624 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
626 * sim-endian.h: Don't have parameters on macro definitions which
627 are simply renaming functions, to permit use of XCONCAT2 in both
628 the macro name and the arguments in a use of such a definition.
630 2000-11-15 Jim Blandy <jimb@redhat.com>
632 * sim_calls.c: Doc fix.
633 (sim_fetch_register, sim_store_register): Call

668 1999-05-08 Felix Lee <flee@cygnus.com>
670 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
671 * configure: Regenerated to track ../common/aclocal.m4 changes.
673 1999-04-02 Keith Seitz <keiths@cygnus.com>

691 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
693 Make the simulator compatible with the MPC750. It would be nicer
694 to make this a real multi-sim, but that's more work than we have
696 * emul_generic.c (emul_add_tree_options): Only require strict
697 alignment if it was explicitly requested at configuration time.
698 Don't make it the default for little-endian machines.
699 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
700 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
701 THRM2, THRM3): Plop in the MPC750 SPR registers.
702 (DABR): This is weird. This was HID5, but the PPC spec says this
703 should be DABR; why did some random processor use it for something
704 else? The HID5 entry dates back to the original checkin of the
705 simulator code in 1995, so remove it.
706 * sim_calls.c (register_names): Delete this; since the user can
707 now change GDB's list of register names dynamically, we can't
708 pretend there's a static mapping here.
709 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
710 function to get the register name. That ought to be accurate.
711 However, we're changing a compile-time dependency (using the
712 REGISTER_NAMES macro) into a link- and run-time dependency
713 (calling REGISTER_NAME, which happens to be a function call on the
716 1999-01-22 Jim Lemke <jlemke@cygnus.com>

723 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
725 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

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

768 return zero when nothing to do.
770 1998-06-26 Michael Meissner <meissner@cygnus.com>
772 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
773 * configure: Regenerate.
774 * emul_{netbsd,unix}.c (toplevel): No longer try to include
775 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
777 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
779 * Makefile.in: The run target depended on a target psim$(EXEEXT),
780 but there was no such target, only plain psim. So I changed the
781 run target to depend on psim.
783 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
785 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
786 now defined in ../common/aclocal.m4, and the double definition causes
787 problems with AC_SUBST of EXEEXT.

880 Tue Sep 9 22:13:23 1997 Felix Lee <flee@cygnus.com>
882 * basics.h (CONCAT*): token-pasting macros, if ALMOST_STDC,
884 * words.h: __int64 instead of long long for MSVC.

1125 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1126 works for normal and boolean table entries.
1128 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1189 determine the simulation speed by looking at the number of elapsed
1190 ticks recorded by the event queue.
1192 * psim.c (psim_write_register, psim_read_register): Force the cpu
1193 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1194 next cpu would be zero any way.
1196 * mon.c (mon_print_info): If possible, print the system cycle
1197 performance. This is an indication of the number of instructions
1200 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1202 * The code to allow an event queue to be updated during a signal
1203 was missing. For main.c, a cntrl-c simulation termination wasn't
1206 * The simulation would not correctly restart if an event requested
1207 that the simulation be halted.
1209 * psim.c (psim_options): Add hack to -i option to optionally
1210 include a level vis -i2.
1211 (psim_usage): Document.

1230 * gen-idecode.c (print_run_until_stop_body): Call
1231 event_queue_process_events to clear possibly pending events before
1232 starting a simulation run. Re-arange main loop so that simulator
1233 is correctly restarted when an event halts the simulation.

1259 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1260 to be initialized independant of the rest of the simulation
1261 initalization. Otherwize a trace option explictly set from gdb
1262 could be overridden by hw_trace.
1264 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1266 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1267 debug.c. It could be much simpler.
1269 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1309 the form <name>_is_<const> where it is a boolean field, generate
1310 the result of the expression instead of the expression its self.

1312 then generating corresponding definitions.
1314 * gen-icache.c (print_icache_struct): If there is no cache, do not
1315 output expressions in idecode.h file.
1317 * gen-icache.c (print_icache_body): Output them here.

1326 * The code that put values in and extracted values from the cache
1327 was too compilicated. The cache table did not allow values to be
1328 computed from cache entries. #defines could only be used when a
1329 cache was present, remove the restriction.
1331 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1332 scratch variable is defined when a cache entry is beinf
1333 filled. Change the definition of a COMPUTE variable to be defined
1334 when the cache entry is being used.
1335 * gen-icache.c: Update.
1337 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1350 * igen.c (main): Change 'R' option so that it does not force the
1353 * configure.in (enable-sim-icache): Clarify description. Make
1354 #define one of the defaults regardless of the cache. Probably
1355 should revamp and add a separate option.

3720 * psim.c(psim_options): Parse the psim options, installing their
3721 value in the device tree. Options are now first entered into a
3722 device tree and then extracted out again when needed. This allows
3723 greater flexability in configuration.

3748 things. Extract all information from the device tree.
3750 * device_tree.c (trace_*): New device node, its properties are
3751 used to set the value of the trace options. Init this device (in
3752 psim_options) when ever the options are updated.

3756 * debug.h: Add trace_print_info, trace_print_device_tree and
3757 trace_dump_device_tree. The first is a replacement for the
3758 variable `print_info' found in main.c and sim_calls.c. The latter
3759 two enable the dumping of the entire device tree.
3761 * debug.c: Add to trace_description table.
3763 * main.c (main): Use above trace instead of local variable
3764 * sim_calls.c (sim_close): Ditto

3775 * corefile-n.h (core_map_read_N): When mapping from an address to
3776 a device, do not subtract the devices base. The device its self
3777 can do this. Brings the behavour into line with OpenBoot.
3778 * corefile-n.h (core_map_write_N): Ditto
3779 * corefile.c (core_map_read_buffer): Ditto
3780 * corefile.c (core_map_write_buffer): Ditto
3782 * device_table.c (console_io_read_buffer_callback): Adjust to
3783 handle biased address.
3784 * device_table.c (console_io_write_buffer_callback): Ditto
3786 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3788 * device.c (attach_device_interrupt_edge): New. Interrupt model
3789 did not allow interrupts to be wired up as a general net (edges).
3790 Re-implement so that interrupt events can be passed to multiple
3791 controllers and interrupt controllers can further propogate

3814 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3816 * device.c (external_to_device) : New function that provides a
3817 standard mapping between a devices internal representation (a
3818 pointer) and its external (or what is passed to a client)
3819 representation (a phandle). Implement using the cap object
3820 attached to the root node.
3822 * device.c (device_to_external) : Ditto
3823 * device.c (external_to_device_instance) : Ditto but for ihandle
3824 and device instance.

3843 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3844 read/write calls for buffer transfers. This will cause a fault to
3845 occure if the transfer fails. CHRP catches the fault while the
3846 others suffer the consequences.
