            Bug ID: 122251
           Summary: Missing LIM of aggegrate zeroing
           Product: gcc
           Version: 16.0
            Status: UNCONFIRMED
          Keywords: missed-optimization
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

```
struct s1
{
  int tl[12024];
};
struct s1 a;
void f(int n)
{
  for (int i = 0; i < n; i++)
  {
    a = (struct s1){};
  }
}
```

This should just be one memset of a instead of a loop.
