1169
1170         * igen.h, igen.c (main): New option -e <engine> - generate a full
1171         simulation engine.  Previously this was the -d <idecode-file>
1172         option.
1173         * gen-engine.h, gen-engine.c: Copies of gen-idecode.*.  Will need

1196
1197         * igen.c (main): Correct usage. Missleading message about ucase
1198         options dumping internal tables.  -F now includes rather then

1204         max to 64bits, expect trouble.  Make the default 32 bits.
1205         * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1206         et.al. macro's to use the insn_bit_size instead of assuming 32
1207         bits.
1208         * gen-icache.c (print_icache_extraction): Ditto.
1209         * gen-idecode.c (idecode_switch_start): Ditto.

1211
1212         * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1213         Indicates that the instruction field of the table is specifying
1214         bit widths instead of bit offsets.
1215         * ld-insn.c (parse_insn_format): Parse instruction fields
1216         specifying widths.
1217
1218         * misc.c (a2i): Allow binary numbers to be specified using the
1219         syntax 0bNNNN.
1220         * ld-insn.c: Allow such numbers to appear in the instruction
1221         format.
1222
1223         * table.c (table_entry_read): Make // a valid comment character.
1224         (table_entry_read): Skip lines containing a leading " - these may
1225         eventually be used in a disasembler.
