Yes!  Do you have a machine to contribute to the build/test?  I'm up for
helping to fix problems.

OK, I will start pegging away at it.

Rana,

I think now it's just a right time to start this work. It would be good if
you do preliminary examination of which areas need to be fixed for 64 bit
Windows in VM/JIT. I don't think there will be many problems eith enabling
on the JIT side - so far optimizations which do not work on EM64 (for
example those requiring fs:14 for TLS access) are turned off there.

Thanks,
Pavel

Re: [general] Winx86 platform support

[Rana Dasgupta <rd...@gmail.com>]

This port would be really good to have, but not urgent. Obviously, the
biggest change is in the JIT. At the moment, I think that we should focus on
stabilizing and performing on the 3 major platforms we are functional on.
The IPF port is also in progress. However, with the Vista releases early
next year? ( 32 and 64 bits ), 64 bit Windows will be a major platform and
we will need to be on it. I am going to start going thru DRLVM to identify
functional areas and implementation that need to change, play around with
the Microsoft 64 bit toolsets( ML64 assembler, CL, LINK, Visual Studio 64
bit ) etc. and start putting together a Windows64 porting guide on the Wiki.
Or is it too early to do this?

Thanks.

Re: [general] Winx86 platform support

In 32 bit mode or 64 bit mode? We are not ported/functional yet on 64 bit
Windows for exception handling, JIT etc. No [fs:14] for TLS access, windows
handles are 8 bytes, all the inline asm{} needs to go away, most data types
are different...More changes than Linux 32 -> Linux 64. I would think that
the work involved would be somewhat similar to an IPF port. Certainly worth
doing though.

we do want to support this platform, but need an installed 64bit windows 
machine to work on - or at least someone to have it and give us feedback.
