(address_word): New. Used by igen. * lf.c (lf_print_function_type_function): New, pass a function to print out the type instead of a constant string. * igen.h, igen.c (print_semantic_function_formal, SEMANTIC_FUNCTION_FORMAL): Relace macro with function. (print_semantic_function_actual, SEMANTIC_FUNCTION_ACTUAL): Ditto. (print_semantic_function_type, SEMANTIC_FUNCTION_TYPE): Ditto. (print_icache_function_type, ICACHE_FUNCTION_TYPE): Ditto. (print_icache_function_formal, ICACHE_FUNCTION_FORMAL): Ditto. (print_icache_function_actual, ICACHE_FUNCTION_ACTUAL): Ditto. * gen-idecode.c (print_idecode_table): Update. (idecode_switch_leaf): Update. (print_idecode_switch_function_header): Ditto. (print_idecode_floating_point_unavailable): Ditto. (print_idecode_issue_function_header): Ditto. * igen.c (gen_icache_h): Ditto. * gen-engine.c (print_engine_table): Ditto. (engine_switch_leaf): Ditto. * gen-support.c (print_support_function_name): Ditto. * gen-semantics.c (print_semantic_function_header): Update. Update. * gen-icache.c (print_icache_function_header): Update. (print_icache_function): Update. (print_icache_internal_function_declaration): Update. (print_icache_internal_function_definition): Update. * gen-idecode.c (gen_idecode_h): Drop including of idecode_*.h files, will at some stage need to move it into support. * igen.h, igen.c (main): New option -e - generate a full simulation engine. Previously this was the -d option. * gen-engine.h, gen-engine.c: Copies of gen-idecode.*. Will need to clean these up so that that call upon the updated gen-idecode code. * gen-idecode.h, gen-idecode.c: Prune out any code not relevant to generating a decode table. * Makefile.in (igen): Add dependencies for new gen-engine.* files. * igen.h, igen.c (main): New option -M - Control what is returned by semantic functions - -1/NIA vs CIA+N/NIA. Add generate_semantic_returning_modified_nia_only to igen_code enum. * gen-semantics.c (print_semantic_body): As an alternative, make NIA == -1 instead of CIA+insn_size by default. * igen.h, igen.c (main, global_name_prefix, global_uname_prefix): New option -P - Prepend all generated functions with the specified prefix. (gen_idecode_c): Adjust. * gen-icache.c (print_icache_struct): Ditto. * gen-support.c (gen_support_c): Ditto. Sun Feb 16 15:23:15 1997 Andrew Cagney * igen.c (main): Correct usage. Missleading message about ucase options dumping internal tables. -F now includes rather then excludes instructions. * misc.h, misc.c (a2i): Make 64bit. * ld-insn.h (max_insn_bit_size, default_insn_bit_size): Increase max to 64bits, expect trouble. Make the default 32 bits. * gen-idecode.c (print_idecode_table): Change EXTRACTED* et.al. macro's to use the insn_bit_size instead of assuming 32 bits. * gen-icache.c (print_icache_extraction): Ditto. * gen-idecode.c (idecode_switch_start): Ditto. * gen-idecode.c (gen_idecode_c): Ditto * igen.h (insn_specifying_widths), igen.c (main): New option -W. Indicates that the instruction field of the table is specifying bit widths instead of bit offsets. * ld-insn.c (parse_insn_format): Parse instruction fields specifying widths. * misc.c (a2i): Allow binary numbers to be specified using the syntax 0bNNNN. * ld-insn.c: Allow such numbers to appear in the instruction format. * table.c (table_entry_read): Make // a valid comment character. (table_entry_read): Skip lines containing a leading " - these may eventually be used in a disasembler.
