1127
1128         * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h
1129         files, will at some stage need to move it into support.
1130
1131         * igen.h, igen.c (main): New option -e <engine> - generate a full
1132         simulation engine.  Previously this was the -d <idecode-file>
1133         option.
1134         * gen-engine.h, gen-engine.c: Copies of gen-idecode.*.  Will need
1135         to clean these up so that that call upon the updated gen-idecode
1136         code.
1137
1138         * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to
1139         generating a decode table.
1140
1141         * Makefile.in (igen): Add dependencies for new gen-engine.* files.
1142
1143         * igen.h, igen.c (main): New option -M - Control what is returned
1144         by semantic functions - -1/NIA vs CIA+N/NIA.  Add
1145         generate_semantic_returning_modified_nia_only to igen_code enum.
1146         * gen-semantics.c (print_semantic_body): As an alternative, make
1147         NIA == -1 instead of CIA+insn_size by default.
1148
1149         * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
1150         New option -P <prefix> - Prepend all generated functions with the
1151         specified prefix.
1152         (gen_idecode_c): Adjust.
1153         * gen-icache.c (print_icache_struct): Ditto.

1157
1158         * igen.c (main): Correct usage. Missleading message about ucase
1159         options dumping internal tables.  -F now includes rather then
1160         excludes instructions.
1161
1162         * misc.h, misc.c (a2i): Make 64bit.
1163
1164         * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
1165         max to 64bits, expect trouble.  Make the default 32 bits.
1166         * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1167         et.al. macro's to use the insn_bit_size instead of assuming 32
1168         bits.
1169         * gen-icache.c (print_icache_extraction): Ditto.
1170         * gen-idecode.c (idecode_switch_start): Ditto.
1171         * gen-idecode.c (gen_idecode_c): Ditto
1172
1173         * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1174         Indicates that the instruction field of the table is specifying
1175         bit widths instead of bit offsets.
1176         * ld-insn.c (parse_insn_format): Parse instruction fields
1177         specifying widths.
1178
1179         * misc.c (a2i): Allow binary numbers to be specified using the
1180         syntax 0bNNNN.
1181         * ld-insn.c: Allow such numbers to appear in the instruction
1182         format.
1183
1184         * table.c (table_entry_read): Make // a valid comment character.
1185         (table_entry_read): Skip lines containing a leading " - these may
1186         eventually be used in a disasembler.
