SS		 101999-04-02 Keith Seitz <keiths@cygnus.com>
11
12 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
13 the frequency at which the poll_quit callback is called.
14 (poll_quit_count): New global.
15 (sim_io_poll_quit): Only call the poll_quit callback
16 after the specified POLL_QUIT_INTERVAL.
17
181999-02-22 Jim Lemke <jlemke@cygnus.com>
19
20 * dc-complex: Force expansion on all bits of field BO.
21 Previously, the least-significant (prediction) bit was ignored.
22 * ppc-instructions (conditional branches): Implement mpc860c0 option.
23 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
24 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
25 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
26 * interrupts.c (program_interrupt): Added handling for above interrupt.

30 Make the simulator compatible with the MPC750. It would be nicer
31 to make this a real multi-sim, but that's more work than we have
32 time for.
33 * emul_generic.c (emul_add_tree_options): Only require strict
34 alignment if it was explicitly requested at configuration time.
35 Don't make it the default for little-endian machines.
36 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
37 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
38 THRM2, THRM3): Plop in the MPC750 SPR registers.
39 (DABR): This is weird. This was HID5, but the PPC spec says this
40 should be DABR; why did some random processor use it for something
41 else? The HID5 entry dates back to the original checkin of the
42 simulator code in 1995, so remove it.
43 * sim_calls.c (register_names): Delete this; since the user can
44 now change GDB's list of register names dynamically, we can't
45 pretend there's a static mapping here.
46 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
47 function to get the register name. That ought to be accurate.
48 However, we're changing a compile-time dependency (using the
49 REGISTER_NAMES macro) into a link- and run-time dependency
50 (calling REGISTER_NAME, which happens to be a function call on the
51 PPC).
52
531999-01-22 Jim Lemke <jlemke@cygnus.com>
54
55 * igen.c(gen_semantics_[ch]): setup/use of new option
56 (-o mpc860c0[=n]).
57 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
58 ppc-instructions(the four branch insn groups): detect problematic br's.
59 psim.c(is_num - added, psim_options): Parse and init new option.
60 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
61
621998-12-01 Ken Raeburn <raeburn@cygnus.com>
63
64 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.
65
66Fri Nov 20 12:17:28 1998 Andrew Cagney <cagney@b1.cygnus.com>
67
68 * main.c (sim_io_poll_quit): Stub function.
69
70 * events.c (SIM_EVENTS_POLL_RATE): Define.
71 (sim_events_poll): Copy function from common/sim-events.c.
72 (event_queue_init): Copy scheduling of sim_events_poll from same.
73
74 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
75 poll the external environment.
76
771998-11-19 Michael Meissner <meissner@cygnus.com>
78
79 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
80 fractional type, so that quiet NaN's aren't treated like
81 Infinities.
82
83Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
84
85 * table.c (table_open): For cygwin hosts, we need to use the
86 return value from the read routine as the number of bytes to
87 process. This apparently is due to text-mode vs binary-mode. If
88 the mounts are done text-mode, then the size returnedby fstat()
89 may be different than the number of bytes "read" in text mode.
90
91Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
92
93 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

110 * configure: Regenerate.
111 * emul_{netbsd,unix}.c (toplevel): No longer try to include
112 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
113
114Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
115
116 * Makefile.in: The run target depended on a target psim$(EXEEXT),
117 but there was no such target, only plain psim. So I changed the
118 run target to depend on psim.
119
120Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
121
122 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
123 now defined in ../common/aclocal.m4, and the double definition causes
124 problems with AC_SUBST of EXEEXT.
125 * configure: Regenerate.

480 max iterations exceeded.
481
482 * gen-idecode.c: Re-work the table lookup code so that it assumes
483 that the entry is a leaf by default. Simplify the boolean table
484 entry code so that it involves a mask + test instead of shift +
485 shift + mask + test.
486
487 * gen-idecode.c: Correct generated igen body so that it no drops
488 or doubles clock interrupts.
489

523Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
524
525 * When performance monitoring is disabled, it is still possible to
526 determine the simulation speed by looking at the number of elapsed
527 ticks recorded by the event queue.
528
529 * psim.c (psim_write_register, psim_read_register): Force the cpu
530 to zero when it is either of `-1' or `nr_cpus'. In both cases the
531 next cpu would be zero any way.
532
533 * mon.c (mon_print_info): If possible, print the system cycle
534 performance. This is an indication of the number of instructions
535 per second.
536
537Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
538
539 * The code to allow an event queue to be updated during a signal
540 was missing. For main.c, a cntrl-c simulation termination wasn't
541 handled cleanly.
542
543 * The simulation would not correctly restart if an event requested
544 that the simulation be halted.
545
546 * psim.c (psim_options): Add hack to -i option to optionally
547 include a level vis -i2.
548 (psim_usage): Document.

560 the processing state when processing has started. Adjust code
561 so that it is tolerant of halts.
562 (event_queue_init): Start the event queue out with processing
563 false.
564 (event_queue_tick): Check that processing isn't still being
565 performed.
566
567 * gen-idecode.c (print_run_until_stop_body): Call
568 event_queue_process_events to clear possibly pending events before
569 starting a simulation run. Re-arange main loop so that simulator
570 is correctly restarted when an event halts the simulation.

575
576Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
577
578 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
579 RA. Based on instruction frequency stats, expand additional
580 instructions.
581 * ppc-instructions: Change all `RA == 0' to RA_is_0.
582
583 * ppc-opcode-stupid: Move all but the basic table in -complex into
584 here. Update to new format.
585
586 * Makefile.in (tmp-defines): New target. Force defines.h to always
587 be built. Hence get ppc-opcode-goto to build.
588
589Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
590

592 Implement.
593
594Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
595
596 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
597 to be initialized independant of the rest of the simulation
598 initalization. Otherwize a trace option explictly set from gdb
599 could be overridden by hw_trace.
600
601 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
602
603 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
604 debug.c. It could be much simpler.
605
606Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
607
608 * Some devices support removable media. Add hooks to the disk

639
640 * For expressions like (RA == 0) that are entered in to the cache
641 as RA_is_0. If possible generate the result of the expression so
642 that the compiler gets a better chance of eliminating dead
643 branches.
644
645 * gen-icache.c (print_icache_extraction): For a cache entry of
646 the form <name>_is_<const> where it is a boolean field, generate

649 then generating corresponding definitions.
650
651 * gen-icache.c (print_icache_struct): If there is no cache, do not
652 output expressions in idecode.h file.

660
661Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
662
663 * The code that put values in and extracted values from the cache
664 was too compilicated. The cache table did not allow values to be
665 computed from cache entries. #defines could only be used when a
666 cache was present, remove the restriction.
667
668 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
669 scratch variable is defined when a cache entry is beinf

682
683 * gen-semantics.c (print_c_semantic): Update use.
684 * gen-idecode.c (print_jump_insn): Update use.
685 * gen-icache.c (print_icache_function): Update use.

687 * igen.c (main): Change 'R' option so that it does not force the
688 cache.
689
690 * configure.in (enable-sim-icache): Clarify description. Make
691 #define one of the defaults regardless of the cache. Probably
692 should revamp and add a separate option.
693

705
706 * The cap object was retaining a reference to the instance of a
707 device after it was deleted. Instead add and remove cap's from the
708 cap db as they are created and deleted. This ensuring that a
709 capibility is only used during the lifetime of the corresponding
710 object.
711
712 * cap.h, cap.c: Correct cap type - was signed32 should be
713 signed_cell.
714
715 * cap.c (cap_add, cap_remove): New methods for cap object that
716 allow the explicit addition and removal of internal objects that
717 the cap knows about.
718
719 * cap.c (cap_init): Rewrite. Verify that the only objects
720 remaining in the cap data base are those that were entered first.
721 Thse objects will be the permenant ones.

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

2023 same as cpu.[hc].
2024
2025 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2026 name for a lable and then branch to it.
2027

2101 * std-config.h: Change psim.c so that it isn't inlined (as this is
2102 no longer needed).
2103
2104 * psim.c (run_until_stop): Delete the old run_until_stop function
2105 instead calling the idecode_run and idecode_run_until_stop
2106 functions that gen-idecode.c is now creating.

2172
2173 * configure.in: New option --enable-sim-line-nr (default enabled).
