Changing the number of registers

Hi, I am trying to change the number of registers for simplescalar's gcc (2.7.2.3) compiler. I modified the ss.h file - FIXED_REGISTERS bits and CALL_USED_REGISTERS bits, so as to leave just 8 integer and 4 FP registers. But when I do a live registers analysis, I get > 8 integer registers live.
