Open Source Summit + Embedded Linux Conference North America 2026

GCC is default toolchain for Linux based systems, ever since the Linux Distributions were being put together from early days of Linux. However, there have been important developements in compiler technologies and LLVM project has come along. The LLVM infrastructure has been used to build various different compilers for different languages, Clang is the C/C++ static compiler and rust also uses LLVM. There is LLD ( LLVM Linker ) LLDB, ( LLVM Debugger ). binutils like objcopy, objdump, strip etc. are also added. C/C++ compiler runtime in compiler-rt/libc++ has matured as well. The compiler has been used to build Linux Kernel already, However, it can be used to build full Embedded Linux Systems using infrastructure like Yocto project. This talk will showcase that a Linux system can be built completely using LLVM toolchain, replacing the compiler, compiler-runtime, binutils with LLVM built tools. In addition it will also discuss the modern tooling provided with LLVM and Clang and static analyser ( clang-scan ), clang-tidy, clanf-format etc. show-casing additional tooling that can be used by developers e.g. sanitizers.
