Yes, on Alpha and Itanium machines.
On Sparc, Mips and PPC, it should be possible to compile the bytecode
interpreter in 64-bit mode, but the native-code compiler still
generates 32-bit code. That might change if there is enough demand,
e.g. for the new G5 machines.
The x86-64 port of OCaml will be fully 64-bit once it is completed,
that is, shortly after I get access to one of these machines.
However, given the lack of "testdrive" programs for the x86-64, I have
no idea when I'll get a shell account on one of these toys.
