[llvm-commits] [patch] Add the returns_twice attribute

[Rafael Ávila de Espíndola]

The attached patch reuses the hotpatch attribute (which Charles Davis
says is unused) to create the returs_twice attribute. This will be used
to implement the C attribute with the same name.

It is needed by valgrind, since it has its own setjmp like function.

See PR11038 for more information.

Is it OK?

Cheers,
Rafael
