 118
 119         * psim.h, psim.c (psim_event_queue): New function.  Grant access
 120         to the simulation event queue.  Will make this the single point of

 123
 124         * cpu.c (cpu_create): Use psim_event_queue to obtain the event
 125         queue instead of it being passed in.  No longer allow access to
 126         the cpu's copy of the event queue.
 127
 128 Sun Mar 17 22:40:57 1996  Andrew Cagney  <cagney@highland.com.au>
 129
 130         * events.h, events.c (event_handler): Remove event_queue from
 131         arguments passed to an event handler.  That argument is redundant

 147         * device_table.h: Don't pass `system' into each device when it is
 148         being initialized, this is now available using device_system(me).

 151
 152         * hw_cpu.c, hw_nvram.c, hw_memory.c, hw_eeprom.c, device_table.c:

 159         tried again later.
 160
 161         * interrupts.c (check_masked_interrupt): New function.  (re)
 162         checks for the posibility that a recent change to the MSR may have
 163         made it possible to deliver an interrupt that was previously
 164         masked be the EE bit.
 165
 166         * ppc-instructions (mtmsr, mfmsr, rfi): Check for posibility of

 170         leaving it to that module to handle both interrupt synchronization
 171         and masking.

 174         pending decrementer and external interrupts.
 175
 176 Sun Mar 17 22:40:57 1996  Andrew Cagney  <cagney@highland.com.au>
 177
 178         * hw_cpu.c, hw_cpu.h: New files.  Implement a device that sits
 179         between the interrupt controller and the simulators internal
 180         processor model.  Maps device interrupts onto the processor
 181         interrupt function calls.

 204         * device.c (device_tree_add_parsed): Use the interrupt conversion
 205         functions to determine the interrupt port numbers.
 206
 207         * device_table.h: Add table that maps between an interrupts
