* genpreds.c: Add capability to generate predicate bodies as well as function prototypes. Write function prototypes for the generic predicates too. (process_define_predicate, write_tm_preds_h, write_insn_preds_c) (write_predicate_subfunction, mark_mode_tests, add_mode_tests) (write_match_code, write_predicate_expr, write_one_predicate_function) (parse_option): New functions. (output_predicate_decls): Delete. (main): Read the machine description, process DEFINE_PREDICATE or DEFINE_SPECIAL_PREDICATE patterns, write tm-preds.h or insn-preds.c as appropriate. * genrecog.c (struct decision_test): Replace index with struct pred_data pointer. (next_index): Remove, unused. (pred_table, preds, special_mode_pred_table): Delete. (compute_predicate_codes, process_define_predicate): New functions. (validate_pattern, add_to_sequence, write_switch): Update for new data structures. (main): Handle DEFINE_PREDICATE and DEFINE_SPECIAL_PREDICATE. Check both error_count and have_error. * gensupport.c (in_fname, first_predicate): New globals. (define_pred_queue, define_pred_tail): New RTL-pattern queue. (predicate_table, last_predicate, old_pred_table) (old_special_pred_table): New statics. (hash_struct_pred_data, eq_struct_pred_data, lookup_predicate) (add_predicate, init_predicate_table): New functions. (process_rtx): Handle DEFINE_PREDICATE and DEFINE_SPECIAL_PREDICATE. (init_md_reader_args_cb): Use the global in_fname. No need to zero it or max_include_len. Call init_predicate_table. (read_rtx): Run the predicate queue after the attribute queue but before all the others. * gensupport.h (in_fname, struct pred_data, first_predicate) (lookup_predicate, add_predicate, FOR_ALL_PREDICATES): Declare. * rtl.def (MATCH_CODE, MATCH_TEST, DEFINE_PREDICATE) (DEFINE_SPECIAL_PREDICATE): New RTL codes. * dummy-conditions.c: Don't include bconfig.h, system.h, coretypes.h, tm.h, or system.h. Do include stddef.h. Duplicate declaration of struct c_test from gensupport.h. * Makefile.in (OBJS-common): Add insn-preds.o. (STAGESTUFF, .PRECIOUS): Add insn-preds.c. (insn-preds.c, insn-preds.o): New rules. (s-preds): Also generate insn-preds.c. (dummy-conditions.o, genpreds$(build_exeext), genpreds.o): Update dependencies. (print-rtl.o, print-rtl1.o): Correct dependencies. * recog.h: Delete prototypes of predicate functions. * doc/md.texi (Predicates): New section with complete documentation of operand/operator predicates. Remove some incomplete documentation of predicates from other places. * doc/tm.texi (Misc): Move SPECIAL_MODE_PREDICATES next to PREDICATE_CODES; indicate that both are deprecated in favor of define_predicate/define_special_predicate. * config/ia64/ia64.c: All predicate function definitions moved to ia64.md, except (small_addr_symbolic_operand, tls_symbolic_operand): Delete. (ia64_expand_load_address, ia64_expand_move): Check SYMBOL_REF_TLS_MODEL directly, don't use tls_symbolic_operand. * config/ia64/ia64.md: All predicates now defined here. (symbolic_operand): Is now a special predicate. * config/ia64/ia64.h: Declare ia64_section_threshold. (PREDICATE_CODES): Delete. From-SVN: r85855
