519 * ppc-instructions (Disabled_Exponent_Underflow): Increment
520 the exponent when denormalizing.
522 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
524 * configure: Regenerated to track ../common/aclocal.m4 changes.
526 1999-05-08 Felix Lee <flee@cygnus.com>
528 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
529 * configure: Regenerated to track ../common/aclocal.m4 changes.
531 1999-04-02 Keith Seitz <keiths@cygnus.com>
533 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
534 the frequency at which the poll_quit callback is called.
535 (poll_quit_count): New global.
536 (sim_io_poll_quit): Only call the poll_quit callback
537 after the specified POLL_QUIT_INTERVAL.
539 1999-02-22 Jim Lemke <jlemke@cygnus.com>
541 * dc-complex: Force expansion on all bits of field BO.
542 Previously, the least-significant (prediction) bit was ignored.
543 * ppc-instructions (conditional branches): Implement mpc860c0 option.
544 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.

549 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
551 Make the simulator compatible with the MPC750. It would be nicer
552 to make this a real multi-sim, but that's more work than we have
554 * emul_generic.c (emul_add_tree_options): Only require strict
555 alignment if it was explicitly requested at configuration time.
556 Don't make it the default for little-endian machines.
557 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
558 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
559 THRM2, THRM3): Plop in the MPC750 SPR registers.
560 (DABR): This is weird. This was HID5, but the PPC spec says this
561 should be DABR; why did some random processor use it for something
562 else? The HID5 entry dates back to the original checkin of the
563 simulator code in 1995, so remove it.
564 * sim_calls.c (register_names): Delete this; since the user can
565 now change GDB's list of register names dynamically, we can't
566 pretend there's a static mapping here.
567 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
568 function to get the register name. That ought to be accurate.
569 However, we're changing a compile-time dependency (using the
570 REGISTER_NAMES macro) into a link- and run-time dependency
571 (calling REGISTER_NAME, which happens to be a function call on the
574 1999-01-22 Jim Lemke <jlemke@cygnus.com>

601 fractional type, so that quiet NaN's aren't treated like
604 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
606 * table.c (table_open): For cygwin hosts, we need to use the
607 return value from the read routine as the number of bytes to
608 process. This apparently is due to text-mode vs binary-mode. If
609 the mounts are done text-mode, then the size returnedby fstat()
610 may be different than the number of bytes "read" in text mode.
612 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
614 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

631 * configure: Regenerate.
632 * emul_{netbsd,unix}.c (toplevel): No longer try to include
633 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
635 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
637 * Makefile.in: The run target depended on a target psim$(EXEEXT),
638 but there was no such target, only plain psim. So I changed the
639 run target to depend on psim.
641 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
643 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
644 now defined in ../common/aclocal.m4, and the double definition causes
645 problems with AC_SUBST of EXEEXT.

1050 * psim.c (psim_write_register, psim_read_register): Force the cpu
1051 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1052 next cpu would be zero any way.
1054 * mon.c (mon_print_info): If possible, print the system cycle
1055 performance. This is an indication of the number of instructions
1058 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1060 * The code to allow an event queue to be updated during a signal
1061 was missing. For main.c, a cntrl-c simulation termination wasn't
1064 * The simulation would not correctly restart if an event requested
1065 that the simulation be halted.
1067 * psim.c (psim_options): Add hack to -i option to optionally
1068 include a level vis -i2.
1069 (psim_usage): Document.
1071 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1088 * gen-idecode.c (print_run_until_stop_body): Call
1089 event_queue_process_events to clear possibly pending events before

1117 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1118 to be initialized independant of the rest of the simulation
1119 initalization. Otherwize a trace option explictly set from gdb
1120 could be overridden by hw_trace.
1122 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1124 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1125 debug.c. It could be much simpler.

1184 * The code that put values in and extracted values from the cache
1185 was too compilicated. The cache table did not allow values to be
1186 computed from cache entries. #defines could only be used when a
1187 cache was present, remove the restriction.
1189 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1190 scratch variable is defined when a cache entry is beinf
1191 filled. Change the definition of a COMPUTE variable to be defined
1192 when the cache entry is being used.
1193 * gen-icache.c: Update.
1195 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1208 * igen.c (main): Change 'R' option so that it does not force the
1211 * configure.in (enable-sim-icache): Clarify description. Make
1212 #define one of the defaults regardless of the cache. Probably
1213 should revamp and add a separate option.
