39 open syscall to the numbers supported by the host.
41 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
43 * sim-endian.h: Don't have parameters on macro definitions which
44 are simply renaming functions, to permit use of XCONCAT2 in both
45 the macro name and the arguments in a use of such a definition.
47 2000-11-15 Jim Blandy <jimb@redhat.com>
49 * sim_calls.c: Doc fix.
50 (sim_fetch_register, sim_store_register): Call

85 1999-05-08 Felix Lee <flee@cygnus.com>
87 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
88 * configure: Regenerated to track ../common/aclocal.m4 changes.
90 1999-04-02 Keith Seitz <keiths@cygnus.com>
92 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
93 the frequency at which the poll_quit callback is called.

95 (sim_io_poll_quit): Only call the poll_quit callback
96 after the specified POLL_QUIT_INTERVAL.
98 1999-02-22 Jim Lemke <jlemke@cygnus.com>
100 * dc-complex: Force expansion on all bits of field BO.
101 Previously, the least-significant (prediction) bit was ignored.
102 * ppc-instructions (conditional branches): Implement mpc860c0 option.

108 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
110 Make the simulator compatible with the MPC750. It would be nicer
111 to make this a real multi-sim, but that's more work than we have
113 * emul_generic.c (emul_add_tree_options): Only require strict
114 alignment if it was explicitly requested at configuration time.
115 Don't make it the default for little-endian machines.
116 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
117 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
118 THRM2, THRM3): Plop in the MPC750 SPR registers.
119 (DABR): This is weird. This was HID5, but the PPC spec says this
120 should be DABR; why did some random processor use it for something
121 else? The HID5 entry dates back to the original checkin of the
122 simulator code in 1995, so remove it.
123 * sim_calls.c (register_names): Delete this; since the user can
124 now change GDB's list of register names dynamically, we can't
125 pretend there's a static mapping here.
126 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
127 function to get the register name. That ought to be accurate.
128 However, we're changing a compile-time dependency (using the
129 REGISTER_NAMES macro) into a link- and run-time dependency
130 (calling REGISTER_NAME, which happens to be a function call on the
133 1999-01-22 Jim Lemke <jlemke@cygnus.com>

160 fractional type, so that quiet NaN's aren't treated like
163 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
165 * table.c (table_open): For cygwin hosts, we need to use the
166 return value from the read routine as the number of bytes to
167 process. This apparently is due to text-mode vs binary-mode. If
168 the mounts are done text-mode, then the size returnedby fstat()
169 may be different than the number of bytes "read" in text mode.
171 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
173 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

185 return zero when nothing to do.
187 1998-06-26 Michael Meissner <meissner@cygnus.com>

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

568 or doubles clock interrupts.
571 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

603 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
605 * When performance monitoring is disabled, it is still possible to
606 determine the simulation speed by looking at the number of elapsed
607 ticks recorded by the event queue.
609 * psim.c (psim_write_register, psim_read_register): Force the cpu
610 to zero when it is either of `-1' or `nr_cpus'. In both cases the
611 next cpu would be zero any way.
613 * mon.c (mon_print_info): If possible, print the system cycle
614 performance. This is an indication of the number of instructions
617 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
619 * The code to allow an event queue to be updated during a signal
620 was missing. For main.c, a cntrl-c simulation termination wasn't
623 * The simulation would not correctly restart if an event requested
624 that the simulation be halted.

627 include a level vis -i2.
628 (psim_usage): Document.

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

743 * The code that put values in and extracted values from the cache
744 was too compilicated. The cache table did not allow values to be
745 computed from cache entries. #defines could only be used when a
746 cache was present, remove the restriction.
748 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
749 scratch variable is defined when a cache entry is beinf
750 filled. Change the definition of a COMPUTE variable to be defined
751 when the cache entry is being used.
752 * gen-icache.c: Update.
754 * ld-cache.h, ld-cache.c: Change field names so that their meaning

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

3223 * device.c (device_interrupt_ack) : Delete old
3225 * device_table.c (unimp_*) : Update to match
3227 * device_table.c (icu_io_write_buffer_callback) : Update to use
3229 * device_table.c (icu_interrupt_event_callback) : Ditto
3231 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3233 * device.c (external_to_device) : New function that provides a
3234 standard mapping between a devices internal representation (a
3235 pointer) and its external (or what is passed to a client)
3236 representation (a phandle). Implement using the cap object
3237 attached to the root node.
3239 * device.c (device_to_external) : Ditto
3240 * device.c (external_to_device_instance) : Ditto but for ihandle
3241 and device instance.
3242 * device.c (device_instance_to_external) : Ditto
3244 * Makefile (device.o): Add dependency on cap.
3246 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3247 needing to translate between internal and external representations
3248 changed to use the external_to_device et.al. device operations.
3249 * emul_chirp.c (chirp_emul_*) : Ditto
3251 * Makefile (emul_chirp.o): Remove dependency on cap
3253 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3255 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3256 on OpenBoot note section.
3258 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3260 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3261 read/write calls for buffer transfers. This will cause a fault to
3262 occure if the transfer fails. CHRP catches the fault while the
3263 others suffer the consequences.
3264 (emul_read_buffer): Ditto.
3265 (emul_write_word): Ditto.
3266 (emul_read_word): Ditto.
3267 (emul_read_string): Ditto.
3269 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3271 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3272 emul_generic (emul_blr_instruction): Use a real blr instruction to
3273 return from a client service call.
3275 * emul_chirp.c (services): Add all OpenBoot services to table.
3277 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3278 (emul_chirp_create) : Use names instead of numbers for
3279 instructions being stored in memory.
3281 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3283 * Makefile.in (maintainer-clean): Remove .log, core and *.core
