SS		 151999-04-02 Keith Seitz <keiths@cygnus.com>
16
17 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
18 the frequency at which the poll_quit callback is called.
19 (poll_quit_count): New global.
20 (sim_io_poll_quit): Only call the poll_quit callback
21 after the specified POLL_QUIT_INTERVAL.
22
231999-02-22 Jim Lemke <jlemke@cygnus.com>
24
25 * dc-complex: Force expansion on all bits of field BO.
26 Previously, the least-significant (prediction) bit was ignored.
27 * ppc-instructions (conditional branches): Implement mpc860c0 option.
28 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
29 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
30 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".

35 Make the simulator compatible with the MPC750. It would be nicer
36 to make this a real multi-sim, but that's more work than we have
37 time for.
38 * emul_generic.c (emul_add_tree_options): Only require strict
39 alignment if it was explicitly requested at configuration time.
40 Don't make it the default for little-endian machines.
41 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
42 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
43 THRM2, THRM3): Plop in the MPC750 SPR registers.
44 (DABR): This is weird. This was HID5, but the PPC spec says this
45 should be DABR; why did some random processor use it for something
46 else? The HID5 entry dates back to the original checkin of the
47 simulator code in 1995, so remove it.
48 * sim_calls.c (register_names): Delete this; since the user can
49 now change GDB's list of register names dynamically, we can't
50 pretend there's a static mapping here.
51 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
52 function to get the register name. That ought to be accurate.
53 However, we're changing a compile-time dependency (using the
54 REGISTER_NAMES macro) into a link- and run-time dependency
55 (calling REGISTER_NAME, which happens to be a function call on the
56 PPC).
57
581999-01-22 Jim Lemke <jlemke@cygnus.com>
59
60 * igen.c(gen_semantics_[ch]): setup/use of new option
61 (-o mpc860c0[=n]).
62 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
63 ppc-instructions(the four branch insn groups): detect problematic br's.
64 psim.c(is_num - added, psim_options): Parse and init new option.
65 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
66
671998-12-01 Ken Raeburn <raeburn@cygnus.com>
68
69 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.
70
71Fri Nov 20 12:17:28 1998 Andrew Cagney <cagney@b1.cygnus.com>
72
73 * main.c (sim_io_poll_quit): Stub function.
74
75 * events.c (SIM_EVENTS_POLL_RATE): Define.

78
79 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
80 poll the external environment.
81
821998-11-19 Michael Meissner <meissner@cygnus.com>
83
84 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
85 fractional type, so that quiet NaN's aren't treated like
86 Infinities.
87
88Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
89
90 * table.c (table_open): For cygwin hosts, we need to use the
91 return value from the read routine as the number of bytes to
92 process. This apparently is due to text-mode vs binary-mode. If
93 the mounts are done text-mode, then the size returnedby fstat()
94 may be different than the number of bytes "read" in text mode.
95
96Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
97
98 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

118
119Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
120
121 * Makefile.in: The run target depended on a target psim$(EXEEXT),
122 but there was no such target, only plain psim. So I changed the
123 run target to depend on psim.
124
125Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
126
127 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
128 now defined in ../common/aclocal.m4, and the double definition causes
129 problems with AC_SUBST of EXEEXT.

484 (psim_max_iterations_exceeded): New function, abort simulation if
485 max iterations exceeded.
486
487 * gen-idecode.c: Re-work the table lookup code so that it assumes
488 that the entry is a leaf by default. Simplify the boolean table
489 entry code so that it involves a mask + test instead of shift +
490 shift + mask + test.
491
492 * gen-idecode.c: Correct generated igen body so that it no drops
493 or doubles clock interrupts.
494
495

528Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
529
530 * When performance monitoring is disabled, it is still possible to
531 determine the simulation speed by looking at the number of elapsed
532 ticks recorded by the event queue.
533
534 * psim.c (psim_write_register, psim_read_register): Force the cpu
535 to zero when it is either of `-1' or `nr_cpus'. In both cases the
536 next cpu would be zero any way.
537
538 * mon.c (mon_print_info): If possible, print the system cycle
539 performance. This is an indication of the number of instructions
540 per second.
541
542Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
543
544 * The code to allow an event queue to be updated during a signal
545 was missing. For main.c, a cntrl-c simulation termination wasn't
546 handled cleanly.
547
548 * The simulation would not correctly restart if an event requested
549 that the simulation be halted.
550
551 * psim.c (psim_options): Add hack to -i option to optionally
552 include a level vis -i2.
553 (psim_usage): Document.

565 the processing state when processing has started. Adjust code
566 so that it is tolerant of halts.
567 (event_queue_init): Start the event queue out with processing
568 false.
569 (event_queue_tick): Check that processing isn't still being
570 performed.
571
572 * gen-idecode.c (print_run_until_stop_body): Call
573 event_queue_process_events to clear possibly pending events before
574 starting a simulation run. Re-arange main loop so that simulator
575 is correctly restarted when an event halts the simulation.

578 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
579 reworked idecode.
580
581Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
582
583 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
584 RA. Based on instruction frequency stats, expand additional
585 instructions.
586 * ppc-instructions: Change all `RA == 0' to RA_is_0.
587
588 * ppc-opcode-stupid: Move all but the basic table in -complex into
589 here. Update to new format.
590
591 * Makefile.in (tmp-defines): New target. Force defines.h to always
592 be built. Hence get ppc-opcode-goto to build.
593
594Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
595

597 Implement.
598
599Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
600
601 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
602 to be initialized independant of the rest of the simulation
603 initalization. Otherwize a trace option explictly set from gdb
604 could be overridden by hw_trace.
605
606 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
607
608 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
609 debug.c. It could be much simpler.
610
611Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
612
613 * Some devices support removable media. Add hooks to the disk

630 string array.
631 (print_properties): Adjust.
632 (print_string): Write a string, handling double quotes.

644
645 * For expressions like (RA == 0) that are entered in to the cache
646 as RA_is_0. If possible generate the result of the expression so
647 that the compiler gets a better chance of eliminating dead
648 branches.
649
650 * gen-icache.c (print_icache_extraction): For a cache entry of
651 the form <name>_is_<const> where it is a boolean field, generate

653 (print_icache_body): Remove code that was looking for *_is_0 and
654 then generating corresponding definitions.
655
656 * gen-icache.c (print_icache_struct): If there is no cache, do not
657 output expressions in idecode.h file.
658
659 * gen-icache.c (print_icache_body): Output them here.

664 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
665
666Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
667
668 * The code that put values in and extracted values from the cache
669 was too compilicated. The cache table did not allow values to be
670 computed from cache entries. #defines could only be used when a
671 cache was present, remove the restriction.
672
673 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
674 scratch variable is defined when a cache entry is beinf
675 filled. Change the definition of a COMPUTE variable to be defined

687
688 * gen-semantics.c (print_c_semantic): Update use.
689 * gen-idecode.c (print_jump_insn): Update use.
690 * gen-icache.c (print_icache_function): Update use.
691
692 * igen.c (main): Change 'R' option so that it does not force the
693 cache.
694
695 * configure.in (enable-sim-icache): Clarify description. Make
696 #define one of the defaults regardless of the cache. Probably
697 should revamp and add a separate option.
698

710
711 * The cap object was retaining a reference to the instance of a
712 device after it was deleted. Instead add and remove cap's from the
713 cap db as they are created and deleted. This ensuring that a
714 capibility is only used during the lifetime of the corresponding
715 object.
716
717 * cap.h, cap.c: Correct cap type - was signed32 should be
718 signed_cell.
719
720 * cap.c (cap_add, cap_remove): New methods for cap object that
721 allow the explicit addition and removal of internal objects that
722 the cap knows about.
723
724 * cap.c (cap_init): Rewrite. Verify that the only objects
725 remaining in the cap data base are those that were entered first.
726 Thse objects will be the permenant ones.

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

1975
1976 * std-config.h (SEMANTICS_INLINE): By default, mask out the
1977 inlining of semantic functions from DEFAULT_INLINE. Almost all

2026 modules that include it.
2027 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2028 same as cpu.[hc].
2029
2030 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2031 name for a lable and then branch to it.
2032
2033 * ppc-instructions (convert_to_integer, Floating Round to
2034 Single-Precision, Floating Convert from Integer Doubleword): Use
2035 LABEL and GOTO instead of the recently added switch statements.

2061
2062Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>

2105
2106 * std-config.h: Change psim.c so that it isn't inlined (as this is
2107 no longer needed).
2108
2109 * psim.c (run_until_stop): Delete the old run_until_stop function
2110 instead calling the idecode_run and idecode_run_until_stop
2111 functions that gen-idecode.c is now creating.

2177
2178 * configure.in: New option --enable-sim-line-nr (default enabled).
