        PR target/43610
        * optabs.c (prepare_float_lib_cmp): Allow reversing the comparison
        even if !FLOAT_LIB_COMPARE_RETURNS_BOOL.  Always compute true_rtx and
        false_rtx.  Use false_rtx to compute the correct *ptest for reversed
        comparisons for which !FLOAT_LIB_COMPARE_RETURNS_BOOL.
