Warning on custom attribute

Hi list,

I follow all the steps of http://clang.llvm.org/docs/InternalsManual.html#how-to-add-an-attribute
tutorial on ‘how to add an attribute on clang’ but still a get an ‘unknown attribute’ warning.

The generated file (AttrList.inc) contains my new attribute.
Therefore, I assume that I need also to attach the new attribute to target
(I support a different one than the built-ins).
But, not sure if I make the correct changes. I’d like to ask your help on this.

Thank you in advance,

-IS
