OpenIoT & ELC 2016

A system compiler is a core piece of tools when building any operating system platform. For long GCC has been de-facto system compiler for embedded Linux systems. In this presentation, Khem will explain and demonstrate how clang/llvm based cross compilers can be used to build key components of Embedded Linux stack using the Linux kernel. Thus far clang has been used to compile applications on linux and there has been no unified approach where clang can be used selectively for packages through out the platform components. This presentation will introduce how Yocto Project/OpenEmbedded has architectured the way in for Clang to be present as alternative C/C++ compiler and also is made part of application SDKs along with GCC based cross compiler. Which makes it possible for application and system programmers to use Clang at their will. It also covers what is yet to be done.
