[llvm-dev] What is the right lowering for misaligned memory access?

Thank you all. That is an exceptionally clear response.

There the usual tradeoffs in the implementation. Simplicity / correctness /
performance / memory / dev time. Deleting the instructions fails on
correctness and per byte is too slow. I'll write something reasonable for
the ISA.
