2004-06-21 Paolo Bonzini <bonzini@gnu.org> * fold-const.c (fold_cond_expr_with_comparison): New function, extracted from fold. (fold): Extract code to fold A op B ? A : C, use it to fold A op B ? C : A. Really optimize A & N ? N : 0 where N is a power of two. Avoid relying on canonicalization and recursion for foldings of COND_EXPR to happen. From-SVN: r83428
