GCC Maintainers:
The vec_reve builtin test builtins-3-vec_reve-runnable did not have a
minimum Power processor specified. The thought was the instructions for
the builtin were available on all the older processors. Unfortunately,
it turns out the builtin does require vsx hardware (-mvsx option). Bill
Schmidt said that the minimum platform that the builtins need to be
supported on is Power 7. The following patch sets the minimum platform
as Power 7.
Please let me know if the following patch is acceptable. Thanks.
Carl Love
