1149 (print_icache_internal_function_definition): Update.
1151 * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
1152 files, will at some stage need to move it into support.
1154 * igen.h, igen.c (main): New option -e <engine> - generate a full
1155 simulation engine. Previously this was the -d <idecode-file>
1157 * gen-engine.h, gen-engine.c: Copies of gen-idecode.*. Will need
1158 to clean these up so that that call upon the updated gen-idecode
1161 * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
1162 generating a decode table.
1164 * Makefile.in (igen): Add dependencies for new gen-engine.* files.
1166 * igen.h, igen.c (main): New option -M - Control what is returned
1167 by semantic functions - -1/NIA vs CIA+N/NIA. Add
1168 generate_semantic_returning_modified_nia_only to igen_code enum.
1169 * gen-semantics.c (print_semantic_body): As an alternative, make
1170 NIA == -1 instead of CIA+insn_size by default.
1172 * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
1173 New option -P <prefix> - Prepend all generated functions with the
1175 (gen_idecode_c): Adjust.

1181 * igen.c (main): Correct usage. Missleading message about ucase
1182 options dumping internal tables. -F now includes rather then
1183 excludes instructions.
1185 * misc.h, misc.c (a2i): Make 64bit.
1187 * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
1188 max to 64bits, expect trouble. Make the default 32 bits.
1189 * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1190 et.al. macro's to use the insn_bit_size instead of assuming 32
1192 * gen-icache.c (print_icache_extraction): Ditto.
1193 * gen-idecode.c (idecode_switch_start): Ditto.
1194 * gen-idecode.c (gen_idecode_c): Ditto
1196 * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1197 Indicates that the instruction field of the table is specifying
1198 bit widths instead of bit offsets.
1199 * ld-insn.c (parse_insn_format): Parse instruction fields
1202 * misc.c (a2i): Allow binary numbers to be specified using the
1204 * ld-insn.c: Allow such numbers to appear in the instruction
1207 * table.c (table_entry_read): Make // a valid comment character.
1208 (table_entry_read): Skip lines containing a leading " - these may
1209 eventually be used in a disasembler.
