35
36 * sim-endian.h: Don't have parameters on macro definitions which

7a292a7a
SS		 831999-04-02 Keith Seitz <keiths@cygnus.com>
84
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.
90
911999-02-22 Jim Lemke <jlemke@cygnus.com>

SS		 1011999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
102
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
105 time for.
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
124 PPC).
125
1261999-01-22 Jim Lemke <jlemke@cygnus.com>
127
128 * igen.c(gen_semantics_[ch]): setup/use of new option
129 (-o mpc860c0[=n]).
130 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
131 ppc-instructions(the four branch insn groups): detect problematic br's.
132 psim.c(is_num - added, psim_options): Parse and init new option.
133 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
134
1351998-12-01 Ken Raeburn <raeburn@cygnus.com>
136
137 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.
138
139Fri Nov 20 12:17:28 1998 Andrew Cagney <cagney@b1.cygnus.com>
140
141 * main.c (sim_io_poll_quit): Stub function.
142
143 * events.c (SIM_EVENTS_POLL_RATE): Define.
144 (sim_events_poll): Copy function from common/sim-events.c.
145 (event_queue_init): Copy scheduling of sim_events_poll from same.
146
147 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
148 poll the external environment.
149
1501998-11-19 Michael Meissner <meissner@cygnus.com>
151
152 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
153 fractional type, so that quiet NaN's aren't treated like
154 Infinities.
155
156Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
157
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.
163
164Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
165
166 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

183 * configure: Regenerate.
184 * emul_{netbsd,unix}.c (toplevel): No longer try to include

186
187Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
188
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.
192
193Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
194
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.

553 max iterations exceeded.
554
555 * gen-idecode.c: Re-work the table lookup code so that it assumes
556 that the entry is a leaf by default. Simplify the boolean table
557 entry code so that it involves a mask + test instead of shift +
558 shift + mask + test.
559
560 * gen-idecode.c: Correct generated igen body so that it no drops
561 or doubles clock interrupts.
562

597
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.
601
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.
605
606 * mon.c (mon_print_info): If possible, print the system cycle
607 performance. This is an indication of the number of instructions
608 per second.
609
610Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
611
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
614 handled cleanly.
615
616 * The simulation would not correctly restart if an event requested
617 that the simulation be halted.
618
619 * psim.c (psim_options): Add hack to -i option to optionally
620 include a level vis -i2.
621 (psim_usage): Document.
622

634 so that it is tolerant of halts.
635 (event_queue_init): Start the event queue out with processing
636 false.
637 (event_queue_tick): Check that processing isn't still being
638 performed.

650
651 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
652 RA. Based on instruction frequency stats, expand additional
653 instructions.
654 * ppc-instructions: Change all `RA == 0' to RA_is_0.
655
656 * ppc-opcode-stupid: Move all but the basic table in -complex into
657 here. Update to new format.
658
659 * Makefile.in (tmp-defines): New target. Force defines.h to always

661
662Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
663

665 Implement.
666
667Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
668
669 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
670 to be initialized independant of the rest of the simulation
671 initalization. Otherwize a trace option explictly set from gdb
672 could be overridden by hw_trace.
673
674 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
675
676 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
677 debug.c. It could be much simpler.
678
679Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
680
681 * Some devices support removable media. Add hooks to the disk

712
713 * For expressions like (RA == 0) that are entered in to the cache
714 as RA_is_0. If possible generate the result of the expression so
715 that the compiler gets a better chance of eliminating dead
716 branches.
717
718 * gen-icache.c (print_icache_extraction): For a cache entry of
719 the form <name>_is_<const> where it is a boolean field, generate
720 the result of the expression instead of the expression its self.
721 (print_icache_body): Remove code that was looking for *_is_0 and
722 then generating corresponding definitions.
723
724 * gen-icache.c (print_icache_struct): If there is no cache, do not
725 output expressions in idecode.h file.
726
727 * gen-icache.c (print_icache_body): Output them here.
728

732 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
733
734Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
735
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.
740
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

755
756 * gen-semantics.c (print_c_semantic): Update use.
757 * gen-idecode.c (print_jump_insn): Update use.
758 * gen-icache.c (print_icache_function): Update use.
759
760 * igen.c (main): Change 'R' option so that it does not force the
761 cache.
762
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.
766

778
779 * The cap object was retaining a reference to the instance of a
780 device after it was deleted. Instead add and remove cap's from the
781 cap db as they are created and deleted. This ensuring that a
782 capibility is only used during the lifetime of the corresponding
783 object.
784
785 * cap.h, cap.c: Correct cap type - was signed32 should be
786 signed_cell.
787
788 * cap.c (cap_add, cap_remove): New methods for cap object that
789 allow the explicit addition and removal of internal objects that
790 the cap knows about.
791
792 * cap.c (cap_init): Rewrite. Verify that the only objects
793 remaining in the cap data base are those that were entered first.
794 Thse objects will be the permenant ones.

817
818 * The memory "claim" and "release" methods take an address and
819 size as arguments. These may be multi cell values. Initially fix
820 the memory code so that they check/detect this. Leave the

822
823 * hw_memory.c (hw_memory_instance_claim,
824 hw_memory_instance_release): Handle multi-cell memory devices.

2077 always update the cache_entries semantic and address fields.
2078
2079 * gen-idecode.c (print_idecode_switch_illegal): Include a break

2095 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2096 same as cpu.[hc].
2097
2098 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2099 name for a lable and then branch to it.
2100
2101 * ppc-instructions (convert_to_integer, Floating Round to
2102 Single-Precision, Floating Convert from Integer Doubleword): Use
2103 LABEL and GOTO instead of the recently added switch statements.

2129
2130Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>

2173
2174 * std-config.h: Change psim.c so that it isn't inlined (as this is
2175 no longer needed).
2176
2177 * psim.c (run_until_stop): Delete the old run_until_stop function
2178 instead calling the idecode_run and idecode_run_until_stop
2179 functions that gen-idecode.c is now creating.

2229 testing jumping idecodes.
2230

2245
2246 * configure.in: New option --enable-sim-line-nr (default enabled).

2261
2262 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2263 that they use the same technique as igen (ie a dummy targets
2264 tmp-pk and tmp-hw are created).
2265
2266Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2267
2268 * Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.

3176 * device.c (device_tree_print_device): New. Prints the device
3177 tree in a format that is consistent with what can be parsed by the
3178 device tree load from file code.
3179
3180 * psim.c (psim_create): Dump device tree if enabled. If nump
3181 selected, exit psim immediatly.

3184
3185 * corefile-n.h (core_map_read_N): When mapping from an address to
3186 a device, do not subtract the devices base. The device its self
3187 can do this. Brings the behavour into line with OpenBoot.
3188 * corefile-n.h (core_map_write_N): Ditto
3189 * corefile.c (core_map_read_buffer): Ditto
3190 * corefile.c (core_map_write_buffer): Ditto

3197
3198 * device.c (attach_device_interrupt_edge): New. Interrupt model
3199 did not allow interrupts to be wired up as a general net (edges).
3200 Re-implement so that interrupt events can be passed to multiple
3201 controllers and interrupt controllers can further propogate
3202 interrupt events.
3203
3204 * device.c (attach_device_interrupt_edge) : New, Ditto
3205 * device.c (detach_device_interrupt_edge) : New, Ditto

3223
3224Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3225
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.
3231
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
3236
3237 * Makefile (device.o): Add dependency on cap.
3238
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
3243
3244 * Makefile (emul_chirp.o): Remove dependency on cap

3249 on OpenBoot note section.
3250
3251Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3252
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.
