1108         * gen-support.c (print_support_function_name): Ditto.
1109         * gen-semantics.c (print_semantic_function_header): Update.
1110         Update.
1111         * gen-icache.c (print_icache_function_header): Update.
1112         (print_icache_function): Update.
1113         (print_icache_internal_function_declaration): Update.
1114         (print_icache_internal_function_definition): Update.
1115
1116         * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
1117         files, will at some stage need to move it into support.
1118
1119         * igen.h, igen.c (main): New option -e <engine> - generate a full
1120         simulation engine.  Previously this was the -d <idecode-file>
1121         option.
1122         * gen-engine.h, gen-engine.c: Copies of gen-idecode.*.  Will need
1123         to clean these up so that that call upon the updated gen-idecode
1124         code.
1125
1126         * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
1127         generating a decode table.
1128
1129         * Makefile.in (igen): Add dependencies for new gen-engine.* files.
1130
1131         * igen.h, igen.c (main): New option -M - Control what is returned
1132         by semantic functions - -1/NIA vs CIA+N/NIA.  Add
1133         generate_semantic_returning_modified_nia_only to igen_code enum.
1134         * gen-semantics.c (print_semantic_body): As an alternative, make
1135         NIA == -1 instead of CIA+insn_size by default.
1136
1137         * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
1138         New option -P <prefix> - Prepend all generated functions with the
1139         specified prefix.
1140         (gen_idecode_c): Adjust.
1141         * gen-icache.c (print_icache_struct): Ditto.
1142         * gen-support.c (gen_support_c): Ditto.

1145
1146         * igen.c (main): Correct usage. Missleading message about ucase
1147         options dumping internal tables.  -F now includes rather then
1148         excludes instructions.
1149
1150         * misc.h, misc.c (a2i): Make 64bit.
1151
1152         * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
1153         max to 64bits, expect trouble.  Make the default 32 bits.
1154         * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1155         et.al. macro's to use the insn_bit_size instead of assuming 32
1156         bits.
1157         * gen-icache.c (print_icache_extraction): Ditto.
1158         * gen-idecode.c (idecode_switch_start): Ditto.
1159         * gen-idecode.c (gen_idecode_c): Ditto
1160
1161         * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1162         Indicates that the instruction field of the table is specifying
1163         bit widths instead of bit offsets.
1164         * ld-insn.c (parse_insn_format): Parse instruction fields
1165         specifying widths.
1166
1167         * misc.c (a2i): Allow binary numbers to be specified using the
1168         syntax 0bNNNN.
1169         * ld-insn.c: Allow such numbers to appear in the instruction
1170         format.
1171
1172         * table.c (table_entry_read): Make // a valid comment character.
1173         (table_entry_read): Skip lines containing a leading " - these may
1174         eventually be used in a disasembler.
