* traps.s -- define trap linkages for C routines
* -------    -----------------------------------
* Version 8 -- 1987-06-08 -- D.N. Lynx Crowe
*
* Caution:  these are serially re-useable, but NOT reentrant, so
* don't use them in interrupt processing code.
*
* An exception is made for ROMP in _trap15 for breakpoints so that the
* debug code can be debugged.
