org.jikesrvm.osr.ia32
Class CodeInstaller

java.lang.Object
  extended by org.jikesrvm.osr.ia32.CodeInstaller
All Implemented Interfaces:
Constants, HeapLayoutConstants, ArchConstants, BaselineConstants, RegisterConstants, StackframeLayoutConstants, TrapConstants, ThinLockConstants, TIBLayoutConstants, SizeConstants
Direct Known Subclasses:
ArchitectureSpecificOpt.CodeInstaller
public abstract class CodeInstaller
extends Object
implements BaselineConstants

CodeInstaller generates a glue code which recovers registers and from the stack frames and branch to the newly compiled method instructions. The glue code is installed right before returning to the threading method by PostThreadSwitch
