            Bug ID: 125799
           Summary: load commonizing and store elimination combing
           Product: gcc
           Version: 16.0
            Status: UNCONFIRMED
          Keywords: missed-optimization
          Severity: enhancement
          Priority: P3
         Component: tree-optimization
          Assignee: pinskia at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---

Take:
```
int f(int *a, int *c, int *d, int e)
{
  int t;
  if (e)
  {
    *a = 1;
    t = *c;
  }
  else
  {
    *a = 0;
    t = *d;
  }
  return t;
}

```
We should be able to optimize this to a conditional move and a ccset but
currently we do.
