1370 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
1372 * sim-endian.h: Don't have parameters on macro definitions which
1373 are simply renaming functions, to permit use of XCONCAT2 in both
1374 the macro name and the arguments in a use of such a definition.
1376 2000-11-15 Jim Blandy <jimb@redhat.com>
1378 * sim_calls.c: Doc fix.
1379 (sim_fetch_register, sim_store_register): Call
1380 gdbarch_register_name directly, instead of going through
1381 REGISTER_NAME macro.
1383 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1385 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1414 1999-05-08 Felix Lee <flee@cygnus.com>
1416 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1417 * configure: Regenerated to track ../common/aclocal.m4 changes.
1419 1999-04-02 Keith Seitz <keiths@cygnus.com>
1421 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak

1437 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1439 Make the simulator compatible with the MPC750. It would be nicer
1440 to make this a real multi-sim, but that's more work than we have
1442 * emul_generic.c (emul_add_tree_options): Only require strict
1443 alignment if it was explicitly requested at configuration time.
1444 Don't make it the default for little-endian machines.
1445 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1446 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1447 THRM2, THRM3): Plop in the MPC750 SPR registers.
1448 (DABR): This is weird. This was HID5, but the PPC spec says this
1449 should be DABR; why did some random processor use it for something
1450 else? The HID5 entry dates back to the original checkin of the
1451 simulator code in 1995, so remove it.
1452 * sim_calls.c (register_names): Delete this; since the user can
1453 now change GDB's list of register names dynamically, we can't
1454 pretend there's a static mapping here.
1455 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1456 function to get the register name. That ought to be accurate.
1457 However, we're changing a compile-time dependency (using the
1458 REGISTER_NAMES macro) into a link- and run-time dependency
1459 (calling REGISTER_NAME, which happens to be a function call on the
1462 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1464 * igen.c(gen_semantics_[ch]): setup/use of new option
1466 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.

1468 psim.c(is_num - added, psim_options): Parse and init new option.
1469 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
1471 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
1473 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

1484 poll the external environment.
1486 1998-11-19 Michael Meissner <meissner@cygnus.com>
1488 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1489 fractional type, so that quiet NaN's aren't treated like
1492 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1494 * table.c (table_open): For cygwin hosts, we need to use the
1495 return value from the read routine as the number of bytes to
1496 process. This apparently is due to text-mode vs binary-mode. If
1497 the mounts are done text-mode, then the size returnedby fstat()
1498 may be different than the number of bytes "read" in text mode.
1500 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1502 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1514 return zero when nothing to do.
1516 1998-06-26 Michael Meissner <meissner@cygnus.com>
1518 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1519 * configure: Regenerate.
1520 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1521 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1523 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1525 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1526 but there was no such target, only plain psim. So I changed the
1527 run target to depend on psim.
1529 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1531 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1532 now defined in ../common/aclocal.m4, and the double definition causes
1533 problems with AC_SUBST of EXEEXT.
1534 * configure: Regenerate.
1536 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>
1538 * aclocal.m4: new file for AM_EXEEXT macro
1539 * configure.in: call AM_EXEEXT

1935 determine the simulation speed by looking at the number of elapsed
1936 ticks recorded by the event queue.
1938 * psim.c (psim_write_register, psim_read_register): Force the cpu
1939 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1940 next cpu would be zero any way.
1942 * mon.c (mon_print_info): If possible, print the system cycle
1943 performance. This is an indication of the number of instructions
1946 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1948 * The code to allow an event queue to be updated during a signal

1953 that the simulation be halted.
1955 * psim.c (psim_options): Add hack to -i option to optionally
1956 include a level vis -i2.
1957 (psim_usage): Document.

1976 * gen-idecode.c (print_run_until_stop_body): Call
1977 event_queue_process_events to clear possibly pending events before
1978 starting a simulation run. Re-arange main loop so that simulator
1979 is correctly restarted when an event halts the simulation.
1981 * psim.c (psim_halt): Handle an event halting the simulation.
1982 * psim.c (psim_init): Adjust initial cpu - == -1 - to match

2005 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
2006 to be initialized independant of the rest of the simulation
2007 initalization. Otherwize a trace option explictly set from gdb
2008 could be overridden by hw_trace.
2010 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
2012 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
2013 debug.c. It could be much simpler.
2015 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

2028 media. If no file image is specified, use the next one in the
2029 image property list.
2030 (hw_disk_init_address): Change the file property so that it is a
2031 string array - use the first entry for the initial file image.
2033 * tree.c (print_string_aray_property): New function - print a

2050 as RA_is_0. If possible generate the result of the expression so
2051 that the compiler gets a better chance of eliminating dead
2054 * gen-icache.c (print_icache_extraction): For a cache entry of
2055 the form <name>_is_<const> where it is a boolean field, generate
2056 the result of the expression instead of the expression its self.
2057 (print_icache_body): Remove code that was looking for *_is_0 and
2058 then generating corresponding definitions.
2060 * gen-icache.c (print_icache_struct): If there is no cache, do not
2061 output expressions in idecode.h file.
2063 * gen-icache.c (print_icache_body): Output them here.
2065 * ppc-opcode-complex: Clarify constant values for SPR==LR register
2068 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
2070 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
2072 * The code that put values in and extracted values from the cache
2073 was too compilicated. The cache table did not allow values to be
2074 computed from cache entries. #defines could only be used when a
2075 cache was present, remove the restriction.
