[Qemu-devel] What 64-bit CPU targets dominate in the future?

[Qemu-devel] What 64-bit CPU targets dominate in the future?

[J.C. Pizarro]

Hi people,

I'm looking for simulators of 64-bit processors for my 32-bit PC and
i've found one.

"qemu-system-x86_64" works simulating a x86-64 linux as slamd64, ubuntu, etc.

http://fabrice.bellard.free.fr/qemu/status.html indicates that x86-64
is OK for System emulation but is not supported for user emulation.

The problem is that the x86-64 ISA is too complex to develop i an
aplication that generates assembler or machine code like CacaoJVM,
JCVM, Flex, ...
x86-64 is CISC and not RISC. It will be easy if the 64-bit CPU is RISC.

I don't know what 64-bit CPU that will dominate in years 2008 .. 2013.

I'm not sure if PearPC or PSIM simulates PowerPC64 ISA but the
"Full-System Simulator for IBM PowerPC 970" said that it does but it's
closed source.

I'm not sure if Sulima simulates Sparc64 ISA from
http://ccnuma.anu.edu.au/sulima/0.4/sparc-sulima-0.4.tar.gz but it
goes to v0.4 version, not v1.0 :(

The IA-64 CPU is monstruous and too complex because there aren't known
open source applications that target IA-64. I don't know if that
simulator exists or not.

After talking, my question is:

What popularity of CPU will dominate in the years 2008 .. 2013? By example,
1. x86-64: 75%
2. ppc64: 15%
3. sparc64: 5%
4. others: 5%

Any opinion to the respect?

Sincerely yours, J.C.

AFAICS this has nothing to do with qemu.
Please don't post random unrelated questions to this list.

You've already been told the same thing on some of the other lists you posted 
the exact same mail to.
