Open Source Summit + Embedded Linux Conference + OSPOCon 2021

The importance of an optimized toolchain in current open source projects is a reality. The performance and security of a project could be improved by new features in the compiler, linker, or binary tools available to developers and users. This presentation aims to show the best-known methods to build and use the latest version of the toolchains from your workstation to containerized applications, as well as the incoming new toolchain features for 2021. Among those new features, the GNU toolchain projects release features like a dynamic linker for multiple architectures where is possible to loads optimized implementations of shared objects. An extra level of security analysis is implemented to detect buffer overflow errors. At the same time, Deep Learning applications can use new SIMD instruction such as Vector Neural Network Instructions (AVX512 VNNI) and Advanced Matrix Extension (AMX) for x86 platforms. Having a better understanding of the toolchains allows showcasing the best of CPU architecture technology for users' applications as well as increase the spectrum of coding tools available for open source developers.
