> Yes, I actually updated the description on Phab, but it didn't send out an email notification for that. Basically, the pimpl has a unique_ptr<PassInfo>, and PassSupport.h already includes PassRegistry.h, so I couldn't have PassRegistry.h include PassSupport.h to get this class.

Yep - that's what I figured. Just checking.
In theory if the ctor and dtor are out of line, a forward declaration should still be sufficient for the unique_ptr<PassInfo> member to be declared (if the dtor or ctor are inline, then they'd need to emit unique_ptr's dtor which would need to emit a call to PassInfo's dtor, etc...) but as you say, better to pull it into a separate file anyway, and include it in the right places. Looks good.
