Turns on factorization step 3.
#pragma factor3
Compiler performs the factorization step 3. To turn off factor3, use nofactor3. This optimization is performed on local variables after register allocation. (SP-offset) addressing is transformed in register indirect addressing. This optimization is performed after register allocation because only at this point are the local variables accessed by stack location.
This pragma does not correspond to any panel setting in the Language panel. By default, this pragma is enabled at global optimization level 2 and above.
