...instructions. Conveniently, the authors of that research paper actually implemented their model in a fork of LLVM! (found here: https://github.com/stedolan/llvm <https://github.com/stedolan/llvm>). The model is essentially implemented with just two additions: a new calling convention called “swapstack”, and a new intrinsic function called “newstack”. They demonstrate that these two primitives can be used not just for user-level context-switching, but also for implementing efficient coroutines and generators, all while taking advantage of existing LLVM optimizations. I encourage you to read the e...
