--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
During expand:
(insn 20 19 21 (set (reg:V2DF 149)
(unordered:V2DF (reg:V2DF 128 [ vect__7.7 ])
(reg:V2DF 128 [ vect__7.7 ]))) -1
(nil))
Which is correct.
after combine:
(insn 26 21 27 3 (set (reg:V2DF 154)
(unordered:V2DF (reg:V2DF 144 [ vect__7.8 ])
(reg:V2DF 144 [ vect__7.8 ]))) 1138 {vector_unorderedv2df}
(expr_list:REG_DEAD (reg:V2DF 144 [ vect__7.8 ])
(nil)))
So basically the splitter here goes wrong:
; For ltgt/uneq/ordered/unordered:
; ltgt: gt(a,b) | gt(b,a)
; uneq: ~(gt(a,b) | gt(b,a))
; ordered: ge(a,b) | ge(b,a)
; unordered: ~(ge(a,b) | ge(b,a))
(define_insn_and_split
Someone else needs to look into making sure these are valid for trapping math
case ...
