                    condition
           Product: gcc

  Target Milestone: ---

This is test2 from PR 94174:
```
void doit(void);
void test2(unsigned long a, unsigned long l)
{
  if (l + 1 == 0 || a <= l + 1)
    doit();
}
```

Extracted out since I have an idea on how to fix it based on what I did for PR
85605 .
