SS		 291999-04-02 Keith Seitz <keiths@cygnus.com>
30
31 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
32 the frequency at which the poll_quit callback is called.
33 (poll_quit_count): New global.
34 (sim_io_poll_quit): Only call the poll_quit callback
35 after the specified POLL_QUIT_INTERVAL.
36
371999-02-22 Jim Lemke <jlemke@cygnus.com>
38

49 Make the simulator compatible with the MPC750. It would be nicer
50 to make this a real multi-sim, but that's more work than we have
51 time for.
52 * emul_generic.c (emul_add_tree_options): Only require strict
53 alignment if it was explicitly requested at configuration time.
54 Don't make it the default for little-endian machines.
55 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
56 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
57 THRM2, THRM3): Plop in the MPC750 SPR registers.
58 (DABR): This is weird. This was HID5, but the PPC spec says this
59 should be DABR; why did some random processor use it for something
60 else? The HID5 entry dates back to the original checkin of the
61 simulator code in 1995, so remove it.
62 * sim_calls.c (register_names): Delete this; since the user can
63 now change GDB's list of register names dynamically, we can't
64 pretend there's a static mapping here.
65 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
66 function to get the register name. That ought to be accurate.
67 However, we're changing a compile-time dependency (using the
68 REGISTER_NAMES macro) into a link- and run-time dependency
69 (calling REGISTER_NAME, which happens to be a function call on the
70 PPC).
71
721999-01-22 Jim Lemke <jlemke@cygnus.com>
73
74 * igen.c(gen_semantics_[ch]): setup/use of new option
75 (-o mpc860c0[=n]).
76 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
77 ppc-instructions(the four branch insn groups): detect problematic br's.
78 psim.c(is_num - added, psim_options): Parse and init new option.
79 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
80
811998-12-01 Ken Raeburn <raeburn@cygnus.com>
82
83 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.
84
85Fri Nov 20 12:17:28 1998 Andrew Cagney <cagney@b1.cygnus.com>
86
87 * main.c (sim_io_poll_quit): Stub function.
88
89 * events.c (SIM_EVENTS_POLL_RATE): Define.
90 (sim_events_poll): Copy function from common/sim-events.c.
91 (event_queue_init): Copy scheduling of sim_events_poll from same.
92
93 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
94 poll the external environment.
95
961998-11-19 Michael Meissner <meissner@cygnus.com>
97
98 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
99 fractional type, so that quiet NaN's aren't treated like
100 Infinities.
101
102Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
103
104 * table.c (table_open): For cygwin hosts, we need to use the
105 return value from the read routine as the number of bytes to
106 process. This apparently is due to text-mode vs binary-mode. If
107 the mounts are done text-mode, then the size returnedby fstat()
108 may be different than the number of bytes "read" in text mode.
109
110Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
111
112 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

129 * configure: Regenerate.
130 * emul_{netbsd,unix}.c (toplevel): No longer try to include
131 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
132
133Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
134
135 * Makefile.in: The run target depended on a target psim$(EXEEXT),
136 but there was no such target, only plain psim. So I changed the
137 run target to depend on psim.
138
139Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
140
141 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
142 now defined in ../common/aclocal.m4, and the double definition causes
143 problems with AC_SUBST of EXEEXT.

499 max iterations exceeded.
500
501 * gen-idecode.c: Re-work the table lookup code so that it assumes
502 that the entry is a leaf by default. Simplify the boolean table
503 entry code so that it involves a mask + test instead of shift +
504 shift + mask + test.
505
506 * gen-idecode.c: Correct generated igen body so that it no drops
507 or doubles clock interrupts.
508
509

542Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
543
544 * When performance monitoring is disabled, it is still possible to
545 determine the simulation speed by looking at the number of elapsed
546 ticks recorded by the event queue.
547
548 * psim.c (psim_write_register, psim_read_register): Force the cpu
549 to zero when it is either of `-1' or `nr_cpus'. In both cases the
550 next cpu would be zero any way.
551
552 * mon.c (mon_print_info): If possible, print the system cycle
553 performance. This is an indication of the number of instructions
554 per second.
555
556Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
557
558 * The code to allow an event queue to be updated during a signal
559 was missing. For main.c, a cntrl-c simulation termination wasn't
560 handled cleanly.
561
562 * The simulation would not correctly restart if an event requested
563 that the simulation be halted.
564
565 * psim.c (psim_options): Add hack to -i option to optionally
566 include a level vis -i2.
567 (psim_usage): Document.

579 the processing state when processing has started. Adjust code
580 so that it is tolerant of halts.
581 (event_queue_init): Start the event queue out with processing
582 false.
583 (event_queue_tick): Check that processing isn't still being
584 performed.
585
586 * gen-idecode.c (print_run_until_stop_body): Call
587 event_queue_process_events to clear possibly pending events before
588 starting a simulation run. Re-arange main loop so that simulator

594
595Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
596
597 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
598 RA. Based on instruction frequency stats, expand additional
599 instructions.
600 * ppc-instructions: Change all `RA == 0' to RA_is_0.
601
602 * ppc-opcode-stupid: Move all but the basic table in -complex into
603 here. Update to new format.
604
605 * Makefile.in (tmp-defines): New target. Force defines.h to always
606 be built. Hence get ppc-opcode-goto to build.
607
608Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
609

611 Implement.
612
613Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
614
615 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
616 to be initialized independant of the rest of the simulation
617 initalization. Otherwize a trace option explictly set from gdb
618 could be overridden by hw_trace.
619
620 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
621
622 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
623 debug.c. It could be much simpler.
624
625Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
626
627 * Some devices support removable media. Add hooks to the disk

658
659 * For expressions like (RA == 0) that are entered in to the cache
660 as RA_is_0. If possible generate the result of the expression so
661 that the compiler gets a better chance of eliminating dead
662 branches.
663
664 * gen-icache.c (print_icache_extraction): For a cache entry of
665 the form <name>_is_<const> where it is a boolean field, generate

668 then generating corresponding definitions.
669
670 * gen-icache.c (print_icache_struct): If there is no cache, do not
671 output expressions in idecode.h file.
672
673 * gen-icache.c (print_icache_body): Output them here.

679
680Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
681
682 * The code that put values in and extracted values from the cache
683 was too compilicated. The cache table did not allow values to be
684 computed from cache entries. #defines could only be used when a
685 cache was present, remove the restriction.
686
687 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
688 scratch variable is defined when a cache entry is beinf

701
702 * gen-semantics.c (print_c_semantic): Update use.
703 * gen-idecode.c (print_jump_insn): Update use.
704 * gen-icache.c (print_icache_function): Update use.

706 * igen.c (main): Change 'R' option so that it does not force the
707 cache.
708
709 * configure.in (enable-sim-icache): Clarify description. Make
710 #define one of the defaults regardless of the cache. Probably
711 should revamp and add a separate option.

724
725 * The cap object was retaining a reference to the instance of a
726 device after it was deleted. Instead add and remove cap's from the
727 cap db as they are created and deleted. This ensuring that a
728 capibility is only used during the lifetime of the corresponding
729 object.
730
731 * cap.h, cap.c: Correct cap type - was signed32 should be
732 signed_cell.
733
734 * cap.c (cap_add, cap_remove): New methods for cap object that
735 allow the explicit addition and removal of internal objects that
736 the cap knows about.
737
738 * cap.c (cap_init): Rewrite. Verify that the only objects
739 remaining in the cap data base are those that were entered first.
740 Thse objects will be the permenant ones.

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

1989
1990 * std-config.h (SEMANTICS_INLINE): By default, mask out the

2041 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2042 same as cpu.[hc].
2043
2044 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2045 name for a lable and then branch to it.
2046
2047 * ppc-instructions (convert_to_integer, Floating Round to
2048 Single-Precision, Floating Convert from Integer Doubleword): Use
2049 LABEL and GOTO instead of the recently added switch statements.

2075
2076Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>

2120 * std-config.h: Change psim.c so that it isn't inlined (as this is
2121 no longer needed).
2122
2123 * psim.c (run_until_stop): Delete the old run_until_stop function
2124 instead calling the idecode_run and idecode_run_until_stop
2125 functions that gen-idecode.c is now creating.

2191
2192 * configure.in: New option --enable-sim-line-nr (default enabled).
