586 2018-05-31 Ed Schonberg <schonberg@adacore.com>
588 * exp_unst.ads, exp_unst.adb (In_Synchronized_Unit): New predicate to
589 mark subprograms that cannot be eliminated because they must be treated

591 and protected operations.
593 2018-05-31 Ed Schonberg <schonberg@adacore.com>
595 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
596 Convert all operands of the generated code to Standard.Unsigned, to
597 prevent spurious visibility errors. This is needed when the generated

609 if the local raise statement includes a string expression. This
610 expression might be picked up by an outer handler or discarded, but
611 plays no role in this transformation.
613 2018-05-30 Hristian Kirtchev <kirtchev@adacore.com>

644 is now legal on a variable of composite type initialized with an
645 aggregate that is fully static and requires no elaboration code.
646 * exp_aggr.adb (Convert_To_Positional): Recognize additional cases of
647 nested aggregates that are compile-time static, so they can be used to
648 initialize variables declared with Threqd_Local_Storage.

662 (Start_Search): Modify to use Start_Search_Internal
663 (Start_Search_Internal): Add to break out an extra flag for searching
664 case insensative due to the potential for directories within the same
665 OS to allow different casing schemes.
666 * sysdep.c (__gnat_name_case_equivalence): Add as a default fallback
667 for when the more precise solution fails.

725 * sem_ch3.adb (Access_Subprogram_Declaration): The flag
726 Needs_Activation_Record is only needed on a subprogram type, not on a

729 component type are anonymous access to subprograms, use the component
730 type to obtain the proper value of Needs_Activation_Record flag for the

735 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>: Add
736 comment about the memset case.
738 2018-05-30 Bob Duff <duff@adacore.com>
740 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
741 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
742 We need to analyze it as part of analyzing the block, so that if the
743 call to Element that initializes Elmt_Decl returns on the secondary
744 stack, the block will ss_mark/ss_release. This block is inside the
745 loop; we don't want to leak memory until the loop exits. The purpose
746 of analyzing Elmt_Decl first was to catch the error of modifying it,
747 which is illegal because it's a loop parameter. The above causes us to
748 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
749 it on the Element entity, so we end up with an E_Variable node with the
751 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
752 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
753 parameter not allowed" error if Is_Loop_Parameter.
754 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
755 trigger the call to Diagnose_Non_Variable_Lhs.
757 2018-05-30 Arnaud Charlet <charlet@adacore.com>
759 * checks.adb (Apply_Scalar_Range_Check):
760 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
761 range values for System.Priority in CodePeer mode since the actual
762 target compiler may provide a wider range.
764 2018-05-30 Ed Schonberg <schonberg@adacore.com>
766 * exp_unst.adb: Search specification of main unit as well, for
769 2018-05-30 Ed Schonberg <schonberg@adacore.com>
771 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
772 a package body that is a compilation unit may contain blocks that
773 declare local subprograms. In Subprogram_Unnesting Mode such
774 subprograms must be handled as nested inside the (implicit) elaboration
775 procedure that executes that statement part. To handle properly uplevel
776 references we construct that subprogram explicitly, to contain blocks
777 and inner subprograms, The statement part of the compilation unit
778 becomes a call to this subprogram. This is only done if blocks are
779 present in the statement list of the body.
781 2018-05-30 Bob Duff <duff@adacore.com>
783 * exp_ch7.adb: Minor comment fix.
785 2018-05-30 Ed Schonberg <schonberg@adacore.com>

788 that have no corresponding body and appear as attributes of the
789 corresponding wrapper package declaration.
790 (Register_Subprogram): New subprogram, used for subprogram bodies and
791 for subprogram instantiations to enter callable entity into Subp table.
793 2018-05-30 Hristian Kirtchev <kirtchev@adacore.com>
795 * libgnat/s-secsta.adb: Reimplement the secondary stack support.
796 * libgnat/s-secsta.ads: Update the documentation of all routines in the
797 public part of the package. Reimplement the private part of the
798 package to account for the new secondary stack structure. Add types
799 and subprograms for testing purposes. Add several documentation

849 with a derivation of an untagged private type whose full view is a
850 tagged type. In such case, collecting the list of primitives we may
851 find two equality primitives: one associated with the untagged private

853 remove from the returned list this latter one).

1052 * lib-writ.adb (Write_ALI): Cleanup: avoid use of global var; call new
1054 * libgnat/s-casuti.ads, libgnat/s-casuti.adb (To_Upper, To_Lower,
1055 To_Mixed): New functions.
1056 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly
1057 allows both '\' and '/' on Windows.
1059 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1061 * repinfo.ads: Minor fixes and tweaks in comments.

1085 * exp_unst.adb (Visit_Node): For indexed components and attribute
1086 references, examine index expressions or associated expressions as well
1087 to record uplevel references.
1088 (Vist_Node): For function and procedure calls, if a formal is an
1089 unconstrained array and the actual is constrained, check whether bounds
1090 of actual have uplevel references.
1092 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1094 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1095 they can appear as components of activation records.

1101 * exp_ch4.adb (Expand_Composite_Equality): Compute whether the size
1102 depends on a discriminant manually instead of using the predicate
1103 Size_Depends_On_Discriminant in the array type case.
1105 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1107 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1108 discriminant constraints as well.
1109 (Visit_Node): For a selected component, check type of prefix, as is
1110 done for indexed components and slices.
1112 2018-05-28 Javier Miranda <miranda@adacore.com>
1114 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1115 value when converting a float value to a fixed-point value. This is
1116 required for CCG because it handles fixed-point types by means of
1117 unsigned integer type variables. The range check is now performed using
1118 the integer value stored in this temporary.
1120 2018-05-28 Yannick Moy <moy@adacore.com>
1122 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1133 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
1134 Sem_Disp.Find_Dispatching_Type.
1135 (Is_Overriding_Subprogram): Instance of
1136 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.

1138 with Sem_Disp.Find_Dispatching_Type.
1140 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1142 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1143 component type, do not expand array equality using the unconstrained
1144 base type, except for the case where the bounds of the type depend on a
1147 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1149 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1150 access-to-subprogram types, to indicate that an indirect call through
1151 such a type requires an activation record when compiling for LLVM.
1152 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1154 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1156 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1157 when bounds of fixed type are static, to remove some spuerfluous
1158 implicit conversions and provide an accurate result when converting
1159 back and forth between the fixed point type and a floating point type.
1161 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1163 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1166 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1168 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1169 replaced, if any; all callers changed.
1170 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1171 constant with private view so we take the address of that entity.
1172 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1173 any; all callers changed. Handle N_Indexed_Component like
1174 N_Attribute_Reference. Add N_Type_Conversion case.
1175 (Visit_Node): Indexed references can be uplevel if the type isn't
1177 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1178 been relocated, set first_named pointer in original node as well.
1180 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1182 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1183 association with a range or a set of discrete choices, rather than
1184 relocating the node. This avoids inconsistencies in the tree when
1185 handling nested subprograms with uplevel references for LLVM.

1199 unnecessary use of 'Unrestricted_Access.
1201 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1203 * repinfo.adb (Expr_Value_S): New routine.

1207 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1209 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1210 description of the -D binder switch to reflect current usage.
1211 * gnat_ugn.texi: Regenerate.
1213 2018-05-28 Gary Dismukes <dismukes@adacore.com>

1238 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1240 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1241 the declarations of single concurrent types because they fall in the
1242 category of full type and object declarations.
1244 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1246 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1249 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1251 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1252 includes a call to function to which it applies. This may mean an
1253 omission of an attribute reference 'Result, in particular if the
1254 function is pqrameterless.
1256 2018-05-28 Justin Squirek <squirek@adacore.com>

1263 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1264 GNATprove mode, as the order of resolution (low then high) means that

1268 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1270 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1271 end with the linker section, if any.
1272 (List_Entities): Do not output the linker section for record types,
1273 array types and variables.
1274 (Print_Expr): Factor out common processing for unary operators and
1275 special values. Adjust and reorder the various cases.
1276 (List_Object_Info): End with the linker section, if any.
1277 (List_Record_Info): Likewise.
1278 (List_Type_Info): Do not start with a blank line.
1280 2018-05-25 Nicolas Roche <roche@adacore.com>
1282 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1283 that the result will be either -infinite or +infinite.
1285 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1287 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

1289 Expand range of type to match the address space of the target.
1290 (Task_Storage_Size): Remove unused type.
1292 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1294 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1295 of a fixed point type and the parent is a multiplying operation,
1296 resolve the operand with its own type because the context will impose a
1297 resulting type on the result of the multiplication by means of
1298 approriate conversion.
1300 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1302 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1303 the in-place initialization aggregate created for pragmas
1304 Initialize_Scalars or Normalize_Scalars is performed with checks
1307 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1309 * exp_aggr.adb (Convert_To_Positional): Bump default for
1310 Max_Others_Replicate to 32. Update comments.
1311 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1312 (No_File_Info_Cache): Initialize separately.

1317 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
1318 test when the left operand is a class-wide interface and the right

1320 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
1323 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1325 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
1326 in an others clause to prevent visibility issues with the generated

1329 (Check_Static_Component): Ditto.
1331 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1333 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1334 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1335 into three distring cases rather than in one loop which attempts to
1336 handle all three cases. This rewrite eliminates an issue where the last
1337 frame of the stack cannot be freed, thus causing the memory range of a
1338 new frame to approach the overflow point of the memory index type.
1339 Since the overflow is logically treated as a
1340 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1341 (SS_Allocate_Static): New routine. The routine factorizes the static
1342 secondary stack-related code from the former SS_Allocate.
1344 2018-05-25 Sergey Rybin <rybin@adacore.com>
1346 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1347 option for gnatelim.
1349 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1351 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1352 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1353 is created when the proper body of the stub is analyzed.
1354 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1355 is the proper body of a subunit, the cloned body must be inserted in
1356 the declarative list that contains the stub.
1358 2018-05-25 Justin Squirek <squirek@adacore.com>
1360 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1361 generate code for 6.5(8-10) so that we don't get an assertion error
1362 when dealing with an incomplete return type.
1364 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1366 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1367 carrying very large strings.

1371 * switch-b.adb (Scan_Binder_Switches): binder switch -Q accepts Natural

1393 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1395 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1396 Validate_Derived_Type_Instance, to verify that all interfaces
1397 implemented by the formal type are also implemented by the actual. The
1398 verification is complicated when an interface of the formal is declared
1399 in a generic unit and the actual is declared in an instance of it.
1400 There is currently no mechanism to relate an interface declared within
1401 a generic to the corresponding interface in an instance, so we must
1402 traverse the list of interfaces of the actual, looking for a name
1403 match, and verifying that that interface is declared in an instance.
1405 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1407 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1408 assertions; replace function versions of Next_Formal/Next_Actual with
1409 their procedural versions (which are more concise).

1420 for incremental looping. Remove references to Rel_Time and
1421 Relative_Timed_Wait.

1443 boolean type with convention C.
1444 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
1445 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable
1446 FOREIGN and use it throughout the function.
1447 <E_Enumeration_Type>: Set precision 1 on boolean types with foreign
1449 <E_Enumeration_Subtype>: Likewise for subtypes.
1450 <E_Record_Type>: Force the size of a storage unit on empty classes.
1451 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
1452 boolean types with precision 1 if the size is the expected one.

1470 prefixes of array attributes, to prefixes that are entity names whose
1471 type is constrained.
1472 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
1473 subprogram, as itype created for loops in pre/postcondition may appear
1474 in loops at the library level.
1476 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1478 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1479 declaration is inserted into the tree and analyzed at that point, so
1480 should not be reinserted when the body is constructed. Inside a
1481 generic, ensure that the body is not inserted twice in the tree.

2518 the configuration level, and on the initial declaration of a unit.
2519 Other placements are either flagged as illegal, or ignored.
2520 (Check_Duplicate_Elaboration_Checks_Pragma): New routine.
2521 (Ignore_Elaboration_Checks_Pragma): New routine.

2528 2018-05-21 Olivier Hainque <hainque@adacore.com>
2530 * libgnat/s-trasym__dwarf.adb (Executable_Name): Return argv[0] instead
2531 of empty string when argv[0] couldn't be found on PATH.
2532 (Enable_Cache): Raise Program_Error instead of attempting a null
2533 pointer dereference when the Exec_Module initialization failed.

2552 * sem_util.adb (Find_Simple_Properties): New routine.
2553 (Is_Enabled_External_Property): New routine.
2554 (State_Has_Enabled_Property): Reimplemented. The two flavors of option
2555 External have precedence over option Synchronous when determining
2556 whether a property is in effect.
2558 2018-05-21 Yannick Moy <moy@adacore.com>

2575 * libgnat/s-dwalin.ads (Dwarf_Context): Change type of Load_Address to
2576 Address, and type of Low, High to Storage_Offset.
2577 (Low): Rename as Low_Address and convey that the return value is a
2578 runtime reference accounting for a load address.
2579 * libgnat/s-dwalin.adb (Read_Aranges_Entry): Adjust to the
2580 address/offset type changes.
2581 (Aranges_Lookup): Likewise.

2606 lm.l_addr as the Load_Address to Add_Module_To_Cache.
2608 2018-05-21 Piotr Trojanek <trojanek@adacore.com>
2610 * einfo.adb (Has_Discriminants): Stronger assertion.

2633 * sem_attr.adb (Analyze_Attribute, case Scalar_Storage_Order): The
2634 attribute reference is legal within a generic unit when the prefix is a
2635 formal private type.
2637 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
2639 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2640 delegate the secondary stack management when there is no suitable
2641 transient context, and the transient scope was intended to manage the
2642 secondary stack because this causes premature reclamation. Change the
2643 transient scope creation logic by special casing assignment statements
2644 of controlled components for type initialization procedures.
2645 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
2646 the comment on usage.
2647 (Find_Transient_Context): Change the initinte loop into a while loop.
2648 Iterations schemes and iterator specifications are not valid transient
2649 contexts because they rely on special processing. Assignment statements
2650 are now treated as a normal transient context, special cases are
2651 handled by the caller. Add special processing for pragma Check.
2652 (Is_OK_Construct): Removed. Its functionality has been merged in
2653 routine Find_Transient_Context.
2654 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
2655 retrieve the subprogram being invoked. Use a more accurate predicate
2656 (Requires_Transient_Scope) to determine that the function will emply
2657 the secondary stack.

2859 suitable construct to wrap, and the transient scope was intended to
2860 manage the secondary stack.
2861 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2862 is a valid boundary for a transient expression which comes from the
2863 statements of the alternative, otherwise alternatives cannot be

2865 actions suppressed now stop the traversal as there is no point in
2866 looking for an enclosing construct. Add several N_xxx_Body choices to
2867 the termination conditions for completeness.

2875 actions are required by utilizing predicate Needs_Finalization rather
2877 (Resolve_Call): Type initialization procedures can now utilize
2878 transient scopes to manage the secondary stack, thus preventing leaks
2879 during initialization. Remove the previous kludgy algorithm which
2880 attempts to manage the secondary stack at the object creation site.

2928 in the generic unless they reference a formal subprogram. Clarify

3026 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3027 either implicitly or explicitly withed.
3028 (Is_Implicit_With_Clause): New routine.
3029 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3030 confusion with the with clause attribute by the same name.
3031 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3032 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3033 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3034 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3036 (Implicit_With_On_Parent): Mark the with clause as generated for a
3038 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3039 instantiation are no longer marked as Implicit_With_From_Instantiation
3040 because they are already marked as implicit.
3041 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3042 which marks implicit with clauses as related to an instantiation.
3043 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3044 (Parent_With): New routine.
3045 (Set_Implicit_With_From_Instantiation): Removed.
3046 (Set_Parent_With): New routine.
3047 * sinfo.ads: Update the documentation of attribute Implicit_With.
3048 Remove attribute Implicit_With_From_Instantiation along with
3049 occurrences in nodes. Add attribute Parent_With along with occurrences
3051 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
3052 (Parent_With): New routine along with pragma Inline.
3053 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
3054 (Set_Parent_With): New routine along with pragma Inline.
3056 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3058 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3059 entity when the enclosing construct is a body.
3061 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3063 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3064 Secondary_Stack_Size handling as a pragma is now generated for the
3065 corresponding aspect instead of an attribute. Pragma expression is
3066 relocated instead of evaluated. Discriminant of the corresponding
3067 record type is referenced rather than the type discriminant.
3068 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3069 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3070 * sem_ch13.adb (Analyze_One_Aspect): Transform
3071 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3072 because the attribute does not have visibility on a task type's
3073 discriminants when the type's definition is expanded.
3074 (Analyze_Attribute_Definition_Clause): Remove handling of
3075 Attribute_Secondary_Stack_Size.
3076 * snames.adb-tmpl, snames.ads-tmpl: Remove
3077 Attribute_Secondary_Stack_Size, no longer used.
3079 2018-01-11 Justin Squirek <squirek@adacore.com>
3081 * sem_ch8.adb: Minor comment fix.
3083 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3085 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3086 individual action because the action may denote a complex expression,
3087 such as a case statement, which in turn may contain additional
3090 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3092 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3093 analysis on a copy of the expression with a copy of the index variable,
3094 because full expansion will rewrite construct into a loop with the
3095 original loop variable.
3096 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3097 expression is an iterated component association. Full analysis takes
3098 place when construct is rewritten as a loop.
3099 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3100 is not safe for in-place assignment.
3101 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3102 entity with no homonym and no other entity in the scope.
3104 2018-01-11 Justin Squirek <squirek@adacore.com>
3106 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3107 message to be printed on the pragma argument identifier.
3109 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3111 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3112 entity of the generated invariant procedure in order to construct a
3113 proper entity chain.
3115 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3117 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3120 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3122 * einfo.ads, einfo.adb (Activation_Record_Component,
3123 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3124 Allow E_Discriminant.
3126 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3128 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3129 for atomic access once the component size is taken into account and
3130 also do it if the component type is Atomic or Volatile_Full_Access.
3132 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3134 * gnatvsn.ads: Bump copyright year.

3151 Alan Hayward <alan.hayward@arm.com>
3152 David Sherwood <david.sherwood@arm.com>
3154 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
3155 polynomial TYPE_VECTOR_SUBPARTS.
