Embedded systems software, which for the purposes of the workshop we'll define as ranging from a no-operating system microcontroller project, to embedded linux, has some requirements that are different from userspace software that runs on top of an OS. The purpose of the workshop is to focus on the embedded specific requirements and coming up with an approach for addressing these in the open-source llvm-project. The focus will be on sharing knowledge of downstream solutions and discussing requirements and design of upstream features rather than a tutorial for how to build a toolchain for embedded systems.
