125 Wed Feb 5 10:56:27 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
127 * Property create/initialization still wasn't correctly ordered.
128 Should be delaying everything related to ihandle creation until
129 after the rest of the tree has been established.
131 * device.c (device_find_ihandle_runtime_property): Update.
132 (device_add_ihandle_runtime_property): Update.

173 or doubles clock interrupts.
176 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

208 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
210 * When performance monitoring is disabled, it is still possible to
211 determine the simulation speed by looking at the number of elapsed
212 ticks recorded by the event queue.
214 * psim.c (psim_write_register, psim_read_register): Force the cpu
215 to zero when it is either of `-1' or `nr_cpus'. In both cases the
216 next cpu would be zero any way.
218 * mon.c (mon_print_info): If possible, print the system cycle
219 performance. This is an indication of the number of instructions
222 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
224 * The code to allow an event queue to be updated during a signal
225 was missing. For main.c, a cntrl-c simulation termination wasn't
228 * The simulation would not correctly restart if an event requested
229 that the simulation be halted.
231 * psim.c (psim_options): Add hack to -i option to optionally
232 include a level vis -i2.
233 (psim_usage): Document.

247 (event_queue_init): Start the event queue out with processing
249 (event_queue_tick): Check that processing isn't still being
252 * gen-idecode.c (print_run_until_stop_body): Call
253 event_queue_process_events to clear possibly pending events before

269 here. Update to new format.

281 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
282 to be initialized independant of the rest of the simulation
283 initalization. Otherwize a trace option explictly set from gdb
284 could be overridden by hw_trace.
286 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
288 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
289 debug.c. It could be much simpler.
291 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
293 * Some devices support removable media. Add hooks to the disk

307 string array - use the first entry for the initial file image.
309 * tree.c (print_string_aray_property): New function - print a

326 as RA_is_0. If possible generate the result of the expression so
327 that the compiler gets a better chance of eliminating dead
330 * gen-icache.c (print_icache_extraction): For a cache entry of
331 the form <name>_is_<const> where it is a boolean field, generate
332 the result of the expression instead of the expression its self.
333 (print_icache_body): Remove code that was looking for *_is_0 and
334 then generating corresponding definitions.
336 * gen-icache.c (print_icache_struct): If there is no cache, do not

346 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
348 * The code that put values in and extracted values from the cache
349 was too compilicated. The cache table did not allow values to be
350 computed from cache entries. #defines could only be used when a
351 cache was present, remove the restriction.
353 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
354 scratch variable is defined when a cache entry is beinf
355 filled. Change the definition of a COMPUTE variable to be defined
356 when the cache entry is being used.
357 * gen-icache.c: Update.
359 * ld-cache.h, ld-cache.c: Change field names so that their meaning
360 is more obvious. old_name->field_name, new_name->derived_name.
361 * gen-icache.c: Update
363 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
364 different types of cache code - put into cache, extract from
365 cache, no cache - an explicit argument to print_icache_body.
366 * gen-icache.c (print_icache_extraction): Ditto.
368 * gen-semantics.c (print_c_semantic): Update use.
369 * gen-idecode.c (print_jump_insn): Update use.
370 * gen-icache.c (print_icache_function): Update use.
372 * igen.c (main): Change 'R' option so that it does not force the
375 * configure.in (enable-sim-icache): Clarify description. Make
376 #define one of the defaults regardless of the cache. Probably
377 should revamp and add a separate option.

381 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1656 * std-config.h (SEMANTICS_INLINE): By default, mask out the
1657 inlining of semantic functions from DEFAULT_INLINE. Almost all

1689 always update the cache_entries semantic and address fields.
1691 * gen-idecode.c (print_idecode_switch_illegal): Include a break
1692 when generating illegal instructions. This was commented out
1693 which is a hangover from looking a at switch statements generated

1745 option directly into the device tree. Was using atol() which is
1746 dangerously non portable.
1748 Mon Jul 22 22:17:08 1996 Andrew Cagney <cagney@highland.com.au>
1750 * configure.in (icache): Extend icache flag to include an insn

1789 * psim.c (run_until_stop): Delete the old run_until_stop function

1848 * igen.c: Add option (-C) to generate semantics in the instruction
1851 * configure.in (--enable-sim-icache): Accept an option list such
1852 as 1024,define. Add a new choice to the list - semantic - which

1858 * configure.in: New option --enable-sim-line-nr (default enabled).

1914 * configure.in: Adjust filter flag so that default includes 32bit

2742 * psim.c(psim_options): Parse the psim options, installing their
2743 value in the device tree. Options are now first entered into a
2744 device tree and then extracted out again when needed. This allows
2745 greater flexability in configuration.

2748 parsing by psim_options.
2749 * psim.c (psim_usage): New. Give usage to varing levels of detail

2770 things. Extract all information from the device tree.
2772 * device_tree.c (trace_*): New device node, its properties are
2773 used to set the value of the trace options. Init this device (in
2774 psim_options) when ever the options are updated.

2778 * debug.h: Add trace_print_info, trace_print_device_tree and
2779 trace_dump_device_tree. The first is a replacement for the
2780 variable `print_info' found in main.c and sim_calls.c. The latter
2781 two enable the dumping of the entire device tree.
2783 * debug.c: Add to trace_description table.

2786 * sim_calls.c (sim_close): Ditto

2793 selected, exit psim immediatly.

2797 * corefile-n.h (core_map_read_N): When mapping from an address to
2798 a device, do not subtract the devices base. The device its self
2799 can do this. Brings the behavour into line with OpenBoot.
2800 * corefile-n.h (core_map_write_N): Ditto
2801 * corefile.c (core_map_read_buffer): Ditto
2802 * corefile.c (core_map_write_buffer): Ditto
2804 * device_table.c (console_io_read_buffer_callback): Adjust to
2805 handle biased address.
2806 * device_table.c (console_io_write_buffer_callback): Ditto
2808 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
2810 * device.c (attach_device_interrupt_edge): New. Interrupt model
2811 did not allow interrupts to be wired up as a general net (edges).
2812 Re-implement so that interrupt events can be passed to multiple
2813 controllers and interrupt controllers can further propogate
2816 * device.c (attach_device_interrupt_edge) : New, Ditto

2836 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
2838 * device.c (external_to_device) : New function that provides a
2839 standard mapping between a devices internal representation (a
2840 pointer) and its external (or what is passed to a client)
2841 representation (a phandle). Implement using the cap object
2842 attached to the root node.
2844 * device.c (device_to_external) : Ditto
2845 * device.c (external_to_device_instance) : Ditto but for ihandle
2846 and device instance.

2852 needing to translate between internal and external representations
2853 changed to use the external_to_device et.al. device operations.

2865 * emul_generic.c (emul_write_buffer): Use vm faulting byte
2866 read/write calls for buffer transfers. This will cause a fault to
2867 occure if the transfer fails. CHRP catches the fault while the
2868 others suffer the consequences.
2869 (emul_read_buffer): Ditto.
2870 (emul_write_word): Ditto.
2871 (emul_read_word): Ditto.
