1 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
3 * sim-endian.h: Don't have parameters on macro definitions which
4 are simply renaming functions, to permit use of XCONCAT2 in both
5 the macro name and the arguments in a use of such a definition.
7 2000-11-15 Jim Blandy <jimb@redhat.com>
9 * sim_calls.c: Doc fix.
10 (sim_fetch_register, sim_store_register): Call
11 gdbarch_register_name directly, instead of going through
14 2000-10-24 Geoff Keating <geoffk@cygnus.com>

22 Fri Apr 28 15:59:27 2000 Andrew Cagney <cagney@b1.cygnus.com>
24 * events.c (event_queue_process): Call update_time_from_event
25 every time an event is removed from the queue.
26 (update_time_from_event): Delete assertion that a negative
27 time_from_event implies an empty event queue.
29 Fri Apr 28 15:53:54 2000 Andrew Cagney <cagney@b1.cygnus.com>
31 * interrupts.c (deliver_hardware_interrupt): Print time trace in
33 * events.c (event_queue_process): Cleanup trace message.
34 (update_time_from_event): Trace full event queue.
36 2000-03-25 Geoff Keating <geoffk@cygnus.com>
38 * ppc-instructions (Disabled_Exponent_Underflow): Increment
39 the exponent when denormalizing.
41 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
43 * configure: Regenerated to track ../common/aclocal.m4 changes.
45 1999-05-08 Felix Lee <flee@cygnus.com>
47 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
48 * configure: Regenerated to track ../common/aclocal.m4 changes.
50 1999-04-02 Keith Seitz <keiths@cygnus.com>
52 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
53 the frequency at which the poll_quit callback is called.
54 (poll_quit_count): New global.
55 (sim_io_poll_quit): Only call the poll_quit callback
56 after the specified POLL_QUIT_INTERVAL.
58 1999-02-22 Jim Lemke <jlemke@cygnus.com>
60 * dc-complex: Force expansion on all bits of field BO.
61 Previously, the least-significant (prediction) bit was ignored.

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

66 * interrupts.c (program_interrupt): Added handling for above interrupt.
68 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
70 Make the simulator compatible with the MPC750. It would be nicer
71 to make this a real multi-sim, but that's more work than we have
73 * emul_generic.c (emul_add_tree_options): Only require strict
74 alignment if it was explicitly requested at configuration time.
75 Don't make it the default for little-endian machines.
76 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
77 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
78 THRM2, THRM3): Plop in the MPC750 SPR registers.
79 (DABR): This is weird. This was HID5, but the PPC spec says this
80 should be DABR; why did some random processor use it for something
81 else? The HID5 entry dates back to the original checkin of the
82 simulator code in 1995, so remove it.
83 * sim_calls.c (register_names): Delete this; since the user can
84 now change GDB's list of register names dynamically, we can't
85 pretend there's a static mapping here.
86 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
87 function to get the register name. That ought to be accurate.
88 However, we're changing a compile-time dependency (using the
89 REGISTER_NAMES macro) into a link- and run-time dependency
90 (calling REGISTER_NAME, which happens to be a function call on the
93 1999-01-22 Jim Lemke <jlemke@cygnus.com>
95 * igen.c(gen_semantics_[ch]): setup/use of new option

99 psim.c(is_num - added, psim_options): Parse and init new option.
100 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
102 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
104 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

119 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
120 fractional type, so that quiet NaN's aren't treated like
123 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
125 * table.c (table_open): For cygwin hosts, we need to use the
126 return value from the read routine as the number of bytes to
127 process. This apparently is due to text-mode vs binary-mode. If
128 the mounts are done text-mode, then the size returnedby fstat()
129 may be different than the number of bytes "read" in text mode.
131 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
133 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

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

487 (device_add_ihandle_runtime_property): Update.

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

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

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

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

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

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

718 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
719 different types of cache code - put into cache, extract from

723 * gen-semantics.c (print_c_semantic): Update use.
724 * gen-idecode.c (print_jump_insn): Update use.

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

2269 * configure.in: Adjust filter flag so that default includes 32bit
