--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
And the:
Successfully matched this instruction:
(set (reg:CCZ 17 flags)
(compare:CCZ (and:QI (reg:QI 143)
(reg:QI 145))
(const_int 0 [0])))
Successfully matched this instruction:
(set (reg:QI 82 [ b_lsm_flag.26 ])
(and:QI (reg:QI 143)
(reg:QI 145)))
case should be rejected on the grounds that flags isn't dead at the last of
these insns and that clobbers of that reg are added when the second insn is
being recognized.
Segher, do you think you could have a look?
