Subject: [Qemu-devel] [PATCH 00/52] 680x0 instructions emulation
Date: Wed,  4 May 2016 22:11:40 +0200	[thread overview]
Message-ID: <1462392752-17703-1-git-send-email-laurent@vivier.eu> (raw)

This series is an update of the series I sent last year:

https://lists.nongnu.org/archive/html/qemu-devel/2015-08/msg01049.html

Based on the series sent by Richard Henderson:

https://lists.nongnu.org/archive/html/qemu-devel/2015-08/msg01793.html

It is in fact a major rewrite. Most of the instructions are now inlined.

This series doesn't break Coldfire support. I've checked the following
image can always boot:

http://wiki.qemu.org/download/coldfire-test-0.1.tar.bz2

Only non-privileged instruction are implemented.
680x0 FPU instructions are not implemented.

So this is not enough to run 680x0 binaries. I will send a new series
with FPU emulation once this series is merged.
