1009 function to get the register name. That ought to be accurate.

1042 fractional type, so that quiet NaN's aren't treated like
1045 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1047 * table.c (table_open): For cygwin hosts, we need to use the
1048 return value from the read routine as the number of bytes to
1049 process. This apparently is due to text-mode vs binary-mode. If
1050 the mounts are done text-mode, then the size returnedby fstat()
1051 may be different than the number of bytes "read" in text mode.
1053 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

1076 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1078 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1079 but there was no such target, only plain psim. So I changed the
1080 run target to depend on psim.

1356 Wed Feb 12 19:33:45 1997 Andrew Cagney <cagney@phydeaux.cygnus.com>
1358 * Many of the ppc-opcode-* files are identical baring the type of

1409 (device_add_ihandle_runtime_property): Update.

1418 Augment each extracted field with a comment citing the codes

1422 Tue Feb 4 17:44:51 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1424 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1425 works for normal and boolean table entries.
1427 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1428 valid. Handle this just like *_{read,write}_register now handles

1447 shift + mask + test.
1449 * gen-idecode.c: Correct generated igen body so that it no drops
1450 or doubles clock interrupts.
1453 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1455 * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to
1458 * configure.in (sim_callback, sim_targ_vals): Set sim_targ_valls
1459 if common callback is present.
1461 Wed Jan 29 12:32:41 1997 Michael Meissner <meissner@tiktok.cygnus.com>
1463 * configure.in (sim_callback): If the gdb is post 4.16, configure

1488 determine the simulation speed by looking at the number of elapsed
1489 ticks recorded by the event queue.
1491 * psim.c (psim_write_register, psim_read_register): Force the cpu
1492 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1493 next cpu would be zero any way.
1495 * mon.c (mon_print_info): If possible, print the system cycle
1496 performance. This is an indication of the number of instructions
1499 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1501 * The code to allow an event queue to be updated during a signal
1502 was missing. For main.c, a cntrl-c simulation termination wasn't
1505 * The simulation would not correctly restart if an event requested
1506 that the simulation be halted.
1508 * psim.c (psim_options): Add hack to -i option to optionally
1509 include a level vis -i2.
1510 (psim_usage): Document.
1512 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1513 cntrl-c occures schedule an event to halt the simulation.
1514 (main): Catch CNTRL-C signals with the function cntrl_c.
1516 * events.c (event_queue_process): Mask interrupts while
1517 manipulating the async event queue.
1518 (event_queue_init): Ditto.
1519 (event_queue_schedule_after_signal): Ditto.
1521 * events.c (event_queue_process): Mark the event queue as being in
1522 the processing state when processing has started. Adjust code

1526 (event_queue_tick): Check that processing isn't still being
1529 * gen-idecode.c (print_run_until_stop_body): Call
1530 event_queue_process_events to clear possibly pending events before
1531 starting a simulation run. Re-arange main loop so that simulator
1532 is correctly restarted when an event halts the simulation.
1534 * psim.c (psim_halt): Handle an event halting the simulation.
1535 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1538 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1540 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1541 RA. Based on instruction frequency stats, expand additional
1543 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1545 * ppc-opcode-stupid: Move all but the basic table in -complex into
1546 here. Update to new format.
1548 * Makefile.in (tmp-defines): New target. Force defines.h to always
1549 be built. Hence get ppc-opcode-goto to build.
1551 Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1553 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1556 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1558 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1559 to be initialized independant of the rest of the simulation
1560 initalization. Otherwize a trace option explictly set from gdb
1561 could be overridden by hw_trace.
1563 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1565 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1566 debug.c. It could be much simpler.
1568 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1570 * Some devices support removable media. Add hooks to the disk
1571 device so that it supports this.
1573 * device.c (device_add_string_array_property,
