 372         * psim.c (psim_write_register, psim_read_register): Force the cpu
 373         to zero when it is either of `-1' or `nr_cpus'.  In both cases the
 374         next cpu would be zero any way.
 375
 376         * mon.c (mon_print_info): If possible, print the system cycle
 377         performance.  This is an indication of the number of instructions

 379
 380 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 381
 382         * The code to allow an event queue to be updated during a signal
 383         was missing.  For main.c, a cntrl-c simulation termination wasn't
 384         handled cleanly.
 385
 386         * The simulation would not correctly restart if an event requested
 387         that the simulation be halted.
 388
 389         * psim.c (psim_options): Add hack to -i option to optionally
 390         include a level vis -i2.
 391         (psim_usage): Document.
 392
 393         * main.c (cntrl_c, cntrl_c_simulation): New functions.  When a
 394         cntrl-c occures schedule an event to halt the simulation.
 395         (main): Catch CNTRL-C signals with the function cntrl_c.
 396
 397         * events.c (event_queue_process): Mask interrupts while
 398         manipulating the async event queue.
 399         (event_queue_init): Ditto.
 400         (event_queue_schedule_after_signal): Ditto.
 401
 402         * events.c (event_queue_process): Mark the event queue as being in
 403         the processing state when processing has started.  Adjust code
 404         so that it is tolerant of halts.
 405         (event_queue_init): Start the event queue out with processing
 406         false.
 407         (event_queue_tick): Check that processing isn't still being
 408         performed.
 409
 410         * gen-idecode.c (print_run_until_stop_body): Call
 411         event_queue_process_events to clear possibly pending events before
 412         starting a simulation run.  Re-arange main loop so that simulator
 413         is correctly restarted when an event halts the simulation.
 414
 415         * psim.c (psim_halt): Handle an event halting the simulation.
 416         * psim.c (psim_init): Adjust initial cpu - == -1 - to match
 417         reworked idecode.
 418
 419 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 420
 421         * ppc-opcode-complex: Correct typo - was expanding ORA instead of
 422         RA.  Based on instruction frequency stats, expand additional
 423         instructions.
 424         * ppc-instructions: Change all `RA == 0' to RA_is_0.
 425
 426         * ppc-opcode-stupid: Move all but the basic table in -complex into
 427         here.  Update to new format.
 428
 429         * Makefile.in (tmp-defines): New target. Force defines.h to always
 430         be built.  Hence get ppc-opcode-goto to build.
 431
 432 Tue Jan 28 13:00:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>

 438
 439         * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
 440         to be initialized independant of the rest of the simulation
 441         initalization.  Otherwize a trace option explictly set from gdb
 442         could be overridden by hw_trace.
 443
 444         * psim.c (psim_options): Clarify reason why the trace ioctl occures.
 445
 446         * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
 447         debug.c.  It could be much simpler.
 448
 449 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 450
 451         * Some devices support removable media.  Add hooks to the disk
 452         device so that it supports this.
 453
 454         * device.c (device_add_string_array_property,
 455         device_find_string_array_property): New functions, manipulate
 456         properties containing an array of strings.

 460
 461         * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
 462         media.  If no file image is specified, use the next one in the
 463         image property list.
 464         (hw_disk_init_address): Change the file property so that it is a
 465         string array - use the first entry for the initial file image.
 466
 467         * tree.c (print_string_aray_property): New function - print a
 468         string array.
 469         (print_properties): Adjust.
 470         (print_string): Write a string, handling double quotes.
 471
 472         * device.h: Define an ioctl to `change-media' with an optional new
 473         media image.
 474
 475         * hw_disk.c: Allow floppy disk devices to be specified.
 476
 477         * psim.c (psim_command): New function, parse more complex psim
 478         commands such as "change-media" and "trace".
 479         * sim_calls.c (sim_do_command): Use.
 480
 481 Wed Jan 22 09:38:33 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 482
 483         * For expressions like (RA == 0) that are entered in to the cache
 484         as RA_is_0. If possible generate the result of the expression so
 485         that the compiler gets a better chance of eliminating dead
 486         branches.
 487
 488         * gen-icache.c (print_icache_extraction): For a cache entry of
 489         the form <name>_is_<const> where it is a boolean field, generate
 490         the result of the expression instead of the expression its self.
 491         (print_icache_body): Remove code that was looking for *_is_0 and
 492         then generating corresponding definitions.
 493
 494         * gen-icache.c (print_icache_struct): If there is no cache, do not
 495         output expressions in idecode.h file.

 502         * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
 503
 504 Wed Jan 22 12:24:52 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 505
 506         * The code that put values in and extracted values from the cache
 507         was too compilicated.  The cache table did not allow values to be
 508         computed from cache entries.  #defines could only be used when a
 509         cache was present, remove the restriction.
 510
 511         * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
 512         scratch variable is defined when a cache entry is beinf
 513         filled. Change the definition of a COMPUTE variable to be defined
 514         when the cache entry is being used.
 515         * gen-icache.c: Update.
 516
 517         * ld-cache.h, ld-cache.c: Change field names so that their meaning

 520
 521         * gen-icache.h, gen-icache.c (print_icache_body): Make the three
 522         different types of cache code - put into cache, extract from
 523         cache, no cache - an explicit argument to print_icache_body.
 524         * gen-icache.c (print_icache_extraction): Ditto.
 525
 526         * gen-semantics.c (print_c_semantic): Update use.
 527         * gen-idecode.c (print_jump_insn): Update use.
 528         * gen-icache.c (print_icache_function): Update use.
 529
 530         * igen.c (main): Change 'R' option so that it does not force the
 531         cache.
 532
 533         * configure.in (enable-sim-icache): Clarify description.  Make
 534         #define one of the defaults regardless of the cache.  Probably
 535         should revamp and add a separate option.
 536
 537 Tue Jan 21 13:26:10 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 538
 539         * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
 540         partition numbering.

 544         (pk_disklabel_create_instance): Start expanding so that active
 545         partition selection is supported.
 546
 547 Mon Jan 20 11:20:15 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 548
 549         * The cap object was retaining a reference to the instance of a
 550         device after it was deleted. Instead add and remove cap's from the
 551         cap db as they are created and deleted.  This ensuring that a
 552         capibility is only used during the lifetime of the corresponding
 553         object.
 554
 555         * cap.h, cap.c: Correct cap type - was signed32 should be
 556         signed_cell.
 557
 558         * cap.c (cap_add, cap_remove): New methods for cap object that
 559         allow the explicit addition and removal of internal objects that
 560         the cap knows about.
 561
 562         * cap.c (cap_init): Rewrite.  Verify that the only objects
 563         remaining in the cap data base are those that were entered first.
 564         Thse objects will be the permenant ones.

 566         database.
 567
 568         * device.c (device_create_instance_from): Explicitly add device
 569         instances to the cap database.  Simplify create code.
 570         (device_instance_delete): Explicitly remove device instances from
 571         the cap database.
 572
 573         * device.c (device_create_from): Explicitly add a device to the

 589         size as arguments.  These may be multi cell values. Initially fix
 590         the memory code so that they check/detect this.  Leave the
 591         adjustment of any clients to later.
 592
 593         * hw_memory.c (hw_memory_instance_claim,
 594         hw_memory_instance_release): Handle multi-cell memory devices.

 619
 620         * hw_init.c (update_for_binary_section): Fix failure to allocate
 621         memory used by the binary in real-mode executions. If "claim"

 624
 625         * emul_chirp.c (emul_chirp_create): Specify that memory should be

1813
1814         * std-config.h (SEMANTICS_INLINE): By default, mask out the
1815         inlining of semantic functions from DEFAULT_INLINE.  Almost all
1816         configurations call the semantic code via a pointer so there is

1818
1819         * std-config.h (ICACHE_INLINE): Ditto.
1820

1848
1849         * gen-idecode.c (print_idecode_switch_illegal): Include a break
1850         when generating illegal instructions.  This was commented out
1851         which is a hangover from looking a at switch statements generated
1852         using indirect jumps.
1853
1854 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1855
1856         * igen.c (print_my_defines): Replaces print_define_my_index.
1857         Print both a definition for MY_INDEX and MY_PREFIX.
1858         * gen-icache.c (print_icache_function): Adjust.
1859         * gen-idecode.c (print_jump_insn): Adjust.

1861
1862         * gen-support.c (gen_support_h): Add optional include to created
1863         support.h so that, like cpu, it is optionally inlined for all

1866         same as cpu.[hc].
1867
1868         * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
1869         name for a lable and then branch to it.
1870
1871         * ppc-instructions (convert_to_integer, Floating Round to
1872         Single-Precision, Floating Convert from Integer Doubleword): Use
1873         LABEL and GOTO instead of the recently added switch statements.
1874
1875 Wed Jul 24 14:02:42 1996  Andrew Cagney  <cagney@sawnoff.highland.com.au>
1876
1877         * gen-idecode.c (print_run_until_stop_body): Too many rparen in
1878         generated code.
1879
1880 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

1885
1886         * configure: rebuild.
1887
1888 Mon Jul 22 23:25:08 1996  Andrew Cagney  <cagney@highland.com.au>
1889
1890         * configure.in (--enable-sim-hardware, --enable-sim-packages): New
1891         configuration options.  Let the user specify the packages or
1892         hardware devices that are to be included in the build.  Makes it
1893         possible for user packages to be specified.
1894
1895         * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
1896         hardware instead of checking it using ls.  configure.in should
1897         have taken care of any problems.
1898         (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
1899
1900 Mon Jul 22 22:38:59 1996  Andrew Cagney  <cagney@highland.com.au>
1901
1902         * psim.c (psim_options): Enter the argument to the memory size
1903         option directly into the device tree.  Was using atol() which is
1904         dangerously non portable.
1905
1906 Mon Jul 22 22:17:08 1996  Andrew Cagney  <cagney@highland.com.au>
1907
1908         * configure.in (icache): Extend icache flag to include an insn
1909         option.  If specifyed the insn - aka instruction - is included in

1912
1913         * igen.c (main), igen.h: Add option -S - inSn - for specifying

1926
1927         * emul_generic.c (emul_add_tree_options): Was incorrectly setting
1928         the strict-alignment option when hardwired for non-strict
1929         alignment.
1930
1931 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

1933         * gen-semantics.c: Make the my_index variable a macro MY_INDEX.
1934
1935         * ppc-instructions: Adjust so that references are to MY_INDEX and
1936         not my_index.
1937
1938 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1939
1940         * gen-idecode.c: Output the complete run_until_stop function
1941         instead of just the code to handle a single instruction issue.
1942         * : Have the generated idecode.c include inline.c (instead of psim.c).
1943
1944         * std-config.h: Change psim.c so that it isn't inlined (as this is
1945         no longer needed).
1946
1947         * psim.c (run_until_stop): Delete the old run_until_stop function
1948         instead calling the idecode_run and idecode_run_until_stop
1949         functions that gen-idecode.c is now creating.
1950
1951 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1952
1953         * dgen.c: Maintenance - update to use new features found in lf.c.

1959
1960         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
1961         eliminate trace statements.
1962

1970         current instructions name and source line number.
1971
1972         * gen-semantics.c, gen-icache.c: Adjust generated ITRACE calls to
1973         match new interface.

1976         corresponding call to ITRACE so that it still matches.
1977
1978         * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
1979         of ITRACE.  The CPP line directives would have previously set the
1980         line-nr and file name so ITRACE isn't needed.
1981
1982 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1983
1984         * gen-idecode.c (print_jump_until_stop_body): New function and
1985         idecode generation option.  Instead of generating and calling
1986         separate functions containing the semantic and icache code
1987         generate a single monolythic function and use goto's (and GCC's
1988         indirect jump) to move between code blocks.
1989
1990         * Makefile.in: Add sim_jump flag to those passed to igen.
1991
1992         * configure.in: New option --enable-sim-jump (default disabled)
1993
1994         * ppc-instructions: Eliminate any uses of labels and goto's.
1995         These result in duplicate declarations when a single flat function
1996         is being create.
1997
1998         * ppc-opcode-jump: New file.  Set of opcode rules useful when
1999         testing jumping idecodes.

2002
2003         * gen-idecode.c: Optionally include the semantic code for an
2004         instruction in the function that is doing the decoding.
2005
2006         * igen.c: Add option (-C) to generate semantics in the instruction
2007         decode functions.
2008
2009         * configure.in (--enable-sim-icache): Accept an option list such
2010         as 1024,define.  Add a new choice to the list - semantic - which
2011         will cause igen to generate instruction decode functions that
2012         include the corresponding semantic code.
2013

2017         Enable/disable the inclusion of CPP line directives in the
2018         generated files.  Such directives refer back to the source files
2019         used when generating the simulator code.
2020
2021         * Makefile.in (sim_line_nr): Pass to igen.
2022
2023 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2024
2025         * igen.c (main): Revamp the options so that more letters are
2026         available.
2027
2028         * configure.in: Adjust to match igen's revamped options
2029
2030 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
2031
2032         * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2033         that they use the same technique as igen (ie a dummy targets
2034         tmp-pk and tmp-hw are created).
2035
2036 Mon Jun 24 22:28:00 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

2070         * igen.c: Remove the opcode filter table loading code.
2071         * Makefile.in (filter.o): Adjust
2072         * configure.in: Adjust filter flag so that default includes 32bit
2073         and floating point.
2074         * ppc-instructions: Clean up filter fields so that only in use

2100
2101         * device_table.h: Don't pass the parent device into a devices
