But this is only true for a pure x32 system. If you have any applications that need to be 64-bit (ie, anything that is going to need more than 4GB of address space, which is very different from needing more than 4GB of RAM) then you need to have two copies of your libraries and suddenly your memory benefits have entirely vanished. So, overall, x32 is only really beneficial for embedded platforms rather than general purpose ones. As Josh says, if there's sufficient interest then it could potentially be implemented as a separate architecture and spend some time in secondary, but I don't know that there'd be a huge benefit to Fedora to spend much time on it. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
