Hello All.
Is anybody know why `dead_or_set_p' returns 1 for insn 1
and 0 for insn 2 ?
Is this right ?
(insn 1 0 2 (parallel[
(set (reg:QI 47)
(mem:QI (reg/v:HI 41) 0))
(set (reg/v:HI 41)
(plus:HI (reg/v:HI 41)
(const_int 1 [0x1])))
] ))
(insn 2 1 0 (set (reg:QI 47)
(mem:QI (post_inc:HI (reg/v:HI 41)) 0)))
Denis.
