Immediately we suspect that the file is auto-generated during build.
So we do a shell find in the output directory:
```
find . -name OpClass.hh
```
This leads us to: ./build/ARM/enums/OpClass.hh
Open the file, look for interesting unique identifiers, and git grep
that on main source.
So:
```
git grep No_OpClass
```
Too many stats.txt hits on tests, so grep them out:
```
git grep No_OpClass | grep -v stats.txt
```
Inspect about 40 hits, most are ovbiously usage instead of
definitions, but this looks promising:
```
src/cpu/FuncUnit.py
```
as it contains:
```
class OpClass(Enum):
vals = ['No_OpClass', 'IntAlu', 'IntMult', 'IntDiv', 'FloatAdd',
```
ctag navigate the definition of Enum base class indicates that it gets
processed by pybind11 to generate the headers.
