[Qemu-devel] MIPS exception number limits?

[Wei-Ren Chen]

Hi all,

  Wondering why MIPS limits exception number less then 0x100,
you can see such example in function do_raise_exception_err
(target-mips/op_helper.c). See below,

static inline void QEMU_NORETURN do_raise_exception_err(CPUMIPSState *env,
                                                        ...
{
  ...

#if 1
    if (exception < 0x100)
        qemu_log("%s: %d %d\n", __func__, exception, error_code);
#endif

  ...
}

  Anyone can help confirm this, stated in what spec? Also, do we
need "#if 1 .. #endif"? Thanks for help. =]  

Regards,
