#flipcode

Hi,

I wondered where flipcode might pop up again.

I recently decided to rearchitect my renderer (in the same ballpark as indigo, but still in extended hacking) for the twentieth time and make it 64 bit only. My 64 bit machine is in for some repair (read: replacing yet another faulty asus motherboard) and so I\'ve got a bit of dead time to think about whether moving to 64 bit is a good idea and if so the kind of memory issues that might crop up.

Has anybody any experience of the issues/benefits of porting this kind of software to 64 bit?

Ideally you shouldn\'t have any issues, but that depends how good your code is =)

The only real advantage you get from going 64-bit with your software is the ability to use >4GB of RAM without the hassels of using physical address extensions on 32-bit CPUs. Although I think AMD gives you a few more 64-bit only registers to play with, but I could be wrong on that.

As for issues, the only thing you gotta watch out for is your pointer sizes. At some point in the code you could be assuming that a certain pointer is only a 32-bit integer, which may cause issues for you.
