        * fold-const.c (twoval_comparison_p): Remove SAVE_P argument and don't
        look through SAVE_EXPRs with non-side-effects argument.  Adjust
        recursive calls.
        (fold_comparison): Adjust twoval_comparison_p caller, don't handle
        save_p here.

        * c-c++-common/ubsan/pr85213.c: New test.
