Actually this is a different issue than I orginally thought (just waking up).
(insn:TI 16 9 14 (parallel [
(set (reg:CC 74 6)
(unspec:CC [
(reg/v:V8HI 77 0 [orig:126 b ] [126])
(reg/v:V8HI 78 1 [orig:124 a ] [124])
(symbol_ref:SI ("*vcmpgtuh."))
] 173))
(clobber (reg:V8HI 90 13))
]) 666 {altivec_predicate_v8hi} (nil)
(nil))
(insn 14 16 20 (set (reg:V8HI 77 0 [orig:121 D.1927 ] [121])
(unspec:V8HI [
(reg/v:V8HI 77 0 [orig:126 b ] [126])
(reg/v:V8HI 78 1 [orig:124 a ] [124])
] 58)) 531 {altivec_vcmpgtuh} (nil)
(nil))
The instructions are not even alike in RTL.
