** Back end tables for z8000 **
** Author: Jan Voors **
** **
** wordsize = 2 bytes, pointersize = 2 bytes. **
** **
** Register R13 is used as LB, RR14 is the normal **
** z8000-stackpointer. Some global variables are used: **
** - reghp : the heap pointer **
** - trpim : trap ignore mask **
** - trppc : address of user defined trap handler **
** **
** Floating point arithmetic and constants are not **
** implemented. **
