30 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
32 * table.c (table_open): For cygwin hosts, we need to use the
33 return value from the read routine as the number of bytes to
34 process. This apparently is due to text-mode vs binary-mode. If
35 the mounts are done text-mode, then the size returnedby fstat()
36 may be different than the number of bytes "read" in text mode.

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

473 determine the simulation speed by looking at the number of elapsed
474 ticks recorded by the event queue.
476 * psim.c (psim_write_register, psim_read_register): Force the cpu
477 to zero when it is either of `-1' or `nr_cpus'. In both cases the
478 next cpu would be zero any way.
480 * mon.c (mon_print_info): If possible, print the system cycle
481 performance. This is an indication of the number of instructions
484 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
486 * The code to allow an event queue to be updated during a signal
487 was missing. For main.c, a cntrl-c simulation termination wasn't
490 * The simulation would not correctly restart if an event requested
491 that the simulation be halted.
493 * psim.c (psim_options): Add hack to -i option to optionally
494 include a level vis -i2.
495 (psim_usage): Document.

514 * gen-idecode.c (print_run_until_stop_body): Call
515 event_queue_process_events to clear possibly pending events before
516 starting a simulation run. Re-arange main loop so that simulator
517 is correctly restarted when an event halts the simulation.
519 * psim.c (psim_halt): Handle an event halting the simulation.
520 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
523 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

531 here. Update to new format.

543 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
544 to be initialized independant of the rest of the simulation
545 initalization. Otherwize a trace option explictly set from gdb
546 could be overridden by hw_trace.
548 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
550 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
551 debug.c. It could be much simpler.
553 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
555 * Some devices support removable media. Add hooks to the disk
