 743
 744         * igen.h, igen.c (main): New option -e <engine> - generate a full
 745         simulation engine.  Previously this was the -d <idecode-file>
 746         option.
 747         * gen-engine.h, gen-engine.c: Copies of gen-idecode.*.  Will need
 748         to clean these up so that that call upon the updated gen-idecode
 749         code.
 750
 751         * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
 752         generating a decode table.
 753
 754         * Makefile.in (igen): Add dependencies for new gen-engine.* files.
 755
 756         * igen.h, igen.c (main): New option -M - Control what is returned
 757         by semantic functions - -1/NIA vs CIA+N/NIA.  Add
 758         generate_semantic_returning_modified_nia_only to igen_code enum.
 759         * gen-semantics.c (print_semantic_body): As an alternative, make
 760         NIA == -1 instead of CIA+insn_size by default.
 761
 762         * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
 763         New option -P <prefix> - Prepend all generated functions with the
 764         specified prefix.
 765         (gen_idecode_c): Adjust.
 766         * gen-icache.c (print_icache_struct): Ditto.
 767         * gen-support.c (gen_support_c): Ditto.

 770
 771         * igen.c (main): Correct usage. Missleading message about ucase
 772         options dumping internal tables.  -F now includes rather then
 773         excludes instructions.
 774
 775         * misc.h, misc.c (a2i): Make 64bit.
 776
 777         * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
 778         max to 64bits, expect trouble.  Make the default 32 bits.
 779         * gen-idecode.c (print_idecode_table): Change EXTRACTED*
 780         et.al. macro's to use the insn_bit_size instead of assuming 32
 781         bits.
 782         * gen-icache.c (print_icache_extraction): Ditto.
 783         * gen-idecode.c (idecode_switch_start): Ditto.
 784         * gen-idecode.c (gen_idecode_c): Ditto
 785
 786         * igen.h (insn_specifying_widths), igen.c (main): New option -W.
 787         Indicates that the instruction field of the table is specifying
 788         bit widths instead of bit offsets.
 789         * ld-insn.c (parse_insn_format): Parse instruction fields
 790         specifying widths.
 791
 792         * misc.c (a2i): Allow binary numbers to be specified using the
 793         syntax 0bNNNN.
 794         * ld-insn.c: Allow such numbers to appear in the instruction
 795         format.
 796
 797         * table.c (table_entry_read): Make // a valid comment character.
 798         (table_entry_read): Skip lines containing a leading " - these may
 799         eventually be used in a disasembler.
