610 (print_icache_internal_function_definition): Update.
612 * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
613 files, will at some stage need to move it into support.
615 * igen.h, igen.c (main): New option -e <engine> - generate a full
616 simulation engine. Previously this was the -d <idecode-file>
618 * gen-engine.h, gen-engine.c: Copies of gen-idecode.*. Will need
619 to clean these up so that that call upon the updated gen-idecode
622 * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
623 generating a decode table.
625 * Makefile.in (igen): Add dependencies for new gen-engine.* files.
627 * igen.h, igen.c (main): New option -M - Control what is returned
628 by semantic functions - -1/NIA vs CIA+N/NIA. Add
629 generate_semantic_returning_modified_nia_only to igen_code enum.
630 * gen-semantics.c (print_semantic_body): As an alternative, make
631 NIA == -1 instead of CIA+insn_size by default.
633 * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
634 New option -P <prefix> - Prepend all generated functions with the
636 (gen_idecode_c): Adjust.

642 * igen.c (main): Correct usage. Missleading message about ucase
643 options dumping internal tables. -F now includes rather then
644 excludes instructions.
646 * misc.h, misc.c (a2i): Make 64bit.
648 * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
649 max to 64bits, expect trouble. Make the default 32 bits.
650 * gen-idecode.c (print_idecode_table): Change EXTRACTED*
651 et.al. macro's to use the insn_bit_size instead of assuming 32
653 * gen-icache.c (print_icache_extraction): Ditto.
654 * gen-idecode.c (idecode_switch_start): Ditto.
655 * gen-idecode.c (gen_idecode_c): Ditto
657 * igen.h (insn_specifying_widths), igen.c (main): New option -W.
658 Indicates that the instruction field of the table is specifying
659 bit widths instead of bit offsets.
660 * ld-insn.c (parse_insn_format): Parse instruction fields
663 * misc.c (a2i): Allow binary numbers to be specified using the
665 * ld-insn.c: Allow such numbers to appear in the instruction
668 * table.c (table_entry_read): Make // a valid comment character.
669 (table_entry_read): Skip lines containing a leading " - these may
670 eventually be used in a disasembler.
