This microcontroller contains two "cores", for each of the cores is 
different compiler. After everything is compiled all is linked to one fiele. 
The xgate compiler
compiles interrupt service routines for xgate core.

what about ABI determination in this case. Is it supported on Generic 
systems?


Thx
