Hi Clang folks,


I'd like to know the status of Clang support
in the Linux mainline.
Still a work in progress. You still need to use the LLVMLinux patches on top of mainline to get it to work. We're upstreaming those patches as fast as we can.

I can see some "clang" specific parts in makefiles,
so I guess Clang is already supported to a certain extent.
Some of the required parts are there. But mainline currently won't compile out of the box with clang.

I just tried to build with "HOSTCC=clang CC=clang"
but it would not work.

Is there any tips I am missing here?
Try building from our kernel repo listed on http://llvm.linuxfoundation.org

Thanks,

Behan
