Hi Folks,
on powerpc-darwin9 (m64) ...
FAIL: experimental/simd/standard_abi_usable.cc -maltivec -O2 -Wno-psabi

It seems that testing __ALTIVEC__ is not sufficient, since the tests need
an ISA that supports double ops?
I’m not sure if the conditions need amending, or if the simd suite is just
unusable on a machine with only support for 32b float/int vector ops?
(depending on the answer to that, we need to figure out the amendment, or
skip the suite for < power7)
thanks
Iain
