2014-10-24 Richard Biener <rguenther@suse.de> * genmatch.c (expr::gen_transform): Use fold_buildN_loc and build_call_expr_loc. (dt_simplify::gen): Drop non_lvalue for GIMPLE, use non_lvalue_loc to build it for GENERIC. (decision_tree::gen_generic): Add location argument to generic_simplify prototype. (capture_info): New class. (capture_info::capture_info): New constructor. (capture_info::walk_match): New method. (capture_info::walk_result): New method. (capture_info::walk_c_expr): New method. (dt_simplify::gen): Handle preserving side-effects for GENERIC code generation. (decision_tree::gen_generic): Do not reject operands with TREE_SIDE_EFFECTS. * generic-match.h: New file. * generic-match-head.c: Include generic-match.h, not gimple-match.h. * match.pd: Add some constant folding patterns from fold-const.c. * fold-const.c: Include generic-match.h. (fold_unary_loc): Dispatch to generic_simplify. (fold_ternary_loc): Likewise. (fold_binary_loc): Likewise. Remove patterns now implemented by generic_simplify. * gimple-fold.c (replace_stmt_with_simplification): New function. (fold_stmt_1): Add valueize parameter, dispatch to gimple_simplify. (no_follow_ssa_edges): New function. (fold_stmt): New overload with valueization hook. Use no_follow_ssa_edges for the overload without hook. (fold_stmt_inplace): Likewise. * gimple-fold.h (no_follow_ssa_edges): Declare. From-SVN: r216631
