Author: jsm28 Date: Mon Mar 30 01:50:44 2009 New Revision: 145272 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=145272 Log: PR rtl-optimization/323 * c-common.c (c_fully_fold, convert_and_check, c_common_truthvalue_conversion): Handle EXCESS_PRECISION_EXPR. (c_fully_fold_internal): Disallow EXCESS_PRECISION_EXPR. * c-common.def (EXCESS_PRECISION_EXPR): New. * c-cppbuiltin.c (builtin_define_float_constants): Define constants with enough digits for long double. * c-lex.c (interpret_float): Interpret constant with excess precision where appropriate. * c-opts.c (c_common_post_options): Set flag_excess_precision_cmdline. Give an error for -fexcess-precision=standard for C++ for processors where the option is significant. * c-parser.c (c_parser_conditional_expression): Handle excess precision in condition. * c-typeck.c (convert_arguments): Handle arguments with excess precision. (build_unary_op): Move excess precision outside operation. (build_conditional_expr): Likewise. (build_compound_expr): Likewise. (build_c_cast): Do cast on operand of EXCESS_PRECISION_EXPR. (build_modify_expr): Handle excess precision in RHS. (convert_for_assignment): Handle excess precision in converted value. (digest_init, output_init_element, process_init_element): Handle excess precision in initializer. (c_finish_return): Handle excess precision in return value. (build_binary_op): Handle excess precision in operands and add excess precision as needed for operation. * common.opt (-fexcess-precision=): New option. * config/i386/i386.h (X87_ENABLE_ARITH, X87_ENABLE_FLOAT): New. * config/i386/i386.md (float<SSEMODEI24:mode><X87MODEF:mode>2): For standard excess precision, output explicit conversion to and truncation from XFmode. (*float<SSEMODEI24:mode><X87MODEF:mode>2_1, *float<SSEMODEI24:mode><X87MODEF:mode>2_i387_with_temp, *float<SSEMODEI24:mode><X87MODEF:mode>2_i387, two unnamed define_splits, floatdi<X87MODEF:mode>2_i387_with_xmm, two unnamed define_splits, *floatunssi<mode>2_1, two unnamed define_splits, floatunssi<mode>2, add<mode>3, sub<mode>3, mul<mode>3, divdf3, divsf3, *fop_<mode>_comm_i387, *fop_<mode>_1_i387, *fop_<MODEF:mode>_2_i387, *fop_<MODEF:mode>_3_i387, *fop_df_4_i387, *fop_df_5_i387, *fop_df_6_i387, two unnamed define_splits, sqrt<mode>2): Disable where appropriate for standard excess precision. * convert.c (convert_to_real): Do not shorten arithmetic to type for which excess precision would be used. * defaults.h (TARGET_FLT_EVAL_METHOD_NON_DEFAULT): Define. * doc/invoke.texi (-fexcess-precision=): Document option. (-mfpmath=): Correct index entry. * flags.h (enum excess_precision, flag_excess_precision_cmdline, flag_excess_precision): New. * langhooks.c (lhd_post_options): Set flag_excess_precision_cmdline. * opts.c (common_handle_option): Handle -fexcess-precision=. * toplev.c (flag_excess_precision_cmdline, flag_excess_precision, init_excess_precision): New. (lang_dependent_init_target): Call init_excess_precision. * tree.c (excess_precision_type): New. * tree.h (excess_precision_type): Declare. ada: * gcc-interface/misc.c (gnat_post_options): Set flag_excess_precision_cmdline. Give an error for -fexcess-precision=standard for processors where the option is significant. fortran: * options.c (gfc_post_options): Set flag_excess_precision_cmdline. Give an error for -fexcess-precision=standard for processors where the option is significant. java: * lang.c (java_post_options): Set flag_excess_precision_cmdline. Give an error for -fexcess-precision=standard for processors where the option is significant. testsuite: * gcc.target/i386/excess-precision-1.c, gcc.target/i386/excess-precision-2.c, gcc.target/i386/excess-precision-3.c, gcc.target/i386/excess-precision-4.c, gcc.target/i386/excess-precision-5.c, gcc.target/i386/excess-precision-6.c: New tests.
