85 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
87 * sim-endian.h: Don't have parameters on macro definitions which
88 are simply renaming functions, to permit use of XCONCAT2 in both
89 the macro name and the arguments in a use of such a definition.
91 2000-11-15 Jim Blandy <jimb@redhat.com>
93 * sim_calls.c: Doc fix.

125 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
127 * configure: Regenerated to track ../common/aclocal.m4 changes.
129 1999-05-08 Felix Lee <flee@cygnus.com>
131 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
132 * configure: Regenerated to track ../common/aclocal.m4 changes.
134 1999-04-02 Keith Seitz <keiths@cygnus.com>

140 after the specified POLL_QUIT_INTERVAL.
142 1999-02-22 Jim Lemke <jlemke@cygnus.com>
144 * dc-complex: Force expansion on all bits of field BO.
145 Previously, the least-significant (prediction) bit was ignored.

152 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
154 Make the simulator compatible with the MPC750. It would be nicer
155 to make this a real multi-sim, but that's more work than we have
157 * emul_generic.c (emul_add_tree_options): Only require strict
158 alignment if it was explicitly requested at configuration time.
159 Don't make it the default for little-endian machines.
160 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
161 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
162 THRM2, THRM3): Plop in the MPC750 SPR registers.
163 (DABR): This is weird. This was HID5, but the PPC spec says this
164 should be DABR; why did some random processor use it for something
165 else? The HID5 entry dates back to the original checkin of the
166 simulator code in 1995, so remove it.
167 * sim_calls.c (register_names): Delete this; since the user can
168 now change GDB's list of register names dynamically, we can't
169 pretend there's a static mapping here.
170 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
171 function to get the register name. That ought to be accurate.
172 However, we're changing a compile-time dependency (using the
173 REGISTER_NAMES macro) into a link- and run-time dependency
174 (calling REGISTER_NAME, which happens to be a function call on the
177 1999-01-22 Jim Lemke <jlemke@cygnus.com>

203 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
204 fractional type, so that quiet NaN's aren't treated like
207 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
209 * table.c (table_open): For cygwin hosts, we need to use the
210 return value from the read routine as the number of bytes to
211 process. This apparently is due to text-mode vs binary-mode. If
212 the mounts are done text-mode, then the size returnedby fstat()
213 may be different than the number of bytes "read" in text mode.
215 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
217 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

228 * sim_calls.c (sim_fetch_register, sim_store_register):
229 return zero when nothing to do.
231 1998-06-26 Michael Meissner <meissner@cygnus.com>
233 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
234 * configure: Regenerate.
235 * emul_{netbsd,unix}.c (toplevel): No longer try to include
236 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
238 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
240 * Makefile.in: The run target depended on a target psim$(EXEEXT),
241 but there was no such target, only plain psim. So I changed the
242 run target to depend on psim.
244 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
246 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
247 now defined in ../common/aclocal.m4, and the double definition causes
248 problems with AC_SUBST of EXEEXT.

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

720 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
721 to be initialized independant of the rest of the simulation

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

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

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

3212 used to set the value of the trace options. Init this device (in
3213 psim_options) when ever the options are updated.
3215 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
3217 * debug.h: Add trace_print_info, trace_print_device_tree and
3218 trace_dump_device_tree. The first is a replacement for the
3219 variable `print_info' found in main.c and sim_calls.c. The latter
3220 two enable the dumping of the entire device tree.
3222 * debug.c: Add to trace_description table.
3224 * main.c (main): Use above trace instead of local variable
3225 * sim_calls.c (sim_close): Ditto
3227 * device.c (device_tree_print_device): New. Prints the device
3228 tree in a format that is consistent with what can be parsed by the
3229 device tree load from file code.
3231 * psim.c (psim_create): Dump device tree if enabled. If nump
3232 selected, exit psim immediatly.
3234 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3236 * corefile-n.h (core_map_read_N): When mapping from an address to
3237 a device, do not subtract the devices base. The device its self
3238 can do this. Brings the behavour into line with OpenBoot.
3239 * corefile-n.h (core_map_write_N): Ditto
3240 * corefile.c (core_map_read_buffer): Ditto
3241 * corefile.c (core_map_write_buffer): Ditto
3243 * device_table.c (console_io_read_buffer_callback): Adjust to
3244 handle biased address.
3245 * device_table.c (console_io_write_buffer_callback): Ditto
3247 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3249 * device.c (attach_device_interrupt_edge): New. Interrupt model
3250 did not allow interrupts to be wired up as a general net (edges).
3251 Re-implement so that interrupt events can be passed to multiple
3252 controllers and interrupt controllers can further propogate
3255 * device.c (attach_device_interrupt_edge) : New, Ditto
3256 * device.c (detach_device_interrupt_edge) : New, Ditto
3257 * device.c (clean_device_interrupt_edges) : New, Ditto
3258 * device.c (device_interrupt_event) : New, Ditto
3259 * device.c (device_interrupt_attach) : New, Ditto
3260 * device.c (device_interrupt_detach) : New, Ditto
3261 * device.c (device_child_interrupt_attach) : New, Ditto
3262 * device.c (device_child_interrupt_detach) : New, Ditto
3264 * device.c (device_attach_interrupt) : Delete old
3265 * device.c (device_detach_interrupt) : Delete old
3266 * device.c (device_interrupt) : Delete old
3267 * device.c (device_interrupt_ack) : Delete old
3269 * device_table.c (unimp_*) : Update to match
3271 * device_table.c (icu_io_write_buffer_callback) : Update to use
3273 * device_table.c (icu_interrupt_event_callback) : Ditto
3275 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3277 * device.c (external_to_device) : New function that provides a
3278 standard mapping between a devices internal representation (a
3279 pointer) and its external (or what is passed to a client)
3280 representation (a phandle). Implement using the cap object
3281 attached to the root node.
3283 * device.c (device_to_external) : Ditto
3284 * device.c (external_to_device_instance) : Ditto but for ihandle
3285 and device instance.
3286 * device.c (device_instance_to_external) : Ditto
3288 * Makefile (device.o): Add dependency on cap.
3290 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3291 needing to translate between internal and external representations
3292 changed to use the external_to_device et.al. device operations.
3293 * emul_chirp.c (chirp_emul_*) : Ditto
3295 * Makefile (emul_chirp.o): Remove dependency on cap
3297 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3299 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3300 on OpenBoot note section.
3302 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3304 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3305 read/write calls for buffer transfers. This will cause a fault to
3306 occure if the transfer fails. CHRP catches the fault while the
3307 others suffer the consequences.
3308 (emul_read_buffer): Ditto.
3309 (emul_write_word): Ditto.
3310 (emul_read_word): Ditto.
3311 (emul_read_string): Ditto.
3313 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3315 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3316 emul_generic (emul_blr_instruction): Use a real blr instruction to
3317 return from a client service call.
3319 * emul_chirp.c (services): Add all OpenBoot services to table.
3321 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3322 (emul_chirp_create) : Use names instead of numbers for
3323 instructions being stored in memory.
3325 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3327 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3328 (From NetBSD) files.
3330 Wed May 29 22:57:40 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
3332 * ChangeLog.00, ChangeLog: ChangeLog from gdb-4.16 becomes
