Use the * verbose (-v) option to see all the instructions and whether or not they * decoded successfully. */ int test__insn_x86(struct test *test __maybe_unused, int subtest __maybe_unused) { int ret = 0; if (test_data_set(test_data_32, 0)) ret = -1; if (test_data_set(test_data_64, 1)) ret = -1; return ret; }
