* 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_*

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.

of controlled type assignment for virtual machines, since new code uses
unsupported features (such as direct access to bytes in memory).

copy the result onto the secondary stack. This is the only case where a

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.
