617 comment about the memset case.
619 2018-05-30 Bob Duff <duff@adacore.com>
621 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
622 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
623 We need to analyze it as part of analyzing the block, so that if the
624 call to Element that initializes Elmt_Decl returns on the secondary
625 stack, the block will ss_mark/ss_release. This block is inside the
626 loop; we don't want to leak memory until the loop exits. The purpose
627 of analyzing Elmt_Decl first was to catch the error of modifying it,
628 which is illegal because it's a loop parameter. The above causes us to
629 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
630 it on the Element entity, so we end up with an E_Variable node with the
632 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
633 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
634 parameter not allowed" error if Is_Loop_Parameter.
635 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
636 trigger the call to Diagnose_Non_Variable_Lhs.

652 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
653 a package body that is a compilation unit may contain blocks that
654 declare local subprograms. In Subprogram_Unnesting Mode such
655 subprograms must be handled as nested inside the (implicit) elaboration
656 procedure that executes that statement part. To handle properly uplevel
657 references we construct that subprogram explicitly, to contain blocks
658 and inner subprograms, The statement part of the compilation unit
659 becomes a call to this subprogram. This is only done if blocks are
660 present in the statement list of the body.

1040 back and forth between the fixed point type and a floating point type.
1042 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1044 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1047 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1049 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1050 replaced, if any; all callers changed.
1051 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1052 constant with private view so we take the address of that entity.
1053 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1054 any; all callers changed. Handle N_Indexed_Component like
1055 N_Attribute_Reference. Add N_Type_Conversion case.
1056 (Visit_Node): Indexed references can be uplevel if the type isn't
1058 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1059 been relocated, set first_named pointer in original node as well.

1063 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1064 association with a range or a set of discrete choices, rather than

1080 unnecessary use of 'Unrestricted_Access.
1082 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1084 * repinfo.adb (Expr_Value_S): New routine.
1085 (List_Linker_Section): Properly extract the value of the section
1088 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1090 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1091 description of the -D binder switch to reflect current usage.

1119 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1121 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1122 the declarations of single concurrent types because they fall in the
1123 category of full type and object declarations.
1125 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>

1151 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1152 end with the linker section, if any.
1153 (List_Entities): Do not output the linker section for record types,
1154 array types and variables.
1155 (Print_Expr): Factor out common processing for unary operators and
1156 special values. Adjust and reorder the various cases.
1157 (List_Object_Info): End with the linker section, if any.
1158 (List_Record_Info): Likewise.
1159 (List_Type_Info): Do not start with a blank line.
1161 2018-05-25 Nicolas Roche <roche@adacore.com>

1164 that the result will be either -infinite or +infinite.

1173 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1175 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1176 of a fixed point type and the parent is a multiplying operation,
1177 resolve the operand with its own type because the context will impose a
1178 resulting type on the result of the multiplication by means of
1179 approriate conversion.
1181 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1183 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1184 the in-place initialization aggregate created for pragmas
1185 Initialize_Scalars or Normalize_Scalars is performed with checks
1188 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1190 * exp_aggr.adb (Convert_To_Positional): Bump default for
1191 Max_Others_Replicate to 32. Update comments.

1212 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1214 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1215 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1216 into three distring cases rather than in one loop which attempts to
1217 handle all three cases. This rewrite eliminates an issue where the last
1218 frame of the stack cannot be freed, thus causing the memory range of a
1219 new frame to approach the overflow point of the memory index type.
1220 Since the overflow is logically treated as a
1221 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1222 (SS_Allocate_Static): New routine. The routine factorizes the static
1223 secondary stack-related code from the former SS_Allocate.
1225 2018-05-25 Sergey Rybin <rybin@adacore.com>

1232 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1233 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1234 is created when the proper body of the stub is analyzed.
1235 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1236 is the proper body of a subunit, the cloned body must be inserted in
1237 the declarative list that contains the stub.
1239 2018-05-25 Justin Squirek <squirek@adacore.com>
1241 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1242 generate code for 6.5(8-10) so that we don't get an assertion error
1243 when dealing with an incomplete return type.
1245 2018-05-25 Arnaud Charlet <charlet@adacore.com>

1276 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1277 Validate_Derived_Type_Instance, to verify that all interfaces
1278 implemented by the formal type are also implemented by the actual. The
1279 verification is complicated when an interface of the formal is declared
1280 in a generic unit and the actual is declared in an instance of it.
1281 There is currently no mechanism to relate an interface declared within
1282 a generic to the corresponding interface in an instance, so we must
1283 traverse the list of interfaces of the actual, looking for a name
1284 match, and verifying that that interface is declared in an instance.
1286 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1288 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1289 assertions; replace function versions of Next_Formal/Next_Actual with

1355 in loops at the library level.
1357 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1359 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1360 declaration is inserted into the tree and analyzed at that point, so
1361 should not be reinserted when the body is constructed. Inside a
1362 generic, ensure that the body is not inserted twice in the tree.

1854 iteration of an Ada2012 loop is performed to determine the type of the

2518 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
2520 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2521 delegate the secondary stack management when there is no suitable
2522 transient context, and the transient scope was intended to manage the
2523 secondary stack because this causes premature reclamation. Change the
2524 transient scope creation logic by special casing assignment statements
2525 of controlled components for type initialization procedures.
2526 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
2527 the comment on usage.
2528 (Find_Transient_Context): Change the initinte loop into a while loop.
2529 Iterations schemes and iterator specifications are not valid transient
2530 contexts because they rely on special processing. Assignment statements
2531 are now treated as a normal transient context, special cases are
2532 handled by the caller. Add special processing for pragma Check.
2533 (Is_OK_Construct): Removed. Its functionality has been merged in
2534 routine Find_Transient_Context.
2535 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
2536 retrieve the subprogram being invoked. Use a more accurate predicate
2537 (Requires_Transient_Scope) to determine that the function will emply
2538 the secondary stack.

2740 suitable construct to wrap, and the transient scope was intended to
2741 manage the secondary stack.
2742 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2743 is a valid boundary for a transient expression which comes from the
2744 statements of the alternative, otherwise alternatives cannot be
2745 wrapped. Assignments of controlled objects which have controlled
2746 actions suppressed now stop the traversal as there is no point in
2747 looking for an enclosing construct. Add several N_xxx_Body choices to
2748 the termination conditions for completeness.

2755 (Resolve_Actuals): Account for additional cases where finalization
2756 actions are required by utilizing predicate Needs_Finalization rather
2758 (Resolve_Call): Type initialization procedures can now utilize
2759 transient scopes to manage the secondary stack, thus preventing leaks
2760 during initialization. Remove the previous kludgy algorithm which
2761 attempts to manage the secondary stack at the object creation site.

2894 with a primitive_wrapper, verify that the updated inherited expression
2895 does not contain an internal call to a protected function. This
2896 completes the implementation of AI12-0166.

2944 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2945 Secondary_Stack_Size handling as a pragma is now generated for the
2946 corresponding aspect instead of an attribute. Pragma expression is
2947 relocated instead of evaluated. Discriminant of the corresponding
2948 record type is referenced rather than the type discriminant.
2949 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2950 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2951 * sem_ch13.adb (Analyze_One_Aspect): Transform
2952 Aspect_Secondary_Stack_Size into a pragma instead of an attribute

2973 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2974 analysis on a copy of the expression with a copy of the index variable,
2975 because full expansion will rewrite construct into a loop with the
2976 original loop variable.
2977 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2978 expression is an iterated component association. Full analysis takes
2979 place when construct is rewritten as a loop.
2980 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2981 is not safe for in-place assignment.
