
8776 * sem_prag.adb (No_Return): Give an error if the pragma applies
8777 to a body. Specialize the error for the specless body case,
8778 as is done for (e.g.) pragma Convention.
8779 * debug.adb: Add switch -gnatd.J to disable the above legality
8780 checks. This is mainly for use in our test suite, to avoid
8781 rewriting a lot of illegal (but working) code. It might also
8782 be useful to customers. Under this switch, if a pragma No_Return
8783 applies to a body, and the procedure raises an exception (as it
8784 should), the pragma has no effect. If the procedure does return,
8785 execution is erroneous.
8787 2017-04-25 Bob Duff <duff@adacore.com>
8789 * exp_ch6.adb (Expand_Actuals): This is the
8790 root of the problem. It took N as an 'in out' parameter, and in
8791 some cases, rewrote N, but then set N to Original_Node(N). So
8792 the node returned in N had no Parent. The caller continued
8793 processing of this orphaned node. In some cases that caused a
8794 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8795 and trips over the Empty Parent). The solution is to make N an
8796 'in' parameter. Instead of rewriting it, return the list of
8797 post-call actions, so the caller can do the rewriting later,
8798 after N has been fully processed.
8799 (Expand_Call_Helper): Move most of Expand_Call here. It has
8800 too many premature 'return' statements, and we want to do the
8801 rewriting on return.
8802 (Insert_Post_Call_Actions): New procedure to insert the post-call
8803 actions in the appropriate place. In the problematic case,
8804 that involves rewriting N as an Expression_With_Actions.
8805 (Expand_Call): Call the new procedures Expand_Call_Helper and
8806 Insert_Post_Call_Actions.
8808 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8810 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
8811 properly type derived from generic formal types, to handle
8812 properly modified version of ACATS 4.1B B611017.
8814 2017-04-25 Javier Miranda <miranda@adacore.com>
8816 * exp_unst.adb (Subp_Index): Adding missing
8817 support for renamings and functions that return a constrained
8818 array type (i.e. functions for which the frontend built a
8819 procedure with an extra out parameter).
8821 2017-04-25 Pascal Obry <obry@adacore.com>
8823 * s-string.adb: Minor code clean-up.
8825 2017-04-25 Bob Duff <duff@adacore.com>

8830 function for Non_Blocking_Wait_Process.
8832 2017-04-25 Bob Duff <duff@adacore.com>
8834 * prep.adb (Preprocess): Remove incorrect
8835 Assert. Current character can be ASCII.CR.
8837 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8839 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
8840 convention Stdcall, which has a number of exceptions. Convention
8841 is legal on a component declaration whose type is an anonymous
8842 access to subprogram.
8844 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8846 * sem_ch4.adb: sem_ch4.adb Various reformattings.
8847 (Try_One_Prefix_Interpretation): Use the base type when dealing
8848 with a subtype created for purposes of constraining a private
8849 type with discriminants.
8851 2017-04-25 Javier Miranda <miranda@adacore.com>
8853 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.
8854 * warnsw.ads, warnsw.adb (All_Warnings): Set warning on late
8855 dispatching primitives (Restore_Warnings): Restore warning on
8856 late dispatching primitives (Save_Warnings): Save warning on late
8857 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
8858 to enable/disable this warning.
8859 (WA_Warnings): Set warning on late dispatching primitives.
8860 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
8861 that its parent type has a private extension.
8862 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
8864 * usage.adb: Document -gnatw.j and -gnatw.J.
8866 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8868 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
8871 2017-04-25 Bob Duff <duff@adacore.com>
8873 * binde.adb (Validate): Do not pass dynamic strings
8874 to pragma Assert, because older compilers do not support that.
8876 2017-04-25 Bob Duff <duff@adacore.com>
8878 * s-fileio.adb (Close): When a temp file is
8879 closed, delete it and clean up its Temp_File_Record immediately,
8880 rather than waiting until later.
8881 (Temp_File_Record): Add File
8882 component, so Close can know which Temp_File_Record corresponds
8883 to the file being closed.
8884 (Delete): Don't delete temp files,
8885 because they are deleted by Close.
8886 (Open): Set the File component
8887 of Temp_File_Record. This requires moving the creation of the
8888 Temp_File_Record to the end, after the AFCB has been created.
8890 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8892 * checks.adb (Insert_Valid_Check): Do not generate
8893 a validity check when inside a generic.

8897 * sem_res.adb (Resolve_Type_Conversion): Fix bad logic.
8899 2017-04-25 Arnaud Charlet <charlet@adacore.com>

8902 potentially blocking subprograms.
8904 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8906 * sem_prag.adb (Analyze_Pre_Post_Condition): The rules
8907 concerning inheritance of class-wide preconditions do not apply
8910 2017-04-25 Bob Duff <duff@adacore.com>
8912 * s-ficobl.ads: Minor comment fix.
8914 2017-04-25 Yannick Moy <moy@adacore.com>
8916 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
8917 conversions from float to integer in GNATprove mode.
8918 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
8919 to call Apply_Type_Conversion_Checks, so that range checks
8920 are properly positioned when needed on conversions, including
8921 when converting from float to integer. (Determine_Range): In
8922 GNATprove mode, take into account the possibility of conversion
8923 from float to integer.
8924 * sem_res.adb (Resolve_Type_Conversion): Only enforce range

8932 from integer to float in order to get bounds in that case too.
8933 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
8934 mode, for computations involved in interval checking.

8948 * exp_attr.adb (Make_Range_Test): Add processing for validation
8949 variables to avoid extra reads and copies of the prefix.
8950 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
8951 variables in order to reflect any changes done in the variable
8952 back into the original object.
8953 * sem_util.adb (Is_Validation_Variable_Reference): New routine.

8968 Pre'Class aspect is specified for the corresponding primitive
8969 subprogram of some ancestor of T.
8971 2017-04-25 Bob Duff <duff@adacore.com>
8973 * sem_ch8.adb (Use_One_Type): If a use_type_clause
8974 is redundant, set its Used_Operations to empty. This is only
8975 necessary for use clauses that appear in the parent of a generic
8976 child unit, because those use clauses get reanalyzed when we
8977 instantiate the generic, and we don't want the Used_Operations
8978 carried over from the original context (where it was probably

8994 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8996 * sem_ch8.adb (Find_Type): For an attribute reference
8997 'Class, if prefix type is synchronized and previous errors
8998 have suppressed the creation of the corresponding record type,
8999 create a spurious class-wide for the synchonized type itself,
9000 to catch other misuses of the attribute
9002 2017-04-25 Steve Baird <baird@adacore.com>

9009 tag checks for the result of call to an instance of
9010 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
9011 descendant of" check and the accessibility check).

9022 (Expand_Concatenate): When optimization is enabled, also expand
9023 the operation out-of-line if the concatenation is present within
9024 the expression of the declaration of a library-level object and
9025 not only if it is the expression of the declaration.
9027 2017-04-25 Bob Duff <duff@adacore.com>
9029 * freeze.adb (Freeze_Object_Declaration): Do
9030 not Remove_Side_Effects if there is a pragma Linker_Section,
9031 because in that case we want static initialization in the
9032 appropriate section.
9034 2017-04-25 Gary Dismukes <dismukes@adacore.com>
9036 * exp_dbug.adb: Minor rewording and reformatting.
9038 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9040 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
9041 handle the proposed changes to rules concerning potentially
9042 unevaluated expressions, to include selected components that
9043 do not depend on discriminants, and indexed components with
9045 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
9046 predicate in quantified expression, and fix bugs in the handling
9047 of case expressions and membership test.
9048 (Analyze_Attribute_Old_Result): use new predicate.

9065 renaming entity for debug information, mark the entity as needing debug
9066 info if it comes from sources.
9068 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9070 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the

9103 * a-numaux-x86.ads: Fix package description.
9104 * a-numaux-x86.adb (Is_Nan): Minor tweak.
9105 (Reduce): Adjust and complete description. Call Is_Nan instead of
9106 testing manually. Use an integer temporary to hold rounded value.
9107 * a-numaux-darwin.adb (Reduce): Likewise.
9108 (Is_Nan): New function.
9110 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9112 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
9113 on analysis of prefix whose type is a current instance of a
9114 synchronized type, but where the prefix itself is an entity that
9117 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9119 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
9120 the identity of callable entities therein, because they have been
9121 properly resolved, and prefixed calls may have been rewritten

9126 * exp_ch3.adb (Build_Init_Statements): Convert
9127 the expression of the pragma/aspect Secondary_Stack_Size to

9140 * s-osinte-freebsd.ads: Minor comment tweaks
9142 2017-04-25 Javier Miranda <miranda@adacore.com>
9144 * urealp.adb (UR_Write): Reverse previous patch
9145 adding documentation on why we generate multiplications instead
9146 of divisions (needed to avoid expressions whose computation with
9147 large numbers may cause division by 0).
9149 2017-04-25 Bob Duff <duff@adacore.com>
9151 * erroutc.adb (Set_Specific_Warning_Off,
9152 Set_Warnings_Mode_Off): Use the correct source file for
9153 Stop. Was using Current_Source_File, which is only valid during
9154 parsing. Current_Source_File will have a leftover value from
9155 whatever file happened to be parsed last, because of a with_clause
9158 2017-04-25 Bob Duff <duff@adacore.com>
9160 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
9161 to In_Predefined_Unit, but including GNAT units.
9162 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
9163 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
9164 because Should_Ignore_Pragma was not working reliably outside
9165 the parser, because Current_Source_File is not valid.
9166 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
9167 * par-prag.adb: Call Should_Ignore_Pragma_Par.

9206 Remove refactored calls and integrated code from
9207 Add_Parent_Invariants and Add_Interface_Invariants.
9209 2017-04-25 Johannes Kanig <kanig@adacore.com>
9211 * errout.adb (Output_Messages): Adjust computation of total
9213 * erroutc.adb (Error_Msg): In statistics counts, deal
9214 correctly with informational messages that are not warnings.

9231 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
9234 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9236 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
9237 of prefix whose type is a current instance of a synchronized
9238 type. If the prefix is an object this is an external call (or
9239 requeue) that can only access public operations of the object. The
9240 previous predicate was too restrictive, and did not allow public
9241 protected operations, only task entries.
9243 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9245 * sem_ch5.adb, fname.adb: Minor reformatting.
9247 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9249 * einfo.adb (Is_Anonymous_Access_Type): New routine.
9250 * einfo.ads Update the placement of
9251 E_Anonymous_Access_Subprogram_Type along with all subtypes that
9253 (Is_Anonymous_Access_Type): New routine.
9254 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
9255 master for an access type subject to pragma No_Heap_Finalization.
9256 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
9257 allocated or deallocated does not finalization actions if the
9258 associated access type is subject to pragma No_Heap_Finalization.
9259 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
9260 * par-prag.adb Pragma No_Heap_Finalization does not need special
9261 processing from the parser.
9262 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
9263 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
9264 * sem_prag.adb Add an entry in table Sig_Flags for pragma
9265 No_Heap_Finalization.
9266 (Analyze_Pragma): Add processing for
9267 pragma No_Heap_Finalization. Update various error messages to
9268 use Duplication_Error.
9269 * sem_util.ads, sem_util.adb (No_Heap_Finalization): New routine.
9270 * snames.ads-tmpl: Add new predefined name No_Heap_Finalization
9271 and corresponding pragma id.
9273 2017-04-25 Bob Duff <duff@adacore.com>
9275 * freeze.adb (Freeze_Record_Type): Use the
9276 underlying type of the component type to determine whether it's
9277 elementary. For representation clause purposes, a private type
9278 should behave the same as its full type.
9279 * fname.ads, fname.adb (Is_Predefined_File_Name):
9280 Make sure things like "system.ali" are recognized as predefined.
9282 2017-04-25 Javier Miranda <miranda@adacore.com>
9284 * debug.adb: Update documentation of -gnatd.6.

9288 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
9289 element iterator when the name is an overloaded function call,
9290 one of whose interpretations yields an array.
9292 2017-04-25 Bob Duff <duff@adacore.com>
9294 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
9295 Is_Internal_Unit_Name): New functions for operating on unit
9296 names, as opposed to file names. There's some duplicated code
9297 with fname.adb, which is unfortunate, but it seems like we don't
9298 want to add dependencies here.
9299 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
9300 to Is_Predefined_Unit_Name; the former was wrong, because Uname
9301 is not a file name at all.
9302 * fname.ads, fname.adb: Document the fact that
9303 Is_Predefined_File_Name and Is_Internal_File_Name can be called
9304 for ALI files, and fix the code so it works properly for ALI
9305 files. E.g. these should return True for "system.ali".
9307 2017-04-25 Justin Squirek <squirek@adacore.com>
9309 * exp_util.adb (Add_Invariant): Removed,
9310 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
9311 and Add_Own_Invariant. (Add_Invariant_Check): Used
9312 for adding runtime checks from any kind of invariant.
9313 (Add_Inherited_Invariant): Generates invariant checks for
9314 class-wide invariants (Add_Interface_Invariants): Removed, code
9315 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
9316 Create a types own invariant procedure (Add_Parent_Invariants):
9317 Removed, code moved to Build_Invariant_Procedure_Body
9318 (Build_Invariant_Procedure_Body): Add refactored calls
9319 and integrated code from Add_Parent_Invariants and
9320 Add_Interface_Invariants.
9321 (Process_Type): Removed, the
9322 relavant code was inlined into both Add_Own_Invariant and
9323 Add_Inherited_Invariant.
9325 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9327 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

9344 and Build_Invariant_Procedure_Declaration.
9345 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
9346 and Build_Invariant_Procedure_Declaration from exp_ch7
9347 and break-out Is_Untagged_Private_Derivation from
9348 Build_Invariant_Procedure_Body.
9349 (Replace_Type_References):
9350 Append an extra parameter to allow for dispatching replacements
9351 and add the corrasponding logic.
9352 (Type_Invariant): Remove
9353 Replace_Typ_Refs and replace its references with calls to
9354 Replace_Type_References.
9355 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
9357 2017-04-25 Bob Duff <duff@adacore.com>
9359 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
9360 that returns True when appropriate.
9361 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
9362 when compiling predefined files.
9363 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
9364 "gnat.adc" should not be considered a predefined file name.
9365 That required (or at least encouraged) a lot of cleanup of global
9366 variable usage. We shouldn't be communicating information via
9367 the global name buffer.
9368 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
9369 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

9389 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove
9390 Add_String_To_Name_Buffer, to avoid using the global Name_Buf.
9391 Add String_To_Name with no side effects.
9393 2017-04-25 Justin Squirek <squirek@adacore.com>
9395 * sem_ch3.adb (Analyze_Declarations): Add
9396 additional condition for edge case.
9398 2017-04-25 Bob Duff <duff@adacore.com>
9400 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
9401 reserved words inside pragmas. This is necessary to allow the
9402 pragma name Interface to be used in pragma Ignore_Pragma.
9403 * par.adb: Minor comment fix.
9405 2017-04-25 Javier Miranda <miranda@adacore.com>
9407 * a-tags.ads, a-tags.adb (Type_Is_Abstract): Renamed as Is_Abstract.

9428 * sem_ch5.adb (Analyze_Assignment): Reset Full_Analysis flag on
9429 the first pass over an assignment statement with target names,
9430 to prevent the generation of subtypes (such as discriminated
9431 record components)that may carry the target name outside of the
9432 tree for the assignment. The subtypes will be generated when
9433 the assignment is reanalyzed in full.

10193 (Check_Dependency_Clause): Properly detect a match between two
10194 'Result attributes. Update the various post-match cases to use

10198 (Remove_Extra_Clauses): New routine.
10199 (Report_Extra_Clauses): Remove the detection of ... => null
10200 clauses as this is now done in Remove_Extra_Clauses.
10202 2017-01-23 Ed Schonberg <schonberg@adacore.com>
10204 * sem_aggr.adb (Resolve_Array_Aggregate): In ASIS mode do not
10205 report on spurious overlaps between values involving a subtype
10206 with a static predicate, because the expansion of such a subtype
10207 into individual ranges in inhibited in ASIS mode.
10209 2017-01-23 Justin Squirek <squirek@adacore.com>
10211 * sem_ch3.adb (Analyze_Declarations): Add detection

10239 to the expected type with the appropriate check flags set.
10240 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
10241 base type if the range is null. It may still be invalid if it
10242 is higher than the lower bound. This is checked later in the
10243 context in which the range appears.
10245 2017-01-23 Pierre-Marie de Rodat <derodat@adacore.com>
10247 * scos.ads: Introduce a constant to represent ignored

10258 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
10259 an object declaration for an array type with a modular index type
10260 with the size of Long_Long_Integer. Special processing is needed
10261 in this case to compute reliably the size of the object, and
10262 eventually to raise Storage_Error, when wrap-around arithmetic
10263 might compute a meangingless size for the object.
10265 2017-01-23 Justin Squirek <squirek@adacore.com>
10267 * a-wtenau.adb, par-endh.adb, sem_prag.adb,

10272 * sem_res.adb (Resolve_Call): In the part of the code where
10273 it is deciding whether to turn the call into an indexed
10274 component, avoid doing so if the call is to an instance of
10275 Unchecked_Conversion. Otherwise, the compiler turns it into an
10276 indexed component, and resolution of that turns it back into a
10277 function call, and so on, resulting in infinite recursion.
10278 * sem_util.adb (Needs_One_Actual): If the first formal has a
10279 default, then return False.
10281 2017-01-21 Eric Botcazou <ebotcazou@adacore.com>

10318 * exp_ch9.adb: minor style fixes in comments.
10319 * sem_ch9.adb (Analyze_Delay_Relative): in GNATprove mode a delay

10324 2017-01-20 Ed Schonberg <schonberg@adacore.com>
10326 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
10327 must be treated as delayed aspect even if the expression is
10328 a literal, because the aspect affects the freezing and the
10329 elaboration of the object to which it applies.
10331 2017-01-20 Tristan Gingold <gingold@adacore.com>
10333 * s-osinte-vxworks.ads (Interrup_Range): New subtype.

10349 * exp_attr.adb (Constrained): Apply an access check (check that
10350 the prefix is not null) when the prefix denotes an object of an

10365 (Prune_Node): Do not prune compilation unit nodes.
10366 (Remove_Ignored_Ghost_Code): Prune the compilation unit node directly.

10376 Ghost when it withs a Ghost unit.
10378 2017-01-20 Javier Miranda <miranda@adacore.com>
10380 * sem_res.adb (Resolve_Call): If a function call
10381 returns a limited view of a type and at the point of the call the
10382 function is not declared in the extended main unit then replace
10383 it with the non-limited view, which must be available. If the
10384 called function is in the extended main unit then no action is
10385 needed since the back-end handles this case.
10387 2017-01-20 Eric Botcazou <ebotcazou@adacore.com>
10389 * sem_ch7.adb (Contains_Subp_Or_Const_Refs): Rename into...

10399 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
10400 base type differs from that of the completion and the private
10401 subtype is an itype (created for a constraint on an access
10402 type e.g.), set Delayed_Freeze on both to prevent out-of-scope
10405 2017-01-20 Hristian Kirtchev <kirtchev@adacore.com>
10407 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
10408 When inheriting the SPARK_Mode of a prior expression function,
10409 look at the properly resolved entity rather than the initial
10410 candidate which may denote a homonym.
10412 2017-01-20 Ed Schonberg <schonberg@adacore.com>
10414 * sem_prag.adb (Rewrite_Assertion_Kind): If the name is
10415 Precondition or Postcondition, and the context is pragma

10904 (Get_Contract_Only_Missing_Body_Name): Removed.
10906 2017-01-13 Javier Miranda <miranda@adacore.com>
10908 * sem_ch6.adb (Cloned_Expression): New subprogram.
10909 (Freeze_Expr_Types): Complete previous patch since the expression
10910 of an expression-function may have iterators and loops with
10911 defining identifiers which, as part of the preanalysis of the
10912 expression, may be left decorated with itypes that will not be
10913 available in the tree passed to the backend.
10915 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10917 * checks.adb (Apply_Type_Conversion_Checks): Optimize a type
10918 conversion to Integer of an expression that is an attribute
10919 reference 'Pos on an enumeration type.
10921 2017-01-13 Bob Duff <duff@adacore.com>
10923 * atree.ads: Minor comment fix.

10928 calls in accessibility check on return statement.
10930 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
10932 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
10933 Ensure that the input body is a subprogram body before trying to
10934 determine whether it denoted an expression function. Note that
10935 subprogram body stubs cannot denote expression functions.
10937 2017-01-13 Gary Dismukes <dismukes@adacore.com>
10939 * bindgen.adb, sem_ch6.adb, binde.adb, exp_ch3.adb: Minor reformatting
10942 2017-01-13 Javier Miranda <miranda@adacore.com>
10944 * einfo.ads (Component_Bit_Offset): Fix documentation.
10945 * sem_ch13.adb (Check_Record_Representation_Clause): Skip check
10946 on record holes for components with unknown compile-time offsets.
10948 2017-01-13 Bob Duff <duff@adacore.com>
10950 * ali.ads, ali.adb (Static_Elaboration_Model_Used): Remove unused flag.
10951 * g-locfil.ads: Minor comment fix.
10953 2017-01-13 Bob Duff <duff@adacore.com>
10955 * binde.adb (Elab_New): New elaboration order algorithm
10956 that is expected to cause fewer ABE issues. This is a work in
10957 progress. The new algorithm is currently disabled, and can be
10958 enable by the -dp switch, or by modifying the Do_Old and Do_New
10959 etc. flags and rebuilding. Experimental code is included to
10960 compare the results of the old and new algorithms.
10961 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
10962 can have multiple of these tables, so the old and new algorithms
10964 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
10965 parameter of type array. This avoids the global variable, and
10966 allows bounds checking (which is normally defeated by the tables
10967 packages). It also ensures that the Elab_Order is read-only
10969 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
10970 subprograms that need it, as above.
10971 * debug.adb: Document new -dp switch. Modify doc of old -do
10973 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
10974 and Bindgen. Move writing of closure (-R and -Ra switches)
10975 to Binde; that's more convenient.
10977 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10979 * sem_ch6.adb (Analyze_Expression_Function): If the expression
10980 function is a completion, all entities referenced in the
10981 expression are frozen. As a consequence, a reference to an
10982 uncompleted private type from an enclosing scope is illegal.
10984 2017-01-13 Javier Miranda <miranda@adacore.com>
10986 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
10987 (Analyze_Subprogram_Body_Helper): At the occurrence of an
10988 expression function declaration that is a completion, its
10989 expression causes freezing (AI12-0103).
10991 2017-01-13 Vadim Godunko <godunko@adacore.com>
10993 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

11000 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11002 * exp_ch3.adb (Default_Initialize_Object): Do not default
11003 initialize an object when it is of a task type and restriction
11004 No_Tasking is in effect because the initialization is obsolete.
11005 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
11006 restriction No_Tasking is in effect.
11007 (Build_Master_Renaming): Do not rename a master when restriction
11008 No_Tasking is in effect.
11010 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11012 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
11013 the legality of An others clause applies as well to a choice in
11014 an Iterated_component_ association.
11015 (Resolve_Iterated_Component_Association): An others choice
11017 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
11018 Iterated_Component_Association is not static.
11020 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11022 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
11023 control is passed to the expresion handler before the new mode
11025 * sem_ch12.adb (Analyze_Package_Instantiation,
11026 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set
11027 in case control is passed to the expresion handler before the

11032 * sem_aggr.adb, sem_ch3.adb, inline.adb, sem_util.adb, exp_ch4.adb,
11033 exp_aggr.adb: Minor reformatting.
11035 2017-01-13 Gary Dismukes <dismukes@adacore.com>
11037 * inline.adb: Minor reformatting and typo fix.
11039 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11041 * sem_util.ads, sem_util.adb (Choice_List): Move function here
11042 from sem_aggr.adb, for use elsewhere.
11043 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
11044 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
11045 Iterated_Component_Present.
11046 * exp_aggr.adb: Use Choice_List throughout, to handle
11047 Iterated_Component_Associations.
11048 (Gen_Loop): Generate proper loop for an
11049 Iterated_Component_Association: loop variable has the identifier
11050 of the original association. Generate a loop even for a single
11051 component choice, in order to make loop parameter visible in
11053 (Flatten): An Iterated_Component_Association is not static.
11055 2017-01-13 Yannick Moy <moy@adacore.com>
11057 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
11058 float exponentiation for statically known small negative values
11059 is the reciprocal of the exponentiation for the opposite value
11061 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
11062 Ensure that the value of float exponentiation for negative values
11063 is the reciprocal of the exponentiation for the opposite value
11065 * inline.adb (Expand_Inlined_Call): Fix the count
11066 for the number of generated gotos.
11068 2017-01-13 Yannick Moy <moy@adacore.com>

11072 expression in delay statement as OK for volatile context.
11074 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11076 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
11077 mode a choice that is a subtype with a static predicate is
11078 replaced by the values it covers. This transformation must not
11079 be performed in ASIS mode, to preserve the source for analysis.
11081 2017-01-13 Justin Squirek <squirek@adacore.com>
11083 * nlists.ads: Correct minor typo.
11085 2017-01-13 Gary Dismukes <dismukes@adacore.com>
11087 * sem_ch13.adb: Minor reformatting and typo fix.
11089 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11091 * par-ch4.adb (P_Aggregate_Or_Parent_Expr): An
11092 Iterated_Component_Association is a named association in an
11094 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
11095 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
11096 and resolve the discrete choices and the expression of the
11098 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
11099 Loop_Actions and Box_Present are attributes of
11100 N_Iterated_Component_Association nodes. Box_Present is always
11101 False in this case.
11102 * sprint.adb (Sprint_Node): An Iterated_Component_Association
11103 has a Discrete_Choices list, as specified in the RM. A
11104 Component_Association for aggregate uses instead a Choices list.
11105 We have to live with this small inconsistency because the new
11106 construct also has a defining identifier, and there is no way
11107 to merge the two node structures.
11109 2017-01-13 Yannick Moy <moy@adacore.com>
11111 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the

11118 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
11119 Analyze_Declarations, to analyze and resolve the expressions of
11120 aspect specifications in the current declarative list, so that
11121 the expressions have proper entity and type info. This is needed
11122 for ASIS when there is no subsequent expansion to generate this
11123 semantic information.
11124 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
11125 original expression, to suppress cascaded errors when expression
11126 has been constant-folded.
11127 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
11128 ASIS mode, because there is no subsequent expansion to decorate
11131 2017-01-13 Yannick Moy <moy@adacore.com>
11133 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
11134 New function to detect when a call may be inlined or not in
11136 (Expand_Inlined_Call): Ensure that a temporary
11137 is always created in the cases where a type conversion may be
11138 needed on an input parameter in GNATprove mode, so that GNATprove
11139 sees the check to perform.
11140 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
11141 when not applicable due to actual requiring type conversion
11142 with possible check but no temporary value can be copied for
11143 GNATprove to see the check.

11321 GNATprove_Mode here to Frontend.
11322 * frontend.adb (Frontend): Move the implicit with for System
11323 in GNATprove_Mode here as it ismore correct this way; the old
11324 place only worked by chance, since there were no overloaded names.
11325 * rtsfind.ads (RE_Id, RE_Unit_Table): Add RE_Tasking_State.
11326 * sem_attr.adb (Analyze_Attribute): In GNATprove_Mode, for the
11327 four attributes identified in SRM 9(18), add an implicit with
