3 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
4 fractional type, so that quiet NaN's aren't treated like
7 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
9 * table.c (table_open): For cygwin hosts, we need to use the return value
10 from the read routine as the number of bytes to process. This apparently
11 is due to text-mode vs binary-mode. If the mounts are done text-mode,
12 then the size returnedby fstat() may be different than the number of
13 bytes "read" in text mode.

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

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

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

521 to be initialized independant of the rest of the simulation
522 initalization. Otherwize a trace option explictly set from gdb
523 could be overridden by hw_trace.
525 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
527 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
528 debug.c. It could be much simpler.
530 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
532 * Some devices support removable media. Add hooks to the disk

2153 * configure.in: Adjust filter flag so that default includes 32bit
