hi Erik,
Yes 8 supports VSX (128-bit SIMD, 4x single precision), and as far as I can
tell just a few extensions over the 7's VSX ISA.
I was able to build PoCL on a Power 8 machine but haven't had time to work
out the test failures. I'd be interested if you can explain a little more
about what other things required testing (apart from the VSX instruction
set).
Thanks,
Marmaduke
