Hmmm... this skips quite a bit which causes obvious discomfort.
There's quite a bit inside of the function itself that get skipped too, which
is a little concerning, particularly with us all-over-the-place.
IMO, I think a better formulation for the purposes of readability of this would
to better integrate these in this function.
~12956 (though perhaps higher than 12950?):
```
// Some comment about how other attributes/etc are all irrelevant for the
purposes of SYCL.
if (LangOpts.SYCLIsDevice)
return FD->hasAttr<SYCLKernelEntryPointAttr>() ||
FD->hasAttr<SYCLExternalAttr>();
```
Then around 12990:
```
// Some comment about how global variables should never be emitted
if(LangOpts.SYCLIsDevice) return false;
```
That way this requires MUCH less tea-leaf reading of the rest of the function
to figure out when/why we're excluding these.
