32 open syscall to the numbers supported by the host.
34 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
36 * sim-endian.h: Don't have parameters on macro definitions which
37 are simply renaming functions, to permit use of XCONCAT2 in both
38 the macro name and the arguments in a use of such a definition.
40 2000-11-15 Jim Blandy <jimb@redhat.com>
42 * sim_calls.c: Doc fix.
43 (sim_fetch_register, sim_store_register): Call

72 the exponent when denormalizing.
74 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
76 * configure: Regenerated to track ../common/aclocal.m4 changes.
78 1999-05-08 Felix Lee <flee@cygnus.com>
80 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
81 * configure: Regenerated to track ../common/aclocal.m4 changes.
83 1999-04-02 Keith Seitz <keiths@cygnus.com>
85 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
86 the frequency at which the poll_quit callback is called.
87 (poll_quit_count): New global.
88 (sim_io_poll_quit): Only call the poll_quit callback
89 after the specified POLL_QUIT_INTERVAL.
91 1999-02-22 Jim Lemke <jlemke@cygnus.com>
93 * dc-complex: Force expansion on all bits of field BO.
94 Previously, the least-significant (prediction) bit was ignored.
95 * ppc-instructions (conditional branches): Implement mpc860c0 option.

101 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
103 Make the simulator compatible with the MPC750. It would be nicer
104 to make this a real multi-sim, but that's more work than we have
106 * emul_generic.c (emul_add_tree_options): Only require strict
107 alignment if it was explicitly requested at configuration time.
108 Don't make it the default for little-endian machines.
109 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
110 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
111 THRM2, THRM3): Plop in the MPC750 SPR registers.
112 (DABR): This is weird. This was HID5, but the PPC spec says this
113 should be DABR; why did some random processor use it for something
114 else? The HID5 entry dates back to the original checkin of the
115 simulator code in 1995, so remove it.
116 * sim_calls.c (register_names): Delete this; since the user can
117 now change GDB's list of register names dynamically, we can't
118 pretend there's a static mapping here.
119 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
120 function to get the register name. That ought to be accurate.
121 However, we're changing a compile-time dependency (using the
122 REGISTER_NAMES macro) into a link- and run-time dependency
123 (calling REGISTER_NAME, which happens to be a function call on the
126 1999-01-22 Jim Lemke <jlemke@cygnus.com>

132 psim.c(is_num - added, psim_options): Parse and init new option.
133 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
135 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

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

178 return zero when nothing to do.
180 1998-06-26 Michael Meissner <meissner@cygnus.com>

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

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

669 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
670 to be initialized independant of the rest of the simulation

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

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

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

3220 * device_table.c (icu_io_write_buffer_callback) : Update to use
3222 * device_table.c (icu_interrupt_event_callback) : Ditto
3224 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3226 * device.c (external_to_device) : New function that provides a
3227 standard mapping between a devices internal representation (a
3228 pointer) and its external (or what is passed to a client)
3229 representation (a phandle). Implement using the cap object
3230 attached to the root node.
3232 * device.c (device_to_external) : Ditto
3233 * device.c (external_to_device_instance) : Ditto but for ihandle
3234 and device instance.
3235 * device.c (device_instance_to_external) : Ditto
3237 * Makefile (device.o): Add dependency on cap.
3239 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3240 needing to translate between internal and external representations
3241 changed to use the external_to_device et.al. device operations.
3242 * emul_chirp.c (chirp_emul_*) : Ditto
3244 * Makefile (emul_chirp.o): Remove dependency on cap
3246 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3248 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3249 on OpenBoot note section.
3251 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3253 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3254 read/write calls for buffer transfers. This will cause a fault to
3255 occure if the transfer fails. CHRP catches the fault while the
3256 others suffer the consequences.
3257 (emul_read_buffer): Ditto.
3258 (emul_write_word): Ditto.
3259 (emul_read_word): Ditto.
3260 (emul_read_string): Ditto.
3262 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3264 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3265 emul_generic (emul_blr_instruction): Use a real blr instruction to
3266 return from a client service call.
3268 * emul_chirp.c (services): Add all OpenBoot services to table.
3270 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3271 (emul_chirp_create) : Use names instead of numbers for
3272 instructions being stored in memory.
3274 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3276 * Makefile.in (maintainer-clean): Remove .log, core and *.core
