It packages a stable 15.x generation of the LLVM compiler infrastructure for users and downstream builds that cannot simply follow the current llvm formula. ### Project history LLVM 15 continued the LLVM project's evolution from reusable optimizer and code-generation libraries into a broad compiler-toolchain platform. Like other major LLVM releases, it shipped coordinated updates across LLVM core, Clang, LLDB, LLD, libc++, compiler-rt, MLIR, and related developer tools. A defining migration point for LLVM 15 was opaque pointers. The official opaque-pointer documentation states that LLVM 15 enabled opaque pointers by default while typed pointers were still supported, making this release a compatibility hinge between older typed-pointer IR users and the LLVM 17 world where typed pointers were no longer supported. ### Adoption history The formula's versioned shape reflects how package ecosystems adopt LLVM: compiler stacks move quickly, but language runtimes, static analyzers, code generators, and editor tools often need one major line pinned until their LLVM API usage catches up. llvm@15 offered that stable target after the 15.0.0 release. The input metadata shows llvm@15 packaged under names such as llvm15, llvm-15, clangd, clang15, and Homebrew llvm@15 across Linux, macOS, Windows-oriented, and Nix-style ecosystems. That spread is typical for LLVM major releases because both command-line users and build dependencies need predictable versioned tools. ### How it is used Users install llvm@15 to get clang-15, LLVM 15 libraries and headers, LLVM binary utilities, LLDB/LLD tools where packaged, and helper tools such as clang-tidy, clang-format, clangd, llvm-config, opt, llc, and FileCheck. It is most useful when a build explicitly requires LLVM 15 or when maintainers need to test code against the opaque-pointer default before moving to later LLVM releases. ### Why package nerds care llvm@15 is significant because it packaged one of LLVM's biggest IR model transitions as a selectable toolchain rather than forcing every downstream package to migrate at once. That is exactly why package managers keep versioned compiler stacks around. For maintainers, llvm@15 often marks the point where old typed-pointer assumptions become visible in build logs and tests, while still leaving escape hatches unavailable in later releases. ### Timeline - 2000: LLVM begins as a University of Illinois compiler research project. - 2022-09-06: LLVM 15.0.0 is published on GitHub. - 2022-09-20: LLVM 15.0.1 is published. - 2022: LLVM 15 enables opaque pointers by default while retaining typed-pointer support. - 2023: Package ecosystems continue carrying llvm-15 packages while LLVM 16 and 17 advance the opaque-pointer transition. ### Related projects - LLVM 15 ships with Clang 15, LLDB 15, LLD 15, libc++, compiler-rt, MLIR, OpenMP, and related LLVM tools. - It is related to llvm@14 as the next migration step, and to llvm@16 and llvm@17 as later stages in the opaque-pointer transition. ### Sources - - - - - - source_facts.package-manager ## Security Notes No matching local secret-handling manifest was found for llvm@15.
