Trying to build ruby-2.3.0 with clang 3.9.0 (trunk 267338). So far, I've been
unsucessful:

Clang was compiled with cmake options which can be found at:
https://github.com/elkrejzi/system-management/blob/master/bootstrap/039-llvm#L13
It was compiled with GNU GCC version 6.0.1 20160421 (prerelease).
Ruby was compiled with ./configure --prefix=/usr --disable-static
--enable-shared --disable-install-capi, while also using CFLAGS="-march=skylake
-fomit-frame-pointer -Os -pipe" and clang as a compiler.
clang 3.8.0 works fine (with addition of -mno-avx512f to CFLAGS because 3.8 has
-march=skylake which targets AVX-512 systems which this CPU doesn't have).
Mentioned files are attached. Let me know if you need more info
