576 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
577 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
578 We need to analyze it as part of analyzing the block, so that if the
579 call to Element that initializes Elmt_Decl returns on the secondary
580 stack, the block will ss_mark/ss_release. This block is inside the
581 loop; we don't want to leak memory until the loop exits. The purpose
582 of analyzing Elmt_Decl first was to catch the error of modifying it,
583 which is illegal because it's a loop parameter. The above causes us to
584 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
585 it on the Element entity, so we end up with an E_Variable node with the

608 a package body that is a compilation unit may contain blocks that
609 declare local subprograms. In Subprogram_Unnesting Mode such
610 subprograms must be handled as nested inside the (implicit) elaboration
611 procedure that executes that statement part. To handle properly uplevel
612 references we construct that subprogram explicitly, to contain blocks
613 and inner subprograms, The statement part of the compilation unit
614 becomes a call to this subprogram. This is only done if blocks are
615 present in the statement list of the body.

1008 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1009 any; all callers changed. Handle N_Indexed_Component like
1010 N_Attribute_Reference. Add N_Type_Conversion case.
1011 (Visit_Node): Indexed references can be uplevel if the type isn't

1074 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1076 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1077 the declarations of single concurrent types because they fall in the
1078 category of full type and object declarations.

1106 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1107 end with the linker section, if any.
1108 (List_Entities): Do not output the linker section for record types,
1109 array types and variables.
1110 (Print_Expr): Factor out common processing for unary operators and
1111 special values. Adjust and reorder the various cases.
1112 (List_Object_Info): End with the linker section, if any.
1113 (List_Record_Info): Likewise.

1128 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1130 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1131 of a fixed point type and the parent is a multiplying operation,
1132 resolve the operand with its own type because the context will impose a
1133 resulting type on the result of the multiplication by means of
1134 approriate conversion.
1136 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1138 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1139 the in-place initialization aggregate created for pragmas
1140 Initialize_Scalars or Normalize_Scalars is performed with checks
1143 2018-05-25 Arnaud Charlet <charlet@adacore.com>

1167 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1169 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1170 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1171 into three distring cases rather than in one loop which attempts to
1172 handle all three cases. This rewrite eliminates an issue where the last
1173 frame of the stack cannot be freed, thus causing the memory range of a
1174 new frame to approach the overflow point of the memory index type.
1175 Since the overflow is logically treated as a
1176 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1177 (SS_Allocate_Static): New routine. The routine factorizes the static
1178 secondary stack-related code from the former SS_Allocate.
1180 2018-05-25 Sergey Rybin <rybin@adacore.com>

1187 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1188 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1189 is created when the proper body of the stub is analyzed.
1190 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1191 is the proper body of a subunit, the cloned body must be inserted in
1192 the declarative list that contains the stub.
1194 2018-05-25 Justin Squirek <squirek@adacore.com>
1196 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1197 generate code for 6.5(8-10) so that we don't get an assertion error
1198 when dealing with an incomplete return type.
1200 2018-05-25 Arnaud Charlet <charlet@adacore.com>

1231 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1232 Validate_Derived_Type_Instance, to verify that all interfaces
1233 implemented by the formal type are also implemented by the actual. The
1234 verification is complicated when an interface of the formal is declared
1235 in a generic unit and the actual is declared in an instance of it.
1236 There is currently no mechanism to relate an interface declared within
1237 a generic to the corresponding interface in an instance, so we must
1238 traverse the list of interfaces of the actual, looking for a name
1239 match, and verifying that that interface is declared in an instance.
1241 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1243 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1244 assertions; replace function versions of Next_Formal/Next_Actual with

1310 in loops at the library level.
1312 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1314 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1315 declaration is inserted into the tree and analyzed at that point, so
1316 should not be reinserted when the body is constructed. Inside a
1317 generic, ensure that the body is not inserted twice in the tree.

2475 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2476 delegate the secondary stack management when there is no suitable
2477 transient context, and the transient scope was intended to manage the

2694 management of the secondary stack to an enclosing scope if there is no
2695 suitable construct to wrap, and the transient scope was intended to
2696 manage the secondary stack.
2697 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2698 is a valid boundary for a transient expression which comes from the
2699 statements of the alternative, otherwise alternatives cannot be
2700 wrapped. Assignments of controlled objects which have controlled
2701 actions suppressed now stop the traversal as there is no point in
2702 looking for an enclosing construct. Add several N_xxx_Body choices to
2703 the termination conditions for completeness.

2705 and the associated comment on usage.

2710 (Resolve_Actuals): Account for additional cases where finalization
2711 actions are required by utilizing predicate Needs_Finalization rather
2713 (Resolve_Call): Type initialization procedures can now utilize
2714 transient scopes to manage the secondary stack, thus preventing leaks
2715 during initialization. Remove the previous kludgy algorithm which
2716 attempts to manage the secondary stack at the object creation site.

2761 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the

2763 because in this case there can be no suspicious arithmetic operations
2764 in the generic unless they reference a formal subprogram. Clarify

2845 primitive_wrappers that correspond to explicit operations that override
2846 an interface primitive.
2847 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2848 operation to which the class-wide expression applies is a protected op.
2849 with a primitive_wrapper, verify that the updated inherited expression
2850 does not contain an internal call to a protected function. This
2851 completes the implementation of AI12-0166.

2863 either implicitly or explicitly withed.
2864 (Is_Implicit_With_Clause): New routine.
2865 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2866 confusion with the with clause attribute by the same name.

2878 which marks implicit with clauses as related to an instantiation.
2879 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2880 (Parent_With): New routine.
2881 (Set_Implicit_With_From_Instantiation): Removed.

2899 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2900 Secondary_Stack_Size handling as a pragma is now generated for the
2901 corresponding aspect instead of an attribute. Pragma expression is
2902 relocated instead of evaluated. Discriminant of the corresponding
2903 record type is referenced rather than the type discriminant.
2904 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2905 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2906 * sem_ch13.adb (Analyze_One_Aspect): Transform
2907 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2908 because the attribute does not have visibility on a task type's

2928 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2929 analysis on a copy of the expression with a copy of the index variable,
2930 because full expansion will rewrite construct into a loop with the
2931 original loop variable.
2932 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2933 expression is an iterated component association. Full analysis takes
2934 place when construct is rewritten as a loop.
2935 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2936 is not safe for in-place assignment.
2937 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
