    Hi I'm trying to get Clang to generate an assembly file from my C++ file and for some reason clang can't read D3DXMATRIXA16 despite being defined in  DBOData.h 

![image](https://user-images.githubusercontent.com/94544102/175806157-18c82114-e0aa-42c4-b93a-6b9a323014f1.png)

any ideas on why clang can't read this definition?
