This does not make sense at all. float _4; float _7; if (tree_fits_shwi_p (rhs2)) return mult_by_coeff_cost (tree_to_shwi (rhs2), lhs_mode, speed); But I don't see that even call that. bool tree_fits_shwi_p (const_tree t) { return (t != NULL_TREE && TREE_CODE (t) == INTEGER_CST && wi::fits_shwi_p (wi::to_widest (t))); }
