[PATCH] D13263: Addition of __attribute__((pass_object_size)) to Clang

[George Burgess IV via cfe-commits]

george.burgess.iv added a comment.

Rebased + made Windows `pass_object_size` mangling scheme more like Itanium’s.

I can’t find an explicit extension point here <http://www.agner.org/optimize/calling_conventions.pdf>, so the current approach is to mangle `void foo(void *__attribute__((pass_object_size(0))));` as if it was `void foo(void *, ::__ext::__pass_object_size0);`, and hope that there’s never a collision. Suggestions for better ways to do this are welcome. :)
