 386
 387         * std-config.h (SEMANTICS_INLINE): By default, mask out the
 388         inlining of semantic functions from DEFAULT_INLINE.  Almost all
 389         configurations call the semantic code via a pointer so there is
 390         little benefit.
 391
 392         * std-config.h (ICACHE_INLINE): Ditto.
 393

 417 Wed Jul 24 15:47:09 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 418
 419         * gen-icache.c (print_icache_function): Have the cache function
 420         always update the cache_entries semantic and address fields.
 421
 422         * gen-idecode.c (print_idecode_switch_illegal): Include a break
 423         when generating illegal instructions.  This was commented out
 424         which is a hangover from looking a at switch statements generated
 425         using indirect jumps.
 426
 427 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 428
 429         * igen.c (print_my_defines): Replaces print_define_my_index.

 431         * gen-icache.c (print_icache_function): Adjust.
 432         * gen-idecode.c (print_jump_insn): Adjust.

 434
 435         * gen-support.c (gen_support_h): Add optional include to created
 436         support.h so that, like cpu, it is optionally inlined for all
 437         modules that include it.
 438         * inline.h, inline.c: Adjust so that support.[hc] is handled the
 439         same as cpu.[hc].
 440
 441         * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
 442         name for a lable and then branch to it.

 445         Single-Precision, Floating Convert from Integer Doubleword): Use
 446         LABEL and GOTO instead of the recently added switch statements.
 447

 449
 450         * gen-idecode.c (print_run_until_stop_body): Too many rparen in
 451         generated code.
 452
 453 Tue Jul 23 20:57:01 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

 456         * (--enable-sim-inline): Reorder patern matching of arguments so
 457         that SUPPORT=ALL_INLINE is reconized as *=* and not *_INLINE.

 459         * configure: rebuild.
 460
 461 Mon Jul 22 23:25:08 1996  Andrew Cagney  <cagney@highland.com.au>
 462
 463         * configure.in (--enable-sim-hardware, --enable-sim-packages): New
 464         configuration options.  Let the user specify the packages or
 465         hardware devices that are to be included in the build.  Makes it
 466         possible for user packages to be specified.
 467
 468         * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
 469         hardware instead of checking it using ls.  configure.in should
 470         have taken care of any problems.
 471         (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
 472
 473 Mon Jul 22 22:38:59 1996  Andrew Cagney  <cagney@highland.com.au>
 474
 475         * psim.c (psim_options): Enter the argument to the memory size
 476         option directly into the device tree.  Was using atol() which is
 477         dangerously non portable.
 478
 479 Mon Jul 22 22:17:08 1996  Andrew Cagney  <cagney@highland.com.au>
 480
 481         * configure.in (icache): Extend icache flag to include an insn
 482         option.  If specifyed the insn - aka instruction - is included in

 484         * configure: re-generate.
 485
 486         * igen.c (main), igen.h: Add option -S - inSn - for specifying

 499
 500         * emul_generic.c (emul_add_tree_options): Was incorrectly setting
 501         the strict-alignment option when hardwired for non-strict
 502         alignment.
 503
 504 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

 509         not my_index.
 510
 511 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 512
 513         * gen-idecode.c: Output the complete run_until_stop function
 514         instead of just the code to handle a single instruction issue.
 515         * : Have the generated idecode.c include inline.c (instead of psim.c).
 516
 517         * std-config.h: Change psim.c so that it isn't inlined (as this is
 518         no longer needed).
 519
 520         * psim.c (run_until_stop): Delete the old run_until_stop function
 521         instead calling the idecode_run and idecode_run_until_stop
 522         functions that gen-idecode.c is now creating.
 523
 524 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 525
 526         * dgen.c: Maintenance - update to use new features found in lf.c.

 530
 531 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 532
 533         * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
 534         eliminate trace statements.
 535
 536         * debug.c: Change trace format so that it is consistent
 537         (file:line-nr) with CC's error output.

 549         corresponding call to ITRACE so that it still matches.
 550
 551         * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
 552         of ITRACE.  The CPP line directives would have previously set the
 553         line-nr and file name so ITRACE isn't needed.
 554
 555 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 556
 557         * gen-idecode.c (print_jump_until_stop_body): New function and
 558         idecode generation option.  Instead of generating and calling
 559         separate functions containing the semantic and icache code
 560         generate a single monolythic function and use goto's (and GCC's
 561         indirect jump) to move between code blocks.
 562
 563         * Makefile.in: Add sim_jump flag to those passed to igen.
 564
 565         * configure.in: New option --enable-sim-jump (default disabled)
 566
 567         * ppc-instructions: Eliminate any uses of labels and goto's.

 569         is being create.
 570
 571         * ppc-opcode-jump: New file.  Set of opcode rules useful when
 572         testing jumping idecodes.

 577         instruction in the function that is doing the decoding.
 578
 579         * igen.c: Add option (-C) to generate semantics in the instruction
 580         decode functions.
 581
 582         * configure.in (--enable-sim-icache): Accept an option list such
 583         as 1024,define.  Add a new choice to the list - semantic - which
 584         will cause igen to generate instruction decode functions that
 585         include the corresponding semantic code.
 586
 587 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

 592         used when generating the simulator code.
 593
 594         * Makefile.in (sim_line_nr): Pass to igen.
 595
 596 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 597
 598         * igen.c (main): Revamp the options so that more letters are
 599         available.
 600
 601         * configure.in: Adjust to match igen's revamped options
 602
 603 Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
 604
 605         * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
 606         that they use the same technique as igen (ie a dummy targets
 607         tmp-pk and tmp-hw are created).
 608
 609 Mon Jun 24 22:28:00 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>

 644         * Makefile.in (filter.o): Adjust
 645         * configure.in: Adjust filter flag so that default includes 32bit

 673
 674         * device_table.h: Don't pass the parent device into a devices

1510         trace_dump_device_tree.  The first is a replacement for the
1511         variable `print_info' found in main.c and sim_calls.c.  The latter
1512         two enable the dumping of the entire device tree.
1513
1514         * debug.c: Add to trace_description table.
1515
1516         * main.c (main): Use above trace instead of local variable

1595
1596         * emul_generic.c (emul_write_buffer): Use vm faulting byte
1597         read/write calls for buffer transfers.  This will cause a fault to
