1097 open syscall to the numbers supported by the host.
1099 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
1101 * sim-endian.h: Don't have parameters on macro definitions which
1102 are simply renaming functions, to permit use of XCONCAT2 in both
1103 the macro name and the arguments in a use of such a definition.
1105 2000-11-15 Jim Blandy <jimb@redhat.com>
1107 * sim_calls.c: Doc fix.
1108 (sim_fetch_register, sim_store_register): Call
1109 gdbarch_register_name directly, instead of going through
1110 REGISTER_NAME macro.
1112 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1114 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1139 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
1141 * configure: Regenerated to track ../common/aclocal.m4 changes.
1143 1999-05-08 Felix Lee <flee@cygnus.com>
1145 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1146 * configure: Regenerated to track ../common/aclocal.m4 changes.
1148 1999-04-02 Keith Seitz <keiths@cygnus.com>
1150 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
1151 the frequency at which the poll_quit callback is called.

1153 (sim_io_poll_quit): Only call the poll_quit callback
1154 after the specified POLL_QUIT_INTERVAL.
1156 1999-02-22 Jim Lemke <jlemke@cygnus.com>
1158 * dc-complex: Force expansion on all bits of field BO.
1159 Previously, the least-significant (prediction) bit was ignored.
1160 * ppc-instructions (conditional branches): Implement mpc860c0 option.
1161 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
1162 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

1164 * interrupts.c (program_interrupt): Added handling for above interrupt.
1166 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1168 Make the simulator compatible with the MPC750. It would be nicer
1169 to make this a real multi-sim, but that's more work than we have
1171 * emul_generic.c (emul_add_tree_options): Only require strict
1172 alignment if it was explicitly requested at configuration time.
1173 Don't make it the default for little-endian machines.
1174 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1175 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1176 THRM2, THRM3): Plop in the MPC750 SPR registers.
1177 (DABR): This is weird. This was HID5, but the PPC spec says this
1178 should be DABR; why did some random processor use it for something
1179 else? The HID5 entry dates back to the original checkin of the
1180 simulator code in 1995, so remove it.
1181 * sim_calls.c (register_names): Delete this; since the user can
1182 now change GDB's list of register names dynamically, we can't
1183 pretend there's a static mapping here.
1184 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1185 function to get the register name. That ought to be accurate.
1186 However, we're changing a compile-time dependency (using the
1187 REGISTER_NAMES macro) into a link- and run-time dependency
1188 (calling REGISTER_NAME, which happens to be a function call on the
1191 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1193 * igen.c(gen_semantics_[ch]): setup/use of new option

1217 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1218 fractional type, so that quiet NaN's aren't treated like
1221 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1223 * table.c (table_open): For cygwin hosts, we need to use the
1224 return value from the read routine as the number of bytes to
1225 process. This apparently is due to text-mode vs binary-mode. If
1226 the mounts are done text-mode, then the size returnedby fstat()
1227 may be different than the number of bytes "read" in text mode.
1229 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

1252 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1254 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1255 but there was no such target, only plain psim. So I changed the
1256 run target to depend on psim.
1258 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1260 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1261 now defined in ../common/aclocal.m4, and the double definition causes

1351 mask extracting shift amount. Correctly condition for setting XER
1353 (ldhau): From Johannes Reisinger, update rA after load.
1355 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>

1664 determine the simulation speed by looking at the number of elapsed
1665 ticks recorded by the event queue.
1667 * psim.c (psim_write_register, psim_read_register): Force the cpu
1668 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1669 next cpu would be zero any way.
1671 * mon.c (mon_print_info): If possible, print the system cycle
1672 performance. This is an indication of the number of instructions
1675 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1677 * The code to allow an event queue to be updated during a signal
1678 was missing. For main.c, a cntrl-c simulation termination wasn't
1681 * The simulation would not correctly restart if an event requested
1682 that the simulation be halted.
1684 * psim.c (psim_options): Add hack to -i option to optionally
1685 include a level vis -i2.
1686 (psim_usage): Document.

1705 * gen-idecode.c (print_run_until_stop_body): Call
1706 event_queue_process_events to clear possibly pending events before

1734 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1735 to be initialized independant of the rest of the simulation
1736 initalization. Otherwize a trace option explictly set from gdb
1737 could be overridden by hw_trace.
1739 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1741 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1742 debug.c. It could be much simpler.

1784 the form <name>_is_<const> where it is a boolean field, generate
1785 the result of the expression instead of the expression its self.

1801 * The code that put values in and extracted values from the cache
1802 was too compilicated. The cache table did not allow values to be
1803 computed from cache entries. #defines could only be used when a
1804 cache was present, remove the restriction.
1806 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1807 scratch variable is defined when a cache entry is beinf
1808 filled. Change the definition of a COMPUTE variable to be defined
1809 when the cache entry is being used.
1810 * gen-icache.c: Update.
1812 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1825 * igen.c (main): Change 'R' option so that it does not force the
1828 * configure.in (enable-sim-icache): Clarify description. Make
1829 #define one of the defaults regardless of the cache. Probably
1830 should revamp and add a separate option.

4226 used to set the value of the trace options. Init this device (in
4227 psim_options) when ever the options are updated.
4229 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
4231 * debug.h: Add trace_print_info, trace_print_device_tree and
4232 trace_dump_device_tree. The first is a replacement for the
4233 variable `print_info' found in main.c and sim_calls.c. The latter
4234 two enable the dumping of the entire device tree.
4236 * debug.c: Add to trace_description table.
4238 * main.c (main): Use above trace instead of local variable
4239 * sim_calls.c (sim_close): Ditto
4241 * device.c (device_tree_print_device): New. Prints the device
4242 tree in a format that is consistent with what can be parsed by the
4243 device tree load from file code.
4245 * psim.c (psim_create): Dump device tree if enabled. If nump
4246 selected, exit psim immediately.
4248 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
4250 * corefile-n.h (core_map_read_N): When mapping from an address to
4251 a device, do not subtract the devices base. The device its self
4252 can do this. Brings the behavour into line with OpenBoot.
4253 * corefile-n.h (core_map_write_N): Ditto
4254 * corefile.c (core_map_read_buffer): Ditto
4255 * corefile.c (core_map_write_buffer): Ditto
4257 * device_table.c (console_io_read_buffer_callback): Adjust to
4258 handle biased address.
4259 * device_table.c (console_io_write_buffer_callback): Ditto
4261 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
4263 * device.c (attach_device_interrupt_edge): New. Interrupt model
4264 did not allow interrupts to be wired up as a general net (edges).
4265 Re-implement so that interrupt events can be passed to multiple
4266 controllers and interrupt controllers can further propogate
4269 * device.c (attach_device_interrupt_edge) : New, Ditto
4270 * device.c (detach_device_interrupt_edge) : New, Ditto
4271 * device.c (clean_device_interrupt_edges) : New, Ditto
4272 * device.c (device_interrupt_event) : New, Ditto
4273 * device.c (device_interrupt_attach) : New, Ditto
4274 * device.c (device_interrupt_detach) : New, Ditto
4275 * device.c (device_child_interrupt_attach) : New, Ditto
4276 * device.c (device_child_interrupt_detach) : New, Ditto
4278 * device.c (device_attach_interrupt) : Delete old
4279 * device.c (device_detach_interrupt) : Delete old
4280 * device.c (device_interrupt) : Delete old
4281 * device.c (device_interrupt_ack) : Delete old
4283 * device_table.c (unimp_*) : Update to match
4285 * device_table.c (icu_io_write_buffer_callback) : Update to use
4287 * device_table.c (icu_interrupt_event_callback) : Ditto
4289 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
4291 * device.c (external_to_device) : New function that provides a
4292 standard mapping between a devices internal representation (a
4293 pointer) and its external (or what is passed to a client)
4294 representation (a phandle). Implement using the cap object
4295 attached to the root node.
4297 * device.c (device_to_external) : Ditto
4298 * device.c (external_to_device_instance) : Ditto but for ihandle
4299 and device instance.
4300 * device.c (device_instance_to_external) : Ditto
4302 * Makefile (device.o): Add dependency on cap.
4304 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
4305 needing to translate between internal and external representations
4306 changed to use the external_to_device et.al. device operations.
4307 * emul_chirp.c (chirp_emul_*) : Ditto
4309 * Makefile (emul_chirp.o): Remove dependency on cap
4311 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
4313 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
4314 on OpenBoot note section.
4316 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
4318 * emul_generic.c (emul_write_buffer): Use vm faulting byte
4319 read/write calls for buffer transfers. This will cause a fault to
4320 occure if the transfer fails. CHRP catches the fault while the
4321 others suffer the consequences.
4322 (emul_read_buffer): Ditto.
4323 (emul_write_word): Ditto.
4324 (emul_read_word): Ditto.
4325 (emul_read_string): Ditto.
4327 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
4329 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
4330 emul_generic (emul_blr_instruction): Use a real blr instruction to
4331 return from a client service call.
4333 * emul_chirp.c (services): Add all OpenBoot services to table.
4335 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
4336 (emul_chirp_create) : Use names instead of numbers for
4337 instructions being stored in memory.
4339 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
4341 * Makefile.in (maintainer-clean): Remove .log, core and *.core
4342 (From NetBSD) files.
4344 Wed May 29 22:57:40 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
4346 * ChangeLog.00, ChangeLog: ChangeLog from gdb-4.16 becomes
