1124 * gen-support.c (print_support_function_name): Ditto.
1125 * gen-semantics.c (print_semantic_function_header): Update.
1127 * gen-icache.c (print_icache_function_header): Update.
1128 (print_icache_function): Update.
1129 (print_icache_internal_function_declaration): Update.
1130 (print_icache_internal_function_definition): Update.
1132 * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
1133 files, will at some stage need to move it into support.
1135 * igen.h, igen.c (main): New option -e <engine> - generate a full
1136 simulation engine. Previously this was the -d <idecode-file>
1138 * gen-engine.h, gen-engine.c: Copies of gen-idecode.*. Will need
1139 to clean these up so that that call upon the updated gen-idecode
1142 * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
1143 generating a decode table.
1145 * Makefile.in (igen): Add dependencies for new gen-engine.* files.
1147 * igen.h, igen.c (main): New option -M - Control what is returned
1148 by semantic functions - -1/NIA vs CIA+N/NIA. Add
1149 generate_semantic_returning_modified_nia_only to igen_code enum.
1150 * gen-semantics.c (print_semantic_body): As an alternative, make
1151 NIA == -1 instead of CIA+insn_size by default.
1153 * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
1154 New option -P <prefix> - Prepend all generated functions with the
1156 (gen_idecode_c): Adjust.
1157 * gen-icache.c (print_icache_struct): Ditto.
1158 * gen-support.c (gen_support_c): Ditto.

1162 * igen.c (main): Correct usage. Missleading message about ucase
1163 options dumping internal tables. -F now includes rather then
1164 excludes instructions.
1166 * misc.h, misc.c (a2i): Make 64bit.
1168 * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
1169 max to 64bits, expect trouble. Make the default 32 bits.
1170 * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1171 et.al. macro's to use the insn_bit_size instead of assuming 32
1173 * gen-icache.c (print_icache_extraction): Ditto.
1174 * gen-idecode.c (idecode_switch_start): Ditto.
1175 * gen-idecode.c (gen_idecode_c): Ditto
1177 * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1178 Indicates that the instruction field of the table is specifying
1179 bit widths instead of bit offsets.
1180 * ld-insn.c (parse_insn_format): Parse instruction fields
1183 * misc.c (a2i): Allow binary numbers to be specified using the
1185 * ld-insn.c: Allow such numbers to appear in the instruction
1188 * table.c (table_entry_read): Make // a valid comment character.
1189 (table_entry_read): Skip lines containing a leading " - these may
1190 eventually be used in a disasembler.
