[cfe-dev] How to add new target?

[Artur Pietrek]

Hi all,
First, since it's my first post here, I'd like to say hello!

I've started to write LLVM backend for our processor some time ago and I can
produce correct (most of the time ;) ) code.
What I need now, is to add my target processor to cfe - I've already added a
class to lib/Basic/Targets.cpp.

Could anyone write in points what should be done in Clang to add new target
support (especially target specific builtins) and how to force clang to act
as a cross-compiler?
Thanks a lot for your help

Artur
