Open Source Summit North America 2023

Innovation is the fuel and power of open-source projects. To propel that innovation, every year the toolchain community focuses on creating new tools for open-source developers. This presentation aims to show some of the new GNU toolchains features for 2023. This year the Glibc project has added the capability to return high-quality randomness from the kernel through three new functions. At the same time, it has added a new function that allows a caller to release the memory of a dying process for better memory management of applications. The GCC compiler now has optimizations for five new x86 platforms, these optimizations enable ISA extensions for video codec, integer FMA, and Vector Neural Network Instructions based on INT8 among others. This presentation will show some examples in C code for developers to take advantage of these new ISA. GCC 13 will also have Address Sanitizer and Link-time optimization improvements. Having a better understanding of these innovations in toolchains allows developers to showcase the best of new platform architecture technology for users’ applications as well as boost the innovation and security of incoming projects.
