1123 * igen.c (main): Correct usage. Missleading message about ucase
1124 options dumping internal tables. -F now includes rather then
1125 excludes instructions.
1127 * misc.h, misc.c (a2i): Make 64bit.
1129 * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
1130 max to 64bits, expect trouble. Make the default 32 bits.
1131 * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1132 et.al. macro's to use the insn_bit_size instead of assuming 32
1134 * gen-icache.c (print_icache_extraction): Ditto.
1135 * gen-idecode.c (idecode_switch_start): Ditto.
1136 * gen-idecode.c (gen_idecode_c): Ditto
1138 * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1139 Indicates that the instruction field of the table is specifying
1140 bit widths instead of bit offsets.
1141 * ld-insn.c (parse_insn_format): Parse instruction fields
1144 * misc.c (a2i): Allow binary numbers to be specified using the
1146 * ld-insn.c: Allow such numbers to appear in the instruction
1149 * table.c (table_entry_read): Make // a valid comment character.
1150 (table_entry_read): Skip lines containing a leading " - these may
1151 eventually be used in a disasembler.
