>Description:
It contains the code:

  /* FIXME: cagney/2002-09-13: This is just soooo bad.  The MIPS
     should have a pseudo register range that correspons to the ABI's,
     rather than the ISA's, view of registers.  These registers would
     then implicitly describe their size and hence could be used
     without the below munging.  */
  if (lval == lval_memory)
    {
      if (regno < 32)
        {
          /* Only MIPS_SAVED_REGSIZE bytes of GP registers are
             saved. */
          return read_memory_integer (addr, MIPS_SAVED_REGSIZE);
        }
    }

  return extract_signed_integer (raw_buffer, REGISTER_VIRTUAL_SIZE (regno));
