Dear Alessandro Rubini,

No interest in the suggestion to not require count to be an exact multiple of 4/8?
Actually, I wrote about that in my patch 0/3.
Hm. Your argument was not exctly convincing, though.
Currently, I don't even know if this is going to be picked up, so I don't want to go too far -- and in that case I would like to measure things and be able to test for stupid bugs, so it takes time. Scrolling the video is an easy test for memcpy.
Sure this is going to ber picked uyp. And actually the implementation can be made even simpler doing both.
If there's interest, there's memmov to fix; it's used pretty often and it's the same idea as memcpy (well, scrolling should use memmove, in theory).
Volunteers welcome :-)
Best regards,
Wolfgang Denk
