[PATCH] D67986: [InstCombine] snprintf (d, size, "%s", s) -> memccpy (d, s, '\0', size).

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Do we have accurate TLI information for memccpy?  Not sure exactly how widely available it is.

If we're going to start generating memccpy calls, do we need to implement optimizations for it?  For example, memccpy of a constant string can be transformed to memcpy.
