/*
    Note, that there are really 3 APIs:

    mips, mipsel:
      O32 ABI, ILP32, "long long" in a "aligned" even-odd register
      pair, 4 argument registers

    mipsn32, mipsn32el
      N32 ABI, ILP32, but with 64 bit wide registers, and "long long"
      in a single register, 8 argument registers

    mips64, mips64el
      N64 ABI, LP64, 8 argument registers

    where O32, N32, and N64 are the ABI names.  ILP32 means that
    (I)int, (L)long, (P)pointer are 32bit long. LP64 means that
    long and pointer are 64bit long.  "el" denotes if the ABI is
    little endian.

    N32 is different from 032, in the calling convention.  Arguments
    passed as 64bit (long long) reference, and there are 8 of those.
    O32 is the one closest to "normal" GNU/Linux on i386.

    It's a bit more complex. MIPS spans probably the largest
    performance range of any CPU family, from a 32bit 20 MHz
    Microcontroller (made by Microchip) up to a 64bit monster with
    over 5000 CPUs (made by SiCortex).  Obviously, only the 64bit
    CPUs can run 64bit code, but 32bit code runs on all of them.

    The use cases for the different ABIs are:
    - O32: Most compatible, runs everywhere
    - N32: Best performance on 64 bit if a large address space isn't
           needed.  It is faster than O32 due to improved calling
           conventions, and it is faster than N64 due to reduced
           pointer size.
    - N64: Huge address space.

    Currently (end 2007) Debian GNU/Linux only supports O32
