3 * doc/gnat_ugn/gnat_and_program_execution.rst: Update section "Dynamic
4 Stack Usage Analysis" to include more details about GNAT_STACK_LIMIT.
6 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
8 * exp_util.adb (Add_Own_DIC): Ensure that the expression of the pragma
9 is available (Is_Verifiable_DIC_Pragma): Moved from Sem_Util.
10 * sem_util.adb (Has_Full_Default_Initialization):
11 Has_Fully_Default_Initializing_DIC_Pragma is now used to determine
12 whether a type has full default initialization due to pragma
13 Default_Initial_Condition.
14 (Has_Fully_Default_Initializing_DIC_Pragma): New routine.
15 (Is_Verifiable_DIC_Pragma): Moved to Exp_Util.
16 * sem_util.ads (Has_Fully_Default_Initializing_DIC_Pragma): New
18 (Is_Verifiable_DIC_Pragma): Moved to Exp_Util.
19 * sem_warn.adb (Is_OK_Fully_Initialized):
20 Has_Fully_Default_Initializing_DIC_Pragma is now used to determine
21 whether a type has full default initialization due to pragma
22 Default_Initial_Condition.
24 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
26 * sem_prag.adb (Match_Constituent): Do not quietly accept constants as
27 suitable constituents.
28 * exp_util.adb: Minor reformatting.
30 2017-12-15 Ed Schonberg <schonberg@adacore.com>
32 * exp_aggr.adb (In_Place_Assign_OK): Extend the predicate to recognize
33 an array aggregate in an allocator, when the designated type is
34 unconstrained and the upper bound of the aggregate belongs to the base
37 2017-12-15 Bob Duff <duff@adacore.com>
39 * exp_ch6.adb (Expand_N_Extended_Return_Statement,
40 Expand_Simple_Function_Return): Assert that the b-i-p-ness of the
41 caller and callee match. Otherwise, we would need some substantial
42 changes to allow b-i-p calls non-b-i-p, and vice versa.
44 2017-12-15 Ed Schonberg <schonberg@adacore.com>
46 * exp_unst.adb (Unnest_Subprograms): Nothing to do if the main unit is
47 a generic package body. Unnesting is only an issue when generating
48 code, and if the main unit is generic then nested instance bodies have
49 not been created and analyzed, and unnesting will crash in the absence
52 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
54 * inline.adb (Add_Inlined_Body): Do not add a function which is
55 completed by an expression function defined in the same context as the
56 initial declaration because the completing body is not in a package
58 (Is_Non_Loading_Expression_Function): New routine.
60 2017-12-15 Hristian Kirtchev <kirtchev@adacore.com>
62 * debug.adb: Move the functionality of -gnatdL to -gnatd_i. Restore
63 the behavior of -gnatdL from before revision 255412.
64 * sem_elab.adb: Update the section of compiler switches.
65 (Build_Call_Marker): Do not create a marker for a call which originates
66 from an expanded spec or body of an instantiated gener, does not invoke
67 a generic formal subprogram, the target is external to the instance,
68 and -gnatdL is in effect.
69 (In_External_Context): New routine.
70 (Process_Conditional_ABE_Activation_Impl): Update the uses of -gnatdL
72 (Process_Conditional_ABE_Call): Update the uses of -gnatdL and
74 * switch-c.adb (Scan_Front_End_Switches): Switch -gnatJ now sets switch
76 * exp_unst.adb: Minor typo fixes and edits.
78 2017-12-15 Ed Schonberg <schonberg@adacore.com>
80 * sem_ch6.adb (Possible_Freeze): Do not set Delayed_Freeze on an
81 subprogram instantiation, now that the enclosing wrapper package
82 carries an explicit freeze node. THis prevents freeze nodes for the
83 subprogram for appearing in the wrong scope. This is relevant when the
84 generic subprogram has a private or incomplete formal type and the
85 instance appears within a package that declares the actual type for the
86 instantiation, and that type has itself a delayed freeze.
88 2017-12-15 Patrick Bernardi <bernardi@adacore.com>
90 * doc/gnat_ugn/gnat_and_program_execution.rst: Removed references to
91 the environment variable GNAT_STACK_LIMIT from the Stack Overflow
92 Checking section as it is no longer used by any of our supported
95 2017-12-15 Bob Duff <duff@adacore.com>
97 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
98 Init_Assignment is rewritten, we need to set Assignment_OK on the new
99 node. Otherwise, we will get spurious errors when initializing via
100 assignment statement.
102 2017-12-15 Arnaud Charlet <charlet@adacore.com>
104 * exp_unst.adb (Visit_Node): Refine handling of 'Access to ignore non
106 (Has_Non_Null_Statements): Moved to sem_util for later reuse.
108 2017-12-15 Eric Botcazou <ebotcazou@adacore.com>
110 * exp_attr.adb (Is_Inline_Floating_Point_Attribute): Fix comment.
111 * libgnat/s-fatgen.adb (Model): Use Machine attribute.
112 (Truncation): Likewise.
114 2017-12-15 Bob Duff <duff@adacore.com>
116 * exp_ch7.adb (Expand_Cleanup_Actions): Make sure the block and handled
117 statement sequence generated for certain extended return statements
118 have a Sloc that is not No_Location. Otherwise, the back end doesn't
119 set any location and ends up reading uninitialized variables.
121 2017-12-15 Bob Duff <duff@adacore.com>
123 * types.ads, exp_ch6.adb, libgnat/s-regexp.ads, opt.ads: Partly revert
124 r255414, committed by mistake.
126 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
128 * gcc-interface/Makefile.in: Generalize support for symbolic traces.
130 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
132 * gcc-interface/misc.c (default_pass_by_ref): Minor tweak.
134 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
136 * gcc-interface/trans.c (Call_to_gnu): Set DECL_DISREGARD_INLINE_LIMITS
137 to 0 on the callee if the call is recursive.
139 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
141 * gcc-interface/decl.c (gnat_to_gnu_field): Do not set the alignment
142 of the enclosing record type if it is not already set.
144 2017-12-14 Eric Botcazou <ebotcazou@adacore.com>
146 * gcc-interface/gigi.h (pad_type_has_rm_size): Declare.
147 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Do not build
148 a padding type for the alignment before validating the size.
149 Flip conditional construct and add a comment.
150 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Size>: Make sure to
151 apply the exception for padded objects to the type of the object.
152 * gcc-interface/utils.c (hash_pad_type): New static function.
153 (lookup_and_insert_pad_type): Rename into...
154 (canonicalize_pad_type): ...this. Call hash_pad_type, do only one
155 lookup with insertion and always return the canonical type.
156 (maybe_pad_type): Adjust to above changes. Set debug type later.
157 (pad_type_has_rm_size): New predicate.
158 (set_reverse_storage_order_on_pad_type): Adjust to above changes.
160 2017-12-13 Eric Botcazou <ebotcazou@adacore.com>
162 * gcc-interface/trans.c (Subprogram_Body_to_gnu): Initialize locus.
164 2017-12-13 Eric Botcazou <ebotcazou@adacore.com>
166 * gcc-interface/trans.c (process_freeze_entity): Be prepared for a
167 package without body.
169 2017-12-13 Eric Botcazou <ebotcazou@adacore.com>
171 * gcc-interface/decl.c (gnat_to_gnu_entity): Robustify test for types
172 descendant of System.Address.
173 (gnat_to_gnu_subprog_type): Likewise.
175 2017-12-08 Jakub Jelinek <jakub@redhat.com>
177 * gcc-interface/utils.c (gnat_internal_attribute_table): Add
178 exclusions to the comment.
180 2017-12-07 Martin Sebor <msebor@redhat.com>
183 * gcc-interface/utils.c (gnat_internal_attribute_table): Initialize
184 new member of struct attribute_spec.
186 2017-12-06 Simon Wright <simon@pushface.org>
189 * bindgen.adb (Gen_AdaFinal): If the restriction No_Task_Termination is
190 set, generate a null body.
192 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
194 * sem_util.adb (Contains_Refined_State): Remove.
196 2017-12-05 Ed Schonberg <schonberg@adacore.com>
198 * sem_ch13.adb (Analyze_Aspect_Specifications, case Predicate): A
199 predicate cannot apply to a formal type.
201 2017-12-05 Arnaud Charlet <charlet@adacore.com>
203 * exp_unst.ads: Fix typos.
205 2017-12-05 Jerome Lambourg <lambourg@adacore.com>
207 * libgnarl/s-taprop__qnx.adb: Better detect priority ceiling bug in
208 QNX. At startup, the first mutex created has a non-zero ceiling
209 priority whatever its actual policy. This makes some tests fail
210 (c940013 for example).
212 2017-12-05 Bob Duff <duff@adacore.com>
214 * exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Call
215 Expand_Cleanup_Actions for N_Extended_Return_Statement.
216 * exp_ch7.adb (Expand_Cleanup_Actions): Handle
217 N_Extended_Return_Statement by transforming the statements into a
218 block, and (indirectly) calling Expand_Cleanup_Actions on the block.
219 It's too hard for Expand_Cleanup_Actions to operate directly on the
220 N_Extended_Return_Statement, because it has a different structure than
221 the other node kinds that Expand_Cleanup_Actions.
222 * exp_util.adb (Requires_Cleanup_Actions): Add support for
223 N_Extended_Return_Statement. Change "when others => return False;" to
224 "when others => raise ...;" so it's clear what nodes this function
225 handles. Use named notation where appropriate.
226 * exp_util.ads: Mark incorrect comment with ???.
228 2017-12-05 Javier Miranda <miranda@adacore.com>
230 * exp_ch9.adb (Install_Private_Data_Declarations): Add missing
231 Debug_Info_Needed decoration of internally generated discriminal
232 renaming declaration.
234 2017-12-05 Arnaud Charlet <charlet@adacore.com>
236 * exp_unst.adb (Unnest_Subprogram): Add handling of 'Access on
239 2017-12-05 Sergey Rybin <rybin@adacore.com>
241 * doc/gnat_ugn/gnat_utility_programs.rst: Add description of '--ignore'
242 option for gnatmetric, gnatpp, gnat2xml, and gnattest.
244 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
246 * sem_util.adb (Contains_Refined_State): Remove.
248 2017-12-05 Piotr Trojanek <trojanek@adacore.com>
250 * rtsfind.ads: Add new enumeration literals: RE_Clock_Time (for
251 Ada.Real_Time.Clock_Time) and RO_CA_Clock_Time (for
252 Ada.Calendar.Clock_Time).
254 2017-12-05 Ed Schonberg <schonberg@adacore.com>
256 * sem_ch4.adb (Is_Private_Overriding): If the candidate private
257 subprogram is overloaded, scan the list of homonyms in the same
258 scope, to find the inherited operation that may be overridden
260 * exp_ch11.adb, exp_ch7.adb: Minor reformatting.
262 2017-12-05 Bob Duff <duff@adacore.com>
264 * exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
265 Init_Assignment is rewritten, we need to set Assignment_OK on the new
266 node. Otherwise, we will get spurious errors when initializing via
267 assignment statement.
269 2017-12-05 Hristian Kirtchev <kirtchev@adacore.com>
271 * sem_elab.adb: Update the terminology and switch sections.
272 (Check_SPARK_Model_In_Effect): New routine.
273 (Check_SPARK_Scenario): Verify the model in effect for SPARK.
274 (Process_Conditional_ABE_Call_SPARK): Verify the model in effect for
276 (Process_Conditional_ABE_Instantiation_SPARK): Verify the model in
278 (Process_Conditional_ABE_Variable_Assignment_SPARK): Verify the model
281 2017-12-05 Nicolas Setton <setton@adacore.com>
283 * terminals.c (__gnat_setup_child_communication): As documented,
284 __gnat_setup_child_communication should not terminate - it is intended
285 to be used as the child process of a call to fork(). However, execvp
286 might actually return in some cases, for instance when attempting to
287 run a 32-bit binary on a 64-bit Linux distribution when the
288 compatibility packages are not installed. In these cases, exit the
289 program to conform to the documentation.
291 2017-12-05 Olivier Hainque <hainque@adacore.com>
293 * libgnat/s-tsmona.adb: Fix for oversight in the tsmona interface
296 2017-12-05 Gary Dismukes <dismukes@adacore.com>
298 * doc/gnat_ugn/elaboration_order_handling_in_gnat.rst: Minor typo fix
300 * gnat_ugn.texi: Regenerate.
302 2017-12-05 Olivier Hainque <hainque@adacore.com>
304 * sem_util.adb (Set_Convention): Always clear Can_Use_Internal_Rep
305 on access to subprogram types with foreign convention.
307 2017-12-05 Yannick Moy <moy@adacore.com>
309 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Fix User's
310 Guide description of default settings of warnings.
312 2017-12-05 Olivier Hainque <hainque@adacore.com>
314 * s-dwalin.adb (Read_And_Execute_Isn): Adjust test checking for the end
315 of section. Add comments explaining the rationale of the computation.
317 2017-12-05 Bob Duff <duff@adacore.com>

362 Update the documentation on elaboration-related compilation
363 switches. Update the documentation on adding a new target. Add
364 Processing_Attributes which represent the state of the Processing
365 phase. Resurrect the previous elaboration model as "legacy elaboration
367 (Build_Call_Marker): This routine does not function when the legacy
368 elaboration model is in effect. Do not consider entry calls and requeue
369 statements when debug flag d_e is in effect. Do not consider calls to
370 subprograms which verify the runtime semantics of certain assertion
371 pragmas when debug flag d_p is in effect.
372 (Build_Variable_Reference_Marker): This routine does not function when
373 the legacy elaboration model is in effect.
374 (Check_Elaboration_Scenarios): This routine does not function when the
375 legacy elaboration model is in effect.
376 (Ensure_Prior_Elaboration): The various flags have now been replaced
377 with a state. Do not generate implicit Elaborate[_All] pragmas when
378 their creation has been suppressed.
379 (Ensure_Prior_Elaboration_Static): The with clause is marked based on
380 the requested pragma, not on the nature of the scenario.
381 (In_External_Context): Removed.
382 (Is_Assertion_Pragma_Target): New routine.
383 (Is_Potential_Scenario): Stop the traversal of a task body when
384 reaching an accept or select statement, and debug switch d_a is in
386 (Kill_Elaboration_Scenario): This routine does not function when the
387 legacy elaboration model is in effect.
388 (Process_Activation_Generic): The various flags have now been replaced
390 (Process_Conditional_ABE): The various flags have now been replaced
392 (Process_Conditional_ABE_Access): The various flags have now been
393 replaced with a state.
394 (Process_Conditional_ABE_Activation_Impl): The various flags have now
395 been replaced with a state. Do not process an activation call which

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

451 * doc/gnat_ugn/platform_specific_information.rst: Minor edit.
452 Improve doc on required packages for linux 32bits.
454 2017-12-05 Doug Rupp <rupp@adacore.com>
456 * tracebak.c (ppc64-vx7): USE_GCC_UNWINDER for 64bit.
458 2017-12-05 Javier Miranda <miranda@adacore.com>
460 * checks.adb (Generate_Range_Check): Force evaluation of the node in
461 more cases. This patch was written to improve the code generated by
462 the CCG compiler but it is enabled for all targets since double
463 evaluation is always a potential source of inefficiency.
465 2017-12-05 Gary Dismukes <dismukes@adacore.com>
467 * doc/gnat_ugn/gnat_utility_programs.rst: Remove reference to obsolete
470 2017-12-05 Eric Botcazou <ebotcazou@adacore.com>
472 * exp_ch5.adb (Expand_Iterator_Loop_Over_Array): Use the SLOC of the
473 iteration scheme throughout, except for the new loop statement(s).
475 2017-12-05 Ed Schonberg <schonberg@adacore.com>
477 * exp_aggr.adb (Gen_Assign): Do not analyze the expressionn of the
478 assignment if it is part of an Iterated_Component_Association: the
479 analysis needs to take place once the loop structure is analyzed and
480 the loop parameter made visible, because references to it typically
481 appear in the corresponding expression. This is necessary if the
482 expression is an aggregate, because previous pre-analysis of the
483 expression does not handle nested aggregates properly.
485 2017-12-05 Bob Duff <duff@adacore.com>
487 * sem_res.adb (Resolve_Allocator): Avoid coextension processing for an
488 allocator that is the expansion of a build-in-place function call.
490 2017-12-05 Olivier Hainque <hainque@adacore.com>
493 * s-trasym__dwarf.adb (spec of Module_Name.Get): Instead of
494 possibly adjusting the lookup address by a load address, expect
495 a extra argument through which the load address can be conveyed
497 (Multi_Module_Symbolic_Traceback): Adjust accordingly. Pass the
498 retrieved load address to Init_Module.
499 * s-tsmona__linux.adb (Get): Honor the new interface.
500 * s-tsmona__mingw.adb (Get): Likewise.
501 * s-dwalin.ads: Adjust comments to be explicit about which
502 addresses are from module info and which are run-time addresses,
503 offsetted by the module load address.
504 * s-dwalin.adb (Set_Load_Address): Simply set C.Load_Slide.
505 Do not alter the module Low and High (relative) addresses.
506 (Is_Inside): Improve documentation regarding the kinds of addresses
507 at hand and correct the test.
508 (Symbolic_Traceback): Use separate variables with explicit names
509 for the address in traceback (run-time value) and the address to
510 lookup within the shared object (module-relative). Adjust the
511 computation of address passed to Symbolic_Address for symbolization.
513 2017-12-05 Arnaud Charlet <charlet@adacore.com>
515 * opt.ads (Expand_Nonbinary_Modular_Ops): New flag.
516 * exp_ch4.adb (Expand_Nonbinary_Modular_Op): Use
517 Expand_Nonbinary_Modular_Ops instead of Modify_Tree_For_C, so that
518 other back-ends can also benefit from the front-end expansion. Remove
519 test for Modify_Tree_For_C in all callers to better share code.
520 * gnat1drv.adb (Adjust_Global_Switches): Set
521 Expand_Nonbinary_Modular_Ops when generating C code.
523 2017-12-05 Ed Schonberg <schonberg@adacore.com>
525 * exp_ch5.adb (Expand_Formal_Container_Loop): Ensure that the loop
526 parameter becomes invisible after analyzing the loop, which has been
527 rewritten as a while-loop.
529 2017-12-05 Doug Rupp <rupp@adacore.com>
531 * vxaddr2line.adb: Revise and enhance for new ports, remove dead ports,

1059 * libgnarl/s-osinte__qnx.ads: Add some missing bindings to pthread.
1060 * libgnarl/s-taprop__qnx.adb: New, derived from s-taprop__posix.adb. This brings
1061 in particular a workaround with locks priority ceiling where a higher
1062 priority task is allowed to lock a lower ceiling priority lock. This
1063 also fixes the scheduling of FIFO tasks when the priority of a task is
1065 * libgnat/system-qnx-aarch64.ads: Fix priority ranges.

1071 * gnatbind.adb (Scan_Bind_Arg): Simplify test to remove always true
1073 * namet.adb (Copy_One_Character): Add assumption for static analysis,
1074 as knowledge that Hex(2) is in the range 0..255 is too complex for
1076 (Finalize): Add assumption for static analysis, as the fact that there
1077 are symbols in the table depends on a global invariant at this point in
1079 * set_targ.adb (Check_Spaces): Justify CodePeer false positive message.
1080 * stylesw.adb (Save_Style_Check_Options): Rewrite to avoid test always
1083 2017-11-09 Javier Miranda <miranda@adacore.com>
1085 * libgnat/s-rident.ads (Static_Dispatch_Tables): New restriction name.
1086 * exp_disp.adb (Building_Static_DT): Check restriction.
1087 (Building_Static_Secondary_DT): Check restriction.
1088 (Make_DT): Initialize the HT_Link to No_Tag.
1089 * opt.ads (Static_Dispatch_Tables): Rename flag...

1123 * exp_util.adb (Find_Interface_Tag): Default initialize AI_Tag.
1124 * freeze.adb (Check_Component_Storage_Order): Default initialize
1125 Comp_Byte_Aligned rather than silencing messages with pragma
1126 Warnings(Off), which does not work for CodePeer initialization
1127 messages, and given that here the possible read of an unitialized value
1128 depends on a proper use of parameters by the caller.
1129 * inline.adb (Expand_Inlined_Call): Default initialize Lab_Decl, Targ.
1130 * sem_ch12.adb (Build_Operator_Wrapper): Default initialize Expr.

1139 * sem_ch6.adb (Analyze_Function_Return): Default initialize Obj_Decl,
1140 and restructure code to defend against previous errors, so that, in
1141 that case, control does not flow to the elsif condition which read an
1142 uninitialized Obj_Decl.
1143 * sem_ch9.adb (Analyze_Requeue): Default initialize Synch_Type.
1144 (Check_Interfaces): Default initialize Full_T_Ifaces and Priv_T_Ifaces,
1145 which seem to be left uninitialized and possibly read in some cases.
1146 * sem_dim.adb (Analyze_Aspect_Dimension_System): Retype Position more
1147 precisely. This requires to exchange the test for exiting in case of
1148 too many positions and the increment to Position, inside the loop.
1149 * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,
1150 which cannot be read uninitialized, but the reasons for that are quite
1152 * sem_intr.adb (Check_Intrinsic_Call): Default initialize Rtyp.
1153 * sem_prag.adb (Collect_Subprogram_Inputs_Outputs): Default initialize
1155 * sem_res.adb (Make_Call_Into_Operator): Default initialize Opnd_Type,
1156 and test for presence of non-null Opnd_Type before testing its scope,
1157 in a test which would read its value uninitialized, and is very rarely
1158 exercized (it depends on the presence of an extension of System).

1162 * set_targ.adb (FailN): Mark procedure with No_Return.

1170 * exp_ch11.adb (Possible_Local_Raise): Do not issue the warning for

1194 * namet.ads, namet.adb (Valid_Name_Id): New subtype that excludes
1195 Error_Name and No_Name. Use this (versus Name_Id) to indicate which
1196 objects can have those special values. Valid_Name_Id could usefully be
1197 used all over the compiler front end, but that's too much trouble for
1198 now. If we did that, we might want to rename:
1199 Name_Id --> Optional_Name_Id, Valid_Name_Id --> Name_Id.
1200 For parameters of type Valid_Name_Id, remove some redundant tests,
1201 including the ones found by CodePeer. Use Is_Valid_Name instead of
1202 membership test when appropriate.
1203 (Error_Name_Or_No_Name): Delete this; it's no longer needed.
1204 * sem_ch2.adb (Analyze_Identifier): Use "not Is_Valid_Name" instead of
1205 "in Error_Name_Or_No_Name".
1206 (Check_Parameterless_Call): Use "not Is_Valid_Name" instead of "in

2601 * sem_util.adb (Object_Access_Level): If the object is the return
2602 statement of an expression function, return the level of the function.
2603 This is relevant when the object involves an implicit conversion
2604 between access types and the expression function is a completion, which
2605 forces the analysis of the expression before rewriting it as a body, so
2606 that freeze nodes can appear in the proper scope.

2631 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Add self-checking

2635 as for the other Is_B-I-P... functions.

2641 creating an Itype for a library unit entity.

2643 internally-generated call.
2644 * sem_ch5.adb (Analyze_Assignment): Handle the case where the
2645 right-hand side is a build-in-place call. This didn't happen when b-i-p
2646 was only for limited types.
2647 * sem_ch6.adb (Create_Extra_Formals): Remove assumption that b-i-p
2648 implies >= Ada 2005.

2678 a freeze node for the instance of the parent if it appears in the same
2679 scope and is not frozen yet.
2681 2017-10-09 Pierre-Marie de Rodat <derodat@adacore.com>
2683 * exp_atag.ads, libgnat/a-tags.adb, libgnat/a-tags.ads: Enhance
2684 in-source documentation for tagged types's Offset_To_Top.
2686 2017-10-09 Bob Duff <duff@adacore.com>
2688 * exp_ch3.adb (Build_Assignment): Parameter name N was somewhat
2689 confusing. Same for N_Loc. Remove assumption that b-i-p implies
2690 limited. This is for the case of a function call that occurs as the
2691 default for a record component.
2692 (Expand_N_Object_Declaration): Deal with the case where expansion has
2693 created an object declaration initialized with something like

2699 * exp_attr.adb (Expand_Attribute_Reference, case 'Valid): The prefix of
2700 the attribute is an object, but it may appear within a conversion. The
2701 object itself must be retrieved when generating the range test that
2702 implements the validity check on a scalar type.

2763 (Is_Build_In_Place_Result_Type): New function to accompany
2764 Is_Build_In_Place_Function and Is_Build_In_Place_Function_Call, because
2765 sometimes we just have the type on our hands, not the function. For
2766 now, does the same thing as the old version, so build-in-place is
2767 disabled for nonlimited types, except that you can use -gnatd.9 to
2769 * exp_ch6.ads (Is_Build_In_Place_Result_Type): New function to
2770 accompany Is_Build_In_Place_Function and

2784 an unchecked conversion. Add assertions.

3799 2017-09-08 Yannick Moy <moy@adacore.com>
3801 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
3802 return the entity associated with the call.
3803 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
3804 Replace the internal Get_Function_Id with the new
3805 Sem_Aux.Get_Called_Entity.
3806 (Iterate_Call_Parameters): New
3807 procedure to iterate on formals and actuals at the same time.
3808 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
3809 Set SPARK_Mode from spec when set, for analysis
3810 of instance. Restore after analysis of instance.
3811 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
3812 set, for analysis of body instance. Restored automatically at
3813 the end of the subprogram.

3821 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
3822 (New_Copy_Tree): ...there. Reset the hash tables only if they
3823 were used in the previous invocation.
3824 * s-htable.adb: Fix typo.
3826 2017-09-08 Bob Duff <duff@adacore.com>
3828 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
3830 2017-09-08 Arnaud Charlet <charlet@adacore.com>
3832 * sem_aggr.adb: minor style fix.
3834 2017-09-08 Bob Duff <duff@adacore.com>
3836 * sprint.adb (Write_Corresponding_Source): Ignore if there is
3837 no current source file.
3838 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
3839 Print something helpful in case N is invalid.
3840 * sprint.ads: Minor comment fix.
3842 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3844 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
3847 2017-09-08 Bob Duff <duff@adacore.com>
3849 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
3850 Ada_2020, along the same lines as the other Ada version pragmas.
3852 2017-09-08 Gary Dismukes <dismukes@adacore.com>
3854 * sem_ch12.adb: Minor typo fixes and reformatting.
3856 2017-09-08 Yannick Moy <moy@adacore.com>
3858 * sem_aggr.adb (Resolve_Record_Aggregate):
3859 Rewrite bounds of aggregate subexpressions which may depend on
3860 discriminants of the enclosing aggregate.
3862 2017-09-08 Yannick Moy <moy@adacore.com>
3864 * sem_ch5.adb: Prevent assertion failure on illegal code.
3866 2017-09-08 Yannick Moy <moy@adacore.com>
3868 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
3869 calling Renamed_Entity on an entity which cannot be a renaming.
3871 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3873 * exp_aggr.adb: Add with & use clause for Urealp.
3874 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
3875 elementary types instead of just discrete types.
3876 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
3877 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
3878 Be prepared for the FP zero value in the memset case. Add small
3881 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3883 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
3886 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
3888 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
3889 of New_Copy because the latter leaves the syntactic structure of
3890 the tree inconsistent (a child is accessible through two parents)
3891 and prevents proper replication of itypes by subsequent calls
3893 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
3894 New_Copy because the latter leaves the syntactic structure of the
3895 tree inconsistent (a child is accessible through two parents)
3896 and prevents proper replication of itypes by subsequent calls
3898 * sem_util.adb (In_Subtree): New routine.
3899 (New_Copy_Tree): Reimplemented.
3900 * sem_util.ads (In_Subtree): New routine.

3905 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
3906 for aspect Default_Value is a static scalar value, but it does
3907 not freeze the type. Yhis allows for subsequent representation
3908 clauses for the type.
3910 2017-09-08 Javier Miranda <miranda@adacore.com>
3912 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
3913 not add entries into the undefined reference table when we are
3914 compiling with errors ignored.
3916 2017-09-08 Ed Schonberg <schonberg@adacore.com>
3918 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
3919 check if the instance is within an enclosing instance body. The
3920 formal package was legal in the enclosing generic, and is
3921 legal in the enclosing instantiation. This optimisation may be
3922 applicable elsewhere, and it also removes spurious errors that
3923 may arise with on-the-fly processing of instantiations that
3924 contain Inline_Always subprograms.
3926 2017-09-08 Vincent Celier <celier@adacore.com>
3928 * gnatcmd.adb: Disregard empty argument of GNAT driver.
3930 2017-09-08 Justin Squirek <squirek@adacore.com>
3932 * checks.adb (Insert_Valid_Check): Manually decorate
3933 the generated temporary for range valdity checks.
3935 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
3937 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
3939 2017-09-08 Justin Squirek <squirek@adacore.com>
3941 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
3942 case to handle underscore flags.
3943 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
3944 new procedure to handle underscores.
3946 2017-09-08 Javier Miranda <miranda@adacore.com>
3948 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
3949 divisions with fixed point results to avoid generating twice
3950 the runtime check on divide by zero.
3951 * checks.adb (Apply_Divide_Checks): Ensure that operands are
3952 not evaluated twice (once for their runtime checks and once for
3953 their regular computation).
3955 2017-09-08 Yannick Moy <moy@adacore.com>
3957 * sem_prag.adb (Analyze_Part_Of): Add missing
3958 return statements after issuing errors. Add detection of
3959 out-of-order item and single concurrent type.

4413 * a-cbdlli.adb, a-cohama.adb, a-cohase.adb (Copy): Rewrite the
4414 code so it doesn't trigger an "uninit var" warning.
4416 2017-09-08 Nicolas Roche <roche@adacore.com>
4418 * s-hibaen.ads: Remove obsolete file.
4420 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4422 * a-locale.ads: Add comment explaining the state of this package.
4424 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4426 * sem_util.adb (Is_CCT_Instance): Allow calls in the context
4428 * sem_prag.ads, sem_prag.adb (Find_Related_Declaration_Or_Body):
4429 allow calls in the context of package spec (for pragma
4430 Initializes) and bodies (for pragma Refined_State).
4432 2017-09-08 Bob Duff <duff@adacore.com>
4434 * checks.adb (Insert_Valid_Check): Copy the Do_Range_Check flag to the
4437 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
4439 * debug.adb (dA): Adjust comment.
4440 * gnat1drv.adb (Gnat1drv): Likewise.
4441 * opt.ads (List_Representation_Info_Extended): New variable.
4442 * repinfo.adb (List_Record_Info): Split implementation into...
4443 (Compute_Max_Length): ...this. Recurse on records if requested.
4444 (List_Record_Layout): Likewise.
4445 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
4446 statement, accept '0' and set List_Representation_Info_Extended
4448 * usage.adb (Usage): Document new -gnatRe variant.
4450 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4452 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
4453 Do not save the given entity in the global variable Default_Pool
4454 if the pragma appears within a generic unit.
4456 2017-09-08 Bob Duff <duff@adacore.com>
4458 * errout.adb (Delete_Warning): Do not
4459 decrement Warnings_Treated_As_Errors. This is called before
4460 Warnings_Treated_As_Errors has been incremented to account for
4461 this warning. Decrementing it here can lead to negative values
4462 of Warnings_Treated_As_Errors, raising Constraint_Error in
4463 checks-on builds, and causing the compiler to return an error
4464 code in checks-off builds.
4466 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4468 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
4469 entities of named concurrent types as Ref_Id and not of anonymous
4470 concurrent objects (because callers already know when a conversion
4471 is necessary and can easily do it); also, do not expect protected
4472 types or protected objects as Context_Id (because no flow-related
4473 SPARK pragmas are attached there); reflect these changes in a
4474 more precise comment.
4476 2017-09-08 Olivier Hainque <hainque@adacore.com>
4478 * g-altive.ads: Add documentation.
4480 2017-09-08 Bob Duff <duff@adacore.com>
4482 * sem_util.ads, debug.adb: Minor comment fix.
4483 * erroutc.ads: Comment fix.
4485 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4487 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
4488 for compatibility of component types of formal and actual in an
4489 instantiation of a child unit, when the component type of the
4490 formal is itself a formal of an enclosing generic.
4492 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4494 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
4495 sem_prag.adb to make it available for GNATprove; for concurrent
4496 types replace custom scope climbing with Scope_Same_Or_Within; for
4497 single concurrent objects add scope climbing (with Scope_Within),
4498 which was not there (that's the primary semantic change of this
4499 commit); also, when comparing a single concurrent object with
4500 its corresponding concurrent type rely on equality of types,
4501 not of objects (because that's simpler to code).
4502 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
4503 (Analyze_Global_Item): adjust special-casing of references to the
4504 current instance of a concurrent unit in the Global contracts
4505 of task types and single tasks objects; similar for references
4506 in the protected operations and entries of protected types and
4507 single protected objects (in all these cases the current instance
4508 behaves as an implicit parameter and must not be mentioned in
4509 the Global contract).
4511 2017-09-08 Arnaud Charlet <charlet@adacore.com>
4513 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
4514 function calls returning a record within a subprogram call,
4517 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4519 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
4520 name that designates the current instance of a child unit in its
4521 own body and appears as the prefix of a reference to an entity
4522 local to the child unit.
4523 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
4526 2017-09-08 Yannick Moy <moy@adacore.com>
4528 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that
4531 2017-09-08 Tristan Gingold <gingold@adacore.com>
4533 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
4534 warnings on internal units in configurable run time mode.
4536 2017-09-08 Bob Duff <duff@adacore.com>
4538 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
4539 representation items from interfaces that the derived type
4540 implements, not just from the parent type.
4541 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
4542 this to return an empty list when there are no interfaces.
4543 * einfo.ads, sem_ch13.adb: Minor comment fixes.
4544 * sem_attr.adb: Minor comment fix.
4546 2017-09-08 Doug Rupp <rupp@adacore.com>
4548 * sigtramp-vxworks.c [i386]: Adjust the kernel context for
4551 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4553 * exp_ch4.adb (Expand_N_Allocator): Generate a
4554 call to Allocate_Any_Controlled when the allocation does not
4555 require any initialization.
4557 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4559 * sem_util.adb (Copy_Node_With_Replacement):
4560 Update the Renamed_Object field of a replicated object renaming
4563 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
4565 * exp_ch9.adb (Is_Pure_Barrier): Allow type
4566 conversions and components of objects. Simplified the detection
4567 of the Count attribute by identifying the corresponding run-time
4570 2017-09-08 Yannick Moy <moy@adacore.com>
4572 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
4573 sem_type.adb, sinfo.ads: Minor reformatting.
4575 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4577 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
4578 of Freeze_Profile, used to inhibit the freezing of the profile
4579 of an expression function declared within a nested package, when
4580 some type in the profile depends on a private type declared in
4581 an enclosing package.
4583 2017-09-08 Bob Duff <duff@adacore.com>
4585 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
4586 the subunit case. It's still OK to set it in the "missing subunits"
4587 case, because that won't cause the obsolete .ali files that cause
4590 2017-09-08 Bob Duff <duff@adacore.com>
4592 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
4593 unclear why this didn't cause a warning.
4594 * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
4595 pragmas. It's unclear why this didn't cause an error.
4597 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4599 * exp_spark.adb (Expand_SPARK_N_Object_Renaming_Declaration):
4601 (Expand_SPARK_Potential_Renaming): Code clean up.
4602 * sem_prag.adb (Analyze_Initialization_Item): Add a guard in case
4603 the item does not have a proper entity.

4621 * repinfo.adb (List_Record_Info): During first loop,
4622 do not override the normalized position and first bit
4623 if they have already been set. Move fallback code
4624 for the packed case to the case where it belongs.
4625 * sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
4626 Also adjust the normalized position of components.
4627 (Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise.
4629 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4631 * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
4632 the placement of a primitive operation O that renames an operation
4633 R declared in an inner package, and which is thus not a primitive
4634 of the dispatching type of O. In this case O is a new primitive
4635 and does not inherit its dispatch table position from R (which

4640 * sem_dim.adb (Analyze_Dimension_If_Expression,
4641 Analyze_Dimension_Case_Expression): new subprograms to verify
4642 the dimensional correctness of Ada2012 conditional expressions,
4643 and set properly the dimensions of the construct.
4644 * sem_res.adb (Resolve_If_Expression, Resolve_Case_Expression)):
4645 call Analyze_Dimension.
4647 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4649 * sem_type.adb (Expand_Interface_Conversion): Prevent an infinite
4650 loop on an interface declared as a private extension of another
4651 synchronized interface.
4653 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4655 * sem_ch12.adb (Check_Generic_Parent): New procedure within
4656 Analyze_Associations, to handle actual packages that depend on
4657 previous instances. If a package IAP that is an instantiation is
4658 used as an actual in a subsequent instantiation SI in the same
4659 scope, and IAP has a body, IAP must be frozen before SI. If
4660 the generic parent of IAP is itself declared in a previous
4661 instantiation in the same scope, that instantiation must also
4662 be frozen before SI.
4663 (Install_Body): Prevent double insertion of freeze node for
4666 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
4668 * sem_prag.adb (Resolve_State): Update the

4674 * sem_ch13.adb (Analyze_Aspect_Specifications, case
4675 Linker_Section): If the aspect applies to an object declaration
4676 with explicit initialization, do not delay the freezing of the
4677 object, to prevent access-before-elaboration in the generated
4678 initialization code.
4680 2017-09-08 Ed Schonberg <schonberg@adacore.com>
4682 * a-wtdeio.adb (Put, all versions): Use Long_Long_Integer
4683 (Integer_Value (Item)) when the size of the fixed decimal type
4684 is larger than Integer.
4686 2017-09-07 Eric Botcazou <ebotcazou@adacore.com>
4689 * gcc-interface/decl.c (copy_and_substitute_in_layout): Put the fields
4690 in order of increasing position in more cases.

4717 * exp_disp.adb (Make_Tags): Avoid suffix counter
4718 in the external name of the elaboration flag. Required to fix
4719 the regressions introduced by the initial version of this patch.
4721 2017-09-07 Bob Duff <duff@adacore.com>
4723 * sem_ch6.adb (Analyze_Function_Return): Do not
4724 insert an explicit conversion to force the displacement of the
4725 "this" pointer to reference the secondary dispatch table in the
4726 case where the return statement is returning a raise expression,
4727 as in "return raise ...".
4729 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4731 * sem_disp.adb (Is_User_Defined_Equality): Removed procedure.
4732 * sem_util.ads, sem_util.adb (Is_User_Defined_Equality): Copied

4751 to handle properly various cases of type conversions where the
4752 target type and/or the expression carry dimension information.
4753 (Dimension_System_Root); If a subtype carries dimension
4754 information, obtain the source parent type that carries the

4759 * g-socket.adb, g-socket.ads (GNAT.Sockets.To_Ada): New routine.
4761 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4763 * exp_attr.adb (Expand_N_Attribute_Reference, case 'Constrained):
4764 If the prefix is a reference to an object, rewrite it as an
4765 explicit dereference, as required by 3.7.2 (2) and as is done
4766 with most other attributes whose prefix is an access value.
4768 2017-09-07 Bob Duff <duff@adacore.com>
4770 * par-ch13.adb: Set the Inside_Depends flag if we are inside a
4771 Refined_Depends aspect.

4780 Account for the case where the are no lists to insert, but the
4781 secondary stack still requires management.

4817 * exp_disp.adb (Replace_Formals): If thr formal is classwide,
4818 and thus not a controlling argument, preserve its type after
4819 rewriting because it may appear in an nested call with a classwide
4822 2017-09-07 Arnaud Charlet <charlet@adacore.com>
4824 * comperr.adb (Delete_SCIL_Files): Handle case of

4830 clause for a unit U appears in a context that includes a regular
4831 with_clause on U, rewrite the redundant private clause into a null
4832 statement, rather than removing it altogether from the context,
4833 so that ASIS tools can reconstruct the original source.

4837 * sem_ch13.adb (Check_Aspect_At_Freeze_Point): The expression
4838 for aspect Small can be of any real type (not only a universal

4882 attribute. Defined for record types and subtypes.
4883 * exp_ch3.ads (Init_Secondary_Tags): Adding new formal

4885 IP routine to initialize the object components and for completing
4886 the elaboration of dispatch tables.
4887 * exp_ch3.adb (Build_Init_Procedure): Improve the code
4888 generated in the IP routines by means of keeping separate
4889 the initialization of the object components from the
4890 initialization of its dispatch tables. (Init_Secondary_Tags):
4891 Adding new formal (Init_Tags_List) and adjusting calls to
4892 Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;
4893 adjusting also calls to Ada.Tags.Register_Interface_Offset
4894 because the type of one of its formals has been changed.
4895 * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
4896 modified. Instead of receiving a pointer to an object this
4897 routine receives now a primary tag.
4898 (Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an

4916 (because it refers to the anonymous concurrent object, not its type);
4917 fix condition for emitting error message about task/protected type,
4919 2017-09-07 Bob Duff <duff@adacore.com>
4921 * binde.adb (Debug_Flag_Old): If both -do and -dp

4932 * sem_prag.adb (Find_Role): The Global_Seen flag
4933 is now consulted not only for abstract states and variables,
4934 but for all kinds of items.
4935 (Collect_Subprogram_Inputs_Outputs): Do not process formal
4936 generic parameters, because unlike ordinary formal parameters,
4937 generic formals only act as input/ outputs if they are explicitly
4938 mentioned in a Global contract.
4940 2017-09-07 Yannick Moy <moy@adacore.com>
4942 * ghost.adb (Check_Ghost_Context): Do not err on ghost code inside
4943 predicate procedure. Check predicate pragma/aspect with Ghost entity.

4955 derived recor type, copy the dikensions if any of each component
4956 of the parent record to the corresponding component declarations
4957 of the derived record. These expressions are used among other
4958 things as default values in aggregates with box associations.

4970 also mark the renamed subprogram as referenced.
4972 2017-09-07 Ed Schonberg <schonberg@adacore.com>
4974 * par-ch6.adb (P_Subprogram): Improve error message on null
4975 procedure with misplaced aspect specification, which the parser
4976 first attempts to interpret as a malformed expression function.
4978 2017-09-07 Gary Dismukes <dismukes@adacore.com>

5003 Make_Build_In_Place_Call_In_Anonymous_Context): Do not use the
5004 secondary stack for all functions that return limited tagged
5005 types -- just do it for dispatching calls. Misc cleanup.
5006 * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
5007 remove qualifications and type conversions. Fix various bugs
5008 where only a single level of qualification or conversion was
5009 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
5011 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
5014 2017-09-07 Ed Schonberg <schonberg@adacore.com>
5016 * sem_ch6.adb (setr_Actual_Subtypes): Within a predicate function
5017 do not create actual subtypes that may generate further predicate
5019 * sem_ch13.adb (Build_Predicate_Functions): Indicate that entity
5020 of body is a predicate function as well.
5021 (Resolve_Aspect_Expressions, Resolve_Name): For a component
5022 association, only the expression needs resolution, not the name.
5023 (Resolve_Aspect_Expressions, case Predicates): Construct and
5024 analyze the predicate function declaration in the scope of the
5025 type, before making the type and its discriminants visible.
5027 2017-09-06 Eric Botcazou <ebotcazou@adacore.com>

5066 2017-09-06 Bob Duff <duff@adacore.com>
5068 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
5069 requested. Previously, the -do switch meant "run Elab_New and
5070 Elab_Old and use the order chosen by Elab_Old, possibly with
5071 debugging printouts comparing the two orders." Now it means
5072 "do not run Elab_New." This is of use if there are bugs that
5073 cause Elab_New to crash.
5074 (Elab_Position, Num_Chosen): Change type to Nat, to avoid various

5090 * freeze.adb (Freeze_Record_Type)
5091 <Sized_Component_Total_Round_RM_Size>: New local variable to
5092 accumulate the rounded RM_Size of components. Update it for
5093 every component whose RM_Size is statically known. Add missing
5094 guard to check that bit packing is really required before issuing
5095 the error about packing. Swap condition for clarity's sake.

5117 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5119 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
5120 entity of a mutable type and the right-hand side is a conditional
5121 expression, resolve the alternatives of the conditional using
5122 the base type of the target entity, because the alternatives
5123 may have distinct subtypes. This is particularly relevant if
5124 the alternatives are aggregates.
5126 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5128 * checks.adb (Apply_Predicate_Check): If the expression is an
5129 aggregate that is the RHS of an assignment, apply the check to
5130 the LHS after the assignment, rather than to the aggregate. This
5131 is more efficient than creating a temporary for the aggregate,
5132 and prevents back-end crashes when the aggregate includes a
5133 dynamic "others' association.

5153 2017-09-06 Gary Dismukes <dismukes@adacore.com>
5155 * errout.adb (Error_Msg): Separate the
5156 treatment for warning vs. style messages in inlinings and
5157 instantiations. Prevents blowups on calls to Warn_Insertion for
5158 style messages, which should not be called in that case because
5159 Warning_Msg_Char is not set.
5161 2017-09-06 Justin Squirek <squirek@adacore.com>

5164 to group all Volatile_Full_Access checks relating to other
5165 representation pragmas (Mark_Component_Or_Object): Created
5166 to centeralize the flagging of attributes for the record type
5167 component case, a pragma applied individually to a component, and

5186 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
5187 that is a proper body corresponding to a stub, we defer the
5188 adjustment of the sloc until after the correct adjustment has
5189 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
5190 the adjustment, because it will be outside the range in (the old,
5191 incorrect) S_Adjustment.
5192 * inline.adb: Use named notation for readability and uniformity.

5214 Linker_Section_Pragma.
5215 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
5216 checking for container loops so that the index cursor is not
5217 directly changable by the user with the use of E_Loop_Parameter.
5218 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.

5263 Generate a freeze node for the actual of a formal package, if
5264 the actual is declared in the same unit and has a corresponding
5265 body, to prevent the current instance from being frozen before

5292 (Strip): New routine.
5294 2017-09-06 Bob Duff <duff@adacore.com>
5296 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
5297 we include the proper header. Otherwise, we just declare the necessary
5298 things from the capabilities library. This is so we can build on
5299 machines without that library, while still enabling that library.
5300 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
5301 simply return 0 if the library is not present, or not included

5317 has no parameter specification and no entry index, use the entry name
5318 as the end of the generated SCO statement.
5320 2017-09-06 Steve Baird <baird@adacore.com>
5322 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
5323 uses of 'Image and related attributes as having side effects in
5324 order to avoid replicating such uses.
5325 * pprint.ads (Expression_Image) Add new generic formal flag
5326 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
5327 (eventually) override the default.
5328 * pprint.adb (Expression_Image) If the new flag is set, then
5329 suppress the ".all" suffix when displaying a dereference whose
5330 prefix is a use of a value-capturing compiler temp of the sort
5331 generated by Expr_Util.Remove_Side_Effects .

5389 2017-09-06 Yannick Moy <moy@adacore.com>
5391 * freeze.adb (Check_Inherited_Conditions): Rewriting
5392 of inherited preconditions and postconditions should only occur
5393 in GNATprove mode, that is, when GNATprove_Mode is True, not to
5394 be confused with SPARK_Mode being On.

5409 on the procedure created to encapsulate the body.
5410 * sem_ch7.adb: Add with clause for GNAT.HTable.
5411 (Entity_Table_Size): New constant.
5412 (Entity_Hash): New function.
5413 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
5414 (Is_Subprogram_Ref): Rename into...
5415 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
5416 the table instead of bailing out on them. Scan the value of constants
5417 if it is not known at compile time.
5418 (Contains_Subprograms_Refs): Rename into...
5419 (Scan_Subprogram_Refs): ...this.
5420 (Has_Referencer): Scan the body of all inlined subprograms. Reset the
5421 Is_Public flag on subprograms if they are not actually referenced.
5422 (Hide_Public_Entities): Beef up comment on the algorithm.
5423 Reset the table of subprograms on entry.

5536 that Ada.Command_Line contains modern Ada (the raise expression).
5537 * gnatbind.adb: Avoid dependence on
5538 Ada.Command_Line. Depend on System.Response_File instead

5680 left-hand side, which are invisible in the righ-hand side and
5681 not retrievable as selected components.
5683 2017-09-06 Ed Schonberg <schonberg@adacore.com>
5685 * sem_util.adb (Needs_One_Formal): The first formal of such a

5722 discriminants, the constraint for the target must obtain the
5723 discriminant values from both the operand and from the stored
5724 constraint for it, given that the constrained discriminants are
5725 not visible in the object.
5726 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
5727 side may be derived from that of the left-hand side (as in the
5728 case of an assignment with a change of representation) so the
5729 discriminant to be used in the retrieval of the value of the
5730 component must be the entity in the type of the right-hand side.

5759 in a set membership is an overloaded enumeration literal, and
5760 the type of the alternative is resolved from a previous one,
5761 replace the entity of the alternative as well as the type,
5762 to prevent inconsistencies between the entity and the type.

6305 * exp_ch6.adb (Expand_Call_Helper): When locating the
6306 accessibility entity created for an access parameter, handle
6307 properly a reference to a formal of an enclosing subprogram. if
6308 the reference appears in an inherited class-wide condition, it
6309 is the rewriting of the reference in the ancestor expression,
6310 but the accessibility entity must be that of the current formal.

6314 * exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.

6347 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6349 * exp_ch3.adb (Freeze_Type): Do not generate an invariant
6350 procedure body for a local (sub)type declaration within a
6351 predicate function. Invariant checks do not apply to these, and
6352 the expansion of the procedure will happen in the wrong scope,
6353 leading to misplaced freeze nodes.
6355 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6357 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
6358 to analyze generated actions. If the main unit is a body,

6363 * einfo.adb (Declaration_Node): flip branches of
6364 an IF statement to avoid repeated negations in its condition;

6394 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
6395 Refine predicate for the case where the primitive operation
6396 is a renaming of equality. An overriding operation that is
6397 a user-defined renaming of predefined equality inherits its
6398 slot from the overridden operation. Otherwise it is treated
6399 as a predefined op and occupies the same predefined slot as
6400 equality. A call to it is transformed into a call to its alias,
6401 which is the predefined equality. A dispatching call thus uses
6402 the proper slot if operation is further inherited and called
6403 with class-wide arguments.
6405 2017-05-02 Justin Squirek <squirek@adacore.com>
6407 * errout.adb (Set_Msg_Text): Add a case to switch the message

6441 statement if the initialization call is a null procedure, as
6442 can happen with a controlled type with no explicit Initialize
6443 procedure, or an array of such.

6445 controlled components that has a trivial Initialize procedure,
6446 insert declaration for finalization counter after object

6449 finalization block and attendant declarations if component has
6450 a trivial Initialize procedure.
6451 (Make_Init_Call): Do not generate a call if controlled type has
6452 a trivial Initialize procedure.

6487 * checks.adb (Null_Exclusion_Static_Checks):
6488 Call Compile_Time_Constraint_Error instead of
6489 Apply_Compile_Time_Constraint_Error in the component case. Also
6490 call that when Array_Comp is True, with an appropriate warning for
6491 the array component case. Only create an explicit initialization
6492 by null in the case of an object of a null-excluding access type
6493 (and no longer do that in the component case).
6494 * sem_ch3.adb (Check_Component): Add a Boolean parameter
6495 Array_Comp defaulted to False. Pass Empty for the Comp
6496 actual when calling Null_Exclusion_Static_Checks in the case
6497 where Comp_Decl matches Object_Decl, because we don't have a
6498 component in that case. In the case of an object or component
6499 of an array type, pass True for Array_Comp on the recursive call

6504 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
6505 compute the linux priority from the Ada priority. Call this everywhere
6506 required. In particular, the previous version was not doing this

6545 visibility rules for equality operators that apply within an
6546 instantiation apply within an inlined body.
6547 * sem_type.adb (Add_One_Interp): ditto.
6549 2017-05-02 Hristian Kirtchev <kirtchev@adacore.com>

6613 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
6615 2017-05-02 Bob Duff <duff@adacore.com>
6617 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
6618 to find primitive ops, instead of using an Identifier that will
6619 later be looked up. This is necessary because these ops are not
6620 necessarily visible at all places where we need to call them.
6621 * exp_util.ads: Minor comment fix.
6623 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6625 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
6626 references are fully conformant if they are both expansions
6627 of the discriminant of a protected type, within one of the
6628 protected operations. One occurrence may be expanded into a
6629 constant declaration while the other is an input parameter to
6630 the corresponding generated subprogram.

6660 array components specially.
6662 2017-05-02 Ed Schonberg <schonberg@adacore.com>
6664 * sem_ch8.adb (Premature_Usage): If the premature usage of
6665 an entity is as the expression in its own object decaration,
6666 rewrite the reference as Any_Id to prevent cascaded errors or
6667 compiler loops when such an entity is used in an address clause.
6669 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
6671 * gcc-interface/decl.c (components_to_record): Add missing guard.

6676 Put back pending fields onto the regular list if the misalignment
6677 happens to cancel itself.
6679 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6681 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
6682 controlling actual in a prefixed call, preserve the original node
6683 information if the prefix itself has been rewritten, for ASIS use.
6685 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6687 * exp_ch6.adb (Insert_Post_Call_Actions):
6688 Code clean up. Insert the post-call actions after an enclosing
6689 procedure call when N denotes a function call and appears as an
6690 actual parameter in the procedure call.
6692 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
6694 * freeze.adb (Check_Component_Storage_Order): If there is a clause
6695 for the component, also reject the attribute if the component
6696 doesn't end on a byte boundary and its scalar storage order is
6697 different from that of the enclosing record type.
6699 2017-04-28 Javier Miranda <miranda@adacore.com>
6701 * atree.ads (Info_Messages): Removed.

6733 * sem_util.ads, sem_util.adb (Might_Raise): New function
6734 that replaces Is_Exception_Safe, but has the opposite
6735 sense. Is_Exception_Safe was missing various cases -- calls inside
6736 a pragma Debug, calls inside an 'if' or assignment statement,
6737 etc. Might_Raise now walks the entire subtree looking for things
6739 * exp_ch9.adb (Is_Exception_Safe): Remove.
6740 (Build_Protected_Subprogram_Body): Replace call to
6741 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
6742 constants where possible).

6779 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6781 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
6782 that follows an expression function must not be relocated to
6783 the generated body, because it applies to the code that follows.
6785 2017-04-28 Gary Dismukes <dismukes@adacore.com>
6787 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
6788 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
6789 code that might violate the more stringent checking for 'Access
6790 introduced in Ada 2005.
6792 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6794 * a-cforse.adb: minor style fix in comment.
6796 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>

6819 2017-04-28 Bob Duff <duff@adacore.com>
6821 * alloc.ads (Nodes_Initial): Go back to previous value. The large
6822 value makes large compilations faster, but small compilations slower.
6824 2017-04-28 Arnaud Charlet <charlet@adacore.com>
6826 * sem_util.adb: minor typos in Is_Child_Or_Sibling.

6844 2017-04-28 Ed Schonberg <schonberg@adacore.com>
6846 * sem_res.adb (In_Instance_Code): New predicate in
6847 Valid_Conversion, to determine whether a type conversion appears
6848 as (or within) an actual for a formal object. Type conversions
6849 in instances are not rechecked in Valid_Conversion because
6850 visibility changes between generic location andi instance may
6851 lead to spurious errors, but conversions within an actual must be
6852 fully checked, and they are not fully resolved when pre-analyzing
6855 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
6857 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
6858 New_Copy_Tree instead of Relocate_Node as any subsequent copies
6859 of the relocated node will have mangled Parent pointers.
6860 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
6861 tables used in conjunction with entity and itype replication.
6862 (Visit_Entity): Rewrite the restriction on which entities

6905 parameters. Rename local variables and adjust recursive call.
6906 Rework final scan of the field list and implement warnings on the
6907 problematic placement of specific sorts of fields.

6952 * exp_util.adb (Replace_Entity): The prefix of a 'Result
6953 attribute reference in a post- condition is the subprogram to
6954 which the condition applies. If the condition is inherited
6955 by a type extension, the prefix becomes a reference to the
6956 inherited operation, but there is no need to create a wrapper

6971 * alloc.ads (Nodes_Initial): Use a much larger value, because
6972 the compiler was spending a lot of time copying the nodes table
6973 when it grows. This number was chosen in 1996, so is rather out
6974 of date with current memory sizes. Anyway, it's virtual memory.
6975 Get rid of Orig_Nodes_...; use Node_... instead.
6976 * atree.adb (Lock): Do not release the Nodes tables; it's a
6978 Orig_Nodes_ ==> Nodes_

7044 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
7045 prefix can be an object reference in which case Obj'Image (X)
7046 can only be interpreted as an indexing of the parameterless
7047 version of the attribute.
7048 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
7049 an indexing or a slice operation if the attribute does not require
7050 parameters. In Ada2012 'Image also belongs in this category,
7051 and A'Image (lo .. hi) is legal and must be parsed as a slice.

7712 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
7713 to manage the secondary stack when an enclosing scope already
7714 performs this functionality (aka relaxed management). Switch
7715 -gnatd.s may be used to force strict management in which case
7716 the block will manage the secondary stack unconditionally. Add
7717 a guard to stop the traversal when encountering a package or a

7722 * sem_res.adb (Resolve_Call): Refine further the handling of
7723 limited views of return types in function calls. If the function
7724 that returns a limited view appears in the current unit,

7726 this transformation is performed int the back-end. However,
7727 the type of the call itself must be the non-limited view, to
7728 prevent spurious resolution errors.

7732 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
7733 Removed, proposed implementation using generics for class-wide

7735 (Class_Wide_Clone): New attribute of subprogram. Designates
7736 subprogram created for primitive operations with class-wide
7737 pre/postconditions that contain calls to other primitives. The
7738 clone holds the body of the original primitive, but the
7739 pre/postonditions do not apply to it. The original body is
7740 rewritten as a wrapper for a call to the clone.
7741 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
7742 the flag is set, no code for the corresponding pre/postconditions
7743 is inserted into its body.

7815 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
7816 point type actual that has user-defined arithmetic primitives,
7817 when there is a previous actual for a formal package that defines
7818 a fixed-point type with the parent user-defined operator.

7834 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
7835 dimensions of operands if node has been analyzed already, because
7836 previous analysis and dimension checking will have removed the
7837 dimension information from the operands.

7841 * debug.adb: Document the use of switch -gnatd.s.

7924 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
7925 * sinput-p.adb: Use regular fat pointers, with bounds checking,
7926 for source buffers. Fix misc obscure bugs.
7927 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
7928 checking, for source buffers. Modify representation clause for
7929 Source_File_Record as appropriate. Move Source_File_Index_Table
7930 from spec to body, because it is not used outside the body.
7931 Move Set_Source_File_Index_Table into the private part, because
7932 it is used only in the body and in children. Use trickery to
7933 modify the dope in the generic instantiation case. It's ugly,
7934 but not as ugly as the previous method. Fix documentation.
7935 Remove obsolete code.

7951 expander is not active or when index/range checks are suppressed
7953 (Insert_List_After_And_Analyze, Insert_List_Before_And_Analyze):
7954 Remove variants that include a Supress parameter. These routines
7955 are never used, and were introduced before the current scope-based
7956 check suppression method.

8007 scn.ads, gnatls.adb: Eliminate the vestigial Internal_Source_File and
8008 the Internal_Source buffer. This removes the incorrect call to "="
8009 the customer noticed.
8010 Wrap remaining calls to "=" in Null_Source_Buffer_Ptr. We
8011 eventually need to eliminate them altogether. Or else get rid
8012 of zero-origin addressing.

8422 2017-04-25 Yannick Moy <moy@adacore.com>
8424 * sem_util.adb, sem_util.ads (Unique_Defining_Entity): Update
8425 comment to reflect which entity is chosen as unique entity.
8426 (Unique_Entity): Return full view instead of private spec for
8427 protected type or task type. Fix possible incorrect access when
8430 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8432 * sem_res.adb (Set_Slice_Subtype): Treat specially bit-packed
8433 array types only instead of all packed array types.
8435 2017-04-25 Ed Schonberg <schonberg@adacore.com>

8454 2017-04-25 Claire Dross <dross@adacore.com>
8456 * sem_prag.adb (Collect_Inherited_Class_Wide_Conditions): Go to
8457 ultimate alias when accessing overridden operation. Indeed, if the
8458 overridden operation is itself inherited, it won't have any explicit
8461 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8463 * sem_warn.adb (Warn_On_Overlapping_Actuals): There can be no
8464 overlap if the two formals have different types, because formally
8465 the corresponding actuals cannot designate the same objects.
8467 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8469 * sem_dim.adb (Dimensions_Of_Operand): minot cleanups: a) If
8470 dimensions are present from context, use them. b) If operand is
8471 a static constant rewritten as a literal, obtain the dimensions
8472 from the original declaration, otherwise use dimensions of type
8473 established from context.
8475 2017-04-25 Yannick Moy <moy@adacore.com>
8477 * sem_util.adb (Is_Effectively_Volatile): Protect against base type

8490 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8492 * sem_disp.adb (Check_Dispatching_Context): Add guard to refine
8493 the check that recognizes a call to a private overridding and
8494 replaces the called subprogram with its alias.
8496 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8498 * exp_util.adb: Minor reformatting.
8500 2017-04-25 Justin Squirek <squirek@adacore.com>
8502 * exp_ch3.adb (Freeze_Type): Add condition to always treat
8503 interface types as a partial view of a private type for the
8504 generation of invariant procedure bodies.
8505 * exp_util.adb, exp_util.ads (Add_Inherited_Invariants):
8506 Add a condition to get the Corresponding_Record_Type for
8507 concurrent types, add condition to return in the absence of a
8508 class in the pragma, remove call to Replace_Type_References,
8509 and add call to Replace_References.
8510 (Add_Interface_Invariatns),
8511 (Add_Parent_Invariants): Modify call to Add_Inherited_Invariants
8512 to including the working type T.
8513 (Add_Own_Invariants): Remove
8514 legacy condition for separate units, remove dispatching for ASIS
8515 and save a copy of the expression in the pragma expression.
8516 (Build_Invariant_Procedure_Body): Default initalize vars,
8517 remove return condition on interfaces, always use the
8518 private type for interfaces, and move the processing of types
8519 until after the processing of invariants for the full view.
8520 (Build_Invariant_Procedure_Declaration): Remove condition
8521 to return if an interface type is encountered and add
8522 condition to convert the formal parameter to its class-wide
8523 counterpart if Work_Typ is abstract.
8524 (Replace_Type): Add call to Remove_Controlling_Arguments.
8525 (Replace_Type_Ref): Remove class-wide dispatching for the current
8526 instance of the type.
8527 (Replace_Type_References): Remove parameter "Derived"
8528 (Remove_Controlling_Arguments): Created in order to removing
8529 the controlliong argument from calls to primitives in the case
8530 of the formal parameter being an class-wide abstract type.
8531 * sem_ch3.adb (Build_Assertion_Bodies_For_Type): Almost identical
8532 to the change made to Freeze_Type in exp_ch3. Add a condition
8533 to treat interface types as a partial view.
8534 * sem_prag.adb (Analyze_Pragma): Modify parameters in the call
8535 to Build_Invariant_Procedure_Declaration to properly generate a
8536 "partial" invariant procedure when Typ is an interface.

8540 * a-numeri.ads: Go back to using brackets encoding for the Greek
8543 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8545 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
8546 (10-15): if derived type T with progenitors is abstract,
8547 and primitive P of this type inherits non-trivial classwide
8548 preconditions from both a parent operation and from an interface
8549 operation, then the inherited operation is abstract if the parent
8550 operation is not null.
8551 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
8552 with Covered_Interface_Op to yield the actual interface operation
8553 that is implemented by a given inherited operation.
8555 2017-04-25 Javier Miranda <miranda@adacore.com>
8557 * exp_ch4.adb (Expand_N_Op_Expon): Relocate left
8558 and right operands after performing the validity checks. Required
8559 because validity checks may remove side effects from the operands.
8561 2017-04-25 Javier Miranda <miranda@adacore.com>
8563 * exp_attr.adb (Attribute_Unrestricted_Access):
8564 Do not disable implicit type conversion. Required to generate
8565 code that displaces the pointer to reference the secondary

8571 Required_Artifacts attribute.
8573 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8575 * sem_util.adb (Same_Value): String literals are compile-time
8576 values, and comparing them must use Expr_Value_S.
8578 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8580 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
8581 dereference is introduced for the object, and the object is
8582 overloaded, do not check whether it is aliased, because it may
8583 include an implicit dereference.
8584 * sem_type.adb (Disambiguate): If two interpretations are access
8585 attribute types with the same designated type keep either of
8586 them and do not report an ambiguity. A true ambiguity will be
8589 2017-04-25 Bob Duff <duff@adacore.com>
8591 * a-numeri.ads: Change the encoding of Greek letter Pi from
8592 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
8593 to indicate the encoding. We considered using a byte order mark
8594 (BOM), but that causes various trouble (misc software eats the
8595 BOM, if you have a patch with a BOM, then it's not at the start
8596 of the patch, so it's not a BOM, the BOM affects with-ing files,
8598 * scng.adb, s-wchcnv.adb: Minor.

8610 moved here from sem_ch3.
8611 * sem_ch8.adb (Analyze_Subprogram_Renaming): Implement legality
8612 check given in RM 6.1.1 (17) concerning renamings of overriding
8613 operations that inherits class-wide preconditions from ancestor

8639 * sem_ch3.adb (Has_Non_Trivial_Precondition): New predicate to
8640 enforce legality rule on classwide preconditions inherited from
8641 both an ancestor and a progenitor (RM 6.1.1 (10-13).
8642 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
8643 subprogram need not be dispatching if it appears in a precondition
8644 for an abstract or null subprogram.
8646 2017-04-25 Gary Dismukes <dismukes@adacore.com>
8648 * sem_ch10.adb: Minor typo fix.
8650 2017-04-25 Arnaud Charlet <charlet@adacore.com>
8652 * gcc-interface/Makefile.in: Cleanup VxWorks targets.
8654 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>

8657 have a length which is a power of 2.
8658 (Is_Predefined_File_Name): Likewise. Adjust comment.
8660 2017-04-25 Bob Duff <duff@adacore.com>
8662 * exp_aggr.adb (Component_Count): Protect the
8663 arithmetic from attempting to convert a value >= 2**31 to Int,
8664 which would otherwise raise Constraint_Error.
8666 2017-04-25 Bob Duff <duff@adacore.com>
8668 * opt.ads (Locking_Policy): Fix incorrect documentation. The
8669 first character of the policy name is not unique.
8671 2017-04-25 Bob Duff <duff@adacore.com>
8673 * s-fileio.adb (Name): Raise Use_Error if the file is a temp file.
8674 * s-ficobl.ads (Is_Temporary_File): Remove incorrect comment
8675 about this flag not being used. It was already used, and it is

8692 Save and restore the value of global flag
8693 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value
8694 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance when either
8695 the corresponding spec or the body must ignore all SPARK_Mode
8696 pragmas found within.
8697 (Analyze_Subprogram_Declaration): Mark
8698 the spec when it needs to ignore all SPARK_Mode pragmas found
8699 within to allow the body to infer this property in case it is
8700 instantiated or inlined later.
8701 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
8702 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
8703 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
8704 when the corresponding spec also ignored all SPARK_Mode pragmas
8706 (Analyze_Package_Declaration): Mark the spec when
8707 it needs to ignore all SPARK_Mode pragmas found within to allow
8708 the body to infer this property in case it is instantiated or
8710 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
8711 Save and restore the value of flag
8712 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
8713 formal spec when it needs to ignore all SPARK_Mode
8714 pragmas found within to allow the body to infer this
8715 property in case it is instantiated or inlined later.
8716 (Analyze_Package_Instantiation): Save and restore the value
8717 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
8718 the instance spec when it needs to ignore all SPARK_Mode

8722 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
8723 instance spec and anonymous package when they need to ignore
8724 all SPARK_Mode pragmas found within to allow the body to infer
8725 this property in case it is instantiated or inlined later.
8726 (Instantiate_Package_Body): Save and restore the value of global
8727 flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set the value of

8737 Ignore_Pragma_SPARK_Mode.
8738 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
8739 all SPARK_Mode pragmas defined within yields mode "off".
8741 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8743 * bindgen.adb, exp_dbug.adb, errout.adb, fname.adb: Minor reformatting.

8758 * s-taprop-linux.adb: Minor editorial fixes.
8760 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8762 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
8763 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
8764 variable and set it to True whenever the main hash table is
8765 populated. Short- circuit the Assoc function if it is false
8766 and add associated guards.
8768 2017-04-25 Olivier Hainque <hainque@adacore.com>
8770 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
8771 specs without elaboration code that have an elaboration counter
8772 nevertheless, e.g. when compiled with -fpreserve-control-flow.
8773 * sem_ch10.adb (Analyze_Compilation_Unit):
8774 Set_Elaboration_Entity_Required when requested to preserve
8775 control flow, to ensure the unit elaboration is materialized at
8776 bind time, resulting in the inclusion of the unit object file
8777 in the executable closure at link time.
8779 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
8781 * exp_dbug.adb: In Debug_Renaming_Declaration,
8782 when dealing with indexed component, accept to produce a renaming
8783 symbol when the index is an IN parameter or when it is a name
8784 defined in an outer scope.
8786 2017-04-25 Yannick Moy <moy@adacore.com>
8788 * errout.adb (Error_Msg): Adapt continuation
8789 message in instantiations and inlined bodies for info messages.
8791 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
8793 * fname.adb (Has_Internal_Extension): Add pragma Inline.
8794 Use direct 4-character slice comparisons.
8796 pragma Inline. (Has_Suffix): Delete.
8797 (Is_Internal_File_Name):
8798 Test Is_Predefined_File_Name first.
8799 (Is_Predefined_File_Name):

8803 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8805 * checks.adb (Insert_Valid_Check): Code cleanup.
8806 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
8807 (Expand_Actuals): Generate proper copy-back for a validation
8808 variable when it acts as the argument of a type conversion.
8809 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
8810 predicate to operate on type qualifications.
8812 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8814 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
8817 2017-04-25 Bob Duff <duff@adacore.com>
8819 * sem_prag.adb (No_Return): Give an error if the pragma applies
8820 to a body. Specialize the error for the specless body case,
8821 as is done for (e.g.) pragma Convention.
8822 * debug.adb: Add switch -gnatd.J to disable the above legality
8823 checks. This is mainly for use in our test suite, to avoid
8824 rewriting a lot of illegal (but working) code. It might also
8825 be useful to customers. Under this switch, if a pragma No_Return
8826 applies to a body, and the procedure raises an exception (as it
8827 should), the pragma has no effect. If the procedure does return,
8828 execution is erroneous.
8830 2017-04-25 Bob Duff <duff@adacore.com>
8832 * exp_ch6.adb (Expand_Actuals): This is the
8833 root of the problem. It took N as an 'in out' parameter, and in
8834 some cases, rewrote N, but then set N to Original_Node(N). So
8835 the node returned in N had no Parent. The caller continued
8836 processing of this orphaned node. In some cases that caused a
8837 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
8838 and trips over the Empty Parent). The solution is to make N an
8839 'in' parameter. Instead of rewriting it, return the list of
8840 post-call actions, so the caller can do the rewriting later,
8841 after N has been fully processed.
8842 (Expand_Call_Helper): Move most of Expand_Call here. It has
8843 too many premature 'return' statements, and we want to do the
8844 rewriting on return.
8845 (Insert_Post_Call_Actions): New procedure to insert the post-call
8846 actions in the appropriate place. In the problematic case,
8847 that involves rewriting N as an Expression_With_Actions.
8848 (Expand_Call): Call the new procedures Expand_Call_Helper and
8849 Insert_Post_Call_Actions.
8851 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8853 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
8854 properly type derived from generic formal types, to handle
8855 properly modified version of ACATS 4.1B B611017.
8857 2017-04-25 Javier Miranda <miranda@adacore.com>
8859 * exp_unst.adb (Subp_Index): Adding missing
8860 support for renamings and functions that return a constrained
8861 array type (i.e. functions for which the frontend built a
8862 procedure with an extra out parameter).
8864 2017-04-25 Pascal Obry <obry@adacore.com>
8866 * s-string.adb: Minor code clean-up.
8868 2017-04-25 Bob Duff <duff@adacore.com>

8875 2017-04-25 Bob Duff <duff@adacore.com>
8877 * prep.adb (Preprocess): Remove incorrect
8878 Assert. Current character can be ASCII.CR.
8880 2017-04-25 Ed Schonberg <schonberg@adacore.com>
8882 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
8883 convention Stdcall, which has a number of exceptions. Convention
8884 is legal on a component declaration whose type is an anonymous
8885 access to subprogram.
8887 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8889 * sem_ch4.adb: sem_ch4.adb Various reformattings.
8890 (Try_One_Prefix_Interpretation): Use the base type when dealing
8891 with a subtype created for purposes of constraining a private
8892 type with discriminants.
8894 2017-04-25 Javier Miranda <miranda@adacore.com>
8896 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.

8898 dispatching primitives (Restore_Warnings): Restore warning on
8899 late dispatching primitives (Save_Warnings): Save warning on late
8900 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
8901 to enable/disable this warning.
8902 (WA_Warnings): Set warning on late dispatching primitives.
8903 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
8904 that its parent type has a private extension.
8905 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
8907 * usage.adb: Document -gnatw.j and -gnatw.J.
8909 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8911 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
8914 2017-04-25 Bob Duff <duff@adacore.com>
8916 * binde.adb (Validate): Do not pass dynamic strings
8917 to pragma Assert, because older compilers do not support that.
8919 2017-04-25 Bob Duff <duff@adacore.com>
8921 * s-fileio.adb (Close): When a temp file is
8922 closed, delete it and clean up its Temp_File_Record immediately,
8923 rather than waiting until later.
8924 (Temp_File_Record): Add File
8925 component, so Close can know which Temp_File_Record corresponds
8926 to the file being closed.
8927 (Delete): Don't delete temp files,
8928 because they are deleted by Close.
8929 (Open): Set the File component
8930 of Temp_File_Record. This requires moving the creation of the
8931 Temp_File_Record to the end, after the AFCB has been created.
8933 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
8935 * checks.adb (Insert_Valid_Check): Do not generate

8960 conversions from float to integer in GNATprove mode.
8961 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
8962 to call Apply_Type_Conversion_Checks, so that range checks
8963 are properly positioned when needed on conversions, including
8964 when converting from float to integer. (Determine_Range): In
8965 GNATprove mode, take into account the possibility of conversion
8966 from float to integer.
8967 * sem_res.adb (Resolve_Type_Conversion): Only enforce range
8968 check on conversions from fixed-point to integer, not anymore
8969 on conversions from floating-point to integer, when in GNATprove
8972 2017-04-25 Yannick Moy <moy@adacore.com>
8974 * checks.adb (Determine_Range_R): Special case type conversions
8975 from integer to float in order to get bounds in that case too.
8976 * eval_fat.adb (Machine): Avoid issuing warnings in GNATprove
8977 mode, for computations involved in interval checking.

8991 * exp_attr.adb (Make_Range_Test): Add processing for validation
8992 variables to avoid extra reads and copies of the prefix.
8993 * exp_ch6.adb (Expand_Actuals): Add copy-back for validation
8994 variables in order to reflect any changes done in the variable
8995 back into the original object.
8996 * sem_util.adb (Is_Validation_Variable_Reference): New routine.
8997 * sem_util.ads (Is_Validation_Variable_Reference): New routine.

9011 Pre'Class aspect is specified for the corresponding primitive
9012 subprogram of some ancestor of T.
9014 2017-04-25 Bob Duff <duff@adacore.com>
9016 * sem_ch8.adb (Use_One_Type): If a use_type_clause
9017 is redundant, set its Used_Operations to empty. This is only
9018 necessary for use clauses that appear in the parent of a generic
9019 child unit, because those use clauses get reanalyzed when we
9020 instantiate the generic, and we don't want the Used_Operations
9021 carried over from the original context (where it was probably

9037 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9039 * sem_ch8.adb (Find_Type): For an attribute reference
9040 'Class, if prefix type is synchronized and previous errors
9041 have suppressed the creation of the corresponding record type,
9042 create a spurious class-wide for the synchonized type itself,
9043 to catch other misuses of the attribute
9045 2017-04-25 Steve Baird <baird@adacore.com>
9047 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
9048 is True, then don't generate the accessibility check for the
9049 tag of a tagged result.

9051 if CodePeer_Mode is True, then don't generate the
9052 tag checks for the result of call to an instance of
9053 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
9054 descendant of" check and the accessibility check).
9056 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9058 * sem_ch13.adb: Code cleanups.
9059 * a-strbou.ads: minor whitespace fix in Trim for bounded strings.

9065 (Expand_Concatenate): When optimization is enabled, also expand
9066 the operation out-of-line if the concatenation is present within
9067 the expression of the declaration of a library-level object and
9068 not only if it is the expression of the declaration.
9070 2017-04-25 Bob Duff <duff@adacore.com>
9072 * freeze.adb (Freeze_Object_Declaration): Do
9073 not Remove_Side_Effects if there is a pragma Linker_Section,
9074 because in that case we want static initialization in the
9075 appropriate section.
9077 2017-04-25 Gary Dismukes <dismukes@adacore.com>
9079 * exp_dbug.adb: Minor rewording and reformatting.
9081 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9083 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
9084 handle the proposed changes to rules concerning potentially
9085 unevaluated expressions, to include selected components that
9086 do not depend on discriminants, and indexed components with
9088 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
9089 predicate in quantified expression, and fix bugs in the handling
9090 of case expressions and membership test.
9091 (Analyze_Attribute_Old_Result): use new predicate.

9108 renaming entity for debug information, mark the entity as needing debug
9109 info if it comes from sources.
9111 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9113 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the
9114 restriction converning the use of 'Address where the prefix is

9132 * sem_util.adb (Check_Internal_Protected_Use): Reject properly
9133 internal calls that appear in preconditions of protected
9134 operations, in default values for same, and in contract guards
9135 for contract cases in SPARK.

9146 * a-numaux-x86.ads: Fix package description.
9147 * a-numaux-x86.adb (Is_Nan): Minor tweak.
9148 (Reduce): Adjust and complete description. Call Is_Nan instead of
9149 testing manually. Use an integer temporary to hold rounded value.
9150 * a-numaux-darwin.adb (Reduce): Likewise.
9151 (Is_Nan): New function.
9153 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9155 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
9156 on analysis of prefix whose type is a current instance of a
9157 synchronized type, but where the prefix itself is an entity that

9162 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
9163 the identity of callable entities therein, because they have been
9164 properly resolved, and prefixed calls may have been rewritten
9167 2017-04-25 Patrick Bernardi <bernardi@adacore.com>
9169 * exp_ch3.adb (Build_Init_Statements): Convert
9170 the expression of the pragma/aspect Secondary_Stack_Size to

9183 * s-osinte-freebsd.ads: Minor comment tweaks
9185 2017-04-25 Javier Miranda <miranda@adacore.com>
9187 * urealp.adb (UR_Write): Reverse previous patch
9188 adding documentation on why we generate multiplications instead
9189 of divisions (needed to avoid expressions whose computation with
9190 large numbers may cause division by 0).
9192 2017-04-25 Bob Duff <duff@adacore.com>
9194 * erroutc.adb (Set_Specific_Warning_Off,
9195 Set_Warnings_Mode_Off): Use the correct source file for
9196 Stop. Was using Current_Source_File, which is only valid during
9197 parsing. Current_Source_File will have a leftover value from
9198 whatever file happened to be parsed last, because of a with_clause
9201 2017-04-25 Bob Duff <duff@adacore.com>
9203 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
9204 to In_Predefined_Unit, but including GNAT units.
9205 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
9206 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
9207 because Should_Ignore_Pragma was not working reliably outside
9208 the parser, because Current_Source_File is not valid.
9209 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
9210 * par-prag.adb: Call Should_Ignore_Pragma_Par.

9274 (Uses_Unseen_Lib_Unit_Priv): Predicate function made from extracted
9277 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9279 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
9280 of prefix whose type is a current instance of a synchronized
9281 type. If the prefix is an object this is an external call (or
9282 requeue) that can only access public operations of the object. The
9283 previous predicate was too restrictive, and did not allow public
9284 protected operations, only task entries.
9286 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9288 * sem_ch5.adb, fname.adb: Minor reformatting.
9290 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

9293 * einfo.ads Update the placement of
9294 E_Anonymous_Access_Subprogram_Type along with all subtypes that
9296 (Is_Anonymous_Access_Type): New routine.
9297 * exp_ch7.adb (Allows_Finalization_Master): Do not generate a
9298 master for an access type subject to pragma No_Heap_Finalization.
9299 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
9300 allocated or deallocated does not finalization actions if the
9301 associated access type is subject to pragma No_Heap_Finalization.
9302 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
9303 * par-prag.adb Pragma No_Heap_Finalization does not need special
9304 processing from the parser.
9305 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
9306 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
9307 * sem_prag.adb Add an entry in table Sig_Flags for pragma
9308 No_Heap_Finalization.
9309 (Analyze_Pragma): Add processing for

9314 and corresponding pragma id.
9316 2017-04-25 Bob Duff <duff@adacore.com>
9318 * freeze.adb (Freeze_Record_Type): Use the
9319 underlying type of the component type to determine whether it's
9320 elementary. For representation clause purposes, a private type
9321 should behave the same as its full type.
9322 * fname.ads, fname.adb (Is_Predefined_File_Name):
9323 Make sure things like "system.ali" are recognized as predefined.
9325 2017-04-25 Javier Miranda <miranda@adacore.com>
9327 * debug.adb: Update documentation of -gnatd.6.
9329 2017-04-25 Ed Schonberg <schonberg@adacore.com>
9331 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
9332 element iterator when the name is an overloaded function call,
9333 one of whose interpretations yields an array.
9335 2017-04-25 Bob Duff <duff@adacore.com>
9337 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
9338 Is_Internal_Unit_Name): New functions for operating on unit
9339 names, as opposed to file names. There's some duplicated code
9340 with fname.adb, which is unfortunate, but it seems like we don't
9341 want to add dependencies here.
9342 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
9343 to Is_Predefined_Unit_Name; the former was wrong, because Uname
9344 is not a file name at all.
9345 * fname.ads, fname.adb: Document the fact that
9346 Is_Predefined_File_Name and Is_Internal_File_Name can be called
9347 for ALI files, and fix the code so it works properly for ALI
9348 files. E.g. these should return True for "system.ali".
9350 2017-04-25 Justin Squirek <squirek@adacore.com>
9352 * exp_util.adb (Add_Invariant): Removed,
9353 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
9354 and Add_Own_Invariant. (Add_Invariant_Check): Used
9355 for adding runtime checks from any kind of invariant.
9356 (Add_Inherited_Invariant): Generates invariant checks for
9357 class-wide invariants (Add_Interface_Invariants): Removed, code
9358 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
9359 Create a types own invariant procedure (Add_Parent_Invariants):
9360 Removed, code moved to Build_Invariant_Procedure_Body
9361 (Build_Invariant_Procedure_Body): Add refactored calls
9362 and integrated code from Add_Parent_Invariants and
9363 Add_Interface_Invariants.
9364 (Process_Type): Removed, the
9365 relavant code was inlined into both Add_Own_Invariant and
9366 Add_Inherited_Invariant.
9368 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
9370 * make.adb, par-ch2.adb, sem_util.adb, scans.ads, sem_ch8.adb,

9387 and Build_Invariant_Procedure_Declaration.
9388 * exp_util.ads, exp_util.adb Add Build_Invariant_Procedure_Body
9389 and Build_Invariant_Procedure_Declaration from exp_ch7
9390 and break-out Is_Untagged_Private_Derivation from
9391 Build_Invariant_Procedure_Body.
9392 (Replace_Type_References):
9393 Append an extra parameter to allow for dispatching replacements
9394 and add the corrasponding logic.
9395 (Type_Invariant): Remove
9396 Replace_Typ_Refs and replace its references with calls to
9397 Replace_Type_References.
9398 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
9400 2017-04-25 Bob Duff <duff@adacore.com>
9402 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): New function
9403 that returns True when appropriate.
9404 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
9405 when compiling predefined files.
9406 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
9407 "gnat.adc" should not be considered a predefined file name.
9408 That required (or at least encouraged) a lot of cleanup of global
9409 variable usage. We shouldn't be communicating information via
9410 the global name buffer.
9411 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
9412 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

9426 * types.ads: Minor: Fix '???' comment.
9427 * sem_ch8.adb: Minor comment fix.
9429 2017-04-25 Bob Duff <duff@adacore.com>
9431 * sem_prag.adb: Remove suspicious uses of Name_Buf.
9432 * stringt.ads, stringt.adb, exp_dbug.adb, sem_dim.adb: Remove

10282 to the expected type with the appropriate check flags set.
10283 * sem_res.adb (Resolve_Range): The higher bound can be in Typ's
10284 base type if the range is null. It may still be invalid if it
10285 is higher than the lower bound. This is checked later in the
10286 context in which the range appears.

10301 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
10302 an object declaration for an array type with a modular index type
10303 with the size of Long_Long_Integer. Special processing is needed
10304 in this case to compute reliably the size of the object, and
10305 eventually to raise Storage_Error, when wrap-around arithmetic
10306 might compute a meangingless size for the object.
10308 2017-01-23 Justin Squirek <squirek@adacore.com>

10316 it is deciding whether to turn the call into an indexed
10317 component, avoid doing so if the call is to an instance of
10318 Unchecked_Conversion. Otherwise, the compiler turns it into an
10319 indexed component, and resolution of that turns it back into a
10320 function call, and so on, resulting in infinite recursion.
10321 * sem_util.adb (Needs_One_Actual): If the first formal has a
10322 default, then return False.

10367 2017-01-20 Ed Schonberg <schonberg@adacore.com>
10369 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
10370 must be treated as delayed aspect even if the expression is
10371 a literal, because the aspect affects the freezing and the
10372 elaboration of the object to which it applies.

10919 * scil_ll.adb: Minor style fix in comment.
10920 * sem_ch8.adb (Analyze_Expanded_Name): Perform dimension analysis
10921 even if entity is already set, because the node may be renalyzed
10922 after inlining transformations.
10924 2017-01-13 Javier Miranda <miranda@adacore.com>
10926 * sem_res.adb (Resolve_Call): Do not establish a transient scope
10927 for a call to inlinable expression function (since the call will
10928 be replaced by its returned object).
10929 * exp_ch6.ads (Is_Inlinable_Expression_Function): New subprogram.
10930 * exp_ch6.adb (Expression_Of_Expression_Function): New subprogram.
10931 (Expand_Call): For inlinable expression function call replace the

10947 (Get_Contract_Only_Missing_Body_Name): Removed.
10949 2017-01-13 Javier Miranda <miranda@adacore.com>
10951 * sem_ch6.adb (Cloned_Expression): New subprogram.
10952 (Freeze_Expr_Types): Complete previous patch since the expression
10953 of an expression-function may have iterators and loops with
10954 defining identifiers which, as part of the preanalysis of the
10955 expression, may be left decorated with itypes that will not be
10956 available in the tree passed to the backend.
10958 2017-01-13 Ed Schonberg <schonberg@adacore.com>
10960 * checks.adb (Apply_Type_Conversion_Checks): Optimize a type
10961 conversion to Integer of an expression that is an attribute
10962 reference 'Pos on an enumeration type.
10964 2017-01-13 Bob Duff <duff@adacore.com>
10966 * atree.ads: Minor comment fix.

10971 calls in accessibility check on return statement.
10973 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
10975 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
10976 Ensure that the input body is a subprogram body before trying to
10977 determine whether it denoted an expression function. Note that
10978 subprogram body stubs cannot denote expression functions.
10980 2017-01-13 Gary Dismukes <dismukes@adacore.com>
10982 * bindgen.adb, sem_ch6.adb, binde.adb, exp_ch3.adb: Minor reformatting
10985 2017-01-13 Javier Miranda <miranda@adacore.com>
10987 * einfo.ads (Component_Bit_Offset): Fix documentation.
10988 * sem_ch13.adb (Check_Record_Representation_Clause): Skip check
10989 on record holes for components with unknown compile-time offsets.
10991 2017-01-13 Bob Duff <duff@adacore.com>
10993 * ali.ads, ali.adb (Static_Elaboration_Model_Used): Remove unused flag.
10994 * g-locfil.ads: Minor comment fix.
10996 2017-01-13 Bob Duff <duff@adacore.com>
10998 * binde.adb (Elab_New): New elaboration order algorithm
10999 that is expected to cause fewer ABE issues. This is a work in
11000 progress. The new algorithm is currently disabled, and can be
11001 enable by the -dp switch, or by modifying the Do_Old and Do_New
11002 etc. flags and rebuilding. Experimental code is included to
11003 compare the results of the old and new algorithms.
11004 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
11005 can have multiple of these tables, so the old and new algorithms
11007 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
11008 parameter of type array. This avoids the global variable, and
11009 allows bounds checking (which is normally defeated by the tables
11010 packages). It also ensures that the Elab_Order is read-only
11012 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
11013 subprograms that need it, as above.
11014 * debug.adb: Document new -dp switch. Modify doc of old -do
11016 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
11017 and Bindgen. Move writing of closure (-R and -Ra switches)
11018 to Binde; that's more convenient.
11020 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11022 * sem_ch6.adb (Analyze_Expression_Function): If the expression
11023 function is a completion, all entities referenced in the
11024 expression are frozen. As a consequence, a reference to an
11025 uncompleted private type from an enclosing scope is illegal.
11027 2017-01-13 Javier Miranda <miranda@adacore.com>
11029 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
11030 (Analyze_Subprogram_Body_Helper): At the occurrence of an
11031 expression function declaration that is a completion, its
11032 expression causes freezing (AI12-0103).
11034 2017-01-13 Vadim Godunko <godunko@adacore.com>
11036 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and
11037 Reference functions of Ada.Containers.Indefinite_Holders.

11041 * s-os_lib.ads: Minor comment fixes.
11043 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11045 * exp_ch3.adb (Default_Initialize_Object): Do not default
11046 initialize an object when it is of a task type and restriction
11047 No_Tasking is in effect because the initialization is obsolete.
11048 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
11049 restriction No_Tasking is in effect.
11050 (Build_Master_Renaming): Do not rename a master when restriction
11051 No_Tasking is in effect.
11053 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11055 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
11056 the legality of An others clause applies as well to a choice in
11057 an Iterated_component_ association.
11058 (Resolve_Iterated_Component_Association): An others choice
11060 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
11061 Iterated_Component_Association is not static.
11063 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11065 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
11066 control is passed to the expresion handler before the new mode
11068 * sem_ch12.adb (Analyze_Package_Instantiation,
11069 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set
11070 in case control is passed to the expresion handler before the
11073 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
11075 * sem_aggr.adb, sem_ch3.adb, inline.adb, sem_util.adb, exp_ch4.adb,
11076 exp_aggr.adb: Minor reformatting.
11078 2017-01-13 Gary Dismukes <dismukes@adacore.com>
11080 * inline.adb: Minor reformatting and typo fix.
11082 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11084 * sem_util.ads, sem_util.adb (Choice_List): Move function here
11085 from sem_aggr.adb, for use elsewhere.
11086 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
11087 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
11088 Iterated_Component_Present.
11089 * exp_aggr.adb: Use Choice_List throughout, to handle
11090 Iterated_Component_Associations.
11091 (Gen_Loop): Generate proper loop for an
11092 Iterated_Component_Association: loop variable has the identifier
11093 of the original association. Generate a loop even for a single
11094 component choice, in order to make loop parameter visible in
11096 (Flatten): An Iterated_Component_Association is not static.
11098 2017-01-13 Yannick Moy <moy@adacore.com>
11100 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
11101 float exponentiation for statically known small negative values
11102 is the reciprocal of the exponentiation for the opposite value
11104 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
11105 Ensure that the value of float exponentiation for negative values
11106 is the reciprocal of the exponentiation for the opposite value
11108 * inline.adb (Expand_Inlined_Call): Fix the count
11109 for the number of generated gotos.
11111 2017-01-13 Yannick Moy <moy@adacore.com>

11114 * sem_util.adb (Is_OK_Volatile_Context): Add
11115 expression in delay statement as OK for volatile context.
11117 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11119 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
11120 mode a choice that is a subtype with a static predicate is
11121 replaced by the values it covers. This transformation must not
11122 be performed in ASIS mode, to preserve the source for analysis.
11124 2017-01-13 Justin Squirek <squirek@adacore.com>
11126 * nlists.ads: Correct minor typo.
11128 2017-01-13 Gary Dismukes <dismukes@adacore.com>
11130 * sem_ch13.adb: Minor reformatting and typo fix.
11132 2017-01-13 Ed Schonberg <schonberg@adacore.com>
11134 * par-ch4.adb (P_Aggregate_Or_Parent_Expr): An
11135 Iterated_Component_Association is a named association in an
11137 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
11138 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
11139 and resolve the discrete choices and the expression of the
11141 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
11142 Loop_Actions and Box_Present are attributes of
11143 N_Iterated_Component_Association nodes. Box_Present is always
11144 False in this case.
11145 * sprint.adb (Sprint_Node): An Iterated_Component_Association
11146 has a Discrete_Choices list, as specified in the RM. A
11147 Component_Association for aggregate uses instead a Choices list.
11148 We have to live with this small inconsistency because the new
11149 construct also has a defining identifier, and there is no way
11150 to merge the two node structures.
11152 2017-01-13 Yannick Moy <moy@adacore.com>
11154 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the

11161 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
11162 Analyze_Declarations, to analyze and resolve the expressions of
11163 aspect specifications in the current declarative list, so that
11164 the expressions have proper entity and type info. This is needed
11165 for ASIS when there is no subsequent expansion to generate this
11166 semantic information.
11167 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
11168 original expression, to suppress cascaded errors when expression
11169 has been constant-folded.
11170 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
11171 ASIS mode, because there is no subsequent expansion to decorate
11174 2017-01-13 Yannick Moy <moy@adacore.com>
11176 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
11177 New function to detect when a call may be inlined or not in
11179 (Expand_Inlined_Call): Ensure that a temporary
11180 is always created in the cases where a type conversion may be
11181 needed on an input parameter in GNATprove mode, so that GNATprove
11182 sees the check to perform.
11183 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
11184 when not applicable due to actual requiring type conversion
11185 with possible check but no temporary value can be copied for
11186 GNATprove to see the check.

11284 a function call that is the expansion of a string comparison.The
11285 function call is built when compiling the corresponding predicate
11286 function, but the expression has been found legal as a static
11287 predicate during earlier analysis.
11288 * sem_eval.adb (Real_Or_String_Static_Predicate_Matches): Handle
