434 Refine the handling of freezing types for expression functions
435 that are not completions, when analyzing the generated body for
436 the function: the body is inserted at the end of the enclosing

438 the same scope that have not been frozen yet.
440 2018-08-21 Ed Schonberg <schonberg@adacore.com>
442 * sem_ch6.adb: Remove Freeze_Expr_Types.

464 2018-08-21 Ed Schonberg <schonberg@adacore.com>
466 * sem_ch6.adb (Check_Synchronized_Overriding): The conformance
467 between an overriding protected operation and the overridden
468 abstract progenitor operation requires subtype conformance;
469 requiring equality of return types in the case of a function is
470 too restrictive and leads to spurious errors when the return
471 type is a generic actual.

499 (Check_Declaration): Consider both deep (including elementary
500 access) object declarations and normal variables. First check

527 Perm_Error if there is any mismatch.
528 (Return_Declarations, Return_Globals, Return_The_Global): Check
529 the state of a given name at the end of the subprogram. These
530 procedures may change depending on how we shall finally deal
531 with globals and the rhs state in a move operation.
532 (Set_Perm_Extensions, Set_Perm_Prefixes_Borrow,
533 Set_Perm_Prefixes, Setup_Globals, Setup_Parameter_Or_Global,

1041 we continued freezeing entities outside of the subprogram. Now, when
1042 climbing the parents chain to locate the correct placement for the
1043 freezeing node, we check if the entity can be frozen and only when no
1044 enclosing node is marked as Must_Not_Freeze the entity is frozen.

1056 Its code is basically the previous version of this routine but extended
1057 with an additional parameter which is used to specify if during
1058 preanalysis we are allowed to freeze entities. If the new parameter is
1059 True then the subtree root node is marked as Must_Not_Freeze and no
1060 entities are frozen during preanalysis.
1061 (Preanalyze_And_Resolve): Invokes the internal version of
1062 Preanalyze_And_Resolve without entity freezing.
1063 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of

2114 * sem_ch3.adb (Access_Subprogram_Declaration): The flag
2115 Needs_Activation_Record is only needed on a subprogram type, not on a

2125 comment about the memset case.
2127 2018-05-30 Bob Duff <duff@adacore.com>
2129 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
2130 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
2131 We need to analyze it as part of analyzing the block, so that if the
2132 call to Element that initializes Elmt_Decl returns on the secondary
2133 stack, the block will ss_mark/ss_release. This block is inside the
2134 loop; we don't want to leak memory until the loop exits. The purpose
2135 of analyzing Elmt_Decl first was to catch the error of modifying it,
2136 which is illegal because it's a loop parameter. The above causes us to
2137 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
2138 it on the Element entity, so we end up with an E_Variable node with the
2140 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
2141 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
2142 parameter not allowed" error if Is_Loop_Parameter.
2143 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
2144 trigger the call to Diagnose_Non_Variable_Lhs.

2149 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
2150 range values for System.Priority in CodePeer mode since the actual
2151 target compiler may provide a wider range.

2160 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
2161 a package body that is a compilation unit may contain blocks that
2162 declare local subprograms. In Subprogram_Unnesting Mode such
2163 subprograms must be handled as nested inside the (implicit) elaboration
2164 procedure that executes that statement part. To handle properly uplevel
2165 references we construct that subprogram explicitly, to contain blocks
2166 and inner subprograms, The statement part of the compilation unit
2167 becomes a call to this subprogram. This is only done if blocks are
2168 present in the statement list of the body.

2180 for subprogram instantiations to enter callable entity into Subp table.

2237 (Collect_Primitive_Operations): Handle untagged private types completed
2238 with a derivation of an untagged private type whose full view is a
2239 tagged type. In such case, collecting the list of primitives we may
2240 find two equality primitives: one associated with the untagged private

2503 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
2504 value when converting a float value to a fixed-point value. This is
2505 required for CCG because it handles fixed-point types by means of
2506 unsigned integer type variables. The range check is now performed using

2545 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
2546 when bounds of fixed type are static, to remove some spuerfluous
2547 implicit conversions and provide an accurate result when converting
2548 back and forth between the fixed point type and a floating point type.

2559 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
2560 constant with private view so we take the address of that entity.
2561 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
2562 any; all callers changed. Handle N_Indexed_Component like
2563 N_Attribute_Reference. Add N_Type_Conversion case.
2564 (Visit_Node): Indexed references can be uplevel if the type isn't
2566 (Unnest_Subprograms): Don't rewrite if no reference given. If call has

2571 * exp_aggr.adb (Flatten): Copy tree of expression in a component
2572 association with a range or a set of discrete choices, rather than

2629 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
2630 the declarations of single concurrent types because they fall in the
2631 category of full type and object declarations.

2661 (List_Entities): Do not output the linker section for record types,
2662 array types and variables.
2663 (Print_Expr): Factor out common processing for unary operators and
2664 special values. Adjust and reorder the various cases.
2665 (List_Object_Info): End with the linker section, if any.
2666 (List_Record_Info): Likewise.

2681 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2683 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
2684 of a fixed point type and the parent is a multiplying operation,
2685 resolve the operand with its own type because the context will impose a
2686 resulting type on the result of the multiplication by means of
2687 approriate conversion.
2689 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2691 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
2692 the in-place initialization aggregate created for pragmas
2693 Initialize_Scalars or Normalize_Scalars is performed with checks
2696 2018-05-25 Arnaud Charlet <charlet@adacore.com>

2720 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2722 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2723 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2724 into three distring cases rather than in one loop which attempts to
2725 handle all three cases. This rewrite eliminates an issue where the last
2726 frame of the stack cannot be freed, thus causing the memory range of a
2727 new frame to approach the overflow point of the memory index type.
2728 Since the overflow is logically treated as a
2729 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2730 (SS_Allocate_Static): New routine. The routine factorizes the static
2731 secondary stack-related code from the former SS_Allocate.
2733 2018-05-25 Sergey Rybin <rybin@adacore.com>

2740 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
2741 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2742 is created when the proper body of the stub is analyzed.
2743 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2744 is the proper body of a subunit, the cloned body must be inserted in
2745 the declarative list that contains the stub.
2747 2018-05-25 Justin Squirek <squirek@adacore.com>
2749 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
2750 generate code for 6.5(8-10) so that we don't get an assertion error
2751 when dealing with an incomplete return type.
2753 2018-05-25 Arnaud Charlet <charlet@adacore.com>

2782 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2784 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2785 Validate_Derived_Type_Instance, to verify that all interfaces
2786 implemented by the formal type are also implemented by the actual. The
2787 verification is complicated when an interface of the formal is declared
2788 in a generic unit and the actual is declared in an instance of it.
2789 There is currently no mechanism to relate an interface declared within
2790 a generic to the corresponding interface in an instance, so we must
2791 traverse the list of interfaces of the actual, looking for a name
2792 match, and verifying that that interface is declared in an instance.
2794 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
2796 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
2797 assertions; replace function versions of Next_Formal/Next_Actual with

2863 in loops at the library level.
2865 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2867 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
2868 declaration is inserted into the tree and analyzed at that point, so
2869 should not be reinserted when the body is constructed. Inside a
2870 generic, ensure that the body is not inserted twice in the tree.

4028 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
4029 delegate the secondary stack management when there is no suitable
4030 transient context, and the transient scope was intended to manage the

4170 either as an aspect specification or an explicit attribute
4171 specification clause, for the initialized object.

4246 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
4247 management of the secondary stack to an enclosing scope if there is no
4248 suitable construct to wrap, and the transient scope was intended to
4249 manage the secondary stack.
4250 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
4251 is a valid boundary for a transient expression which comes from the
4252 statements of the alternative, otherwise alternatives cannot be
4253 wrapped. Assignments of controlled objects which have controlled
4254 actions suppressed now stop the traversal as there is no point in
4255 looking for an enclosing construct. Add several N_xxx_Body choices to
4256 the termination conditions for completeness.

4258 and the associated comment on usage.

4263 (Resolve_Actuals): Account for additional cases where finalization
4264 actions are required by utilizing predicate Needs_Finalization rather
4266 (Resolve_Call): Type initialization procedures can now utilize
4267 transient scopes to manage the secondary stack, thus preventing leaks
4268 during initialization. Remove the previous kludgy algorithm which
4269 attempts to manage the secondary stack at the object creation site.

4317 in the generic unless they reference a formal subprogram. Clarify

4398 primitive_wrappers that correspond to explicit operations that override
4399 an interface primitive.
4400 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
4401 operation to which the class-wide expression applies is a protected op.
4402 with a primitive_wrapper, verify that the updated inherited expression
4403 does not contain an internal call to a protected function. This
4404 completes the implementation of AI12-0166.

4416 either implicitly or explicitly withed.
4417 (Is_Implicit_With_Clause): New routine.
4418 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
4419 confusion with the with clause attribute by the same name.

4431 which marks implicit with clauses as related to an instantiation.
4432 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
4433 (Parent_With): New routine.
4434 (Set_Implicit_With_From_Instantiation): Removed.

4452 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
4453 Secondary_Stack_Size handling as a pragma is now generated for the
4454 corresponding aspect instead of an attribute. Pragma expression is
4455 relocated instead of evaluated. Discriminant of the corresponding
4456 record type is referenced rather than the type discriminant.
4457 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
4458 Secondary_Stack_Size rep item checks to only look for the pragma rep.
4459 * sem_ch13.adb (Analyze_One_Aspect): Transform
4460 Aspect_Secondary_Stack_Size into a pragma instead of an attribute

4481 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
4482 analysis on a copy of the expression with a copy of the index variable,
4483 because full expansion will rewrite construct into a loop with the
4484 original loop variable.
4485 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
4486 expression is an iterated component association. Full analysis takes
4487 place when construct is rewritten as a loop.
4488 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
4489 is not safe for in-place assignment.
4490 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
