Hi all!

I'm trying to cross-compile FreeBSD kernel with clang for ARM, but 
currently I have some troubles with it. Main is:

Clang uses external assembler and invokes GCC with some really specific 
flags, that aren't supported by GCC (like -fformat-extensions).

As base I used this guide:
http://people.freebsd.org/~cognet/arm.html

So the question is, had somebody tried to cross-compile FreeBSD kernel 
with clang for ARM? I would glad if somebody ready to share such 
experience ;-)

Thanks!

-Stepan
