185 * When performance monitoring is disabled, it is still possible to
186 determine the simulation speed by looking at the number of elapsed
187 ticks recorded by the event queue.
189 * psim.c (psim_write_register, psim_read_register): Force the cpu
190 to zero when it is either of `-1' or `nr_cpus'. In both cases the
191 next cpu would be zero any way.
193 * mon.c (mon_print_info): If possible, print the system cycle
194 performance. This is an indication of the number of instructions
197 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
199 * The code to allow an event queue to be updated during a signal
200 was missing. For main.c, a cntrl-c simulation termination wasn't
203 * The simulation would not correctly restart if an event requested
204 that the simulation be halted.

256 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
257 to be initialized independant of the rest of the simulation
258 initalization. Otherwize a trace option explictly set from gdb
259 could be overridden by hw_trace.
261 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
263 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
264 debug.c. It could be much simpler.
266 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

323 * The code that put values in and extracted values from the cache
324 was too compilicated. The cache table did not allow values to be
325 computed from cache entries. #defines could only be used when a
326 cache was present, remove the restriction.
328 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
329 scratch variable is defined when a cache entry is beinf
330 filled. Change the definition of a COMPUTE variable to be defined
331 when the cache entry is being used.
332 * gen-icache.c: Update.
334 * ld-cache.h, ld-cache.c: Change field names so that their meaning

350 * configure.in (enable-sim-icache): Clarify description. Make
351 #define one of the defaults regardless of the cache. Probably
352 should revamp and add a separate option.

2717 * psim.c(psim_options): Parse the psim options, installing their
2718 value in the device tree. Options are now first entered into a
2719 device tree and then extracted out again when needed. This allows
2720 greater flexability in configuration.
2722 * psim.c (psim_tree): Returns a basic device tree ready for
2723 parsing by psim_options.
2724 * psim.c (psim_usage): New. Give usage to varing levels of detail
2725 according to the verbosity. In turn output device and trace
2728 * main.c (main): Update to use new system
2729 * sim_calls.c (sim_open, sim_do_command): Ditto
2731 * psim.c (psim_options): Add `r' option - ram size.
2732 * psim.c (psim_options): Add `o' option - openboot tree entry.
2733 * psim.c (psim_options): Add `h'/`H' options - more help.
2735 * debug.c (trace_usage): Add more detailed help.
2736 * device.c (device_usage): New. Output help including a list of
2737 the devices currently available in the device table.
2738 * device_table.c: Add usage operator to each device.
2740 * corefile.c (core_create, core_device_create): Adjust so that the
2741 core device is created earlier for psim_tree(). Core can later be
2744 * psim.c (psim_create): Update to handle above way of creating
2745 things. Extract all information from the device tree.
2747 * device_tree.c (trace_*): New device node, its properties are
2748 used to set the value of the trace options. Init this device (in
2749 psim_options) when ever the options are updated.
2751 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
2753 * debug.h: Add trace_print_info, trace_print_device_tree and
2754 trace_dump_device_tree. The first is a replacement for the
2755 variable `print_info' found in main.c and sim_calls.c. The latter
2756 two enable the dumping of the entire device tree.
2758 * debug.c: Add to trace_description table.
2760 * main.c (main): Use above trace instead of local variable
2761 * sim_calls.c (sim_close): Ditto
2763 * device.c (device_tree_print_device): New. Prints the device
2764 tree in a format that is consistent with what can be parsed by the
2765 device tree load from file code.
2767 * psim.c (psim_create): Dump device tree if enabled. If nump
2768 selected, exit psim immediatly.
2770 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
2772 * corefile-n.h (core_map_read_N): When mapping from an address to
2773 a device, do not subtract the devices base. The device its self
2774 can do this. Brings the behavour into line with OpenBoot.
2775 * corefile-n.h (core_map_write_N): Ditto
2776 * corefile.c (core_map_read_buffer): Ditto
2777 * corefile.c (core_map_write_buffer): Ditto
2779 * device_table.c (console_io_read_buffer_callback): Adjust to
2780 handle biased address.
2781 * device_table.c (console_io_write_buffer_callback): Ditto
2783 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
2785 * device.c (attach_device_interrupt_edge): New. Interrupt model
2786 did not allow interrupts to be wired up as a general net (edges).
2787 Re-implement so that interrupt events can be passed to multiple
2788 controllers and interrupt controllers can further propogate
2791 * device.c (attach_device_interrupt_edge) : New, Ditto
2792 * device.c (detach_device_interrupt_edge) : New, Ditto
2793 * device.c (clean_device_interrupt_edges) : New, Ditto
2794 * device.c (device_interrupt_event) : New, Ditto
2795 * device.c (device_interrupt_attach) : New, Ditto
2796 * device.c (device_interrupt_detach) : New, Ditto
2797 * device.c (device_child_interrupt_attach) : New, Ditto
2798 * device.c (device_child_interrupt_detach) : New, Ditto
2800 * device.c (device_attach_interrupt) : Delete old
2801 * device.c (device_detach_interrupt) : Delete old
2802 * device.c (device_interrupt) : Delete old
2803 * device.c (device_interrupt_ack) : Delete old
2805 * device_table.c (unimp_*) : Update to match
2807 * device_table.c (icu_io_write_buffer_callback) : Update to use
2809 * device_table.c (icu_interrupt_event_callback) : Ditto
2811 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
2813 * device.c (external_to_device) : New function that provides a
2814 standard mapping between a devices internal representation (a
2815 pointer) and its external (or what is passed to a client)
2816 representation (a phandle). Implement using the cap object
2817 attached to the root node.
2819 * device.c (device_to_external) : Ditto
2820 * device.c (external_to_device_instance) : Ditto but for ihandle
2821 and device instance.
2822 * device.c (device_instance_to_external) : Ditto
2824 * Makefile (device.o): Add dependency on cap.
2826 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
2827 needing to translate between internal and external representations
2828 changed to use the external_to_device et.al. device operations.
2829 * emul_chirp.c (chirp_emul_*) : Ditto
2831 * Makefile (emul_chirp.o): Remove dependency on cap
2833 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
2835 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
2836 on OpenBoot note section.
2838 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
2840 * emul_generic.c (emul_write_buffer): Use vm faulting byte
2841 read/write calls for buffer transfers. This will cause a fault to
2842 occure if the transfer fails. CHRP catches the fault while the
2843 others suffer the consequences.
2844 (emul_read_buffer): Ditto.
2845 (emul_write_word): Ditto.
2846 (emul_read_word): Ditto.
2847 (emul_read_string): Ditto.
2849 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
2851 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
