You need to look up a header file, true. But these macros are worth
doing so.

as can be seen from macro definitions, they specify some more
information ecplicitly; alignment, type of symbols, stack frame info
which helps generating debug info.

These macros or their variants have been used in SGI or Algorithmics
early MIPS programming, PMON, YAMON and of course Linux. They are good
helper for MIPS assemblers, so I hope get them in.
