Class InterfaceMethodConflictResolver

java.lang.Object

org.jikesrvm.ia32.InterfaceMethodConflictResolver

public abstract class InterfaceMethodConflictResolver
extends Object

An interface conflict resolution stub uses a hidden parameter to distinguish among multiple interface methods of a class that map to the same slot in the class's IMT.

Assumption: Register EAX contains the "this" parameter of the method being called invoked.

Assumption: Register ECX is available as a scratch register (we need one!)
