1122 open syscall to the numbers supported by the host.
1124 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
1126 * sim-endian.h: Don't have parameters on macro definitions which
1127 are simply renaming functions, to permit use of XCONCAT2 in both
1128 the macro name and the arguments in a use of such a definition.
1130 2000-11-15 Jim Blandy <jimb@redhat.com>
1132 * sim_calls.c: Doc fix.
1133 (sim_fetch_register, sim_store_register): Call
1134 gdbarch_register_name directly, instead of going through
1135 REGISTER_NAME macro.
1137 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1139 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1168 1999-05-08 Felix Lee <flee@cygnus.com>
1170 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1171 * configure: Regenerated to track ../common/aclocal.m4 changes.
1173 1999-04-02 Keith Seitz <keiths@cygnus.com>
1175 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
1176 the frequency at which the poll_quit callback is called.

1178 (sim_io_poll_quit): Only call the poll_quit callback
1179 after the specified POLL_QUIT_INTERVAL.
1181 1999-02-22 Jim Lemke <jlemke@cygnus.com>
1183 * dc-complex: Force expansion on all bits of field BO.
1184 Previously, the least-significant (prediction) bit was ignored.
1185 * ppc-instructions (conditional branches): Implement mpc860c0 option.
1186 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
1187 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

1189 * interrupts.c (program_interrupt): Added handling for above interrupt.
1191 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1193 Make the simulator compatible with the MPC750. It would be nicer
1194 to make this a real multi-sim, but that's more work than we have
1196 * emul_generic.c (emul_add_tree_options): Only require strict
1197 alignment if it was explicitly requested at configuration time.
1198 Don't make it the default for little-endian machines.
1199 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1200 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1201 THRM2, THRM3): Plop in the MPC750 SPR registers.
1202 (DABR): This is weird. This was HID5, but the PPC spec says this
1203 should be DABR; why did some random processor use it for something
1204 else? The HID5 entry dates back to the original checkin of the
1205 simulator code in 1995, so remove it.
1206 * sim_calls.c (register_names): Delete this; since the user can
1207 now change GDB's list of register names dynamically, we can't
1208 pretend there's a static mapping here.
1209 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1210 function to get the register name. That ought to be accurate.
1211 However, we're changing a compile-time dependency (using the
1212 REGISTER_NAMES macro) into a link- and run-time dependency
1213 (calling REGISTER_NAME, which happens to be a function call on the
1216 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1218 * igen.c(gen_semantics_[ch]): setup/use of new option

1242 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1243 fractional type, so that quiet NaN's aren't treated like
1246 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1248 * table.c (table_open): For cygwin hosts, we need to use the
1249 return value from the read routine as the number of bytes to
1250 process. This apparently is due to text-mode vs binary-mode. If
1251 the mounts are done text-mode, then the size returnedby fstat()
1252 may be different than the number of bytes "read" in text mode.
1254 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

1273 * configure: Regenerate.
1274 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1275 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1277 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1279 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1280 but there was no such target, only plain psim. So I changed the
1281 run target to depend on psim.
1283 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1285 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1286 now defined in ../common/aclocal.m4, and the double definition causes
1287 problems with AC_SUBST of EXEEXT.

1376 mask extracting shift amount. Correctly condition for setting XER
1378 (ldhau): From Johannes Reisinger, update rA after load.
1380 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>

1689 determine the simulation speed by looking at the number of elapsed
1690 ticks recorded by the event queue.
1692 * psim.c (psim_write_register, psim_read_register): Force the cpu
1693 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1694 next cpu would be zero any way.
1696 * mon.c (mon_print_info): If possible, print the system cycle
1697 performance. This is an indication of the number of instructions
1700 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1702 * The code to allow an event queue to be updated during a signal
1703 was missing. For main.c, a cntrl-c simulation termination wasn't
1706 * The simulation would not correctly restart if an event requested
1707 that the simulation be halted.
1709 * psim.c (psim_options): Add hack to -i option to optionally
1710 include a level vis -i2.
1711 (psim_usage): Document.

1730 * gen-idecode.c (print_run_until_stop_body): Call
1731 event_queue_process_events to clear possibly pending events before

1759 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1760 to be initialized independant of the rest of the simulation
1761 initalization. Otherwize a trace option explictly set from gdb
1762 could be overridden by hw_trace.
1764 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1766 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1767 debug.c. It could be much simpler.

1815 output expressions in idecode.h file.
1817 * gen-icache.c (print_icache_body): Output them here.

1827 was too compilicated. The cache table did not allow values to be
1828 computed from cache entries. #defines could only be used when a
1829 cache was present, remove the restriction.
1831 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1832 scratch variable is defined when a cache entry is beinf
1833 filled. Change the definition of a COMPUTE variable to be defined
1834 when the cache entry is being used.
1835 * gen-icache.c: Update.
1837 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1853 * configure.in (enable-sim-icache): Clarify description. Make
1854 #define one of the defaults regardless of the cache. Probably
1855 should revamp and add a separate option.

4227 * psim.c (psim_usage): New. Give usage to varing levels of detail
4228 according to the verbosity. In turn output device and trace
4231 * main.c (main): Update to use new system
4232 * sim_calls.c (sim_open, sim_do_command): Ditto
4234 * psim.c (psim_options): Add `r' option - ram size.
4235 * psim.c (psim_options): Add `o' option - openboot tree entry.
4236 * psim.c (psim_options): Add `h'/`H' options - more help.
4238 * debug.c (trace_usage): Add more detailed help.
4239 * device.c (device_usage): New. Output help including a list of
4240 the devices currently available in the device table.

4244 core device is created earlier for psim_tree(). Core can later be
4247 * psim.c (psim_create): Update to handle above way of creating
4248 things. Extract all information from the device tree.
4250 * device_tree.c (trace_*): New device node, its properties are
4251 used to set the value of the trace options. Init this device (in
4252 psim_options) when ever the options are updated.
4254 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
4256 * debug.h: Add trace_print_info, trace_print_device_tree and
4257 trace_dump_device_tree. The first is a replacement for the
4258 variable `print_info' found in main.c and sim_calls.c. The latter
4259 two enable the dumping of the entire device tree.
4261 * debug.c: Add to trace_description table.
4263 * main.c (main): Use above trace instead of local variable
4264 * sim_calls.c (sim_close): Ditto
4266 * device.c (device_tree_print_device): New. Prints the device
4267 tree in a format that is consistent with what can be parsed by the
4268 device tree load from file code.
4270 * psim.c (psim_create): Dump device tree if enabled. If nump
4271 selected, exit psim immediately.
4273 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
4275 * corefile-n.h (core_map_read_N): When mapping from an address to
4276 a device, do not subtract the devices base. The device its self
4277 can do this. Brings the behavour into line with OpenBoot.
4278 * corefile-n.h (core_map_write_N): Ditto
4279 * corefile.c (core_map_read_buffer): Ditto
4280 * corefile.c (core_map_write_buffer): Ditto
4282 * device_table.c (console_io_read_buffer_callback): Adjust to
4283 handle biased address.
4284 * device_table.c (console_io_write_buffer_callback): Ditto
4286 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
4288 * device.c (attach_device_interrupt_edge): New. Interrupt model
4289 did not allow interrupts to be wired up as a general net (edges).
4290 Re-implement so that interrupt events can be passed to multiple
4291 controllers and interrupt controllers can further propogate
4294 * device.c (attach_device_interrupt_edge) : New, Ditto
4295 * device.c (detach_device_interrupt_edge) : New, Ditto
4296 * device.c (clean_device_interrupt_edges) : New, Ditto
4297 * device.c (device_interrupt_event) : New, Ditto
4298 * device.c (device_interrupt_attach) : New, Ditto
4299 * device.c (device_interrupt_detach) : New, Ditto
4300 * device.c (device_child_interrupt_attach) : New, Ditto
4301 * device.c (device_child_interrupt_detach) : New, Ditto
4303 * device.c (device_attach_interrupt) : Delete old
4304 * device.c (device_detach_interrupt) : Delete old
4305 * device.c (device_interrupt) : Delete old
4306 * device.c (device_interrupt_ack) : Delete old
4308 * device_table.c (unimp_*) : Update to match
4310 * device_table.c (icu_io_write_buffer_callback) : Update to use
4312 * device_table.c (icu_interrupt_event_callback) : Ditto
4314 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
4316 * device.c (external_to_device) : New function that provides a
4317 standard mapping between a devices internal representation (a
4318 pointer) and its external (or what is passed to a client)
4319 representation (a phandle). Implement using the cap object
4320 attached to the root node.
4322 * device.c (device_to_external) : Ditto
4323 * device.c (external_to_device_instance) : Ditto but for ihandle
4324 and device instance.
4325 * device.c (device_instance_to_external) : Ditto
4327 * Makefile (device.o): Add dependency on cap.
4329 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
4330 needing to translate between internal and external representations
4331 changed to use the external_to_device et.al. device operations.
4332 * emul_chirp.c (chirp_emul_*) : Ditto
4334 * Makefile (emul_chirp.o): Remove dependency on cap
4336 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
4338 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
4339 on OpenBoot note section.
4341 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
4343 * emul_generic.c (emul_write_buffer): Use vm faulting byte
4344 read/write calls for buffer transfers. This will cause a fault to
4345 occure if the transfer fails. CHRP catches the fault while the
4346 others suffer the consequences.
4347 (emul_read_buffer): Ditto.
4348 (emul_write_word): Ditto.
4349 (emul_read_word): Ditto.
4350 (emul_read_string): Ditto.
4352 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
4354 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
4355 emul_generic (emul_blr_instruction): Use a real blr instruction to
