; RUN: llc -mcpu=core2 -mtriple=i686-pc-win32 -O0 < %s | FileCheck --check-prefix=X86 %s

; This LL file was generated by running clang on the following code:
; D:\test.cpp:
; 1 void foo();
; 2
; 3 static void bar(int arg, ...) {
; 4   foo();
; 5 }
; 6
; 7 void spam(void) {
; 8   bar(42);
; 9 }
;
; The bar function happens to have no lexical scopes, yet it has one instruction
; with debug information available.  This used to be PR19239.
