18 * events.c (event_queue_process): Call update_time_from_event
19 every time an event is removed from the queue.
20 (update_time_from_event): Delete assertion that a negative
21 time_from_event implies an empty event queue.

25 * interrupts.c (deliver_hardware_interrupt): Print time trace in

28 (update_time_from_event): Trace full event queue.
30 2000-03-25 Geoff Keating <geoffk@cygnus.com>
32 * ppc-instructions (Disabled_Exponent_Underflow): Increment
33 the exponent when denormalizing.
35 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
37 * configure: Regenerated to track ../common/aclocal.m4 changes.
39 1999-05-08 Felix Lee <flee@cygnus.com>
41 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
42 * configure: Regenerated to track ../common/aclocal.m4 changes.
44 1999-04-02 Keith Seitz <keiths@cygnus.com>
46 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
47 the frequency at which the poll_quit callback is called.
48 (poll_quit_count): New global.
49 (sim_io_poll_quit): Only call the poll_quit callback
50 after the specified POLL_QUIT_INTERVAL.
52 1999-02-22 Jim Lemke <jlemke@cygnus.com>
54 * dc-complex: Force expansion on all bits of field BO.
55 Previously, the least-significant (prediction) bit was ignored.

57 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
58 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

60 * interrupts.c (program_interrupt): Added handling for above interrupt.
62 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
64 Make the simulator compatible with the MPC750. It would be nicer
65 to make this a real multi-sim, but that's more work than we have
67 * emul_generic.c (emul_add_tree_options): Only require strict
68 alignment if it was explicitly requested at configuration time.
69 Don't make it the default for little-endian machines.
70 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
71 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
72 THRM2, THRM3): Plop in the MPC750 SPR registers.
73 (DABR): This is weird. This was HID5, but the PPC spec says this
74 should be DABR; why did some random processor use it for something
75 else? The HID5 entry dates back to the original checkin of the
76 simulator code in 1995, so remove it.
77 * sim_calls.c (register_names): Delete this; since the user can
78 now change GDB's list of register names dynamically, we can't
79 pretend there's a static mapping here.
80 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
81 function to get the register name. That ought to be accurate.
82 However, we're changing a compile-time dependency (using the
83 REGISTER_NAMES macro) into a link- and run-time dependency
84 (calling REGISTER_NAME, which happens to be a function call on the
87 1999-01-22 Jim Lemke <jlemke@cygnus.com>

93 psim.c(is_num - added, psim_options): Parse and init new option.
94 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
96 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
98 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

114 fractional type, so that quiet NaN's aren't treated like
117 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
119 * table.c (table_open): For cygwin hosts, we need to use the
120 return value from the read routine as the number of bytes to
121 process. This apparently is due to text-mode vs binary-mode. If
122 the mounts are done text-mode, then the size returnedby fstat()
123 may be different than the number of bytes "read" in text mode.
125 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
127 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

143 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
144 * configure: Regenerate.
145 * emul_{netbsd,unix}.c (toplevel): No longer try to include
146 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
148 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
150 * Makefile.in: The run target depended on a target psim$(EXEEXT),
151 but there was no such target, only plain psim. So I changed the
152 run target to depend on psim.
154 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
156 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
157 now defined in ../common/aclocal.m4, and the double definition causes
158 problems with AC_SUBST of EXEEXT.

496 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
497 works for normal and boolean table entries.
499 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

557 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
559 * When performance monitoring is disabled, it is still possible to
560 determine the simulation speed by looking at the number of elapsed
561 ticks recorded by the event queue.
563 * psim.c (psim_write_register, psim_read_register): Force the cpu
564 to zero when it is either of `-1' or `nr_cpus'. In both cases the
565 next cpu would be zero any way.
567 * mon.c (mon_print_info): If possible, print the system cycle
568 performance. This is an indication of the number of instructions
571 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
573 * The code to allow an event queue to be updated during a signal
574 was missing. For main.c, a cntrl-c simulation termination wasn't
577 * The simulation would not correctly restart if an event requested
578 that the simulation be halted.
580 * psim.c (psim_options): Add hack to -i option to optionally
581 include a level vis -i2.
582 (psim_usage): Document.

596 (event_queue_init): Start the event queue out with processing
598 (event_queue_tick): Check that processing isn't still being
601 * gen-idecode.c (print_run_until_stop_body): Call
602 event_queue_process_events to clear possibly pending events before
603 starting a simulation run. Re-arange main loop so that simulator
604 is correctly restarted when an event halts the simulation.
606 * psim.c (psim_halt): Handle an event halting the simulation.
607 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
610 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

630 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
631 to be initialized independant of the rest of the simulation
632 initalization. Otherwize a trace option explictly set from gdb
633 could be overridden by hw_trace.
635 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
637 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
638 debug.c. It could be much simpler.
640 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

695 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
697 * The code that put values in and extracted values from the cache
698 was too compilicated. The cache table did not allow values to be
699 computed from cache entries. #defines could only be used when a
700 cache was present, remove the restriction.
702 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
703 scratch variable is defined when a cache entry is beinf
704 filled. Change the definition of a COMPUTE variable to be defined
705 when the cache entry is being used.
706 * gen-icache.c: Update.
708 * ld-cache.h, ld-cache.c: Change field names so that their meaning
709 is more obvious. old_name->field_name, new_name->derived_name.

712 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
713 different types of cache code - put into cache, extract from
714 cache, no cache - an explicit argument to print_icache_body.

717 * gen-semantics.c (print_c_semantic): Update use.
718 * gen-idecode.c (print_jump_insn): Update use.

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

730 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
