I think this is a worthy effort :-) I find the compile times of rust to be quite a big negative point. However: > For every tested commit, the programs are compiled in three different configurations: O3, ReleaseThinLTO and ReleaseLTO-g. All of these use -O3 in three different LTO configurations (none, thin and fat), with the last one also enabling debuginfo generation. I would have thought for developer productivity tracking -O1 compile times would be better wouldn't it? I'm happy for the CI to spend ages crunching out the best possible binary, but taking time out of the edit-compile-test loop would really help developers.
