  22         of ppc-opcode-.
  23
  24 Wed Feb 12 19:33:45 1997  Andrew Cagney  <cagney@phydeaux.cygnus.com>
  25
  26         * Many of the ppc-opcode-* files are identical baring the type of
  27         lookup table.  Instead of having multiple tables, igen can do this
  28         via an additional option.
  29
  30         * ld-decode.h, ld-decode.c (force_decode_gen_type): New function,
  31         allow the type of generated table specified in the decode file to
  32         be overridden.
  33
  34         * ld-decode.c (load_decode_table): Allow the table type to be
  35         overridden.

  43         configure script.
  44         * configure: Regenerate.
  45
  46 Tue Feb 11 13:49:10 1997  Michael Meissner  <meissner@tiktok.cygnus.com>
  47
  48         * events.c (event_queue_create): Don't use NULL to initialize an
  49         integer field.

  51         of sigprocmask to appropriate autoconf test.
  52
  53         * main.c ({cntrl_c,main}): Use RETSIGTYPE for signal return type,
  54         don't assume void.
  55         * sim_calls.c (sim_{ctrl_c,resume}): Ditto.
  56
  57         * Makefile.in (callback.o): Define HAVE_CONFIG_H, so callback.c
  58         includes our config.h.
  59

  61
  62         * configure.in: Fix typo in test for callback.c.
  63         * configure: Regenerated.
  64
  65 Fri Feb  7 10:04:25 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
  66
  67         * emul_chirp.c (emul_chirp_create): Handle a virtbase of -1 being
  68         found in the device tree.
  69
  70 Wed Feb  5 10:56:27 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
  71
  72         * Property create/initialization still wasn't correctly ordered.
  73         Should be delaying everything related to ihandle creation until
  74         after the rest of the tree has been established.
  75
  76         * device.c (device_find_ihandle_runtime_property): Update.
  77         (device_add_ihandle_runtime_property): Update.
  78
  79         * tree.c (parse_ihandle_property): Delay lookup of the device to
  80         be opened until the ihandle initialization phase.
  81         * tree.c (print_properties): Update.
  82
  83 Wed Feb  5 10:56:27 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
  84
  85         * gen-icache.c (print_icache_extraction): Add a reason parameter.
  86         Augment each extracted field with a comment citing the codes
  87         origin.  Should simplify tracking down incorrect cache
  88         extractions.
  89
  90 Tue Feb  4 17:44:51 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
  91
  92         * gen-icache.c: Generalize code handling XXX_is_NNN so that it
  93         works for normal and boolean table entries.
  94
  95         * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
  96         valid.  Handle this just like *_{read,write}_register now handles
  97         it.
  98
  99 Mon Feb  3 17:18:16 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 100
 101         * events.c (insert_event_entry): Correct loop termination
 102         assertions.
 103
 104 Fri Jan 31 16:20:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 105
 106         * psim.c (psim_options): Add new option -c for max-iterations or
 107         count.
 108         (psim_usage): Document.
 109         (psim_max_iterations_exceeded): New function, abort simulation if
 110         max iterations exceeded.
 111
 112         * gen-idecode.c: Re-work the table lookup code so that it assumes
 113         that the entry is a leaf by default.  Simplify the boolean table
 114         entry code so that it involves a mask + test instead of shift +
 115         shift + mask + test.
 116
 117         * gen-idecode.c: Correct generated igen body so that it no drops
 118         or doubles clock interrupts.
 119
 120
 121 Thu Jan 30 11:23:20 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 122

 127         if common callback is present.
 128
 129 Wed Jan 29 12:32:41 1997  Michael Meissner  <meissner@tiktok.cygnus.com>
 130
 131         * configure.in (sim_callback): If the gdb is post 4.16, configure
 132         callback support from the common directory.
 133         * configure: Regenerate.
 134
 135         * Makefile.in (BUILT_SRC_WO_CONFIG): Add targ-vals.{h,def} and
 136         targ-map.c.
 137         (GDB_OBJ): Add callback support configured in.
 138         (gentmap,targ-vals.def): Build from common directory.
 139         (targ-vals.h,targ-map.c): Build by running gentmap.
 140         (callback.o): Build from source in common directory.
 141         (targ-map.o): Add dependency.
 142         (clean): Remove gentmap.
 143
 144 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 145
 146         * igen wasn't aborting if the opcode table contained no valid
 147         fields.
 148
 149         * misc.c (name2i): Possibly abort if an invalid name is
 150         encountered.
 151         * ld-decode.c: Abort if the table type isn't found.
 152
 153 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 154
 155         * When performance monitoring is disabled, it is still possible to
 156         determine the simulation speed by looking at the number of elapsed
 157         ticks recorded by the event queue.
 158
 159         * psim.c (psim_write_register, psim_read_register): Force the cpu
 160         to zero when it is either of `-1' or `nr_cpus'.  In both cases the
 161         next cpu would be zero any way.
 162
 163         * mon.c (mon_print_info): If possible, print the system cycle
 164         performance.  This is an indication of the number of instructions
 165         per second.
 166
 167 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 168
 169         * The code to allow an event queue to be updated during a signal
 170         was missing.  For main.c, a cntrl-c simulation termination wasn't
 171         handled cleanly.
 172
 173         * The simulation would not correctly restart if an event requested
 174         that the simulation be halted.
 175
 176         * psim.c (psim_options): Add hack to -i option to optionally
 177         include a level vis -i2.
 178         (psim_usage): Document.
 179
 180         * main.c (cntrl_c, cntrl_c_simulation): New functions.  When a
 181         cntrl-c occures schedule an event to halt the simulation.
 182         (main): Catch CNTRL-C signals with the function cntrl_c.
 183
 184         * events.c (event_queue_process): Mask interrupts while
 185         manipulating the async event queue.
 186         (event_queue_init): Ditto.
 187         (event_queue_schedule_after_signal): Ditto.
 188
 189         * events.c (event_queue_process): Mark the event queue as being in
 190         the processing state when processing has started.  Adjust code
 191         so that it is tolerant of halts.
 192         (event_queue_init): Start the event queue out with processing
 193         false.
 194         (event_queue_tick): Check that processing isn't still being
 195         performed.
 196
 197         * gen-idecode.c (print_run_until_stop_body): Call
 198         event_queue_process_events to clear possibly pending events before
 199         starting a simulation run.  Re-arange main loop so that simulator
 200         is correctly restarted when an event halts the simulation.
 201
 202         * psim.c (psim_halt): Handle an event halting the simulation.
 203         * psim.c (psim_init): Adjust initial cpu - == -1 - to match
 204         reworked idecode.
 205
 206 Wed Jan 29 12:14:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 207
 208         * ppc-opcode-complex: Correct typo - was expanding ORA instead of
 209         RA.  Based on instruction frequency stats, expand additional
 210         instructions.
 211         * ppc-instructions: Change all `RA == 0' to RA_is_0.
 212
 213         * ppc-opcode-stupid: Move all but the basic table in -complex into
 214         here.  Update to new format.
 215
 216         * Makefile.in (tmp-defines): New target. Force defines.h to always
 217         be built.  Hence get ppc-opcode-goto to build.
 218
 219 Tue Jan 28 13:00:19 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 220
 221         * hw_com.c (hw_com_instance_read, hw_com_instance_write):
 222         Implement.
 223
 224 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 225
 226         * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
 227         to be initialized independant of the rest of the simulation
 228         initalization.  Otherwize a trace option explictly set from gdb
 229         could be overridden by hw_trace.
 230
 231         * psim.c (psim_options): Clarify reason why the trace ioctl occures.
 232
 233         * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
 234         debug.c.  It could be much simpler.
 235
 236 Thu Jan 23 09:07:26 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 237
 238         * Some devices support removable media.  Add hooks to the disk
 239         device so that it supports this.
 240
 241         * device.c (device_add_string_array_property,
 242         device_find_string_array_property): New functions, manipulate
 243         properties containing an array of strings.
 244         (device_find_string_property): Allow a string array.
 245         (device_init_static_properties): Update.
 246         (device_init_runtime_properties): Update.
 247
 248         * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
 249         media.  If no file image is specified, use the next one in the
 250         image property list.
 251         (hw_disk_init_address): Change the file property so that it is a
 252         string array - use the first entry for the initial file image.
 253
 254         * tree.c (print_string_aray_property): New function - print a
 255         string array.
 256         (print_properties): Adjust.
 257         (print_string): Write a string, handling double quotes.
 258
 259         * device.h: Define an ioctl to `change-media' with an optional new
 260         media image.
 261
 262         * hw_disk.c: Allow floppy disk devices to be specified.
 263
 264         * psim.c (psim_command): New function, parse more complex psim
 265         commands such as "change-media" and "trace".
 266         * sim_calls.c (sim_do_command): Use.
 267
 268 Wed Jan 22 09:38:33 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 269
 270         * For expressions like (RA == 0) that are entered in to the cache
 271         as RA_is_0. If possible generate the result of the expression so
 272         that the compiler gets a better chance of eliminating dead
 273         branches.
 274
 275         * gen-icache.c (print_icache_extraction): For a cache entry of
 276         the form <name>_is_<const> where it is a boolean field, generate
 277         the result of the expression instead of the expression its self.
 278         (print_icache_body): Remove code that was looking for *_is_0 and
 279         then generating corresponding definitions.
 280
 281         * gen-icache.c (print_icache_struct): If there is no cache, do not
 282         output expressions in idecode.h file.
 283
 284         * gen-icache.c (print_icache_body): Output them here.
 285
 286         * ppc-opcode-complex: Clarify constant values for SPR==LR register
 287         expansion.
 288
 289         * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
 290
 291 Wed Jan 22 12:24:52 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 292
 293         * The code that put values in and extracted values from the cache
 294         was too compilicated.  The cache table did not allow values to be
 295         computed from cache entries.  #defines could only be used when a
 296         cache was present, remove the restriction.
 297
 298         * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
 299         scratch variable is defined when a cache entry is beinf
 300         filled. Change the definition of a COMPUTE variable to be defined
 301         when the cache entry is being used.
 302         * gen-icache.c: Update.
 303
 304         * ld-cache.h, ld-cache.c: Change field names so that their meaning
 305         is more obvious.  old_name->field_name, new_name->derived_name.
 306         * gen-icache.c: Update
 307
 308         * gen-icache.h, gen-icache.c (print_icache_body): Make the three
 309         different types of cache code - put into cache, extract from
 310         cache, no cache - an explicit argument to print_icache_body.
 311         * gen-icache.c (print_icache_extraction): Ditto.
 312
 313         * gen-semantics.c (print_c_semantic): Update use.
 314         * gen-idecode.c (print_jump_insn): Update use.
 315         * gen-icache.c (print_icache_function): Update use.
 316
 317         * igen.c (main): Change 'R' option so that it does not force the
 318         cache.
 319
 320         * configure.in (enable-sim-icache): Clarify description.  Make
 321         #define one of the defaults regardless of the cache.  Probably
 322         should revamp and add a separate option.
 323
 324 Tue Jan 21 13:26:10 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 325
 326         * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
 327         partition numbering.
 328         (pk_disklabel_create_instance): Partition 1..4 are valid - not
 329         1..3.
 330         (is_iso9660): New function, verify a CD9660 File system.
 331         (pk_disklabel_create_instance): Start expanding so that active
 332         partition selection is supported.
 333
 334 Mon Jan 20 11:20:15 1997  Andrew Cagney  <cagney@kremvax.tpgi.com.au>
 335
 336         * The cap object was retaining a reference to the instance of a
 337         device after it was deleted. Instead add and remove cap's from the
 338         cap db as they are created and deleted.  This ensuring that a
 339         capibility is only used during the lifetime of the corresponding
 340         object.
 341
 342         * cap.h, cap.c: Correct cap type - was signed32 should be
 343         signed_cell.
 344
 345         * cap.c (cap_add, cap_remove): New methods for cap object that
 346         allow the explicit addition and removal of internal objects that
 347         the cap knows about.
 348
 349         * cap.c (cap_init): Rewrite.  Verify that the only objects
 350         remaining in the cap data base are those that were entered first.
 351         Thse objects will be the permenant ones.
 352         * device.c (device_init_address): Remember to initialize the cap
 353         database.
 354
 355         * device.c (device_create_instance_from): Explicitly add device
 356         instances to the cap database.  Simplify create code.
 357         (device_instance_delete): Explicitly remove device instances from
 358         the cap database.
 359
 360         * device.c (device_create_from): Explicitly add a device to the
 361         cap data base.
 362
 363         * device.c (device_create_from): Always set the cap members.
 364

1600
1601         * std-config.h (SEMANTICS_INLINE): By default, mask out the
1602         inlining of semantic functions from DEFAULT_INLINE.  Almost all

1605
1606         * std-config.h (ICACHE_INLINE): Ditto.
1607

1635
1636         * gen-idecode.c (print_idecode_switch_illegal): Include a break
1637         when generating illegal instructions.  This was commented out
1638         which is a hangover from looking a at switch statements generated
1639         using indirect jumps.
1640
1641 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1642

1648
1649         * gen-support.c (gen_support_h): Add optional include to created

1652         * inline.h, inline.c: Adjust so that support.[hc] is handled the
1653         same as cpu.[hc].
1654
1655         * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
1656         name for a lable and then branch to it.
1657
1658         * ppc-instructions (convert_to_integer, Floating Round to
1659         Single-Precision, Floating Convert from Integer Doubleword): Use

1661
1662 Wed Jul 24 14:02:42 1996  Andrew Cagney  <cagney@sawnoff.highland.com.au>
1663

1673         * configure: rebuild.
1674
1675 Mon Jul 22 23:25:08 1996  Andrew Cagney  <cagney@highland.com.au>
1676
1677         * configure.in (--enable-sim-hardware, --enable-sim-packages): New
1678         configuration options.  Let the user specify the packages or
1679         hardware devices that are to be included in the build.  Makes it
1680         possible for user packages to be specified.
1681
1682         * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
1683         hardware instead of checking it using ls.  configure.in should
1684         have taken care of any problems.
1685         (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
1686
1687 Mon Jul 22 22:38:59 1996  Andrew Cagney  <cagney@highland.com.au>
1688
1689         * psim.c (psim_options): Enter the argument to the memory size
1690         option directly into the device tree.  Was using atol() which is
1691         dangerously non portable.
1692
1693 Mon Jul 22 22:17:08 1996  Andrew Cagney  <cagney@highland.com.au>
1694
1695         * configure.in (icache): Extend icache flag to include an insn
1696         option.  If specifyed the insn - aka instruction - is included in

1698         * configure: re-generate.
1699
1700         * igen.c (main), igen.h: Add option -S - inSn - for specifying

1713
1714         * emul_generic.c (emul_add_tree_options): Was incorrectly setting
1715         the strict-alignment option when hardwired for non-strict

1718 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1719
1720         * gen-semantics.c: Make the my_index variable a macro MY_INDEX.
1721
1722         * ppc-instructions: Adjust so that references are to MY_INDEX and
1723         not my_index.
1724
1725 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1726
1727         * gen-idecode.c: Output the complete run_until_stop function
1728         instead of just the code to handle a single instruction issue.
1729         * : Have the generated idecode.c include inline.c (instead of psim.c).
1730
1731         * std-config.h: Change psim.c so that it isn't inlined (as this is
1732         no longer needed).
1733
1734         * psim.c (run_until_stop): Delete the old run_until_stop function
1735         instead calling the idecode_run and idecode_run_until_stop
1736         functions that gen-idecode.c is now creating.
1737
1738 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1739
1740         * dgen.c: Maintenance - update to use new features found in lf.c.

1746
1747         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
1748         eliminate trace statements.
1749
1750         * debug.c: Change trace format so that it is consistent

1757         current instructions name and source line number.
1758
1759         * gen-semantics.c, gen-icache.c: Adjust generated ITRACE calls to

1763         corresponding call to ITRACE so that it still matches.
1764
1765         * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
1766         of ITRACE.  The CPP line directives would have previously set the
1767         line-nr and file name so ITRACE isn't needed.
1768
1769 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
1770
1771         * gen-idecode.c (print_jump_until_stop_body): New function and
1772         idecode generation option.  Instead of generating and calling
1773         separate functions containing the semantic and icache code
1774         generate a single monolythic function and use goto's (and GCC's
1775         indirect jump) to move between code blocks.
1776
1777         * Makefile.in: Add sim_jump flag to those passed to igen.
1778
1779         * configure.in: New option --enable-sim-jump (default disabled)
1780
1781         * ppc-instructions: Eliminate any uses of labels and goto's.
1782         These result in duplicate declarations when a single flat function
