| # Optimized build pipeline | |
| This binary implements a heavily optimized build pipeline for `rustc` and `LLVM` artifacts that are used for both for | |
| benchmarking using the perf. bot and for final distribution to users. | |
| It uses LTO, PGO and BOLT to optimize the compiler and LLVM as much as possible. | |
| This logic is not part of bootstrap, because it needs to invoke bootstrap multiple times, force-rebuild various | |
| artifacts repeatedly and sometimes go around bootstrap's cache mechanism. |
