------- Comment #3 from hjl at lucon dot org 2007-05-05 02:31 -------
The problem may be patterns like
[(set (match_operand:SI 0 "nonimmediate_operand" "=r,rm,r")
(plus:SI (match_operand:SI 1 "nonimmediate_operand" "%0,0,r")
(match_operand:SI 2 "general_operand" "rmni,rni,lni")))
(clobber (reg:CC FLAGS_REG))]
What if we replace (clobber (reg:CC FLAGS_REG)) with something more
reasonable like
(set (reg FLAGS_REG)
(compare
(plus:SI (match_dup 1) (match_dup 2))
(const_int 0)))
