410 to libgnat subdirectory.
412 2017-09-08 Yannick Moy <moy@adacore.com>
414 * sem_aux.adb, sem_aux.ads (Get_Called_Entity): New function to
415 return the entity associated with the call.
416 * sem_util.adb, sem_util.ads (Check_Function_Writable_Actuals):
417 Replace the internal Get_Function_Id with the new
418 Sem_Aux.Get_Called_Entity.
419 (Iterate_Call_Parameters): New
420 procedure to iterate on formals and actuals at the same time.
421 * sem_ch12.adb (Analyze_Subprogram_Instantiation):
422 Set SPARK_Mode from spec when set, for analysis
423 of instance. Restore after analysis of instance.
424 (Instantiate_Subprogram_Body): Set SPARK_Mode from body when
425 set, for analysis of body instance. Restored automatically at
426 the end of the subprogram.
427 * gnat1drv.adb (Adjust_Global_Switches): Set
428 Check_Validity_Of_Parameters to False in GNATprove mode.
429 * opt.ads (Check_Validity_Of_Parameters): Document switch to
432 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
434 * sem_util.adb (NCT_Tables_In_Use): Move to library level from...
435 (New_Copy_Tree): ...there. Reset the hash tables only if they
436 were used in the previous invocation.
437 * s-htable.adb: Fix typo.
439 2017-09-08 Bob Duff <duff@adacore.com>
441 * a-ssicst.adb (Open): Set File.Last_Op to the appropriate value.
443 2017-09-08 Arnaud Charlet <charlet@adacore.com>

447 2017-09-08 Bob Duff <duff@adacore.com>
449 * sprint.adb (Write_Corresponding_Source): Ignore if there is
450 no current source file.
451 (Write_Name_With_Col_Check, Write_Name_With_Col_Check_Sloc):
452 Print something helpful in case N is invalid.
453 * sprint.ads: Minor comment fix.
455 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
457 * exp_aggr.adb: (Aggr_Assignment_OK_For_Backend): Add early return for
460 2017-09-08 Bob Duff <duff@adacore.com>
462 * par-prag.adb, sem_prag.adb, snames.ads-tmpl: Implement pragma
463 Ada_2020, along the same lines as the other Ada version pragmas.
465 2017-09-08 Gary Dismukes <dismukes@adacore.com>
467 * sem_ch12.adb: Minor typo fixes and reformatting.
469 2017-09-08 Yannick Moy <moy@adacore.com>
471 * sem_aggr.adb (Resolve_Record_Aggregate):
472 Rewrite bounds of aggregate subexpressions which may depend on
473 discriminants of the enclosing aggregate.
475 2017-09-08 Yannick Moy <moy@adacore.com>
477 * sem_ch5.adb: Prevent assertion failure on illegal code.
479 2017-09-08 Yannick Moy <moy@adacore.com>
481 * lib-xref-spark_specific.adb (Add_SPARK_Xrefs.Is_SPARK_Scope): Avoid
482 calling Renamed_Entity on an entity which cannot be a renaming.
484 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
486 * exp_aggr.adb: Add with & use clause for Urealp.
487 (Aggr_Assignment_OK_For_Backend): Accept (almost all)
488 elementary types instead of just discrete types.
489 * sem_eval.adb (Expr_Value): Deal with N_Null for access types.
490 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>:
491 Be prepared for the FP zero value in the memset case. Add small
494 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
496 * s-htable.adb (Static_HTable.Reset): Use aggregate instead
499 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
501 * exp_aggr.adb (Expand_Array_Aggregate): Use New_Copy_Tree instead
502 of New_Copy because the latter leaves the syntactic structure of
503 the tree inconsistent (a child is accessible through two parents)
504 and prevents proper replication of itypes by subsequent calls
506 * exp_ch4.adb (Expand_Concatenate): Use New_Copy_Tree instead of
507 New_Copy because the latter leaves the syntactic structure of the
508 tree inconsistent (a child is accessible through two parents)
509 and prevents proper replication of itypes by subsequent calls
511 * sem_util.adb (In_Subtree): New routine.
512 (New_Copy_Tree): Reimplemented.
513 * sem_util.ads (In_Subtree): New routine.

516 2017-09-08 Ed Schonberg <schonberg@adacore.com>
518 * sem_ch13.adb (Resolve_Aspect_Expressions): The expression
519 for aspect Default_Value is a static scalar value, but it does
520 not freeze the type. Yhis allows for subsequent representation
521 clauses for the type.
523 2017-09-08 Javier Miranda <miranda@adacore.com>
525 * sem_ch8.adb (Find_Direct_Name.Undefined): Do
526 not add entries into the undefined reference table when we are
527 compiling with errors ignored.
529 2017-09-08 Ed Schonberg <schonberg@adacore.com>
531 * sem_ch12.adb (Check_Formal_Packages): Do not apply conformance
532 check if the instance is within an enclosing instance body. The
533 formal package was legal in the enclosing generic, and is
534 legal in the enclosing instantiation. This optimisation may be
535 applicable elsewhere, and it also removes spurious errors that
536 may arise with on-the-fly processing of instantiations that
537 contain Inline_Always subprograms.
539 2017-09-08 Vincent Celier <celier@adacore.com>
541 * gnatcmd.adb: Disregard empty argument of GNAT driver.
543 2017-09-08 Justin Squirek <squirek@adacore.com>
545 * checks.adb (Insert_Valid_Check): Manually decorate
546 the generated temporary for range valdity checks.
548 2017-09-08 Eric Botcazou <ebotcazou@adacore.com>
550 * usage.adb (Usage): Document new -gnatw.q/-gnatw.Q switches.
552 2017-09-08 Justin Squirek <squirek@adacore.com>
554 * switch-c.adb (Scan_Front_End_Switches): Add new warning switch
555 case to handle underscore flags.
556 * warnsw.adb, warnsw.ads (Set_Underscore_Warning_Switch): Create
557 new procedure to handle underscores.
559 2017-09-08 Javier Miranda <miranda@adacore.com>
561 * exp_ch4.adb (Expand_N_Op_Divide): Reordering code that handles
562 divisions with fixed point results to avoid generating twice
563 the runtime check on divide by zero.
564 * checks.adb (Apply_Divide_Checks): Ensure that operands are
565 not evaluated twice (once for their runtime checks and once for
566 their regular computation).
568 2017-09-08 Yannick Moy <moy@adacore.com>
570 * sem_prag.adb (Analyze_Part_Of): Add missing
571 return statements after issuing errors. Add detection of
572 out-of-order item and single concurrent type.

1058 * switch-c.adb (Scan_Front_End_Switches) <'R'>: Use case
1059 statement, accept '0' and set List_Representation_Info_Extended
1061 * usage.adb (Usage): Document new -gnatRe variant.
1063 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1065 * sem_prag.adb (Analyze_Pragma, case Default_Storage_Pool):
1066 Do not save the given entity in the global variable Default_Pool
1067 if the pragma appears within a generic unit.
1069 2017-09-08 Bob Duff <duff@adacore.com>
1071 * errout.adb (Delete_Warning): Do not
1072 decrement Warnings_Treated_As_Errors. This is called before
1073 Warnings_Treated_As_Errors has been incremented to account for
1074 this warning. Decrementing it here can lead to negative values
1075 of Warnings_Treated_As_Errors, raising Constraint_Error in
1076 checks-on builds, and causing the compiler to return an error
1077 code in checks-off builds.
1079 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1081 * sem_util.ads, sem_util.adb (Is_CCT_Instance): Only expect
1082 entities of named concurrent types as Ref_Id and not of anonymous
1083 concurrent objects (because callers already know when a conversion
1084 is necessary and can easily do it); also, do not expect protected
1085 types or protected objects as Context_Id (because no flow-related
1086 SPARK pragmas are attached there); reflect these changes in a
1087 more precise comment.
1089 2017-09-08 Olivier Hainque <hainque@adacore.com>
1091 * g-altive.ads: Add documentation.
1093 2017-09-08 Bob Duff <duff@adacore.com>
1095 * sem_util.ads, debug.adb: Minor comment fix.
1096 * erroutc.ads: Comment fix.
1098 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1100 * sem_ch12.adb (Validate_Array_Type_Instance): Suppress check
1101 for compatibility of component types of formal and actual in an
1102 instantiation of a child unit, when the component type of the
1103 formal is itself a formal of an enclosing generic.
1105 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1107 * sem_util.ads, sem_util.adb (Is_CCT_Instance): moved from
1108 sem_prag.adb to make it available for GNATprove; for concurrent
1109 types replace custom scope climbing with Scope_Same_Or_Within; for
1110 single concurrent objects add scope climbing (with Scope_Within),
1111 which was not there (that's the primary semantic change of this
1112 commit); also, when comparing a single concurrent object with
1113 its corresponding concurrent type rely on equality of types,
1114 not of objects (because that's simpler to code).
1115 * sem_prag.adb (Is_CCT_Instance): lifted to sem_util.ads.
1116 (Analyze_Global_Item): adjust special-casing of references to the
1117 current instance of a concurrent unit in the Global contracts
1118 of task types and single tasks objects; similar for references
1119 in the protected operations and entries of protected types and
1120 single protected objects (in all these cases the current instance
1121 behaves as an implicit parameter and must not be mentioned in
1122 the Global contract).
1124 2017-09-08 Arnaud Charlet <charlet@adacore.com>
1126 * exp_ch6.adb (Expand_Call_Helper): Introduce temporary for
1127 function calls returning a record within a subprogram call,
1130 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1132 * sem_ch8.adb (Find_Expanded_Name): Handle properly an expanded
1133 name that designates the current instance of a child unit in its
1134 own body and appears as the prefix of a reference to an entity
1135 local to the child unit.
1136 * exp_ch6.adb, freeze.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
1139 2017-09-08 Yannick Moy <moy@adacore.com>
1141 * sem_res.adb (Resolve_Equality_Op): Do not warn on comparisons that

1146 * sem_warn.adb (Check_Unused_Withs): Remove test that disabled
1147 warnings on internal units in configurable run time mode.
1149 2017-09-08 Bob Duff <duff@adacore.com>
1151 * sem_ch3.adb (Build_Derived_Private_Type): Inherit
1152 representation items from interfaces that the derived type
1153 implements, not just from the parent type.
1154 * sem_util.ads, sem_util.adb (Abstract_Interface_List): Change
1155 this to return an empty list when there are no interfaces.
1156 * einfo.ads, sem_ch13.adb: Minor comment fixes.
1157 * sem_attr.adb: Minor comment fix.
1159 2017-09-08 Doug Rupp <rupp@adacore.com>

1167 call to Allocate_Any_Controlled when the allocation does not
1168 require any initialization.
1170 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
1172 * sem_util.adb (Copy_Node_With_Replacement):
1173 Update the Renamed_Object field of a replicated object renaming
1176 2017-09-08 Patrick Bernardi <bernardi@adacore.com>
1178 * exp_ch9.adb (Is_Pure_Barrier): Allow type
1179 conversions and components of objects. Simplified the detection
1180 of the Count attribute by identifying the corresponding run-time
1183 2017-09-08 Yannick Moy <moy@adacore.com>
1185 * exp_ch9.adb, exp_disp.adb, repinfo.adb, sem_ch12.adb, sem_dim.adb,
1186 sem_type.adb, sinfo.ads: Minor reformatting.
1188 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1190 * freeze.adb (Has_Incomplete_Compoent): New predicate, subsidiary
1191 of Freeze_Profile, used to inhibit the freezing of the profile
1192 of an expression function declared within a nested package, when
1193 some type in the profile depends on a private type declared in
1194 an enclosing package.
1196 2017-09-08 Bob Duff <duff@adacore.com>
1198 * gnat1drv.adb (Gnat1drv): Do not set the Force_ALI_Tree_File flag in
1199 the subunit case. It's still OK to set it in the "missing subunits"
1200 case, because that won't cause the obsolete .ali files that cause
1203 2017-09-08 Bob Duff <duff@adacore.com>
1205 * sinput-l.adb: Remove unused "with Unchecked_Conversion;". It's
1206 unclear why this didn't cause a warning.
1207 * a-uncdea.ads, a-unccon.ads: Add "Ada." to names in the
1208 pragmas. It's unclear why this didn't cause an error.
1210 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>
1212 * exp_spark.adb (Expand_SPARK_N_Object_Renaming_Declaration):
1214 (Expand_SPARK_Potential_Renaming): Code clean up.
1215 * sem_prag.adb (Analyze_Initialization_Item): Add a guard in case
1216 the item does not have a proper entity.

1234 * repinfo.adb (List_Record_Info): During first loop,
1235 do not override the normalized position and first bit
1236 if they have already been set. Move fallback code
1237 for the packed case to the case where it belongs.
1238 * sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
1239 Also adjust the normalized position of components.
1240 (Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise.
1242 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1244 * exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
1245 the placement of a primitive operation O that renames an operation
1246 R declared in an inner package, and which is thus not a primitive
1247 of the dispatching type of O. In this case O is a new primitive
1248 and does not inherit its dispatch table position from R (which

1253 * sem_dim.adb (Analyze_Dimension_If_Expression,
1254 Analyze_Dimension_Case_Expression): new subprograms to verify
1255 the dimensional correctness of Ada2012 conditional expressions,
1256 and set properly the dimensions of the construct.
1257 * sem_res.adb (Resolve_If_Expression, Resolve_Case_Expression)):
1258 call Analyze_Dimension.

1263 loop on an interface declared as a private extension of another
1264 synchronized interface.
1266 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1268 * sem_ch12.adb (Check_Generic_Parent): New procedure within
1269 Analyze_Associations, to handle actual packages that depend on
1270 previous instances. If a package IAP that is an instantiation is
1271 used as an actual in a subsequent instantiation SI in the same
1272 scope, and IAP has a body, IAP must be frozen before SI. If
1273 the generic parent of IAP is itself declared in a previous
1274 instantiation in the same scope, that instantiation must also
1275 be frozen before SI.
1276 (Install_Body): Prevent double insertion of freeze node for
1279 2017-09-08 Hristian Kirtchev <kirtchev@adacore.com>

1287 * sem_ch13.adb (Analyze_Aspect_Specifications, case
1288 Linker_Section): If the aspect applies to an object declaration
1289 with explicit initialization, do not delay the freezing of the
1290 object, to prevent access-before-elaboration in the generated
1291 initialization code.
1293 2017-09-08 Ed Schonberg <schonberg@adacore.com>
1295 * a-wtdeio.adb (Put, all versions): Use Long_Long_Integer
1296 (Integer_Value (Item)) when the size of the fixed decimal type
1297 is larger than Integer.
1299 2017-09-07 Eric Botcazou <ebotcazou@adacore.com>
1302 * gcc-interface/decl.c (copy_and_substitute_in_layout): Put the fields
1303 in order of increasing position in more cases.

1330 * exp_disp.adb (Make_Tags): Avoid suffix counter
1331 in the external name of the elaboration flag. Required to fix
1332 the regressions introduced by the initial version of this patch.
1334 2017-09-07 Bob Duff <duff@adacore.com>
1336 * sem_ch6.adb (Analyze_Function_Return): Do not
1337 insert an explicit conversion to force the displacement of the
1338 "this" pointer to reference the secondary dispatch table in the
1339 case where the return statement is returning a raise expression,
1340 as in "return raise ...".
1342 2017-09-07 Arnaud Charlet <charlet@adacore.com>
1344 * sem_disp.adb (Is_User_Defined_Equality): Removed procedure.

1364 to handle properly various cases of type conversions where the
1365 target type and/or the expression carry dimension information.
1366 (Dimension_System_Root); If a subtype carries dimension
1367 information, obtain the source parent type that carries the

1374 2017-09-07 Ed Schonberg <schonberg@adacore.com>
1376 * exp_attr.adb (Expand_N_Attribute_Reference, case 'Constrained):
1377 If the prefix is a reference to an object, rewrite it as an
1378 explicit dereference, as required by 3.7.2 (2) and as is done
1379 with most other attributes whose prefix is an access value.
1381 2017-09-07 Bob Duff <duff@adacore.com>
1383 * par-ch13.adb: Set the Inside_Depends flag if we are inside a
1384 Refined_Depends aspect.

1392 * exp_ch7.adb (Insert_Actions_In_Scope_Around):
1393 Account for the case where the are no lists to insert, but the
1394 secondary stack still requires management.

1428 2017-09-07 Ed Schonberg <schonberg@adacore.com>
1430 * exp_disp.adb (Replace_Formals): If thr formal is classwide,
1431 and thus not a controlling argument, preserve its type after
1432 rewriting because it may appear in an nested call with a classwide
1435 2017-09-07 Arnaud Charlet <charlet@adacore.com>
1437 * comperr.adb (Delete_SCIL_Files): Handle case of

1443 clause for a unit U appears in a context that includes a regular
1444 with_clause on U, rewrite the redundant private clause into a null
1445 statement, rather than removing it altogether from the context,
1446 so that ASIS tools can reconstruct the original source.

1450 * sem_ch13.adb (Check_Aspect_At_Freeze_Point): The expression
1451 for aspect Small can be of any real type (not only a universal

1495 attribute. Defined for record types and subtypes.
1496 * exp_ch3.ads (Init_Secondary_Tags): Adding new formal

1498 IP routine to initialize the object components and for completing
1499 the elaboration of dispatch tables.
1500 * exp_ch3.adb (Build_Init_Procedure): Improve the code
1501 generated in the IP routines by means of keeping separate
1502 the initialization of the object components from the
1503 initialization of its dispatch tables. (Init_Secondary_Tags):
1504 Adding new formal (Init_Tags_List) and adjusting calls to
1505 Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;
1506 adjusting also calls to Ada.Tags.Register_Interface_Offset
1507 because the type of one of its formals has been changed.
1508 * a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
1509 modified. Instead of receiving a pointer to an object this
1510 routine receives now a primary tag.
1511 (Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
1512 additional formal: the tag of the primary dispatch table.
1513 * exp_disp.ads (Elab_Flag_Needed): New subprogram.

1528 * sem_util.adb (Check_Part_Of_Reference): rename Conc_Typ to Conc_Obj
1529 (because it refers to the anonymous concurrent object, not its type);
1530 fix condition for emitting error message about task/protected type,
1532 2017-09-07 Bob Duff <duff@adacore.com>

1543 2017-09-07 Arnaud Charlet <charlet@adacore.com>
1545 * sem_prag.adb (Find_Role): The Global_Seen flag
1546 is now consulted not only for abstract states and variables,
1547 but for all kinds of items.
1548 (Collect_Subprogram_Inputs_Outputs): Do not process formal
1549 generic parameters, because unlike ordinary formal parameters,
1550 generic formals only act as input/ outputs if they are explicitly
1551 mentioned in a Global contract.
1553 2017-09-07 Yannick Moy <moy@adacore.com>
1555 * ghost.adb (Check_Ghost_Context): Do not err on ghost code inside

1568 derived recor type, copy the dikensions if any of each component
1569 of the parent record to the corresponding component declarations

1587 * par-ch6.adb (P_Subprogram): Improve error message on null
1588 procedure with misplaced aspect specification, which the parser
1589 first attempts to interpret as a malformed expression function.
1591 2017-09-07 Gary Dismukes <dismukes@adacore.com>

1617 secondary stack for all functions that return limited tagged
1618 types -- just do it for dispatching calls. Misc cleanup.
1619 * sem_util.ads, sem_util.adb (Unqual_Conv): New function to
1620 remove qualifications and type conversions. Fix various bugs
1621 where only a single level of qualification or conversion was
1622 removed, so e.g. "T1'(T2'(X))" would incorrectly return "T2'(X)"
1624 * checks.adb, exp_util.ads, exp_util.adb, sem_res.adb: Misc related
1627 2017-09-07 Ed Schonberg <schonberg@adacore.com>
1629 * sem_ch6.adb (setr_Actual_Subtypes): Within a predicate function
1630 do not create actual subtypes that may generate further predicate

1633 of body is a predicate function as well.
1634 (Resolve_Aspect_Expressions, Resolve_Name): For a component
1635 association, only the expression needs resolution, not the name.
1636 (Resolve_Aspect_Expressions, case Predicates): Construct and

1681 * binde.adb (Find_Elab_Order): Do not run Elab_Old unless
1682 requested. Previously, the -do switch meant "run Elab_New and
1683 Elab_Old and use the order chosen by Elab_Old, possibly with
1684 debugging printouts comparing the two orders." Now it means
1685 "do not run Elab_New." This is of use if there are bugs that
1686 cause Elab_New to crash.

1704 <Sized_Component_Total_Round_RM_Size>: New local variable to
1705 accumulate the rounded RM_Size of components. Update it for
1706 every component whose RM_Size is statically known. Add missing
1707 guard to check that bit packing is really required before issuing
1708 the error about packing. Swap condition for clarity's sake.

1730 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1732 * sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
1733 entity of a mutable type and the right-hand side is a conditional
1734 expression, resolve the alternatives of the conditional using
1735 the base type of the target entity, because the alternatives
1736 may have distinct subtypes. This is particularly relevant if
1737 the alternatives are aggregates.
1739 2017-09-06 Ed Schonberg <schonberg@adacore.com>
1741 * checks.adb (Apply_Predicate_Check): If the expression is an
1742 aggregate that is the RHS of an assignment, apply the check to
1743 the LHS after the assignment, rather than to the aggregate. This
1744 is more efficient than creating a temporary for the aggregate,
1745 and prevents back-end crashes when the aggregate includes a
1746 dynamic "others' association.

1768 * errout.adb (Error_Msg): Separate the
1769 treatment for warning vs. style messages in inlinings and
1770 instantiations. Prevents blowups on calls to Warn_Insertion for
1771 style messages, which should not be called in that case because
1772 Warning_Msg_Char is not set.
1774 2017-09-06 Justin Squirek <squirek@adacore.com>

1777 to group all Volatile_Full_Access checks relating to other
1778 representation pragmas (Mark_Component_Or_Object): Created
1779 to centeralize the flagging of attributes for the record type
1780 component case, a pragma applied individually to a component, and

1799 * sem_ch12.adb (Copy_Generic_Node): When we copy a node
1800 that is a proper body corresponding to a stub, we defer the
1801 adjustment of the sloc until after the correct adjustment has
1802 been computed. Otherwise, Adjust_Instantiation_Sloc will ignore
1803 the adjustment, because it will be outside the range in (the old,
1804 incorrect) S_Adjustment.
1805 * inline.adb: Use named notation for readability and uniformity.
1806 * sinput-l.adb: Minor improvements to debugging output printed

1827 Linker_Section_Pragma.
1828 * exp_ch5.adb (Expand_Formal_Container_Loop): Add proper error
1829 checking for container loops so that the index cursor is not
1830 directly changable by the user with the use of E_Loop_Parameter.
1831 * sem_ch5.adb (Analyze_Block_Statement): Revert previous change.

1876 Generate a freeze node for the actual of a formal package, if
1877 the actual is declared in the same unit and has a corresponding
1878 body, to prevent the current instance from being frozen before

1905 (Strip): New routine.
1907 2017-09-06 Bob Duff <duff@adacore.com>
1909 * sysdep.c (__gnat_has_cap_sys_nice): If HAVE_CAPABILITY is defined,
1910 we include the proper header. Otherwise, we just declare the necessary
1911 things from the capabilities library. This is so we can build on
1912 machines without that library, while still enabling that library.
1913 At run time, we're using weak symbols, so __gnat_has_cap_sys_nice will
1914 simply return 0 if the library is not present, or not included

1930 has no parameter specification and no entry index, use the entry name
1931 as the end of the generated SCO statement.
1933 2017-09-06 Steve Baird <baird@adacore.com>
1935 * exp_util.adb (Side_Effect_Free): For CodePeer (only) treat
1936 uses of 'Image and related attributes as having side effects in
1937 order to avoid replicating such uses.
1938 * pprint.ads (Expression_Image) Add new generic formal flag
1939 Hide_Temp_Derefs. The flag defaults to False; CodePeer will
1940 (eventually) override the default.
1941 * pprint.adb (Expression_Image) If the new flag is set, then
1942 suppress the ".all" suffix when displaying a dereference whose
1943 prefix is a use of a value-capturing compiler temp of the sort
1944 generated by Expr_Util.Remove_Side_Effects .

2004 * freeze.adb (Check_Inherited_Conditions): Rewriting
2005 of inherited preconditions and postconditions should only occur
2006 in GNATprove mode, that is, when GNATprove_Mode is True, not to

2026 (Subprogram_Table): New instantiation of GNAT.Htable.Simple_HTable.
2027 (Is_Subprogram_Ref): Rename into...
2028 (Scan_Subprogram_Ref): ...this. Record references to subprograms in
2029 the table instead of bailing out on them. Scan the value of constants
2030 if it is not known at compile time.
2031 (Contains_Subprograms_Refs): Rename into...
2032 (Scan_Subprogram_Refs): ...this.
2033 (Has_Referencer): Scan the body of all inlined subprograms. Reset the

2149 that Ada.Command_Line contains modern Ada (the raise expression).
2150 * gnatbind.adb: Avoid dependence on

2290 of the right-hand side has stored constraint, use its values
2291 (except for those that are renamings of parent discriminants)

2293 left-hand side, which are invisible in the righ-hand side and
2294 not retrievable as selected components.
2296 2017-09-06 Ed Schonberg <schonberg@adacore.com>
2298 * sem_util.adb (Needs_One_Formal): The first formal of such a

2335 discriminants, the constraint for the target must obtain the
2336 discriminant values from both the operand and from the stored
2337 constraint for it, given that the constrained discriminants are
2338 not visible in the object.
2339 * exp_ch5.adb (Make_Field_Assign): The type of the right-hand
2340 side may be derived from that of the left-hand side (as in the
2341 case of an assignment with a change of representation) so the
2342 discriminant to be used in the retrieval of the value of the
2343 component must be the entity in the type of the right-hand side.

2372 in a set membership is an overloaded enumeration literal, and
2373 the type of the alternative is resolved from a previous one,

2918 * exp_ch6.adb (Expand_Call_Helper): When locating the
2919 accessibility entity created for an access parameter, handle
2920 properly a reference to a formal of an enclosing subprogram. if
2921 the reference appears in an inherited class-wide condition, it
2922 is the rewriting of the reference in the ancestor expression,
2923 but the accessibility entity must be that of the current formal.

2963 procedure body for a local (sub)type declaration within a
2964 predicate function. Invariant checks do not apply to these, and
2965 the expansion of the procedure will happen in the wrong scope,
2966 leading to misplaced freeze nodes.
2968 2017-05-02 Ed Schonberg <schonberg@adacore.com>
2970 * exp_util.adb (Insert_Library_Level_Action): Use proper scope
2971 to analyze generated actions. If the main unit is a body,

3007 * exp_disp.adb (Set_All_DT_Position, In_Predef_Prim_DT):
3008 Refine predicate for the case where the primitive operation
3009 is a renaming of equality. An overriding operation that is
3010 a user-defined renaming of predefined equality inherits its
3011 slot from the overridden operation. Otherwise it is treated
3012 as a predefined op and occupies the same predefined slot as
3013 equality. A call to it is transformed into a call to its alias,
3014 which is the predefined equality. A dispatching call thus uses
3015 the proper slot if operation is further inherited and called
3016 with class-wide arguments.
3018 2017-05-02 Justin Squirek <squirek@adacore.com>
3020 * errout.adb (Set_Msg_Text): Add a case to switch the message

3051 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3053 * exp_ch3.adb (Build_Initialization_Call): Generate a null
3054 statement if the initialization call is a null procedure, as
3055 can happen with a controlled type with no explicit Initialize
3056 procedure, or an array of such.
3057 * exp_ch7.adb (Process_Object_Declaration): For a type with
3058 controlled components that has a trivial Initialize procedure,
3059 insert declaration for finalization counter after object

3062 finalization block and attendant declarations if component has
3063 a trivial Initialize procedure.

3065 a trivial Initialize procedure.
3067 2017-05-02 Eric Botcazou <ebotcazou@adacore.com>

3098 parameter Array_Comp to indicate the case of an array object
3099 with null-excluding components.
3100 * checks.adb (Null_Exclusion_Static_Checks):
3101 Call Compile_Time_Constraint_Error instead of
3102 Apply_Compile_Time_Constraint_Error in the component case. Also
3103 call that when Array_Comp is True, with an appropriate warning for
3104 the array component case. Only create an explicit initialization
3105 by null in the case of an object of a null-excluding access type
3106 (and no longer do that in the component case).
3107 * sem_ch3.adb (Check_Component): Add a Boolean parameter
3108 Array_Comp defaulted to False. Pass Empty for the Comp
3109 actual when calling Null_Exclusion_Static_Checks in the case
3110 where Comp_Decl matches Object_Decl, because we don't have a
3111 component in that case. In the case of an object or component
3112 of an array type, pass True for Array_Comp on the recursive call
3115 2017-05-02 Bob Duff <duff@adacore.com>
3117 * s-taprop-linux.adb (Prio_To_Linux_Prio): New function to correctly
3118 compute the linux priority from the Ada priority. Call this everywhere
3119 required. In particular, the previous version was not doing this
3120 computation when setting the ceiling priority in various places. It
3121 was just converting to C.int, which results in a ceiling that is off

3158 visibility rules for equality operators that apply within an
3159 instantiation apply within an inlined body.
3160 * sem_type.adb (Add_One_Interp): ditto.

3197 a discriminant check when the associated type is a constrained
3198 subtype created for an unconstrained nominal type.
3199 * exp_attr.adb: Minor reformatting.
3201 2017-05-02 Bob Duff <duff@adacore.com>

3226 * checks.adb, sem_ch3.adb, sem_ch6.adb: Minor reformatting.
3228 2017-05-02 Bob Duff <duff@adacore.com>
3230 * exp_attr.adb (Callable, Identity, Terminated): Use Find_Prim_Op
3231 to find primitive ops, instead of using an Identifier that will
3232 later be looked up. This is necessary because these ops are not
3233 necessarily visible at all places where we need to call them.
3234 * exp_util.ads: Minor comment fix.
3236 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3238 * sem_ch6.adb (Fully_Conformant_Expressions): Two entity
3239 references are fully conformant if they are both expansions
3240 of the discriminant of a protected type, within one of the
3241 protected operations. One occurrence may be expanded into a
3242 constant declaration while the other is an input parameter to
3243 the corresponding generated subprogram.

3273 array components specially.
3275 2017-05-02 Ed Schonberg <schonberg@adacore.com>
3277 * sem_ch8.adb (Premature_Usage): If the premature usage of
3278 an entity is as the expression in its own object decaration,
3279 rewrite the reference as Any_Id to prevent cascaded errors or
3280 compiler loops when such an entity is used in an address clause.
3282 2017-05-01 Eric Botcazou <ebotcazou@adacore.com>
3284 * gcc-interface/decl.c (components_to_record): Add missing guard.

3289 Put back pending fields onto the regular list if the misalignment
3290 happens to cancel itself.
3292 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3294 * sem_ch4.adb (Complete_Object_Operation): When rewriting the
3295 controlling actual in a prefixed call, preserve the original node
3296 information if the prefix itself has been rewritten, for ASIS use.

3300 * exp_ch6.adb (Insert_Post_Call_Actions):
3301 Code clean up. Insert the post-call actions after an enclosing
3302 procedure call when N denotes a function call and appears as an
3303 actual parameter in the procedure call.
3305 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>
3307 * freeze.adb (Check_Component_Storage_Order): If there is a clause
3308 for the component, also reject the attribute if the component
3309 doesn't end on a byte boundary and its scalar storage order is
3310 different from that of the enclosing record type.
3312 2017-04-28 Javier Miranda <miranda@adacore.com>
3314 * atree.ads (Info_Messages): Removed.

3346 * sem_util.ads, sem_util.adb (Might_Raise): New function
3347 that replaces Is_Exception_Safe, but has the opposite
3348 sense. Is_Exception_Safe was missing various cases -- calls inside
3349 a pragma Debug, calls inside an 'if' or assignment statement,
3350 etc. Might_Raise now walks the entire subtree looking for things
3352 * exp_ch9.adb (Is_Exception_Safe): Remove.
3353 (Build_Protected_Subprogram_Body): Replace call to
3354 Is_Exception_Safe with "not Might_Raise". Misc cleanup (use
3355 constants where possible).
3356 * exp_ch7.adb: Rename Is_Protected_Body -->
3357 Is_Protected_Subp_Body. A protected_body is something different

3386 * sem_ch13.adb (Analyze_Aspect_Specifications, case
3387 Interrupt_Handler and Attach_Handler): Generate reference
3388 to protected operation to prevent spurious warnings about
3389 unreferenced entities. Previous scheme failed with style checks
3392 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3394 * sem_prag.adb (Relocate_Pragmas_To_Body): A pragma Warnings
3395 that follows an expression function must not be relocated to
3396 the generated body, because it applies to the code that follows.
3398 2017-04-28 Gary Dismukes <dismukes@adacore.com>
3400 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Test
3401 Relaxed_RM_Semantics to avoid having CodePeer issue errors on
3402 code that might violate the more stringent checking for 'Access
3403 introduced in Ada 2005.
3405 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3407 * a-cforse.adb: minor style fix in comment.
3409 2017-04-28 Eric Botcazou <ebotcazou@adacore.com>

3427 * sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
3428 node between access types, freeze the designated type as well,

3432 2017-04-28 Bob Duff <duff@adacore.com>
3434 * alloc.ads (Nodes_Initial): Go back to previous value. The large
3435 value makes large compilations faster, but small compilations slower.
3437 2017-04-28 Arnaud Charlet <charlet@adacore.com>
3439 * sem_util.adb: minor typos in Is_Child_Or_Sibling.

3457 2017-04-28 Ed Schonberg <schonberg@adacore.com>
3459 * sem_res.adb (In_Instance_Code): New predicate in
3460 Valid_Conversion, to determine whether a type conversion appears
3461 as (or within) an actual for a formal object. Type conversions
3462 in instances are not rechecked in Valid_Conversion because
3463 visibility changes between generic location andi instance may
3464 lead to spurious errors, but conversions within an actual must be
3465 fully checked, and they are not fully resolved when pre-analyzing
3468 2017-04-28 Hristian Kirtchev <kirtchev@adacore.com>
3470 * exp_ch6.adb (Expand_N_Extended_Return_Statement): Use
3471 New_Copy_Tree instead of Relocate_Node as any subsequent copies
3472 of the relocated node will have mangled Parent pointers.
3473 * sem_util.adb (Build_NCT_Hash_Tables): Reset both hash
3474 tables used in conjunction with entity and itype replication.
3475 (Visit_Entity): Rewrite the restriction on which entities

3514 components_to_record.
3515 (gnu_field_to_gnat): New function.
3516 (warn_on_field_placement): Likewise.
3517 (components_to_record): Add GNAT_RECORD_TYPE and remove REORDER
3518 parameters. Rename local variables and adjust recursive call.
3519 Rework final scan of the field list and implement warnings on the
3520 problematic placement of specific sorts of fields.

3530 For efficiency, cache results of Is_Internal_File_Name and
3531 Is_Predefined_File_Name in the Units table. This avoids a lot
3532 of repeated text processing.
3534 2017-04-27 Emmanuel Briot <briot@adacore.com>

3565 * exp_util.adb (Replace_Entity): The prefix of a 'Result
3566 attribute reference in a post- condition is the subprogram to
3567 which the condition applies. If the condition is inherited
3568 by a type extension, the prefix becomes a reference to the
3569 inherited operation, but there is no need to create a wrapper
3570 for this operation, because 'Result is expanded independently
3571 when elaborating the postconditions.

3583 Remove unused function.
3584 * alloc.ads (Nodes_Initial): Use a much larger value, because
3585 the compiler was spending a lot of time copying the nodes table
3586 when it grows. This number was chosen in 1996, so is rather out
3587 of date with current memory sizes. Anyway, it's virtual memory.
3588 Get rid of Orig_Nodes_...; use Node_... instead.
3589 * atree.adb (Lock): Do not release the Nodes tables; it's a
3591 Orig_Nodes_ ==> Nodes_
3592 * nlists.adb: Orig_Nodes_ ==> Nodes_

3637 of Expand_Dispatching_Call. If the denoted subprogram has a
3638 class-wide precondition, this is the only precondition that
3639 applies to the call, rather that the class-wide preconditions
3640 that may apply to the body that is executed. (This is specified

3657 * sem_attr.adb (Analyze_Attribute, case 'Image): In Ada2012 the
3658 prefix can be an object reference in which case Obj'Image (X)
3659 can only be interpreted as an indexing of the parameterless
3660 version of the attribute.
3661 * par-ch4.adb (P_Name): An attribute reference can be the prefix of
3662 an indexing or a slice operation if the attribute does not require
3663 parameters. In Ada2012 'Image also belongs in this category,
3664 and A'Image (lo .. hi) is legal and must be parsed as a slice.

4109 perform check if the current scope does not come from source,
4110 as is the case for a rewritten task body, because check has
4111 been performed already, and may not be doable because of changed

4167 modifications in functional containers.
4168 * a-cofuba.ads, a-cofuma.ads, a-cofuse.ads, a-cofuve.ads Reformat
4169 to improve readablity. Subprograms are separated between basic
4170 operations, constructors and properties. Universally quantified
4171 formulas in contracts are factorized in independant functions
4172 with a name and a comment. Names of parameters are improved.

4185 not install a predicate check if the object is initialized by
4186 means of a type conversion because the conversion is subjected

4262 * exp_ch7.adb (Establish_Transient_Scope): Rewrite
4263 the loop which detects potential enclosing transient scopes. The

4265 by packages and subprograms.
4267 2017-04-27 Claire Dross <dross@adacore.com>
4269 * a-cfdlli.adb, a-cfdlli.ads (=): Generic parameter removed to

4324 * debug.adb Change the documentation of switch -gnatd.s.
4325 * exp_ch7.adb (Make_Transient_Block): Transient blocks do not need
4326 to manage the secondary stack when an enclosing scope already
4327 performs this functionality (aka relaxed management). Switch
4328 -gnatd.s may be used to force strict management in which case
4329 the block will manage the secondary stack unconditionally. Add
4330 a guard to stop the traversal when encountering a package or a

4335 * sem_res.adb (Resolve_Call): Refine further the handling of
4336 limited views of return types in function calls. If the function
4337 that returns a limited view appears in the current unit,
4338 we do not replace its type by the non-limited view because
4339 this transformation is performed int the back-end. However,
4340 the type of the call itself must be the non-limited view, to
4341 prevent spurious resolution errors.
4343 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4345 * einfo,ads, einfo.adb (Class_Wide_Preconds, Class_Wide_Postconds):
4346 Removed, proposed implementation using generics for class-wide
4347 preconditions proved impractical.
4348 (Class_Wide_Clone): New attribute of subprogram. Designates
4349 subprogram created for primitive operations with class-wide
4350 pre/postconditions that contain calls to other primitives. The
4351 clone holds the body of the original primitive, but the
4352 pre/postonditions do not apply to it. The original body is
4353 rewritten as a wrapper for a call to the clone.
4354 (Is_Class_Wide_Clone): New flag to identify a Class_Wide_Clone. If
4355 the flag is set, no code for the corresponding pre/postconditions
4356 is inserted into its body.
4358 2017-04-27 Bob Duff <duff@adacore.com>
4360 * exp_prag.adb, par-prag.adb, sem_ch13.adb: Ignore

4408 maps which can be used as high level models for specification
4410 * a-cofuse.ads, a-cofuse.adb (Ada.Containers.Functional_Sets): New
4411 child of Ada.Containers. It provides functional indefinite unbounded
4412 sets which can be used as high level models for specification
4414 * a-cofuve.ads, a-cofuve.adb (Ada.Containers.Functional_Vectors): New
4415 child of Ada.Containers. It provides functional indefinite unbounded
4416 vectors which can be used as high level models for specification

4427 * sem_ch12.adb (Analyze_Associations): minor reformatting.
4428 (Check_Fixed_Point_Actual): Do not emit a warning on a fixed
4429 point type actual that has user-defined arithmetic primitives,
4430 when there is a previous actual for a formal package that defines
4431 a fixed-point type with the parent user-defined operator.
4433 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4435 * checks.adb (Generate_Range_Check): Reinstate part of previous change.

4437 the component type allows range checks.
4439 2017-04-27 Ed Schonberg <schonberg@adacore.com>
4441 * sem_aux.adb (Is_Generic_Formal): Use original node to locate
4442 corresponding declaration, because formal derived types are
4443 rewritten as private extensions.

4447 * sem_dim.adb (Analyze_Dimension_Binary_Op): Do not check
4448 dimensions of operands if node has been analyzed already, because
4449 previous analysis and dimension checking will have removed the
4450 dimension information from the operands.
4452 2017-04-27 Hristian Kirtchev <kirtchev@adacore.com>
4454 * debug.adb: Document the use of switch -gnatd.s.
4455 * einfo.ads Update the documentation on attribute
4456 Sec_Stack_Needed_For_Return and attribute Uses_Sec_Stack. Remove
4457 the uses of these attributes from certain entities.

4459 which determines whether the block should continue to manage
4460 the secondary stack.

4514 of silently ignoring pragma Ada_xxx in Latest_Ada_Only mode.
4515 * directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Use
4516 Ada_2012 instead of Ada_2005 to be compatible with the above
4518 * bindgen.adb: Silence new warning on pragma Ada_95.
4520 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

4537 * types.ads, osint.adb, sinput-c.adb, sinput-d.adb, sinput-l.adb,
4538 * sinput-p.adb: Use regular fat pointers, with bounds checking,
4539 for source buffers. Fix misc obscure bugs.
4540 * sinput.ads, sinput.adb: Use regular fat pointers, with bounds
4541 checking, for source buffers. Modify representation clause for
4542 Source_File_Record as appropriate. Move Source_File_Index_Table
4543 from spec to body, because it is not used outside the body.
4544 Move Set_Source_File_Index_Table into the private part, because
4545 it is used only in the body and in children. Use trickery to
4546 modify the dope in the generic instantiation case. It's ugly,
4547 but not as ugly as the previous method. Fix documentation.

5074 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5076 * sem_warn.adb (Warn_On_Overlapping_Actuals): There can be no
5077 overlap if the two formals have different types, because formally
5078 the corresponding actuals cannot designate the same objects.
5080 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5082 * sem_dim.adb (Dimensions_Of_Operand): minot cleanups: a) If
5083 dimensions are present from context, use them. b) If operand is
5084 a static constant rewritten as a literal, obtain the dimensions
5085 from the original declaration, otherwise use dimensions of type
5086 established from context.
5088 2017-04-25 Yannick Moy <moy@adacore.com>
5090 * sem_util.adb (Is_Effectively_Volatile): Protect against base type

5103 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5105 * sem_disp.adb (Check_Dispatching_Context): Add guard to refine
5106 the check that recognizes a call to a private overridding and
5107 replaces the called subprogram with its alias.
5109 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5111 * exp_util.adb: Minor reformatting.
5113 2017-04-25 Justin Squirek <squirek@adacore.com>
5115 * exp_ch3.adb (Freeze_Type): Add condition to always treat
5116 interface types as a partial view of a private type for the
5117 generation of invariant procedure bodies.
5118 * exp_util.adb, exp_util.ads (Add_Inherited_Invariants):
5119 Add a condition to get the Corresponding_Record_Type for
5120 concurrent types, add condition to return in the absence of a
5121 class in the pragma, remove call to Replace_Type_References,
5122 and add call to Replace_References.
5123 (Add_Interface_Invariatns),
5124 (Add_Parent_Invariants): Modify call to Add_Inherited_Invariants
5125 to including the working type T.
5126 (Add_Own_Invariants): Remove
5127 legacy condition for separate units, remove dispatching for ASIS
5128 and save a copy of the expression in the pragma expression.
5129 (Build_Invariant_Procedure_Body): Default initalize vars,
5130 remove return condition on interfaces, always use the
5131 private type for interfaces, and move the processing of types
5132 until after the processing of invariants for the full view.
5133 (Build_Invariant_Procedure_Declaration): Remove condition
5134 to return if an interface type is encountered and add
5135 condition to convert the formal parameter to its class-wide
5136 counterpart if Work_Typ is abstract.
5137 (Replace_Type): Add call to Remove_Controlling_Arguments.
5138 (Replace_Type_Ref): Remove class-wide dispatching for the current
5139 instance of the type.
5140 (Replace_Type_References): Remove parameter "Derived"
5141 (Remove_Controlling_Arguments): Created in order to removing
5142 the controlliong argument from calls to primitives in the case
5143 of the formal parameter being an class-wide abstract type.
5144 * sem_ch3.adb (Build_Assertion_Bodies_For_Type): Almost identical
5145 to the change made to Freeze_Type in exp_ch3. Add a condition
5146 to treat interface types as a partial view.
5147 * sem_prag.adb (Analyze_Pragma): Modify parameters in the call
5148 to Build_Invariant_Procedure_Declaration to properly generate a
5149 "partial" invariant procedure when Typ is an interface.

5156 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5158 * sem_ch3.adb (Derive_Subprogram): Implement rule in RM 6.1.1
5159 (10-15): if derived type T with progenitors is abstract,
5160 and primitive P of this type inherits non-trivial classwide
5161 preconditions from both a parent operation and from an interface
5162 operation, then the inherited operation is abstract if the parent
5163 operation is not null.
5164 * sem_disp.ads, sem_disp.adb: replace function Covers_Some_Interface
5165 with Covered_Interface_Op to yield the actual interface operation
5166 that is implemented by a given inherited operation.
5168 2017-04-25 Javier Miranda <miranda@adacore.com>
5170 * exp_ch4.adb (Expand_N_Op_Expon): Relocate left
5171 and right operands after performing the validity checks. Required
5172 because validity checks may remove side effects from the operands.
5174 2017-04-25 Javier Miranda <miranda@adacore.com>
5176 * exp_attr.adb (Attribute_Unrestricted_Access):
5177 Do not disable implicit type conversion. Required to generate

5189 values, and comparing them must use Expr_Value_S.
5191 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5193 * sem_ch4.adb (Complete_Object_Interpretation): If an explicit
5194 dereference is introduced for the object, and the object is
5195 overloaded, do not check whether it is aliased, because it may
5196 include an implicit dereference.
5197 * sem_type.adb (Disambiguate): If two interpretations are access
5198 attribute types with the same designated type keep either of
5199 them and do not report an ambiguity. A true ambiguity will be
5202 2017-04-25 Bob Duff <duff@adacore.com>
5204 * a-numeri.ads: Change the encoding of Greek letter Pi from
5205 brackets encoding to UTF-8. Use pragma Wide_Character_Encoding
5206 to indicate the encoding. We considered using a byte order mark
5207 (BOM), but that causes various trouble (misc software eats the
5208 BOM, if you have a patch with a BOM, then it's not at the start
5209 of the patch, so it's not a BOM, the BOM affects with-ing files,
5211 * scng.adb, s-wchcnv.adb: Minor.

5252 * sem_ch3.adb (Has_Non_Trivial_Precondition): New predicate to
5253 enforce legality rule on classwide preconditions inherited from
5254 both an ancestor and a progenitor (RM 6.1.1 (10-13).
5255 * sem_disp.adb (Check_Dispatching_Context): A call to an abstract
5256 subprogram need not be dispatching if it appears in a precondition
5257 for an abstract or null subprogram.
5259 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5261 * sem_ch10.adb: Minor typo fix.
5263 2017-04-25 Arnaud Charlet <charlet@adacore.com>
5265 * gcc-interface/Makefile.in: Cleanup VxWorks targets.
5267 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>

5271 (Is_Predefined_File_Name): Likewise. Adjust comment.
5273 2017-04-25 Bob Duff <duff@adacore.com>
5275 * exp_aggr.adb (Component_Count): Protect the
5276 arithmetic from attempting to convert a value >= 2**31 to Int,
5277 which would otherwise raise Constraint_Error.
5279 2017-04-25 Bob Duff <duff@adacore.com>
5281 * opt.ads (Locking_Policy): Fix incorrect documentation. The
5282 first character of the policy name is not unique.
5284 2017-04-25 Bob Duff <duff@adacore.com>
5286 * s-fileio.adb (Name): Raise Use_Error if the file is a temp file.
5287 * s-ficobl.ads (Is_Temporary_File): Remove incorrect comment

5305 Save and restore the value of global flag
5306 Ignore_SPARK_Mode_Pragmas_In_Instance. Set or reinstate the value

5308 the corresponding spec or the body must ignore all SPARK_Mode
5309 pragmas found within.
5310 (Analyze_Subprogram_Declaration): Mark
5311 the spec when it needs to ignore all SPARK_Mode pragmas found
5312 within to allow the body to infer this property in case it is
5313 instantiated or inlined later.
5314 * sem_ch7.adb (Analyze_Package_Body_Helper): Save and restore the
5315 value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set
5316 the value of global flag Ignore_SPARK_Mode_Pragmas_In_Instance
5317 when the corresponding spec also ignored all SPARK_Mode pragmas
5319 (Analyze_Package_Declaration): Mark the spec when
5320 it needs to ignore all SPARK_Mode pragmas found within to allow
5321 the body to infer this property in case it is instantiated or
5323 * sem_ch12.adb (Analyze_Formal_Package_Declaration):
5324 Save and restore the value of flag
5325 Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
5326 formal spec when it needs to ignore all SPARK_Mode
5327 pragmas found within to allow the body to infer this
5328 property in case it is instantiated or inlined later.
5329 (Analyze_Package_Instantiation): Save and restore the value
5330 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark
5331 the instance spec when it needs to ignore all SPARK_Mode
5332 pragmas found within to allow the body to infer this
5333 property in case it is instantiated or inlined later.

5335 of global flag Ignore_SPARK_Mode_Pragmas_In_Instance. Mark the
5336 instance spec and anonymous package when they need to ignore
5337 all SPARK_Mode pragmas found within to allow the body to infer

5339 (Instantiate_Package_Body): Save and restore the value of global
5340 flag Ignore_SPARK_Mode_Pragmas_In_Instance. Set the value of

5350 Ignore_Pragma_SPARK_Mode.
5351 * sem_util.adb (SPARK_Mode_Is_Off): A construct which ignored
5352 all SPARK_Mode pragmas defined within yields mode "off".
5354 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

5373 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5375 * sem_util.adb (New_Copy_Tree): Put back the declarations of the
5376 hash tables at library level. Reinstate the NCT_Hash_Tables_Used
5377 variable and set it to True whenever the main hash table is
5378 populated. Short- circuit the Assoc function if it is false
5379 and add associated guards.
5381 2017-04-25 Olivier Hainque <hainque@adacore.com>
5383 * bindgen.adb (Gen_Elab_Calls): Also update counter of lone
5384 specs without elaboration code that have an elaboration counter
5385 nevertheless, e.g. when compiled with -fpreserve-control-flow.
5386 * sem_ch10.adb (Analyze_Compilation_Unit):
5387 Set_Elaboration_Entity_Required when requested to preserve
5388 control flow, to ensure the unit elaboration is materialized at
5389 bind time, resulting in the inclusion of the unit object file
5390 in the executable closure at link time.
5392 2017-04-25 Pierre-Marie de Rodat <derodat@adacore.com>
5394 * exp_dbug.adb: In Debug_Renaming_Declaration,
5395 when dealing with indexed component, accept to produce a renaming
5396 symbol when the index is an IN parameter or when it is a name
5397 defined in an outer scope.
5399 2017-04-25 Yannick Moy <moy@adacore.com>
5401 * errout.adb (Error_Msg): Adapt continuation
5402 message in instantiations and inlined bodies for info messages.
5404 2017-04-25 Eric Botcazou <ebotcazou@adacore.com>
5406 * fname.adb (Has_Internal_Extension): Add pragma Inline.
5407 Use direct 4-character slice comparisons.
5409 pragma Inline. (Has_Suffix): Delete.
5410 (Is_Internal_File_Name):
5411 Test Is_Predefined_File_Name first.
5412 (Is_Predefined_File_Name):

5416 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5418 * checks.adb (Insert_Valid_Check): Code cleanup.
5419 * exp_ch6.adb (Add_Validation_Call_By_Copy_Code): New routine.
5420 (Expand_Actuals): Generate proper copy-back for a validation
5421 variable when it acts as the argument of a type conversion.
5422 * sem_util.adb (Is_Validation_Variable_Reference): Augment the
5423 predicate to operate on type qualifications.
5425 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5427 * sem_prag.adb, exp_ch6.adb, binde.adb, sem_disp.adb, s-fileio.adb:
5430 2017-04-25 Bob Duff <duff@adacore.com>
5432 * sem_prag.adb (No_Return): Give an error if the pragma applies
5433 to a body. Specialize the error for the specless body case,
5434 as is done for (e.g.) pragma Convention.
5435 * debug.adb: Add switch -gnatd.J to disable the above legality
5436 checks. This is mainly for use in our test suite, to avoid
5437 rewriting a lot of illegal (but working) code. It might also
5438 be useful to customers. Under this switch, if a pragma No_Return
5439 applies to a body, and the procedure raises an exception (as it
5440 should), the pragma has no effect. If the procedure does return,
5441 execution is erroneous.
5443 2017-04-25 Bob Duff <duff@adacore.com>
5445 * exp_ch6.adb (Expand_Actuals): This is the
5446 root of the problem. It took N as an 'in out' parameter, and in
5447 some cases, rewrote N, but then set N to Original_Node(N). So
5448 the node returned in N had no Parent. The caller continued
5449 processing of this orphaned node. In some cases that caused a
5450 crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
5451 and trips over the Empty Parent). The solution is to make N an
5452 'in' parameter. Instead of rewriting it, return the list of
5453 post-call actions, so the caller can do the rewriting later,
5454 after N has been fully processed.
5455 (Expand_Call_Helper): Move most of Expand_Call here. It has
5456 too many premature 'return' statements, and we want to do the
5457 rewriting on return.
5458 (Insert_Post_Call_Actions): New procedure to insert the post-call
5459 actions in the appropriate place. In the problematic case,
5460 that involves rewriting N as an Expression_With_Actions.
5461 (Expand_Call): Call the new procedures Expand_Call_Helper and
5462 Insert_Post_Call_Actions.
5464 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5466 * sem_prag.adb (Inherits_Class_Wide_Pre): Cleanup code, handle
5467 properly type derived from generic formal types, to handle
5468 properly modified version of ACATS 4.1B B611017.
5470 2017-04-25 Javier Miranda <miranda@adacore.com>
5472 * exp_unst.adb (Subp_Index): Adding missing
5473 support for renamings and functions that return a constrained
5474 array type (i.e. functions for which the frontend built a
5475 procedure with an extra out parameter).
5477 2017-04-25 Pascal Obry <obry@adacore.com>
5479 * s-string.adb: Minor code clean-up.
5481 2017-04-25 Bob Duff <duff@adacore.com>

5486 function for Non_Blocking_Wait_Process.
5488 2017-04-25 Bob Duff <duff@adacore.com>
5490 * prep.adb (Preprocess): Remove incorrect
5491 Assert. Current character can be ASCII.CR.
5493 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5495 * sem_prag.adb (Set_Convention_From_Pragma): Cleanup code for
5496 convention Stdcall, which has a number of exceptions. Convention
5497 is legal on a component declaration whose type is an anonymous
5498 access to subprogram.
5500 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5502 * sem_ch4.adb: sem_ch4.adb Various reformattings.
5503 (Try_One_Prefix_Interpretation): Use the base type when dealing
5504 with a subtype created for purposes of constraining a private
5505 type with discriminants.
5507 2017-04-25 Javier Miranda <miranda@adacore.com>
5509 * einfo.ads, einfo.adb (Has_Private_Extension): new attribute.
5510 * warnsw.ads, warnsw.adb (All_Warnings): Set warning on late
5511 dispatching primitives (Restore_Warnings): Restore warning on
5512 late dispatching primitives (Save_Warnings): Save warning on late
5513 dispatching primitives (Do_Warning_Switch): Use -gnatw.j/-gnatw.J
5514 to enable/disable this warning.
5515 (WA_Warnings): Set warning on late dispatching primitives.
5516 * sem_ch3.adb (Analyze_Private_Extension_Declaration): Remember
5517 that its parent type has a private extension.
5518 * sem_disp.adb (Warn_On_Late_Primitive_After_Private_Extension):
5520 * usage.adb: Document -gnatw.j and -gnatw.J.
5522 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5524 * exp_ch7.adb, checks.adb, sem_prag.adb, eval_fat.adb: Minor
5527 2017-04-25 Bob Duff <duff@adacore.com>
5529 * binde.adb (Validate): Do not pass dynamic strings
5530 to pragma Assert, because older compilers do not support that.
5532 2017-04-25 Bob Duff <duff@adacore.com>
5534 * s-fileio.adb (Close): When a temp file is
5535 closed, delete it and clean up its Temp_File_Record immediately,
5536 rather than waiting until later.
5537 (Temp_File_Record): Add File
5538 component, so Close can know which Temp_File_Record corresponds
5539 to the file being closed.
5540 (Delete): Don't delete temp files,
5541 because they are deleted by Close.
5542 (Open): Set the File component
5543 of Temp_File_Record. This requires moving the creation of the
5544 Temp_File_Record to the end, after the AFCB has been created.
5546 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5548 * checks.adb (Insert_Valid_Check): Do not generate
5549 a validity check when inside a generic.

5558 potentially blocking subprograms.
5560 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5562 * sem_prag.adb (Analyze_Pre_Post_Condition): The rules
5563 concerning inheritance of class-wide preconditions do not apply
5566 2017-04-25 Bob Duff <duff@adacore.com>
5568 * s-ficobl.ads: Minor comment fix.
5570 2017-04-25 Yannick Moy <moy@adacore.com>
5572 * checks.adb (Apply_Scalar_Range_Check): Analyze precisely
5573 conversions from float to integer in GNATprove mode.
5574 (Apply_Type_Conversion_Checks): Make sure in GNATprove mode
5575 to call Apply_Type_Conversion_Checks, so that range checks
5576 are properly positioned when needed on conversions, including
5577 when converting from float to integer. (Determine_Range): In
5578 GNATprove mode, take into account the possibility of conversion
5579 from float to integer.

5587 * checks.adb (Determine_Range_R): Special case type conversions
5588 from integer to float in order to get bounds in that case too.

5604 * exp_attr.adb (Make_Range_Test): Add processing for validation
5605 variables to avoid extra reads and copies of the prefix.

5607 variables in order to reflect any changes done in the variable
5608 back into the original object.

5624 Pre'Class aspect is specified for the corresponding primitive
5625 subprogram of some ancestor of T.
5627 2017-04-25 Bob Duff <duff@adacore.com>
5629 * sem_ch8.adb (Use_One_Type): If a use_type_clause
5630 is redundant, set its Used_Operations to empty. This is only
5631 necessary for use clauses that appear in the parent of a generic
5632 child unit, because those use clauses get reanalyzed when we
5633 instantiate the generic, and we don't want the Used_Operations
5634 carried over from the original context (where it was probably

5652 * sem_ch8.adb (Find_Type): For an attribute reference
5653 'Class, if prefix type is synchronized and previous errors
5654 have suppressed the creation of the corresponding record type,
5655 create a spurious class-wide for the synchonized type itself,
5656 to catch other misuses of the attribute
5658 2017-04-25 Steve Baird <baird@adacore.com>
5660 * exp_ch6.adb (Expand_Simple_Function_Return): if CodePeer_Mode
5661 is True, then don't generate the accessibility check for the

5665 tag checks for the result of call to an instance of
5666 Ada.Tags.Generic_Dispatching_Constructor (i.e., both the "is a
5667 descendant of" check and the accessibility check).

5678 (Expand_Concatenate): When optimization is enabled, also expand
5679 the operation out-of-line if the concatenation is present within
5680 the expression of the declaration of a library-level object and
5681 not only if it is the expression of the declaration.
5683 2017-04-25 Bob Duff <duff@adacore.com>
5685 * freeze.adb (Freeze_Object_Declaration): Do
5686 not Remove_Side_Effects if there is a pragma Linker_Section,
5687 because in that case we want static initialization in the
5688 appropriate section.
5690 2017-04-25 Gary Dismukes <dismukes@adacore.com>
5692 * exp_dbug.adb: Minor rewording and reformatting.
5694 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5696 * sem_attr.adb (Statically_Denotes_Object): New predicate, to
5697 handle the proposed changes to rules concerning potentially
5698 unevaluated expressions, to include selected components that
5699 do not depend on discriminants, and indexed components with
5701 * sem_util.adb (Is_Potentially_Unevaluated): Add check for
5702 predicate in quantified expression, and fix bugs in the handling
5703 of case expressions and membership test.

5721 renaming entity for debug information, mark the entity as needing debug
5722 info if it comes from sources.
5724 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5726 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Remove the

5746 internal calls that appear in preconditions of protected
5747 operations, in default values for same, and in contract guards

5759 * a-numaux-x86.ads: Fix package description.
5760 * a-numaux-x86.adb (Is_Nan): Minor tweak.

5762 testing manually. Use an integer temporary to hold rounded value.
5763 * a-numaux-darwin.adb (Reduce): Likewise.
5764 (Is_Nan): New function.
5766 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5768 * sem_ch4.adb (Analyze_Selected_Component): Additional refinement
5769 on analysis of prefix whose type is a current instance of a
5770 synchronized type, but where the prefix itself is an entity that

5775 * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve
5776 the identity of callable entities therein, because they have been
5777 properly resolved, and prefixed calls may have been rewritten

5782 * exp_ch3.adb (Build_Init_Statements): Convert
5783 the expression of the pragma/aspect Secondary_Stack_Size to

5798 2017-04-25 Javier Miranda <miranda@adacore.com>
5800 * urealp.adb (UR_Write): Reverse previous patch
5801 adding documentation on why we generate multiplications instead
5802 of divisions (needed to avoid expressions whose computation with
5803 large numbers may cause division by 0).
5805 2017-04-25 Bob Duff <duff@adacore.com>
5807 * erroutc.adb (Set_Specific_Warning_Off,
5808 Set_Warnings_Mode_Off): Use the correct source file for
5809 Stop. Was using Current_Source_File, which is only valid during
5810 parsing. Current_Source_File will have a leftover value from
5811 whatever file happened to be parsed last, because of a with_clause
5814 2017-04-25 Bob Duff <duff@adacore.com>
5816 * lib.ads, lib.adb (In_Internal_Unit): New functions similar
5817 to In_Predefined_Unit, but including GNAT units.
5818 * sem_util.ads, sem_util.adb (Should_Ignore_Pragma): Replace
5819 with Should_Ignore_Pragma_Par and Should_Ignore_Pragma_Sem,
5820 because Should_Ignore_Pragma was not working reliably outside
5821 the parser, because Current_Source_File is not valid.
5822 * sem_prag.adb, exp_prag.adb: Call Should_Ignore_Pragma_Sem.
5823 * par-prag.adb: Call Should_Ignore_Pragma_Par.

5890 2017-04-25 Ed Schonberg <schonberg@adacore.com>
5892 * sem_ch4.adb (Analyze_Selected_Component): Refine analysis
5893 of prefix whose type is a current instance of a synchronized
5894 type. If the prefix is an object this is an external call (or
5895 requeue) that can only access public operations of the object. The
5896 previous predicate was too restrictive, and did not allow public
5897 protected operations, only task entries.
5899 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>
5901 * sem_ch5.adb, fname.adb: Minor reformatting.
5903 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com>

5911 master for an access type subject to pragma No_Heap_Finalization.
5912 * exp_util.adb (Build_Allocate_Deallocate_Proc): An object being
5913 allocated or deallocated does not finalization actions if the
5914 associated access type is subject to pragma No_Heap_Finalization.
5915 * opt.ads Add new global variable No_Heap_Finalization_Pragma.
5916 * par-prag.adb Pragma No_Heap_Finalization does not need special
5917 processing from the parser.
5918 * sem_ch6.adb (Check_Return_Subtype_Indication): Remove ancient
5919 ??? comments. Use the new predicate Is_Anonymous_Access_Type.
5920 * sem_prag.adb Add an entry in table Sig_Flags for pragma
5921 No_Heap_Finalization.
5922 (Analyze_Pragma): Add processing for

5931 * freeze.adb (Freeze_Record_Type): Use the
5932 underlying type of the component type to determine whether it's
5933 elementary. For representation clause purposes, a private type
5934 should behave the same as its full type.
5935 * fname.ads, fname.adb (Is_Predefined_File_Name):
5936 Make sure things like "system.ali" are recognized as predefined.
5938 2017-04-25 Javier Miranda <miranda@adacore.com>

5944 * sem_ch5.adb (Preanalyze_Range): Handle properly an Ada2012
5945 element iterator when the name is an overloaded function call,
5946 one of whose interpretations yields an array.
5948 2017-04-25 Bob Duff <duff@adacore.com>
5950 * uname.ads, uname.adb (Is_Predefined_Unit_Name,
5951 Is_Internal_Unit_Name): New functions for operating on unit
5952 names, as opposed to file names. There's some duplicated code
5953 with fname.adb, which is unfortunate, but it seems like we don't
5954 want to add dependencies here.
5955 * fname-uf.adb (Get_File_Name): Change Is_Predefined_File_Name
5956 to Is_Predefined_Unit_Name; the former was wrong, because Uname
5957 is not a file name at all.
5958 * fname.ads, fname.adb: Document the fact that
5959 Is_Predefined_File_Name and Is_Internal_File_Name can be called
5960 for ALI files, and fix the code so it works properly for ALI
5961 files. E.g. these should return True for "system.ali".
5963 2017-04-25 Justin Squirek <squirek@adacore.com>
5965 * exp_util.adb (Add_Invariant): Removed,
5966 code moved to Add_Invariant_Check, Add_Inherited_Invariant,
5967 and Add_Own_Invariant. (Add_Invariant_Check): Used
5968 for adding runtime checks from any kind of invariant.
5969 (Add_Inherited_Invariant): Generates invariant checks for
5970 class-wide invariants (Add_Interface_Invariants): Removed, code
5971 moved to Build_Invariant_Procedure_Body (Add_Own_Invariant):
5972 Create a types own invariant procedure (Add_Parent_Invariants):
5973 Removed, code moved to Build_Invariant_Procedure_Body
5974 (Build_Invariant_Procedure_Body): Add refactored calls
5975 and integrated code from Add_Parent_Invariants and
5976 Add_Interface_Invariants.
5977 (Process_Type): Removed, the
5978 relavant code was inlined into both Add_Own_Invariant and
5979 Add_Inherited_Invariant.

6002 and Build_Invariant_Procedure_Declaration from exp_ch7
6003 and break-out Is_Untagged_Private_Derivation from
6004 Build_Invariant_Procedure_Body.
6005 (Replace_Type_References):
6006 Append an extra parameter to allow for dispatching replacements
6007 and add the corrasponding logic.
6008 (Type_Invariant): Remove
6009 Replace_Typ_Refs and replace its references with calls to
6010 Replace_Type_References.
6011 * sem_ch3.adb, sem_prag.adb: Remove with and use of exp_ch7.
6013 2017-04-25 Bob Duff <duff@adacore.com>

6016 that returns True when appropriate.
6017 * par-prag.adb, exp_prag.adb, sem_prag.adb: Do not ignore pragmas
6018 when compiling predefined files.
6019 * fname.ads, fname.adb (Is_Predefined_File_Name): Fix bug:
6020 "gnat.adc" should not be considered a predefined file name.
6021 That required (or at least encouraged) a lot of cleanup of global
6022 variable usage. We shouldn't be communicating information via
6023 the global name buffer.
6024 * bindgen.adb, errout.adb, fname-uf.adb, lib-load.adb, make.adb,
6025 * restrict.adb, sem_ch10.adb, sem_ch6.adb, sem_ch8.adb: Changes

6056 * par-ch2.adb, scans.ads, scn.adb: Do not give an error for
6057 reserved words inside pragmas. This is necessary to allow the
6058 pragma name Interface to be used in pragma Ignore_Pragma.
6059 * par.adb: Minor comment fix.

6845 variables to the local variable section. Update the profile
6846 of various nested routine that previously had visibility
6847 of those globals. One the matching phase has completed,

6849 (Check_Dependency_Clause): Properly detect a match between two
6850 'Result attributes. Update the various post-match cases to use
6851 Is_Already_Matched as this routine now automatically recognizes
6852 a previously matched 'Result attribute.
6853 (Is_Already_Matched): New routine.
6854 (Remove_Extra_Clauses): New routine.
6855 (Report_Extra_Clauses): Remove the detection of ... => null

6914 subsidiary to Expand_N_Object_ Declaration, to compute a guard on
6915 an object declaration for an array type with a modular index type
6916 with the size of Long_Long_Integer. Special processing is needed
6917 in this case to compute reliably the size of the object, and
6918 eventually to raise Storage_Error, when wrap-around arithmetic
6919 might compute a meangingless size for the object.
6921 2017-01-23 Justin Squirek <squirek@adacore.com>
6923 * a-wtenau.adb, par-endh.adb, sem_prag.adb,

6928 * sem_res.adb (Resolve_Call): In the part of the code where
6929 it is deciding whether to turn the call into an indexed
6930 component, avoid doing so if the call is to an instance of
6931 Unchecked_Conversion. Otherwise, the compiler turns it into an
6932 indexed component, and resolution of that turns it back into a
6933 function call, and so on, resulting in infinite recursion.
6934 * sem_util.adb (Needs_One_Actual): If the first formal has a
6935 default, then return False.

6975 * sem_ch9.adb (Analyze_Delay_Relative): in GNATprove mode a delay
6976 relative statement introduces an implicit dependency on
6977 Ada.Real_Time.Clock_Time.

6980 2017-01-20 Ed Schonberg <schonberg@adacore.com>
6982 * sem_ch13.adb (Analyze_Aspect_Specifications): Aspect Alignment
6983 must be treated as delayed aspect even if the expression is
6984 a literal, because the aspect affects the freezing and the
6985 elaboration of the object to which it applies.

7006 the prefix is not null) when the prefix denotes an object of an
7007 access type; that is, when there is an implicit dereference.

7037 returns a limited view of a type and at the point of the call the
7038 function is not declared in the extended main unit then replace
7039 it with the non-limited view, which must be available. If the
7040 called function is in the extended main unit then no action is
7041 needed since the back-end handles this case.
7043 2017-01-20 Eric Botcazou <ebotcazou@adacore.com>
7045 * sem_ch7.adb (Contains_Subp_Or_Const_Refs): Rename into...

7055 * sem_ch3.adb (Complete_Private_Subtype): If the scope of the
7056 base type differs from that of the completion and the private
7057 subtype is an itype (created for a constraint on an access
7058 type e.g.), set Delayed_Freeze on both to prevent out-of-scope
7061 2017-01-20 Hristian Kirtchev <kirtchev@adacore.com>
7063 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
7064 When inheriting the SPARK_Mode of a prior expression function,

7068 2017-01-20 Ed Schonberg <schonberg@adacore.com>
7070 * sem_prag.adb (Rewrite_Assertion_Kind): If the name is
7071 Precondition or Postcondition, and the context is pragma

7586 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
7588 * sem_ch6.adb (Analyze_Subprogram_Body_Helper):
7589 Ensure that the input body is a subprogram body before trying to
7590 determine whether it denoted an expression function. Note that
7591 subprogram body stubs cannot denote expression functions.
7593 2017-01-13 Gary Dismukes <dismukes@adacore.com>
7595 * bindgen.adb, sem_ch6.adb, binde.adb, exp_ch3.adb: Minor reformatting
7598 2017-01-13 Javier Miranda <miranda@adacore.com>
7600 * einfo.ads (Component_Bit_Offset): Fix documentation.
7601 * sem_ch13.adb (Check_Record_Representation_Clause): Skip check
7602 on record holes for components with unknown compile-time offsets.

7607 * g-locfil.ads: Minor comment fix.
7609 2017-01-13 Bob Duff <duff@adacore.com>
7611 * binde.adb (Elab_New): New elaboration order algorithm
7612 that is expected to cause fewer ABE issues. This is a work in
7613 progress. The new algorithm is currently disabled, and can be
7614 enable by the -dp switch, or by modifying the Do_Old and Do_New
7615 etc. flags and rebuilding. Experimental code is included to
7616 compare the results of the old and new algorithms.
7617 * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
7618 can have multiple of these tables, so the old and new algorithms
7620 * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
7621 parameter of type array. This avoids the global variable, and
7622 allows bounds checking (which is normally defeated by the tables
7623 packages). It also ensures that the Elab_Order is read-only
7625 * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
7626 subprograms that need it, as above.
7627 * debug.adb: Document new -dp switch. Modify doc of old -do
7629 * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
7630 and Bindgen. Move writing of closure (-R and -Ra switches)
7631 to Binde; that's more convenient.
7633 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7635 * sem_ch6.adb (Analyze_Expression_Function): If the expression
7636 function is a completion, all entities referenced in the
7637 expression are frozen. As a consequence, a reference to an
7638 uncompleted private type from an enclosing scope is illegal.
7640 2017-01-13 Javier Miranda <miranda@adacore.com>
7642 * sem_ch6.adb (Freeze_Expr_Types): New subprogram.
7643 (Analyze_Subprogram_Body_Helper): At the occurrence of an
7644 expression function declaration that is a completion, its
7645 expression causes freezing (AI12-0103).
7647 2017-01-13 Vadim Godunko <godunko@adacore.com>
7649 * a-coinho-shared.adb: Fix memory leaks in Constant_Reference and

7658 * exp_ch3.adb (Default_Initialize_Object): Do not default
7659 initialize an object when it is of a task type and restriction
7660 No_Tasking is in effect because the initialization is obsolete.
7661 * exp_ch9.adb (Build_Master_Entity): Do not generate a master when
7662 restriction No_Tasking is in effect.
7663 (Build_Master_Renaming): Do not rename a master when restriction
7664 No_Tasking is in effect.
7666 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7668 * sem_aggr.adb (Resolve_Array_Aggregate): The code that verifies
7669 the legality of An others clause applies as well to a choice in
7670 an Iterated_component_ association.
7671 (Resolve_Iterated_Component_Association): An others choice
7673 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): An
7674 Iterated_Component_Association is not static.
7676 2017-01-13 Hristian Kirtchev <kirtchev@adacore.com>
7678 * exp_ch3.adb (Freeze_Type): Mark the Ghost mode as set in case
7679 control is passed to the expresion handler before the new mode

7682 Analyze_Subprogram_Instantiation): Mark the Ghost mode as set
7683 in case control is passed to the expresion handler before the

7693 * inline.adb: Minor reformatting and typo fix.
7695 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7697 * sem_util.ads, sem_util.adb (Choice_List): Move function here
7698 from sem_aggr.adb, for use elsewhere.
7699 * sem_ch3.adb (Analyze_Object_Declaration): Use Choice_List.
7700 * sem_aggr.adb (Resolve_Array_Aggregate): Remove
7701 Iterated_Component_Present.
7702 * exp_aggr.adb: Use Choice_List throughout, to handle
7703 Iterated_Component_Associations.
7704 (Gen_Loop): Generate proper loop for an
7705 Iterated_Component_Association: loop variable has the identifier
7706 of the original association. Generate a loop even for a single
7707 component choice, in order to make loop parameter visible in
7709 (Flatten): An Iterated_Component_Association is not static.
7711 2017-01-13 Yannick Moy <moy@adacore.com>
7713 * exp_ch4.adb (Expand_N_Op_Expon): Ensure that the value of
7714 float exponentiation for statically known small negative values
7715 is the reciprocal of the exponentiation for the opposite value
7717 * s-exnllf.adb (Exn_Float, Exn_Long_Float, Exn_Long_Long_Float):
7718 Ensure that the value of float exponentiation for negative values
7719 is the reciprocal of the exponentiation for the opposite value

7728 expression in delay statement as OK for volatile context.
7730 2017-01-13 Ed Schonberg <schonberg@adacore.com>
7732 * sem_aggr.adb (Resolve_Array_Aggregate): In normal compilation
7733 mode a choice that is a subtype with a static predicate is
7734 replaced by the values it covers. This transformation must not
7735 be performed in ASIS mode, to preserve the source for analysis.
7737 2017-01-13 Justin Squirek <squirek@adacore.com>
7739 * nlists.ads: Correct minor typo.
7741 2017-01-13 Gary Dismukes <dismukes@adacore.com>

7748 Iterated_Component_Association is a named association in an
7750 * sem_aggr.adb (Resolve_Iterated_Component_Association): New
7751 procedure, subsidiary of Resolve_Array_Aggregate, to analyze
7752 and resolve the discrete choices and the expression of the
7754 * sinfo.adb, sinfo.ads: In analogy with N_Component_Association,
7755 Loop_Actions and Box_Present are attributes of
7756 N_Iterated_Component_Association nodes. Box_Present is always
7758 * sprint.adb (Sprint_Node): An Iterated_Component_Association
7759 has a Discrete_Choices list, as specified in the RM. A
7760 Component_Association for aggregate uses instead a Choices list.
7761 We have to live with this small inconsistency because the new
7762 construct also has a defining identifier, and there is no way
7763 to merge the two node structures.
7765 2017-01-13 Yannick Moy <moy@adacore.com>
7767 * inline.adb (Remove_Aspects_And_Pragmas): Add Unused to the
7768 list of pragmas to remove. Remove pragmas from the list of

7774 * sem_ch3.adb (Resolve_Aspects): New procedure, subsidiary of
7775 Analyze_Declarations, to analyze and resolve the expressions of
7776 aspect specifications in the current declarative list, so that
7777 the expressions have proper entity and type info. This is needed
7778 for ASIS when there is no subsequent expansion to generate this
7779 semantic information.
7780 * sem_ch13.adb (Check_Aspect_At_End_Of_Declarations): Use Etype of
7781 original expression, to suppress cascaded errors when expression
7782 has been constant-folded.
7783 (Resolve_Aspect_Expressions, Resolve_Name): Preserve entities in
7784 ASIS mode, because there is no subsequent expansion to decorate

7789 * inline.adb, inline.ads (Call_Can_Be_Inlined_In_GNATprove_Mode):
7790 New function to detect when a call may be inlined or not in
7792 (Expand_Inlined_Call): Ensure that a temporary
7793 is always created in the cases where a type conversion may be
7794 needed on an input parameter in GNATprove mode, so that GNATprove
7795 sees the check to perform.
7796 * sem_res.adb (Resolve_Call): In GNATprove mode, skip inlining
7797 when not applicable due to actual requiring type conversion
7798 with possible check but no temporary value can be copied for
7799 GNATprove to see the check.
