Toolchain
Toolchains continue to evolve as new SoC features are added. Speed and space optimisations are increasingly important, especially in the IoT space. New security features need compiler and tool support.
The world is rapidly changing, and as a result the open software on computing systems is having to accommodate a shift to greater use of machine learning, increasing mobile CPU performance. Linaro has provided open source tools for Arm architectures since its inception in 2010, working directly with upstream communities such as GCC, Binutils, GDB, Glibc, Newlib, LLVM, Clang, LLD, LLDB, QEMU, Valgrind and OpenOCD. Our mission is to improve and maintain open-source Arm toolchain projects.
We work on all aspects of system-level tools - the core development toolchain (compiler, assembler, linker, debugger), core system libraries (dynamic linker, c-library), and emulation.Linaro builds and tests LLVM community integration releases for ARM and AArch64 architectures (http://releases.llvm.org/download.html). Linaro maintainers serve as release managers for QEMU and Glibc project.
Linaro Projects focused on Toolchain technology
Arm GNU Toolchain Enablement and CI
The GNU Compiler Collection (GCC) is a compiler system produced by the GNU Project. It supports various programming languages and is a key component of the GNU toolchain. It is the the standard compiler for most projects related to GNU and Linux, including the Linux kernel. This Linaro project focuses on improving optimizations for popular Arm cores, supporting compiler sanitizers, supporting new Armv8 architectural features and improving the debugging experience.

LLVM is one of the main tools the open-source community uses to compile their code. It is a set of reusable compiler and toolchain technologies which are used to develop front ends for any programming language and back ends of any instruction set architecture. LLDB is the debugger component of the LLVM project. The Linaro toolchain team actively maintains the LLDB project and has ownership of Arm and AArch64 target specific code base. We implement new and improve existing code-size and code-speed optimizations for AArch64 and Arm targets.
