        * tree-ssa-dom.c (thread_across_edge): Make sure that the condition
        of a COND_EXPR is folded before calling fold on the whole rhs of a
        conditional assignment.
        * doc/tree-ssa.texi: Update the GIMPLE grammar for a valid rhs to
        document that a COND_EXPR may appear there.

        testsuite/
        * gcc.dg/pr23049.c: New test.

        * gcc.dg/ucnid-4.c: Fix test.
