[PATCH] D67986: [InstCombine] snprintf (d, size, "%s", s) -> memccpy (d, s, '\0', size - 1), d[size - 1] = 0

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

You could do something like `if (!memccpy (d, s, '\0', size - 1)) d[size - 1] = 0;`, I guess.  That's a few more instructions that I'd really like, but I don't see a better alternative.
