1104         (print_icache_internal_function_definition): Update.
1105
1106         * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
1107         files, will at some stage need to move it into support.
1108
1109         * igen.h, igen.c (main): New option -e <engine> - generate a full
1110         simulation engine.  Previously this was the -d <idecode-file>
1111         option.
1112         * gen-engine.h, gen-engine.c: Copies of gen-idecode.*.  Will need
1113         to clean these up so that that call upon the updated gen-idecode
1114         code.
1115
1116         * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
1117         generating a decode table.
1118
1119         * Makefile.in (igen): Add dependencies for new gen-engine.* files.
1120
1121         * igen.h, igen.c (main): New option -M - Control what is returned
1122         by semantic functions - -1/NIA vs CIA+N/NIA.  Add
1123         generate_semantic_returning_modified_nia_only to igen_code enum.
1124         * gen-semantics.c (print_semantic_body): As an alternative, make
1125         NIA == -1 instead of CIA+insn_size by default.
1126
1127         * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
1128         New option -P <prefix> - Prepend all generated functions with the
1129         specified prefix.
1130         (gen_idecode_c): Adjust.
1131         * gen-icache.c (print_icache_struct): Ditto.
1132         * gen-support.c (gen_support_c): Ditto.

1135
1136         * igen.c (main): Correct usage. Missleading message about ucase
1137         options dumping internal tables.  -F now includes rather then
1138         excludes instructions.
1139
1140         * misc.h, misc.c (a2i): Make 64bit.
1141
1142         * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
1143         max to 64bits, expect trouble.  Make the default 32 bits.
1144         * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1145         et.al. macro's to use the insn_bit_size instead of assuming 32
1146         bits.
1147         * gen-icache.c (print_icache_extraction): Ditto.
1148         * gen-idecode.c (idecode_switch_start): Ditto.
1149         * gen-idecode.c (gen_idecode_c): Ditto
1150
1151         * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1152         Indicates that the instruction field of the table is specifying
1153         bit widths instead of bit offsets.
1154         * ld-insn.c (parse_insn_format): Parse instruction fields
1155         specifying widths.
1156
1157         * misc.c (a2i): Allow binary numbers to be specified using the
1158         syntax 0bNNNN.
1159         * ld-insn.c: Allow such numbers to appear in the instruction
1160         format.
1161
1162         * table.c (table_entry_read): Make // a valid comment character.
1163         (table_entry_read): Skip lines containing a leading " - these may
1164         eventually be used in a disasembler.
