; This testcase should need to spill the -1 value on both x86-32 and x86-64,
; so it shouldn't use pcmpeqd to materialize an all-ones vector; it
; should use a constant-pool load instead.
;
; RAGreedy defeats the test by splitting live ranges.

; Constant pool all-ones vector:
; CHECK: .space 16,255

; No pcmpeqd instructions, everybody uses the constant pool.
; CHECK: program_1:
; CHECK-NOT: pcmpeqd
