enterMULTIPLE_TIMES_IN_LOOP
protected int enterMULTIPLE_TIMES_IN_LOOP(int PC) Prepares the PC to get looped to.Thus it tries to assure a new basic block starts here. Additionally it reserves some space for the insertion of Phi-Functions.
Gets called when Label ExecutionOrder.MULTIPLE_TIMES_IN_LOOP got stepped over.
In most cases you don't want to invoke this function directly but to use
enter(ExecutionOrder.MULTIPLE_TIMES_IN_LOOP, int)
insteadSideeffects: currentSection is updated, instructions are inserted into the body
- Overrides:
enterMULTIPLE_TIMES_IN_LOOP
in classAbstractAndroidModel
- Parameters:
PC
- Program Counter instructions shall be placed at. In most cases you'll simply pass body.getNextProgramCounter()- Returns:
- Program Counter after insertion of the code
-
enterEND_OF_LOOP
protected int enterEND_OF_LOOP(int PC) Loops to MULTIPLE_TIMES_IN_LOOP.It inserts a gotoInstruction and fills the space reserved before with actual PhiInstructions
Gets called when Label ExecutionOrder.END_OF_LOOP got stepped over.
In most cases you don't want to invoke this function directly but to use
enter(ExecutionOrder.END_OF_LOOP, int)
insteadSideeffects: currentSection is updated, instructions are inserted into the body
- Overrides:
enterEND_OF_LOOP
in classAbstractAndroidModel
- Parameters:
PC
- Program Counter instructions shall be placed at. In most cases you'll simply pass body.getNextProgramCounter()- Returns:
- Program Counter after insertion of the code
