3 * exp_ch6.adb (Add_Unconstrained_Actuals_To_Build_In_Place_Call): Do
4 not add any actuals when the size of the object is known, and the
5 caller will allocate it.
6 (Build_Heap_Allocator): Rename to Build_Heap_Or_Pool_Allocator to

8 generated code. Generate a branch for the heap and pool cases where
9 the object is not necessarity controlled.

11 statement into four branches depending the requested mode if the caller
12 will not allocate the object on its side.
13 (Make_Build_In_Place_Call_In_Allocator): Do not allocate a controlled

543 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
544 We need to analyze it as part of analyzing the block, so that if the
545 call to Element that initializes Elmt_Decl returns on the secondary
546 stack, the block will ss_mark/ss_release. This block is inside the
547 loop; we don't want to leak memory until the loop exits. The purpose
548 of analyzing Elmt_Decl first was to catch the error of modifying it,
549 which is illegal because it's a loop parameter. The above causes us to
550 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
551 it on the Element entity, so we end up with an E_Variable node with the
553 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
554 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
555 parameter not allowed" error if Is_Loop_Parameter.
556 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
557 trigger the call to Diagnose_Non_Variable_Lhs.

561 * checks.adb (Apply_Scalar_Range_Check):
562 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
563 range values for System.Priority in CodePeer mode since the actual
564 target compiler may provide a wider range.

571 2018-05-30 Ed Schonberg <schonberg@adacore.com>
573 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
574 a package body that is a compilation unit may contain blocks that
575 declare local subprograms. In Subprogram_Unnesting Mode such
576 subprograms must be handled as nested inside the (implicit) elaboration
577 procedure that executes that statement part. To handle properly uplevel
578 references we construct that subprogram explicitly, to contain blocks
579 and inner subprograms, The statement part of the compilation unit
580 becomes a call to this subprogram. This is only done if blocks are
581 present in the statement list of the body.
583 2018-05-30 Bob Duff <duff@adacore.com>

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

917 value when converting a float value to a fixed-point value. This is
918 required for CCG because it handles fixed-point types by means of
919 unsigned integer type variables. The range check is now performed using

972 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
973 constant with private view so we take the address of that entity.
974 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
975 any; all callers changed. Handle N_Indexed_Component like
976 N_Attribute_Reference. Add N_Type_Conversion case.
977 (Visit_Node): Indexed references can be uplevel if the type isn't
979 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
980 been relocated, set first_named pointer in original node as well.

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

1074 (List_Entities): Do not output the linker section for record types,
1075 array types and variables.
1076 (Print_Expr): Factor out common processing for unary operators and
1077 special values. Adjust and reorder the various cases.
1078 (List_Object_Info): End with the linker section, if any.

1094 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1096 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1097 of a fixed point type and the parent is a multiplying operation,
1098 resolve the operand with its own type because the context will impose a
1099 resulting type on the result of the multiplication by means of
1100 approriate conversion.
1102 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1104 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of

1106 Initialize_Scalars or Normalize_Scalars is performed with checks

1133 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1135 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1136 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1137 into three distring cases rather than in one loop which attempts to
1138 handle all three cases. This rewrite eliminates an issue where the last
1139 frame of the stack cannot be freed, thus causing the memory range of a
1140 new frame to approach the overflow point of the memory index type.
1141 Since the overflow is logically treated as a
1142 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1143 (SS_Allocate_Static): New routine. The routine factorizes the static
1144 secondary stack-related code from the former SS_Allocate.

1154 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1155 is created when the proper body of the stub is analyzed.
1156 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1157 is the proper body of a subunit, the cloned body must be inserted in
1158 the declarative list that contains the stub.
1160 2018-05-25 Justin Squirek <squirek@adacore.com>
1162 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1163 generate code for 6.5(8-10) so that we don't get an assertion error

1197 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1198 Validate_Derived_Type_Instance, to verify that all interfaces
1199 implemented by the formal type are also implemented by the actual. The
1200 verification is complicated when an interface of the formal is declared
1201 in a generic unit and the actual is declared in an instance of it.
1202 There is currently no mechanism to relate an interface declared within
1203 a generic to the corresponding interface in an instance, so we must
1204 traverse the list of interfaces of the actual, looking for a name
1205 match, and verifying that that interface is declared in an instance.
1207 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1209 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra

1276 in loops at the library level.

1280 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1281 declaration is inserted into the tree and analyzed at that point, so
1282 should not be reinserted when the body is constructed. Inside a
1283 generic, ensure that the body is not inserted twice in the tree.

1775 iteration of an Ada2012 loop is performed to determine the type of the

2441 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2442 delegate the secondary stack management when there is no suitable
2443 transient context, and the transient scope was intended to manage the

2448 the comment on usage.
2449 (Find_Transient_Context): Change the initinte loop into a while loop.

2580 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
2581 properly object declarations with initializations that are
2582 build-in-place function calls, when there is an address specification,
2583 either as an aspect specification or an explicit attribute
2584 specification clause, for the initialized object.
2585 * freeze.adb (Check_Address_Clause): Do not remove side-effects from
2586 initial expressions in the case of a build-in-place call.
2588 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2590 * sem_eval.adb (Is_Null_Range): Retrieve the full view when called on a
2591 private (sub)type; refactor to avoid early return statement.

2600 * sem_util.adb (Is_Declaration): Reimplemented. The routine can now
2601 consider specific subsets of declarations.
2602 (Is_Declaration_Other_Than_Renaming): Removed. Its functionality is
2603 replicated by Is_Declaration.
2604 * sem_util.ads (Is_Declaration): New parameter profile. Update the

2627 2018-01-11 Justin Squirek <squirek@adacore.com>
2629 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
2630 to make sure a given expression function is properly parenthesized.

2641 scope of package Ada is Standard.
2643 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2645 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
2646 subcomponent of the current entity when building the body for a dynamic
2647 predicate function for a record with composite subcomponents.

2657 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
2658 Establish_Transient_Scope.
2659 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2660 management of the secondary stack to an enclosing scope if there is no
2661 suitable construct to wrap, and the transient scope was intended to
2662 manage the secondary stack.
2663 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2664 is a valid boundary for a transient expression which comes from the
2665 statements of the alternative, otherwise alternatives cannot be
2666 wrapped. Assignments of controlled objects which have controlled
2667 actions suppressed now stop the traversal as there is no point in
2668 looking for an enclosing construct. Add several N_xxx_Body choices to
2669 the termination conditions for completeness.
2670 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2671 and the associated comment on usage.
2672 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2673 Establish_Transient_Scope.

2676 (Resolve_Actuals): Account for additional cases where finalization
2677 actions are required by utilizing predicate Needs_Finalization rather
2679 (Resolve_Call): Type initialization procedures can now utilize
2680 transient scopes to manage the secondary stack, thus preventing leaks
2681 during initialization. Remove the previous kludgy algorithm which
2682 attempts to manage the secondary stack at the object creation site.
2684 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
2686 * libgnat/g-soliop__qnx.ads: New.

2725 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2727 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2728 formsl type corresponding to the actual fixed point type is private,
2729 because in this case there can be no suspicious arithmetic operations
2730 in the generic unless they reference a formal subprogram. Clarify
2733 2018-01-11 Javier Miranda <miranda@adacore.com>
2735 * exp_util.adb (Remove_Side_Effects): No action done for functions
2736 returning class-wide types since it requires generating code using
2737 'reference and the CCG target has no secondary stack.

2757 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2759 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2760 if it contains at least one component declaration employing a function
2761 call returning on the secondary stack.

2780 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2781 has a delayed aspect which must be processed at the point the type is

2798 Default_Sec_Stack_Size.
2799 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack

2807 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2809 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2810 legality of an inherited operation that may require overriding, ignore
2811 primitive_wrappers that correspond to explicit operations that override
2812 an interface primitive.
2813 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2814 operation to which the class-wide expression applies is a protected op.
2815 with a primitive_wrapper, verify that the updated inherited expression
2816 does not contain an internal call to a protected function. This
2817 completes the implementation of AI12-0166.
2819 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2821 * ali.adb: Document the remaining letters available for ALI lines.

2823 * ali.ads: Update type With_Record. Field
2824 Implicit_With_From_Instantiation is no longer in use. Add field
2826 * csinfo.adb (CSinfo): Remove the setup for attribute
2827 Implicit_With_From_Instantiation.
2828 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2829 either implicitly or explicitly withed.
2830 (Is_Implicit_With_Clause): New routine.
2831 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2832 confusion with the with clause attribute by the same name.

2838 (Implicit_With_On_Parent): Mark the with clause as generated for a
2840 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2841 instantiation are no longer marked as Implicit_With_From_Instantiation
2842 because they are already marked as implicit.
2843 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2844 which marks implicit with clauses as related to an instantiation.
2845 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2846 (Parent_With): New routine.
2847 (Set_Implicit_With_From_Instantiation): Removed.
2848 (Set_Parent_With): New routine.

2865 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2866 Secondary_Stack_Size handling as a pragma is now generated for the
2867 corresponding aspect instead of an attribute. Pragma expression is
2868 relocated instead of evaluated. Discriminant of the corresponding
2869 record type is referenced rather than the type discriminant.
2870 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2871 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2872 * sem_ch13.adb (Analyze_One_Aspect): Transform
2873 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2874 because the attribute does not have visibility on a task type's

2877 Attribute_Secondary_Stack_Size.
2878 * snames.adb-tmpl, snames.ads-tmpl: Remove

2894 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2895 analysis on a copy of the expression with a copy of the index variable,
2896 because full expansion will rewrite construct into a loop with the
2897 original loop variable.
2898 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2899 expression is an iterated component association. Full analysis takes
2900 place when construct is rewritten as a loop.
2901 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2902 is not safe for in-place assignment.
2903 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
