1140         * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
1141         files, will at some stage need to move it into support.
1142
1143         * igen.h, igen.c (main): New option -e <engine> - generate a full
1144         simulation engine.  Previously this was the -d <idecode-file>
1145         option.
1146         * gen-engine.h, gen-engine.c: Copies of gen-idecode.*.  Will need
1147         to clean these up so that that call upon the updated gen-idecode
1148         code.
1149
1150         * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
1151         generating a decode table.

1154
1155         * igen.h, igen.c (main): New option -M - Control what is returned
1156         by semantic functions - -1/NIA vs CIA+N/NIA.  Add
1157         generate_semantic_returning_modified_nia_only to igen_code enum.
1158         * gen-semantics.c (print_semantic_body): As an alternative, make
1159         NIA == -1 instead of CIA+insn_size by default.
1160
1161         * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
1162         New option -P <prefix> - Prepend all generated functions with the
1163         specified prefix.
1164         (gen_idecode_c): Adjust.
1165         * gen-icache.c (print_icache_struct): Ditto.

1169
1170         * igen.c (main): Correct usage. Missleading message about ucase
1171         options dumping internal tables.  -F now includes rather then
1172         excludes instructions.
1173
1174         * misc.h, misc.c (a2i): Make 64bit.
1175
1176         * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
1177         max to 64bits, expect trouble.  Make the default 32 bits.
1178         * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1179         et.al. macro's to use the insn_bit_size instead of assuming 32
1180         bits.
1181         * gen-icache.c (print_icache_extraction): Ditto.
1182         * gen-idecode.c (idecode_switch_start): Ditto.
1183         * gen-idecode.c (gen_idecode_c): Ditto
1184
1185         * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1186         Indicates that the instruction field of the table is specifying
1187         bit widths instead of bit offsets.
1188         * ld-insn.c (parse_insn_format): Parse instruction fields
1189         specifying widths.
1190
1191         * misc.c (a2i): Allow binary numbers to be specified using the
1192         syntax 0bNNNN.
1193         * ld-insn.c: Allow such numbers to appear in the instruction
1194         format.
1195
1196         * table.c (table_entry_read): Make // a valid comment character.
1197         (table_entry_read): Skip lines containing a leading " - these may
1198         eventually be used in a disasembler.
