1177
1178         * igen.h, igen.c (main): New option -e <engine> - generate a full
1179         simulation engine.  Previously this was the -d <idecode-file>

1204
1205         * igen.c (main): Correct usage. Missleading message about ucase
1206         options dumping internal tables.  -F now includes rather then

1213         * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1214         et.al. macro's to use the insn_bit_size instead of assuming 32
1215         bits.
1216         * gen-icache.c (print_icache_extraction): Ditto.
1217         * gen-idecode.c (idecode_switch_start): Ditto.

1219
1220         * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1221         Indicates that the instruction field of the table is specifying
1222         bit widths instead of bit offsets.
1223         * ld-insn.c (parse_insn_format): Parse instruction fields
1224         specifying widths.
1225
1226         * misc.c (a2i): Allow binary numbers to be specified using the
1227         syntax 0bNNNN.
1228         * ld-insn.c: Allow such numbers to appear in the instruction
1229         format.

1231         * table.c (table_entry_read): Make // a valid comment character.
1232         (table_entry_read): Skip lines containing a leading " - these may
1233         eventually be used in a disasembler.
