; 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.
