* sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
that has been constant-folded, preserve information of original tree,
for ASIS uses.
(Analyze_Formal_Derived_Type): Set the limited present flag of the newly
generated private extension declaration if the formal derived type is
synchronized. Carry synchronized present over to the generated private
extension.
(Validate_Derived_Type_Instance): Ensure that the actual of a
synchronized formal derived type is a synchronized tagged type.
(Instantiate_Formal_Package): When creating the instantiation used to
validate the actual package of a formal declared without a box, check
whether the formal itself depends on a prior actual.
(Instantiate_Formal_Subprogram): Create new entities for the defining
identifiers of the formals in the renaming declaration, for ASIS use.
(Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
a renaming declaration or a subtype declaration for an actual in an
instance, capture location information of declaration in generic, for
ASIS use.
(Instantiate_Formal_Package): Add comments on needed additional tests.
AI-317 (partial parametrization) is fully implemented.
(Validate_Private_Type_Instance): Add check for actual which
must have preelaborable initialization
Use new // insertion for some continuation messages
(Analyze_Formal_Object_Declaration): Change usage of Expression to
Default_Expression. Add type retrieval when the declaration has an
access definition. Update premature usage of incomplete type check.
(Check_Access_Definition): New subsidiary routine. Check whether the
current compilation version is Ada 05 and the supplied node has an
access definition.
(Instantiate object): Alphabetize local variables. Handle the creation
of new renaming declarations with respect to the kind of definition
used - either an access definition or a subtype mark. Guard against
unnecessary error message in the context of anonymous access types after
they have been resolved. Add check for required null exclusion in a
formal object declaration.
(Switch_View): A private subtype of a non-private type needs to be
switched (the base type can have been switched without its private
dependents because of the last branch of Check_Private_View.
(Check_Private_View): Do not recompute Base_Type (T), instead use cached
value from BT.
(Instantiate_Type): Emit an error message whenever a class-wide type of
a tagged incomplete type is used as a generic actual.
(Find_Actual_Type): Extend routine to handle a component type in a child
unit that is imported from a formal package in a parent.
(Validate_Derived_Type_Instance): Check that analyzed formal and actual
agree on constrainedness, rather than checking against ultimate ancestor
(Instantiate_Subprogram_Body): Create a cross-reference link to the
generic body, for navigation purposes.
