The 64 bit processors have a 32 bit mode. 64 bit code has different
address sizes, so uses a different register set. That should be straight
forward to change. The killer is that 64 bit C calling conventions
differ between Windows and Unix. They are also more complicated than the
32 bit calling convension. If psyco generates functions on the fly then
allowing for that would become involved.

It can work in 32bit mode... as long as the binary is 32bit. On linux
and osx, you can run 32bit binaries on a 64bit system... along side
64bit apps. I think you can do it on windows too... but not as well.
For some things 64bit python is 4x faster for me... so 64bit python is
faster than psyco with 32bit psyco for some things. A complicated
world we live in ;)

oh good. But why can't something written for 32bit work on 64bit?
I thought that a higher bit number was backwards-compatible

However, recently other people are working on psyco.... so if
they get funded for 64bit work... it might happen too.
There's a new release of psyco coming out soon.

. .. . the author has no intention of updating Psyco to
support 64 bit
architectures. For 64 bit OSs, you're stuck with other
methods of
optimisation.
