915 are simply renaming functions, to permit use of XCONCAT2 in both
916 the macro name and the arguments in a use of such a definition.
918 2000-11-15 Jim Blandy <jimb@redhat.com>
920 * sim_calls.c: Doc fix.
921 (sim_fetch_register, sim_store_register): Call

956 1999-05-08 Felix Lee <flee@cygnus.com>
958 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
959 * configure: Regenerated to track ../common/aclocal.m4 changes.
961 1999-04-02 Keith Seitz <keiths@cygnus.com>

967 after the specified POLL_QUIT_INTERVAL.
969 1999-02-22 Jim Lemke <jlemke@cygnus.com>
971 * dc-complex: Force expansion on all bits of field BO.
972 Previously, the least-significant (prediction) bit was ignored.

979 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
981 Make the simulator compatible with the MPC750. It would be nicer
982 to make this a real multi-sim, but that's more work than we have
984 * emul_generic.c (emul_add_tree_options): Only require strict
985 alignment if it was explicitly requested at configuration time.
986 Don't make it the default for little-endian machines.
987 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
988 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
989 THRM2, THRM3): Plop in the MPC750 SPR registers.
990 (DABR): This is weird. This was HID5, but the PPC spec says this
991 should be DABR; why did some random processor use it for something
992 else? The HID5 entry dates back to the original checkin of the
993 simulator code in 1995, so remove it.
994 * sim_calls.c (register_names): Delete this; since the user can
995 now change GDB's list of register names dynamically, we can't
996 pretend there's a static mapping here.
997 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
998 function to get the register name. That ought to be accurate.
999 However, we're changing a compile-time dependency (using the
1000 REGISTER_NAMES macro) into a link- and run-time dependency
1001 (calling REGISTER_NAME, which happens to be a function call on the
1004 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1006 * igen.c(gen_semantics_[ch]): setup/use of new option

1030 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1031 fractional type, so that quiet NaN's aren't treated like
1034 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1036 * table.c (table_open): For cygwin hosts, we need to use the
1037 return value from the read routine as the number of bytes to
1038 process. This apparently is due to text-mode vs binary-mode. If
1039 the mounts are done text-mode, then the size returnedby fstat()
1040 may be different than the number of bytes "read" in text mode.
1042 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1044 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1413 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1414 works for normal and boolean table entries.
1416 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1477 determine the simulation speed by looking at the number of elapsed
1478 ticks recorded by the event queue.
1480 * psim.c (psim_write_register, psim_read_register): Force the cpu
1481 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1482 next cpu would be zero any way.
1484 * mon.c (mon_print_info): If possible, print the system cycle
1485 performance. This is an indication of the number of instructions
1488 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1490 * The code to allow an event queue to be updated during a signal
1491 was missing. For main.c, a cntrl-c simulation termination wasn't
1494 * The simulation would not correctly restart if an event requested
1495 that the simulation be halted.
1497 * psim.c (psim_options): Add hack to -i option to optionally
1498 include a level vis -i2.
1499 (psim_usage): Document.
1501 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1518 * gen-idecode.c (print_run_until_stop_body): Call
1519 event_queue_process_events to clear possibly pending events before
1520 starting a simulation run. Re-arange main loop so that simulator
1521 is correctly restarted when an event halts the simulation.
1523 * psim.c (psim_halt): Handle an event halting the simulation.
1524 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1527 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1535 here. Update to new format.

1547 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1548 to be initialized independant of the rest of the simulation
1549 initalization. Otherwize a trace option explictly set from gdb
1550 could be overridden by hw_trace.
1552 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1554 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1555 debug.c. It could be much simpler.
1557 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1559 * Some devices support removable media. Add hooks to the disk

1573 string array - use the first entry for the initial file image.
1575 * tree.c (print_string_aray_property): New function - print a
