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

```c
/* ex 9_2
   unomi */

#include<stdio.h>
#include<stdlib.h>
#include<string.h>

//リストのノード（スタック内の各データ）の定義
typedef struct node{
    char elem;
    struct node *next;
} node;

//スタックにデータを追加
void push(node **first, char elem){
    //追加する分の領域を確保
    node *new = calloc(1, sizeof(node));
    if(new == NULL) exit(1);
    new->elem = elem;  // 要素を代入
    new->next = *first;  // 新しいノードの指す先にfirstの値を代入
    *first = new;  // firstを新しいノードに設定
}

//スタックからデータを取り出す
char pop(node **first){
    char elem;
    node *tmp = *first;
    if(tmp == NULL) return 2;  
    elem = tmp->elem;  //要素を取り出し
    *first = tmp->next;  // firstを手前に
    //取り出したノードのメモリを解放
    free(tmp);
    return elem;
}

int main(void){
    char input[10*10*10*10*10], trash;
    int i=1, j=0, k=0, cnt=0, prev_cnt=1;

    //最初のノードの指す先を設定
    node *first = NULL;

    // 入力の取得
    scanf("%s",input);

    // 最初の箱をスタックにpush
    push(&first, input[0]);

    while(input[i] != '\0'){
        //printf("step:%d  %c\n",i,input[i]);
        if(first != NULL && first->elem != input[i]){
            trash = pop(&first);
            //puts("###");
            //printf("%c %c\n",input[i],first->elem);
            cnt+=2;
        }
        else push(&first, input[i]);
        i++;
    }

    
    printf("%d\n",cnt);

    return 0;
}

```
