537 * snames.ads-tmpl: Move definition of Name_Max_Entry_Queue_Depth so
538 that it can be processed as a pragma in addition to a restriction and
539 add an entry for the pragma itself.
541 2018-05-30 Ed Schonberg <schonberg@adacore.com>
543 * freeze.adb (Freeze_Object_Declaration): A pragma Thread_Local_Storage
544 is now legal on a variable of composite type initialized with an
545 aggregate that is fully static and requires no elaboration code.
546 * exp_aggr.adb (Convert_To_Positional): Recognize additional cases of
547 nested aggregates that are compile-time static, so they can be used to
548 initialize variables declared with Threqd_Local_Storage.

636 comment about the memset case.
638 2018-05-30 Bob Duff <duff@adacore.com>
640 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
641 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
642 We need to analyze it as part of analyzing the block, so that if the
643 call to Element that initializes Elmt_Decl returns on the secondary
644 stack, the block will ss_mark/ss_release. This block is inside the
645 loop; we don't want to leak memory until the loop exits. The purpose
646 of analyzing Elmt_Decl first was to catch the error of modifying it,
647 which is illegal because it's a loop parameter. The above causes us to
648 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
649 it on the Element entity, so we end up with an E_Variable node with the
651 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
652 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
653 parameter not allowed" error if Is_Loop_Parameter.
654 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
655 trigger the call to Diagnose_Non_Variable_Lhs.

659 * checks.adb (Apply_Scalar_Range_Check):
660 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of

669 2018-05-30 Ed Schonberg <schonberg@adacore.com>
671 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
672 a package body that is a compilation unit may contain blocks that
673 declare local subprograms. In Subprogram_Unnesting Mode such
674 subprograms must be handled as nested inside the (implicit) elaboration
675 procedure that executes that statement part. To handle properly uplevel
676 references we construct that subprogram explicitly, to contain blocks
677 and inner subprograms, The statement part of the compilation unit
678 becomes a call to this subprogram. This is only done if blocks are
679 present in the statement list of the body.

691 for subprogram instantiations to enter callable entity into Subp table.

1040 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1042 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1043 component type, do not expand array equality using the unconstrained
1044 base type, except for the case where the bounds of the type depend on a

1049 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1050 access-to-subprogram types, to indicate that an indirect call through
1051 such a type requires an activation record when compiling for LLVM.
1052 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1054 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1056 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1057 when bounds of fixed type are static, to remove some spuerfluous
1058 implicit conversions and provide an accurate result when converting
1059 back and forth between the fixed point type and a floating point type.
1061 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1063 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1066 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1068 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1069 replaced, if any; all callers changed.
1070 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1071 constant with private view so we take the address of that entity.
1072 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1073 any; all callers changed. Handle N_Indexed_Component like
1074 N_Attribute_Reference. Add N_Type_Conversion case.
1075 (Visit_Node): Indexed references can be uplevel if the type isn't
1077 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1078 been relocated, set first_named pointer in original node as well.

1082 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1083 association with a range or a set of discrete choices, rather than
1084 relocating the node. This avoids inconsistencies in the tree when

1099 unnecessary use of 'Unrestricted_Access.
1101 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1103 * repinfo.adb (Expr_Value_S): New routine.
1104 (List_Linker_Section): Properly extract the value of the section
1107 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1109 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1110 description of the -D binder switch to reflect current usage.

1138 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1140 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1141 the declarations of single concurrent types because they fall in the
1142 category of full type and object declarations.
1144 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>

1151 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1152 includes a call to function to which it applies. This may mean an
1153 omission of an attribute reference 'Result, in particular if the
1154 function is pqrameterless.
1156 2018-05-28 Justin Squirek <squirek@adacore.com>

1163 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1164 GNATprove mode, as the order of resolution (low then high) means that

1170 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1171 end with the linker section, if any.
1172 (List_Entities): Do not output the linker section for record types,
1173 array types and variables.
1174 (Print_Expr): Factor out common processing for unary operators and
1175 special values. Adjust and reorder the various cases.
1176 (List_Object_Info): End with the linker section, if any.
1177 (List_Record_Info): Likewise.
1178 (List_Type_Info): Do not start with a blank line.
1180 2018-05-25 Nicolas Roche <roche@adacore.com>
1182 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1183 that the result will be either -infinite or +infinite.

1192 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1194 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1195 of a fixed point type and the parent is a multiplying operation,
1196 resolve the operand with its own type because the context will impose a
1197 resulting type on the result of the multiplication by means of
1198 approriate conversion.
1200 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1202 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1203 the in-place initialization aggregate created for pragmas
1204 Initialize_Scalars or Normalize_Scalars is performed with checks
1207 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1209 * exp_aggr.adb (Convert_To_Positional): Bump default for
1210 Max_Others_Replicate to 32. Update comments.

1231 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1233 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1234 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1235 into three distring cases rather than in one loop which attempts to
1236 handle all three cases. This rewrite eliminates an issue where the last
1237 frame of the stack cannot be freed, thus causing the memory range of a
1238 new frame to approach the overflow point of the memory index type.
1239 Since the overflow is logically treated as a
1240 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1241 (SS_Allocate_Static): New routine. The routine factorizes the static
1242 secondary stack-related code from the former SS_Allocate.
1244 2018-05-25 Sergey Rybin <rybin@adacore.com>
1246 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'

1251 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1252 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1253 is created when the proper body of the stub is analyzed.
1254 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1255 is the proper body of a subunit, the cloned body must be inserted in
1256 the declarative list that contains the stub.
1258 2018-05-25 Justin Squirek <squirek@adacore.com>
1260 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1261 generate code for 6.5(8-10) so that we don't get an assertion error
1262 when dealing with an incomplete return type.
1264 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1266 * pprint.adb (Expression_Name): Strip too long expressions to avoid

1293 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1295 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1296 Validate_Derived_Type_Instance, to verify that all interfaces
1297 implemented by the formal type are also implemented by the actual. The
1298 verification is complicated when an interface of the formal is declared
1299 in a generic unit and the actual is declared in an instance of it.
1300 There is currently no mechanism to relate an interface declared within
1301 a generic to the corresponding interface in an instance, so we must
1302 traverse the list of interfaces of the actual, looking for a name
1303 match, and verifying that that interface is declared in an instance.
1305 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1307 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1308 assertions; replace function versions of Next_Formal/Next_Actual with

1374 in loops at the library level.
1376 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1378 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1379 declaration is inserted into the tree and analyzed at that point, so
1380 should not be reinserted when the body is constructed. Inside a
1381 generic, ensure that the body is not inserted twice in the tree.

1873 iteration of an Ada2012 loop is performed to determine the type of the

2514 (Uninstall_Discriminants_And_Pop_Scope): Same as above.
2515 * sem_util.adb (New_Copy_Tree): Same as above.
2516 * sem_ch7.adb (Generate_Parent_References): Prevent calls to
2517 Has_Discriminant on non-type entities that might happen when the
2518 compiled code has errors.
2519 * sem_ch3.adb (Derived_Type_Declaration): Only call
2520 Set_Has_Discriminant on type entities.
2522 2018-05-21 Arnaud Charlet <charlet@adacore.com>

2534 attribute reference is legal within a generic unit when the prefix is a
2535 formal private type.
2537 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
2539 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2540 delegate the secondary stack management when there is no suitable
2541 transient context, and the transient scope was intended to manage the
2542 secondary stack because this causes premature reclamation. Change the
2543 transient scope creation logic by special casing assignment statements
2544 of controlled components for type initialization procedures.
2545 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
2546 the comment on usage.
2547 (Find_Transient_Context): Change the initinte loop into a while loop.
2548 Iterations schemes and iterator specifications are not valid transient
2549 contexts because they rely on special processing. Assignment statements
2550 are now treated as a normal transient context, special cases are
2551 handled by the caller. Add special processing for pragma Check.
2552 (Is_OK_Construct): Removed. Its functionality has been merged in
2553 routine Find_Transient_Context.
2554 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
2555 retrieve the subprogram being invoked. Use a more accurate predicate
2556 (Requires_Transient_Scope) to determine that the function will emply
2557 the secondary stack.

2758 management of the secondary stack to an enclosing scope if there is no
2759 suitable construct to wrap, and the transient scope was intended to
2760 manage the secondary stack.
2761 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2762 is a valid boundary for a transient expression which comes from the
2763 statements of the alternative, otherwise alternatives cannot be
2764 wrapped. Assignments of controlled objects which have controlled
2765 actions suppressed now stop the traversal as there is no point in
2766 looking for an enclosing construct. Add several N_xxx_Body choices to
2767 the termination conditions for completeness.

2769 and the associated comment on usage.

2774 (Resolve_Actuals): Account for additional cases where finalization
2775 actions are required by utilizing predicate Needs_Finalization rather
2777 (Resolve_Call): Type initialization procedures can now utilize
2778 transient scopes to manage the secondary stack, thus preventing leaks
2779 during initialization. Remove the previous kludgy algorithm which
2780 attempts to manage the secondary stack at the object creation site.

2909 primitive_wrappers that correspond to explicit operations that override
2910 an interface primitive.
2911 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2912 operation to which the class-wide expression applies is a protected op.
2913 with a primitive_wrapper, verify that the updated inherited expression
2914 does not contain an internal call to a protected function. This
2915 completes the implementation of AI12-0166.

2928 (Is_Implicit_With_Clause): New routine.
2929 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2930 confusion with the with clause attribute by the same name.

2942 which marks implicit with clauses as related to an instantiation.
2943 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2944 (Parent_With): New routine.

2961 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2963 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2964 Secondary_Stack_Size handling as a pragma is now generated for the
2965 corresponding aspect instead of an attribute. Pragma expression is
2966 relocated instead of evaluated. Discriminant of the corresponding
2967 record type is referenced rather than the type discriminant.
2968 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2969 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2970 * sem_ch13.adb (Analyze_One_Aspect): Transform
2971 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2972 because the attribute does not have visibility on a task type's

2992 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2993 analysis on a copy of the expression with a copy of the index variable,
2994 because full expansion will rewrite construct into a loop with the
2995 original loop variable.
2996 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2997 expression is an iterated component association. Full analysis takes
2998 place when construct is rewritten as a loop.
2999 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3000 is not safe for in-place assignment.
