; RUN: llc -verify-machineinstrs < %s | FileCheck %s
; This test case used to fail both with and without -verify-machineinstrs
; (-verify-machineinstrs would catch the problem right after instruction
; scheduling because the live intervals would not be right for the registers
; that were both inputs to the inline asm and also early-clobber outputs).
