Have you used it or know people who have ? I am very curious about the experience and the details. Are there distributions that ship with libraries compiled with X32_ABI ?

  Ubuntu?

  Maybe some embedded systems distro have tried but as far as I know not any major distro. That would probably uncover quite a lot of bugs and require adaptations since lot of code assume Intel and compatible are either x86 or x86_64 and address memory accordingly. There are some people trying to port Archlinux to x32 but I really don't know the status. [edit] An one year old LWN article : http://lwn.net/Articles/548838/ http://lwn.net/Articles/548838/

  I seem to have /libx32 and /usr/libx32 (and they're non-empty too) on my Debian unstable system.
