[LLVMdev] Fwd: Building VMKit

[nicolas geoffray]

Hi Joshua,

If you can get a running 32bit system, I'd suggest you do so, as you'll get
up to speed right away. I can't test VMKit on a 64bits machine, and I have
been aware that there are some compilation/execution problems. Besides, the
current GCs of VMKit do not work on 64bits (neither MMTk nor GCMmap2).
