3 * events.c (event_queue_process): Call update_time_from_event
4 every time an event is removed from the queue.
5 (update_time_from_event): Delete assertion that a negative

13 (update_time_from_event): Trace full event queue.
15 2000-03-25 Geoff Keating <geoffk@cygnus.com>
17 * ppc-instructions (Disabled_Exponent_Underflow): Increment
18 the exponent when denormalizing.
20 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
22 * configure: Regenerated to track ../common/aclocal.m4 changes.
24 1999-05-08 Felix Lee <flee@cygnus.com>
26 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
27 * configure: Regenerated to track ../common/aclocal.m4 changes.
29 1999-04-02 Keith Seitz <keiths@cygnus.com>
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.
37 1999-02-22 Jim Lemke <jlemke@cygnus.com>
39 * dc-complex: Force expansion on all bits of field BO.
40 Previously, the least-significant (prediction) bit was ignored.

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

45 * interrupts.c (program_interrupt): Added handling for above interrupt.
47 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
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
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
72 1999-01-22 Jim Lemke <jlemke@cygnus.com>
74 * igen.c(gen_semantics_[ch]): setup/use of new option

78 psim.c(is_num - added, psim_options): Parse and init new option.
79 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
81 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
83 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

99 fractional type, so that quiet NaN's aren't treated like
102 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
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.
110 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
112 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

123 * sim_calls.c (sim_fetch_register, sim_store_register):
124 return zero when nothing to do.
126 1998-06-26 Michael Meissner <meissner@cygnus.com>
128 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
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.
133 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
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.
139 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
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.

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.
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.
552 * mon.c (mon_print_info): If possible, print the system cycle
553 performance. This is an indication of the number of instructions
556 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
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
562 * The simulation would not correctly restart if an event requested
563 that the simulation be halted.
565 * psim.c (psim_options): Add hack to -i option to optionally
566 include a level vis -i2.
567 (psim_usage): Document.
569 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

580 so that it is tolerant of halts.
581 (event_queue_init): Start the event queue out with processing
583 (event_queue_tick): Check that processing isn't still being
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
589 is correctly restarted when an event halts the simulation.
591 * psim.c (psim_halt): Handle an event halting the simulation.
592 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
595 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

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.
620 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
622 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
623 debug.c. It could be much simpler.
625 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
627 * Some devices support removable media. Add hooks to the disk

680 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
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.
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
689 filled. Change the definition of a COMPUTE variable to be defined
690 when the cache entry is being used.
691 * gen-icache.c: Update.
693 * ld-cache.h, ld-cache.c: Change field names so that their meaning
694 is more obvious. old_name->field_name, new_name->derived_name.

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

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

706 * igen.c (main): Change 'R' option so that it does not force the
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.

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