Thanks for the comments! Here is a second go-round at the patch with
improved documentation. I'm happy to change the wording if it can be
further improved.
Thanks,

Hi,
This patch adds flavors of the -maltivec option that allow explicit
specification of vector element order. This is independent of the
target endianness in effect. The primary use of this is to allow
specifying big-endian vector element order when targeting a
little-endian processor, which ai
