--- Comment #13 from Marc Dietrich <marvi...@gmx.de> ---
gcc/clang development is fast and also the mesa supported version numbers of
compilers are increasing. So this is a fast moving target. That said, I
currently use the _target_ attribute of gcc (not supported by clang yet AFAIK),
and add a #pragma target:

That works fine for gcc and clang so far for me. Not sure if this is a working
solution for everyone.
