Thanks. Good catch. Installed.
It turns out that code will need a little more work. After some discussions
with rth I think the current way we split for ppro is not what we want to do.
My docs showed a reg->reg move as 2ups, which is incorrect. A reg->reg move
is a single uop. This changes how we want to generate code for some shifts
on the PPro.
