    No - you need IRIX64, which means you need at least an R10k and an
    appropriate machine. This could be an Indigo2 with R10k or any Octane,
    but on O2 e.g. you're "limited" to N32 (even if R10k and R12k processors
    are available for it).

    And it's not always neccessary (or even a good idea) to use the 64Bit
    ABI, as it's not any "better" under normal circumstances. You'll need it
    if you're dealing with large amounts of data and require lots of address
    space. But usually N32 works perfectly well and has a smaller memory
    footprint.

    But I'm not sure if GCC can still create it. AFAIK this ABI is
    deprecated and exists just for backwards-compatibility. It shouldn't be
    used for new projects, especially as most additional libs are usually
    installed in N32-format.
