--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

Here is a C++ testcase which does something similar to `-finstrument-functions`
does to the IR (`-Os -fnon-call-exceptions -ftrapv` is only needed):
```
struct s { ~s(); };
void
h (unsigned char *data, int c)
{
  s a1;
  while (c)
    {
      int m = *data++ << 8;
      m += *data++;
    }
}
```
