  11
  12         * device_table.h (device_instance_callbacks): Relace the claim and
  13         release methods with a more general table mapping from method-name
  14         to method-function.
  15
  16         * device.c (device_instance_call_method): New function.  Implement
  17         the OpenBoot call-method client interface.  Attempts to locate the
  18         instances method in the callback table.
  19         (device_instance_claim, device_instance_release): Delete.
  20         Replaced with call-method and a lookup table.
  21
  22         * emul_chirp.c (chirp_emul_call_method): Use the new device
  23         instance call method and let that handle a client claim call.
  24
  25         * hw_htab.c (claim_memory): Wrapper function to call the memory
  26         devices "claim" method using the new device-instance call-method
  27         interface.  Replaces the previous direct calls to claim.
  28         (htab_map_region): Use claim_memory.
  29         (htab_init_data_callback): Ditto.
  30
  31         * hw_memory.c (hw_memory_instance_claim): Update function
  32         interface so that it is compatible with call-method.
  33         (hw_memory_instance_release): Ditto.
  34         (hw_memory_instance_methods): New table of memory specific
  35         methods claim and release.  Add to the hw_memory_callback
  36         table.
  37
  38 Tue Jul 30 21:26:14 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

  44
  45         * sim_callbacks.h (sim_io_printf_filtered): Replace
  46         printf_filtered with a local simulator specific version.  Add

  49         * sim_callbacks.h (sim_io_write_stdout, sim_io_read_stdin,
  50         sim_io_write_stderr): New functions.  Read / write to the
  51         simulations stdin and stdout and stderr interfaces.  Merge in code
  52         from hw_pal that previously handled async I/O.
  53         (sim_io_flush_stdoutput): Rename flush_stdoutput.  Add #define
  54         flush_stdoutput to simplify updating of existing code.

  57         hw_pal_instance_write_callback): Use the new sim_io functions.
  58
  59         * main.c: Implement standalone versions of the new sim_io
  60         functions.  Include support for async I/O.
  61         * sim_calls.c: Ditto.  This time using the gdb callback table.
  62
  63         * std-config.h (CURRENT_STDIO, current_stdio): New macro. Set up
  64         stdio configuration so that it works in the same way as the rest
  65         of the simulation.
  66         * psim.c (psim_create): Initialize current_stdio from the device
  67         tree.
  68         * emul_generic.c (emul_add_tree_options): Enter a default value

  72
  73         * gen-idecode.c (print_jump): Was always generating a jump back to
  74         idecode.  Only necessary at tail of semantic code.
  75         (print_jump): Was always setting the processor's cia, even during
  76         startup when the processor was still undefined.
  77         (print_jump): For safety, restart smp loop when cpu_nr >= nr_cpus,
  78         not just equal.
  79
  80         * options.c (print_options): Add printing of WITH_REGPARM and
  81         WITH_STDCALL.

  84         (disabled) values if not defined.
  85
  86 Fri Jul 26 00:36:35 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
  87
  88         * ppc-cache-rules (cache): Change RS and RB to cache instead of
  89         compute.  The block move instructions use them.
  90
  91         * idecode_expression.h (FPSCR_SET): New macro, set specific FPSCR
  92         register.
  93         (CR_FIELD): New macro, extract specific CR register.

 121
 122         * std-config.h (SEMANTICS_INLINE): By default, mask out the
 123         inlining of semantic functions from DEFAULT_INLINE.  Almost all
 124         configurations call the semantic code via a pointer so there is
 125         little benefit.
 126
 127         * std-config.h (ICACHE_INLINE): Ditto.
 128
 129 Thu Jul 25 20:07:30 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

 139
 140         * std-config.h (REGPARM): Extend construction of REGPARM macro so
 141         that it can include __stdcall__ function attribute.
 142
 143 Wed Jul 24 19:04:20 1996  Andrew Cagney  <cagney@sawnoff>
 144
 145         * options.c (print_options): Include SUPPORT_INLINE in information

 148         * gen-idecode.c (print_run_until_stop_body): Only generate loop
 149         termination test if creating idecode_run_until_stop.  Push the
 150         loop termination test back into each alternative branch.
 151
 152 Wed Jul 24 15:47:09 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 153
 154         * gen-icache.c (print_icache_function): Have the cache function
 155         always update the cache_entries semantic and address fields.
 156
 157         * gen-idecode.c (print_idecode_switch_illegal): Include a break
 158         when generating illegal instructions.  This was commented out
 159         which is a hangover from looking a at switch statements generated
 160         using indirect jumps.
 161
 162 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 163
 164         * igen.c (print_my_defines): Replaces print_define_my_index.
 165         Print both a definition for MY_INDEX and MY_PREFIX.
 166         * gen-icache.c (print_icache_function): Adjust.
 167         * gen-idecode.c (print_jump_insn): Adjust.
 168         * gen-semantics.c (print_c_semantic): Adjust.
 169
 170         * gen-support.c (gen_support_h): Add optional include to created
 171         support.h so that, like cpu, it is optionally inlined for all
 172         modules that include it.
 173         * inline.h, inline.c: Adjust so that support.[hc] is handled the
 174         same as cpu.[hc].
 175
 176         * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
 177         name for a lable and then branch to it.
 178
 179         * ppc-instructions (convert_to_integer, Floating Round to
 180         Single-Precision, Floating Convert from Integer Doubleword): Use
 181         LABEL and GOTO instead of the recently added switch statements.
 182
 183 Wed Jul 24 14:02:42 1996  Andrew Cagney  <cagney@sawnoff.highland.com.au>
 184
 185         * gen-idecode.c (print_run_until_stop_body): Too many rparen in
 186         generated code.
 187
 188 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 189
 190         * configure.in (--enable-sim-line-nr): Typo - sim_line-nr.
 191         * (--enable-sim-inline): Reorder patern matching of arguments so
 192         that SUPPORT=ALL_INLINE is reconized as *=* and not *_INLINE.
 193
 194         * configure: rebuild.
 195
 196 Mon Jul 22 23:25:08 1996  Andrew Cagney  <cagney@highland.com.au>
 197
 198         * configure.in (--enable-sim-hardware, --enable-sim-packages): New
 199         configuration options.  Let the user specify the packages or
 200         hardware devices that are to be included in the build.  Makes it
 201         possible for user packages to be specified.
 202
 203         * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
 204         hardware instead of checking it using ls.  configure.in should
 205         have taken care of any problems.
 206         (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
 207
 208 Mon Jul 22 22:38:59 1996  Andrew Cagney  <cagney@highland.com.au>
 209
 210         * psim.c (psim_options): Enter the argument to the memory size
 211         option directly into the device tree.  Was using atol() which is
 212         dangerously non portable.
 213
 214 Mon Jul 22 22:17:08 1996  Andrew Cagney  <cagney@highland.com.au>
 215
 216         * configure.in (icache): Extend icache flag to include an insn
 217         option.  If specifyed the insn - aka instruction - is included in
 218         the instruction cache.  Make this the default.
 219         * configure: re-generate.
 220
 221         * igen.c (main), igen.h: Add option -S - inSn - for specifying
 222         that the instruction should be included in the icache.
 223
 224         * gen-icache.c (print_icache_body): If enabled, output code to put
 225         the instruction into the icache.

 227
 228 Mon Jul 22 20:46:12 1996  Andrew Cagney  <cagney@highland.com.au>

 230         * Makefile.in (BUILD_CFLAGS): Include -g when building the
 231         generators.
 232
 233 Mon Jul 22 20:00:25 1996  Andrew Cagney  <cagney@highland.com.au>
 234
 235         * emul_generic.c (emul_add_tree_options): Was incorrectly setting
 236         the strict-alignment option when hardwired for non-strict
 237         alignment.
 238
 239 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 240
 241         * gen-semantics.c: Make the my_index variable a macro MY_INDEX.
 242
 243         * ppc-instructions: Adjust so that references are to MY_INDEX and
 244         not my_index.
 245
 246 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 247
 248         * gen-idecode.c: Output the complete run_until_stop function
 249         instead of just the code to handle a single instruction issue.
 250         * : Have the generated idecode.c include inline.c (instead of psim.c).
 251
 252         * std-config.h: Change psim.c so that it isn't inlined (as this is
 253         no longer needed).
 254
 255         * psim.c (run_until_stop): Delete the old run_until_stop function
 256         instead calling the idecode_run and idecode_run_until_stop
 257         functions that gen-idecode.c is now creating.
 258
 259 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 260
 261         * dgen.c: Maintenance - update to use new features found in lf.c.
 262
 263         * filter_filename.c (filter_filename): Maintenance - make the
 264         string constant.
 265
 266 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 267
 268         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
 269         eliminate trace statements.
 270
 271         * debug.c: Change trace format so that it is consistent
 272         (file:line-nr) with CC's error output.

 277         * debug.c (ITRACE): Use the itable (and my_index) to get the
 278         current instructions name and source line number.
 279
 280         * gen-semantics.c, gen-icache.c: Adjust generated ITRACE calls to
 281         match new interface.
 282
 283         * emul_bugapi.c (emul_bugapi_instruction_call): Adjust
 284         corresponding call to ITRACE so that it still matches.
 285
 286         * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
 287         of ITRACE.  The CPP line directives would have previously set the
 288         line-nr and file name so ITRACE isn't needed.
 289
 290 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 291
 292         * gen-idecode.c (print_jump_until_stop_body): New function and
 293         idecode generation option.  Instead of generating and calling
 294         separate functions containing the semantic and icache code
 295         generate a single monolythic function and use goto's (and GCC's
 296         indirect jump) to move between code blocks.
 297
 298         * Makefile.in: Add sim_jump flag to those passed to igen.
 299
 300         * configure.in: New option --enable-sim-jump (default disabled)
 301
 302         * ppc-instructions: Eliminate any uses of labels and goto's.
 303         These result in duplicate declarations when a single flat function
 304         is being create.
 305
 306         * ppc-opcode-jump: New file.  Set of opcode rules useful when
 307         testing jumping idecodes.
 308
 309 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 310
 311         * gen-idecode.c: Optionally include the semantic code for an
 312         instruction in the function that is doing the decoding.
 313
 314         * igen.c: Add option (-C) to generate semantics in the instruction
 315         decode functions.
 316
 317         * configure.in (--enable-sim-icache): Accept an option list such
 318         as 1024,define.  Add a new choice to the list - semantic - which
 319         will cause igen to generate instruction decode functions that
 320         include the corresponding semantic code.
 321
 322 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 323
 324         * configure.in: New option --enable-sim-line-nr (default enabled).
 325         Enable/disable the inclusion of CPP line directives in the
 326         generated files.  Such directives refer back to the source files
 327         used when generating the simulator code.
 328
 329         * Makefile.in (sim_line_nr): Pass to igen.
 330
 331 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 332
 333         * igen.c (main): Revamp the options so that more letters are
 334         available.
 335
 336         * configure.in: Adjust to match igen's revamped options
 337
 338 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 339
 340         * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
 341         that they use the same technique as igen (ie a dummy targets
 342         tmp-pk and tmp-hw are created).
 343
 344 Mon Jun 24 22:28:00 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 345
 346         * Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.
 347
 348 Wed Jun 19 21:45:28 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 349
 350         * ld-cache.[hc], ld-decode.[hc], ld-insn.[hc]: New files. Separate
 351         out the loading of each of the tables from the rest of igen.
 352         * Makefile.in: Adjust.
 353         * igen.c: Adjust.
 354
 355         * gen-icache.[hc], gen-idecode.[hc], gen-itable.[hc],
 356         gen-model.[hc], gen-semantics.[hc]: New files. Separate out the
 357         code creating each separate set of generated files.
 358         * Makefile.in: Adjust.
 359         * igen.c: Adjust.
 360
 361         * gen-support.[ch]: New files. Output the support functions (found
 362         in the ppc-instructions file) into a separate file.
 363         * Makefile.in: Add.
 364         * inline.h, inline.c: Add.
