Comment 308 for bug 727064

> I'd personally suggest that glibc just alias memcpy() to memmove().

I think You aren't right :)

You suggest to provide *one* of many undocumented behaviours. What do You think do with other undocumented behaviours?

for example: memcpy can (or could) be used to propagate a pattern:

strcpy(buffer, "abc");
memcpy(buffer + 3, buffer, 100);

it will (or would) fill buffer by repeating "abcabcabc..."

Someone can invent the other undocumented variant. If You try provide all these variants You will have no time to do something in linux kernel.

I think that invalid (adobe's) code must be fixed anyway. memcpy shouldn't be alias to memmove.
