--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Hmm, looks like this works for aarch64, arm, power.
Also it does nothing to do with tail calls.
Even:
```
void bar0 (int);
void bar1 (int);
void g();
void
foo (int i)
{
switch (i)
{
case 0: bar0 (i); break;
case 1: bar1 (i); break;
}
g();
}
```
Fails to work on x86_64 but works on aarch64 and other targets.
