In the file you mentioned, the usage is however limited to the `dump` method, and not to the `print` method as per the previous PR. As I was anticipating, it's fine by me as long as it does not impose any build type assumption to downstream users (and this PR fixes such a problem), but let's also hear others people opinion on this.

Well, I don't think naming matters here. What matters is that `void dump(raw_ostream &OS) const;` is defined in cpp file,  i.e. including `MCAsmMacro.h` in debug build and linking with a release LLVM would be the same problem, right ?
