140 are simply renaming functions, to permit use of XCONCAT2 in both
141 the macro name and the arguments in a use of such a definition.
143 2000-11-15 Jim Blandy <jimb@redhat.com>
145 * sim_calls.c: Doc fix.
146 (sim_fetch_register, sim_store_register): Call

181 1999-05-08 Felix Lee <flee@cygnus.com>
183 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
184 * configure: Regenerated to track ../common/aclocal.m4 changes.
186 1999-04-02 Keith Seitz <keiths@cygnus.com>

204 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
206 Make the simulator compatible with the MPC750. It would be nicer
207 to make this a real multi-sim, but that's more work than we have
209 * emul_generic.c (emul_add_tree_options): Only require strict
210 alignment if it was explicitly requested at configuration time.
211 Don't make it the default for little-endian machines.
212 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
213 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
214 THRM2, THRM3): Plop in the MPC750 SPR registers.
215 (DABR): This is weird. This was HID5, but the PPC spec says this
216 should be DABR; why did some random processor use it for something
217 else? The HID5 entry dates back to the original checkin of the
218 simulator code in 1995, so remove it.
219 * sim_calls.c (register_names): Delete this; since the user can
220 now change GDB's list of register names dynamically, we can't
221 pretend there's a static mapping here.
222 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
223 function to get the register name. That ought to be accurate.
224 However, we're changing a compile-time dependency (using the
225 REGISTER_NAMES macro) into a link- and run-time dependency
226 (calling REGISTER_NAME, which happens to be a function call on the
229 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

281 return zero when nothing to do.
283 1998-06-26 Michael Meissner <meissner@cygnus.com>
285 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
286 * configure: Regenerate.
287 * emul_{netbsd,unix}.c (toplevel): No longer try to include
288 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
290 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
292 * Makefile.in: The run target depended on a target psim$(EXEEXT),
293 but there was no such target, only plain psim. So I changed the
294 run target to depend on psim.
296 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
298 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
299 now defined in ../common/aclocal.m4, and the double definition causes
300 problems with AC_SUBST of EXEEXT.

701 * When performance monitoring is disabled, it is still possible to
702 determine the simulation speed by looking at the number of elapsed
703 ticks recorded by the event queue.
705 * psim.c (psim_write_register, psim_read_register): Force the cpu
706 to zero when it is either of `-1' or `nr_cpus'. In both cases the
707 next cpu would be zero any way.
709 * mon.c (mon_print_info): If possible, print the system cycle
710 performance. This is an indication of the number of instructions
713 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
715 * The code to allow an event queue to be updated during a signal
716 was missing. For main.c, a cntrl-c simulation termination wasn't

772 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
773 to be initialized independant of the rest of the simulation
774 initalization. Otherwize a trace option explictly set from gdb
775 could be overridden by hw_trace.
777 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
779 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
780 debug.c. It could be much simpler.
782 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
784 * Some devices support removable media. Add hooks to the disk

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

839 * The code that put values in and extracted values from the cache
840 was too compilicated. The cache table did not allow values to be
841 computed from cache entries. #defines could only be used when a
842 cache was present, remove the restriction.
844 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
845 scratch variable is defined when a cache entry is beinf
846 filled. Change the definition of a COMPUTE variable to be defined
847 when the cache entry is being used.
848 * gen-icache.c: Update.
850 * ld-cache.h, ld-cache.c: Change field names so that their meaning
851 is more obvious. old_name->field_name, new_name->derived_name.

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

3233 * psim.c(psim_options): Parse the psim options, installing their
3234 value in the device tree. Options are now first entered into a
3235 device tree and then extracted out again when needed. This allows
3236 greater flexability in configuration.
3238 * psim.c (psim_tree): Returns a basic device tree ready for
3239 parsing by psim_options.
3240 * psim.c (psim_usage): New. Give usage to varing levels of detail

3261 things. Extract all information from the device tree.
3263 * device_tree.c (trace_*): New device node, its properties are
3264 used to set the value of the trace options. Init this device (in
3265 psim_options) when ever the options are updated.

3269 * debug.h: Add trace_print_info, trace_print_device_tree and
3270 trace_dump_device_tree. The first is a replacement for the
3271 variable `print_info' found in main.c and sim_calls.c. The latter
3272 two enable the dumping of the entire device tree.
3274 * debug.c: Add to trace_description table.
3276 * main.c (main): Use above trace instead of local variable
3277 * sim_calls.c (sim_close): Ditto

3288 * corefile-n.h (core_map_read_N): When mapping from an address to
3289 a device, do not subtract the devices base. The device its self
3290 can do this. Brings the behavour into line with OpenBoot.
3291 * corefile-n.h (core_map_write_N): Ditto
3292 * corefile.c (core_map_read_buffer): Ditto
3293 * corefile.c (core_map_write_buffer): Ditto
3295 * device_table.c (console_io_read_buffer_callback): Adjust to
3296 handle biased address.
3297 * device_table.c (console_io_write_buffer_callback): Ditto
3299 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3301 * device.c (attach_device_interrupt_edge): New. Interrupt model
3302 did not allow interrupts to be wired up as a general net (edges).
3303 Re-implement so that interrupt events can be passed to multiple
3304 controllers and interrupt controllers can further propogate
3307 * device.c (attach_device_interrupt_edge) : New, Ditto

3327 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3329 * device.c (external_to_device) : New function that provides a
3330 standard mapping between a devices internal representation (a
3331 pointer) and its external (or what is passed to a client)
3332 representation (a phandle). Implement using the cap object
3333 attached to the root node.
3335 * device.c (device_to_external) : Ditto
3336 * device.c (external_to_device_instance) : Ditto but for ihandle
3337 and device instance.

3356 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3357 read/write calls for buffer transfers. This will cause a fault to
3358 occure if the transfer fails. CHRP catches the fault while the
3359 others suffer the consequences.
3360 (emul_read_buffer): Ditto.
3361 (emul_write_word): Ditto.
3362 (emul_read_word): Ditto.
