Augment each extracted field with a comment citing the codes

works for normal and boolean table entries.

* gen-idecode.c: Re-work the table lookup code so that it assumes
|

that the entry is a leaf by default. Simplify the boolean table
|

entry code so that it involves a mask + test instead of shift +
|

|

* When performance monitoring is disabled, it is still possible to
|
||||
determine the simulation speed by looking at the number of elapsed
|
||||
ticks recorded by the event queue.
|
||||
|
||||
* psim.c (psim_write_register, psim_read_register): Force the cpu
|

to zero when it is either of `-1' or `nr_cpus'. In both cases the
|
||||
next cpu would be zero any way.
|

* mon.c (mon_print_info): If possible, print the system cycle

|

|

* The code to allow an event queue to be updated during a signal
|
||||
was missing. For main.c, a cntrl-c simulation termination wasn't
|
||||
handled cleanly.
|
||||
|
||||
* The simulation would not correctly restart if an event requested
|
||||
that the simulation be halted.
|
||||
|

* psim.c (psim_options): Add hack to -i option to optionally
|
||||
include a level vis -i2.
|
||||
(psim_usage): Document.
|
||||
|
||||
* main.c (cntrl_c, cntrl_c_simulation): New functions. When a
|
||||
cntrl-c occures schedule an event to halt the simulation.
|
||||
(main): Catch CNTRL-C signals with the function cntrl_c.
|
||||
|
||||
* events.c (event_queue_process): Mask interrupts while
|
||||
manipulating the async event queue.
|
||||
(event_queue_init): Ditto.
|
||||
(event_queue_schedule_after_signal): Ditto.
|
||||
|
||||
* events.c (event_queue_process): Mark the event queue as being in
|
||||
the processing state when processing has started. Adjust code
|
||||
so that it is tolerant of halts.
|
||||
(event_queue_init): Start the event queue out with processing
|
||||
false.
|
||||
(event_queue_tick): Check that processing isn't still being
|
||||
performed.
|
||||
|
||||
* gen-idecode.c (print_run_until_stop_body): Call
|
||||
event_queue_process_events to clear possibly pending events before
|
||||
starting a simulation run. Re-arange main loop so that simulator
|
||||
is correctly restarted when an event halts the simulation.
|
||||
|
||||
* psim.c (psim_halt): Handle an event halting the simulation.
|
||||
* psim.c (psim_init): Adjust initial cpu - == -1 - to match
|
||||
reworked idecode.

|
||||
* ppc-opcode-complex: Correct typo - was expanding ORA instead of
|
||||
RA. Based on instruction frequency stats, expand additional
|
||||
instructions.
|
||||
* ppc-instructions: Change all `RA == 0' to RA_is_0.
|
||||
|
||||
* ppc-opcode-stupid: Move all but the basic table in -complex into
|
||||
here. Update to new format.
|
||||
|
||||
* Makefile.in (tmp-defines): New target. Force defines.h to always
|
||||
be built. Hence get ppc-opcode-goto to build.
