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

```c
#include <stdio.h>

/** Application main entry point. */
int main (
  int     argc,
  char  * argv[ ]
  )
{
  for ( ; ; )
  {
    char d[ 4 ][ 8 ];

    scanf ( " %s", d[ 0 ] );
    if ( d[ 0 ][ 0 ] == '0' )  break ;
    scanf ( " %s", d[ 1 ] );
    scanf ( " %s", d[ 2 ] );

    if ( d[ 0 ][ 0 ] != '+'
      && ( ( d[ 0 ][ 0 ] == d[ 0 ][ 1 ] && d[ 0 ][ 0 ] == d[ 0 ][ 2 ] )
        || ( d[ 0 ][ 0 ] == d[ 1 ][ 0 ] && d[ 0 ][ 0 ] == d[ 2 ][ 0 ] ) ) )
    {
      printf ( "%c\n", d[ 0 ][ 0 ] );
    }
    else if ( d[ 2 ][ 2 ] != '+'
      && ( ( d[ 2 ][ 2 ] == d[ 2 ][ 1 ] && d[ 2 ][ 2 ] == d[ 2 ][ 0 ] )
        || ( d[ 2 ][ 2 ] == d[ 1 ][ 2 ] && d[ 2 ][ 2 ] == d[ 0 ][ 2 ] ) ) )
    {
      printf ( "%c\n", d[ 2 ][ 2 ] );
    }
    else if ( d[ 1 ][ 1 ] != '+'
           && ( ( d[ 1 ][ 1 ] == d[ 1 ][ 0 ] && d[ 1 ][ 1 ] == d[ 1 ][ 2 ] )
             || ( d[ 1 ][ 1 ] == d[ 0 ][ 1 ] && d[ 1 ][ 1 ] == d[ 2 ][ 1 ] )
             || ( d[ 1 ][ 1 ] == d[ 0 ][ 0 ] && d[ 1 ][ 1 ] == d[ 2 ][ 2 ] )
             || ( d[ 1 ][ 1 ] == d[ 0 ][ 2 ] && d[ 1 ][ 1 ] == d[ 2 ][ 0 ] ) ) )
    {
