I think so.

Sure, but I've been wondering if it's necessary. Suppose we had some
hypothetical machine which is natively little-endian and has big- and
little-endian unaligned stores. We could match a big-endian store
with something like
instruct bigEndianStoreL(iRegL src, memory mem)
%{
match(Set mem (StoreL mem (ReverseBytesI src)));
format %{ "str.be $src, $mem\t" %}
so maybe there aren't any architectures where we'd gain any advantage
from intrinsifying such loads and stores?
