[Openmp-dev] [cfe-dev] CMAKE_INSTALL_PREFIX vs -fopenmp and clang search library search path

[Carlo Bertolli]

Hi

I vote for -lllomp, i.e. lib name libllomp.a.

There is already a (perhaps unofficially named) LOMP library around (which
can be used as openmp runtime for clang) and this would make some
discussion hard to understand. See references to it here:

Cheers

-- Carlo
