579 * igen.c (main): Correct usage. Missleading message about ucase
580 options dumping internal tables. -F now includes rather then
581 excludes instructions.
583 * misc.h, misc.c (a2i): Make 64bit.
585 * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
586 max to 64bits, expect trouble. Make the default 32 bits.
587 * gen-idecode.c (print_idecode_table): Change EXTRACTED*
588 et.al. macro's to use the insn_bit_size instead of assuming 32
590 * gen-icache.c (print_icache_extraction): Ditto.
591 * gen-idecode.c (idecode_switch_start): Ditto.
592 * gen-idecode.c (gen_idecode_c): Ditto
594 * igen.h (insn_specifying_widths), igen.c (main): New option -W.
595 Indicates that the instruction field of the table is specifying
596 bit widths instead of bit offsets.
597 * ld-insn.c (parse_insn_format): Parse instruction fields
600 * misc.c (a2i): Allow binary numbers to be specified using the
602 * ld-insn.c: Allow such numbers to appear in the instruction
605 * table.c (table_entry_read): Make // a valid comment character.
606 (table_entry_read): Skip lines containing a leading " - these may
607 eventually be used in a disasembler.
