The actual LLVM integration patch

[Chris Lattner <sabre at nondot dot org>]

I threw the current version of the patch up here:
http://nondot.org/sabre/llvm-gcc-4.0-patch.tar.gz

This is a patch vs the Apple branch as of a few weeks ago.  The diff is in 
gcc.patch.txt, the new files are included in the tarball.

Note, there are not enough caveats in the world to include with this.  :) 
I literally ran to work, grabbed the diff and am uploading it.  The patch 
has tested (with Apple code, not with dejagnu) at various points with 
'--enable-languages=c,objc --enable-llvm'.  It's entirely possible that I 
was in the middle of something Friday and I forgot about them, and it is 
very clear that the patch is incomplete (was not intending to make it 
public for a month, so there are still FIXMEs and other missing pieces). 
Also, a lot of the changes in objc-act.c are LLVM-independent speedup 
patches I've fed to Fariborz separately for inclusion in mainline.

However, it should at least give the list some concrete idea of what I'm 
talking about.  :)  If you have specific criticisms of the patch, I 
welcome the feedback, please send it to me privately.

The main part of the translation process is in llvm-convert.cpp.

Oh, if you want to test it, you have to download and build an LLVM 
tarball, and hack LLVMBASELIBPATH in the gcc/Makefile.in to point to the 
directory.  An --enable-checking build uses the debug libraries, a normal 
build uses the release LLVM libraries.

Clearly there is a lot of work to do on the patch, so don't go too hard on 
me. ;-)  Again, suggestions for improvements are welcome.
