Is there some way to do an #if to only use the raw hex on assemblers without support today?

I'm not aware of, do we have sth like LLVM version identifier defined in our code base?

I think this chunk is meant to be converted to MOV instructions once we have LLVM with official APX supports, and the code may not have actual use cases until we have machines with APX.

@tannergooding, could you share some thoughts on this?

I think its fine as is, I don't think its worth supporting code that we can't reliably test and maintain in CI at this point in time.

Rather, lets just have the one path and update when the toolchain can finally be updated to LLVM 19/20 or later
