93 * sim-endian.h: Don't have parameters on macro definitions which
94 are simply renaming functions, to permit use of XCONCAT2 in both
95 the macro name and the arguments in a use of such a definition.
97 2000-11-15 Jim Blandy <jimb@redhat.com>
99 * sim_calls.c: Doc fix.
100 (sim_fetch_register, sim_store_register): Call

135 1999-05-08 Felix Lee <flee@cygnus.com>
137 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
138 * configure: Regenerated to track ../common/aclocal.m4 changes.
140 1999-04-02 Keith Seitz <keiths@cygnus.com>

146 after the specified POLL_QUIT_INTERVAL.
148 1999-02-22 Jim Lemke <jlemke@cygnus.com>
150 * dc-complex: Force expansion on all bits of field BO.

158 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
160 Make the simulator compatible with the MPC750. It would be nicer
161 to make this a real multi-sim, but that's more work than we have
163 * emul_generic.c (emul_add_tree_options): Only require strict
164 alignment if it was explicitly requested at configuration time.
165 Don't make it the default for little-endian machines.
166 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
167 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
168 THRM2, THRM3): Plop in the MPC750 SPR registers.
169 (DABR): This is weird. This was HID5, but the PPC spec says this
170 should be DABR; why did some random processor use it for something
171 else? The HID5 entry dates back to the original checkin of the
172 simulator code in 1995, so remove it.
173 * sim_calls.c (register_names): Delete this; since the user can
174 now change GDB's list of register names dynamically, we can't
175 pretend there's a static mapping here.
176 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
177 function to get the register name. That ought to be accurate.
178 However, we're changing a compile-time dependency (using the
179 REGISTER_NAMES macro) into a link- and run-time dependency
180 (calling REGISTER_NAME, which happens to be a function call on the
183 1999-01-22 Jim Lemke <jlemke@cygnus.com>

210 fractional type, so that quiet NaN's aren't treated like
213 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
215 * table.c (table_open): For cygwin hosts, we need to use the
216 return value from the read routine as the number of bytes to
217 process. This apparently is due to text-mode vs binary-mode. If
218 the mounts are done text-mode, then the size returnedby fstat()
219 may be different than the number of bytes "read" in text mode.
221 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
223 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

235 return zero when nothing to do.
237 1998-06-26 Michael Meissner <meissner@cygnus.com>
239 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
240 * configure: Regenerate.
241 * emul_{netbsd,unix}.c (toplevel): No longer try to include
242 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
244 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
246 * Makefile.in: The run target depended on a target psim$(EXEEXT),
247 but there was no such target, only plain psim. So I changed the
248 run target to depend on psim.
250 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
252 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
253 now defined in ../common/aclocal.m4, and the double definition causes
254 problems with AC_SUBST of EXEEXT.

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

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

793 * The code that put values in and extracted values from the cache
794 was too compilicated. The cache table did not allow values to be
795 computed from cache entries. #defines could only be used when a
796 cache was present, remove the restriction.
798 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
799 scratch variable is defined when a cache entry is beinf
800 filled. Change the definition of a COMPUTE variable to be defined
801 when the cache entry is being used.
802 * gen-icache.c: Update.
804 * ld-cache.h, ld-cache.c: Change field names so that their meaning

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

3210 * corefile.c (core_create, core_device_create): Adjust so that the
3211 core device is created earlier for psim_tree(). Core can later be
3214 * psim.c (psim_create): Update to handle above way of creating
3215 things. Extract all information from the device tree.
3217 * device_tree.c (trace_*): New device node, its properties are
3218 used to set the value of the trace options. Init this device (in
3219 psim_options) when ever the options are updated.
3221 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
3223 * debug.h: Add trace_print_info, trace_print_device_tree and
3224 trace_dump_device_tree. The first is a replacement for the
3225 variable `print_info' found in main.c and sim_calls.c. The latter
3226 two enable the dumping of the entire device tree.
3228 * debug.c: Add to trace_description table.
3230 * main.c (main): Use above trace instead of local variable
3231 * sim_calls.c (sim_close): Ditto
3233 * device.c (device_tree_print_device): New. Prints the device
3234 tree in a format that is consistent with what can be parsed by the
3235 device tree load from file code.
3237 * psim.c (psim_create): Dump device tree if enabled. If nump
3238 selected, exit psim immediatly.
3240 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3242 * corefile-n.h (core_map_read_N): When mapping from an address to
3243 a device, do not subtract the devices base. The device its self
3244 can do this. Brings the behavour into line with OpenBoot.
3245 * corefile-n.h (core_map_write_N): Ditto
3246 * corefile.c (core_map_read_buffer): Ditto
3247 * corefile.c (core_map_write_buffer): Ditto
3249 * device_table.c (console_io_read_buffer_callback): Adjust to
3250 handle biased address.
3251 * device_table.c (console_io_write_buffer_callback): Ditto
3253 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3255 * device.c (attach_device_interrupt_edge): New. Interrupt model
3256 did not allow interrupts to be wired up as a general net (edges).
3257 Re-implement so that interrupt events can be passed to multiple
3258 controllers and interrupt controllers can further propogate
3261 * device.c (attach_device_interrupt_edge) : New, Ditto
3262 * device.c (detach_device_interrupt_edge) : New, Ditto
3263 * device.c (clean_device_interrupt_edges) : New, Ditto
3264 * device.c (device_interrupt_event) : New, Ditto
3265 * device.c (device_interrupt_attach) : New, Ditto
3266 * device.c (device_interrupt_detach) : New, Ditto
3267 * device.c (device_child_interrupt_attach) : New, Ditto
3268 * device.c (device_child_interrupt_detach) : New, Ditto
3270 * device.c (device_attach_interrupt) : Delete old
3271 * device.c (device_detach_interrupt) : Delete old
3272 * device.c (device_interrupt) : Delete old
3273 * device.c (device_interrupt_ack) : Delete old
3275 * device_table.c (unimp_*) : Update to match
3277 * device_table.c (icu_io_write_buffer_callback) : Update to use
3279 * device_table.c (icu_interrupt_event_callback) : Ditto
3281 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3283 * device.c (external_to_device) : New function that provides a
3284 standard mapping between a devices internal representation (a
3285 pointer) and its external (or what is passed to a client)
3286 representation (a phandle). Implement using the cap object
3287 attached to the root node.
3289 * device.c (device_to_external) : Ditto
3290 * device.c (external_to_device_instance) : Ditto but for ihandle
3291 and device instance.
3292 * device.c (device_instance_to_external) : Ditto
3294 * Makefile (device.o): Add dependency on cap.
3296 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3297 needing to translate between internal and external representations
3298 changed to use the external_to_device et.al. device operations.
3299 * emul_chirp.c (chirp_emul_*) : Ditto
3301 * Makefile (emul_chirp.o): Remove dependency on cap
3303 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3305 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3306 on OpenBoot note section.
3308 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3310 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3311 read/write calls for buffer transfers. This will cause a fault to
3312 occure if the transfer fails. CHRP catches the fault while the
3313 others suffer the consequences.
3314 (emul_read_buffer): Ditto.
3315 (emul_write_word): Ditto.
3316 (emul_read_word): Ditto.
3317 (emul_read_string): Ditto.
3319 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3321 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3322 emul_generic (emul_blr_instruction): Use a real blr instruction to
3323 return from a client service call.
3325 * emul_chirp.c (services): Add all OpenBoot services to table.
3327 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3328 (emul_chirp_create) : Use names instead of numbers for
3329 instructions being stored in memory.
3331 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3333 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3334 (From NetBSD) files.
