The old one is
(define_expand "umaxv8hi3"
[(set (match_operand:V8HI 0 "register_operand" "=x")
(us_minus:V8HI (match_operand:V8HI 1 "register_operand" "0")
(match_operand:V8HI 2 "nonimmediate_operand" "xm")))
(set (match_dup 3)
(plus:V8HI (match_dup 0) (match_dup 2)))]
"TARGET_SSE2"
The new one is
(define_expand "umaxv8hi3"
[(set (match_operand:V8HI 0 "register_operand" "")
(umax:V8HI (match_operand:V8HI 1 "nonimmediate_operand" "")
(match_operand:V8HI 2 "nonimmediate_operand" "")))]
"TARGET_SSE4_1"
I am not able to generate 2 different templates with the same name,
umaxv8hi3, depending on TARGET_SSE4_1 or TARGET_SSE2.
