1075 * emul_netbsd.c (do_open): Translate the flag parameter to the
1076 open syscall to the numbers supported by the host.
1078 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
1080 * sim-endian.h: Don't have parameters on macro definitions which
1081 are simply renaming functions, to permit use of XCONCAT2 in both
1082 the macro name and the arguments in a use of such a definition.
1084 2000-11-15 Jim Blandy <jimb@redhat.com>
1086 * sim_calls.c: Doc fix.
1087 (sim_fetch_register, sim_store_register): Call
1088 gdbarch_register_name directly, instead of going through
1089 REGISTER_NAME macro.
1091 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1093 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1102 every time an event is removed from the queue.
1103 (update_time_from_event): Delete assertion that a negative

1116 the exponent when denormalizing.
1118 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
1120 * configure: Regenerated to track ../common/aclocal.m4 changes.
1122 1999-05-08 Felix Lee <flee@cygnus.com>
1124 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1125 * configure: Regenerated to track ../common/aclocal.m4 changes.
1127 1999-04-02 Keith Seitz <keiths@cygnus.com>
1129 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
1130 the frequency at which the poll_quit callback is called.
1131 (poll_quit_count): New global.
1132 (sim_io_poll_quit): Only call the poll_quit callback
1133 after the specified POLL_QUIT_INTERVAL.
1135 1999-02-22 Jim Lemke <jlemke@cygnus.com>
1137 * dc-complex: Force expansion on all bits of field BO.
1138 Previously, the least-significant (prediction) bit was ignored.
1139 * ppc-instructions (conditional branches): Implement mpc860c0 option.
1140 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
1141 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
1142 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
1143 * interrupts.c (program_interrupt): Added handling for above interrupt.
1145 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1147 Make the simulator compatible with the MPC750. It would be nicer
1148 to make this a real multi-sim, but that's more work than we have
1150 * emul_generic.c (emul_add_tree_options): Only require strict
1151 alignment if it was explicitly requested at configuration time.
1152 Don't make it the default for little-endian machines.
1153 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1154 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1155 THRM2, THRM3): Plop in the MPC750 SPR registers.
1156 (DABR): This is weird. This was HID5, but the PPC spec says this
1157 should be DABR; why did some random processor use it for something
1158 else? The HID5 entry dates back to the original checkin of the
1159 simulator code in 1995, so remove it.
1160 * sim_calls.c (register_names): Delete this; since the user can
1161 now change GDB's list of register names dynamically, we can't
1162 pretend there's a static mapping here.
1163 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1164 function to get the register name. That ought to be accurate.
1165 However, we're changing a compile-time dependency (using the
1166 REGISTER_NAMES macro) into a link- and run-time dependency
1167 (calling REGISTER_NAME, which happens to be a function call on the
1170 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1172 * igen.c(gen_semantics_[ch]): setup/use of new option

1196 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1197 fractional type, so that quiet NaN's aren't treated like
1200 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1202 * table.c (table_open): For cygwin hosts, we need to use the
1203 return value from the read routine as the number of bytes to
1204 process. This apparently is due to text-mode vs binary-mode. If
1205 the mounts are done text-mode, then the size returnedby fstat()
1206 may be different than the number of bytes "read" in text mode.
1208 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1210 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1227 * configure: Regenerate.
1228 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1229 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1231 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1233 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1234 but there was no such target, only plain psim. So I changed the
1235 run target to depend on psim.
1237 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1239 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1240 now defined in ../common/aclocal.m4, and the double definition causes
1241 problems with AC_SUBST of EXEEXT.

1330 mask extracting shift amount. Correctly condition for setting XER
1332 (ldhau): From Johannes Reisinger, update rA after load.
1334 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>

1579 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1580 works for normal and boolean table entries.
1582 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1583 valid. Handle this just like *_{read,write}_register now handles

1604 * gen-idecode.c: Correct generated igen body so that it no drops
1605 or doubles clock interrupts.
1608 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1610 * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to

1643 determine the simulation speed by looking at the number of elapsed
1644 ticks recorded by the event queue.
1646 * psim.c (psim_write_register, psim_read_register): Force the cpu
1647 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1648 next cpu would be zero any way.
1650 * mon.c (mon_print_info): If possible, print the system cycle
1651 performance. This is an indication of the number of instructions
1654 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1656 * The code to allow an event queue to be updated during a signal
1657 was missing. For main.c, a cntrl-c simulation termination wasn't
1660 * The simulation would not correctly restart if an event requested
1661 that the simulation be halted.
1663 * psim.c (psim_options): Add hack to -i option to optionally
1664 include a level vis -i2.
1665 (psim_usage): Document.

1684 * gen-idecode.c (print_run_until_stop_body): Call
1685 event_queue_process_events to clear possibly pending events before

1713 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1714 to be initialized independant of the rest of the simulation
1715 initalization. Otherwize a trace option explictly set from gdb
1716 could be overridden by hw_trace.
1718 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1720 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1721 debug.c. It could be much simpler.

1763 the form <name>_is_<const> where it is a boolean field, generate
1764 the result of the expression instead of the expression its self.

1780 * The code that put values in and extracted values from the cache
1781 was too compilicated. The cache table did not allow values to be
1782 computed from cache entries. #defines could only be used when a
1783 cache was present, remove the restriction.
1785 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1786 scratch variable is defined when a cache entry is beinf
1787 filled. Change the definition of a COMPUTE variable to be defined
1788 when the cache entry is being used.
1789 * gen-icache.c: Update.
1791 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1804 * igen.c (main): Change 'R' option so that it does not force the
1807 * configure.in (enable-sim-icache): Clarify description. Make
1808 #define one of the defaults regardless of the cache. Probably
1809 should revamp and add a separate option.

4221 tree in a format that is consistent with what can be parsed by the
4222 device tree load from file code.
4224 * psim.c (psim_create): Dump device tree if enabled. If nump
4225 selected, exit psim immediately.
4227 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
4229 * corefile-n.h (core_map_read_N): When mapping from an address to
4230 a device, do not subtract the devices base. The device its self
4231 can do this. Brings the behavour into line with OpenBoot.
4232 * corefile-n.h (core_map_write_N): Ditto
4233 * corefile.c (core_map_read_buffer): Ditto
4234 * corefile.c (core_map_write_buffer): Ditto
4236 * device_table.c (console_io_read_buffer_callback): Adjust to
4237 handle biased address.
4238 * device_table.c (console_io_write_buffer_callback): Ditto
4240 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
4242 * device.c (attach_device_interrupt_edge): New. Interrupt model
4243 did not allow interrupts to be wired up as a general net (edges).
4244 Re-implement so that interrupt events can be passed to multiple
4245 controllers and interrupt controllers can further propogate
4248 * device.c (attach_device_interrupt_edge) : New, Ditto
4249 * device.c (detach_device_interrupt_edge) : New, Ditto
4250 * device.c (clean_device_interrupt_edges) : New, Ditto
4251 * device.c (device_interrupt_event) : New, Ditto
4252 * device.c (device_interrupt_attach) : New, Ditto
4253 * device.c (device_interrupt_detach) : New, Ditto
4254 * device.c (device_child_interrupt_attach) : New, Ditto
4255 * device.c (device_child_interrupt_detach) : New, Ditto
4257 * device.c (device_attach_interrupt) : Delete old
4258 * device.c (device_detach_interrupt) : Delete old
4259 * device.c (device_interrupt) : Delete old
4260 * device.c (device_interrupt_ack) : Delete old
4262 * device_table.c (unimp_*) : Update to match
4264 * device_table.c (icu_io_write_buffer_callback) : Update to use
4266 * device_table.c (icu_interrupt_event_callback) : Ditto
4268 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
4270 * device.c (external_to_device) : New function that provides a
4271 standard mapping between a devices internal representation (a
4272 pointer) and its external (or what is passed to a client)
4273 representation (a phandle). Implement using the cap object
4274 attached to the root node.
4276 * device.c (device_to_external) : Ditto
4277 * device.c (external_to_device_instance) : Ditto but for ihandle
4278 and device instance.
4279 * device.c (device_instance_to_external) : Ditto
4281 * Makefile (device.o): Add dependency on cap.
4283 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
4284 needing to translate between internal and external representations
4285 changed to use the external_to_device et.al. device operations.
4286 * emul_chirp.c (chirp_emul_*) : Ditto
4288 * Makefile (emul_chirp.o): Remove dependency on cap
4290 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
4292 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
4293 on OpenBoot note section.
4295 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
4297 * emul_generic.c (emul_write_buffer): Use vm faulting byte
4298 read/write calls for buffer transfers. This will cause a fault to
4299 occure if the transfer fails. CHRP catches the fault while the
4300 others suffer the consequences.
4301 (emul_read_buffer): Ditto.
4302 (emul_write_word): Ditto.
4303 (emul_read_word): Ditto.
4304 (emul_read_string): Ditto.
4306 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
4308 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
4309 emul_generic (emul_blr_instruction): Use a real blr instruction to
4310 return from a client service call.
4312 * emul_chirp.c (services): Add all OpenBoot services to table.
4314 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
4315 (emul_chirp_create) : Use names instead of numbers for
4316 instructions being stored in memory.
4318 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
4320 * Makefile.in (maintainer-clean): Remove .log, core and *.core
4321 (From NetBSD) files.
