1060 after the specified POLL_QUIT_INTERVAL.
1062 1999-02-22 Jim Lemke <jlemke@cygnus.com>
1064 * dc-complex: Force expansion on all bits of field BO.
1065 Previously, the least-significant (prediction) bit was ignored.
1066 * ppc-instructions (conditional branches): Implement mpc860c0 option.
1067 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
1068 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
1069 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
1070 * interrupts.c (program_interrupt): Added handling for above interrupt.
1072 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1074 Make the simulator compatible with the MPC750. It would be nicer
1075 to make this a real multi-sim, but that's more work than we have
1077 * emul_generic.c (emul_add_tree_options): Only require strict
1078 alignment if it was explicitly requested at configuration time.
1079 Don't make it the default for little-endian machines.
1080 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1081 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1082 THRM2, THRM3): Plop in the MPC750 SPR registers.
1083 (DABR): This is weird. This was HID5, but the PPC spec says this
1084 should be DABR; why did some random processor use it for something
1085 else? The HID5 entry dates back to the original checkin of the
1086 simulator code in 1995, so remove it.
1087 * sim_calls.c (register_names): Delete this; since the user can
1088 now change GDB's list of register names dynamically, we can't
1089 pretend there's a static mapping here.
1090 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1091 function to get the register name. That ought to be accurate.
1092 However, we're changing a compile-time dependency (using the
1093 REGISTER_NAMES macro) into a link- and run-time dependency
1094 (calling REGISTER_NAME, which happens to be a function call on the
1097 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1099 * igen.c(gen_semantics_[ch]): setup/use of new option
1101 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
1102 ppc-instructions(the four branch insn groups): detect problematic br's.
1103 psim.c(is_num - added, psim_options): Parse and init new option.
1104 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

1123 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1124 fractional type, so that quiet NaN's aren't treated like
1127 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1129 * table.c (table_open): For cygwin hosts, we need to use the
1130 return value from the read routine as the number of bytes to
1131 process. This apparently is due to text-mode vs binary-mode. If
1132 the mounts are done text-mode, then the size returnedby fstat()
1133 may be different than the number of bytes "read" in text mode.
1135 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1137 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1158 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1160 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1161 but there was no such target, only plain psim. So I changed the
1162 run target to depend on psim.
1164 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1166 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1167 now defined in ../common/aclocal.m4, and the double definition causes

1570 determine the simulation speed by looking at the number of elapsed
1571 ticks recorded by the event queue.
1573 * psim.c (psim_write_register, psim_read_register): Force the cpu
1574 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1575 next cpu would be zero any way.
1577 * mon.c (mon_print_info): If possible, print the system cycle
1578 performance. This is an indication of the number of instructions
1581 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1583 * The code to allow an event queue to be updated during a signal
1584 was missing. For main.c, a cntrl-c simulation termination wasn't
1587 * The simulation would not correctly restart if an event requested
1588 that the simulation be halted.
1590 * psim.c (psim_options): Add hack to -i option to optionally
1591 include a level vis -i2.
1592 (psim_usage): Document.
1594 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

1611 * gen-idecode.c (print_run_until_stop_body): Call
1612 event_queue_process_events to clear possibly pending events before

1617 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1620 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1640 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1641 to be initialized independant of the rest of the simulation
1642 initalization. Otherwize a trace option explictly set from gdb
1643 could be overridden by hw_trace.
1645 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1647 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

1696 output expressions in idecode.h file.

1707 * The code that put values in and extracted values from the cache
1708 was too compilicated. The cache table did not allow values to be
1709 computed from cache entries. #defines could only be used when a
1710 cache was present, remove the restriction.
1712 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1713 scratch variable is defined when a cache entry is beinf
1714 filled. Change the definition of a COMPUTE variable to be defined
1715 when the cache entry is being used.
1716 * gen-icache.c: Update.
1718 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1731 * igen.c (main): Change 'R' option so that it does not force the
1734 * configure.in (enable-sim-icache): Clarify description. Make
1735 #define one of the defaults regardless of the cache. Probably
1736 should revamp and add a separate option.
