The ARM bits are OK by me, you'll need someone else to sign off on the other
bits.
One thing we did consider in the original implementation was whether the
"movmisalign" patterns should be renamed. In the ARM scheme describing these
as misaligned references it somewhat misleading. Instead we have "opaque"
vector transfers (mov<mode>) and array data transfers (movmisalign).
It's probably not worth the pain of renaming stuff, but I suggest adding
commentary in the movmisalign section of tm.texi.
