r110123@banpei: zack | 2006-01-22 14:44:34 -0800 * genconditions.c (condition_table, add_condition): Delete. (write_conditions): Don't emit n_insn_conditions nor insn_elision_unavailable. Issue the gcc version #ifdef here, inside the table, with no #else clause ... (write_header): ...not here. (write_writer): New function. (main): Don't initialize condition_table. Use add_c_test. Call write_writer. * gensupport.c (init_md_reader_args_cb): Handle multiple input files on the command line. (maybe_eval_c_test): Don't check insn_elision_unavailable. Return -1 if there is no entry in the table, don't abort. (add_c_test, traverse_c_tests): New functions. * gensupport.h (insn_elision_unavailable, insn_conditions) (n_insn_conditions): Delete declarations. (add_c_test, traverse_c_tests): Declare. * read-rtl.c: Include gensupport.h. (read_conditions): New function. (read_rtx): If read_rtx_1 returns 0, treat as EOF. (read_rtx_1): If we get EOF when we were looking for an initial open paren, return 0. Call read_conditions when appropriate. * Makefile.in: Kill BUILD_EARLY_SUPPORT and all references to dummy-conditions.o. Eliminate references to insn-conditions.o, or change them to build/gencondmd.o, as appropriate. Remove insn-constants.h from $(simple_generated_h) and insn-conditions.c from $(simple_generated_c). For all files remaining in those two lists, add insn-conditions.md to the generator command line. Give insn-constants.h/s-constants their own rules. Add rules for build/gencondmd.c, s-conditions, insn-conditions.md, s-condmd. (build/read-rtl.o): Depend on gensupport.h. (genprognormal): Include preds. (genprogearly): Rename genprognoprint; only difference is now that they don't link with $(BUILD_PRINT). * dummy-conditions.c: Delete. From-SVN: r110119
