* sem_res.ads, sem_res.adb (Process_Allocator): Do not propagate the
chain of coextensions when an allocator serves as the root of such a
chain.
(Propagate_Coextensions): Remove the test for the root being an
allocator.
(Resolve_Allocator): Add condition to ensure that all future decoration
occurs on an allocator node. Add processing and cleanup for static
coextensions.
(Valid_Conversion): If the operand type is the limited view of a
class-wide type, use the non-limited view is available to determine
legality of operation.
(Ambiguous_Character): move to spec, for use elsewhere.
(Ambiguous_Character): Handle Wide_Wide_Character in Ada 2005 mode
(Resolve_Range): Diagnose properly an ambiguous range whose bounds are
character literals.
(Resolve_Arithmetic_Op): Call Activate_Division_Check instead of setting
Do_Division_Check flag explicitly.
(Resolve_Actuals): If the actual is of a synchronized type, and the
formal is of the corresponding record type, this is a call to a
primitive operation of the type, that is declared outside of the type;
the actual must be unchecked-converted to the type of the actual
(Resolve_Call): Kill all current values for any subprogram call if
flag Suppress_Value_Tracking_On_Call is set.
(Resolve_Type_Conversion): Generate error message the the operand
or target of interface conversions come from a limited view.
(Check_Infinite_Recursion): Ignore generated calls
(Check_Allocator_Discrim_Accessibility): New procedure for checking
that an expression that constrains an access discriminant in an
allocator does not denote an object with a deeper level than the
allocator's access type.
(Resolve_Allocator): In the case of an allocator initialized by an
aggregate of a discriminated type, check that associations for any
access discriminants satisfy accessibility requirements by calling
Check_Allocator_Discrim_Accessibility.
(Resolve_Equality_Op): Handle comparisons of anonymous access to
subprogram types in the same fashion as other anonymous access types.
(Resolve_Concatenation_Arg): Remove initial character '\' in an error
message that is not a continuation message.
(Resolve_Type_Conversion): Add missing support for conversion to
interface type.
(Resolve_Actuals): Introduce a transient scope around the call if an
actual is a call to a function returning a limited type, because the
resulting value must be finalized after the call.
(Resolve_Actuals): If the call was given in prefix notations, check
whether an implicit 'Access reference or implicit dereference must be
added to make the actual conform to the controlling formal.
