 793         files, will at some stage need to move it into support.
 794
 795         * igen.h, igen.c (main): New option -e <engine> - generate a full
 796         simulation engine.  Previously this was the -d <idecode-file>
 797         option.
 798         * gen-engine.h, gen-engine.c: Copies of gen-idecode.*.  Will need

 808         by semantic functions - -1/NIA vs CIA+N/NIA.  Add
 809         generate_semantic_returning_modified_nia_only to igen_code enum.

 814         New option -P <prefix> - Prepend all generated functions with the

 821
 822         * igen.c (main): Correct usage. Missleading message about ucase
 823         options dumping internal tables.  -F now includes rather then
 824         excludes instructions.
 825
 826         * misc.h, misc.c (a2i): Make 64bit.

 829         max to 64bits, expect trouble.  Make the default 32 bits.
 830         * gen-idecode.c (print_idecode_table): Change EXTRACTED*
 831         et.al. macro's to use the insn_bit_size instead of assuming 32
 832         bits.
 833         * gen-icache.c (print_icache_extraction): Ditto.
 834         * gen-idecode.c (idecode_switch_start): Ditto.
 835         * gen-idecode.c (gen_idecode_c): Ditto
 836
 837         * igen.h (insn_specifying_widths), igen.c (main): New option -W.
 838         Indicates that the instruction field of the table is specifying
 839         bit widths instead of bit offsets.
 840         * ld-insn.c (parse_insn_format): Parse instruction fields
 841         specifying widths.
 842
 843         * misc.c (a2i): Allow binary numbers to be specified using the
 844         syntax 0bNNNN.
 845         * ld-insn.c: Allow such numbers to appear in the instruction
 846         format.
 847
 848         * table.c (table_entry_read): Make // a valid comment character.
 849         (table_entry_read): Skip lines containing a leading " - these may
 850         eventually be used in a disasembler.
