--- Comment #5 from Adam Stylinski <kungfujesus06 at gmail dot com> ---
Apologies for my ignorance by the way, I've been mostly spoiled lately with=
 x86
and aarch64 which handle this to some degree for you in the uarch.  I wrote
this code a long time ago when I was just getting familiar with Altivec, so=
 I'm
well aware what I was doing could have been completely wrong and/or stupid.=
  At
the very least I could have done more to pipeline the unaligned loads so th=
at
the previous vector load for the second half was reused (I don't think GCC =
can
do this for me).=20=20

I'm hoping people who are intimately familiar with the ABI and heap layout =
of
big endian POWER4 can clarify if I'm wrong, the library is wrong, or both.
