1060 * dc-complex: Force expansion on all bits of field BO.
1061 Previously, the least-significant (prediction) bit was ignored.
1062 * ppc-instructions (conditional branches): Implement mpc860c0 option.
1063 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
1064 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
1065 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
1066 * interrupts.c (program_interrupt): Added handling for above interrupt.
1068 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1070 Make the simulator compatible with the MPC750. It would be nicer
1071 to make this a real multi-sim, but that's more work than we have
1073 * emul_generic.c (emul_add_tree_options): Only require strict
1074 alignment if it was explicitly requested at configuration time.
1075 Don't make it the default for little-endian machines.
1076 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1077 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1078 THRM2, THRM3): Plop in the MPC750 SPR registers.
1079 (DABR): This is weird. This was HID5, but the PPC spec says this
1080 should be DABR; why did some random processor use it for something
1081 else? The HID5 entry dates back to the original checkin of the
1082 simulator code in 1995, so remove it.
1083 * sim_calls.c (register_names): Delete this; since the user can
1084 now change GDB's list of register names dynamically, we can't
1085 pretend there's a static mapping here.
1086 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1087 function to get the register name. That ought to be accurate.
1088 However, we're changing a compile-time dependency (using the
1089 REGISTER_NAMES macro) into a link- and run-time dependency
1090 (calling REGISTER_NAME, which happens to be a function call on the
1093 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1095 * igen.c(gen_semantics_[ch]): setup/use of new option
1097 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
1098 ppc-instructions(the four branch insn groups): detect problematic br's.
1099 psim.c(is_num - added, psim_options): Parse and init new option.
1100 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

1120 fractional type, so that quiet NaN's aren't treated like
1123 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1125 * table.c (table_open): For cygwin hosts, we need to use the
1126 return value from the read routine as the number of bytes to
1127 process. This apparently is due to text-mode vs binary-mode. If
1128 the mounts are done text-mode, then the size returnedby fstat()
1129 may be different than the number of bytes "read" in text mode.
1131 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1133 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1154 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1156 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1157 but there was no such target, only plain psim. So I changed the
1158 run target to depend on psim.
1160 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1162 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1163 now defined in ../common/aclocal.m4, and the double definition causes

1525 shift + mask + test.
1527 * gen-idecode.c: Correct generated igen body so that it no drops
1528 or doubles clock interrupts.

1566 determine the simulation speed by looking at the number of elapsed
1567 ticks recorded by the event queue.
1569 * psim.c (psim_write_register, psim_read_register): Force the cpu
1570 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1571 next cpu would be zero any way.
1573 * mon.c (mon_print_info): If possible, print the system cycle
1574 performance. This is an indication of the number of instructions
1577 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1579 * The code to allow an event queue to be updated during a signal
1580 was missing. For main.c, a cntrl-c simulation termination wasn't
1583 * The simulation would not correctly restart if an event requested
1584 that the simulation be halted.
1586 * psim.c (psim_options): Add hack to -i option to optionally
1587 include a level vis -i2.
1588 (psim_usage): Document.
1590 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1604 (event_queue_tick): Check that processing isn't still being
1607 * gen-idecode.c (print_run_until_stop_body): Call
1608 event_queue_process_events to clear possibly pending events before

1613 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1616 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1636 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1637 to be initialized independant of the rest of the simulation
1638 initalization. Otherwize a trace option explictly set from gdb
1639 could be overridden by hw_trace.
1641 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1643 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

1692 output expressions in idecode.h file.

1704 was too compilicated. The cache table did not allow values to be
1705 computed from cache entries. #defines could only be used when a
1706 cache was present, remove the restriction.
1708 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1709 scratch variable is defined when a cache entry is beinf
1710 filled. Change the definition of a COMPUTE variable to be defined
1711 when the cache entry is being used.
1712 * gen-icache.c: Update.
1714 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1730 * configure.in (enable-sim-icache): Clarify description. Make
1731 #define one of the defaults regardless of the cache. Probably
1732 should revamp and add a separate option.
