Is this like llbuild? https://www.youtube.com/watch?v=b_T-eCToX1I https://github.com/apple/swift-llbuild I remember watching the talk awhile ago, but haven't kept up with its progress. It's about using LLVM as a library to eliminate duplicate work, as far as I remember. I think it was for C++ as well as Swift.

there is llbuild... https://github.com/apple/swift-llbuild llbuild is a set of libraries for building build systems. Unlike most build system projects which focus on the syntax for describing the build, llbuild is designed around a reusable, flexible, and scalable general purpose build engine capable of solving many "build system"-like problems. The project also includes additional libraries on top of that engine which provide support for constructing bespoke build systems (like swift build) or for building from Ninja manifests.

https://github.com/apple/swift-llbuild may be too low-level for what you envision, but captures a lot of your ideas, I think. https://llvm.org/devmtg/2016-11/#abstracts has a presentation. It focuses on compiling with clang, but the system is more flexible. Slides at https://llvm.org/devmtg/2016-11/Slides/Dunbar-NewArchitectur..., matching video is at https://youtu.be/b_T-eCToX1I.
