1383 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
1385 * sim-endian.h: Don't have parameters on macro definitions which
1386 are simply renaming functions, to permit use of XCONCAT2 in both
1387 the macro name and the arguments in a use of such a definition.
1389 2000-11-15 Jim Blandy <jimb@redhat.com>
1391 * sim_calls.c: Doc fix.
1392 (sim_fetch_register, sim_store_register): Call
1393 gdbarch_register_name directly, instead of going through
1394 REGISTER_NAME macro.
1396 2000-10-24 Geoff Keating <geoffk@cygnus.com>
1398 * ppc-instructions (lfsux): Correct XO field of lfsux instruction.

1423 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
1425 * configure: Regenerated to track ../common/aclocal.m4 changes.
1427 1999-05-08 Felix Lee <flee@cygnus.com>
1429 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1430 * configure: Regenerated to track ../common/aclocal.m4 changes.
1432 1999-04-02 Keith Seitz <keiths@cygnus.com>
1434 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
1435 the frequency at which the poll_quit callback is called.

1438 after the specified POLL_QUIT_INTERVAL.
1440 1999-02-22 Jim Lemke <jlemke@cygnus.com>
1442 * dc-complex: Force expansion on all bits of field BO.
1443 Previously, the least-significant (prediction) bit was ignored.
1444 * ppc-instructions (conditional branches): Implement mpc860c0 option.
1445 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
1446 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

1448 * interrupts.c (program_interrupt): Added handling for above interrupt.
1450 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1452 Make the simulator compatible with the MPC750. It would be nicer
1453 to make this a real multi-sim, but that's more work than we have
1455 * emul_generic.c (emul_add_tree_options): Only require strict
1456 alignment if it was explicitly requested at configuration time.
1457 Don't make it the default for little-endian machines.
1458 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1459 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1460 THRM2, THRM3): Plop in the MPC750 SPR registers.
1461 (DABR): This is weird. This was HID5, but the PPC spec says this
1462 should be DABR; why did some random processor use it for something
1463 else? The HID5 entry dates back to the original checkin of the
1464 simulator code in 1995, so remove it.
1465 * sim_calls.c (register_names): Delete this; since the user can
1466 now change GDB's list of register names dynamically, we can't
1467 pretend there's a static mapping here.
1468 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1469 function to get the register name. That ought to be accurate.
1470 However, we're changing a compile-time dependency (using the
1471 REGISTER_NAMES macro) into a link- and run-time dependency
1472 (calling REGISTER_NAME, which happens to be a function call on the
1475 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1477 * igen.c(gen_semantics_[ch]): setup/use of new option
1479 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
1480 ppc-instructions(the four branch insn groups): detect problematic br's.
1481 psim.c(is_num - added, psim_options): Parse and init new option.
1482 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
1484 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
1486 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

1497 poll the external environment.
1499 1998-11-19 Michael Meissner <meissner@cygnus.com>
1501 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1502 fractional type, so that quiet NaN's aren't treated like
1505 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1507 * table.c (table_open): For cygwin hosts, we need to use the
1508 return value from the read routine as the number of bytes to
1509 process. This apparently is due to text-mode vs binary-mode. If
1510 the mounts are done text-mode, then the size returnedby fstat()
1511 may be different than the number of bytes "read" in text mode.
1513 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1515 * emul_netbsd.c (do_open): fix order-of-evaluation problem.
1520 1998-09-03 Michael Meissner <meissner@cygnus.com>
1522 * emul_{netbsd,unix}.c: Update copyright year.

1526 * sim_calls.c (sim_fetch_register, sim_store_register):
1527 return zero when nothing to do.
1529 1998-06-26 Michael Meissner <meissner@cygnus.com>
1531 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1532 * configure: Regenerate.
1533 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1534 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1536 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1538 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1539 but there was no such target, only plain psim. So I changed the
1540 run target to depend on psim.
1542 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1544 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are

1951 * psim.c (psim_write_register, psim_read_register): Force the cpu
1952 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1953 next cpu would be zero any way.
1955 * mon.c (mon_print_info): If possible, print the system cycle
1956 performance. This is an indication of the number of instructions
1959 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1961 * The code to allow an event queue to be updated during a signal

1966 that the simulation be halted.
1968 * psim.c (psim_options): Add hack to -i option to optionally
1969 include a level vis -i2.
1970 (psim_usage): Document.

2018 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
2019 to be initialized independant of the rest of the simulation
2020 initalization. Otherwize a trace option explictly set from gdb
2021 could be overridden by hw_trace.
2023 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
2025 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
2026 debug.c. It could be much simpler.
2028 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

2044 string array - use the first entry for the initial file image.

2068 the form <name>_is_<const> where it is a boolean field, generate
2069 the result of the expression instead of the expression its self.
2070 (print_icache_body): Remove code that was looking for *_is_0 and
2071 then generating corresponding definitions.

3650 * Makefile.in (filter.o): Adjust
3651 * configure.in: Adjust filter flag so that default includes 32bit
