202 * When performance monitoring is disabled, it is still possible to
203 determine the simulation speed by looking at the number of elapsed
204 ticks recorded by the event queue.
206 * psim.c (psim_write_register, psim_read_register): Force the cpu
207 to zero when it is either of `-1' or `nr_cpus'. In both cases the
208 next cpu would be zero any way.
210 * mon.c (mon_print_info): If possible, print the system cycle
211 performance. This is an indication of the number of instructions
214 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
216 * The code to allow an event queue to be updated during a signal
217 was missing. For main.c, a cntrl-c simulation termination wasn't

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

319 that the compiler gets a better chance of eliminating dead
322 * gen-icache.c (print_icache_extraction): For a cache entry of
323 the form <name>_is_<const> where it is a boolean field, generate
324 the result of the expression instead of the expression its self.

340 * The code that put values in and extracted values from the cache
341 was too compilicated. The cache table did not allow values to be
342 computed from cache entries. #defines could only be used when a
343 cache was present, remove the restriction.
345 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
346 scratch variable is defined when a cache entry is beinf
347 filled. Change the definition of a COMPUTE variable to be defined
348 when the cache entry is being used.
349 * gen-icache.c: Update.
351 * ld-cache.h, ld-cache.c: Change field names so that their meaning
352 is more obvious. old_name->field_name, new_name->derived_name.

364 * igen.c (main): Change 'R' option so that it does not force the
367 * configure.in (enable-sim-icache): Clarify description. Make
368 #define one of the defaults regardless of the cache. Probably
369 should revamp and add a separate option.

2716 devices to the device tree so that a single printf style function
2719 * device.c (device_tree_add_*): Delete. Replaced by above.
2721 * device.c (split_device_specifier): Functions to manipulate a
2722 device specifier (path) breaking it into its components
2723 * device.c (split_property_specifier): Ditto
2724 * device.c (split_device_name): Ditto
2725 * device.c (split_find_device): Ditto
2727 * device.c (scan_*): Delete

2732 Wed Jan 17 19:51:56 1996 Andrew Cagney <cagney@highland.com.au>
2734 * psim.c(psim_options): Parse the psim options, installing their
2735 value in the device tree. Options are now first entered into a
2736 device tree and then extracted out again when needed. This allows
2737 greater flexability in configuration.
2739 * psim.c (psim_tree): Returns a basic device tree ready for
2740 parsing by psim_options.
2741 * psim.c (psim_usage): New. Give usage to varing levels of detail
2742 according to the verbosity. In turn output device and trace
2745 * main.c (main): Update to use new system
2746 * sim_calls.c (sim_open, sim_do_command): Ditto
2748 * psim.c (psim_options): Add `r' option - ram size.

2754 the devices currently available in the device table.
2755 * device_table.c: Add usage operator to each device.
2757 * corefile.c (core_create, core_device_create): Adjust so that the
2758 core device is created earlier for psim_tree(). Core can later be
2761 * psim.c (psim_create): Update to handle above way of creating
2762 things. Extract all information from the device tree.
2764 * device_tree.c (trace_*): New device node, its properties are
2765 used to set the value of the trace options. Init this device (in
2766 psim_options) when ever the options are updated.
2768 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
2770 * debug.h: Add trace_print_info, trace_print_device_tree and
2771 trace_dump_device_tree. The first is a replacement for the
2772 variable `print_info' found in main.c and sim_calls.c. The latter
2773 two enable the dumping of the entire device tree.
2775 * debug.c: Add to trace_description table.
2777 * main.c (main): Use above trace instead of local variable
2778 * sim_calls.c (sim_close): Ditto
2780 * device.c (device_tree_print_device): New. Prints the device
2781 tree in a format that is consistent with what can be parsed by the
2782 device tree load from file code.
2784 * psim.c (psim_create): Dump device tree if enabled. If nump
2785 selected, exit psim immediatly.
2787 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
2789 * corefile-n.h (core_map_read_N): When mapping from an address to
2790 a device, do not subtract the devices base. The device its self
2791 can do this. Brings the behavour into line with OpenBoot.
2792 * corefile-n.h (core_map_write_N): Ditto
2793 * corefile.c (core_map_read_buffer): Ditto
2794 * corefile.c (core_map_write_buffer): Ditto
2796 * device_table.c (console_io_read_buffer_callback): Adjust to
2797 handle biased address.
2798 * device_table.c (console_io_write_buffer_callback): Ditto
2800 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
2802 * device.c (attach_device_interrupt_edge): New. Interrupt model
2803 did not allow interrupts to be wired up as a general net (edges).
2804 Re-implement so that interrupt events can be passed to multiple
2805 controllers and interrupt controllers can further propogate
2808 * device.c (attach_device_interrupt_edge) : New, Ditto

2828 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
2830 * device.c (external_to_device) : New function that provides a
2831 standard mapping between a devices internal representation (a
2832 pointer) and its external (or what is passed to a client)
2833 representation (a phandle). Implement using the cap object
2834 attached to the root node.
2836 * device.c (device_to_external) : Ditto
2837 * device.c (external_to_device_instance) : Ditto but for ihandle
2838 and device instance.

2841 * Makefile (device.o): Add dependency on cap.
2843 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
2844 needing to translate between internal and external representations
2845 changed to use the external_to_device et.al. device operations.
2846 * emul_chirp.c (chirp_emul_*) : Ditto

2853 on OpenBoot note section.
2855 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
2857 * emul_generic.c (emul_write_buffer): Use vm faulting byte
2858 read/write calls for buffer transfers. This will cause a fault to
2859 occure if the transfer fails. CHRP catches the fault while the
2860 others suffer the consequences.
2861 (emul_read_buffer): Ditto.
2862 (emul_write_word): Ditto.
2863 (emul_read_word): Ditto.
