2014-10-17 Richard Biener <rguenther@suse.de>
* fold-const.c (fold_comparison): Remove redundant constant
folding and operand swapping.
(fold_binary_loc): Do comparison operand swapping here.
(fold_ternary_loc): Canonicalize operand order for
commutative ternary operations.
* tree.c (commutative_ternary_tree_code): Add DOT_PROD_EXPR
and FMA_EXPR.
