; This test is added to provide test coverage for the 
; .cfi_sections .debug_frame intrinsic. It aims to make sure that for an X86_64
; output compiled with -fno-exceptions, no .cfi_sections .debug_frame is 
; emitted.

; RUN: llc --filetype=asm %s -o - | FileCheck %s
; CHECK-NOT: .cfi_sections .debug_frame
