Description Sheng Yu 2022-06-12 19:09:41 UTC

Under LLVM/clang 14, _tc-has-openmp return failed because it needs extra -lm in order to compile.

undefined reference to fmaxl
undefined reference to logbl

 * Your current compiler does not support OpenMP!
 * OpenMP support in sys-devel/clang is provided by sys-libs/libomp.


Reproducible: Always

See bug #794481, I assume the stance hasn't changed (albeit it is becoming a long standing issue).
