Dear Matthias Weisser,
In message 4DA360A9.10401@arcor.de you wrote:
I can't come up with an example where this may produce a problem but who knows which exotic hardware is out there which expects that a memcpy with identical src and dst addresses is executed exactly in that way. But maybe we can ignore this and let these exotic boards come up with a solution handling that special situation.
Right.
While we are at it, we should do the same with bcopy() and memmove(), too.
Maybe I can post a patch tomorrow. The only thing which I can't handle are architecture specific memcpy/memmove/... functions besides ARM.
That's fine. Optimized arch specific code probably already implements such a shortcut anyway.
Best regards,
Wolfgang Denk
