Hmm, so we accept wide-char literals as well here? >Would it be enough to just clear their type during free lang data or >something similar? I guess so. Maybe do that during gimplification already? Wonder how we pretty print asms then when we mangle their types. Note the original patch is OK as-is I just wondered why we bother to even keep the asm constrains as something different than a char *. Richard. > > Jakub
