llvm dev - Mar 2014 - [LLVMdev] Contributing the Apple ARM64 compiler backend

I just tried to apply the patches to the community clang and llvm tips and
there are conflicts.

Do you guys plan to rebase the patches?

I vote for importing the ARM64 backend into the public tree as soon as
possible.

Thanks,
Ana.

Indeed, getting #1 done (importing the ARM64 backend into the public tree)
right away seems the right thing to do.

Thanks,

There are new conflicts several times a day, on average. I rebased them on
Wednesday on top of svn 204791. If you want to try them out, it would be best to
roll back to that revision.

I’ll rebase them one more time when we commit them, but it’s such a moving
target (and takes a fair bit of work), that I’d rather wait until we’re ready to
commit.

There has been universal support for merging it in, so lets do it.  Please start
by commiting the llvm part (i.e. lib/Target/ARM64, tests, etc).  We should have
a similar discussion on cfe-dev to get those changes reviewed, and commit the
clang pieces when that settles out.

The libc++, compiler_rt, and lldb piece should be separately reviewed and
explained before they go in.

Thanks Bob (and everyone who worked on the apple arm64 backend!)
