SS		 61999-04-02 Keith Seitz <keiths@cygnus.com>
7
8 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
9 the frequency at which the poll_quit callback is called.
10 (poll_quit_count): New global.
11 (sim_io_poll_quit): Only call the poll_quit callback
12 after the specified POLL_QUIT_INTERVAL.
13
141999-02-22 Jim Lemke <jlemke@cygnus.com>
15
16 * dc-complex: Force expansion on all bits of field BO.
17 Previously, the least-significant (prediction) bit was ignored.
18 * ppc-instructions (conditional branches): Implement mpc860c0 option.
19 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
20 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
21 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
22 * interrupts.c (program_interrupt): Added handling for above interrupt.

26 Make the simulator compatible with the MPC750. It would be nicer
27 to make this a real multi-sim, but that's more work than we have
28 time for.
29 * emul_generic.c (emul_add_tree_options): Only require strict
30 alignment if it was explicitly requested at configuration time.
31 Don't make it the default for little-endian machines.
32 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
33 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
34 THRM2, THRM3): Plop in the MPC750 SPR registers.
35 (DABR): This is weird. This was HID5, but the PPC spec says this
36 should be DABR; why did some random processor use it for something
37 else? The HID5 entry dates back to the original checkin of the
38 simulator code in 1995, so remove it.
39 * sim_calls.c (register_names): Delete this; since the user can
40 now change GDB's list of register names dynamically, we can't
41 pretend there's a static mapping here.
42 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
43 function to get the register name. That ought to be accurate.
44 However, we're changing a compile-time dependency (using the
45 REGISTER_NAMES macro) into a link- and run-time dependency
46 (calling REGISTER_NAME, which happens to be a function call on the
47 PPC).
48
491999-01-22 Jim Lemke <jlemke@cygnus.com>
50
51 * igen.c(gen_semantics_[ch]): setup/use of new option
52 (-o mpc860c0[=n]).
53 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
54 ppc-instructions(the four branch insn groups): detect problematic br's.
55 psim.c(is_num - added, psim_options): Parse and init new option.
56 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
57
581998-12-01 Ken Raeburn <raeburn@cygnus.com>
59
60 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.
61
62Fri Nov 20 12:17:28 1998 Andrew Cagney <cagney@b1.cygnus.com>
63
64 * main.c (sim_io_poll_quit): Stub function.
65
66 * events.c (SIM_EVENTS_POLL_RATE): Define.
67 (sim_events_poll): Copy function from common/sim-events.c.
68 (event_queue_init): Copy scheduling of sim_events_poll from same.
69
70 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
71 poll the external environment.
72
731998-11-19 Michael Meissner <meissner@cygnus.com>
74
75 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
76 fractional type, so that quiet NaN's aren't treated like
77 Infinities.
78
79Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
80
81 * table.c (table_open): For cygwin hosts, we need to use the
82 return value from the read routine as the number of bytes to
83 process. This apparently is due to text-mode vs binary-mode. If
84 the mounts are done text-mode, then the size returnedby fstat()
85 may be different than the number of bytes "read" in text mode.
86
87Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
88
89 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

106 * configure: Regenerate.
107 * emul_{netbsd,unix}.c (toplevel): No longer try to include
108 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
109
110Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
111
112 * Makefile.in: The run target depended on a target psim$(EXEEXT),
113 but there was no such target, only plain psim. So I changed the
114 run target to depend on psim.
115
116Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
117
118 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
119 now defined in ../common/aclocal.m4, and the double definition causes
120 problems with AC_SUBST of EXEEXT.
121 * configure: Regenerate.

475 (psim_max_iterations_exceeded): New function, abort simulation if
476 max iterations exceeded.
477
478 * gen-idecode.c: Re-work the table lookup code so that it assumes
479 that the entry is a leaf by default. Simplify the boolean table
480 entry code so that it involves a mask + test instead of shift +
481 shift + mask + test.
482
483 * gen-idecode.c: Correct generated igen body so that it no drops
484 or doubles clock interrupts.
485
486

519Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
520
521 * When performance monitoring is disabled, it is still possible to
522 determine the simulation speed by looking at the number of elapsed
523 ticks recorded by the event queue.
524
525 * psim.c (psim_write_register, psim_read_register): Force the cpu
526 to zero when it is either of `-1' or `nr_cpus'. In both cases the
527 next cpu would be zero any way.
528
529 * mon.c (mon_print_info): If possible, print the system cycle
530 performance. This is an indication of the number of instructions
531 per second.
532
533Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
534
535 * The code to allow an event queue to be updated during a signal
536 was missing. For main.c, a cntrl-c simulation termination wasn't
537 handled cleanly.
538
539 * The simulation would not correctly restart if an event requested
540 that the simulation be halted.
541
542 * psim.c (psim_options): Add hack to -i option to optionally
543 include a level vis -i2.
544 (psim_usage): Document.

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

569 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
570 reworked idecode.
571
572Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
573
574 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
575 RA. Based on instruction frequency stats, expand additional
576 instructions.
577 * ppc-instructions: Change all `RA == 0' to RA_is_0.
578
579 * ppc-opcode-stupid: Move all but the basic table in -complex into
580 here. Update to new format.
581
582 * Makefile.in (tmp-defines): New target. Force defines.h to always
583 be built. Hence get ppc-opcode-goto to build.
584
585Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
586

588 Implement.
589
590Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
591
592 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
593 to be initialized independant of the rest of the simulation
594 initalization. Otherwize a trace option explictly set from gdb
595 could be overridden by hw_trace.
596
597 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
598
599 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
600 debug.c. It could be much simpler.
601
602Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
603
604 * Some devices support removable media. Add hooks to the disk

635
636 * For expressions like (RA == 0) that are entered in to the cache
637 as RA_is_0. If possible generate the result of the expression so
638 that the compiler gets a better chance of eliminating dead
639 branches.
640
641 * gen-icache.c (print_icache_extraction): For a cache entry of
642 the form <name>_is_<const> where it is a boolean field, generate

645 then generating corresponding definitions.
646
647 * gen-icache.c (print_icache_struct): If there is no cache, do not
648 output expressions in idecode.h file.
649
650 * gen-icache.c (print_icache_body): Output them here.

656
657Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
658
659 * The code that put values in and extracted values from the cache
660 was too compilicated. The cache table did not allow values to be
661 computed from cache entries. #defines could only be used when a
662 cache was present, remove the restriction.
663
664 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
665 scratch variable is defined when a cache entry is beinf

678
679 * gen-semantics.c (print_c_semantic): Update use.
680 * gen-idecode.c (print_jump_insn): Update use.
681 * gen-icache.c (print_icache_function): Update use.

683 * igen.c (main): Change 'R' option so that it does not force the
684 cache.
685
686 * configure.in (enable-sim-icache): Clarify description. Make
687 #define one of the defaults regardless of the cache. Probably
688 should revamp and add a separate option.
689

701
702 * The cap object was retaining a reference to the instance of a
703 device after it was deleted. Instead add and remove cap's from the
704 cap db as they are created and deleted. This ensuring that a
705 capibility is only used during the lifetime of the corresponding
706 object.
707
708 * cap.h, cap.c: Correct cap type - was signed32 should be
709 signed_cell.
710
711 * cap.c (cap_add, cap_remove): New methods for cap object that
712 allow the explicit addition and removal of internal objects that
713 the cap knows about.
714
715 * cap.c (cap_init): Rewrite. Verify that the only objects
716 remaining in the cap data base are those that were entered first.
717 Thse objects will be the permenant ones.

745
746 * hw_memory.c (hw_memory_instance_claim,
747 hw_memory_instance_release): Handle multi-cell memory devices.

2019 same as cpu.[hc].
2020
2021 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2022 name for a lable and then branch to it.
2023

2052
2053Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>

2097 * std-config.h: Change psim.c so that it isn't inlined (as this is
2098 no longer needed).
2099
2100 * psim.c (run_until_stop): Delete the old run_until_stop function
2101 instead calling the idecode_run and idecode_run_until_stop
2102 functions that gen-idecode.c is now creating.

2168
2169 * configure.in: New option --enable-sim-line-nr (default enabled).
