22 * emul_netbsd.c (do_open): Translate the flag parameter to the
23 open syscall to the numbers supported by the host.
25 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
27 * sim-endian.h: Don't have parameters on macro definitions which
28 are simply renaming functions, to permit use of XCONCAT2 in both
29 the macro name and the arguments in a use of such a definition.
31 2000-11-15 Jim Blandy <jimb@redhat.com>
33 * sim_calls.c: Doc fix.
34 (sim_fetch_register, sim_store_register): Call

49 every time an event is removed from the queue.
50 (update_time_from_event): Delete assertion that a negative
51 time_from_event implies an empty event queue.

60 2000-03-25 Geoff Keating <geoffk@cygnus.com>
62 * ppc-instructions (Disabled_Exponent_Underflow): Increment
63 the exponent when denormalizing.
65 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
67 * configure: Regenerated to track ../common/aclocal.m4 changes.
69 1999-05-08 Felix Lee <flee@cygnus.com>
71 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
72 * configure: Regenerated to track ../common/aclocal.m4 changes.
74 1999-04-02 Keith Seitz <keiths@cygnus.com>
76 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
77 the frequency at which the poll_quit callback is called.
78 (poll_quit_count): New global.
79 (sim_io_poll_quit): Only call the poll_quit callback
80 after the specified POLL_QUIT_INTERVAL.
82 1999-02-22 Jim Lemke <jlemke@cygnus.com>
84 * dc-complex: Force expansion on all bits of field BO.
85 Previously, the least-significant (prediction) bit was ignored.
86 * ppc-instructions (conditional branches): Implement mpc860c0 option.

92 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
94 Make the simulator compatible with the MPC750. It would be nicer
95 to make this a real multi-sim, but that's more work than we have
97 * emul_generic.c (emul_add_tree_options): Only require strict
98 alignment if it was explicitly requested at configuration time.
99 Don't make it the default for little-endian machines.
100 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
101 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
102 THRM2, THRM3): Plop in the MPC750 SPR registers.
103 (DABR): This is weird. This was HID5, but the PPC spec says this
104 should be DABR; why did some random processor use it for something
105 else? The HID5 entry dates back to the original checkin of the
106 simulator code in 1995, so remove it.
107 * sim_calls.c (register_names): Delete this; since the user can
108 now change GDB's list of register names dynamically, we can't
109 pretend there's a static mapping here.
110 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
111 function to get the register name. That ought to be accurate.
112 However, we're changing a compile-time dependency (using the
113 REGISTER_NAMES macro) into a link- and run-time dependency
114 (calling REGISTER_NAME, which happens to be a function call on the
117 1999-01-22 Jim Lemke <jlemke@cygnus.com>
119 * igen.c(gen_semantics_[ch]): setup/use of new option

123 psim.c(is_num - added, psim_options): Parse and init new option.
124 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
126 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
128 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

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

168 * sim_calls.c (sim_fetch_register, sim_store_register):
169 return zero when nothing to do.
171 1998-06-26 Michael Meissner <meissner@cygnus.com>
173 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
174 * configure: Regenerate.
175 * emul_{netbsd,unix}.c (toplevel): No longer try to include
176 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
178 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
180 * Makefile.in: The run target depended on a target psim$(EXEEXT),
181 but there was no such target, only plain psim. So I changed the
182 run target to depend on psim.
184 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
186 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
187 now defined in ../common/aclocal.m4, and the double definition causes
188 problems with AC_SUBST of EXEEXT.

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

665 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
667 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
668 debug.c. It could be much simpler.
670 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

727 * The code that put values in and extracted values from the cache
728 was too compilicated. The cache table did not allow values to be
729 computed from cache entries. #defines could only be used when a
730 cache was present, remove the restriction.
732 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
733 scratch variable is defined when a cache entry is beinf
734 filled. Change the definition of a COMPUTE variable to be defined
735 when the cache entry is being used.
736 * gen-icache.c: Update.
738 * ld-cache.h, ld-cache.c: Change field names so that their meaning

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

3220 representation (a phandle). Implement using the cap object
3221 attached to the root node.
3223 * device.c (device_to_external) : Ditto
3224 * device.c (external_to_device_instance) : Ditto but for ihandle
3225 and device instance.
3226 * device.c (device_instance_to_external) : Ditto
3228 * Makefile (device.o): Add dependency on cap.
3230 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3231 needing to translate between internal and external representations
3232 changed to use the external_to_device et.al. device operations.
3233 * emul_chirp.c (chirp_emul_*) : Ditto
3235 * Makefile (emul_chirp.o): Remove dependency on cap

3239 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3240 on OpenBoot note section.
3242 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3244 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3245 read/write calls for buffer transfers. This will cause a fault to
3246 occure if the transfer fails. CHRP catches the fault while the
3247 others suffer the consequences.
3248 (emul_read_buffer): Ditto.
3249 (emul_write_word): Ditto.
3250 (emul_read_word): Ditto.
3251 (emul_read_string): Ditto.
3253 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3255 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3256 emul_generic (emul_blr_instruction): Use a real blr instruction to
3257 return from a client service call.
3259 * emul_chirp.c (services): Add all OpenBoot services to table.
3261 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3262 (emul_chirp_create) : Use names instead of numbers for
3263 instructions being stored in memory.
3265 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3267 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3268 (From NetBSD) files.
