1058 1999-04-02 Keith Seitz <keiths@cygnus.com>
1060 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
1061 the frequency at which the poll_quit callback is called.
1062 (poll_quit_count): New global.
1063 (sim_io_poll_quit): Only call the poll_quit callback
1064 after the specified POLL_QUIT_INTERVAL.
1066 1999-02-22 Jim Lemke <jlemke@cygnus.com>
1068 * dc-complex: Force expansion on all bits of field BO.
1069 Previously, the least-significant (prediction) bit was ignored.
1070 * ppc-instructions (conditional branches): Implement mpc860c0 option.
1071 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
1072 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
1073 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
1074 * interrupts.c (program_interrupt): Added handling for above interrupt.
1076 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1078 Make the simulator compatible with the MPC750. It would be nicer
1079 to make this a real multi-sim, but that's more work than we have
1081 * emul_generic.c (emul_add_tree_options): Only require strict
1082 alignment if it was explicitly requested at configuration time.
1083 Don't make it the default for little-endian machines.
1084 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1085 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1086 THRM2, THRM3): Plop in the MPC750 SPR registers.
1087 (DABR): This is weird. This was HID5, but the PPC spec says this
1088 should be DABR; why did some random processor use it for something
1089 else? The HID5 entry dates back to the original checkin of the
1090 simulator code in 1995, so remove it.
1091 * sim_calls.c (register_names): Delete this; since the user can
1092 now change GDB's list of register names dynamically, we can't
1093 pretend there's a static mapping here.
1094 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1095 function to get the register name. That ought to be accurate.
1096 However, we're changing a compile-time dependency (using the
1097 REGISTER_NAMES macro) into a link- and run-time dependency
1098 (calling REGISTER_NAME, which happens to be a function call on the
1101 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1103 * igen.c(gen_semantics_[ch]): setup/use of new option
1105 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
1106 ppc-instructions(the four branch insn groups): detect problematic br's.
1107 psim.c(is_num - added, psim_options): Parse and init new option.
1108 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

1112 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

1123 poll the external environment.

1127 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1128 fractional type, so that quiet NaN's aren't treated like
1131 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1133 * table.c (table_open): For cygwin hosts, we need to use the
1134 return value from the read routine as the number of bytes to
1135 process. This apparently is due to text-mode vs binary-mode. If
1136 the mounts are done text-mode, then the size returnedby fstat()
1137 may be different than the number of bytes "read" in text mode.
1139 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1141 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1158 * configure: Regenerate.
1159 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1160 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1162 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1164 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1165 but there was no such target, only plain psim. So I changed the
1166 run target to depend on psim.
1168 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1170 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1171 now defined in ../common/aclocal.m4, and the double definition causes

1571 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1573 * When performance monitoring is disabled, it is still possible to
1574 determine the simulation speed by looking at the number of elapsed
1575 ticks recorded by the event queue.
1577 * psim.c (psim_write_register, psim_read_register): Force the cpu
1578 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1579 next cpu would be zero any way.
1581 * mon.c (mon_print_info): If possible, print the system cycle
1582 performance. This is an indication of the number of instructions
1585 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1587 * The code to allow an event queue to be updated during a signal
1588 was missing. For main.c, a cntrl-c simulation termination wasn't
1591 * The simulation would not correctly restart if an event requested
1592 that the simulation be halted.
1594 * psim.c (psim_options): Add hack to -i option to optionally
1595 include a level vis -i2.
1596 (psim_usage): Document.
1598 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1599 cntrl-c occures schedule an event to halt the simulation.
1600 (main): Catch CNTRL-C signals with the function cntrl_c.

1609 so that it is tolerant of halts.
1610 (event_queue_init): Start the event queue out with processing
1612 (event_queue_tick): Check that processing isn't still being
1615 * gen-idecode.c (print_run_until_stop_body): Call
1616 event_queue_process_events to clear possibly pending events before
1617 starting a simulation run. Re-arange main loop so that simulator
1618 is correctly restarted when an event halts the simulation.
1620 * psim.c (psim_halt): Handle an event halting the simulation.
1621 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1624 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1626 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

1632 here. Update to new format.

1644 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1645 to be initialized independant of the rest of the simulation
1646 initalization. Otherwize a trace option explictly set from gdb
1647 could be overridden by hw_trace.
1649 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1651 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1652 debug.c. It could be much simpler.

1693 * gen-icache.c (print_icache_extraction): For a cache entry of
1694 the form <name>_is_<const> where it is a boolean field, generate
1695 the result of the expression instead of the expression its self.

1700 output expressions in idecode.h file.
1702 * gen-icache.c (print_icache_body): Output them here.
1704 * ppc-opcode-complex: Clarify constant values for SPR==LR register

1711 * The code that put values in and extracted values from the cache
1712 was too compilicated. The cache table did not allow values to be
1713 computed from cache entries. #defines could only be used when a
1714 cache was present, remove the restriction.
1716 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1717 scratch variable is defined when a cache entry is beinf
1718 filled. Change the definition of a COMPUTE variable to be defined
1719 when the cache entry is being used.
1720 * gen-icache.c: Update.
1722 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1735 * igen.c (main): Change 'R' option so that it does not force the
1738 * configure.in (enable-sim-icache): Clarify description. Make
1739 #define one of the defaults regardless of the cache. Probably
1740 should revamp and add a separate option.

1755 device after it was deleted. Instead add and remove cap's from the
1756 cap db as they are created and deleted. This ensuring that a
1757 capibility is only used during the lifetime of the corresponding

3277 * configure.in: Adjust filter flag so that default includes 32bit
