+ * - The main test function performs several subtests.
+ * - For relaxed version, check bit operations on one core.
+ *   - Initialize valXX to specified values, then set each bit of valXX
+ *     to 1 one by one in "test_bitops_set_relaxed".
+ *
+ *   - Clear each bit of valXX to 0 one by one in "test_bitops_clear_relaxed".
+ *
+ *   - Function "test_bitops_test_set_clear_relaxed" checks whether each bit
+ *     of valXX can do "test and set" and "test and clear" correctly.
+ *
+ * - For C11 atomic barrier version, check bit operations on multi cores.
+ *   - Per bit of valXX is set to 1, then cleared to 0 on each core in
+ *     "test_bitops_set_clear". The function checks that once all lcores finish
+ *     their set_clear, the value of valXX would still be zero.
+ *
+ *   - The cores are waiting for a synchro which is triggered by the main test
+ *     function. Then all cores would do "rte_test_and_set_bitXX" or
+ *     "rte_test_and_clear_bitXX" at the same time, "countXX" which is checked
+ *     as the result later would inc by one or not according to the original
+ *     bit value.
