GNU toolchains are used widely for building embedded targets. In the past year, I led an effort to port a real world embedded project to use the Clang/LLVM toolchain. In this talk, I will present the motivation, challenges faced, results, and the future directions the LLVM community must consider in supporting the embedded development scenarios. This talk will offer a blueprint for embedded projects to transition to using LLVM toolchain and take advantage of the incredible work carried out by the LLVM community.
