2020-12-03Coverage tests for remaining TerminatorKinds and async, improve AssertRich Kadel-3/+1
Tested and validate results for panic unwind, panic abort, assert!() macro, TerminatorKind::Assert (for example, numeric overflow), and async/await. Implemented a previous documented idea to change Assert handling to be the same as FalseUnwind and Goto, so it doesn't get its own BasicCoverageBlock anymore. This changed a couple of coverage regions, but I validated those changes are not any worse than the prior results, and probably help assure some consistency (even if some people might disagree with how the code region is consistently computed). Fixed issue with async/await. AggregateKind::Generator needs to be handled like AggregateKind::Closure; coverage span for the outer async function should not "cover" the async body, which is actually executed in a separate "closure" MIR.

Add wasm32 support to inline asm There is some contention around inline asm and wasm, and I really only made this to figure out the process of hacking on rustc, but I figured as long as the code existed, it was worth uploading. cc `@Amanieu`

Update with status for various NetBSD ports. The NetBSD ports of rust to aarch64, armv7*, i686, and powerpc** all both build and run. Status is as of rust 1.47.0. *) Natively requires repeated successive build attempts (`rustc` is such a resource pig VM-consumption-wise), or run in a chroot on an aarch64 host where the available VM space is 4GB instead of the native 2GB. **) Powerpc either requires `-latomic` in a directory searched by default by `ld` or to be built within pkgsrc which has a patch and support package to tackle this issue.

2020-11-30Improve contributor experience for the dev-guide itself (#973)Joshua Nelson-57/+14
- Fix typos in the README - Don't echo all instructions in the linkcheck.sh shellscript; this is noisy and unhelpful when developing locally. Verbose output is still enabled in CI. - Link to the index page for compiler docs, not `rustc_middle`. Note that the compiler docs are not a guide - that's us! - Remove outdated instructions about avoiding 429s. These should no longer be occurring locally now that we're using caching. - Consolidate info about `mdbook` and `mdbook-linkcheck` near each other

2020-11-25Auto merge of #79336 - camelid:rename-feature-oibit-to-auto, r=oli-obkbors-3/+3
Rename `optin_builtin_traits` to `auto_traits` They were originally called "opt-in, built-in traits" (OIBITs), but people realized that the name was too confusing and a mouthful, and so they were renamed to just "auto traits". The feature flag's name wasn't updated, though, so that's what this PR does. There are some other spots in the compiler that still refer to OIBITs, but I don't think changing those now is worth it since they are internal and not particularly relevant to this PR. Also see <https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/opt-in.2C.20built-in.20traits.20(auto.20traits).20feature.20name>. r? `@oli-obk` (feel free to re-assign if you're not the right reviewer for this)

2020-11-16Rollup merge of #78714 - m-ou-se:simplify-local-streams, r=KodrAusMara Bos-6/+1
Simplify output capturing This is a sequence of incremental improvements to the unstable/internal `set_panic` and `set_print` mechanism used by the `test` crate: 1. Remove the `LocalOutput` trait and use `Arc<Mutex<dyn Write>>` instead of `Box<dyn LocalOutput>`. In practice, all implementations of `LocalOutput` were just `Arc<Mutex<..>>`. This simplifies some logic and removes all custom `Sink` implementations such as `library/test/src/helpers/sink.rs`. Also removes a layer of indirection, as the outermost `Box` is now gone. It also means that locking now happens per `write_fmt`, not per individual `write` within. (So `"{} {}\n"` now results in one `lock()`, not four or more.) 2. Since in all cases the `dyn Write`s were just `Vec<u8>`s, replace the type with `Arc<Mutex<Vec<u8>>>`. This simplifies things more, as error handling and flushing can be removed now. This also removes the hack needed in the default panic handler to make this work with `::realstd`, as (unlike `Write`) `Vec<u8>` is from `alloc`, not `std`. 3. Replace the `RefCell`s by regular `Cell`s. The `RefCell`s were mostly used as `mem::replace(&mut *cell.borrow_mut(), something)`, which is just `Cell::replace`. This removes an unecessary bookkeeping and makes the code a bit easier to read. 4. Merge `set_panic` and `set_print` into a single `set_output_capture`. Neither the test crate nor rustc (the only users of this feature) have a use for using these separately. Merging them simplifies things even more. This uses a new function name and feature name, to make it clearer this is internal and not supposed to be used by other crates. Might be easier to review per commit.
