Hi, this might be a question not entirely valid w.r.t. new GCC versions 4.x+. I am using GCC 3.2.x
I have 2 questions regarding fixed_reg_set, call_used_reg_set, call_fixed_reg_set. Firstly, are fixed_reg_set, call_used_reg_set, call_fixed_reg_set always (or supposed to..) the same as fixed_reg, call_used_reg and call_fixed_reg, just as HARD_REG_SET representation? And secondly, is call_used_reg_set always a subset of fixed_reg_set, and call_fixed_reg_set always a subset of call_used_reg_set as well as subset of fixed_reg_set? Thanks for help, Regards, Hendrik Greving
