| ## Incremental ThinLTO with `b_thinlto_cache` | |
| [Incremental ThinLTO](https://clang.llvm.org/docs/ThinLTO.html#incremental) can now be enabled by passing | |
| `-Db_thinlto_cache=true` during setup. The use of caching speeds up incremental builds significantly while retaining all | |
| the runtime performance benefits of ThinLTO. | |
| The cache location defaults to a Meson-managed directory inside the build folder, but can be customized with | |
| `b_thinlto_cache_dir`. |
