* mips-tdep.c (mips_print_register): Print integers using
print_scalar_formatted rather than duplicating all the CC_HAS_LONG_LONG and so on. (mips_push_dummy_frame): Use read_register_gen rather than using read_register and then putting it back in target format with store_unsigned_integer. If registers are more than 4 bytes, give an error rather than have some registers overwrite other registers. #if 0 unused include of opcode/mips.h.
