1081 open syscall to the numbers supported by the host.
1083 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
1085 * sim-endian.h: Don't have parameters on macro definitions which
1086 are simply renaming functions, to permit use of XCONCAT2 in both
1087 the macro name and the arguments in a use of such a definition.
1089 2000-11-15 Jim Blandy <jimb@redhat.com>
1091 * sim_calls.c: Doc fix.
1092 (sim_fetch_register, sim_store_register): Call
1093 gdbarch_register_name directly, instead of going through
1094 REGISTER_NAME macro.
1096 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1098 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1121 the exponent when denormalizing.
1123 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
1125 * configure: Regenerated to track ../common/aclocal.m4 changes.
1127 1999-05-08 Felix Lee <flee@cygnus.com>
1129 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1130 * configure: Regenerated to track ../common/aclocal.m4 changes.
1132 1999-04-02 Keith Seitz <keiths@cygnus.com>
1134 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
1135 the frequency at which the poll_quit callback is called.
1136 (poll_quit_count): New global.
1137 (sim_io_poll_quit): Only call the poll_quit callback
1138 after the specified POLL_QUIT_INTERVAL.
1140 1999-02-22 Jim Lemke <jlemke@cygnus.com>
1142 * dc-complex: Force expansion on all bits of field BO.
1143 Previously, the least-significant (prediction) bit was ignored.
1144 * ppc-instructions (conditional branches): Implement mpc860c0 option.
1145 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
1146 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
1147 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
1148 * interrupts.c (program_interrupt): Added handling for above interrupt.
1150 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1152 Make the simulator compatible with the MPC750. It would be nicer
1153 to make this a real multi-sim, but that's more work than we have
1155 * emul_generic.c (emul_add_tree_options): Only require strict
1156 alignment if it was explicitly requested at configuration time.
1157 Don't make it the default for little-endian machines.
1158 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1159 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1160 THRM2, THRM3): Plop in the MPC750 SPR registers.
1161 (DABR): This is weird. This was HID5, but the PPC spec says this
1162 should be DABR; why did some random processor use it for something
1163 else? The HID5 entry dates back to the original checkin of the
1164 simulator code in 1995, so remove it.
1165 * sim_calls.c (register_names): Delete this; since the user can
1166 now change GDB's list of register names dynamically, we can't
1167 pretend there's a static mapping here.
1168 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1169 function to get the register name. That ought to be accurate.
1170 However, we're changing a compile-time dependency (using the
1171 REGISTER_NAMES macro) into a link- and run-time dependency
1172 (calling REGISTER_NAME, which happens to be a function call on the
1175 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1177 * igen.c(gen_semantics_[ch]): setup/use of new option

1201 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1202 fractional type, so that quiet NaN's aren't treated like
1205 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1207 * table.c (table_open): For cygwin hosts, we need to use the
1208 return value from the read routine as the number of bytes to
1209 process. This apparently is due to text-mode vs binary-mode. If
1210 the mounts are done text-mode, then the size returnedby fstat()
1211 may be different than the number of bytes "read" in text mode.
1213 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

1232 * configure: Regenerate.
1233 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1234 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1236 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1238 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1239 but there was no such target, only plain psim. So I changed the
1240 run target to depend on psim.
1242 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1244 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1245 now defined in ../common/aclocal.m4, and the double definition causes
1246 problems with AC_SUBST of EXEEXT.

1335 mask extracting shift amount. Correctly condition for setting XER
1337 (ldhau): From Johannes Reisinger, update rA after load.
1339 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>

1651 * psim.c (psim_write_register, psim_read_register): Force the cpu
1652 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1653 next cpu would be zero any way.
1655 * mon.c (mon_print_info): If possible, print the system cycle
1656 performance. This is an indication of the number of instructions
1659 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1661 * The code to allow an event queue to be updated during a signal
1662 was missing. For main.c, a cntrl-c simulation termination wasn't
1665 * The simulation would not correctly restart if an event requested
1666 that the simulation be halted.
1668 * psim.c (psim_options): Add hack to -i option to optionally
1669 include a level vis -i2.
1670 (psim_usage): Document.

1689 * gen-idecode.c (print_run_until_stop_body): Call
1690 event_queue_process_events to clear possibly pending events before

1718 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1719 to be initialized independant of the rest of the simulation
1720 initalization. Otherwize a trace option explictly set from gdb
1721 could be overridden by hw_trace.
1723 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1725 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1726 debug.c. It could be much simpler.

1786 was too compilicated. The cache table did not allow values to be
1787 computed from cache entries. #defines could only be used when a
1788 cache was present, remove the restriction.
1790 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1791 scratch variable is defined when a cache entry is beinf
1792 filled. Change the definition of a COMPUTE variable to be defined
1793 when the cache entry is being used.
1794 * gen-icache.c: Update.
1796 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1812 * configure.in (enable-sim-icache): Clarify description. Make
1813 #define one of the defaults regardless of the cache. Probably
1814 should revamp and add a separate option.

4220 * debug.c: Add to trace_description table.
4222 * main.c (main): Use above trace instead of local variable
4223 * sim_calls.c (sim_close): Ditto
4225 * device.c (device_tree_print_device): New. Prints the device
4226 tree in a format that is consistent with what can be parsed by the
4227 device tree load from file code.
4229 * psim.c (psim_create): Dump device tree if enabled. If nump
4230 selected, exit psim immediately.
4232 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
4234 * corefile-n.h (core_map_read_N): When mapping from an address to
4235 a device, do not subtract the devices base. The device its self
4236 can do this. Brings the behavour into line with OpenBoot.
4237 * corefile-n.h (core_map_write_N): Ditto
4238 * corefile.c (core_map_read_buffer): Ditto
4239 * corefile.c (core_map_write_buffer): Ditto
4241 * device_table.c (console_io_read_buffer_callback): Adjust to
4242 handle biased address.
4243 * device_table.c (console_io_write_buffer_callback): Ditto
4245 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
4247 * device.c (attach_device_interrupt_edge): New. Interrupt model
4248 did not allow interrupts to be wired up as a general net (edges).
4249 Re-implement so that interrupt events can be passed to multiple
4250 controllers and interrupt controllers can further propogate
4253 * device.c (attach_device_interrupt_edge) : New, Ditto
4254 * device.c (detach_device_interrupt_edge) : New, Ditto
4255 * device.c (clean_device_interrupt_edges) : New, Ditto
4256 * device.c (device_interrupt_event) : New, Ditto
4257 * device.c (device_interrupt_attach) : New, Ditto
4258 * device.c (device_interrupt_detach) : New, Ditto
4259 * device.c (device_child_interrupt_attach) : New, Ditto
4260 * device.c (device_child_interrupt_detach) : New, Ditto
4262 * device.c (device_attach_interrupt) : Delete old
4263 * device.c (device_detach_interrupt) : Delete old
4264 * device.c (device_interrupt) : Delete old
4265 * device.c (device_interrupt_ack) : Delete old
4267 * device_table.c (unimp_*) : Update to match
4269 * device_table.c (icu_io_write_buffer_callback) : Update to use
4271 * device_table.c (icu_interrupt_event_callback) : Ditto
4273 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
4275 * device.c (external_to_device) : New function that provides a
4276 standard mapping between a devices internal representation (a
4277 pointer) and its external (or what is passed to a client)
4278 representation (a phandle). Implement using the cap object
4279 attached to the root node.
4281 * device.c (device_to_external) : Ditto
4282 * device.c (external_to_device_instance) : Ditto but for ihandle
4283 and device instance.
4284 * device.c (device_instance_to_external) : Ditto
4286 * Makefile (device.o): Add dependency on cap.
4288 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
4289 needing to translate between internal and external representations
4290 changed to use the external_to_device et.al. device operations.
4291 * emul_chirp.c (chirp_emul_*) : Ditto
4293 * Makefile (emul_chirp.o): Remove dependency on cap
4295 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
4297 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
4298 on OpenBoot note section.
4300 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
4302 * emul_generic.c (emul_write_buffer): Use vm faulting byte
4303 read/write calls for buffer transfers. This will cause a fault to
4304 occure if the transfer fails. CHRP catches the fault while the
4305 others suffer the consequences.
4306 (emul_read_buffer): Ditto.
4307 (emul_write_word): Ditto.
4308 (emul_read_word): Ditto.
4309 (emul_read_string): Ditto.
4311 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
4313 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
4314 emul_generic (emul_blr_instruction): Use a real blr instruction to
4315 return from a client service call.
4317 * emul_chirp.c (services): Add all OpenBoot services to table.
4319 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
4320 (emul_chirp_create) : Use names instead of numbers for
4321 instructions being stored in memory.
4323 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
4325 * Makefile.in (maintainer-clean): Remove .log, core and *.core
4326 (From NetBSD) files.
4328 Wed May 29 22:57:40 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
4330 * ChangeLog.00, ChangeLog: ChangeLog from gdb-4.16 becomes
