1051 simulator code in 1995, so remove it.
1052 * sim_calls.c (register_names): Delete this; since the user can
1053 now change GDB's list of register names dynamically, we can't
1054 pretend there's a static mapping here.
1055 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1056 function to get the register name. That ought to be accurate.
1057 However, we're changing a compile-time dependency (using the
1058 REGISTER_NAMES macro) into a link- and run-time dependency
1059 (calling REGISTER_NAME, which happens to be a function call on the
1062 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1064 * igen.c(gen_semantics_[ch]): setup/use of new option
1066 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
1067 ppc-instructions(the four branch insn groups): detect problematic br's.
1068 psim.c(is_num - added, psim_options): Parse and init new option.
1069 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
1071 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
1073 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

1092 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1094 * table.c (table_open): For cygwin hosts, we need to use the
1095 return value from the read routine as the number of bytes to
1096 process. This apparently is due to text-mode vs binary-mode. If
1097 the mounts are done text-mode, then the size returnedby fstat()
1098 may be different than the number of bytes "read" in text mode.
1100 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

1123 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1125 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1126 but there was no such target, only plain psim. So I changed the
1127 run target to depend on psim.

1538 * psim.c (psim_write_register, psim_read_register): Force the cpu
1539 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1540 next cpu would be zero any way.
1542 * mon.c (mon_print_info): If possible, print the system cycle
1543 performance. This is an indication of the number of instructions
1546 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1548 * The code to allow an event queue to be updated during a signal
1549 was missing. For main.c, a cntrl-c simulation termination wasn't

1553 that the simulation be halted.

1576 * gen-idecode.c (print_run_until_stop_body): Call
1577 event_queue_process_events to clear possibly pending events before
1578 starting a simulation run. Re-arange main loop so that simulator

1605 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1606 to be initialized independant of the rest of the simulation
1607 initalization. Otherwize a trace option explictly set from gdb
1608 could be overridden by hw_trace.
1610 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1612 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

1673 was too compilicated. The cache table did not allow values to be
1674 computed from cache entries. #defines could only be used when a
1675 cache was present, remove the restriction.
1677 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1678 scratch variable is defined when a cache entry is beinf
1679 filled. Change the definition of a COMPUTE variable to be defined
1680 when the cache entry is being used.
1681 * gen-icache.c: Update.

1699 * configure.in (enable-sim-icache): Clarify description. Make
1700 #define one of the defaults regardless of the cache. Probably
1701 should revamp and add a separate option.
