576 * gen-engine.h, gen-engine.c: Copies of gen-idecode.*. Will need
577 to clean these up so that that call upon the updated gen-idecode
580 * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
581 generating a decode table.
583 * Makefile.in (igen): Add dependencies for new gen-engine.* files.
585 * igen.h, igen.c (main): New option -M - Control what is returned
586 by semantic functions - -1/NIA vs CIA+N/NIA. Add
587 generate_semantic_returning_modified_nia_only to igen_code enum.
588 * gen-semantics.c (print_semantic_body): As an alternative, make
589 NIA == -1 instead of CIA+insn_size by default.
591 * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
592 New option -P <prefix> - Prepend all generated functions with the
594 (gen_idecode_c): Adjust.
595 * gen-icache.c (print_icache_struct): Ditto.
596 * gen-support.c (gen_support_c): Ditto.

600 * igen.c (main): Correct usage. Missleading message about ucase
601 options dumping internal tables. -F now includes rather then
602 excludes instructions.
604 * misc.h, misc.c (a2i): Make 64bit.
606 * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
607 max to 64bits, expect trouble. Make the default 32 bits.
608 * gen-idecode.c (print_idecode_table): Change EXTRACTED*
609 et.al. macro's to use the insn_bit_size instead of assuming 32
611 * gen-icache.c (print_icache_extraction): Ditto.
612 * gen-idecode.c (idecode_switch_start): Ditto.
613 * gen-idecode.c (gen_idecode_c): Ditto
615 * igen.h (insn_specifying_widths), igen.c (main): New option -W.
616 Indicates that the instruction field of the table is specifying
617 bit widths instead of bit offsets.
618 * ld-insn.c (parse_insn_format): Parse instruction fields
621 * misc.c (a2i): Allow binary numbers to be specified using the
623 * ld-insn.c: Allow such numbers to appear in the instruction
626 * table.c (table_entry_read): Make // a valid comment character.
627 (table_entry_read): Skip lines containing a leading " - these may
628 eventually be used in a disasembler.

641 renaming from filter_filename.[hc]
