Method Details

addPcodeOpTemplate

public void addPcodeOpTemplate(Object opT)
                        throws SledException

Throws:

SledException

trimToSize

public void trimToSize()

optimize

public void optimize()

The default pcode generated for a constructor is typically not very efficient. For example, for an add instruction, we might generate something like tmp1 = LOAD register_space register1 tmp2 = LOAD register_space register2 tmp3 = ADD tmp1 tmp2 STORE register_space register3 tmp3 This routine marks opcodes and varnodes as potentially omitable, which allows us to generate much simpler pcode whenever there are no dynamic references involved. In the case above we would replace the 4 pcode ops above with a single pcode op: register3 = ADD register1 register2

getFlowFlags

public int getFlowFlags()

getPcode

public Handle getPcode(ArrayList<PcodeOp> pcode,
 Position position,
 int off,
 ArrayList<PcodeOp> delayPcode)
                throws Exception

Method getPcode. Recursive pcode generation method.

Parameters:

pcode - - current list of pcode instructions to which we will append new instructions

position -

off -

delayPcode - - pcode for instruction(s) in delay slot

Returns:

HandleTemplate - handle for the result of this constructors pcode

Throws:

Exception

delaySlotDepth

public int delaySlotDepth()

result

public HandleTemplate result()
