--- Comment #39 from Tim Ruffing <public at timruffing dot de> --- (In reply to Rich Felker from comment #36) > Our memcpy is not written in asm but in C, and it has the restrict qualifier > on src and dest. For my curiosity, can you point me to this implementation? I couldn't find a memcpy with restrict in the libc source, but I suspect that's just because I'm not familiar with the code base.
