Given the following C code and assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c

#define rep(i,begin,end) for(int i=begin; i<end; i++)
#define revrep(i,begin,end) for(int i=begin; i>end; i--)
#define lld long long int

#define MOD 1000000007

lld f(lld a){
    return a<0 ? -1 * a : a;
}

int main(){
    lld n, m, l;
    scanf("%lld %lld", &n, &m);
    l = f(n - m);
    if(l <= 1){
        lld x=1, y=1, ans;
        while(n>1){
            x *= n;
            n--;
            x = x % MOD;
        }
        while(m>1){
            y *= m;
            m--;
            y = y % MOD;
        }
        ans = x * y % MOD;
        if(l == 0){
            ans = ans * 2 % MOD;
        }
