Let us appreciate the dedication of the developer behind this repository, John Hodge. The first commit happened in November 2014. The repository now has 4287 commits, most of which are his. And now, this compiler fully bootstraps rustc on x86-64 Linux. I think that is really impressive and it’s also motivational for myself, to keep going with my (much smaller and less significant) projects.
The new constant evaluator is here. It’s quite interesting.
