 212
 213 2001-01-15  Geoffrey Keating  <geoffk@redhat.com>
 214
 215         * emul_netbsd.c (do_open): Translate the flag parameter to the
 216         open syscall to the numbers supported by the host.
 217
 218 2000-12-12  Geoffrey Keating  <geoffk@redhat.com>
 219
 220         * sim-endian.h: Don't have parameters on macro definitions which
 221         are simply renaming functions, to permit use of XCONCAT2 in both

 223
 224 2000-11-15  Jim Blandy  <jimb@redhat.com>
 225

 227         (sim_fetch_register, sim_store_register): Call

 265         * configure: Regenerated to track ../common/aclocal.m4 changes.
 266
 267 1999-04-02  Keith Seitz  <keiths@cygnus.com>
 268

 275 1999-02-22  Jim Lemke  <jlemke@cygnus.com>
 276
 277         * dc-complex: Force expansion on all bits of field BO.

 284
 285 1999-02-01  Jim Blandy  <jimb@zwingli.cygnus.com>
 286
 287         Make the simulator compatible with the MPC750.  It would be nicer
 288         to make this a real multi-sim, but that's more work than we have
 289         time for.
 290         * emul_generic.c (emul_add_tree_options): Only require strict
 291         alignment if it was explicitly requested at configuration time.
 292         Don't make it the default for little-endian machines.
 293         * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
 294         MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
 295         THRM2, THRM3): Plop in the MPC750 SPR registers.
 296         (DABR): This is weird.  This was HID5, but the PPC spec says this
 297         should be DABR; why did some random processor use it for something
 298         else?  The HID5 entry dates back to the original checkin of the
 299         simulator code in 1995, so remove it.
 300         * sim_calls.c (register_names): Delete this; since the user can
 301         now change GDB's list of register names dynamically, we can't
 302         pretend there's a static mapping here.
 303         (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
 304         function to get the register name.  That ought to be accurate.
 305         However, we're changing a compile-time dependency (using the
 306         REGISTER_NAMES macro) into a link- and run-time dependency
 307         (calling REGISTER_NAME, which happens to be a function call on the
 308         PPC).
 309
 310 1999-01-22  Jim Lemke <jlemke@cygnus.com>
 311
 312         * igen.c(gen_semantics_[ch]): setup/use of new option
 313         (-o mpc860c0[=n]).
 314         interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
 315         ppc-instructions(the four branch insn groups): detect problematic br's.
 316         psim.c(is_num - added, psim_options): Parse and init new option.
 317         These changes are currently under #ifdef WITH_OPTION_MPC860C0.
 318
 319 1998-12-01  Ken Raeburn  <raeburn@cygnus.com>
 320
 321         * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.
 322
 323 Fri Nov 20 12:17:28 1998  Andrew Cagney  <cagney@b1.cygnus.com>
 324
 325         * main.c (sim_io_poll_quit): Stub function.
 326
 327         * events.c (SIM_EVENTS_POLL_RATE): Define.
 328         (sim_events_poll): Copy function from common/sim-events.c.
 329         (event_queue_init): Copy scheduling of sim_events_poll from same.
 330
 331         * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
 332         poll the external environment.
 333
 334 1998-11-19  Michael Meissner  <meissner@cygnus.com>
 335
 336         * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
 337         fractional type, so that quiet NaN's aren't treated like
 338         Infinities.
 339
 340 Mon Sep 28 09:42:45 1998  Drew Moseley  <dmoseley@cygnus.com>
 341
 342         * table.c (table_open): For cygwin hosts, we need to use the
 343         return value from the read routine as the number of bytes to
 344         process.  This apparently is due to text-mode vs binary-mode.  If
 345         the mounts are done text-mode, then the size returnedby fstat()

 713         Augment each extracted field with a comment citing the codes
 714         origin.  Should simplify tracking down incorrect cache
 715         extractions.

 717 Tue Feb  4 17:44:51 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 718
 719         * gen-icache.c: Generalize code handling XXX_is_NNN so that it
 720         works for normal and boolean table entries.
 721
 722         * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
 723         valid.  Handle this just like *_{read,write}_register now handles
 724         it.
 725
 726 Mon Feb  3 17:18:16 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>

 732
 733         * psim.c (psim_options): Add new option -c for max-iterations or
 734         count.
 735         (psim_usage): Document.
 736         (psim_max_iterations_exceeded): New function, abort simulation if
 737         max iterations exceeded.
 738
 739         * gen-idecode.c: Re-work the table lookup code so that it assumes
 740         that the entry is a leaf by default.  Simplify the boolean table
 741         entry code so that it involves a mask + test instead of shift +
 742         shift + mask + test.
 743
 744         * gen-idecode.c: Correct generated igen body so that it no drops
 745         or doubles clock interrupts.

 754         if common callback is present.
 755
 756 Wed Jan 29 12:32:41 1997  Michael Meissner  <meissner@tiktok.cygnus.com>
 757
 758         * configure.in (sim_callback): If the gdb is post 4.16, configure
 759         callback support from the common directory.
 760         * configure: Regenerate.
 761
 762         * Makefile.in (BUILT_SRC_WO_CONFIG): Add targ-vals.{h,def} and
 763         targ-map.c.
 764         (GDB_OBJ): Add callback support configured in.
 765         (gentmap,targ-vals.def): Build from common directory.
 766         (targ-vals.h,targ-map.c): Build by running gentmap.
 767         (callback.o): Build from source in common directory.

 770
 771 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 772
 773         * igen wasn't aborting if the opcode table contained no valid
 774         fields.
 775
 776         * misc.c (name2i): Possibly abort if an invalid name is
 777         encountered.
 778         * ld-decode.c: Abort if the table type isn't found.
 779
 780 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 781
 782         * When performance monitoring is disabled, it is still possible to
 783         determine the simulation speed by looking at the number of elapsed
 784         ticks recorded by the event queue.
 785
 786         * psim.c (psim_write_register, psim_read_register): Force the cpu
 787         to zero when it is either of `-1' or `nr_cpus'.  In both cases the
 788         next cpu would be zero any way.
 789
 790         * mon.c (mon_print_info): If possible, print the system cycle
 791         performance.  This is an indication of the number of instructions
 792         per second.
 793
 794 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 795
 796         * The code to allow an event queue to be updated during a signal
 797         was missing.  For main.c, a cntrl-c simulation termination wasn't
 798         handled cleanly.
 799
 800         * The simulation would not correctly restart if an event requested
 801         that the simulation be halted.
 802
 803         * psim.c (psim_options): Add hack to -i option to optionally
 804         include a level vis -i2.
 805         (psim_usage): Document.
 806
 807         * main.c (cntrl_c, cntrl_c_simulation): New functions.  When a
 808         cntrl-c occures schedule an event to halt the simulation.
 809         (main): Catch CNTRL-C signals with the function cntrl_c.
 810
 811         * events.c (event_queue_process): Mask interrupts while
 812         manipulating the async event queue.
 813         (event_queue_init): Ditto.
 814         (event_queue_schedule_after_signal): Ditto.
 815
 816         * events.c (event_queue_process): Mark the event queue as being in
 817         the processing state when processing has started.  Adjust code
 818         so that it is tolerant of halts.
 819         (event_queue_init): Start the event queue out with processing
 820         false.
 821         (event_queue_tick): Check that processing isn't still being
 822         performed.
 823
 824         * gen-idecode.c (print_run_until_stop_body): Call
 825         event_queue_process_events to clear possibly pending events before
 826         starting a simulation run.  Re-arange main loop so that simulator
 827         is correctly restarted when an event halts the simulation.
 828
 829         * psim.c (psim_halt): Handle an event halting the simulation.
 830         * psim.c (psim_init): Adjust initial cpu - == -1 - to match
 831         reworked idecode.
 832
 833 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 834
 835         * ppc-opcode-complex: Correct typo - was expanding ORA instead of
 836         RA.  Based on instruction frequency stats, expand additional
 837         instructions.
 838         * ppc-instructions: Change all `RA == 0' to RA_is_0.
 839
 840         * ppc-opcode-stupid: Move all but the basic table in -complex into
 841         here.  Update to new format.
 842
 843         * Makefile.in (tmp-defines): New target. Force defines.h to always
 844         be built.  Hence get ppc-opcode-goto to build.
 845
 846 Tue Jan 28 13:00:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 847
 848         * hw_com.c (hw_com_instance_read, hw_com_instance_write):
 849         Implement.
 850
 851 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 852
 853         * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
 854         to be initialized independant of the rest of the simulation
 855         initalization.  Otherwize a trace option explictly set from gdb
 856         could be overridden by hw_trace.
 857
 858         * psim.c (psim_options): Clarify reason why the trace ioctl occures.
 859
 860         * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
 861         debug.c.  It could be much simpler.
 862
 863 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 864
 865         * Some devices support removable media.  Add hooks to the disk
 866         device so that it supports this.
 867
 868         * device.c (device_add_string_array_property,
 869         device_find_string_array_property): New functions, manipulate
 870         properties containing an array of strings.
 871         (device_find_string_property): Allow a string array.
 872         (device_init_static_properties): Update.
 873         (device_init_runtime_properties): Update.
 874
 875         * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
 876         media.  If no file image is specified, use the next one in the
 877         image property list.
 878         (hw_disk_init_address): Change the file property so that it is a
 879         string array - use the first entry for the initial file image.
 880
 881         * tree.c (print_string_aray_property): New function - print a
 882         string array.
 883         (print_properties): Adjust.
 884         (print_string): Write a string, handling double quotes.
 885
 886         * device.h: Define an ioctl to `change-media' with an optional new
 887         media image.
 888
 889         * hw_disk.c: Allow floppy disk devices to be specified.
 890
 891         * psim.c (psim_command): New function, parse more complex psim
 892         commands such as "change-media" and "trace".
 893         * sim_calls.c (sim_do_command): Use.
 894
 895 Wed Jan 22 09:38:33 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 896
 897         * For expressions like (RA == 0) that are entered in to the cache
 898         as RA_is_0. If possible generate the result of the expression so
 899         that the compiler gets a better chance of eliminating dead
 900         branches.
 901
 902         * gen-icache.c (print_icache_extraction): For a cache entry of
 903         the form <name>_is_<const> where it is a boolean field, generate
 904         the result of the expression instead of the expression its self.
 905         (print_icache_body): Remove code that was looking for *_is_0 and
 906         then generating corresponding definitions.
 907
 908         * gen-icache.c (print_icache_struct): If there is no cache, do not
 909         output expressions in idecode.h file.
 910
 911         * gen-icache.c (print_icache_body): Output them here.
 912
 913         * ppc-opcode-complex: Clarify constant values for SPR==LR register
 914         expansion.

 916         * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
 917
 918 Wed Jan 22 12:24:52 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 919
 920         * The code that put values in and extracted values from the cache
 921         was too compilicated.  The cache table did not allow values to be
 922         computed from cache entries.  #defines could only be used when a
 923         cache was present, remove the restriction.
 924
 925         * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
 926         scratch variable is defined when a cache entry is beinf
 927         filled. Change the definition of a COMPUTE variable to be defined
 928         when the cache entry is being used.
 929         * gen-icache.c: Update.
 930
 931         * ld-cache.h, ld-cache.c: Change field names so that their meaning
 932         is more obvious.  old_name->field_name, new_name->derived_name.

 934
 935         * gen-icache.h, gen-icache.c (print_icache_body): Make the three
 936         different types of cache code - put into cache, extract from
 937         cache, no cache - an explicit argument to print_icache_body.
 938         * gen-icache.c (print_icache_extraction): Ditto.
 939
 940         * gen-semantics.c (print_c_semantic): Update use.
 941         * gen-idecode.c (print_jump_insn): Update use.
 942         * gen-icache.c (print_icache_function): Update use.
 943
 944         * igen.c (main): Change 'R' option so that it does not force the
 945         cache.
 946
 947         * configure.in (enable-sim-icache): Clarify description.  Make
 948         #define one of the defaults regardless of the cache.  Probably
 949         should revamp and add a separate option.
 950
 951 Tue Jan 21 13:26:10 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 952
 953         * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
 954         partition numbering.
 955         (pk_disklabel_create_instance): Partition 1..4 are valid - not
 956         1..3.
 957         (is_iso9660): New function, verify a CD9660 File system.
 958         (pk_disklabel_create_instance): Start expanding so that active
 959         partition selection is supported.
 960
 961 Mon Jan 20 11:20:15 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 962
 963         * The cap object was retaining a reference to the instance of a
 964         device after it was deleted. Instead add and remove cap's from the
 965         cap db as they are created and deleted.  This ensuring that a
 966         capibility is only used during the lifetime of the corresponding
 967         object.
 968
 969         * cap.h, cap.c: Correct cap type - was signed32 should be
 970         signed_cell.
 971
 972         * cap.c (cap_add, cap_remove): New methods for cap object that
 973         allow the explicit addition and removal of internal objects that
 974         the cap knows about.
 975
 976         * cap.c (cap_init): Rewrite.  Verify that the only objects
 977         remaining in the cap data base are those that were entered first.
 978         Thse objects will be the permenant ones.
 979         * device.c (device_init_address): Remember to initialize the cap
 980         database.
 981
 982         * device.c (device_create_instance_from): Explicitly add device
 983         instances to the cap database.  Simplify create code.
 984         (device_instance_delete): Explicitly remove device instances from
 985         the cap database.
 986
 987         * device.c (device_create_from): Explicitly add a device to the
 988         cap data base.
 989
 990         * device.c (device_create_from): Always set the cap members.

1001
1002         * The memory "claim" and "release" methods take an address and
1003         size as arguments.  These may be multi cell values. Initially fix
1004         the memory code so that they check/detect this.  Leave the
1005         adjustment of any clients to later.
1006
1007         * hw_memory.c (hw_memory_instance_claim,
1008         hw_memory_instance_release): Handle multi-cell memory devices.
1009
1010         * hw_memory.c (hw_memory_instance_claim): Be tolerant towards the
1011         release of memory regions that were not claimed.

1014
1015         * device.h, device.c (device_instance_call_method): Correct return

1031         that are inlined.  These modules are called via a table and are
1032         not made inline.

1034         * hw_init.c (update_for_binary_section): Fix failure to allocate
1035         memory used by the binary in real-mode executions. If "claim"
1036         property is present, allocate memory from the "/chosen/memory"
1037         device.
1038
1039         * emul_chirp.c (emul_chirp_create): Specify that memory should be
1040         claimed when loading a real image.
1041
1042         * hw_memory.c (hw_memory_instance_claim): Don't page align memory

1050         * vm.h (vm_data_map_read_buffer, vm_data_map_write_buffer): Add
1051         optional PROCESSOR & CIA args so that this routine also abort an

2168
2169         * std-config.h (CURRENT_STDIO, current_stdio): New macro. Set up
2170         stdio configuration so that it works in the same way as the rest

2193
2194         * ppc-cache-rules (cache): Change RS and RB to cache instead of

2227
2228         * std-config.h (SEMANTICS_INLINE): By default, mask out the
2229         inlining of semantic functions from DEFAULT_INLINE.  Almost all
2230         configurations call the semantic code via a pointer so there is
2231         little benefit.
2232
2233         * std-config.h (ICACHE_INLINE): Ditto.
2234
2235 Thu Jul 25 20:07:30 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

2262
2263         * gen-idecode.c (print_idecode_switch_illegal): Include a break
2264         when generating illegal instructions.  This was commented out
2265         which is a hangover from looking a at switch statements generated
2266         using indirect jumps.
2267
2268 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2269

2271         Print both a definition for MY_INDEX and MY_PREFIX.
2272         * gen-icache.c (print_icache_function): Adjust.
2273         * gen-idecode.c (print_jump_insn): Adjust.

2275
2276         * gen-support.c (gen_support_h): Add optional include to created
2277         support.h so that, like cpu, it is optionally inlined for all

2279         * inline.h, inline.c: Adjust so that support.[hc] is handled the
2280         same as cpu.[hc].
2281
2282         * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2283         name for a lable and then branch to it.
2284
2285         * ppc-instructions (convert_to_integer, Floating Round to
2286         Single-Precision, Floating Convert from Integer Doubleword): Use

2288
2289 Wed Jul 24 14:02:42 1996  Andrew Cagney  <cagney@sawnoff.highland.com.au>
2290
2291         * gen-idecode.c (print_run_until_stop_body): Too many rparen in
2292         generated code.
2293
2294 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

2299
2300         * configure: rebuild.
2301
2302 Mon Jul 22 23:25:08 1996  Andrew Cagney  <cagney@highland.com.au>
2303
2304         * configure.in (--enable-sim-hardware, --enable-sim-packages): New
2305         configuration options.  Let the user specify the packages or
2306         hardware devices that are to be included in the build.  Makes it
2307         possible for user packages to be specified.
2308
2309         * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2310         hardware instead of checking it using ls.  configure.in should
2311         have taken care of any problems.
2312         (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2313
2314 Mon Jul 22 22:38:59 1996  Andrew Cagney  <cagney@highland.com.au>
2315
2316         * psim.c (psim_options): Enter the argument to the memory size
2317         option directly into the device tree.  Was using atol() which is
2318         dangerously non portable.
2319
2320 Mon Jul 22 22:17:08 1996  Andrew Cagney  <cagney@highland.com.au>
2321
2322         * configure.in (icache): Extend icache flag to include an insn
2323         option.  If specifyed the insn - aka instruction - is included in

2326
2327         * igen.c (main), igen.h: Add option -S - inSn - for specifying

2340
2341         * emul_generic.c (emul_add_tree_options): Was incorrectly setting
2342         the strict-alignment option when hardwired for non-strict
2343         alignment.
2344
2345 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2346
2347         * gen-semantics.c: Make the my_index variable a macro MY_INDEX.
2348
2349         * ppc-instructions: Adjust so that references are to MY_INDEX and
2350         not my_index.
2351
2352 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2353
2354         * gen-idecode.c: Output the complete run_until_stop function
2355         instead of just the code to handle a single instruction issue.
2356         * : Have the generated idecode.c include inline.c (instead of psim.c).
2357
2358         * std-config.h: Change psim.c so that it isn't inlined (as this is
2359         no longer needed).
2360
2361         * psim.c (run_until_stop): Delete the old run_until_stop function
2362         instead calling the idecode_run and idecode_run_until_stop
2363         functions that gen-idecode.c is now creating.
2364
2365 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2366
2367         * dgen.c: Maintenance - update to use new features found in lf.c.

2373
2374         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
2375         eliminate trace statements.
2376
2377         * debug.c: Change trace format so that it is consistent

2390         corresponding call to ITRACE so that it still matches.
2391
2392         * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
2393         of ITRACE.  The CPP line directives would have previously set the
2394         line-nr and file name so ITRACE isn't needed.
2395
2396 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2397
2398         * gen-idecode.c (print_jump_until_stop_body): New function and
2399         idecode generation option.  Instead of generating and calling
2400         separate functions containing the semantic and icache code
2401         generate a single monolythic function and use goto's (and GCC's
2402         indirect jump) to move between code blocks.

2405
2406         * configure.in: New option --enable-sim-jump (default disabled)
2407
2408         * ppc-instructions: Eliminate any uses of labels and goto's.

2410         is being create.
2411
2412         * ppc-opcode-jump: New file.  Set of opcode rules useful when
2413         testing jumping idecodes.

2416
2417         * gen-idecode.c: Optionally include the semantic code for an
2418         instruction in the function that is doing the decoding.
2419
2420         * igen.c: Add option (-C) to generate semantics in the instruction
2421         decode functions.
2422
2423         * configure.in (--enable-sim-icache): Accept an option list such
2424         as 1024,define.  Add a new choice to the list - semantic - which
2425         will cause igen to generate instruction decode functions that
2426         include the corresponding semantic code.
2427
2428 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2429
2430         * configure.in: New option --enable-sim-line-nr (default enabled).
2431         Enable/disable the inclusion of CPP line directives in the
2432         generated files.  Such directives refer back to the source files
2433         used when generating the simulator code.
2434
2435         * Makefile.in (sim_line_nr): Pass to igen.
2436
2437 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2438
2439         * igen.c (main): Revamp the options so that more letters are
2440         available.
2441
2442         * configure.in: Adjust to match igen's revamped options
2443
2444 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2445
2446         * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2447         that they use the same technique as igen (ie a dummy targets
2448         tmp-pk and tmp-hw are created).
2449
2450 Mon Jun 24 22:28:00 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
