@Hamlin-Li We can also just go with a risv impl for now, and then we can do x64 and aarch64 separately.

Does this patch not affect the IR rules of the tests we have already in the code base? With an improvement, there is usually a chance to add IR rules to existing tests, or add new tests with new IR rules.
