[PATCH] D22045: [X86] Support of no_caller_saved_registers attribute (Clang part)

[Matthias Braun via Phabricator via cfe-commits]

MatzeB added a comment.

Just out of interested: I can see how `__attribute__ ((interrupt))` is useful, but in what situations would you use `no_caller_saved_registers`?
