 140
 141         * cpu.c (cpu_create): Use psim_event_queue to obtain the event
 142         queue instead of it being passed in.  No longer allow access to

 144
 145 Sun Mar 17 22:40:57 1996  Andrew Cagney  <cagney@highland.com.au>
 146
 147         * events.h, events.c (event_handler): Remove event_queue from
 148         arguments passed to an event handler.  That argument is redundant

 179         checks for the posibility that a recent change to the MSR may have

 181         masked be the EE bit.
 182
 183         * ppc-instructions (mtmsr, mfmsr, rfi): Check for posibility of

 191         pending decrementer and external interrupts.
 192

 196         between the interrupt controller and the simulators internal
 197         processor model.  Maps device interrupts onto the processor
 198         interrupt function calls.
