llvm/llvm-project has 8,218,225 source lines of code out of 11,420,548 total lines across 36,479 files, counted from the 6f6bbfb5e63e8cf4f051c7e5f773c41fe5ddbf19 ref at commit 6f6bbfb5e63e by the OctoCounts tokei engine on 2026-09-16. The report is cached by commit, tokei version, and analysis options, so recounting the same revision returns exactly these numbers.

OctoCounts produced this report by resolving llvm/llvm-project to commit 6f6bbfb5e63e, downloading the repository source archive, and counting every source file with tokei, the open-source line counter written in Rust. The table below breaks the count down by programming language into files, total lines, code lines, comment lines, and blank lines, so the figures can be compared across languages and projects. Results are cached by commit, tokei version, and analysis options, so counting the same revision again reproduces exactly these numbers.
