88 ;; we cannot simply test $dccr, because that does not necessarily
89 ;; reflect what mode we'll return into.
111 ;; Since we dont really want to have two epilogues (one for system calls
112 ;; and one for interrupts) we push the contents of BRP instead of IRP in the

119 ;; In r9 we have the wanted syscall number. Arguments come in r10,r11,r12,r13,mof,srp

178 ;; r9 is a parameter - if >=1 we came from a syscall, if 0, from an irq
200 ;; now we have a 4-word SBFS frame which we do not want to restore
