- requeue statement is dispatching. Do not emit an error when the name is
- not an entry and the context is a dispatching select. Add code to
- perform subtype conformance between the formals of the current entry
- and those of the target interface primitive.
- (Analyze_Asynchronous_Select, Analyze_Conditional_Entry_Call, Analyze_
- Timed_Entry_Call): Analyze the triggering statement as the first step of
- the processing. If this is a dispatching select, postpone the analysis
- of all select statements until the Expander transforms the select. This
- approach avoids generating duplicate identifiers after the Expander has
- replicated some of the select statements. In case the Expander is
- disabled, perform regular analysis.
- (Check_Triggering_Statement): New routine.
- (Analyze_Requeue): Exclude any interpretations that are not entries when
- checking overloaded names in a requeue. Also test type conformance for
- matching interpretations rather than requiring subtype conformance at
- that point to conform with the RM's resolution rule for requeues.

- * exp_util.ads, exp_util.adb:

- be null, so we get better tracking.
- (Ensure_Defined): create an itype reference only in the scope of the
- itype.
- (Side_Effect_Free): A selected component of an access type that
- denotes a component with a rep clause must be treated as not
- side-effect free, because if it is part of a linked structure its
- value may be affected by a renaming.
- (Expand_Subtype_From_Expr): For limited objects initialized with build
- in place function calls, do nothing; otherwise we prematurely introduce
- an N_Reference node in the expression initializing the object, which

- belong to a private generic type with a tagged parent.
- (Try_Object_Operation): Extensive rewriting, to handle properly various
- overloading cases, when several ancestors may have class-wide operations
- that are possible candidates, and when the overloaded functions return
- array types and have defaulted parameters so that the call may be

- (Analyze_Allocator): Remove Mark_Allocator and its invocation.
- (Process_Function_Call): use Next, rather than Next_Actual, to analyze
- successive actuals before analyzing the call itself.
- (Try_Primitive_Operation): A primitive operation is compatible with the

- is its corresponding record, as can be the case when the primitive
- operation is declared outside of the body of the type.
- (Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
- perform homonym traversal, looking for class-wide operation matches
- (formerly done in statements of Try_Class_Wide_Operation). Matches on
- access parameters are now restricted to anonymous access types.
- (Mark_Allocator): An allocator with a discriminant association parent is
- a coextension.
- (Try_One_Prefix_Interpretation): If the type of the object is
- incomplete, as can be happen when it is a limited view obtained through

- aliased when the corresponding controlling formal is an access
- parameter.

- ambiguous calls in prefixed notation, where two primitives differ only
- in that the controlling argument of one is an access parameter.
-
- * sem_ch6.adb (Has_Single_Return): Add guard in code that determines
- whether a function that returns an unconstrained type can be inlined.
- (Process_Formals): Diagnose properly the illegal use of an incomplete
- type in the profile of an access_to_subprogram declaration.
- (Check_Synchronized_Overriding): Nothing check for concurrent types, the

- corresponding record type.
- (Check_Synchronized_Overriding): Relax the conditional logic when trying
- to determine the tagged type to which a primitive belongs.
- (Check_Conventions): Capture condition to ignore a primitive operation
- (which is shared between the loop in Check_Conventions and the one in

- controlling result when determining whether to add a BIP_Alloc_Form
- formal and a BIP_Final_List formal to the function.

- anonymous access to the limited view of a class-wide type, and the
- non-limited view of the type is available, update the type of the
- function so that code can be generated.
- (Process_Formals): In case of access-subtype itype whose designated
- type is also an itype (situation that happens now with access to
- subprograms) we mark the access-type itype with the Has_Delayed_Freeze
- attribute to avoid backend problems.
- (Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
- init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
- anonymous types' designated types are same before testing
- Subtypes_Statically_Match.
- (Create_Extra_Formals): Test for a named access parameter that is a
- controlling formal as an additional condition for adding an
- accessibility level formal. This can occur in the subp type created for
- dispatching calls in Expand_Dispatching_Call, and allows calling
- Create_Extra_Formals from that procedure rather than special-casing the
- extra formals there.
- (Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
- when the function has a controlling result.
- (Check_Returns): Add much more knowledge of the optimization of local

- (Gen_Ctrl_Actions_For_Aggr): In call to Init_Controller, pass False to

- (Gen_Ctrl_Actions_For_Aggr): When processing an aggregate of a

- already existing one.
- (Static_Array_Aggregate): New procedure to construct a positional
- aggregate that can be handled by the backend, when all bounds and
- components are compile-time known constants.
- (Expand_Record_Aggregate): Force conversion of aggregates of tagged
- types covering interface types into assignments.
- (Replace_Type): move to Build_Record_Aggr_Code.
- (Expand_Record_Aggr_Code): if the target of the aggregate is an
- interface type, convert to the definite type of the aggregate itself,
- so that needed components are visible.
- (Convert_Aggr_In_Object_Decl): If the aggregate has controlled
- components and the context is an extended return statement do not
- create a transient block for it, to prevent premature finalization
- before the return is executed.
- (Gen_Assign): Do not generate a call to deep adjust routine if the
- component type is itself an array of controlled (sub)-components
- initialized with an inner aggregate.
- (Component_Check): New name for Static_Check. This name is now more
- appropriate, and documentation is added which was missing.
- (Component_Check): Add test for bit aligned component value
- (Component_Not_OK_For_Backend): Renames Has_Delayed_Nested_Aggregate_Or_

- _disp_get_task_id.
- Disable new Ada 05 accessibility check for JVM.NET targets, which
- cannot be implemented in a practical way.
- (Expand_N_Attribute_Reference: case Attribute_Tag): The use of 'Tag in
- the sources always references the tag of the actual object. Therefore,
- if 'Tag is applied in the sources to class-wide interface objects we
- generate code that displaces "this" to reference the base of the object.
- (Expand_N_Attribute_Reference, case Size): Return specified size if
- known to front end.
- (Expand_N_Attribute_Reference): The expansion of the 'Address attribute
- has code that displaces the pointer of the object to manage interface
- types. However this code must not be executed when the prefix is a
- subprogram. This bug caused the wrong expansion of the internally
- generated assignment that fills the dispatch table when the primitive

- (Resolve_Attribute, case 'Access): Set the Etype of the attribute
- reference to the base type of the context, to force a constraint check
- when the context is an access subtype with an explicit constraint.
- (Analyze_Attribute, case 'Class): If the prefix is an interface and the

- (Build_Initialization_Call): When available, replace a call to the
- initialization procedure with a copy of the equivalent static aggregate
- for the type.
- (Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
- declarations for objects of a class-wide interface type, rather than
- just identifiers, to prevent visibility problems.
- (Expand_N_Object_Declaration): When expanding the declaration for an
- object of a class-wide interface type, preserve the homonym chain of
- the original entity before exchanging it with that of the generated
- renaming declaration.
- (Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
- active, because there is no way to handle the exception.
- (Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
- to do a minimum decoration of the Access_Disp_Table list.
- (Expand_Record_Controller): Avoid the addition of the controller between
- the component containing the tag of a secondary dispatch table and its
- adjacent component that stores the offset to the base of the object.
- This latter component is only generated when the parent type has
- discriminants ---documented in Add_Interface_Tag_Components).
- (Apply_Array_Size_Check): Removed, no longer needed.
- (Expand_N_Full_Type_Declaration): If the type has anonymous access

- (Requires_Init_Proc): Return false in case of interface types.
- (Add_Secondary_Tables): Use the new attribute Related_Interface to
- cleanup the code.
- (Predefined_Primitive_Freeze): Do not assume that an internal entity
- is always associated with a predefined primitive because the internal
- entities associated with interface types are not predefined primitives.
- Therefore, the call to Is_Internal is replaced by a call to the

- Finalization.
- (Expand_Record_Equality): Skip components that are interface types.
- (Displace_Allocator_Pointer): Add missing support for interface subtypes

- with Rewrite_Coextension. Change the condition for detecting coextension
- root nodes.
- (Is_Local_Access_Discriminant): Removed.
- (Rewrite_Coextension): New routine which rewrites a static coextension
- as a temporary and uses its unrestricted access in the construction of
- the outer object.
- (Complete_Coextension_Finalization): New routine. Generate finalization
- attachment calls to all delayed coextensions.
- (Expand_N_Allocator): Call Complete_Coextension_Finalization whenever
- the allocator is not a coextension itself and has delayed coextensions.
- If the current allocator is controlled, but also a coextension, delay
- the generation of the finalization attachment call.
- Rename local variable "Node" to "Nod" in order to avoid confusion with
- "Elists.Node".
- (Expand_Allocator_Expression): Call Adjust for initialized allocators of
- limited types that are not inherently limited. Such an allocator is
- illegal, but is generated by the expander for a return statement, to
- copy the result onto the secondary stack. This is the only case where a
- limited object can be copied. Generate code to displace the pointer
- to the object if the qualified expression is a class-wide interface
- object. Such displacement was missing and hence the copy of the object
- was wrong.
- (Apply_Accessibility_Check): Handle allocated objects initialized in
- place.
- (Displace_Allocator_Pointer): Subsidiary procedure to Expand_N_Allocator
- and Expand_Allocator_Expression. Allocating class-wide interface objects
- this routine displaces the pointer to the allocated object to reference
- the component referencing the corresponding secondary dispatch table.
- Expand_Allocator_Expression): Add missing support to allocate class-wide
- interface objects initialized with a qualified expression.
- (Get_Allocator_Final_List): Test for an anonymous access type that is a

- (Expand_Simple_Function_Return, Expand_N_Return_Statement): Handle
- properly the case of a function whose return type is a limited
- class-wide interface type. Modify the code of the accessibility
- check to handle class-wide interface objects. In this case we need to
- displace "this" to reference the primary dispatch table to get access
- to the TSD of the object (to evaluate its accessibility level).
- (Expand_N_Extended_Return_Statement): Test for a tagged result type
- rather than a controlling result as one of the conditions for
- generating tests of the implicit BIP_Alloc_Form formal. The
- initialization assignment is also handled according to whether the
- result is tagged instead of controlling.
- In the case where the init assignment is inserted in the "then" part of
- the allocation conditional, rewrite the target to be a dereference of
- the implicit BIP_Object_Access formal.
- If the returned value is unconstrained and created on the secondary
- stack, mark the enclosing block and function so that the secondary
- stack is not reclaimed on return.
- Treat returns from functions with controlling results similarly to
- returns from functions with unconstrained result subtypes.
- If the object returned is unconstrained, and an allocator must be
- created for it, analyze the allocator once the block for the extended

- of the expression use the proper finalization list. Guard the call to
- Move_Final_List with a check that there is something to finalize.

- object.
- (Expand_Inline_Call): If an actual is a literal, and the corresponding
- formal has its address taken in the body, create a temporary to capture
- value. If the return type is a limited interface, do not treat the

- (Is_In_Place_Function): If the return type is a limited interface,

- (Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged

- (Add_Final_List_Actual_To_Build_In_Place_Call): Test Controlled_Type
- rather than Is_Controlled and Has_Controlled_Component, since we want to
- include class-wide result types in this treatment. Also test for a

- list.
- (Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*

- controlling results.
- (Make_Build_In_Place_Call_In_Anonymous_Context): Add_Alloc_Form_Actual_*
- is now called even when the result subtype is constrained, to handle

- (Make_Build_In_Place_Call_In_Assignment): Remove test for Is_Constrained
- on call to Add_Alloc_Form_Actual_To_Build_In_Place_Call (that procedure

- The TSD has a discriminant containing the Inheritance Depth Level,
- value that is used in the membership test but also to fix the size
- of the table of ancestors.
- (Expand_Interface_Conversion): Insert function body at the closest place

- Thus we must convert the low bound and the length to an appropriate
- type before doing the sum.
- (Build_Subprogram_Receiving_Stubs, PolyORB):
- * Retrieve the extra formals parameters at the
- end of the parameter stream.
- * Use Move_Any_Value to write back out parameters

- (TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
- (FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
- typecode from the Etype. Therefore we retrieve the correct typecode
- with a call to Get_Any_Type.
- (Copy_Specification): Do controlling formal type substitution based on
- Is_Controlling_Formal flag, instead of caller-provided object type.
- (Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
- a RACW primitive operation, we might get a subprogram declaration for an
- ancestor of the RACW designated type (not for the designated type
- itself), in the case where this operation is inherited. In this case we
- have no easy means of determining the original tagged type for which
- the primitive was declared, so instead we now rely on
- Copy_Specification to use the Is_Controlling_Formal flag to determine
- which formals require type substitution.

- Fixes regression on 8515-003 with implementation of AI-133.

- * sem_ch4.adb (Try_Primitive_Operation): The call is legal if the

- Whether they can be allocated statically is determined in exp_ch4.
- (Analyze_Selected_Component): If the prefix is a limited view and the

- (Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
- therefore illegal), suggest a qualified expression rather than a type
- conversion, because a type conversion would be illegal in this context.
- (Anayze_Allocator): Trace recursively all nested allocators so that all
- coextensions are on the corresponding list for the root. Do no mark
- coextensions if the root allocator is within a declaration for a stack-
- allocated object, because the access discriminants will be allocated on
- the stack as well.
- (Analyze_Call): Remove restriction on calls to limited functions for the
- cases of generic actuals for formal objects, defaults for formal objects
- and defaults for record components.
- (Analyze_Allocator): Before analysis, chain coextensions on the proper
- element list. Their expansion is delayed until the enclosing allocator
- is processed and its finalization list constructed.
- (Try_Primitive_Operation): If the prefix is a concurrent type, looks
- for an operation with the given name among the primitive operations of
- the corresponding record type.
- (Analyze_Selected_Component): If the prefix is a task type that
- implements an interface, and there is no entry with the given name,
- check whether there is another primitive operation (e.g. a function)
- with that name.
- (Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
- properly the indexing of a function call written in prefix form, where
- the function returns an array type, and all parameters of the function
- except the first have defaults.
- (Analyze_Equality_Op): If this is a call to an implicit inequality, keep
- the original operands, rather than relocating them, for efficiency and
- to work properly when an operand is overloaded.
- (Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
- Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
- (Analyze_Selected_Component): If the prefix is a private extension, only
- scan the visible components, not those of the full view.
- (Try_Primitive_Operation): If the operation is a procedure, collect all
- possible interpretations, as for a function, because in the presence of
- classwide parameters several primitive operations of the type can match
- the given arguments.

- (New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into

-
- * sem_dist.adb (Add_RAS_Dereference_TSS):
- Change primitive name to _Call so it cannot clash with any legal

- Mark the full view of the designated type for the RACW associated with
- a RAS as Comes_From_Source to get proper view switching when installing
