1362 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
1364 * sim-endian.h: Don't have parameters on macro definitions which
1365 are simply renaming functions, to permit use of XCONCAT2 in both
1366 the macro name and the arguments in a use of such a definition.
1368 2000-11-15 Jim Blandy <jimb@redhat.com>
1370 * sim_calls.c: Doc fix.
1371 (sim_fetch_register, sim_store_register): Call
1372 gdbarch_register_name directly, instead of going through
1373 REGISTER_NAME macro.
1375 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1377 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1406 1999-05-08 Felix Lee <flee@cygnus.com>
1408 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1409 * configure: Regenerated to track ../common/aclocal.m4 changes.
1411 1999-04-02 Keith Seitz <keiths@cygnus.com>
1413 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak

1429 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1431 Make the simulator compatible with the MPC750. It would be nicer
1432 to make this a real multi-sim, but that's more work than we have
1434 * emul_generic.c (emul_add_tree_options): Only require strict
1435 alignment if it was explicitly requested at configuration time.
1436 Don't make it the default for little-endian machines.
1437 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1438 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1439 THRM2, THRM3): Plop in the MPC750 SPR registers.
1440 (DABR): This is weird. This was HID5, but the PPC spec says this
1441 should be DABR; why did some random processor use it for something
1442 else? The HID5 entry dates back to the original checkin of the
1443 simulator code in 1995, so remove it.
1444 * sim_calls.c (register_names): Delete this; since the user can
1445 now change GDB's list of register names dynamically, we can't
1446 pretend there's a static mapping here.
1447 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1448 function to get the register name. That ought to be accurate.
1449 However, we're changing a compile-time dependency (using the
1450 REGISTER_NAMES macro) into a link- and run-time dependency
1451 (calling REGISTER_NAME, which happens to be a function call on the
1454 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1456 * igen.c(gen_semantics_[ch]): setup/use of new option
1458 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.

1460 psim.c(is_num - added, psim_options): Parse and init new option.
1461 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
1463 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
1465 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

1476 poll the external environment.
1478 1998-11-19 Michael Meissner <meissner@cygnus.com>
1480 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1481 fractional type, so that quiet NaN's aren't treated like
1484 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1486 * table.c (table_open): For cygwin hosts, we need to use the
1487 return value from the read routine as the number of bytes to
1488 process. This apparently is due to text-mode vs binary-mode. If
1489 the mounts are done text-mode, then the size returnedby fstat()
1490 may be different than the number of bytes "read" in text mode.
1492 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1494 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1506 return zero when nothing to do.
1508 1998-06-26 Michael Meissner <meissner@cygnus.com>
1510 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1511 * configure: Regenerate.
1512 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1513 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1515 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1517 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1518 but there was no such target, only plain psim. So I changed the
1519 run target to depend on psim.
1521 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1523 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1524 now defined in ../common/aclocal.m4, and the double definition causes
1525 problems with AC_SUBST of EXEEXT.
1526 * configure: Regenerate.
1528 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>
1530 * aclocal.m4: new file for AM_EXEEXT macro

1927 determine the simulation speed by looking at the number of elapsed
1928 ticks recorded by the event queue.
1930 * psim.c (psim_write_register, psim_read_register): Force the cpu
1931 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1932 next cpu would be zero any way.
1934 * mon.c (mon_print_info): If possible, print the system cycle
1935 performance. This is an indication of the number of instructions
1938 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1940 * The code to allow an event queue to be updated during a signal
1941 was missing. For main.c, a cntrl-c simulation termination wasn't
1944 * The simulation would not correctly restart if an event requested
1945 that the simulation be halted.
1947 * psim.c (psim_options): Add hack to -i option to optionally
1948 include a level vis -i2.
1949 (psim_usage): Document.

1968 * gen-idecode.c (print_run_until_stop_body): Call
1969 event_queue_process_events to clear possibly pending events before
1970 starting a simulation run. Re-arange main loop so that simulator
1971 is correctly restarted when an event halts the simulation.
1973 * psim.c (psim_halt): Handle an event halting the simulation.
1974 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1977 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1997 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1998 to be initialized independant of the rest of the simulation
1999 initalization. Otherwize a trace option explictly set from gdb
2000 could be overridden by hw_trace.
2002 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
2004 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
2005 debug.c. It could be much simpler.
2007 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
2009 * Some devices support removable media. Add hooks to the disk

2020 media. If no file image is specified, use the next one in the
2021 image property list.
2022 (hw_disk_init_address): Change the file property so that it is a
2023 string array - use the first entry for the initial file image.
2025 * tree.c (print_string_aray_property): New function - print a
2027 (print_properties): Adjust.

2042 as RA_is_0. If possible generate the result of the expression so
2043 that the compiler gets a better chance of eliminating dead
2046 * gen-icache.c (print_icache_extraction): For a cache entry of
2047 the form <name>_is_<const> where it is a boolean field, generate
2048 the result of the expression instead of the expression its self.
2049 (print_icache_body): Remove code that was looking for *_is_0 and
2050 then generating corresponding definitions.
2052 * gen-icache.c (print_icache_struct): If there is no cache, do not
2053 output expressions in idecode.h file.
2055 * gen-icache.c (print_icache_body): Output them here.
2057 * ppc-opcode-complex: Clarify constant values for SPR==LR register
2060 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
2062 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
2064 * The code that put values in and extracted values from the cache
2065 was too compilicated. The cache table did not allow values to be
2066 computed from cache entries. #defines could only be used when a
2067 cache was present, remove the restriction.
2069 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
2070 scratch variable is defined when a cache entry is beinf
2071 filled. Change the definition of a COMPUTE variable to be defined
2072 when the cache entry is being used.
2073 * gen-icache.c: Update.
