[PATCH] D17889: [MachineCopyPropagation] Expose more dead copies across instructions with regmasks

Thanks Jun for checking where the copy came from.
That being said, isn't this case already handled?
And if it is not, could you add a test case for it. None of the test cases you are adding reproduce that example.

Thanks,
