match.pd: Implement conditional expression patterns.
2014-11-13 Richard Biener <rguenther@suse.de>
* match.pd: Implement conditional expression patterns.
* tree-ssa-forwprop.c (forward_propagate_into_cond): Remove
them here.
(combine_cond_exprs): Remove.
(pass_forwprop::execute): Do not call combine_cond_exprs.
* fold-const.c (fold_ternary_loc): Remove patterns here.
(pedantic_omit_one_operand_loc): Remove.
