3; This LL file was generated by running clang on the following code:
4; D:\test.cpp:
5; 1 void foo();
6; 2
7; 3 static void bar(int arg, ...) {
8; 4   foo();
9; 5 }
10; 6
11; 7 void spam(void) {
12; 8   bar(42);
13; 9 }

15; The bar function happens to have no lexical scopes, yet it has one instruction
16; with debug information available.  This used to be PR19239.
