EuroLLVM is an annual European gathering focused on the LLVM compiler infrastructure and surrounding ecosystem. The event brings together developers, researchers, and industry representatives associated with projects such as Clang (compiler), Rust (programming language), and Swift (programming language), facilitating exchange among contributors from organizations like Google, Apple Inc., and Mozilla. EuroLLVM operates alongside broader forums such as LLVM Developers' Meeting and interfaces with standards and research bodies including ISO/IEC JTC 1 and academic conferences like PLDI and CGO.

History

EuroLLVM began in the early 2010s, emerging from informal meetups among contributors to LLVM and Clang (compiler) in Europe. Early editions featured talks by members from Apple Inc., ARM Holdings, and academic groups from institutions such as ETH Zurich and University of Cambridge. Over time, the conference expanded its program to reflect advances in projects like MLIR and languages interoperating with LLVM backends such as Swift (programming language) and Rust (programming language). Major milestones include sessions on integration with CUDA toolchains, demonstrations tied to Embedded World and collaborations with compiler toolchains from GCC contributors.

Organization and Governance

EuroLLVM is organized by volunteer committees drawn from companies and institutions including Google, Intel Corporation, ARM Holdings, and research labs at University of Oxford and TU Delft. Program decisions are informed by submission review panels mirroring academic peer review practices used at conferences such as ICFP and SOSP. Sponsorship and venue logistics often involve partnerships with corporate entities like NVIDIA and research consortia associated with HPC centers and institutes such as CEA (French Alternative Energies and Atomic Energy Commission) and INRIA. The event follows policies compatible with the LLVM project's governance and the LLVM Foundation's bylaws.

Conference and Events

The annual EuroLLVM schedule typically includes keynotes, lightning talks, tutorials, and hackathons, drawing speakers with backgrounds at Apple Inc., Google, Mozilla, Microsoft, and academic labs such as University of Cambridge and ETH Zurich. Hands-on workshops often cover integrations with ecosystems like ARM toolchains, RISC-V toolchains, and GPU stacks from NVIDIA and AMD; tutorials mirror educational offerings at events like FOSDEM and CppCon. Parallel hackathons foster contributions to subprojects including LLDB, Compiler-RT, and libc++, while outreach tracks engage student chapters from universities including Imperial College London and RWTH Aachen University.

Topics and Activities

EuroLLVM addresses technical subjects such as backend code generation for architectures like x86 architecture, ARM architecture, and RISC-V, as well as intermediate representations like MLIR and LLVM IR. Sessions explore static analysis with tools related to Sanitizers, runtime support such as libc++, and language frontends including Clang (compiler), Rust (programming language), and Swift (programming language). Other activities include debugging and profiling strategies involving LLDB and perf (Linux), build-system integration with CMake and Bazel (software), and binary instrumentation techniques akin to work at Valgrind and DynamoRIO.

Participants and Community

Attendees span engineers from Google, Apple Inc., Intel Corporation, ARM Holdings, NVIDIA, AMD, researchers from ETH Zurich, University of Cambridge, KTH Royal Institute of Technology, and contributors from open-source foundations like the LLVM Foundation and Apache Software Foundation. The community includes maintainers of projects such as Clang (compiler), LLDB, libc++, Compiler-RT, and implementers of language runtimes for Rust (programming language) and Swift (programming language). Student contributors and academic presenters often come from programs at Imperial College London, TU Delft, and École Polytechnique.

Impact and Contributions

EuroLLVM has influenced roadmaps for projects like MLIR and enhancements to Clang AST and LLVM IR optimizations. Outcomes include improved cross-platform support involving Windows, Linux kernel use cases, and embedded toolchains for ARM and RISC-V ecosystems. Collaborative work at EuroLLVM has contributed patches and design proposals adopted in repositories under the LLVM Foundation and in toolchains used by corporations such as Google and Apple Inc.. The conference has also strengthened ties with standards organizations like ISO/IEC JTC 1 and led to research collaborations published in venues such as PLDI and OOPSLA.

Related Projects and Collaborations

EuroLLVM interacts with a range of projects and communities: upstream LLVM projects such as Clang (compiler), LLDB, libc++, and Compiler-RT; language ecosystems including Rust (programming language), Swift (programming language), and Go (programming language) backends; vendor toolchains from ARM Holdings, Intel Corporation, NVIDIA, and AMD; and academic collaborations with institutions like ETH Zurich, University of Cambridge, and RWTH Aachen University. The event aligns with other conferences and gatherings such as LLVM Developers' Meeting, FOSDEM, CppCon, and research conferences including PLDI and CGO.
