[Qemu-devel] Hand written code generator #2

[Paul Brook]

I've made available a new version of my hand-written code generator for qemu. 
The patch is getting rather large, so I've put it on a web server to avoid 
spamming the list:
https://nowt.dyndns.org/patch.qemu_qop.gz

In principle it's very similar to the previous patch. The main difference is 
that it now supports all target architectures, including 64-bit targets.

The i386 changes have been tested by booting knoppix and win2k and win98.
x86-64 tested by booting a debian amd64 install cd.
ppc chanages tested by booting a debina install cd and running nbench under 
ppc-user.
My sparc debian cd doesn't boot under qemu (stops responding just after 
loading the kernel). Does anyone have any images I could use for testing 
sparc emulation?

To support 64-bit targets each qreg now has a "mode" which determines its 
size. 64-bit qregs can be implemented using pairs of host registers on 32-bit 
hosts, or single registers on 64-bit hosts.

ppc and sparc targets only have nominal support. I've done the bare minimum 
needed to make them work. Arm is still the only target that really takes 
advantage of any of the new functionality.

Next on my todo list is support for ppc and x86-64 hosts.
