--- Comment #3 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
The manual says:
> @deftypefn {Target Hook} bool TARGET_SLOW_UNALIGNED_ACCESS ...
> ...
> The hook must return true whenever @code{STRICT_ALIGNMENT} is true.
But STRICT_ALIGNMENT must be true because even when there are fast unaligned
load operations, we cannot use normal mov<mode> patterns, but must use
mov_misalign<mode>.
So it looks like we can't change anything here.
