1443
1444 1999-04-02  Keith Seitz  <keiths@cygnus.com>
1445
1446         * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
1447         the frequency at which the poll_quit callback is called.
1448         (poll_quit_count): New global.
1449         (sim_io_poll_quit): Only call the poll_quit callback
1450         after the specified POLL_QUIT_INTERVAL.
1451
1452 1999-02-22  Jim Lemke  <jlemke@cygnus.com>
1453
1454         * dc-complex: Force expansion on all bits of field BO.
1455         Previously, the least-significant (prediction) bit was ignored.
1456         * ppc-instructions (conditional branches): Implement mpc860c0 option.
1457         * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.

1461
1462 1999-02-01  Jim Blandy  <jimb@zwingli.cygnus.com>
1463
1464         Make the simulator compatible with the MPC750.  It would be nicer
1465         to make this a real multi-sim, but that's more work than we have
1466         time for.
1467         * emul_generic.c (emul_add_tree_options): Only require strict
1468         alignment if it was explicitly requested at configuration time.
1469         Don't make it the default for little-endian machines.
1470         * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1471         MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1472         THRM2, THRM3): Plop in the MPC750 SPR registers.
1473         (DABR): This is weird.  This was HID5, but the PPC spec says this
1474         should be DABR; why did some random processor use it for something
1475         else?  The HID5 entry dates back to the original checkin of the
1476         simulator code in 1995, so remove it.
1477         * sim_calls.c (register_names): Delete this; since the user can
1478         now change GDB's list of register names dynamically, we can't
1479         pretend there's a static mapping here.
1480         (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1481         function to get the register name.  That ought to be accurate.
1482         However, we're changing a compile-time dependency (using the
1483         REGISTER_NAMES macro) into a link- and run-time dependency
1484         (calling REGISTER_NAME, which happens to be a function call on the
1485         PPC).
1486
1487 1999-01-22  Jim Lemke <jlemke@cygnus.com>
1488
1489         * igen.c(gen_semantics_[ch]): setup/use of new option
1490         (-o mpc860c0[=n]).
1491         interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
1492         ppc-instructions(the four branch insn groups): detect problematic br's.
1493         psim.c(is_num - added, psim_options): Parse and init new option.
1494         These changes are currently under #ifdef WITH_OPTION_MPC860C0.
1495
1496 1998-12-01  Ken Raeburn  <raeburn@cygnus.com>
1497

1505         (sim_events_poll): Copy function from common/sim-events.c.
1506         (event_queue_init): Copy scheduling of sim_events_poll from same.
1507
1508         * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
1509         poll the external environment.
1510
1511 1998-11-19  Michael Meissner  <meissner@cygnus.com>
1512
1513         * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1514         fractional type, so that quiet NaN's aren't treated like
1515         Infinities.
1516
1517 Mon Sep 28 09:42:45 1998  Drew Moseley  <dmoseley@cygnus.com>
1518
1519         * table.c (table_open): For cygwin hosts, we need to use the
1520         return value from the read routine as the number of bytes to
1521         process.  This apparently is due to text-mode vs binary-mode.  If
1522         the mounts are done text-mode, then the size returnedby fstat()
1523         may be different than the number of bytes "read" in text mode.
1524

1549
1550         * Makefile.in: The run target depended on a target psim$(EXEEXT),
1551         but there was no such target, only plain psim.  So I changed the
1552         run target to depend on psim.

1555
1556         * aclocal.m4:  Remove defs of AM_EXEEXT and AM_CYGWIN32.  These are
1557         now defined in ../common/aclocal.m4, and the double definition causes
1558         problems with AC_SUBST of EXEEXT.
1559         * configure:  Regenerate.

1766 Fri Apr  4 17:54:36 1997  Jim Wilson  <wilson@cygnus.com>
1767
1768         * Makefile.in (tmp-hw, tmp-pk): Use for loop to eliminate duplicates
1769         rather than the non-portable cat -n.

1829
1830         * Many of the ppc-opcode-* files are identical baring the type of
1831         lookup table.  Instead of having multiple tables, igen can do this
1832         via an additional option.
1833
1834         * ld-decode.h, ld-decode.c (force_decode_gen_type): New function,
1835         allow the type of generated table specified in the decode file to
1836         be overridden.
1837
1838         * ld-decode.c (load_decode_table): Allow the table type to be
1839         overridden.
1840
1841         * igen.c (main): Add -T <mechanism> option so that an overriding
1842         instruction decode mechanism can be specified.
1843
1844         * configure.in: New option --sim-decode-mechanism to control
1845         igen's new -T <mechanism> flag.

1853         integer field.
1854         (even_queue_{init,schedule_after_signal,tick}): Conditionalize use
1855         of sigprocmask to appropriate autoconf test.
1856
1857         * main.c ({cntrl_c,main}): Use RETSIGTYPE for signal return type,

1861         * Makefile.in (callback.o): Define HAVE_CONFIG_H, so callback.c
1862         includes our config.h.
1863
1864 Tue Feb  4 13:42:59 1997  Doug Evans  <dje@canuck.cygnus.com>

1873
1874 Wed Feb  5 10:56:27 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1875
1876         * Property create/initialization still wasn't correctly ordered.
1877         Should be delaying everything related to ihandle creation until
1878         after the rest of the tree has been established.
1879
1880         * device.c (device_find_ihandle_runtime_property): Update.
1881         (device_add_ihandle_runtime_property): Update.
1882
1883         * tree.c (parse_ihandle_property): Delay lookup of the device to

1893
1894 Tue Feb  4 17:44:51 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1895
1896         * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1897         works for normal and boolean table entries.
1898
1899         * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1900         valid.  Handle this just like *_{read,write}_register now handles
1901         it.
1902
1903 Mon Feb  3 17:18:16 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1904
1905         * events.c (insert_event_entry): Correct loop termination
1906         assertions.

1909
1910         * psim.c (psim_options): Add new option -c for max-iterations or
1911         count.
1912         (psim_usage): Document.
1913         (psim_max_iterations_exceeded): New function, abort simulation if
1914         max iterations exceeded.
1915
1916         * gen-idecode.c: Re-work the table lookup code so that it assumes
1917         that the entry is a leaf by default.  Simplify the boolean table
1918         entry code so that it involves a mask + test instead of shift +
1919         shift + mask + test.
1920
1921         * gen-idecode.c: Correct generated igen body so that it no drops
1922         or doubles clock interrupts.
1923
1924
1925 Thu Jan 30 11:23:20 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1926
1927         * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to

1934
1935         * configure.in (sim_callback): If the gdb is post 4.16, configure
1936         callback support from the common directory.
1937         * configure: Regenerate.
1938
1939         * Makefile.in (BUILT_SRC_WO_CONFIG): Add targ-vals.{h,def} and

1941         (GDB_OBJ): Add callback support configured in.
1942         (gentmap,targ-vals.def): Build from common directory.
1943         (targ-vals.h,targ-map.c): Build by running gentmap.
1944         (callback.o): Build from source in common directory.
1945         (targ-map.o): Add dependency.
1946         (clean): Remove gentmap.
1947
1948 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1949
1950         * igen wasn't aborting if the opcode table contained no valid
1951         fields.
1952
1953         * misc.c (name2i): Possibly abort if an invalid name is
1954         encountered.
1955         * ld-decode.c: Abort if the table type isn't found.
1956
1957 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1958
1959         * When performance monitoring is disabled, it is still possible to
1960         determine the simulation speed by looking at the number of elapsed
1961         ticks recorded by the event queue.
1962
1963         * psim.c (psim_write_register, psim_read_register): Force the cpu
1964         to zero when it is either of `-1' or `nr_cpus'.  In both cases the
1965         next cpu would be zero any way.
1966
1967         * mon.c (mon_print_info): If possible, print the system cycle
1968         performance.  This is an indication of the number of instructions
1969         per second.
1970
1971 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
1972
1973         * The code to allow an event queue to be updated during a signal
1974         was missing.  For main.c, a cntrl-c simulation termination wasn't
1975         handled cleanly.
1976
1977         * The simulation would not correctly restart if an event requested
1978         that the simulation be halted.
1979
1980         * psim.c (psim_options): Add hack to -i option to optionally
1981         include a level vis -i2.
1982         (psim_usage): Document.
1983
1984         * main.c (cntrl_c, cntrl_c_simulation): New functions.  When a
1985         cntrl-c occures schedule an event to halt the simulation.
1986         (main): Catch CNTRL-C signals with the function cntrl_c.
1987
1988         * events.c (event_queue_process): Mask interrupts while
1989         manipulating the async event queue.
1990         (event_queue_init): Ditto.
1991         (event_queue_schedule_after_signal): Ditto.
1992
1993         * events.c (event_queue_process): Mark the event queue as being in
1994         the processing state when processing has started.  Adjust code
1995         so that it is tolerant of halts.
1996         (event_queue_init): Start the event queue out with processing
1997         false.
1998         (event_queue_tick): Check that processing isn't still being
1999         performed.
2000
2001         * gen-idecode.c (print_run_until_stop_body): Call
2002         event_queue_process_events to clear possibly pending events before
2003         starting a simulation run.  Re-arange main loop so that simulator
2004         is correctly restarted when an event halts the simulation.
2005
2006         * psim.c (psim_halt): Handle an event halting the simulation.
2007         * psim.c (psim_init): Adjust initial cpu - == -1 - to match
2008         reworked idecode.
2009
2010 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
2011
2012         * ppc-opcode-complex: Correct typo - was expanding ORA instead of
2013         RA.  Based on instruction frequency stats, expand additional
2014         instructions.
2015         * ppc-instructions: Change all `RA == 0' to RA_is_0.
2016
2017         * ppc-opcode-stupid: Move all but the basic table in -complex into
2018         here.  Update to new format.
2019
2020         * Makefile.in (tmp-defines): New target. Force defines.h to always
2021         be built.  Hence get ppc-opcode-goto to build.
2022
2023 Tue Jan 28 13:00:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
2024
2025         * hw_com.c (hw_com_instance_read, hw_com_instance_write):
2026         Implement.
2027
2028 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
2029
2030         * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
2031         to be initialized independant of the rest of the simulation
2032         initalization.  Otherwize a trace option explictly set from gdb
2033         could be overridden by hw_trace.
2034
2035         * psim.c (psim_options): Clarify reason why the trace ioctl occures.
2036
2037         * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
2038         debug.c.  It could be much simpler.
2039
2040 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
2041
2042         * Some devices support removable media.  Add hooks to the disk
2043         device so that it supports this.
2044
2045         * device.c (device_add_string_array_property,
2046         device_find_string_array_property): New functions, manipulate
2047         properties containing an array of strings.
2048         (device_find_string_property): Allow a string array.
2049         (device_init_static_properties): Update.
2050         (device_init_runtime_properties): Update.
2051
2052         * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
2053         media.  If no file image is specified, use the next one in the
2054         image property list.
2055         (hw_disk_init_address): Change the file property so that it is a
2056         string array - use the first entry for the initial file image.
2057
2058         * tree.c (print_string_aray_property): New function - print a
2059         string array.
2060         (print_properties): Adjust.
2061         (print_string): Write a string, handling double quotes.
2062
2063         * device.h: Define an ioctl to `change-media' with an optional new
2064         media image.
2065
2066         * hw_disk.c: Allow floppy disk devices to be specified.
2067
2068         * psim.c (psim_command): New function, parse more complex psim
2069         commands such as "change-media" and "trace".
2070         * sim_calls.c (sim_do_command): Use.
2071
2072 Wed Jan 22 09:38:33 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
2073
2074         * For expressions like (RA == 0) that are entered in to the cache
2075         as RA_is_0. If possible generate the result of the expression so
2076         that the compiler gets a better chance of eliminating dead
2077         branches.
2078
2079         * gen-icache.c (print_icache_extraction): For a cache entry of
2080         the form <name>_is_<const> where it is a boolean field, generate
2081         the result of the expression instead of the expression its self.
2082         (print_icache_body): Remove code that was looking for *_is_0 and
2083         then generating corresponding definitions.
2084
2085         * gen-icache.c (print_icache_struct): If there is no cache, do not
2086         output expressions in idecode.h file.
2087
2088         * gen-icache.c (print_icache_body): Output them here.
2089
2090         * ppc-opcode-complex: Clarify constant values for SPR==LR register
2091         expansion.
2092
2093         * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
2094
2095 Wed Jan 22 12:24:52 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
2096
2097         * The code that put values in and extracted values from the cache
2098         was too compilicated.  The cache table did not allow values to be
2099         computed from cache entries.  #defines could only be used when a
2100         cache was present, remove the restriction.
2101
2102         * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
2103         scratch variable is defined when a cache entry is beinf
2104         filled. Change the definition of a COMPUTE variable to be defined
2105         when the cache entry is being used.
2106         * gen-icache.c: Update.
2107

3498
3499         * configure.in (icache): Extend icache flag to include an insn
3500         option.  If specifyed the insn - aka instruction - is included in

3516 Mon Jul 22 20:00:25 1996  Andrew Cagney  <cagney@highland.com.au>
3517
3518         * emul_generic.c (emul_add_tree_options): Was incorrectly setting
3519         the strict-alignment option when hardwired for non-strict
3520         alignment.
3521
3522 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

3527         not my_index.
3528
3529 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
3530
3531         * gen-idecode.c: Output the complete run_until_stop function
3532         instead of just the code to handle a single instruction issue.
3533         * : Have the generated idecode.c include inline.c (instead of psim.c).
3534
3535         * std-config.h: Change psim.c so that it isn't inlined (as this is
3536         no longer needed).
3537
3538         * psim.c (run_until_stop): Delete the old run_until_stop function
3539         instead calling the idecode_run and idecode_run_until_stop
3540         functions that gen-idecode.c is now creating.
3541
3542 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
3543

3550
3551         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
3552         eliminate trace statements.
3553
3554         * debug.c: Change trace format so that it is consistent

3561         current instructions name and source line number.
3562
3563         * gen-semantics.c, gen-icache.c: Adjust generated ITRACE calls to

3567         corresponding call to ITRACE so that it still matches.
3568
3569         * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
3570         of ITRACE.  The CPP line directives would have previously set the

3573 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
3574
3575         * gen-idecode.c (print_jump_until_stop_body): New function and
3576         idecode generation option.  Instead of generating and calling
3577         separate functions containing the semantic and icache code
3578         generate a single monolythic function and use goto's (and GCC's
3579         indirect jump) to move between code blocks.

3582
3583         * configure.in: New option --enable-sim-jump (default disabled)
3584
3585         * ppc-instructions: Eliminate any uses of labels and goto's.
3586         These result in duplicate declarations when a single flat function
3587         is being create.
3588
3589         * ppc-opcode-jump: New file.  Set of opcode rules useful when

3597         * igen.c: Add option (-C) to generate semantics in the instruction
3598         decode functions.
3599
3600         * configure.in (--enable-sim-icache): Accept an option list such
3601         as 1024,define.  Add a new choice to the list - semantic - which
3602         will cause igen to generate instruction decode functions that
3603         include the corresponding semantic code.
3604
3605 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
3606
3607         * configure.in: New option --enable-sim-line-nr (default enabled).
3608         Enable/disable the inclusion of CPP line directives in the
3609         generated files.  Such directives refer back to the source files
3610         used when generating the simulator code.
3611
3612         * Makefile.in (sim_line_nr): Pass to igen.
3613
3614 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

3616         * igen.c (main): Revamp the options so that more letters are
3617         available.
3618
3619         * configure.in: Adjust to match igen's revamped options

3621 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
3622
3623         * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
3624         that they use the same technique as igen (ie a dummy targets
3625         tmp-pk and tmp-hw are created).

3661         * igen.c: Remove the opcode filter table loading code.
3662         * Makefile.in (filter.o): Adjust
3663         * configure.in: Adjust filter flag so that default includes 32bit

4545
4546         * corefile-n.h (core_map_read_N): When mapping from an address to
4547         a device, do not subtract the devices base.  The device its self
4548         can do this.  Brings the behavour into line with OpenBoot.

4558
4559         * device.c (attach_device_interrupt_edge): New. Interrupt model
4560         did not allow interrupts to be wired up as a general net (edges).
4561         Re-implement so that interrupt events can be passed to multiple
4562         controllers and interrupt controllers can further propogate
4563         interrupt events.
4564

4586
4587         * device.c (external_to_device) : New function that provides a
4588         standard mapping between a devices internal representation (a
4589         pointer) and its external (or what is passed to a client)
4590         representation (a phandle).  Implement using the cap object
4591         attached to the root node.
4592
4593         * device.c (device_to_external) : Ditto
4594         * device.c (external_to_device_instance) : Ditto but for ihandle
4595         and device instance.
4596         * device.c (device_instance_to_external) : Ditto
4597
4598         * Makefile (device.o): Add dependency on cap.
4599
4600         * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
4601         needing to translate between internal and external representations
4602         changed to use the external_to_device et.al. device operations.
4603         * emul_chirp.c (chirp_emul_*) : Ditto
4604
4605         * Makefile (emul_chirp.o): Remove dependency on cap

4613
4614         * emul_generic.c (emul_write_buffer): Use vm faulting byte
4615         read/write calls for buffer transfers.  This will cause a fault to
4616         occure if the transfer fails.  CHRP catches the fault while the
4617         others suffer the consequences.
4618         (emul_read_buffer): Ditto.
4619         (emul_write_word): Ditto.

4627         return from a client service call.
4628
4629         * emul_chirp.c (services): Add all OpenBoot services to table.
