Changing the number of registers

[murali]

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. Please tell me if there is something else I need to
take care of to change the number of registers.

  thanks,
  murali

problems - I read that, but it still didn't solve the problem
