(modulo > the requisite OS support etc., limits with address lines and so on) 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. - Xavier Leroy ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
