   7
   8         * options.c (print_options): Print whether many of the
   9         configuration macros are defined.
  10
  11         * main.c (main): If -t options and no filename, just print the
  12         options, and don't print the usage message.

  15
  16         * configure.in: Test whether /dev/zero works on the system, and if
  17         it does, define HAVE_DEVZERO.
  18         * configure: Regenerate.
  19
  20         * emul_generic.c (emul_add_tree_hardware): Do not add /iobus/disk
  21         if we don't have a working /dev/zero on the system.

  60
  61         * emul_chirp.c (chirp_emul_call_method): Use the new device
  62         instance call method and let that handle a client claim call.
  63
  64         * hw_htab.c (claim_memory): Wrapper function to call the memory
  65         devices "claim" method using the new device-instance call-method

  72         (hw_memory_instance_release): Ditto.
  73         (hw_memory_instance_methods): New table of memory specific
  74         methods claim and release.  Add to the hw_memory_callback

 101
 102         * std-config.h (CURRENT_STDIO, current_stdio): New macro. Set up
 103         stdio configuration so that it works in the same way as the rest
 104         of the simulation.
 105         * psim.c (psim_create): Initialize current_stdio from the device
 106         tree.
 107         * emul_generic.c (emul_add_tree_options): Enter a default value

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

 126
 127         * ppc-cache-rules (cache): Change RS and RB to cache instead of
 128         compute.  The block move instructions use them.

 130         * idecode_expression.h (FPSCR_SET): New macro, set specific FPSCR
 131         register.
 132         (CR_FIELD): New macro, extract specific CR register.

 160
 161         * std-config.h (SEMANTICS_INLINE): By default, mask out the
 162         inlining of semantic functions from DEFAULT_INLINE.  Almost all
 163         configurations call the semantic code via a pointer so there is
 164         little benefit.
 165
 166         * std-config.h (ICACHE_INLINE): Ditto.
 167
 168 Thu Jul 25 20:07:30 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

 187         * gen-idecode.c (print_run_until_stop_body): Only generate loop
 188         termination test if creating idecode_run_until_stop.  Push the
 189         loop termination test back into each alternative branch.
 190
 191 Wed Jul 24 15:47:09 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 192
 193         * gen-icache.c (print_icache_function): Have the cache function
 194         always update the cache_entries semantic and address fields.
 195
 196         * gen-idecode.c (print_idecode_switch_illegal): Include a break
 197         when generating illegal instructions.  This was commented out
 198         which is a hangover from looking a at switch statements generated
 199         using indirect jumps.
 200
 201 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 202
 203         * igen.c (print_my_defines): Replaces print_define_my_index.
 204         Print both a definition for MY_INDEX and MY_PREFIX.
 205         * gen-icache.c (print_icache_function): Adjust.
 206         * gen-idecode.c (print_jump_insn): Adjust.
 207         * gen-semantics.c (print_c_semantic): Adjust.
 208
 209         * gen-support.c (gen_support_h): Add optional include to created
 210         support.h so that, like cpu, it is optionally inlined for all
 211         modules that include it.
 212         * inline.h, inline.c: Adjust so that support.[hc] is handled the
 213         same as cpu.[hc].
 214
 215         * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
 216         name for a lable and then branch to it.
 217
 218         * ppc-instructions (convert_to_integer, Floating Round to
 219         Single-Precision, Floating Convert from Integer Doubleword): Use
 220         LABEL and GOTO instead of the recently added switch statements.
 221
 222 Wed Jul 24 14:02:42 1996  Andrew Cagney  <cagney@sawnoff.highland.com.au>
 223
 224         * gen-idecode.c (print_run_until_stop_body): Too many rparen in
 225         generated code.
 226
 227 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 228
 229         * configure.in (--enable-sim-line-nr): Typo - sim_line-nr.
 230         * (--enable-sim-inline): Reorder patern matching of arguments so
 231         that SUPPORT=ALL_INLINE is reconized as *=* and not *_INLINE.
 232
 233         * configure: rebuild.
 234
 235 Mon Jul 22 23:25:08 1996  Andrew Cagney  <cagney@highland.com.au>
 236
 237         * configure.in (--enable-sim-hardware, --enable-sim-packages): New
 238         configuration options.  Let the user specify the packages or
 239         hardware devices that are to be included in the build.  Makes it
 240         possible for user packages to be specified.
 241
 242         * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
 243         hardware instead of checking it using ls.  configure.in should
 244         have taken care of any problems.
 245         (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
 246
 247 Mon Jul 22 22:38:59 1996  Andrew Cagney  <cagney@highland.com.au>
 248
 249         * psim.c (psim_options): Enter the argument to the memory size
 250         option directly into the device tree.  Was using atol() which is
 251         dangerously non portable.
 252
 253 Mon Jul 22 22:17:08 1996  Andrew Cagney  <cagney@highland.com.au>
 254
 255         * configure.in (icache): Extend icache flag to include an insn
 256         option.  If specifyed the insn - aka instruction - is included in
 257         the instruction cache.  Make this the default.
 258         * configure: re-generate.
 259
 260         * igen.c (main), igen.h: Add option -S - inSn - for specifying
 261         that the instruction should be included in the icache.
 262
 263         * gen-icache.c (print_icache_body): If enabled, output code to put

 266
 267 Mon Jul 22 20:46:12 1996  Andrew Cagney  <cagney@highland.com.au>

 269         * Makefile.in (BUILD_CFLAGS): Include -g when building the
 270         generators.
 271
 272 Mon Jul 22 20:00:25 1996  Andrew Cagney  <cagney@highland.com.au>
 273
 274         * emul_generic.c (emul_add_tree_options): Was incorrectly setting
 275         the strict-alignment option when hardwired for non-strict
 276         alignment.
 277
 278 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 279
 280         * gen-semantics.c: Make the my_index variable a macro MY_INDEX.
 281
 282         * ppc-instructions: Adjust so that references are to MY_INDEX and
 283         not my_index.
 284
 285 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 286
 287         * gen-idecode.c: Output the complete run_until_stop function
 288         instead of just the code to handle a single instruction issue.
 289         * : Have the generated idecode.c include inline.c (instead of psim.c).
 290
 291         * std-config.h: Change psim.c so that it isn't inlined (as this is
 292         no longer needed).
 293
 294         * psim.c (run_until_stop): Delete the old run_until_stop function
 295         instead calling the idecode_run and idecode_run_until_stop
 296         functions that gen-idecode.c is now creating.
 297
 298 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 299
 300         * dgen.c: Maintenance - update to use new features found in lf.c.
 301
 302         * filter_filename.c (filter_filename): Maintenance - make the
 303         string constant.
 304
 305 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 306
 307         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
 308         eliminate trace statements.
 309
 310         * debug.c: Change trace format so that it is consistent
 311         (file:line-nr) with CC's error output.
 312
 313         * gen-itable.c (itable_c_insn): Add the source file name and
 314         source line number to the instruction's informational entry.
 315
 316         * debug.c (ITRACE): Use the itable (and my_index) to get the
 317         current instructions name and source line number.
 318
 319         * gen-semantics.c, gen-icache.c: Adjust generated ITRACE calls to
 320         match new interface.
 321
 322         * emul_bugapi.c (emul_bugapi_instruction_call): Adjust
 323         corresponding call to ITRACE so that it still matches.
 324
 325         * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
 326         of ITRACE.  The CPP line directives would have previously set the
 327         line-nr and file name so ITRACE isn't needed.
 328
 329 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 330
 331         * gen-idecode.c (print_jump_until_stop_body): New function and
 332         idecode generation option.  Instead of generating and calling
 333         separate functions containing the semantic and icache code
 334         generate a single monolythic function and use goto's (and GCC's
 335         indirect jump) to move between code blocks.
 336
 337         * Makefile.in: Add sim_jump flag to those passed to igen.
 338
 339         * configure.in: New option --enable-sim-jump (default disabled)
 340
 341         * ppc-instructions: Eliminate any uses of labels and goto's.
 342         These result in duplicate declarations when a single flat function
 343         is being create.
 344
 345         * ppc-opcode-jump: New file.  Set of opcode rules useful when
 346         testing jumping idecodes.
 347
 348 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 349
 350         * gen-idecode.c: Optionally include the semantic code for an
 351         instruction in the function that is doing the decoding.
 352
 353         * igen.c: Add option (-C) to generate semantics in the instruction
 354         decode functions.
 355
 356         * configure.in (--enable-sim-icache): Accept an option list such
 357         as 1024,define.  Add a new choice to the list - semantic - which
 358         will cause igen to generate instruction decode functions that
 359         include the corresponding semantic code.
 360
 361 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 362
 363         * configure.in: New option --enable-sim-line-nr (default enabled).
