DragonFFI: C Foreign Function Interface and JIT using Clang/LLVM
- DragonFFI is a C Foreign Function Interface (FFI) library written in C++ and based on Clang/LLVM. It allows any language to call C functions thought the provided APIs and bindings.

The Salami Method
- The Salami Method finely distinguishes between the different aspects and layers required for exposing platform-independent C++ on different “specific” platforms. At its extreme it strives to create a single, thin, transparent layer for each such aspect so that each layer is more easily built, tested, debugged, managed and maintained.
