Is it possible to view the types generated in the GHC.Prim module on my local machine?

The commentary[1] states that it is a virtual module and a source file including dummy declarations are available in this location: `libraries/base/GHC/Prim.hs`, however, upon downloading and building the latest GHC codebase I could not find this dummy file on my machine. Do I have to modify my Makefile somehow to generate these dummy types?

For building, I have followed the instructions mentioned here[2] and set `BuildFlavour = devel2`.

Thanks,
