Hi,
Some of the recently introduced Altivec tests pass for -mcpu=power8, but
fail to compile for older processor models. This is because the
vec_all_eq interface, when used with vector double arguments, maps to a
built-in that is only available on Power8 and later hardware. This
patch modifies the tests to avoid using vec_all_eq for vector double
arguments.
Bootstrapped and tested on powerpc64-unknown-linux-gnu with
-mcpu=power7, and on powerpc64le-unknown-linux-gnu with -mcpu=power8,
with no regressions. Is this ok for trunk?
David, this should clear up the recent failures on AIX.
Thanks,
Bill
