; This test is based on an llvm-stress generated test case with seed=449609655

; This test originally failed for MSA with a
; "Comparison requires equal bit widths" assertion.
; The legalizer legalized ; the <4 x i8>'s into <4 x i32>'s, then a call to
; isVSplat() returned the splat value for <i8 -1, i8 -1, ...> as a 32-bit APInt
; (255), but the zeroinitializer splat value as an 8-bit APInt (0). The
; assertion occurred when trying to check the values were bitwise inverses of
; each-other.
;
; It should at least successfully build.
