 118
 119         * cpu.c (cpu_create): Use psim_event_queue to obtain the event
 120         queue instead of it being passed in.  No longer allow access to
 121         the cpu's copy of the event queue.
 122
 123 Sun Mar 17 22:40:57 1996  Andrew Cagney  <cagney@highland.com.au>
 124
 125         * events.h, events.c (event_handler): Remove event_queue from
 126         arguments passed to an event handler.  That argument is redundant

 146
 147         * hw_cpu.c, hw_nvram.c, hw_memory.c, hw_eeprom.c, device_table.c:

 154         tried again later.
 155
 156         * interrupts.c (check_masked_interrupt): New function.  (re)
 157         checks for the posibility that a recent change to the MSR may have

 159         masked be the EE bit.
 160
 161         * ppc-instructions (mtmsr, mfmsr, rfi): Check for posibility of

 165         leaving it to that module to handle both interrupt synchronization
 166         and masking.

 169         pending decrementer and external interrupts.
 170
 171 Sun Mar 17 22:40:57 1996  Andrew Cagney  <cagney@highland.com.au>
 172
 173         * hw_cpu.c, hw_cpu.h: New files.  Implement a device that sits
 174         between the interrupt controller and the simulators internal
 175         processor model.  Maps device interrupts onto the processor
 176         interrupt function calls.

 199         * device.c (device_tree_add_parsed): Use the interrupt conversion
 200         functions to determine the interrupt port numbers.
