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

34 * Makefile.in: The run target depended on a target psim$(EXEEXT),
35 but there was no such target, only plain psim. So I changed the
36 run target to depend on psim.

445 ticks recorded by the event queue.
447 * psim.c (psim_write_register, psim_read_register): Force the cpu
448 to zero when it is either of `-1' or `nr_cpus'. In both cases the
449 next cpu would be zero any way.

452 performance. This is an indication of the number of instructions
455 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
457 * The code to allow an event queue to be updated during a signal
458 was missing. For main.c, a cntrl-c simulation termination wasn't

491 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
494 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

515 to be initialized independant of the rest of the simulation
516 initalization. Otherwize a trace option explictly set from gdb

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

2146 * Makefile.in (filter.o): Adjust
2147 * configure.in: Adjust filter flag so that default includes 32bit
