Hi Juzhe,
I think an extra param might be too intrusive. I would expect normal
hardware implementations to support unaligned accesses (but they might
be slow which should be covered by costs) and only rarely have hardware
that doesn't support it and raises exceptions.
Therefore I would suggest t
o-strict-align) is not appropriate, which means I
need additional compile option.

Previously, I removed the movmisalign pattern to fix the execution FAILs in
this commit:
https://github.com/gcc-mirror/gcc/commit/f7bff24905a6959f85f866390db2fff1d6f95520
I was thinking that RVV doesn't allow misaligned at the beginning so I removed
that pattern.
However, after deep investigatio
