Description Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2017-06-26 21:20:05 UTC 
As figured out in #615754, with slotted LLVM now it is possible to install a newer LLVM slot without matching clang version. This makes the logic used in the eclass fail. The package in question locates llvm-config for the newest supported LLVM version rather than the one having clang.

What I'm thinking of is adding:

  LLVM_NEED_COMPONENTS='clang'

which would cause the eclass to consider only LLVM versions with matching clang version. For detection, we can check if $prefix/bin/clang exists.

This is now solved by llvm_check_deps().
