Introduction

Development of GNU Toolchain:

• GCC compiler

  • We improve SVE auto-vectorization optimizations and microarchitecture-specific optimizations for popular Arm cores.

  • We support compiler sanitizers (ASAN, TSAN, etc.) in GCC. Sanitizers are developed under the LLVM Toolchain project, and sanitizer changes are then merged into GCC to have both LLVM and GNU toolchains provide sanitizer features.

• GDB debugger

  • We develop support for the new ARMv9.x architectural features, help maintain the AArch32 and AArch64 targets and improve the debugging experience.

• Glibc C Library

  • We implement both target-specific and generic optimizations in Glibc. We then aim to propagate all relevant Glibc improvements to Newlib and Bionic C libraries.

  • We are improving the glibc support for LLVM toolchain, by adding support to glibc to be built with LLVM tools (clang, lld, etc.) to most important targets (aarch64, arm, x86) and focusing on keeping parity with GNU toolchain regarding support and regressions.

  • We also act as general maintainers, providing available patch reviews, and bug fixes, and help with general discussions.

• GNU Binutils assembler, BFD, and Gold linkers

  • In Binutils, we implement ELF section-level optimizations, as well as workarounds for hardware errata.
