About LLVM
The LLVM Project is a set of modular, reusable compiler and toolchain components. It began as a research project at the University of Illinois aimed at an SSA-based compilation strategy for both static and dynamic compilation, and today includes the Clang C and C++ compiler along with linkers, debuggers and analysis tools such as scan-build and llvm-cov.
Releases are frequent, with version 23.1.2 published in September 2026, and binaries are offered for download along with APT and RPM packages and snapshots.
