This optimization was introduced by #70469.

Like AArch64, we allow tail expansions for 3 on RV32 and 3/5/6
on RV64.

This can simplify the comparison and reduce the number of blocks.

As far as I can, the reference optimization is assuming that unaligned loads are legal and fast. This is not true for us. As such, this optimization is not sound.

Please, stop posting additional memcmp enable patches until you've addressed the soundness issues in that code with unaligned loads. It a waste of your time, and a waste of reviewers time.

What are the soundness issues? I thought we only had costing issues?

The code in RISCVTTIImpl::enableMemCmpExpansion currently checks ST->enableUnalignedScalarMem() before enabling any expansion.

Gah, you're correct! I read the check code too fast and apparently mentally placed the negate in the wrong place. Please ignore my comment on this review entirely.
