Exactly.. this is the same thing as calling dead_or_set_p(insn, operands[0]). If it can be done by dead_or_set_p, why use peep2_dead_reg_p? Other ports also support the use of peep2_dead_reg_p instead of dead_or_set_p. What is the basic difference between the two? I mean, there must be something the former can do which the latter can't. Please correct me if i am wrong. Thanks in advance, Ashwin.
