[Qemu-devel] [PATCH 00/11] Proposed format for m68k flags |
Date: |
Fri, 14 Aug 2015 07:59:15 -0700 |
As promised a couple of days ago, with the addition of CC_OP_CMP,
which wasn't in the text of my proposal the other day. From the
looks of the generated code, I believe this is ideal.
The following is based on Laurent's 8/30 Update cpu flags management.
FWIW, there's something in the last patch here that breaks the
coldfire kernel I've been testing (it may even be a bug in tcg;
the problem only appears well into the boot process). But I'm
about to go away for the weekend and still wanted to include it
to show what can be done.
For convenience, the complete tree pushed to
git://github.com/rth7680/qemu.git tgt-m68k
