2020-12-23Auto merge of #80099 - jyn514:visibility-on-demand, r=GuillaumeGomezbors-60/+70
Remove `DefPath` from `Visibility` and calculate it on demand Depends on #80090 and should not be merged before. Helps with https://github.com/rust-lang/rust/issues/79103 and https://github.com/rust-lang/rust/issues/76382. cc https://github.com/rust-lang/rust/pull/80014#issuecomment-746810284 - `@nnethercote` I figured it out! It was simpler than I expected :) This brings the size of `clean::Visibility` down from 40 bytes to 8. Note that this does *not* remove `clean::Visibility`, even though it's now basically the same as `ty::Visibility`, because the `Invsible` variant means something different from `Inherited` and I thought it would be be confusing to merge the two. See the new comments on `impl Clean for ty::Visibility` for details.
2020-12-23Auto merge of #80095 - jyn514:stability-on-demand, r=GuillaumeGomezbors-80/+75
[rustdoc] Calculate stability, const_stability, and deprecation on-demand Previously, they would always be calculated ahead of time, which bloated the size of `clean::Item`. Builds on https://github.com/rust-lang/rust/pull/80090 and should not be merged before. Helps with https://github.com/rust-lang/rust/issues/79103 and https://github.com/rust-lang/rust/issues/76382. cc https://github.com/rust-lang/rust/pull/80014#issuecomment-746810284 This brings `Item` down to 568 bytes, down from 616.

Remove `I-prioritize` from Zulip topic It doesn't add anything since every topic in `t-compiler/wg-prioritization/alerts` is about prioritization. And it makes it harder to see the issue title, which is what the topic is actually about. cc ``@rust-lang/wg-prioritization``

Add test for issue #74824 It was fixed a while ago, but doesn't have a test. Closes #74824
2020-12-22Auto merge of #80242 - Nadrieril:explain-and-factor-splitting, r=varkorbors-787/+895
Clarify constructor splitting in exhaustiveness checking I reworked the explanation of the algorithm completely to make it properly account for the various extensions we've added. This includes constructor splitting, which was previously not clearly included in the algorithm. This makes wildcards less magical; I added some detailed examples; and this distinguishes clearly between constructors that only make sense in patterns (like ranges) and those that make sense for values (like `Some`). This reformulation had been floating around in my mind for a while, and I'm quite happy with how it turned out. Let me know how you feel about it. I also factored out all three cases of splitting (wildcards, ranges and slices) into dedicated structs to encapsulate the complicated bits. I measured no perf impact but I don't trust my local measurements for refactors since https://github.com/rust-lang/rust/pull/79284. r? `@varkor` `@rustbot` modify labels: +A-exhaustiveness-checking
2020-12-22Auto merge of #80177 - tgnottingham:foreign_defpathhash_registration, ↵bors-63/+54
r=Aaron1011 rustc_query_system: explicitly register reused dep nodes Register nodes that we've reused from the previous session explicitly with `OnDiskCache`. Previously, we relied on this happening as a side effect of accessing the nodes in the `PreviousDepGraph`. For the sake of performance and avoiding unintended side effects, register explictily.

2020-12-22Auto merge of #79451 - usbalbin:array_zip, r=m-ou-sebors-0/+31
Added [T; N]::zip() This is my first PR to rust so I hope I have done everything right, or at least close :) --- This is PR adds the array method `[T; N]::zip()` which, in my mind, is a natural extension to #75212. My implementation of `zip()` is mostly just a modified copy-paste of `map()`. Should I keep the comments? Also am I right in assuming there should be no way for the `for`-loop to panic, thus no need for the dropguard seen in the `map()`-function? The doc comment is in a similar way a slightly modified copy paste of [`Iterator::zip()`](https://doc.rust-lang.org/beta/std/iter/trait.Iterator.html#method.zip) `@jplatte` mentioned in [#75490](https://github.com/rust-lang/rust/pull/75490#issuecomment-677790758) `zip_with()`, > zip and zip_with seem like they would be useful :) is this something I should add (assuming there is interest for this PR at all :))
