587 (idecode_switch_leaf): Update.
588 (print_idecode_switch_function_header): Ditto.
589 (print_idecode_floating_point_unavailable): Ditto.
590 (print_idecode_issue_function_header): Ditto.
591 * igen.c (gen_icache_h): Ditto.
592 * gen-engine.c (print_engine_table): Ditto.
593 (engine_switch_leaf): Ditto.
594 * gen-support.c (print_support_function_name): Ditto.
595 * gen-semantics.c (print_semantic_function_header): Update.
597 * gen-icache.c (print_icache_function_header): Update.
598 (print_icache_function): Update.
599 (print_icache_internal_function_declaration): Update.
600 (print_icache_internal_function_definition): Update.
602 * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
603 files, will at some stage need to move it into support.
605 * igen.h, igen.c (main): New option -e <engine> - generate a full
606 simulation engine. Previously this was the -d <idecode-file>
608 * gen-engine.h, gen-engine.c: Copies of gen-idecode.*. Will need
609 to clean these up so that that call upon the updated gen-idecode
612 * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
613 generating a decode table.
615 * Makefile.in (igen): Add dependencies for new gen-engine.* files.
617 * igen.h, igen.c (main): New option -M - Control what is returned
618 by semantic functions - -1/NIA vs CIA+N/NIA. Add
619 generate_semantic_returning_modified_nia_only to igen_code enum.
620 * gen-semantics.c (print_semantic_body): As an alternative, make
621 NIA == -1 instead of CIA+insn_size by default.
623 * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
624 New option -P <prefix> - Prepend all generated functions with the
626 (gen_idecode_c): Adjust.
627 * gen-icache.c (print_icache_struct): Ditto.
628 * gen-support.c (gen_support_c): Ditto.

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