; 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

entry:

  store float %conv, float* getelementptr inbounds (%struct.A, %struct.A* @a, i32 0, i32 0)

; CHECK-NOT: Unexpected setcc expansion!
