real.h (HONOR_NANS): Replace macro with 3 overloaded declarations.
2014-12-10 Marc Glisse <marc.glisse@inria.fr> * real.h (HONOR_NANS): Replace macro with 3 overloaded declarations. * real.c: Include rtl.h and options.h. (HONOR_NANS): Define three overloads. * builtins.c (fold_builtin_classify, fold_builtin_unordered_cmp): Simplify argument of HONOR_NANS. * fold-const.c (combine_comparisons, fold_truth_not_expr, fold_cond_expr_with_comparison, merge_truthop_with_opposite_arm, fold_comparison, fold_binary_loc): Likewise. * ifcvt.c (noce_try_move, noce_try_minmax): Likewise. * ipa-inline-analysis.c (add_clause, set_cond_stmt_execution_predicate): Likewise. * match.pd: Likewise. * rtlanal.c (may_trap_p_1): Likewise. * simplify-rtx.c (simplify_const_relational_operation): Likewise. * tree-if-conv.c (parse_predicate): Likewise. * tree-ssa-ccp.c (valid_lattice_transition): Likewise. * tree-ssa-ifcombine.c (ifcombine_ifandif): Likewise. * tree-ssa-phiopt.c (minmax_replacement, neg_replacement): Likewise. * tree-ssa-reassoc.c (eliminate_using_constants): Likewise. * tree-ssa-tail-merge.c (gimple_equal_p): Likewise.
