 456
 457 2000-12-12  Geoffrey Keating  <geoffk@redhat.com>
 458
 459         * sim-endian.h: Don't have parameters on macro definitions which
 460         are simply renaming functions, to permit use of XCONCAT2 in both
 461         the macro name and the arguments in a use of such a definition.
 462
 463 2000-11-15  Jim Blandy  <jimb@redhat.com>
 464
 465         * sim_calls.c: Doc fix.
 466         (sim_fetch_register, sim_store_register): Call

 505
 506 1999-04-02  Keith Seitz  <keiths@cygnus.com>
 507
 508         * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
 509         the frequency at which the poll_quit callback is called.
 510         (poll_quit_count): New global.
 511         (sim_io_poll_quit): Only call the poll_quit callback
 512         after the specified POLL_QUIT_INTERVAL.
 513
 514 1999-02-22  Jim Lemke  <jlemke@cygnus.com>
 515
 516         * dc-complex: Force expansion on all bits of field BO.
 517         Previously, the least-significant (prediction) bit was ignored.

 522         * interrupts.c (program_interrupt): Added handling for above interrupt.
 523
 524 1999-02-01  Jim Blandy  <jimb@zwingli.cygnus.com>
 525
 526         Make the simulator compatible with the MPC750.  It would be nicer
 527         to make this a real multi-sim, but that's more work than we have
 528         time for.
 529         * emul_generic.c (emul_add_tree_options): Only require strict
 530         alignment if it was explicitly requested at configuration time.
 531         Don't make it the default for little-endian machines.
 532         * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
 533         MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
 534         THRM2, THRM3): Plop in the MPC750 SPR registers.
 535         (DABR): This is weird.  This was HID5, but the PPC spec says this
 536         should be DABR; why did some random processor use it for something
 537         else?  The HID5 entry dates back to the original checkin of the
 538         simulator code in 1995, so remove it.
 539         * sim_calls.c (register_names): Delete this; since the user can
 540         now change GDB's list of register names dynamically, we can't
 541         pretend there's a static mapping here.
 542         (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
 543         function to get the register name.  That ought to be accurate.
 544         However, we're changing a compile-time dependency (using the
 545         REGISTER_NAMES macro) into a link- and run-time dependency
 546         (calling REGISTER_NAME, which happens to be a function call on the
 547         PPC).
 548
 549 1999-01-22  Jim Lemke <jlemke@cygnus.com>
 550
 551         * igen.c(gen_semantics_[ch]): setup/use of new option
 552         (-o mpc860c0[=n]).
 553         interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
 554         ppc-instructions(the four branch insn groups): detect problematic br's.
 555         psim.c(is_num - added, psim_options): Parse and init new option.
 556         These changes are currently under #ifdef WITH_OPTION_MPC860C0.
 557
 558 1998-12-01  Ken Raeburn  <raeburn@cygnus.com>
 559
 560         * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

 564         * main.c (sim_io_poll_quit): Stub function.
 565
 566         * events.c (SIM_EVENTS_POLL_RATE): Define.
 567         (sim_events_poll): Copy function from common/sim-events.c.
 568         (event_queue_init): Copy scheduling of sim_events_poll from same.
 569
 570         * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
 571         poll the external environment.
 572
 573 1998-11-19  Michael Meissner  <meissner@cygnus.com>
 574
 575         * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
 576         fractional type, so that quiet NaN's aren't treated like
 577         Infinities.
 578
 579 Mon Sep 28 09:42:45 1998  Drew Moseley  <dmoseley@cygnus.com>
 580
 581         * table.c (table_open): For cygwin hosts, we need to use the
 582         return value from the read routine as the number of bytes to
 583         process.  This apparently is due to text-mode vs binary-mode.  If
 584         the mounts are done text-mode, then the size returnedby fstat()
 585         may be different than the number of bytes "read" in text mode.
 586
 587 Sun Oct  4 00:50:47 1998  Felix Lee  <flee@cygnus.com>
 588
 589         * emul_netbsd.c (do_open): fix order-of-evaluation problem.

 609
 610 Tue May 12 12:10:33 PDT 1998  James Ingham  <jingham@leda.cygnus.com>
 611
 612         * Makefile.in: The run target depended on a target psim$(EXEEXT),
 613         but there was no such target, only plain psim.  So I changed the
 614         run target to depend on psim.

 619         now defined in ../common/aclocal.m4, and the double definition causes
 620         problems with AC_SUBST of EXEEXT.
 621         * configure:  Regenerate.

1054
1055         * events.c (event_queue_process): Mark the event queue as being in
1056         the processing state when processing has started.  Adjust code
1057         so that it is tolerant of halts.
1058         (event_queue_init): Start the event queue out with processing
1059         false.
1060         (event_queue_tick): Check that processing isn't still being

1072 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1073
1074         * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1075         RA.  Based on instruction frequency stats, expand additional
1076         instructions.
1077         * ppc-instructions: Change all `RA == 0' to RA_is_0.
1078
1079         * ppc-opcode-stupid: Move all but the basic table in -complex into

1091
1092         * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
1093         to be initialized independant of the rest of the simulation
1094         initalization.  Otherwize a trace option explictly set from gdb
1095         could be overridden by hw_trace.
1096
1097         * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1098
1099         * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1100         debug.c.  It could be much simpler.
1101
1102 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1103

1118         string array - use the first entry for the initial file image.
1119
1120         * tree.c (print_string_aray_property): New function - print a
1121         string array.
1122         (print_properties): Adjust.

1133
1134 Wed Jan 22 09:38:33 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1135
1136         * For expressions like (RA == 0) that are entered in to the cache
1137         as RA_is_0. If possible generate the result of the expression so
1138         that the compiler gets a better chance of eliminating dead
1139         branches.
1140
1141         * gen-icache.c (print_icache_extraction): For a cache entry of
1142         the form <name>_is_<const> where it is a boolean field, generate
1143         the result of the expression instead of the expression its self.
1144         (print_icache_body): Remove code that was looking for *_is_0 and

1158
1159         * The code that put values in and extracted values from the cache
1160         was too compilicated.  The cache table did not allow values to be
1161         computed from cache entries.  #defines could only be used when a
1162         cache was present, remove the restriction.
1163
1164         * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
1165         scratch variable is defined when a cache entry is beinf
1166         filled. Change the definition of a COMPUTE variable to be defined
1167         when the cache entry is being used.

1169
1170         * ld-cache.h, ld-cache.c: Change field names so that their meaning

1173
1174         * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1175         different types of cache code - put into cache, extract from
1176         cache, no cache - an explicit argument to print_icache_body.
1177         * gen-icache.c (print_icache_extraction): Ditto.
1178
1179         * gen-semantics.c (print_c_semantic): Update use.

1184         cache.
1185
1186         * configure.in (enable-sim-icache): Clarify description.  Make
1187         #define one of the defaults regardless of the cache.  Probably
1188         should revamp and add a separate option.

1197         (pk_disklabel_create_instance): Start expanding so that active
1198         partition selection is supported.
1199

1201
1202         * The cap object was retaining a reference to the instance of a
1203         device after it was deleted. Instead add and remove cap's from the
1204         cap db as they are created and deleted.  This ensuring that a
1205         capibility is only used during the lifetime of the corresponding
1206         object.
1207
1208         * cap.h, cap.c: Correct cap type - was signed32 should be

1212         allow the explicit addition and removal of internal objects that
1213         the cap knows about.
1214
1215         * cap.c (cap_init): Rewrite.  Verify that the only objects
1216         remaining in the cap data base are those that were entered first.
1217         Thse objects will be the permenant ones.
1218         * device.c (device_init_address): Remember to initialize the cap
1219         database.
1220
1221         * device.c (device_create_instance_from): Explicitly add device

1240
1241         * The memory "claim" and "release" methods take an address and
1242         size as arguments.  These may be multi cell values. Initially fix
1243         the memory code so that they check/detect this.  Leave the
1244         adjustment of any clients to later.
1245
1246         * hw_memory.c (hw_memory_instance_claim,
1247         hw_memory_instance_release): Handle multi-cell memory devices.

1273         * hw_init.c (update_for_binary_section): Fix failure to allocate
1274         memory used by the binary in real-mode executions. If "claim"

1277
1278         * emul_chirp.c (emul_chirp_create): Specify that memory should be

2432
2433         * ppc-cache-rules (cache): Change RS and RB to cache instead of

2466
2467         * std-config.h (SEMANTICS_INLINE): By default, mask out the
2468         inlining of semantic functions from DEFAULT_INLINE.  Almost all
2469         configurations call the semantic code via a pointer so there is
2470         little benefit.
2471
2472         * std-config.h (ICACHE_INLINE): Ditto.
2473
2474 Thu Jul 25 20:07:30 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

2501
2502         * gen-idecode.c (print_idecode_switch_illegal): Include a break
2503         when generating illegal instructions.  This was commented out
2504         which is a hangover from looking a at switch statements generated
2505         using indirect jumps.
2506
2507 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2508

2514
2515         * gen-support.c (gen_support_h): Add optional include to created
2516         support.h so that, like cpu, it is optionally inlined for all

2518         * inline.h, inline.c: Adjust so that support.[hc] is handled the
2519         same as cpu.[hc].
2520
2521         * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2522         name for a lable and then branch to it.
2523
2524         * ppc-instructions (convert_to_integer, Floating Round to
2525         Single-Precision, Floating Convert from Integer Doubleword): Use
2526         LABEL and GOTO instead of the recently added switch statements.
2527
2528 Wed Jul 24 14:02:42 1996  Andrew Cagney  <cagney@sawnoff.highland.com.au>
2529
2530         * gen-idecode.c (print_run_until_stop_body): Too many rparen in

2538
2539         * configure: rebuild.
2540
2541 Mon Jul 22 23:25:08 1996  Andrew Cagney  <cagney@highland.com.au>
2542
2543         * configure.in (--enable-sim-hardware, --enable-sim-packages): New
2544         configuration options.  Let the user specify the packages or
2545         hardware devices that are to be included in the build.  Makes it
2546         possible for user packages to be specified.
2547
2548         * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2549         hardware instead of checking it using ls.  configure.in should
2550         have taken care of any problems.
2551         (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2552
2553 Mon Jul 22 22:38:59 1996  Andrew Cagney  <cagney@highland.com.au>
2554
2555         * psim.c (psim_options): Enter the argument to the memory size
2556         option directly into the device tree.  Was using atol() which is
2557         dangerously non portable.
2558

2560
2561         * configure.in (icache): Extend icache flag to include an insn
2562         option.  If specifyed the insn - aka instruction - is included in

2579
2580         * emul_generic.c (emul_add_tree_options): Was incorrectly setting

2589         not my_index.
2590
2591 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2592
2593         * gen-idecode.c: Output the complete run_until_stop function
2594         instead of just the code to handle a single instruction issue.
2595         * : Have the generated idecode.c include inline.c (instead of psim.c).
2596
2597         * std-config.h: Change psim.c so that it isn't inlined (as this is
2598         no longer needed).
2599
2600         * psim.c (run_until_stop): Delete the old run_until_stop function
2601         instead calling the idecode_run and idecode_run_until_stop
2602         functions that gen-idecode.c is now creating.
2603
2604 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2605
2606         * dgen.c: Maintenance - update to use new features found in lf.c.

2612
2613         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
2614         eliminate trace statements.
2615
2616         * debug.c: Change trace format so that it is consistent

2620         source line number to the instruction's informational entry.
2621
2622         * debug.c (ITRACE): Use the itable (and my_index) to get the
2623         current instructions name and source line number.
2624
2625         * gen-semantics.c, gen-icache.c: Adjust generated ITRACE calls to
2626         match new interface.
2627
2628         * emul_bugapi.c (emul_bugapi_instruction_call): Adjust
2629         corresponding call to ITRACE so that it still matches.
2630
2631         * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
2632         of ITRACE.  The CPP line directives would have previously set the
2633         line-nr and file name so ITRACE isn't needed.
2634
2635 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2636
2637         * gen-idecode.c (print_jump_until_stop_body): New function and
2638         idecode generation option.  Instead of generating and calling
2639         separate functions containing the semantic and icache code
2640         generate a single monolythic function and use goto's (and GCC's
2641         indirect jump) to move between code blocks.
2642
2643         * Makefile.in: Add sim_jump flag to those passed to igen.
2644
2645         * configure.in: New option --enable-sim-jump (default disabled)
2646
2647         * ppc-instructions: Eliminate any uses of labels and goto's.
2648         These result in duplicate declarations when a single flat function
2649         is being create.
2650
2651         * ppc-opcode-jump: New file.  Set of opcode rules useful when
2652         testing jumping idecodes.

2655
2656         * gen-idecode.c: Optionally include the semantic code for an
2657         instruction in the function that is doing the decoding.
2658
2659         * igen.c: Add option (-C) to generate semantics in the instruction
2660         decode functions.
2661
2662         * configure.in (--enable-sim-icache): Accept an option list such
2663         as 1024,define.  Add a new choice to the list - semantic - which
2664         will cause igen to generate instruction decode functions that
2665         include the corresponding semantic code.
2666
2667 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2668

2670         Enable/disable the inclusion of CPP line directives in the
2671         generated files.  Such directives refer back to the source files
2672         used when generating the simulator code.
2673
2674         * Makefile.in (sim_line_nr): Pass to igen.
2675
2676 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2677
2678         * igen.c (main): Revamp the options so that more letters are
2679         available.
2680
2681         * configure.in: Adjust to match igen's revamped options
2682
2683 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2684
2685         * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2686         that they use the same technique as igen (ie a dummy targets
2687         tmp-pk and tmp-hw are created).
2688
2689 Mon Jun 24 22:28:00 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2690
2691         * Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.

2704         * igen.c: Adjust.
2705
2706         * gen-support.[ch]: New files. Output the support functions (found
2707         in the ppc-instructions file) into a separate file.

2721         reading code from the rest of igen.c.  Re-design the filter so that
2722         it works inclusivly not exclusivly.
2723         * igen.c: Remove the opcode filter table loading code.
2724         * Makefile.in (filter.o): Adjust
2725         * configure.in: Adjust filter flag so that default includes 32bit
2726         and floating point.
2727         * ppc-instructions: Clean up filter fields so that only in use
2728         entries are specifed (ie delete `be').

2753
2754         * device_table.h: Don't pass the parent device into a devices
2755         create function.  This makes the create function consistent with
