You can also get application with hand-coded cache optimizations
that are even harder, if not

Have you always executed an eieio or sync when you get here, or
do you just not allow direct access to I/O devices? Other context
synchronising insns are not enough, they do not broadcast on the
bus.
There is no device
Nice patchset. Some comments on the emulation part:

You mean EIEIO.

Cool, thanks for looking though them!

Probably, yeah.

There are generic parts of PowerPC that can be shared across all
implementations and specific parts that only apply to BookE or desktop PPCs.
This patch adds emulation for desktop specific opcodes that don't apply
to BookE CPUs.
