> @lenary Any thoughts on what is going so wrong in aea-erratum-fix.ll? SimplifyDemandedBits does tend to mess with specific patterns that this might be depending on.

A quick look suggests you shouldn't be worried about it. I need to revisit the tests to simplify them, because the test is just checking the inputs to the aese/aesd instructions are from particular instructions, rather than all the prior logic, and I had failed to notice how complex that test had become.
