1167 * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
1168 files, will at some stage need to move it into support.
1170 * igen.h, igen.c (main): New option -e <engine> - generate a full
1171 simulation engine. Previously this was the -d <idecode-file>
1173 * gen-engine.h, gen-engine.c: Copies of gen-idecode.*. Will need
1174 to clean these up so that that call upon the updated gen-idecode
1177 * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
1178 generating a decode table.
1180 * Makefile.in (igen): Add dependencies for new gen-engine.* files.

1197 * igen.c (main): Correct usage. Missleading message about ucase
1198 options dumping internal tables. -F now includes rather then
1199 excludes instructions.
1201 * misc.h, misc.c (a2i): Make 64bit.
1203 * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
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
1208 * gen-icache.c (print_icache_extraction): Ditto.
1209 * gen-idecode.c (idecode_switch_start): Ditto.
1210 * gen-idecode.c (gen_idecode_c): Ditto

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
1218 * misc.c (a2i): Allow binary numbers to be specified using the
1220 * ld-insn.c: Allow such numbers to appear in the instruction
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.
