Created attachment 124003 [details] Specify that memcpy supports overlapping moves This is used to positive effect in some cases for performance of XArray etc. It would be a good idea to specify that VG_(memcpy) additionally supports overlapping areas if dest < src, since memcpy explicitly states the contrary.
