Okay, I have a proposal: in the morning, I will cut down the size of this patch by restricting it to MustAlias. Then, I could run llvm-test-suite offline with the remainder of the patch (i.e. the PartialAlias) on the RISC-V target and check for binary changes: if there are any, I will post the diff with a follow up patch.
