I think we handle the other cases, for code optimized for size we go for ix86_size_memcpy and ix86_size_memset tables that say inline all with rep movsb. We do not inline strlen since the way it is implemented gets too long (short inline version would be welcome). I will look through backend, but if you are aware of more checks like one in ix86_expand_cmpstrn_or_cmpmem which disable size optimization even at -Os, let me know. They are not that easy to find...
