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

```c
/* ex 5_4
   yy8332 */

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

int main(void){
  char str1[11], *str2;
  int len1, len2, ans, i;

  //入力読み取り
  scanf("%s", str1);

  len1 = strlen(str1);

  //最長部分文字列の取得
  ans = 0;

  for(i = 0; i < len1; i++){
    if(str1[i] == 'A' || str1[i] == 'C' || str1[i] == 'G' || str1[i] == 'T'){
      len2 = 0;
      str2 = &str1[i];
      while(*str2 == 'A' || *str2 ==  'C' || *str2 == 'G' || *str2 == 'T'){
        len2++;
        str2++;
      }
      i += len2 - 1;
    }
    if(len2 > ans){
      ans = len2;
    }
  }

  //出力
  printf("%d\n", ans);

  return 0;
}
```
