--- Comment #1 from Pokechu22 <pokechu022+gccbugzilla at gmail dot com> ---
Here are a few cases that would be useful to include in a test:

```
return (!false && (false ? a : b));
return (!true && (false ? a : b));
return (!false || (false ? a : b));
return (!true || (false ? a : b));
return (x && (y ? a : b));
return (x || (y ? a : b));
```

As an aside, `(false | (false ? a : b))` (where a is bool and b is Foo) use=
d to
cause an ICE (confirmed in 4.7.4, 4.8.1, and 5.5). This was fixed in or bef=
ore
6.1. I can't find a bug report corresponding to that issue either, but it
probably should be verified that that doesn't regress either.=
