1063 open syscall to the numbers supported by the host.
1065 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
1067 * sim-endian.h: Don't have parameters on macro definitions which
1068 are simply renaming functions, to permit use of XCONCAT2 in both
1069 the macro name and the arguments in a use of such a definition.
1071 2000-11-15 Jim Blandy <jimb@redhat.com>
1073 * sim_calls.c: Doc fix.
1074 (sim_fetch_register, sim_store_register): Call
1075 gdbarch_register_name directly, instead of going through
1076 REGISTER_NAME macro.
1078 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1080 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1089 every time an event is removed from the queue.
1090 (update_time_from_event): Delete assertion that a negative
1091 time_from_event implies an empty event queue.
1093 Fri Apr 28 15:53:54 2000 Andrew Cagney <cagney@b1.cygnus.com>

1103 the exponent when denormalizing.
1105 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
1107 * configure: Regenerated to track ../common/aclocal.m4 changes.
1109 1999-05-08 Felix Lee <flee@cygnus.com>
1111 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1112 * configure: Regenerated to track ../common/aclocal.m4 changes.
1114 1999-04-02 Keith Seitz <keiths@cygnus.com>
1116 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
1117 the frequency at which the poll_quit callback is called.
1118 (poll_quit_count): New global.
1119 (sim_io_poll_quit): Only call the poll_quit callback
1120 after the specified POLL_QUIT_INTERVAL.
1122 1999-02-22 Jim Lemke <jlemke@cygnus.com>
1124 * dc-complex: Force expansion on all bits of field BO.
1125 Previously, the least-significant (prediction) bit was ignored.
1126 * ppc-instructions (conditional branches): Implement mpc860c0 option.
1127 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
1128 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
1129 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
1130 * interrupts.c (program_interrupt): Added handling for above interrupt.
1132 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1134 Make the simulator compatible with the MPC750. It would be nicer
1135 to make this a real multi-sim, but that's more work than we have
1137 * emul_generic.c (emul_add_tree_options): Only require strict
1138 alignment if it was explicitly requested at configuration time.
1139 Don't make it the default for little-endian machines.
1140 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1141 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1142 THRM2, THRM3): Plop in the MPC750 SPR registers.
1143 (DABR): This is weird. This was HID5, but the PPC spec says this
1144 should be DABR; why did some random processor use it for something
1145 else? The HID5 entry dates back to the original checkin of the
1146 simulator code in 1995, so remove it.
1147 * sim_calls.c (register_names): Delete this; since the user can
1148 now change GDB's list of register names dynamically, we can't
1149 pretend there's a static mapping here.
1150 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1151 function to get the register name. That ought to be accurate.
1152 However, we're changing a compile-time dependency (using the
1153 REGISTER_NAMES macro) into a link- and run-time dependency
1154 (calling REGISTER_NAME, which happens to be a function call on the
1157 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1159 * igen.c(gen_semantics_[ch]): setup/use of new option

1163 psim.c(is_num - added, psim_options): Parse and init new option.
1164 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

1183 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1184 fractional type, so that quiet NaN's aren't treated like
1187 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1189 * table.c (table_open): For cygwin hosts, we need to use the
1190 return value from the read routine as the number of bytes to
1191 process. This apparently is due to text-mode vs binary-mode. If
1192 the mounts are done text-mode, then the size returnedby fstat()
1193 may be different than the number of bytes "read" in text mode.
1195 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1197 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1214 * configure: Regenerate.
1215 * emul_{netbsd,unix}.c (toplevel): No longer try to include

1218 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1220 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1221 but there was no such target, only plain psim. So I changed the
1222 run target to depend on psim.
1224 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1226 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1227 now defined in ../common/aclocal.m4, and the double definition causes

1566 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1567 works for normal and boolean table entries.
1569 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1570 valid. Handle this just like *_{read,write}_register now handles

1589 shift + mask + test.
1591 * gen-idecode.c: Correct generated igen body so that it no drops
1592 or doubles clock interrupts.
1595 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1597 * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to

1627 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1629 * When performance monitoring is disabled, it is still possible to
1630 determine the simulation speed by looking at the number of elapsed
1631 ticks recorded by the event queue.
1633 * psim.c (psim_write_register, psim_read_register): Force the cpu
1634 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1635 next cpu would be zero any way.
1637 * mon.c (mon_print_info): If possible, print the system cycle
1638 performance. This is an indication of the number of instructions
1641 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1643 * The code to allow an event queue to be updated during a signal
1644 was missing. For main.c, a cntrl-c simulation termination wasn't
1647 * The simulation would not correctly restart if an event requested
1648 that the simulation be halted.
1650 * psim.c (psim_options): Add hack to -i option to optionally
1651 include a level vis -i2.
1652 (psim_usage): Document.

1671 * gen-idecode.c (print_run_until_stop_body): Call
1672 event_queue_process_events to clear possibly pending events before
1673 starting a simulation run. Re-arange main loop so that simulator
1674 is correctly restarted when an event halts the simulation.

1677 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1680 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1682 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

1700 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1701 to be initialized independant of the rest of the simulation
1702 initalization. Otherwize a trace option explictly set from gdb
1703 could be overridden by hw_trace.
1705 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1707 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1708 debug.c. It could be much simpler.
1710 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1750 the form <name>_is_<const> where it is a boolean field, generate
1751 the result of the expression instead of the expression its self.

1753 then generating corresponding definitions.
1755 * gen-icache.c (print_icache_struct): If there is no cache, do not
1756 output expressions in idecode.h file.
1758 * gen-icache.c (print_icache_body): Output them here.

1767 * The code that put values in and extracted values from the cache
1768 was too compilicated. The cache table did not allow values to be
1769 computed from cache entries. #defines could only be used when a
1770 cache was present, remove the restriction.
1772 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1773 scratch variable is defined when a cache entry is beinf
1774 filled. Change the definition of a COMPUTE variable to be defined
1775 when the cache entry is being used.
1776 * gen-icache.c: Update.
1778 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1791 * igen.c (main): Change 'R' option so that it does not force the
1794 * configure.in (enable-sim-icache): Clarify description. Make
1795 #define one of the defaults regardless of the cache. Probably
1796 should revamp and add a separate option.

4223 * device_table.c (console_io_read_buffer_callback): Adjust to
4224 handle biased address.
4225 * device_table.c (console_io_write_buffer_callback): Ditto
4227 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
4229 * device.c (attach_device_interrupt_edge): New. Interrupt model
4230 did not allow interrupts to be wired up as a general net (edges).
4231 Re-implement so that interrupt events can be passed to multiple
4232 controllers and interrupt controllers can further propogate
4235 * device.c (attach_device_interrupt_edge) : New, Ditto
4236 * device.c (detach_device_interrupt_edge) : New, Ditto

4242 * device.c (device_child_interrupt_detach) : New, Ditto
4244 * device.c (device_attach_interrupt) : Delete old
4245 * device.c (device_detach_interrupt) : Delete old
4246 * device.c (device_interrupt) : Delete old
4247 * device.c (device_interrupt_ack) : Delete old
4249 * device_table.c (unimp_*) : Update to match
4251 * device_table.c (icu_io_write_buffer_callback) : Update to use
4253 * device_table.c (icu_interrupt_event_callback) : Ditto
4255 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
4257 * device.c (external_to_device) : New function that provides a
4258 standard mapping between a devices internal representation (a
4259 pointer) and its external (or what is passed to a client)
4260 representation (a phandle). Implement using the cap object
4261 attached to the root node.
4263 * device.c (device_to_external) : Ditto
4264 * device.c (external_to_device_instance) : Ditto but for ihandle
4265 and device instance.
4266 * device.c (device_instance_to_external) : Ditto
4268 * Makefile (device.o): Add dependency on cap.
4270 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
4271 needing to translate between internal and external representations
4272 changed to use the external_to_device et.al. device operations.
4273 * emul_chirp.c (chirp_emul_*) : Ditto
4275 * Makefile (emul_chirp.o): Remove dependency on cap
4277 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
4279 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
4280 on OpenBoot note section.
4282 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
4284 * emul_generic.c (emul_write_buffer): Use vm faulting byte
4285 read/write calls for buffer transfers. This will cause a fault to
4286 occure if the transfer fails. CHRP catches the fault while the
4287 others suffer the consequences.
4288 (emul_read_buffer): Ditto.
4289 (emul_write_word): Ditto.
4290 (emul_read_word): Ditto.
4291 (emul_read_string): Ditto.
4293 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
4295 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
4296 emul_generic (emul_blr_instruction): Use a real blr instruction to
4297 return from a client service call.
4299 * emul_chirp.c (services): Add all OpenBoot services to table.
4301 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
4302 (emul_chirp_create) : Use names instead of numbers for
4303 instructions being stored in memory.
4305 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
4307 * Makefile.in (maintainer-clean): Remove .log, core and *.core
4308 (From NetBSD) files.
