Hi, On debian lenny I'm playing with GCC trunk (4.4) to build a tri-ABI compiler on a lemote netbook (running gnewsense kernel and lenny userspace). My understanding is that lenny userspace is -mabi=32 (o32) and GCC and libc support abi=32,n32,64, the kernel being 64. n32 seems to be more performant than 32, do you know why it is not used by default? Is it unsupported on some hardware?
n32 and n64 are only supported on 64-bit hardware/kernels.There is a lot of 32-bit hardware out there (although I don't know how much is officially supported by Debian).
