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

```c
#include<stdio.h>
#include<stdlib.h>
struct goods {
  int profit;
  int weight;
};
int **C;
struct goods *item;
int uknapsack(int size, int limit);
int main(void)
{
  int i, n, w;
  scanf("%d%d", &n, &w);
  C = (int**)malloc(sizeof(int*) * (n + 1));
  item = (struct goods*)malloc(sizeof(struct goods) * (n + 1));
  for (i = 0; i <= n; i++) {
    C[i] = (int*)malloc(sizeof(int) * (w + 1));
    C[i][0] = 0;
    if (i) scanf("%d%d", &item[i].profit, &item[i].weight);
  }
  for (i = 0; i <= w; i++) C[0][i] = 0;
  printf("%d\n", uknapsack(n, w));
  for (i = 0; i <= n; i++) free(C[i]);
  free(C);
  free(item);
}
int uknapsack(int size, int limit)
{
  int i, j;
  for (i = 1; i <= size; i++) {
    for (j = 1; j <= limit; j++) {
      C[i][j] = C[i-1][j];
      if (item[i].weight > j) continue;
      if (item[i].profit + C[i][j-item[i].weight] > C[i-1][j]) {
        C[i][j] = item[i].profit + C[i][j-item[i].weight];
      }
    }
  }
  return C[size][limit];
}
```

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

```c
#include<stdio.h>
#include<stdlib.h>
struct goods {
  int profit;
  int weight;
};
int **C;
struct goods *item;
int uknapsack(int size, int limit);
int main(void)
{
  int i, n, w;
  scanf("%d%d", &n, &w);
  C = (int**)malloc(sizeof(int*) * (n + 1));
  item = (struct goods*)malloc(sizeof(struct goods) * (n + 1));
  for (i = 0; i <= n; i++) {
    C[i] = (int*)malloc(sizeof(int) * (w + 1));
    C[i][0] = 0;
    if (i) scanf("%d%d", &item[i].profit, &item[i].weight);
  }
  for (i = 0; i <= w; i++) C[0][i] = 0;
  printf("%d\n", uknapsack(n, w));
  for (i = 0; i <= n; i++) free(C[i]);
  free(C);
  free(item);
}
int uknapsack(int size, int limit)
{
  int i, j;
  for (i = 1; i <= size; i++) {
    for (j = 1; j <= limit; j++) {
      C[i][j] = C[i-1][j];
      if (item[i].weight > j) continue;
      if (item[i].profit + C[i][j-item[i].weight] > C[i-1][j]) {
