 761
 762         * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
 763         files, will at some stage need to move it into support.
 764
 765         * igen.h, igen.c (main): New option -e <engine> - generate a full
 766         simulation engine.  Previously this was the -d <idecode-file>
 767         option.
 768         * gen-engine.h, gen-engine.c: Copies of gen-idecode.*.  Will need
 769         to clean these up so that that call upon the updated gen-idecode
 770         code.
 771
 772         * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
 773         generating a decode table.
 774
 775         * Makefile.in (igen): Add dependencies for new gen-engine.* files.
 776
 777         * igen.h, igen.c (main): New option -M - Control what is returned
 778         by semantic functions - -1/NIA vs CIA+N/NIA.  Add
 779         generate_semantic_returning_modified_nia_only to igen_code enum.
 780         * gen-semantics.c (print_semantic_body): As an alternative, make
 781         NIA == -1 instead of CIA+insn_size by default.
 782
 783         * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
 784         New option -P <prefix> - Prepend all generated functions with the
 785         specified prefix.
 786         (gen_idecode_c): Adjust.
 787         * gen-icache.c (print_icache_struct): Ditto.

 791
 792         * igen.c (main): Correct usage. Missleading message about ucase
 793         options dumping internal tables.  -F now includes rather then
 794         excludes instructions.
 795
 796         * misc.h, misc.c (a2i): Make 64bit.
 797
 798         * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
 799         max to 64bits, expect trouble.  Make the default 32 bits.
 800         * gen-idecode.c (print_idecode_table): Change EXTRACTED*
 801         et.al. macro's to use the insn_bit_size instead of assuming 32
 802         bits.
 803         * gen-icache.c (print_icache_extraction): Ditto.
 804         * gen-idecode.c (idecode_switch_start): Ditto.
 805         * gen-idecode.c (gen_idecode_c): Ditto
 806
 807         * igen.h (insn_specifying_widths), igen.c (main): New option -W.
 808         Indicates that the instruction field of the table is specifying
 809         bit widths instead of bit offsets.
 810         * ld-insn.c (parse_insn_format): Parse instruction fields
 811         specifying widths.
 812
 813         * misc.c (a2i): Allow binary numbers to be specified using the
 814         syntax 0bNNNN.
 815         * ld-insn.c: Allow such numbers to appear in the instruction
 816         format.
 817
 818         * table.c (table_entry_read): Make // a valid comment character.
 819         (table_entry_read): Skip lines containing a leading " - these may
 820         eventually be used in a disasembler.
