1127 (engine_switch_leaf): Ditto.
1128 * gen-support.c (print_support_function_name): Ditto.
1129 * gen-semantics.c (print_semantic_function_header): Update.
1131 * gen-icache.c (print_icache_function_header): Update.
1132 (print_icache_function): Update.
1133 (print_icache_internal_function_declaration): Update.
1134 (print_icache_internal_function_definition): Update.
1136 * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
1137 files, will at some stage need to move it into support.
1139 * igen.h, igen.c (main): New option -e <engine> - generate a full
1140 simulation engine. Previously this was the -d <idecode-file>
1142 * gen-engine.h, gen-engine.c: Copies of gen-idecode.*. Will need
1143 to clean these up so that that call upon the updated gen-idecode
1146 * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
1147 generating a decode table.
1149 * Makefile.in (igen): Add dependencies for new gen-engine.* files.
1151 * igen.h, igen.c (main): New option -M - Control what is returned
1152 by semantic functions - -1/NIA vs CIA+N/NIA. Add
1153 generate_semantic_returning_modified_nia_only to igen_code enum.
1154 * gen-semantics.c (print_semantic_body): As an alternative, make
1155 NIA == -1 instead of CIA+insn_size by default.
1157 * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
1158 New option -P <prefix> - Prepend all generated functions with the
1160 (gen_idecode_c): Adjust.

1166 * igen.c (main): Correct usage. Missleading message about ucase
1167 options dumping internal tables. -F now includes rather then
1168 excludes instructions.
1170 * misc.h, misc.c (a2i): Make 64bit.
1172 * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
1173 max to 64bits, expect trouble. Make the default 32 bits.
1174 * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1175 et.al. macro's to use the insn_bit_size instead of assuming 32
1177 * gen-icache.c (print_icache_extraction): Ditto.
1178 * gen-idecode.c (idecode_switch_start): Ditto.
1179 * gen-idecode.c (gen_idecode_c): Ditto
1181 * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1182 Indicates that the instruction field of the table is specifying
1183 bit widths instead of bit offsets.
1184 * ld-insn.c (parse_insn_format): Parse instruction fields
1187 * misc.c (a2i): Allow binary numbers to be specified using the
1189 * ld-insn.c: Allow such numbers to appear in the instruction
1192 * table.c (table_entry_read): Make // a valid comment character.
1193 (table_entry_read): Skip lines containing a leading " - these may
1194 eventually be used in a disasembler.
