187 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
189 * sim-endian.h: Don't have parameters on macro definitions which
190 are simply renaming functions, to permit use of XCONCAT2 in both
191 the macro name and the arguments in a use of such a definition.
193 2000-11-15 Jim Blandy <jimb@redhat.com>
195 * sim_calls.c: Doc fix.
196 (sim_fetch_register, sim_store_register): Call

231 1999-05-08 Felix Lee <flee@cygnus.com>
233 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
234 * configure: Regenerated to track ../common/aclocal.m4 changes.
236 1999-04-02 Keith Seitz <keiths@cygnus.com>

254 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
256 Make the simulator compatible with the MPC750. It would be nicer
257 to make this a real multi-sim, but that's more work than we have
259 * emul_generic.c (emul_add_tree_options): Only require strict
260 alignment if it was explicitly requested at configuration time.
261 Don't make it the default for little-endian machines.
262 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
263 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
264 THRM2, THRM3): Plop in the MPC750 SPR registers.
265 (DABR): This is weird. This was HID5, but the PPC spec says this
266 should be DABR; why did some random processor use it for something
267 else? The HID5 entry dates back to the original checkin of the
268 simulator code in 1995, so remove it.
269 * sim_calls.c (register_names): Delete this; since the user can
270 now change GDB's list of register names dynamically, we can't
271 pretend there's a static mapping here.
272 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
273 function to get the register name. That ought to be accurate.
274 However, we're changing a compile-time dependency (using the
275 REGISTER_NAMES macro) into a link- and run-time dependency
276 (calling REGISTER_NAME, which happens to be a function call on the
279 1999-01-22 Jim Lemke <jlemke@cygnus.com>
281 * igen.c(gen_semantics_[ch]): setup/use of new option

285 psim.c(is_num - added, psim_options): Parse and init new option.
286 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
288 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
290 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

301 poll the external environment.
303 1998-11-19 Michael Meissner <meissner@cygnus.com>
305 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
306 fractional type, so that quiet NaN's aren't treated like
309 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
311 * table.c (table_open): For cygwin hosts, we need to use the
312 return value from the read routine as the number of bytes to
313 process. This apparently is due to text-mode vs binary-mode. If
314 the mounts are done text-mode, then the size returnedby fstat()
315 may be different than the number of bytes "read" in text mode.
317 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
319 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

330 * sim_calls.c (sim_fetch_register, sim_store_register):
331 return zero when nothing to do.
333 1998-06-26 Michael Meissner <meissner@cygnus.com>
335 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
336 * configure: Regenerate.
337 * emul_{netbsd,unix}.c (toplevel): No longer try to include
338 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
340 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
342 * Makefile.in: The run target depended on a target psim$(EXEEXT),
343 but there was no such target, only plain psim. So I changed the
344 run target to depend on psim.
346 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
348 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
349 now defined in ../common/aclocal.m4, and the double definition causes
350 problems with AC_SUBST of EXEEXT.

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

668 * Property create/initialization still wasn't correctly ordered.
669 Should be delaying everything related to ihandle creation until
670 after the rest of the tree has been established.
672 * device.c (device_find_ihandle_runtime_property): Update.
673 (device_add_ihandle_runtime_property): Update.

749 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
751 * When performance monitoring is disabled, it is still possible to
752 determine the simulation speed by looking at the number of elapsed
753 ticks recorded by the event queue.
755 * psim.c (psim_write_register, psim_read_register): Force the cpu
756 to zero when it is either of `-1' or `nr_cpus'. In both cases the
757 next cpu would be zero any way.
759 * mon.c (mon_print_info): If possible, print the system cycle
760 performance. This is an indication of the number of instructions
763 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
765 * The code to allow an event queue to be updated during a signal
766 was missing. For main.c, a cntrl-c simulation termination wasn't
769 * The simulation would not correctly restart if an event requested
770 that the simulation be halted.
772 * psim.c (psim_options): Add hack to -i option to optionally
773 include a level vis -i2.
774 (psim_usage): Document.

788 (event_queue_init): Start the event queue out with processing
790 (event_queue_tick): Check that processing isn't still being
793 * gen-idecode.c (print_run_until_stop_body): Call
794 event_queue_process_events to clear possibly pending events before

810 here. Update to new format.

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

848 string array - use the first entry for the initial file image.
850 * tree.c (print_string_aray_property): New function - print a

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

875 then generating corresponding definitions.
877 * gen-icache.c (print_icache_struct): If there is no cache, do not

887 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
889 * The code that put values in and extracted values from the cache
890 was too compilicated. The cache table did not allow values to be
891 computed from cache entries. #defines could only be used when a
892 cache was present, remove the restriction.
894 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
895 scratch variable is defined when a cache entry is beinf
896 filled. Change the definition of a COMPUTE variable to be defined
897 when the cache entry is being used.
898 * gen-icache.c: Update.
900 * ld-cache.h, ld-cache.c: Change field names so that their meaning
901 is more obvious. old_name->field_name, new_name->derived_name.
902 * gen-icache.c: Update
904 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
905 different types of cache code - put into cache, extract from

907 * gen-icache.c (print_icache_extraction): Ditto.
909 * gen-semantics.c (print_c_semantic): Update use.
910 * gen-idecode.c (print_jump_insn): Update use.

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

922 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

2230 always update the cache_entries semantic and address fields.
2232 * gen-idecode.c (print_idecode_switch_illegal): Include a break

2234 which is a hangover from looking a at switch statements generated

2286 option directly into the device tree. Was using atol() which is
2287 dangerously non portable.
2289 Mon Jul 22 22:17:08 1996 Andrew Cagney <cagney@highland.com.au>
2291 * configure.in (icache): Extend icache flag to include an insn

2330 * psim.c (run_until_stop): Delete the old run_until_stop function

2389 * igen.c: Add option (-C) to generate semantics in the instruction
2392 * configure.in (--enable-sim-icache): Accept an option list such
2393 as 1024,define. Add a new choice to the list - semantic - which

2399 * configure.in: New option --enable-sim-line-nr (default enabled).

2455 * configure.in: Adjust filter flag so that default includes 32bit
