994 files, will at some stage need to move it into support.
995
996 * igen.h, igen.c (main): New option -e <engine> - generate a full
997 simulation engine. Previously this was the -d <idecode-file>
998 option.
999 * gen-engine.h, gen-engine.c: Copies of gen-idecode.*. Will need
1000 to clean these up so that that call upon the updated gen-idecode
1001 code.
1002

1004 generating a decode table.

1006 * Makefile.in (igen): Add dependencies for new gen-engine.* files.
1007
1008 * igen.h, igen.c (main): New option -M - Control what is returned
1009 by semantic functions - -1/NIA vs CIA+N/NIA. Add
1010 generate_semantic_returning_modified_nia_only to igen_code enum.

1022
1023 * igen.c (main): Correct usage. Missleading message about ucase
1024 options dumping internal tables. -F now includes rather then
1025 excludes instructions.
1026
1027 * misc.h, misc.c (a2i): Make 64bit.
1028
1029 * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
1030 max to 64bits, expect trouble. Make the default 32 bits.
1031 * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1032 et.al. macro's to use the insn_bit_size instead of assuming 32
1033 bits.
1034 * gen-icache.c (print_icache_extraction): Ditto.
1035 * gen-idecode.c (idecode_switch_start): Ditto.
1036 * gen-idecode.c (gen_idecode_c): Ditto
1037
1038 * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1039 Indicates that the instruction field of the table is specifying
1040 bit widths instead of bit offsets.
1041 * ld-insn.c (parse_insn_format): Parse instruction fields
1042 specifying widths.
1043
1044 * misc.c (a2i): Allow binary numbers to be specified using the
1045 syntax 0bNNNN.
1046 * ld-insn.c: Allow such numbers to appear in the instruction
1047 format.
1048
1049 * table.c (table_entry_read): Make // a valid comment character.
1050 (table_entry_read): Skip lines containing a leading " - these may
1051 eventually be used in a disasembler.
