1182
1183         * igen.h, igen.c (main): New option -e <engine> - generate a full
1184         simulation engine.  Previously this was the -d <idecode-file>

1209
1210         * igen.c (main): Correct usage. Missleading message about ucase
1211         options dumping internal tables.  -F now includes rather then

1217         max to 64bits, expect trouble.  Make the default 32 bits.
1218         * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1219         et.al. macro's to use the insn_bit_size instead of assuming 32
1220         bits.
1221         * gen-icache.c (print_icache_extraction): Ditto.
1222         * gen-idecode.c (idecode_switch_start): Ditto.

1224
1225         * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1226         Indicates that the instruction field of the table is specifying
1227         bit widths instead of bit offsets.
1228         * ld-insn.c (parse_insn_format): Parse instruction fields
1229         specifying widths.
1230
1231         * misc.c (a2i): Allow binary numbers to be specified using the
1232         syntax 0bNNNN.
1233         * ld-insn.c: Allow such numbers to appear in the instruction
1234         format.
1235
1236         * table.c (table_entry_read): Make // a valid comment character.
1237         (table_entry_read): Skip lines containing a leading " - these may
1238         eventually be used in a disasembler.
