## Health v2 (maintenance only)
Score: 10/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 5332, "days_push": 2191, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, archived, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
LLVM is a modular compiler infrastructure providing an SSA-based intermediate representation, a source- and target-independent optimizer, and retargetable code generation for many CPU architectures, plus JIT compilation support. This particular repository is the legacy llvm-mirror on GitHub, which has moved to the unified llvm/llvm-project repository.

## Use cases
- build a compiler backend for a new programming language
- generate optimized machine code for multiple CPU architectures
- implement a JIT compiler for a scripting language
- optimize and transform code at link time
- learn how compilers work with the Kaleidoscope tutorial
- compile LLVM IR to native object code

## When to choose
- you are building a language frontend, optimizer, or code generator and need a mature, production-proven compiler toolkit
- you need retargetable code generation across many architectures
- you want JIT or ahead-of-time compilation from a common IR

## When to avoid
- you want the actively developed source - use llvm/llvm-project instead of this archived mirror
- you need a simple high-level compiler without deep systems expertise
- you expect quick builds or small binaries - LLVM is large and slow to compile

## Facets
- artifact type: library
- maturity: abandoned
- function: compiler, interpreter, developer-tools
- domain: compilers, programming-languages, developer-tools, performance
- platform: cross-platform, cpp, windows
- tags: llvm, llvm-ir, code-generation, jit, optimizer, compiler-infrastructure, mirror-repo, moved, linux, macos
