    • replaceInstruction

      public static void replaceInstruction​(InstructionHandle ih, InstructionList replacementInstructions, LazyMethodGen enclosingMethod)
      replace an instruction handle with another instruction, in this case, a branch instruction.
      Parameters:
      ih - the instruction handle to replace.
      replacementInstructions - the branch instruction to replace ih with
      enclosingMethod - where to find ih's instruction list.

    • deleteInstruction

      public static void deleteInstruction​(InstructionHandle ih, LazyMethodGen enclosingMethod)
      delete an instruction handle and retarget all targeters of the deleted instruction to the next instruction. Obviously, this should not be used to delete a control transfer instruction unless you know what you're doing.
      Parameters:
      ih - the instruction handle to delete.
      enclosingMethod - where to find ih's instruction list.

    • deleteInstruction

      public static void deleteInstruction​(InstructionHandle ih, InstructionHandle retargetTo, LazyMethodGen enclosingMethod)
      delete an instruction handle and retarget all targeters of the deleted instruction to the provided target.
      Parameters:
      ih - the instruction handle to delete
      retargetTo - the instruction handle to retarget targeters of ih to.
      enclosingMethod - where to find ih's instruction list.

    • copyInstruction

      public static Instruction copyInstruction​(Instruction i)
      Fix for Bugzilla #39479, #40109 patch contributed by Andy Clement Need to manually copy Select instructions - if we rely on the the 'fresh' object created by copy(), the InstructionHandle array 'targets' inside the Select object will not have been deep copied, so modifying targets in fresh will modify the original Select - not what we want ! (It is a bug in BCEL to do with cloning Select objects). 
       declare error:
     call(* Instruction.copy()) && within(org.aspectj.weaver)
       && !withincode(* Utility.copyInstruction(Instruction)):
     "use Utility.copyInstruction to work-around bug in Select.copy()";
