[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.

BTW, we transform snprintf(d, s, "%s" , ...) into two calls - memcpy + strlen - and nobody is concerned about code size increase anyway.

So I dont think code size is problem here. Various InstCombine transformations produces two calls. (here it is just call + select..).

I will continue with this patch.
