* exp_ch7.ads, exp_ch7.adb (Expand_Cleanup_Actions): Set Sloc of
inserted cleanup code appropriately for GDB use.
(Make_Deep_Proc): Use Make_Handler_For_Ctrl_Operation to create
exception handler for Deep_Adjust or Deep_Finalize.
(Make_Handler_For_Ctrl_Operation): New subprogram. When runtime entity
Raise_From_Controlled_Operation is available, use a call to that
subprogram instead of a plain "raise Program_Error" node to raise
Program_Error if an exception is propagated from an Adjust or Finalize
operation.
(Insert_Actions_In_Scope_Around): If the statement to be wrapped
appears in the optional statement list of a triggering alternative, the
scope actions can be inserted directly there, and not in the list that
includes the asynchronous select itself.

* exp_ch6.ads, exp_ch6.adb (Expand_Call): When adding an extra
accessibility actual, check for the case of an aliased object that has
been rewritten as an Access attribute, and assign Prev to Prev_Orig so
we fall into processing for the attribute rather than the name of the
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
return value as Controlled.
(Is_In_Place_Function): If the return type is a limited interface,
treat as returning in place. The actual returned object may not always
be limited, but the caller has to assume that it is returned in place.
(Add_Final_List_Actual_To_Build_In_Place_Call): If the call is the
context of an allocator, use the correct finalization chain (that is,
the chain belonging to the access type, rather than the chain belonging
to the current scope).
(Add_Alloc_Form_Actual_To_Build_In_Place_Call): Test for a tagged
result type rather than a controlling result as a precondition for
adding an allocation form actual to a build-in-place call.
(Add_Final_List_Actual_To_Build_In_Place_Call): Ditto.
(Freeze_Subprogram): Code cleanup. Remove all the code that register the
primitive in the dispatch tables. This work is now done by Make_DT when
the type is frozen.
(Register_Predefined_DT_Entry): Removed.
(Add_Return): If end label is not present, use sloc of last statement
for generated return statement in procedure, for better gdb behavior
on expanded code.
(Add_Access_Actual_To_Build_In_Place_Call): Set parent fields of the
object address nodes to ensure proper processing by routines like
Insert_After*.
(Expand_Call): Fix generation of validity check for parameter
(Add_Alloc_Form_Actual_To_Build_In_Place_Call): Return without passing
the allocation form parameter if the result subtype is constrained,
except when the function has a controlling result.
(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
controlling result, since that also requires passing a finalization
list.
(Make_Build_In_Place_Call_In_Allocator): Call Add_Alloc_Form_Actual_*
even when the result subtype is constrained, to handle calls involving
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
calls involving controlling results.
(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
now performs the test).
(Make_Build_In_Place_Call_In_Object_Declaration):
Add_Alloc_Form_Actual_* is now called even when the result subtype is
constrained, to handle calls involving controlling results.
(Add_Return): Accomodate rewritten pattern from local raise to goto
transformation, so that we still recognize an transfer statement
and do the right thing here in that case.
(Expand_N_Subprogram_Body): Add dummy Push/Pop_xxx_Label nodes at start
and end of subprogram code.
(Register_Interface_DT_Entry, Register_Predefined_DT_Entry): Add missing
support for primitives that are functions (without formals) with a
controlling result.
(Inherited_From_Formal): If the actual subtype has not generic parent
type, it is not an actual for a formal derived type, and there is no
operation to inherit from the formal.

* exp_ch5.adb (Expand_N_Assignment_Statement): For the assignment of a
controlled type, use Make_Handler_For_Ctrl_Operation to construct the
required exception handler.
(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
return is installed, to ensure that finalizable components
of the expression use the proper finalization list. Guard the call to
Move_Final_List with a check that there is something to finalize.
(Make_Tag_Ctrl_Assignment): Use "old" handling
of controlled type assignment for virtual machines, since new code uses
unsupported features (such as direct access to bytes in memory).

(Inside_A_Return_Statement): New function inside Complete_Coextension_
Finalization.
(Expand_Record_Equality): Skip components that are interface types.
(Displace_Allocator_Pointer): Add missing support for interface subtypes
(Expand_N_Allocator): Replace invocation of Is_Local_Access_Discriminant
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
function result type, and use the finalization list associated with the
function scope in that case (such an anonymous type should not be
treated like an access parameter's type).

wrapper when the full view of the controlling type of an inherited
function that dispatches on result implements interfaces.
(Expand_N_Object_Declaration): In cases where the type of the
declaration is anonymous access, create finalization list for it.
(Expand_N_Object_Declaration): Generate a persistent_bss directive only
if the object has no explicit initialization, to match description of
functionality of pragam Persistent_BSS.
(Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
new function to build static aggregates, to replace initialization call
when static initialization is desired.
(Freeze_Type): Generate a list controller for an access type whenever
its designated type has controlled anonymous access discriminants.
(Build_Equivalent_Aggregate): New procedure to compute a static
aggregate to be used as default initialization for composite types,
instead of a generating a call to the initialization procedure for the
type.
(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
components, create a Master_Entity for it only if it contains tasks.
(Build_Init_Procedure): Suppress the tag assignment compiling under
no run-time mode.
(Freeze_Record_Type): Remove code associated with creation of dispatch
table.
(Init_Secondary_Tags): Update type of actuals when generating calls to
Ada.Tags.Set_Offset_To_Top
(Stream_Operation_OK): Disable use of streams compiling under no
run-time mode
(Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
if Has_Init_Expression set.
(Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
Register_Primitive, which provides the same functionality.
(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
function Is_Predefined_Dispatching_Operation.
(Make_Eq_If): When generating the list of comparisons for the
components of a given variant, omit the controller component that is
present if the variant has controlled components.

checks on access attributes, since this case is now captured by
Is_Local_Anonymous_Access.
(Analyze_Access_Attribute): Set Address_Taken on entity
(Analyze_Attribute, case Address): Set Address_Taken on entity
(OK_Self_Reference): Traverse tree to locate enclosing aggregate when

(Resolve_Attribute): In case of attributes 'Code_Address and 'Address
applied to dispatching operations, if freezing is required then we set
the attribute Has_Delayed_Freeze in the prefix's entity.
(Check_Local_Access): Set flag Suppress_Value_Tracking_On_Call in
current scope if access of local subprogram taken
(Analyze_Access_Attribute): Check legality of self-reference even if the
expression comes from source, as when a single component association in
an aggregate has a box association.
(Resolve_Attribute, case 'Access): Do not apply accessibility checks to
the prefix if it is a protected operation and the attribute is
Unrestricted_Access.
(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
node is rewritten as an interface conversion. leave unanalyzed after
resolution, to ensure that type checking against the context will take

_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

(Packed_Array_Aggregate_Handled): If the component type is itself a

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

components are compile-time known constants.
(Expand_Record_Aggregate): Force conversion of aggregates of tagged

(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

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

(Try_Primitive_Operation): When examining all primitive operations of a
tagged type, do not consider subprograms labeled as hidden unless they
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
interpreted as an indexing.
(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
prefix if the prefix has a synchronized type and the type of the formal
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
a limited_with_clause, the selected component is not part of a prefixed
call.
(Complete_Object_Operation): Diagnose properly an object that is not
aliased when the corresponding controlling formal is an access
parameter.
(Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
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
operations are attached to the corresponding record.
(Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
When processing a primitive of a concurrent type which implements an
interface change the type of all controlling formals to that of 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
Check_Convention) in a new local function Skip_Check.
(Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
confusion with Check_Conventions' own Prim_Op local variable.
(Create_Extra_Formals): Test for a tagged result type rather than a
controlling result when determining whether to add a BIP_Alloc_Form
formal and a BIP_Final_List formal to the function.
(Check_Conformance); For parameters that are anonymous access types,
subtype conformance requires that the not null and the constant
indicators must match
(Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
to retrieve the appropriate type when processing a concurrent type
declared within a generic. Minor comment reformatting. Change invocation
of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
mitive.
(Analyze_Subprogram_Body): If the return type of a function is an
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
raise statements to gotos, to retain proper warnings in this case.
(Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
nodes when looking for last statement.
