slice - Is there analog of memset in go?

Question

In C++ I can initialize an array with some value using memset:

const int MAX = 1000000;
int is_prime[MAX]

memset(is_prime, 1, sizeof(is_prime))

What memset does, crudely can be described as filling the array with some value, but doing this really really fast.

In go I can do is_prime := make([]int, 1000000), but this will create a slice with all 0, in the similar manner I can use new([1000000]int), but nothing will allow me to create an array/slice with all 1 or any other non-zero element.

Of course I can use a loop to populate it with the value later, but the main purpose of memset is that it is way way faster than the loop.

So do Go programmers have a memset analog (fast way of initializing array to some non-zero value)?
