vec-mul is an execution test, but it only requires a powerpc_vsx_ok
effective target, which is enough only for compile tests.  In order to
To check for runtime and execution environment support, we need to
require vsx_hw.  Make that a condition for execution, but still

Regstrapped on ppc64le-linux-gnu, also tested on
x86_64-linux-gnu-x-ppc-vx7r2 (no vsx execution support)
Ok to install?  gcc-12?  gcc-11?

More tolerance and less prejudice are key for inclusion and diversity
Excluding neuro-others for not behaving ""normal"" is *not* inclusive

Nit: It's useless to check powerpc_vsx_ok for vsx_hw, so powerpc_vsx_ok check
can be moved to be with ! vsx_hw.

OK with this nit tweaked, thanks!

Thanks, here's what I'm pushing momentarily...


ppc: testsuite: vec-mul requires vsx runtime

vec-mul is an execution test, but it only requires a powerpc_vsx_ok
effective target, which is enough only for compile tests.  In order to
check for runtime and execution environment support, we need to
require vsx_hw.  Make that a condition for execution, but still
perform a compile test if the condition is not satisfied.
