1106         Update.
1107         * gen-icache.c (print_icache_function_header): Update.
1108         (print_icache_function): Update.
1109         (print_icache_internal_function_declaration): Update.
1110         (print_icache_internal_function_definition): Update.
1111
1112         * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
1113         files, will at some stage need to move it into support.
1114
1115         * igen.h, igen.c (main): New option -e <engine> - generate a full
1116         simulation engine.  Previously this was the -d <idecode-file>
1117         option.
1118         * gen-engine.h, gen-engine.c: Copies of gen-idecode.*.  Will need
1119         to clean these up so that that call upon the updated gen-idecode
1120         code.
1121
1122         * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
1123         generating a decode table.
1124
1125         * Makefile.in (igen): Add dependencies for new gen-engine.* files.
1126
1127         * igen.h, igen.c (main): New option -M - Control what is returned
1128         by semantic functions - -1/NIA vs CIA+N/NIA.  Add
1129         generate_semantic_returning_modified_nia_only to igen_code enum.
1130         * gen-semantics.c (print_semantic_body): As an alternative, make
1131         NIA == -1 instead of CIA+insn_size by default.
1132
1133         * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
1134         New option -P <prefix> - Prepend all generated functions with the
1135         specified prefix.
1136         (gen_idecode_c): Adjust.
1137         * gen-icache.c (print_icache_struct): Ditto.
1138         * gen-support.c (gen_support_c): Ditto.

1141
1142         * igen.c (main): Correct usage. Missleading message about ucase
1143         options dumping internal tables.  -F now includes rather then
1144         excludes instructions.
1145
1146         * misc.h, misc.c (a2i): Make 64bit.
1147
1148         * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
1149         max to 64bits, expect trouble.  Make the default 32 bits.
1150         * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1151         et.al. macro's to use the insn_bit_size instead of assuming 32
1152         bits.
1153         * gen-icache.c (print_icache_extraction): Ditto.
1154         * gen-idecode.c (idecode_switch_start): Ditto.
1155         * gen-idecode.c (gen_idecode_c): Ditto
1156
1157         * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1158         Indicates that the instruction field of the table is specifying
1159         bit widths instead of bit offsets.
1160         * ld-insn.c (parse_insn_format): Parse instruction fields
1161         specifying widths.
1162
1163         * misc.c (a2i): Allow binary numbers to be specified using the
1164         syntax 0bNNNN.
1165         * ld-insn.c: Allow such numbers to appear in the instruction
1166         format.
1167
1168         * table.c (table_entry_read): Make // a valid comment character.
1169         (table_entry_read): Skip lines containing a leading " - these may
1170         eventually be used in a disasembler.
