fold-const.c (fold_cond_expr_with_comparison): New function, extracted from fold.
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
