 384         (print_icache_internal_function_definition): Update.
 385
 386         * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
 387         files, will at some stage need to move it into support.
 388
 389         * igen.h, igen.c (main): New option -e <engine> - generate a full
 390         simulation engine.  Previously this was the -d <idecode-file>
 391         option.
 392         * gen-engine.h, gen-engine.c: Copies of gen-idecode.*.  Will need
 393         to clean these up so that that call upon the updated gen-idecode
 394         code.
 395
 396         * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
 397         generating a decode table.
 398
 399         * Makefile.in (igen): Add dependencies for new gen-engine.* files.
 400
 401         * igen.h, igen.c (main): New option -M - Control what is returned
 402         by semantic functions - -1/NIA vs CIA+N/NIA.  Add
 403         generate_semantic_returning_modified_nia_only to igen_code enum.
 404         * gen-semantics.c (print_semantic_body): As an alternative, make
 405         NIA == -1 instead of CIA+insn_size by default.
 406
 407         * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
 408         New option -P <prefix> - Prepend all generated functions with the
 409         specified prefix.
 410         (gen_idecode_c): Adjust.
 411         * gen-icache.c (print_icache_struct): Ditto.
 412         * gen-support.c (gen_support_c): Ditto.

 415
 416         * igen.c (main): Correct usage. Missleading message about ucase
 417         options dumping internal tables.  -F now includes rather then
 418         excludes instructions.
 419
 420         * misc.h, misc.c (a2i): Make 64bit.
 421
 422         * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
 423         max to 64bits, expect trouble.  Make the default 32 bits.
 424         * gen-idecode.c (print_idecode_table): Change EXTRACTED*
 425         et.al. macro's to use the insn_bit_size instead of assuming 32
 426         bits.
 427         * gen-icache.c (print_icache_extraction): Ditto.
 428         * gen-idecode.c (idecode_switch_start): Ditto.
 429         * gen-idecode.c (gen_idecode_c): Ditto
 430
 431         * igen.h (insn_specifying_widths), igen.c (main): New option -W.
 432         Indicates that the instruction field of the table is specifying
 433         bit widths instead of bit offsets.
 434         * ld-insn.c (parse_insn_format): Parse instruction fields
 435         specifying widths.
 436
 437         * misc.c (a2i): Allow binary numbers to be specified using the
 438         syntax 0bNNNN.
 439         * ld-insn.c: Allow such numbers to appear in the instruction
 440         format.
 441
 442         * table.c (table_entry_read): Make // a valid comment character.
 443         (table_entry_read): Skip lines containing a leading " - these may
 444         eventually be used in a disasembler.
