12 every time an event is removed from the queue.
13 (update_time_from_event): Delete assertion that a negative

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

30 * configure: Regenerated to track ../common/aclocal.m4 changes.
32 1999-05-08 Felix Lee <flee@cygnus.com>
34 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
35 * configure: Regenerated to track ../common/aclocal.m4 changes.
37 1999-04-02 Keith Seitz <keiths@cygnus.com>
39 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
40 the frequency at which the poll_quit callback is called.
41 (poll_quit_count): New global.
42 (sim_io_poll_quit): Only call the poll_quit callback
43 after the specified POLL_QUIT_INTERVAL.
45 1999-02-22 Jim Lemke <jlemke@cygnus.com>
47 * dc-complex: Force expansion on all bits of field BO.
48 Previously, the least-significant (prediction) bit was ignored.

51 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

53 * interrupts.c (program_interrupt): Added handling for above interrupt.
55 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
57 Make the simulator compatible with the MPC750. It would be nicer
58 to make this a real multi-sim, but that's more work than we have
60 * emul_generic.c (emul_add_tree_options): Only require strict
61 alignment if it was explicitly requested at configuration time.
62 Don't make it the default for little-endian machines.
63 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
64 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
65 THRM2, THRM3): Plop in the MPC750 SPR registers.
66 (DABR): This is weird. This was HID5, but the PPC spec says this
67 should be DABR; why did some random processor use it for something
68 else? The HID5 entry dates back to the original checkin of the
69 simulator code in 1995, so remove it.
70 * sim_calls.c (register_names): Delete this; since the user can
71 now change GDB's list of register names dynamically, we can't
72 pretend there's a static mapping here.
73 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
74 function to get the register name. That ought to be accurate.
75 However, we're changing a compile-time dependency (using the
76 REGISTER_NAMES macro) into a link- and run-time dependency
77 (calling REGISTER_NAME, which happens to be a function call on the
80 1999-01-22 Jim Lemke <jlemke@cygnus.com>

86 psim.c(is_num - added, psim_options): Parse and init new option.
87 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
89 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
91 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

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

132 return zero when nothing to do.
134 1998-06-26 Michael Meissner <meissner@cygnus.com>
136 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
137 * configure: Regenerate.
138 * emul_{netbsd,unix}.c (toplevel): No longer try to include
139 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
141 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
143 * Makefile.in: The run target depended on a target psim$(EXEEXT),
144 but there was no such target, only plain psim. So I changed the
145 run target to depend on psim.
147 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
149 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
150 now defined in ../common/aclocal.m4, and the double definition causes
151 problems with AC_SUBST of EXEEXT.

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

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

623 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
624 to be initialized independant of the rest of the simulation

626 could be overridden by hw_trace.
628 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
630 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
631 debug.c. It could be much simpler.
633 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

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

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

710 * gen-semantics.c (print_c_semantic): Update use.
711 * gen-idecode.c (print_jump_insn): Update use.

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

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