public interface Specializeable

This instruction will be smart enough to potentially provide a specialized version of itself. Specialized instructions must still conform to the same semantics of an ordinary instruction, but it can elect to provide a more efficient implementation of itself.

Method Summary

Modifier and Type	Method and Description
CallBase	specializeForInterpretation() Interpreter can ask the instruction if it knows how to make a more efficient instruction for direct interpretation.

Method Detail

specializeForInterpretation

CallBase specializeForInterpretation()

Interpreter can ask the instruction if it knows how to make a more efficient instruction for direct interpretation.

Returns:

itself or more efficient but semantically equivalent instr
