[llvm-commits] Use of MVT::LAST_VECTOR_VALUETYPE in PowerPC target

[Dan Gohman]

Hello all,

While doing some experiments with vector ValueTypes, I noticed that
the PowerPC target uses MVT::LAST_VECTOR_VALUETYPE inconsistently with
the way it is declared. I don't have the resources to test PowerPC
changes, so I'm just sending this patch to the list in case anyone
who does is interested in it.
