25 Wed Feb 5 10:56:27 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
27 * Property create/initialization still wasn't correctly ordered.
28 Should be delaying everything related to ihandle creation until
29 after the rest of the tree has been established.

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

108 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
110 * When performance monitoring is disabled, it is still possible to
111 determine the simulation speed by looking at the number of elapsed
112 ticks recorded by the event queue.
114 * psim.c (psim_write_register, psim_read_register): Force the cpu
115 to zero when it is either of `-1' or `nr_cpus'. In both cases the
116 next cpu would be zero any way.
118 * mon.c (mon_print_info): If possible, print the system cycle
119 performance. This is an indication of the number of instructions
122 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
124 * The code to allow an event queue to be updated during a signal
125 was missing. For main.c, a cntrl-c simulation termination wasn't
128 * The simulation would not correctly restart if an event requested
129 that the simulation be halted.
131 * psim.c (psim_options): Add hack to -i option to optionally
132 include a level vis -i2.
133 (psim_usage): Document.

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

226 as RA_is_0. If possible generate the result of the expression so
227 that the compiler gets a better chance of eliminating dead
230 * gen-icache.c (print_icache_extraction): For a cache entry of
231 the form <name>_is_<const> where it is a boolean field, generate
232 the result of the expression instead of the expression its self.

246 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
248 * The code that put values in and extracted values from the cache
249 was too compilicated. The cache table did not allow values to be
250 computed from cache entries. #defines could only be used when a
251 cache was present, remove the restriction.
253 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
254 scratch variable is defined when a cache entry is beinf
255 filled. Change the definition of a COMPUTE variable to be defined
256 when the cache entry is being used.
257 * gen-icache.c: Update.
259 * ld-cache.h, ld-cache.c: Change field names so that their meaning

268 * gen-semantics.c (print_c_semantic): Update use.
269 * gen-idecode.c (print_jump_insn): Update use.

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

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

1758 * configure.in: New option --enable-sim-line-nr (default enabled).

2736 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
2738 * device.c (external_to_device) : New function that provides a
2739 standard mapping between a devices internal representation (a
2740 pointer) and its external (or what is passed to a client)
2741 representation (a phandle). Implement using the cap object
2742 attached to the root node.
2744 * device.c (device_to_external) : Ditto
2745 * device.c (external_to_device_instance) : Ditto but for ihandle
2746 and device instance.
2747 * device.c (device_instance_to_external) : Ditto
2749 * Makefile (device.o): Add dependency on cap.
2751 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
2752 needing to translate between internal and external representations
2753 changed to use the external_to_device et.al. device operations.
2754 * emul_chirp.c (chirp_emul_*) : Ditto
2756 * Makefile (emul_chirp.o): Remove dependency on cap
2758 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
2760 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
2761 on OpenBoot note section.
2763 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
2765 * emul_generic.c (emul_write_buffer): Use vm faulting byte
2766 read/write calls for buffer transfers. This will cause a fault to
2767 occure if the transfer fails. CHRP catches the fault while the
2768 others suffer the consequences.
2769 (emul_read_buffer): Ditto.
2770 (emul_write_word): Ditto.
2771 (emul_read_word): Ditto.
2772 (emul_read_string): Ditto.
2774 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
2776 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
2777 emul_generic (emul_blr_instruction): Use a real blr instruction to
2778 return from a client service call.
2780 * emul_chirp.c (services): Add all OpenBoot services to table.
2782 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
2783 (emul_chirp_create) : Use names instead of numbers for
2784 instructions being stored in memory.
2786 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
2788 * Makefile.in (maintainer-clean): Remove .log, core and *.core
