--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
For stores I think the patch already allows that, that is the
if (GET_CODE (*x) == SET && &SET_DEST (*x) == data)
return 1;
in there (the reason why I've added it was that for the misaligned store insns
with UNSPEC_STOREU the misaligned MEM is in SET_DEST and SET_SRC just contains
some rtl with UNSPEC_STOREU embedded somewhere in it.
So, would you like:
if (GET_CODE (*x) == SET && (&SET_DEST (*x) == data || &SET_SRC (*x) ==
data))
return 1;
? That would IMHO handle simple loads from misaligned MEM too.
