[Fwd: Latest version of CPU emulator] (fwd)

[Geert Uytterhoeven]

Perhaps Gabriel's 486SX emulator can be included as an optimization?

Geert and rth,

This is unrelated to Linux kernel but I hope you can still help.  I am
trying to drum up developer interest in WINE -- specifically the
interest of coders on non-x86 platforms.  Do you think you could perhaps
forward this message to pertinent lists?  (I am no longer on axp-list,
and am not on the m68k/ppc/etc lists)

WINE is on the verge of being able to run Win16 and Win32 programs on
non-x86 platforms.  Ulrich Weigand, a WINE hacker, has completed x86 CPU
emulation support, including full x86 instruction set through P-III and
all addressing modes.  The only thing that keeps his CPU emulator from
running WINE on the PPC today is issues that he can't test himself: 
endianness and alignment and other processor differences.

Hopefully the major work is done.  The CPU emulator has
processor-neutral code to decode and emulate each instruction from 8086
through P-III.  All that is left is a need for developers on non-x86
platforms to pick up the reins and stomp out the remaining issues.

Ulrich's latest code was just posted to wine-devel, at
http://www.integrita.com/cgi-local/lwgate.pl/WINE-DEVEL/archives/1999-08/date/article-315.html 
I looked through it, and it is very readable.

Regards,

	Jeff
