Actually, this test is similar to the one on line 16. The test on line 14 is for the compile with `-maix32` and the setting of `OBJECT_MODE` inherited from the LIT environment which is `OBJECT_MODE=64` set in `lit.cfg.py`. The difference between these two is with and without the explicit `OBJECT_MODE` setting on the command. The test on line 4 is to compile with `OBJECT_MODE` unset. Anyway, I will remove this on.
