Yep, with 3.1 9vx runs fine for an hour already. However, I want to

I mean, why they aren't joined together? What the difference between them?

9vx is very nice, I use it all the time, but it is also pretty easy
for me to drive it into a corner such that simple commands don't have
repeatable results -- memory corruption problems start to appear. If
you are having troubles, it is not necessarily your fault, and you may

If you're on linux, you should consider kvm + kvmtool + plan 9.
vx32 is incomplete. It has many problems. Nobody's had the time to
really fix it. It's nice that it works but you should not assume that
it's a solid piece of software; it's not.

registers are dead on entry to a function, so there's no point in saving
particular values, because they won't be used. on an amd64, however,
the kernel should
reset the FP-used flag, to cause the preset values to be set in the high FP

However, as it won't work on my laptop natively, i'm forced to use 9vx
