[Qemu-devel] [PATCH 0/4] target-m68k areg writeback

[Richard Henderson <rth@twiddle.net>]

Here's the patch I almost wrote in the email, followed by
a cleanup that allows cmpm to be written "nicely".

I can test this to some extent with the coldfire kernel,
but of course coldfire can't excersise any of the tricky
edge cases that m68000 can.

I'm particularly interested in edge cases like

	mov.b	a0@+, a0@+
	movea	a0@+, a0
	movea	a0, a0@-

The first two are not really useful and likely not show up
in normal code.  The third may well do so; I think our
current code gets it wrong, but this will get it right.
