Expected Results:  
build 

if i modify the llvm-9999 and remove all clang coincidences from everywhere compiles just fine and works as much a mesa care, not sure if clang and libclc works tho, since i don't use opencl part of mesa yet
Comment 1 Bernard Cafarelli gentoo-dev 2015-09-03 13:51:42 UTC 
Cleaning old llvm/clang ebuilds, as this was about a problem in live ebuild 2 years ago.

Don't hesitate to reopen if you still have this problem!
