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

[Dávid Bolvanský via Phabricator via llvm-commits]

xbolva00 added a comment.

but  -fno-builtin is maybe too aggresive? somebody should benchmark kernel with/without it.

Anyway, I thought -fno-builtin-memccpy also could disable it, but no.. -fno-builtin-snprintf works.
