Method Details

setStackPointerDelta
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
- Returns:
- an integer or null if none
-
setCallsitePrototype
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
- 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.
