All patches for achieving this is currently being upstreamed and reviewed.
http://lists.llvm.org/pipermail/llvm-dev/2017-February/110097.html
There will be instructions on how to do this and the unofficial llvm
mingw-w64 build bot will be switched over to this soon.
Just bare with me for a week or so to get everything reviewed and in tree.

Best,
Martell

Re: [Mingw-w64-public] [PATCH] intrin-impl.h: Guard all intrins definitions by __has_builtin.

2017-02-17 Thread David Grayson

If the compiler has a builtin for the intrinsic, why would mingw-w64
still provide a prototype for it?  It seems like it would have no
benefit and be likely to just cause compiler errors in the future.

Thanks, but I'd be more interested in documentation how to get cross
