Thanks Shiva. I'm updating the patch series in a way that adds much more exhaustive testing for the `*W` patterns and fleshes out patterns for cases like this. I mused on the RV64I patch review thread whether there was something smarter to do here - maybe some canonicalisation. But regardless of that, it's helpful to have more exhaustive tests.
