GK		 162000-12-12 Geoffrey Keating <geoffk@redhat.com>
17
18 * sim-endian.h: Don't have parameters on macro definitions which

7a292a7a
SS		 651999-04-02 Keith Seitz <keiths@cygnus.com>
66
67 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
68 the frequency at which the poll_quit callback is called.
69 (poll_quit_count): New global.
70 (sim_io_poll_quit): Only call the poll_quit callback
71 after the specified POLL_QUIT_INTERVAL.
72
731999-02-22 Jim Lemke <jlemke@cygnus.com>
74

SS		 831999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
84
85 Make the simulator compatible with the MPC750. It would be nicer
86 to make this a real multi-sim, but that's more work than we have
87 time for.
88 * emul_generic.c (emul_add_tree_options): Only require strict
89 alignment if it was explicitly requested at configuration time.
90 Don't make it the default for little-endian machines.
91 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
92 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
93 THRM2, THRM3): Plop in the MPC750 SPR registers.
94 (DABR): This is weird. This was HID5, but the PPC spec says this
95 should be DABR; why did some random processor use it for something
96 else? The HID5 entry dates back to the original checkin of the
97 simulator code in 1995, so remove it.
98 * sim_calls.c (register_names): Delete this; since the user can
99 now change GDB's list of register names dynamically, we can't
100 pretend there's a static mapping here.
101 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
102 function to get the register name. That ought to be accurate.
103 However, we're changing a compile-time dependency (using the
104 REGISTER_NAMES macro) into a link- and run-time dependency
105 (calling REGISTER_NAME, which happens to be a function call on the
106 PPC).
107
1081999-01-22 Jim Lemke <jlemke@cygnus.com>
109
110 * igen.c(gen_semantics_[ch]): setup/use of new option
111 (-o mpc860c0[=n]).
112 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
113 ppc-instructions(the four branch insn groups): detect problematic br's.
114 psim.c(is_num - added, psim_options): Parse and init new option.
115 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
116
1171998-12-01 Ken Raeburn <raeburn@cygnus.com>
118
119 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.
120
121Fri Nov 20 12:17:28 1998 Andrew Cagney <cagney@b1.cygnus.com>
122
123 * main.c (sim_io_poll_quit): Stub function.
124
125 * events.c (SIM_EVENTS_POLL_RATE): Define.
126 (sim_events_poll): Copy function from common/sim-events.c.
127 (event_queue_init): Copy scheduling of sim_events_poll from same.
128
129 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
130 poll the external environment.
131
1321998-11-19 Michael Meissner <meissner@cygnus.com>
133
134 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
135 fractional type, so that quiet NaN's aren't treated like
136 Infinities.
137
138Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
139
140 * table.c (table_open): For cygwin hosts, we need to use the
141 return value from the read routine as the number of bytes to
142 process. This apparently is due to text-mode vs binary-mode. If
143 the mounts are done text-mode, then the size returnedby fstat()
144 may be different than the number of bytes "read" in text mode.
145
146Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
147
148 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

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

168
169Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
170
171 * Makefile.in: The run target depended on a target psim$(EXEEXT),
172 but there was no such target, only plain psim. So I changed the
173 run target to depend on psim.
174
175Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
176
177 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
178 now defined in ../common/aclocal.m4, and the double definition causes

499 after the rest of the tree has been established.
500
501 * device.c (device_find_ihandle_runtime_property): Update.
502 (device_add_ihandle_runtime_property): Update.

534 (psim_max_iterations_exceeded): New function, abort simulation if
535 max iterations exceeded.
536
537 * gen-idecode.c: Re-work the table lookup code so that it assumes
538 that the entry is a leaf by default. Simplify the boolean table
539 entry code so that it involves a mask + test instead of shift +
540 shift + mask + test.
541
542 * gen-idecode.c: Correct generated igen body so that it no drops
543 or doubles clock interrupts.
544
545

578Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
579
580 * When performance monitoring is disabled, it is still possible to
581 determine the simulation speed by looking at the number of elapsed
582 ticks recorded by the event queue.
583
584 * psim.c (psim_write_register, psim_read_register): Force the cpu
585 to zero when it is either of `-1' or `nr_cpus'. In both cases the
586 next cpu would be zero any way.
587
588 * mon.c (mon_print_info): If possible, print the system cycle
589 performance. This is an indication of the number of instructions
590 per second.
591
592Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
593
594 * The code to allow an event queue to be updated during a signal
595 was missing. For main.c, a cntrl-c simulation termination wasn't
596 handled cleanly.
597
598 * The simulation would not correctly restart if an event requested
599 that the simulation be halted.
600
601 * psim.c (psim_options): Add hack to -i option to optionally
602 include a level vis -i2.
603 (psim_usage): Document.
604

615 the processing state when processing has started. Adjust code
616 so that it is tolerant of halts.
617 (event_queue_init): Start the event queue out with processing
618 false.
619 (event_queue_tick): Check that processing isn't still being
620 performed.
621
622 * gen-idecode.c (print_run_until_stop_body): Call
623 event_queue_process_events to clear possibly pending events before
624 starting a simulation run. Re-arange main loop so that simulator

629 reworked idecode.
630
631Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
632
633 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
634 RA. Based on instruction frequency stats, expand additional
635 instructions.
636 * ppc-instructions: Change all `RA == 0' to RA_is_0.
637
638 * ppc-opcode-stupid: Move all but the basic table in -complex into
639 here. Update to new format.
640
641 * Makefile.in (tmp-defines): New target. Force defines.h to always
642 be built. Hence get ppc-opcode-goto to build.
643
644Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
645

647 Implement.
648
649Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
650
651 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
652 to be initialized independant of the rest of the simulation
653 initalization. Otherwize a trace option explictly set from gdb
654 could be overridden by hw_trace.
655
656 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
657
658 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
659 debug.c. It could be much simpler.
660
661Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
662
663 * Some devices support removable media. Add hooks to the disk

680 string array.
681 (print_properties): Adjust.
682 (print_string): Write a string, handling double quotes.

694
695 * For expressions like (RA == 0) that are entered in to the cache
696 as RA_is_0. If possible generate the result of the expression so
697 that the compiler gets a better chance of eliminating dead
698 branches.
699
700 * gen-icache.c (print_icache_extraction): For a cache entry of
701 the form <name>_is_<const> where it is a boolean field, generate
702 the result of the expression instead of the expression its self.
703 (print_icache_body): Remove code that was looking for *_is_0 and
704 then generating corresponding definitions.
705
706 * gen-icache.c (print_icache_struct): If there is no cache, do not
707 output expressions in idecode.h file.
708
709 * gen-icache.c (print_icache_body): Output them here.
710

714 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
715
716Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
717
718 * The code that put values in and extracted values from the cache
719 was too compilicated. The cache table did not allow values to be
720 computed from cache entries. #defines could only be used when a
721 cache was present, remove the restriction.
722
723 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
724 scratch variable is defined when a cache entry is beinf
725 filled. Change the definition of a COMPUTE variable to be defined

737
738 * gen-semantics.c (print_c_semantic): Update use.
739 * gen-idecode.c (print_jump_insn): Update use.
740 * gen-icache.c (print_icache_function): Update use.

742 * igen.c (main): Change 'R' option so that it does not force the
743 cache.
744
745 * configure.in (enable-sim-icache): Clarify description. Make
746 #define one of the defaults regardless of the cache. Probably
747 should revamp and add a separate option.

760
761 * The cap object was retaining a reference to the instance of a
762 device after it was deleted. Instead add and remove cap's from the
763 cap db as they are created and deleted. This ensuring that a
764 capibility is only used during the lifetime of the corresponding
765 object.
766
767 * cap.h, cap.c: Correct cap type - was signed32 should be
768 signed_cell.
769
770 * cap.c (cap_add, cap_remove): New methods for cap object that
771 allow the explicit addition and removal of internal objects that
772 the cap knows about.
773
774 * cap.c (cap_init): Rewrite. Verify that the only objects
775 remaining in the cap data base are those that were entered first.
776 Thse objects will be the permenant ones.

799
800 * The memory "claim" and "release" methods take an address and
801 size as arguments. These may be multi cell values. Initially fix
802 the memory code so that they check/detect this. Leave the

805 * hw_memory.c (hw_memory_instance_claim,
806 hw_memory_instance_release): Handle multi-cell memory devices.

2059 always update the cache_entries semantic and address fields.
2060

2078 same as cpu.[hc].
2079
2080 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2081 name for a lable and then branch to it.
2082

2111
2112Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>

2157 no longer needed).
2158
2159 * psim.c (run_until_stop): Delete the old run_until_stop function
2160 instead calling the idecode_run and idecode_run_until_stop
2161 functions that gen-idecode.c is now creating.

2227
2228 * configure.in: New option --enable-sim-line-nr (default enabled).

3180 * device.c (attach_device_interrupt_edge): New. Interrupt model
3181 did not allow interrupts to be wired up as a general net (edges).
3182 Re-implement so that interrupt events can be passed to multiple
3183 controllers and interrupt controllers can further propogate
3184 interrupt events.
3185
3186 * device.c (attach_device_interrupt_edge) : New, Ditto
3187 * device.c (detach_device_interrupt_edge) : New, Ditto
3188 * device.c (clean_device_interrupt_edges) : New, Ditto
3189 * device.c (device_interrupt_event) : New, Ditto
3190 * device.c (device_interrupt_attach) : New, Ditto
3191 * device.c (device_interrupt_detach) : New, Ditto
3192 * device.c (device_child_interrupt_attach) : New, Ditto
3193 * device.c (device_child_interrupt_detach) : New, Ditto
3194
3195 * device.c (device_attach_interrupt) : Delete old
3196 * device.c (device_detach_interrupt) : Delete old
3197 * device.c (device_interrupt) : Delete old
3198 * device.c (device_interrupt_ack) : Delete old
3199
3200 * device_table.c (unimp_*) : Update to match
3201
3202 * device_table.c (icu_io_write_buffer_callback) : Update to use
3203 interface.
3204 * device_table.c (icu_interrupt_event_callback) : Ditto
3205
3206Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3207
3208 * device.c (external_to_device) : New function that provides a
3209 standard mapping between a devices internal representation (a
3210 pointer) and its external (or what is passed to a client)
3211 representation (a phandle). Implement using the cap object
3212 attached to the root node.
3213
3214 * device.c (device_to_external) : Ditto
3215 * device.c (external_to_device_instance) : Ditto but for ihandle
3216 and device instance.
3217 * device.c (device_instance_to_external) : Ditto
3218
3219 * Makefile (device.o): Add dependency on cap.
3220
3221 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3222 needing to translate between internal and external representations
3223 changed to use the external_to_device et.al. device operations.
3224 * emul_chirp.c (chirp_emul_*) : Ditto
3225
3226 * Makefile (emul_chirp.o): Remove dependency on cap

3229
3230 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3231 on OpenBoot note section.
3232
3233Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3234
3235 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3236 read/write calls for buffer transfers. This will cause a fault to
3237 occure if the transfer fails. CHRP catches the fault while the
3238 others suffer the consequences.
3239 (emul_read_buffer): Ditto.
3240 (emul_write_word): Ditto.
3241 (emul_read_word): Ditto.
3242 (emul_read_string): Ditto.

3245
3246 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3247 emul_generic (emul_blr_instruction): Use a real blr instruction to
3248 return from a client service call.
3249
3250 * emul_chirp.c (services): Add all OpenBoot services to table.
3251
3252 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3253 (emul_chirp_create) : Use names instead of numbers for
3254 instructions being stored in memory.
3255
3256Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
