A guide to how rustc works and how to contribute to it.
@JakobDegen has very kindly written up a summary of how dataflow works: https://hackmd.io/@2S4Crel_Q9OwC_vamlwXmw/ryqfn_vZn Unlike the existing chapter (https://rustc-dev-guide.rust-lang.org/mir/dataflow.html#dataflow-analysis), this is a *conceptual* background, not a guide to how to write...
This is covered in the new chapter on fuzzing, but bug minimization is a cross-cutting concern that deserves its own page. Should describe both manual techniques and automated tools. Related...

This PR adds some (very conservative) documentation for a new compiletest directive regarding check-cfg; as well as documentation regarding the use of the `FALSE` cfg as convention for an always-false...

We discussed today [on Zulip](https://rust-lang.zulipchat.com/#narrow/stream/122651-general/topic/I'd.20like.20to.20contribute.20more.20.28to.20Apple-specific.20stuff.29/near/434259421) that it would be nice with some documentation on this ping group. Additionally, I've tried to document a few of the common challenges that we...
