My only experience with multi-ABI systems so far has been with MIPS64 Linux which, like x86-64, support 64- and 32-bit ABIs (actually, two different 32-bit ABIs simultaneously, for a total of 3). We chose to build all of userland with one of the 32-bit ABIs, and then provide 64-bit libraries for application developers who really wanted 64-bit of addressable memory for their apps. It looks like x86-64 Linux is doing almost the exact opposite. 64-bits is the default and 32-bit libs exist for compatibility. > I don't know.

That's one instance where 64-bit is useful: I expect > there are others. Ok, that's good to know. AG
