+;
+  %call = call i8* @memccpy(i8* %dst, i8* getelementptr inbounds ([10 x i8], [10 x i8]* @NoNulTerminator, i64 0, i64 0), i32 115, i64 %n) ; 115 is 's'
+  ret i8* %call
----------------
@efriedma ?

Maybe you meant this case?

e.g. n = 20

and we have block of memory "helloworld" "saaaattttt" and stop is char is 's'. In reality we copy 11 chars, but memcpy would copy n = 20 chars.
