The linked llvm article about performance ( https://nikic.github.io/2020/05/10/Make-LLVM-fast-again.html https://nikic.github.io/2020/05/10/Make-LLVM-fast-again.html ) says:
"Rust does this by running a set of benchmarks on every merge, with the data available on perf.rust-lang.org. Additionally, it is possible to run benchmarks against pull requests using the @rust-timer bot. This helps evaluate changes that are intended to improve compile-time performance, or are suspected of having non-trivial compile-time cost."
So, they do seem to have a bot to perform such tests, though I have no clue how often they use it.
