Hi all, we have encountered a case of redundant copies still left in the final code and we would like to, at least, mitigate it. The original motivating case comes from a context where we have large vector registers. In that context, copies are expensive and we would like to avoid them as much as possible. This small testcase in C, similar to the original vector case, exposes the issue but using
