-; Test to ensure that a module containing both a NoDebug CU and one with
-; debug is handled correctly.
-
-; LLVM IR was generated the following way:
-; $ cat a.cpp
-; void f1();
-; __attribute__((always_inline)) void f2() {
-;     f1();
-; }
-; void f3();
-; void f4() {
-;     f3();
-; }
-; $ cat b.cpp
-; void f2();
-; __attribute__((always_inline)) void f3() {
-;     f2();
-; }
-; $ clang++ -flto a.cpp -g -c
-; $ clang++ -flto b.cpp -Rpass=inline -c
-; $ llvm-link {a,b}.o -o - | opt -O2 - -o ab.bc
-; $ llvm-dis ab.bc
-
-; Ensure we can successfully generate assembly, and check that neither
-; "b.cpp" nor "f3" strings show up (which would be in the .debug_str
-; section if we had generated any lexical scopes and debug for them).
