I consider this to be less readable than the peep2 way to do it,

Thanks a lot for ur help. can u give me a pointer to the origin of
peep2_reg_dead_p?
Do you mean the source code? A hint: grep ^func_name *.c will get to it
for every function in gcc.
In this case it is in recog.c, look at peep2_reg_dead_p but also
peep2_regno_dead_p. There are other peep2_* functions you may use.
