   2
   3         * configure.in: Test whether /dev/zero works on the system, and if
   4         it does, define HAVE_DEVZERO.
   5         * configure: Regenerate.
   6
   7         * emul_generic.c (emul_add_tree_hardware): Do not add /iobus/disk
   8         if we don't have a working /dev/zero on the system.

  37
  38         * device_table.h (device_instance_callbacks): Relace the claim and

  47
  48         * emul_chirp.c (chirp_emul_call_method): Use the new device
  49         instance call method and let that handle a client claim call.
  50
  51         * hw_htab.c (claim_memory): Wrapper function to call the memory
  52         devices "claim" method using the new device-instance call-method

  59         (hw_memory_instance_release): Ditto.
  60         (hw_memory_instance_methods): New table of memory specific
  61         methods claim and release.  Add to the hw_memory_callback

  88
  89         * std-config.h (CURRENT_STDIO, current_stdio): New macro. Set up
  90         stdio configuration so that it works in the same way as the rest
  91         of the simulation.
  92         * psim.c (psim_create): Initialize current_stdio from the device
  93         tree.
  94         * emul_generic.c (emul_add_tree_options): Enter a default value

 102         startup when the processor was still undefined.
 103         (print_jump): For safety, restart smp loop when cpu_nr >= nr_cpus,
 104         not just equal.

 113
 114         * ppc-cache-rules (cache): Change RS and RB to cache instead of
 115         compute.  The block move instructions use them.

 117         * idecode_expression.h (FPSCR_SET): New macro, set specific FPSCR
 118         register.
 119         (CR_FIELD): New macro, extract specific CR register.

 147
 148         * std-config.h (SEMANTICS_INLINE): By default, mask out the
 149         inlining of semantic functions from DEFAULT_INLINE.  Almost all
 150         configurations call the semantic code via a pointer so there is
 151         little benefit.
 152
 153         * std-config.h (ICACHE_INLINE): Ditto.
 154
 155 Thu Jul 25 20:07:30 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

 174         * gen-idecode.c (print_run_until_stop_body): Only generate loop
 175         termination test if creating idecode_run_until_stop.  Push the
 176         loop termination test back into each alternative branch.
 177
 178 Wed Jul 24 15:47:09 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 179
 180         * gen-icache.c (print_icache_function): Have the cache function
 181         always update the cache_entries semantic and address fields.
 182
 183         * gen-idecode.c (print_idecode_switch_illegal): Include a break
 184         when generating illegal instructions.  This was commented out
 185         which is a hangover from looking a at switch statements generated
 186         using indirect jumps.
 187
 188 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 189
 190         * igen.c (print_my_defines): Replaces print_define_my_index.
 191         Print both a definition for MY_INDEX and MY_PREFIX.
 192         * gen-icache.c (print_icache_function): Adjust.
 193         * gen-idecode.c (print_jump_insn): Adjust.
 194         * gen-semantics.c (print_c_semantic): Adjust.
 195
 196         * gen-support.c (gen_support_h): Add optional include to created
 197         support.h so that, like cpu, it is optionally inlined for all
 198         modules that include it.
 199         * inline.h, inline.c: Adjust so that support.[hc] is handled the
 200         same as cpu.[hc].
 201
 202         * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
 203         name for a lable and then branch to it.
 204
 205         * ppc-instructions (convert_to_integer, Floating Round to
 206         Single-Precision, Floating Convert from Integer Doubleword): Use
 207         LABEL and GOTO instead of the recently added switch statements.
 208
 209 Wed Jul 24 14:02:42 1996  Andrew Cagney  <cagney@sawnoff.highland.com.au>
 210
 211         * gen-idecode.c (print_run_until_stop_body): Too many rparen in
 212         generated code.
 213
 214 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 215
 216         * configure.in (--enable-sim-line-nr): Typo - sim_line-nr.
 217         * (--enable-sim-inline): Reorder patern matching of arguments so
 218         that SUPPORT=ALL_INLINE is reconized as *=* and not *_INLINE.

 220         * configure: rebuild.
 221
 222 Mon Jul 22 23:25:08 1996  Andrew Cagney  <cagney@highland.com.au>
 223
 224         * configure.in (--enable-sim-hardware, --enable-sim-packages): New
 225         configuration options.  Let the user specify the packages or
 226         hardware devices that are to be included in the build.  Makes it
 227         possible for user packages to be specified.
 228
 229         * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
 230         hardware instead of checking it using ls.  configure.in should
 231         have taken care of any problems.
 232         (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
 233
 234 Mon Jul 22 22:38:59 1996  Andrew Cagney  <cagney@highland.com.au>
 235
 236         * psim.c (psim_options): Enter the argument to the memory size
 237         option directly into the device tree.  Was using atol() which is
 238         dangerously non portable.
 239
 240 Mon Jul 22 22:17:08 1996  Andrew Cagney  <cagney@highland.com.au>
 241
 242         * configure.in (icache): Extend icache flag to include an insn
 243         option.  If specifyed the insn - aka instruction - is included in
 244         the instruction cache.  Make this the default.
 245         * configure: re-generate.
 246
 247         * igen.c (main), igen.h: Add option -S - inSn - for specifying
 248         that the instruction should be included in the icache.
 249
 250         * gen-icache.c (print_icache_body): If enabled, output code to put

 256         * Makefile.in (BUILD_CFLAGS): Include -g when building the
 257         generators.
 258

 260
 261         * emul_generic.c (emul_add_tree_options): Was incorrectly setting
 262         the strict-alignment option when hardwired for non-strict
 263         alignment.
 264
 265 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 266
 267         * gen-semantics.c: Make the my_index variable a macro MY_INDEX.
 268
 269         * ppc-instructions: Adjust so that references are to MY_INDEX and
 270         not my_index.
 271
 272 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 273
 274         * gen-idecode.c: Output the complete run_until_stop function
 275         instead of just the code to handle a single instruction issue.
 276         * : Have the generated idecode.c include inline.c (instead of psim.c).
 277
 278         * std-config.h: Change psim.c so that it isn't inlined (as this is
 279         no longer needed).
 280
 281         * psim.c (run_until_stop): Delete the old run_until_stop function
 282         instead calling the idecode_run and idecode_run_until_stop
 283         functions that gen-idecode.c is now creating.
 284
 285 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 286
 287         * dgen.c: Maintenance - update to use new features found in lf.c.
 288
 289         * filter_filename.c (filter_filename): Maintenance - make the
 290         string constant.
 291
 292 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 293
 294         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
 295         eliminate trace statements.
 296
 297         * debug.c: Change trace format so that it is consistent
 298         (file:line-nr) with CC's error output.
 299
 300         * gen-itable.c (itable_c_insn): Add the source file name and
 301         source line number to the instruction's informational entry.
 302
 303         * debug.c (ITRACE): Use the itable (and my_index) to get the
 304         current instructions name and source line number.
 305
 306         * gen-semantics.c, gen-icache.c: Adjust generated ITRACE calls to
 307         match new interface.
 308
 309         * emul_bugapi.c (emul_bugapi_instruction_call): Adjust
 310         corresponding call to ITRACE so that it still matches.
 311
 312         * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
 313         of ITRACE.  The CPP line directives would have previously set the
 314         line-nr and file name so ITRACE isn't needed.
 315
 316 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 317
 318         * gen-idecode.c (print_jump_until_stop_body): New function and
 319         idecode generation option.  Instead of generating and calling
 320         separate functions containing the semantic and icache code
 321         generate a single monolythic function and use goto's (and GCC's
 322         indirect jump) to move between code blocks.
 323
 324         * Makefile.in: Add sim_jump flag to those passed to igen.
 325
 326         * configure.in: New option --enable-sim-jump (default disabled)
 327
 328         * ppc-instructions: Eliminate any uses of labels and goto's.
 329         These result in duplicate declarations when a single flat function
 330         is being create.
 331
 332         * ppc-opcode-jump: New file.  Set of opcode rules useful when
 333         testing jumping idecodes.
 334
 335 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 336
 337         * gen-idecode.c: Optionally include the semantic code for an
 338         instruction in the function that is doing the decoding.
 339
 340         * igen.c: Add option (-C) to generate semantics in the instruction
 341         decode functions.
 342
 343         * configure.in (--enable-sim-icache): Accept an option list such
 344         as 1024,define.  Add a new choice to the list - semantic - which
 345         will cause igen to generate instruction decode functions that
 346         include the corresponding semantic code.
 347
 348 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 349
 350         * configure.in: New option --enable-sim-line-nr (default enabled).
 351         Enable/disable the inclusion of CPP line directives in the
 352         generated files.  Such directives refer back to the source files
 353         used when generating the simulator code.
 354
 355         * Makefile.in (sim_line_nr): Pass to igen.
 356
 357 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 358
 359         * igen.c (main): Revamp the options so that more letters are
 360         available.
 361
 362         * configure.in: Adjust to match igen's revamped options
 363
