  • Method Details

    • setStackPointerDelta

      public void setStackPointerDelta(Integer spDelta)
      Set the stack-pointer delta after the execution of an instruction. Typically, this is used on branching instructions to dynamic callsites that have not been determined automatically.
      Parameters:
      spDelta - a delta; null to remove

    • getStackPointerDelta

      public Integer getStackPointerDelta()
      Returns:
      an integer or null if none

    • setCallsitePrototype

      public void setCallsitePrototype(IPrototypeItem callsiteProto)
      Set the prototype associated with a callsite target. Typically, this is used on branching instructions instructions to dynamic callsites that have not been determined automatically.
      Parameters:
      callsiteProto - a prototype; null to remmove

    • getCallsitePrototype

      public IPrototypeItem getCallsitePrototype()
      Returns:
      a prototype or null if none

    • isTailCall

      public boolean isTailCall()

    • setTailCall

      public void setTailCall(boolean isTailCall)

    • isCondTailCall

      public boolean isCondTailCall()

    • setCondTailCall

      public void setCondTailCall(boolean isCondTailCall)

    • getSwitchDispatcher

      public int getSwitchDispatcher()
      Get value indicating whether branching instruction may be a switch dispatcher (heuristic).
      Returns:
      0:no, 1: yes, not processed, 2: yes, processed

    • setSwitchDispatcher

      public void setSwitchDispatcher(int switchDispatcher)

    • isFakeCall

      public boolean isFakeCall()
      Returns:
      true if instruction is a routine call that should be considered as an intra-routine branch, false otherwise.

    • setFakeCall

      public void setFakeCall(boolean isFakeCall)

    • isActualCall

      public boolean isActualCall()

    • setActualCall

      public void setActualCall(boolean isActualCall)

    • isCustomBranchingInstruction

      public boolean isCustomBranchingInstruction()
