1103 open syscall to the numbers supported by the host.
1105 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
1107 * sim-endian.h: Don't have parameters on macro definitions which
1108 are simply renaming functions, to permit use of XCONCAT2 in both
1109 the macro name and the arguments in a use of such a definition.
1111 2000-11-15 Jim Blandy <jimb@redhat.com>
1113 * sim_calls.c: Doc fix.
1114 (sim_fetch_register, sim_store_register): Call
1115 gdbarch_register_name directly, instead of going through
1116 REGISTER_NAME macro.
1118 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1120 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1145 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
1147 * configure: Regenerated to track ../common/aclocal.m4 changes.
1149 1999-05-08 Felix Lee <flee@cygnus.com>
1151 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1152 * configure: Regenerated to track ../common/aclocal.m4 changes.
1154 1999-04-02 Keith Seitz <keiths@cygnus.com>
1156 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
1157 the frequency at which the poll_quit callback is called.
1158 (poll_quit_count): New global.
1159 (sim_io_poll_quit): Only call the poll_quit callback
1160 after the specified POLL_QUIT_INTERVAL.
1162 1999-02-22 Jim Lemke <jlemke@cygnus.com>
1164 * dc-complex: Force expansion on all bits of field BO.
1165 Previously, the least-significant (prediction) bit was ignored.
1166 * ppc-instructions (conditional branches): Implement mpc860c0 option.
1167 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
1168 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
1169 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
1170 * interrupts.c (program_interrupt): Added handling for above interrupt.
1172 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1174 Make the simulator compatible with the MPC750. It would be nicer
1175 to make this a real multi-sim, but that's more work than we have
1177 * emul_generic.c (emul_add_tree_options): Only require strict
1178 alignment if it was explicitly requested at configuration time.
1179 Don't make it the default for little-endian machines.
1180 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1181 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1182 THRM2, THRM3): Plop in the MPC750 SPR registers.
1183 (DABR): This is weird. This was HID5, but the PPC spec says this
1184 should be DABR; why did some random processor use it for something
1185 else? The HID5 entry dates back to the original checkin of the
1186 simulator code in 1995, so remove it.
1187 * sim_calls.c (register_names): Delete this; since the user can
1188 now change GDB's list of register names dynamically, we can't
1189 pretend there's a static mapping here.
1190 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1191 function to get the register name. That ought to be accurate.
1192 However, we're changing a compile-time dependency (using the
1193 REGISTER_NAMES macro) into a link- and run-time dependency
1194 (calling REGISTER_NAME, which happens to be a function call on the
1197 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1199 * igen.c(gen_semantics_[ch]): setup/use of new option

1223 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1224 fractional type, so that quiet NaN's aren't treated like
1227 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1229 * table.c (table_open): For cygwin hosts, we need to use the
1230 return value from the read routine as the number of bytes to
1231 process. This apparently is due to text-mode vs binary-mode. If
1232 the mounts are done text-mode, then the size returnedby fstat()
1233 may be different than the number of bytes "read" in text mode.
1235 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1237 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1254 * configure: Regenerate.
1255 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1256 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1258 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1260 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1261 but there was no such target, only plain psim. So I changed the
1262 run target to depend on psim.
1264 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1266 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1267 now defined in ../common/aclocal.m4, and the double definition causes
1268 problems with AC_SUBST of EXEEXT.

1357 mask extracting shift amount. Correctly condition for setting XER
1359 (ldhau): From Johannes Reisinger, update rA after load.
1361 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>

1606 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1607 works for normal and boolean table entries.
1609 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1631 * gen-idecode.c: Correct generated igen body so that it no drops
1632 or doubles clock interrupts.
1635 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1637 * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to

1670 determine the simulation speed by looking at the number of elapsed
1671 ticks recorded by the event queue.
1673 * psim.c (psim_write_register, psim_read_register): Force the cpu
1674 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1675 next cpu would be zero any way.
1677 * mon.c (mon_print_info): If possible, print the system cycle
1678 performance. This is an indication of the number of instructions
1681 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1683 * The code to allow an event queue to be updated during a signal
1684 was missing. For main.c, a cntrl-c simulation termination wasn't
1687 * The simulation would not correctly restart if an event requested
1688 that the simulation be halted.
1690 * psim.c (psim_options): Add hack to -i option to optionally
1691 include a level vis -i2.
1692 (psim_usage): Document.

1711 * gen-idecode.c (print_run_until_stop_body): Call
1712 event_queue_process_events to clear possibly pending events before
1713 starting a simulation run. Re-arange main loop so that simulator
1714 is correctly restarted when an event halts the simulation.

1740 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1741 to be initialized independant of the rest of the simulation
1742 initalization. Otherwize a trace option explictly set from gdb
1743 could be overridden by hw_trace.
1745 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1747 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1748 debug.c. It could be much simpler.
1750 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1790 the form <name>_is_<const> where it is a boolean field, generate
1791 the result of the expression instead of the expression its self.

1795 * gen-icache.c (print_icache_struct): If there is no cache, do not
1796 output expressions in idecode.h file.
1798 * gen-icache.c (print_icache_body): Output them here.

1807 * The code that put values in and extracted values from the cache
1808 was too compilicated. The cache table did not allow values to be
1809 computed from cache entries. #defines could only be used when a
1810 cache was present, remove the restriction.
1812 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1813 scratch variable is defined when a cache entry is beinf
1814 filled. Change the definition of a COMPUTE variable to be defined
1815 when the cache entry is being used.
1816 * gen-icache.c: Update.
1818 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1831 * igen.c (main): Change 'R' option so that it does not force the
1834 * configure.in (enable-sim-icache): Clarify description. Make
1835 #define one of the defaults regardless of the cache. Probably
1836 should revamp and add a separate option.

4224 * corefile.c (core_create, core_device_create): Adjust so that the
4225 core device is created earlier for psim_tree(). Core can later be
4228 * psim.c (psim_create): Update to handle above way of creating
4229 things. Extract all information from the device tree.
4231 * device_tree.c (trace_*): New device node, its properties are
4232 used to set the value of the trace options. Init this device (in
4233 psim_options) when ever the options are updated.
4235 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
4237 * debug.h: Add trace_print_info, trace_print_device_tree and
4238 trace_dump_device_tree. The first is a replacement for the
4239 variable `print_info' found in main.c and sim_calls.c. The latter
4240 two enable the dumping of the entire device tree.
4242 * debug.c: Add to trace_description table.
4244 * main.c (main): Use above trace instead of local variable
4245 * sim_calls.c (sim_close): Ditto
4247 * device.c (device_tree_print_device): New. Prints the device
4248 tree in a format that is consistent with what can be parsed by the
4249 device tree load from file code.
4251 * psim.c (psim_create): Dump device tree if enabled. If nump
4252 selected, exit psim immediately.
4254 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
4256 * corefile-n.h (core_map_read_N): When mapping from an address to
4257 a device, do not subtract the devices base. The device its self
4258 can do this. Brings the behavour into line with OpenBoot.
4259 * corefile-n.h (core_map_write_N): Ditto
4260 * corefile.c (core_map_read_buffer): Ditto
4261 * corefile.c (core_map_write_buffer): Ditto
4263 * device_table.c (console_io_read_buffer_callback): Adjust to
4264 handle biased address.
4265 * device_table.c (console_io_write_buffer_callback): Ditto
4267 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
4269 * device.c (attach_device_interrupt_edge): New. Interrupt model
4270 did not allow interrupts to be wired up as a general net (edges).
4271 Re-implement so that interrupt events can be passed to multiple
4272 controllers and interrupt controllers can further propogate
4275 * device.c (attach_device_interrupt_edge) : New, Ditto
4276 * device.c (detach_device_interrupt_edge) : New, Ditto
4277 * device.c (clean_device_interrupt_edges) : New, Ditto
4278 * device.c (device_interrupt_event) : New, Ditto
4279 * device.c (device_interrupt_attach) : New, Ditto
4280 * device.c (device_interrupt_detach) : New, Ditto
4281 * device.c (device_child_interrupt_attach) : New, Ditto
4282 * device.c (device_child_interrupt_detach) : New, Ditto
4284 * device.c (device_attach_interrupt) : Delete old
4285 * device.c (device_detach_interrupt) : Delete old
4286 * device.c (device_interrupt) : Delete old
4287 * device.c (device_interrupt_ack) : Delete old
4289 * device_table.c (unimp_*) : Update to match
4291 * device_table.c (icu_io_write_buffer_callback) : Update to use
4293 * device_table.c (icu_interrupt_event_callback) : Ditto
4295 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
4297 * device.c (external_to_device) : New function that provides a
4298 standard mapping between a devices internal representation (a
4299 pointer) and its external (or what is passed to a client)
4300 representation (a phandle). Implement using the cap object
4301 attached to the root node.
4303 * device.c (device_to_external) : Ditto
4304 * device.c (external_to_device_instance) : Ditto but for ihandle
4305 and device instance.
4306 * device.c (device_instance_to_external) : Ditto
4308 * Makefile (device.o): Add dependency on cap.
4310 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
4311 needing to translate between internal and external representations
4312 changed to use the external_to_device et.al. device operations.
4313 * emul_chirp.c (chirp_emul_*) : Ditto
4315 * Makefile (emul_chirp.o): Remove dependency on cap
4317 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
4319 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
4320 on OpenBoot note section.
4322 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
4324 * emul_generic.c (emul_write_buffer): Use vm faulting byte
4325 read/write calls for buffer transfers. This will cause a fault to
4326 occure if the transfer fails. CHRP catches the fault while the
4327 others suffer the consequences.
4328 (emul_read_buffer): Ditto.
4329 (emul_write_word): Ditto.
4330 (emul_read_word): Ditto.
4331 (emul_read_string): Ditto.
4333 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
4335 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
4336 emul_generic (emul_blr_instruction): Use a real blr instruction to
4337 return from a client service call.
4339 * emul_chirp.c (services): Add all OpenBoot services to table.
4341 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
4342 (emul_chirp_create) : Use names instead of numbers for
4343 instructions being stored in memory.
4345 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
4347 * Makefile.in (maintainer-clean): Remove .log, core and *.core
4348 (From NetBSD) files.
