660 files, will at some stage need to move it into support.
662 * igen.h, igen.c (main): New option -e <engine> - generate a full
663 simulation engine. Previously this was the -d <idecode-file>
665 * gen-engine.h, gen-engine.c: Copies of gen-idecode.*. Will need
666 to clean these up so that that call upon the updated gen-idecode
669 * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to

712 * ld-insn.c: Allow such numbers to appear in the instruction
715 * table.c (table_entry_read): Make // a valid comment character.
716 (table_entry_read): Skip lines containing a leading " - these may
717 eventually be used in a disasembler.
