107 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
109 * sim-endian.h: Don't have parameters on macro definitions which
110 are simply renaming functions, to permit use of XCONCAT2 in both
111 the macro name and the arguments in a use of such a definition.
113 2000-11-15 Jim Blandy <jimb@redhat.com>
115 * sim_calls.c: Doc fix.
116 (sim_fetch_register, sim_store_register): Call

151 1999-05-08 Felix Lee <flee@cygnus.com>
153 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
154 * configure: Regenerated to track ../common/aclocal.m4 changes.
156 1999-04-02 Keith Seitz <keiths@cygnus.com>

162 after the specified POLL_QUIT_INTERVAL.
164 1999-02-22 Jim Lemke <jlemke@cygnus.com>
166 * dc-complex: Force expansion on all bits of field BO.

174 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
176 Make the simulator compatible with the MPC750. It would be nicer
177 to make this a real multi-sim, but that's more work than we have
179 * emul_generic.c (emul_add_tree_options): Only require strict
180 alignment if it was explicitly requested at configuration time.
181 Don't make it the default for little-endian machines.
182 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
183 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
184 THRM2, THRM3): Plop in the MPC750 SPR registers.
185 (DABR): This is weird. This was HID5, but the PPC spec says this
186 should be DABR; why did some random processor use it for something
187 else? The HID5 entry dates back to the original checkin of the
188 simulator code in 1995, so remove it.
189 * sim_calls.c (register_names): Delete this; since the user can
190 now change GDB's list of register names dynamically, we can't
191 pretend there's a static mapping here.
192 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
193 function to get the register name. That ought to be accurate.
194 However, we're changing a compile-time dependency (using the
195 REGISTER_NAMES macro) into a link- and run-time dependency
196 (calling REGISTER_NAME, which happens to be a function call on the
199 1999-01-22 Jim Lemke <jlemke@cygnus.com>

221 poll the external environment.
223 1998-11-19 Michael Meissner <meissner@cygnus.com>
225 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
226 fractional type, so that quiet NaN's aren't treated like
229 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
231 * table.c (table_open): For cygwin hosts, we need to use the
232 return value from the read routine as the number of bytes to
233 process. This apparently is due to text-mode vs binary-mode. If
234 the mounts are done text-mode, then the size returnedby fstat()
235 may be different than the number of bytes "read" in text mode.
237 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
239 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

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

672 determine the simulation speed by looking at the number of elapsed
673 ticks recorded by the event queue.
675 * psim.c (psim_write_register, psim_read_register): Force the cpu
676 to zero when it is either of `-1' or `nr_cpus'. In both cases the
677 next cpu would be zero any way.
679 * mon.c (mon_print_info): If possible, print the system cycle
680 performance. This is an indication of the number of instructions
683 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
685 * The code to allow an event queue to be updated during a signal
686 was missing. For main.c, a cntrl-c simulation termination wasn't

747 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
749 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
750 debug.c. It could be much simpler.
752 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

809 * The code that put values in and extracted values from the cache
810 was too compilicated. The cache table did not allow values to be
811 computed from cache entries. #defines could only be used when a
812 cache was present, remove the restriction.
814 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
815 scratch variable is defined when a cache entry is beinf
816 filled. Change the definition of a COMPUTE variable to be defined
817 when the cache entry is being used.
818 * gen-icache.c: Update.
820 * ld-cache.h, ld-cache.c: Change field names so that their meaning

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

3211 according to the verbosity. In turn output device and trace
3214 * main.c (main): Update to use new system
3215 * sim_calls.c (sim_open, sim_do_command): Ditto
3217 * psim.c (psim_options): Add `r' option - ram size.
3218 * psim.c (psim_options): Add `o' option - openboot tree entry.
3219 * psim.c (psim_options): Add `h'/`H' options - more help.
3221 * debug.c (trace_usage): Add more detailed help.
3222 * device.c (device_usage): New. Output help including a list of
3223 the devices currently available in the device table.
3224 * device_table.c: Add usage operator to each device.
3226 * corefile.c (core_create, core_device_create): Adjust so that the
3227 core device is created earlier for psim_tree(). Core can later be
3230 * psim.c (psim_create): Update to handle above way of creating
3231 things. Extract all information from the device tree.
3233 * device_tree.c (trace_*): New device node, its properties are
3234 used to set the value of the trace options. Init this device (in
3235 psim_options) when ever the options are updated.
3237 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
3239 * debug.h: Add trace_print_info, trace_print_device_tree and
3240 trace_dump_device_tree. The first is a replacement for the
3241 variable `print_info' found in main.c and sim_calls.c. The latter
3242 two enable the dumping of the entire device tree.
3244 * debug.c: Add to trace_description table.
3246 * main.c (main): Use above trace instead of local variable
3247 * sim_calls.c (sim_close): Ditto
3249 * device.c (device_tree_print_device): New. Prints the device
3250 tree in a format that is consistent with what can be parsed by the
3251 device tree load from file code.
3253 * psim.c (psim_create): Dump device tree if enabled. If nump
3254 selected, exit psim immediatly.
3256 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3258 * corefile-n.h (core_map_read_N): When mapping from an address to
3259 a device, do not subtract the devices base. The device its self
3260 can do this. Brings the behavour into line with OpenBoot.
3261 * corefile-n.h (core_map_write_N): Ditto
3262 * corefile.c (core_map_read_buffer): Ditto
3263 * corefile.c (core_map_write_buffer): Ditto
3265 * device_table.c (console_io_read_buffer_callback): Adjust to
3266 handle biased address.
3267 * device_table.c (console_io_write_buffer_callback): Ditto
3269 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3271 * device.c (attach_device_interrupt_edge): New. Interrupt model
3272 did not allow interrupts to be wired up as a general net (edges).
3273 Re-implement so that interrupt events can be passed to multiple
3274 controllers and interrupt controllers can further propogate
3277 * device.c (attach_device_interrupt_edge) : New, Ditto
3278 * device.c (detach_device_interrupt_edge) : New, Ditto
3279 * device.c (clean_device_interrupt_edges) : New, Ditto
3280 * device.c (device_interrupt_event) : New, Ditto
3281 * device.c (device_interrupt_attach) : New, Ditto
3282 * device.c (device_interrupt_detach) : New, Ditto
3283 * device.c (device_child_interrupt_attach) : New, Ditto
3284 * device.c (device_child_interrupt_detach) : New, Ditto
3286 * device.c (device_attach_interrupt) : Delete old
3287 * device.c (device_detach_interrupt) : Delete old
3288 * device.c (device_interrupt) : Delete old
3289 * device.c (device_interrupt_ack) : Delete old
3291 * device_table.c (unimp_*) : Update to match
3293 * device_table.c (icu_io_write_buffer_callback) : Update to use
3295 * device_table.c (icu_interrupt_event_callback) : Ditto
3297 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3299 * device.c (external_to_device) : New function that provides a
3300 standard mapping between a devices internal representation (a
3301 pointer) and its external (or what is passed to a client)
3302 representation (a phandle). Implement using the cap object
3303 attached to the root node.
3305 * device.c (device_to_external) : Ditto
3306 * device.c (external_to_device_instance) : Ditto but for ihandle
3307 and device instance.
3308 * device.c (device_instance_to_external) : Ditto
3310 * Makefile (device.o): Add dependency on cap.
3312 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3313 needing to translate between internal and external representations
3314 changed to use the external_to_device et.al. device operations.
3315 * emul_chirp.c (chirp_emul_*) : Ditto
3317 * Makefile (emul_chirp.o): Remove dependency on cap
3319 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3321 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3322 on OpenBoot note section.
3324 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3326 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3327 read/write calls for buffer transfers. This will cause a fault to
3328 occure if the transfer fails. CHRP catches the fault while the
3329 others suffer the consequences.
3330 (emul_read_buffer): Ditto.
3331 (emul_write_word): Ditto.
3332 (emul_read_word): Ditto.
3333 (emul_read_string): Ditto.
3335 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3337 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),

3343 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3344 (emul_chirp_create) : Use names instead of numbers for
3345 instructions being stored in memory.
3347 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3349 * Makefile.in (maintainer-clean): Remove .log, core and *.core
