; i386 test has been disabled when scheduler 2-addr hack is disabled.

; This testcase shouldn't need to spill the -1 value,
; so it should just use pcmpeqd to materialize an all-ones vector.
; For i386, cp load of -1 are folded.

; With -regalloc=greedy, the live range is split before spilling, so the first
; pcmpeq doesn't get folded as a constant pool load.
