1117 generating a decode table.
1119 * Makefile.in (igen): Add dependencies for new gen-engine.* files.
1121 * igen.h, igen.c (main): New option -M - Control what is returned
1122 by semantic functions - -1/NIA vs CIA+N/NIA. Add
1123 generate_semantic_returning_modified_nia_only to igen_code enum.
1124 * gen-semantics.c (print_semantic_body): As an alternative, make
1125 NIA == -1 instead of CIA+insn_size by default.
1127 * igen.h, igen.c (main, global_name_prefix, global_uname_prefix):
1128 New option -P <prefix> - Prepend all generated functions with the
1130 (gen_idecode_c): Adjust.
1131 * gen-icache.c (print_icache_struct): Ditto.
1132 * gen-support.c (gen_support_c): Ditto.

1136 * igen.c (main): Correct usage. Missleading message about ucase
1137 options dumping internal tables. -F now includes rather then
1138 excludes instructions.
1140 * misc.h, misc.c (a2i): Make 64bit.
1142 * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase
1143 max to 64bits, expect trouble. Make the default 32 bits.
1144 * gen-idecode.c (print_idecode_table): Change EXTRACTED*
1145 et.al. macro's to use the insn_bit_size instead of assuming 32
1147 * gen-icache.c (print_icache_extraction): Ditto.
1148 * gen-idecode.c (idecode_switch_start): Ditto.
1149 * gen-idecode.c (gen_idecode_c): Ditto
1151 * igen.h (insn_specifying_widths), igen.c (main): New option -W.
1152 Indicates that the instruction field of the table is specifying
1153 bit widths instead of bit offsets.
1154 * ld-insn.c (parse_insn_format): Parse instruction fields
1157 * misc.c (a2i): Allow binary numbers to be specified using the
1159 * ld-insn.c: Allow such numbers to appear in the instruction
1162 * table.c (table_entry_read): Make // a valid comment character.
1163 (table_entry_read): Skip lines containing a leading " - these may
1164 eventually be used in a disasembler.
