[llvm-dev] How to cross-compile for ARC in clang?

[Pete Couperus via llvm-dev]

Hello,

Thanks for the note here.
We put up a patch a while back for enabling the ARC target in clang, the compiler:
https://reviews.llvm.org/D43089

(I didn't realize this was from so far back until looking now).
The current backend has really only been exercised through C.
So, applying this patch should help.
We also have some driver changes which can be used to integrate with the ARC GNU toolchain.  The sticky point is C++ support.

Pete

Oh, that's what I was afraid of.
So there is definetly no way to compile for ARC?
If so, should I write ARC.h(.cpp) in lib/Basic/Targets in order to make it work?

I suggest you reach out to the contributors of the LLVM ARC backend (CCd) to ask about their plans to contribute target support for Clang.  I believe they have work in progress, but I don't know their plans for contributing it.

Tom.

I couldn't find any trace of ARC in the Clang source, so I suspect
it's only supported by LLVM at the moment.

Cheers.

Tim,
