I have created an enableBigEndian() hook which the targets can use if they want to use big-endian. I ran the tests locally and the tests passed. But some of the unit tests fail when I submitted the patch which is not related to globalisel. What could be the reason for that?

I am new to compilers so wanted to know where I am going wrong.
