I agree that it's limited.  As for MC, it will need to handle these strings
anyway since this is an existing LLVM feature (coming from gcc originally)
that needs to be supported.

Because magic globals need magic treatment, i.e. special logic in the code
generators etc.  Why add all this new stuff if an existing feature will do?

Ciao,
