I think Erich has the core of it, but picked a poor example.
```c++
struct S { char : 3; unsigned long long l; };
```
emits
```
{empty !u8i, !u64i}
```
However, this example shows what he means:
```c++
struct C { int a : 3; int : 0; int : 3; };
```
emits
```
{!u8i, pad !cir.array<!u8i x 3>, empty !u8i, pad !cir.array<!u8i x 3>}
```
