[pypy-dev] Readiness of asmgcc for x86_64 linux?

[Gary Robinson]

Thanks for your response Alex... I have a couple follow-up questions:

Is this a matter that is getting PyPy developer attention, or is expected to in the relatively near future?

That's great news. Is there any estimate of when a fairly stable beta will be available?

Thanks!
Gary

The last thing Jason Creighton wrote on the subject that I can find, from Aug 13, was: "...the bottom line is that the main goal of my GSoC was accomplished: A working 64-bit PyPy JIT. Hopefully I'll be able to complete asmgcc-64, and make the JIT even faster..."

I see "r77223 - in  pypy/branch/fast-forward/pypy/module/_multiprocessing: . test" in the svn commit log, dated Tuesday of this week (http://permalink.gmane.org/gmane.comp.python.pypy.cvs/29865)... I'm hoping that means it's going to be supported soon? That would be really great.
