Actually, HiPE *is* available for AMD64 machines. (We have not
advertized this much since we have been quite busy lately.)

Get the

	otp-20040705-1407.tar.gz

snapshot from 

	http://www.it.uu.se/research/group/hipe/snapshots/

compile it, and you will see something like:

	Erlang (BEAM) emulator version 5.4 [64-bit] [source] [hipe]

when you start the system. We are not aware of any problems in the port.

A paper describing the internals of the port, titled "HiPE on AMD64",
will be presented at this year's ACM Erlang Workshop and is available
at:

Enjoy!
