* sem_type.adb (Write_Overloads): Improve display of candidate
interpretations.
(Add_One_Interp): Do not add to the list of interpretations aliased
entities corresponding with an abstract interface type that is an
immediate ancestor of a tagged type; otherwise we have a dummy
conflict between this entity and the aliased entity.
(Disambiguate): The predefined equality on universal_access is not
usable if there is a user-defined equality with the proper signature,
declared in the same declarative part as the designated type.
(Find_Unique_Type): The universal_access equality operator defined under
AI-230 does not cover pool specific access types.

it matches the partial view of the other type.

(Analyze_Single_Protected, Analyze_Single_Task): Do not mark the object

object (for this purpose the object should be explicitly marked as
aliased, but being an anonymous type this is not possible).

redundant use clauses.
In particular, if the scope of two use clauses overlaps, but one is not
entirely included in the other, we should not warn. This can happen
with nested packages.
(Analyze_Subprogram_Renaming): Protect the compiler against previously

* sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
abstract interpretations on an operator, remove interpretations that
yield Address or a type derived from it, if one of the operands is an
integer literal.
(Try_Object_Operation.Try_Primitive_Operation,
Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
location when creating the new reference to a primitive or class-wide
operation as a part of rewriting a subprogram call.
(Try_Primitive_Operations): If context requires a function, collect all
interpretations after the first match, because there may be primitive
operations of the same type with the same profile and different return
types. From code reading.
(Try_Primitive_Operation): Use the node kind to choose the proper
operation when a function and a procedure have the same parameter
profile.
(Complete_Object_Operation): If formal is an access parameter and prefix
is an object, rewrite as an Access reference, to match signature of
primitive operation.
(Find_Equality_Type, Find_One_Interp): Handle properly equality given
by an expanded name with prefix Standard, when the operands are of an
anonymous access type.
(Remove_Abstract_Operations): If the operation is abstract because it is
inherited by a user-defined type derived from Address, remove it as
well from the set of candidate interpretations of an overloaded node.
(Analyze_Membership_Op): Membership test not applicable to cpp-class
types.
