961 * igen.c (main): Correct usage. Missleading message about ucase
962 options dumping internal tables. -F now includes rather then
963 excludes instructions.
964
965 * misc.h, misc.c (a2i): Make 64bit.
966
967 * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
968 max to 64bits, expect trouble. Make the default 32 bits.
969 * gen-idecode.c (print_idecode_table): Change EXTRACTED*
970 et.al. macro's to use the insn_bit_size instead of assuming 32
971 bits.
972 * gen-icache.c (print_icache_extraction): Ditto.
973 * gen-idecode.c (idecode_switch_start): Ditto.
974 * gen-idecode.c (gen_idecode_c): Ditto
975
976 * igen.h (insn_specifying_widths), igen.c (main): New option -W.
977 Indicates that the instruction field of the table is specifying
978 bit widths instead of bit offsets.
979 * ld-insn.c (parse_insn_format): Parse instruction fields
980 specifying widths.
981
982 * misc.c (a2i): Allow binary numbers to be specified using the
983 syntax 0bNNNN.
984 * ld-insn.c: Allow such numbers to appear in the instruction
985 format.
986
987 * table.c (table_entry_read): Make // a valid comment character.
988 (table_entry_read): Skip lines containing a leading " - these may
989 eventually be used in a disasembler.
