    Yes, on OpenRISC we declare it in ptrace.h (see

    I'm really not an expert on GDB, but I believe it can use either the
    PEEK/POKE functions to access regs, or it can use GET/SETREGS; it's an
    architecture-dependent configuration. I think the second variant can
    be easily modified to become GET/SETREGSET instead, and the PEEK/POKE
    variant wouldn't be needed at all.
