537 field in relevant nodes: Allocate, Free, and return statements.
539 2018-05-30 Ed Schonberg <schonberg@adacore.com>
541 * exp_unst.adb (Visit_Node): Do not traverse a Component_Association
542 that has not been analyzed, as will be the case for a nested aggregate
543 that is expanded into individual assignments.
545 2018-05-30 Justin Squirek <squirek@adacore.com>
547 * aspects.adb, aspects.ads: Register new aspect.

552 set it to use the same processing as Pragma_Max_Queue_Length.
553 * snames.ads-tmpl: Move definition of Name_Max_Entry_Queue_Depth so
554 that it can be processed as a pragma in addition to a restriction and
555 add an entry for the pragma itself.
557 2018-05-30 Ed Schonberg <schonberg@adacore.com>
559 * freeze.adb (Freeze_Object_Declaration): A pragma Thread_Local_Storage
560 is now legal on a variable of composite type initialized with an
561 aggregate that is fully static and requires no elaboration code.
562 * exp_aggr.adb (Convert_To_Positional): Recognize additional cases of
563 nested aggregates that are compile-time static, so they can be used to
564 initialize variables declared with Threqd_Local_Storage.
565 * doc/gnat_rm/implementation_defined_pragmas.rst: Add documentation on
566 Thread_Local_Storage.
567 * gnat_rm.texi: Regenerate.

578 (Start_Search): Modify to use Start_Search_Internal
579 (Start_Search_Internal): Add to break out an extra flag for searching
580 case insensative due to the potential for directories within the same

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

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

652 comment about the memset case.
654 2018-05-30 Bob Duff <duff@adacore.com>
656 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
657 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
658 We need to analyze it as part of analyzing the block, so that if the
659 call to Element that initializes Elmt_Decl returns on the secondary
660 stack, the block will ss_mark/ss_release. This block is inside the
661 loop; we don't want to leak memory until the loop exits. The purpose
662 of analyzing Elmt_Decl first was to catch the error of modifying it,
663 which is illegal because it's a loop parameter. The above causes us to
664 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
665 it on the Element entity, so we end up with an E_Variable node with the
667 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
668 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
669 parameter not allowed" error if Is_Loop_Parameter.
670 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
671 trigger the call to Diagnose_Non_Variable_Lhs.
673 2018-05-30 Arnaud Charlet <charlet@adacore.com>
675 * checks.adb (Apply_Scalar_Range_Check):
676 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
677 range values for System.Priority in CodePeer mode since the actual
678 target compiler may provide a wider range.

682 * exp_unst.adb: Search specification of main unit as well, for
685 2018-05-30 Ed Schonberg <schonberg@adacore.com>
687 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
688 a package body that is a compilation unit may contain blocks that
689 declare local subprograms. In Subprogram_Unnesting Mode such
690 subprograms must be handled as nested inside the (implicit) elaboration
691 procedure that executes that statement part. To handle properly uplevel
692 references we construct that subprogram explicitly, to contain blocks
693 and inner subprograms, The statement part of the compilation unit
694 becomes a call to this subprogram. This is only done if blocks are
695 present in the statement list of the body.
697 2018-05-30 Bob Duff <duff@adacore.com>

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

711 * libgnat/s-secsta.adb: Reimplement the secondary stack support.
712 * libgnat/s-secsta.ads: Update the documentation of all routines in the
713 public part of the package. Reimplement the private part of the
714 package to account for the new secondary stack structure. Add types
715 and subprograms for testing purposes. Add several documentation

766 tagged type. In such case, collecting the list of primitives we may
767 find two equality primitives: one associated with the untagged private

1030 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1031 value when converting a float value to a fixed-point value. This is
1032 required for CCG because it handles fixed-point types by means of
1033 unsigned integer type variables. The range check is now performed using

1056 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1058 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1059 component type, do not expand array equality using the unconstrained
1060 base type, except for the case where the bounds of the type depend on a

1065 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1066 access-to-subprogram types, to indicate that an indirect call through
1067 such a type requires an activation record when compiling for LLVM.

1070 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1072 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1073 when bounds of fixed type are static, to remove some spuerfluous
1074 implicit conversions and provide an accurate result when converting
1075 back and forth between the fixed point type and a floating point type.
1077 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1079 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1082 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1084 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1085 replaced, if any; all callers changed.
1086 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1087 constant with private view so we take the address of that entity.
1088 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1089 any; all callers changed. Handle N_Indexed_Component like
1090 N_Attribute_Reference. Add N_Type_Conversion case.
1091 (Visit_Node): Indexed references can be uplevel if the type isn't
1093 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1094 been relocated, set first_named pointer in original node as well.

1098 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1099 association with a range or a set of discrete choices, rather than

1115 unnecessary use of 'Unrestricted_Access.
1117 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1119 * repinfo.adb (Expr_Value_S): New routine.
1120 (List_Linker_Section): Properly extract the value of the section
1123 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1125 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1126 description of the -D binder switch to reflect current usage.

1154 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1156 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1157 the declarations of single concurrent types because they fall in the
1158 category of full type and object declarations.
1160 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1162 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1167 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1168 includes a call to function to which it applies. This may mean an
1169 omission of an attribute reference 'Result, in particular if the
1170 function is pqrameterless.
1172 2018-05-28 Justin Squirek <squirek@adacore.com>
1174 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the

1179 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1180 GNATprove mode, as the order of resolution (low then high) means that

1186 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1187 end with the linker section, if any.
1188 (List_Entities): Do not output the linker section for record types,
1189 array types and variables.
1190 (Print_Expr): Factor out common processing for unary operators and
1191 special values. Adjust and reorder the various cases.
1192 (List_Object_Info): End with the linker section, if any.
1193 (List_Record_Info): Likewise.
1194 (List_Type_Info): Do not start with a blank line.
1196 2018-05-25 Nicolas Roche <roche@adacore.com>
1198 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1199 that the result will be either -infinite or +infinite.

1208 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1210 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1211 of a fixed point type and the parent is a multiplying operation,
1212 resolve the operand with its own type because the context will impose a
1213 resulting type on the result of the multiplication by means of
1214 approriate conversion.
1216 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1218 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1219 the in-place initialization aggregate created for pragmas
1220 Initialize_Scalars or Normalize_Scalars is performed with checks
1223 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1225 * exp_aggr.adb (Convert_To_Positional): Bump default for
1226 Max_Others_Replicate to 32. Update comments.

1247 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1249 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1250 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1251 into three distring cases rather than in one loop which attempts to
1252 handle all three cases. This rewrite eliminates an issue where the last
1253 frame of the stack cannot be freed, thus causing the memory range of a
1254 new frame to approach the overflow point of the memory index type.
1255 Since the overflow is logically treated as a
1256 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1257 (SS_Allocate_Static): New routine. The routine factorizes the static
1258 secondary stack-related code from the former SS_Allocate.
1260 2018-05-25 Sergey Rybin <rybin@adacore.com>
1262 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'

1267 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1268 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1269 is created when the proper body of the stub is analyzed.
1270 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1271 is the proper body of a subunit, the cloned body must be inserted in
1272 the declarative list that contains the stub.
1274 2018-05-25 Justin Squirek <squirek@adacore.com>
1276 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1277 generate code for 6.5(8-10) so that we don't get an assertion error
1278 when dealing with an incomplete return type.
1280 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1282 * pprint.adb (Expression_Name): Strip too long expressions to avoid

1309 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1311 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1312 Validate_Derived_Type_Instance, to verify that all interfaces
1313 implemented by the formal type are also implemented by the actual. The
1314 verification is complicated when an interface of the formal is declared
1315 in a generic unit and the actual is declared in an instance of it.
1316 There is currently no mechanism to relate an interface declared within
1317 a generic to the corresponding interface in an instance, so we must
1318 traverse the list of interfaces of the actual, looking for a name
1319 match, and verifying that that interface is declared in an instance.
1321 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1323 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1324 assertions; replace function versions of Next_Formal/Next_Actual with
1325 their procedural versions (which are more concise).

1366 <E_Record_Type>: Force the size of a storage unit on empty classes.
1367 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip

1389 subprogram, as itype created for loops in pre/postcondition may appear
1390 in loops at the library level.
1392 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1394 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1395 declaration is inserted into the tree and analyzed at that point, so
1396 should not be reinserted when the body is constructed. Inside a
1397 generic, ensure that the body is not inserted twice in the tree.

2513 * libgnat/s-dwalin.adb (Is_Inside): Adjust accordingly.
2514 (Set_Load_Address): Likewise.
2515 (Symbolic_Traceback): Likewise.
2517 2018-05-21 Olivier Hainque <hainque@adacore.com>
2519 * libgnat/s-trasym__dwarf.adb (Add_Module_To_Cache): Expect a
2520 Load_Address argument and pass it down to Init_Module.
2521 * libgnat/s-tsmona__linux.adb (Build_Cache_For_All_Modules): Pass
2522 lm.l_addr as the Load_Address to Add_Module_To_Cache.
2524 2018-05-21 Piotr Trojanek <trojanek@adacore.com>
2526 * einfo.adb (Has_Discriminants): Stronger assertion.
2527 (Set_Has_Discriminants): Stronger assertion.
2528 * sem_ch13.adb (Push_Scope_And_Install_Discriminants): Adapt to respect
2529 the stronger assertion on Has_Discriminant.
2530 (Uninstall_Discriminants_And_Pop_Scope): Same as above.
2531 * sem_util.adb (New_Copy_Tree): Same as above.
2532 * sem_ch7.adb (Generate_Parent_References): Prevent calls to
2533 Has_Discriminant on non-type entities that might happen when the
2534 compiled code has errors.
2535 * sem_ch3.adb (Derived_Type_Declaration): Only call
2536 Set_Has_Discriminant on type entities.

2551 formal private type.
2553 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
2555 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2556 delegate the secondary stack management when there is no suitable
2557 transient context, and the transient scope was intended to manage the
2558 secondary stack because this causes premature reclamation. Change the
2559 transient scope creation logic by special casing assignment statements
2560 of controlled components for type initialization procedures.
2561 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
2562 the comment on usage.
2563 (Find_Transient_Context): Change the initinte loop into a while loop.
2564 Iterations schemes and iterator specifications are not valid transient
2565 contexts because they rely on special processing. Assignment statements
2566 are now treated as a normal transient context, special cases are
2567 handled by the caller. Add special processing for pragma Check.
2568 (Is_OK_Construct): Removed. Its functionality has been merged in
2569 routine Find_Transient_Context.
2570 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
2571 retrieve the subprogram being invoked. Use a more accurate predicate
2572 (Requires_Transient_Scope) to determine that the function will emply
2573 the secondary stack.

2775 suitable construct to wrap, and the transient scope was intended to
2776 manage the secondary stack.
2777 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2778 is a valid boundary for a transient expression which comes from the
2779 statements of the alternative, otherwise alternatives cannot be
2780 wrapped. Assignments of controlled objects which have controlled
2781 actions suppressed now stop the traversal as there is no point in
2782 looking for an enclosing construct. Add several N_xxx_Body choices to
2783 the termination conditions for completeness.
2784 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2785 and the associated comment on usage.

2790 (Resolve_Actuals): Account for additional cases where finalization
2791 actions are required by utilizing predicate Needs_Finalization rather
2793 (Resolve_Call): Type initialization procedures can now utilize
2794 transient scopes to manage the secondary stack, thus preventing leaks
2795 during initialization. Remove the previous kludgy algorithm which
2796 attempts to manage the secondary stack at the object creation site.

2928 operation to which the class-wide expression applies is a protected op.
2929 with a primitive_wrapper, verify that the updated inherited expression
2930 does not contain an internal call to a protected function. This
2931 completes the implementation of AI12-0166.

2944 (Is_Implicit_With_Clause): New routine.
2945 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2946 confusion with the with clause attribute by the same name.

2958 which marks implicit with clauses as related to an instantiation.
2959 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2960 (Parent_With): New routine.

2979 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2980 Secondary_Stack_Size handling as a pragma is now generated for the
2981 corresponding aspect instead of an attribute. Pragma expression is
2982 relocated instead of evaluated. Discriminant of the corresponding
2983 record type is referenced rather than the type discriminant.
2984 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2985 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2986 * sem_ch13.adb (Analyze_One_Aspect): Transform
2987 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2988 because the attribute does not have visibility on a task type's

3008 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3009 analysis on a copy of the expression with a copy of the index variable,
3010 because full expansion will rewrite construct into a loop with the
3011 original loop variable.
3012 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3013 expression is an iterated component association. Full analysis takes
