A nice harsh undefined behaviour. We will clean the entire userland of the remaining issues in this catagory, then switch to the optimised memcpy which skips the memmove check. I tried to cut this change into pieces, but testing each sub-step on every architecture is too time consuming and mindnumbing. ok miod One of these optimized stubs creates some incredibly subtle damage, 2014-11-20T21:51:02Z deraadt deraadt@openbsd.org 2014-11-20T21:51:02Z urn:sha1:d1a57517ee8d16db5fa9ffc7f8a82afb73782cbe causing as(1) to create a wrong nop-sled for text segment aligns.

Depending on the function, this gives us some speedup in userland. ok deraadt@, no objections from miod@
