honestly, depends a lot on who will do it. basically, I see 3 parts: 1) The Stack VM 64bits 2) The Pharo image 64bits. 3) NB-FFI 64 (No point on having a VM who cannot talk with the outside world) a future task could be create a JIT, but I complete ignorant on how difficult/possible is that :) To compile the stack vm in 64 bits is not difficult, but there is a lot of small tweaks to make... so I think 1 man-month should be enough . To produce a 64bits pharo image we need an objecttracer.... and Guille says with ObjectSpaces is a lot easier... but again, it has to be done... I think another month should be enough. ... and with NB-FFI 64, no idea, but AFAIK is almost there (Camillo knows more there) also, 1 and 2 are vital, and we can tune 3 with the VM+Image working. That's my (very general) opinion. Esteban On Jun 27, 2013, at 2:16 PM, Stéphane Ducasse <stephane.ducasse@inria.fr> wrote:
Hi
we got this discussion about the VM on 64 bits so do we try to take the opportunity to get a crowdsource donate button for it?
Esteban/igor what is your estimate for such task?
