Currently libclc doesn't respect CXXFLAGS. It gets them from running `llvm-config --cxxflags` (in configure.py). This behaviour may cause build errors, when LLVM was compiled by GCC with flags that not supported by clang++. Reproducible: Always Steps to Reproduce: 1. Compile llvm with gcc and have options not supported by clang++ compiler (`-mabm` for example) 2. Compile libclc 3. x86_64-pc-linux-gnu-clang-3.7: error: unknown argument: '-mabm'
Could you please attach emerge --info and the package build log?
Created attachment 414200 [details] emerge --info
I've already compiled llvm-3.7 without -mabm as a workaround... and forgot to save failed build.log. I've attached `emerge --info` only
It is probably best to report that upstream too, https://llvm.org/bugs/
