Class AbstractAssembler

java.lang.Object

org.jikesrvm.compilers.common.assembler.AbstractAssembler

Direct Known Subclasses:

Assembler

public abstract class AbstractAssembler
extends Object

This class has been created to work around a bug whereby the system seems to have gotten confused by the relationship between:

ForwardReference -> ForwardReference.ShortBranch -> Assembler.ShortBranch, and Assembler

This problem does not exist under IA32 since there is no need for Assembler.ShortBranch.
