Very cool to see my project posted here!

The motivation behind a lot of this was to have community LLVM implementations of runtime functions normally provided by the vendor libraries (C math, printf, malloc), but if you implement one function you may as well implement them all.

Realistically, the infrastructure behind this project is more relevant than the C library calls themselves. The examples in the linked documentation can be used for any arbitrary C/C++ just as well as the LLVM C library, it's simply statically linking. This is what allowed me to compile and run more complicated things like libc++ and DOOM on the GPU as well. The RPC interface can also be used to implement custom host services from the GPU, or used to communicate between any two shared memory processes.
