2010-11-04 Richard Guenther <rguenther@suse.de> Richard Henderson <rth@redhat.com> * tree.def (FMA_EXPR): New tree code. * expr.c (expand_expr_real_2): Add FMA_EXPR expansion code. * gimple.c (gimple_rhs_class_table): FMA_EXPR is a GIMPLE_TERNARY_RHS. * tree-cfg.c (verify_gimple_assign_ternary): Verify FMA_EXPR types. * tree-inline.c (estimate_operator_cost): Handle FMA_EXPR. * gimple-pretty-print.c (dump_ternary_rhs): Likewise. * tree-ssa-math-opts.c (convert_mult_to_fma): New function. (execute_optimize_widening_mul): Call it. Reorganize to allow dead stmt removal. Move TODO flags ... (pass_optimize_widening_mul): ... here. * flag-types.h (enum fp_contract_mode): New enum. * common.opt (flag_fp_contract_mode): New variable. (-ffp-contract): New option. * opts.c (common_handle_option): Handle it. * doc/invoke.texi (-ffp-contract): Document. * tree.h (fold_fma): Declare. * builtins.c (fold_fma): New function. (fold_builtin_fma): Likewise. (fold_builtin_3): Call it for fma. * fold-const.c (fold_ternary_loc): Fold FMA_EXPR. * optabs.c (optab_for_tree_code): Handle FMA_EXPR. * config/i386/sse.md (fms<mode>4, fnma<mode>, fnms<mode>4): New expanders. * doc/md.texi (fms<mode>4, fnma<mode>, fnms<mode>4): Document new named patterns. * genopinit.c (optabs): Initialize fms_optab, fnma_optab and fnms_optab. * optabs.h (enum optab_index): Add OTI_fms, OTI_fnma and OTI_fnms. (fms_optab, fnma_optab, fnms_optab): New defines. * gimplify.c (gimplify_expr): Handle binary truth expressions explicitly. Handle FMA_EXPR. * tree-vect-stmts.c (vectorizable_operation): Handle ternary operations. * gcc.target/i386/fma4-vector-2.c: New testcase.
