; When we convert an `i64` to `f32` on 32-bit PPC target, a `setcc` will be
; generated. And this testcase verifies that the operand expansion of `setcc`
; will not crash.

%struct.A = type { float }

@ll = external local_unnamed_addr global i64
@a = external local_unnamed_addr global %struct.A

define void @foo() local_unnamed_addr {
entry:
  %0 = load i64, ptr @ll
  %conv = sitofp i64 %0 to float
  store float %conv, ptr @a
  ret void
}

; CHECK-NOT: Unexpected setcc expansion!
