Releases ยท llvm/llvm-project
Each platform has one binary release package. The file name starts with either LLVM- or clang+llvm- and ends with the platform's name. For example, LLVM-22.1.7-Linux-ARM64.tar.xz contains LLVM binaries for Arm64 Linux. Except for Windows. Where LLVM-*.exe is an installer intended for using LLVM as a toolchain and the archive clang+llvm- contains the contents of the installer, plus libraries and tools not normally used in a toolchain.
