Check that the --- body executed is determined by the type and tag of the operands. --- --- TEST DESCRIPTION: --- The formal tagged private type has an unknown discriminant part, and --- is thus indefinite. This allows both definite and indefinite types --- to be passed as actuals. For tagged types, definite implies --- nondiscriminated, and indefinite implies discriminated (with known --- or unknown discriminants). --- --- Only nonlimited tagged types are tested, since equality operators --- are not predefined for limited types. --- --- A tagged type is passed as an actual to a generic formal tagged --- private type. The tagged type overrides the predefined equality --- operator. A subprogram within the generic calls the equality operator --- of the formal type. In an instance, the equality operator denotes --- a view of the predefined operator of the actual type, but the --- call dispatches to the body of the overriding operator. --- --- --- CHANGE HISTORY: --- 06 Dec 94 SAIC ACVC 2.0 --- 21 Nov 95 SAIC ACVC 2.0.1 fixes: Corrected expected result on --- calls to "=" within the instance.
