I think the libclc build failure is due to a change in llvm's headers; see <https://reviews.llvm.org/D26502>.

I had the same build failure, but libclc-0.2.0_pre20170929 builds ok for me.

Yep, sounds like mixing stable and ~arch. If you need ~arch LLVM, please use ~arch dev-libs/libclc as well.

@x11, is it fine to stabilize libclc-0.2.0_pre20170929?
Comment 6 Matt Turner gentoo-dev 2017-12-06 16:59:55 UTC 
Fine with me
