We currently compiled bools to i8 values, because there was a bug in LLVM that sometimes caused miscompilations when using i1 in, for example, structs. Using i8 means a lot of unnecessary zero-extend and truncate operations though, since we have to convert the value from and to i1 when using for example icmp or br instructions. Besides the unnecessary overhead caused by this, it also sometimes made LLVM miss some optimizations. Fixes #8106.

To fix #8106, we need an LLVM version that contains r211082 aka 0dee6756 which fixes a bug that blocks that issue. There have been some tiny API changes in LLVM, and cmpxchg changed its return type. The i1 part of the new return type is only interesting when using the new weak cmpxchg, which we don't do.

When calling a foreign function, some arguments and/or return value attributes are required to conform to the foreign ABI. Currently those attributes are only added to the declaration of foreign functions. With direct calls, this is no problem, because LLVM can see that those attributes apply to the call. But with an indirect call, LLVM cannot do that and the attribute is missing. To fix that, we have to add those attribute to the calls to foreign functions as well. This also allows to remove the special handling of the SRet attribute, which is ABI-dependent and will be set via the `attr` field of the return type's `ArgType`.

The ArgType type gives us a generic way to specify an attribute for a type to ensure ABI conformance for foreign functions. But the code that actually sets the argument attributes in the function declaration only sets the attribute for the return type when the type is indirect. Since LLVMAddAttribute() doesn't allow to set attributes on the return type, we have to use LLVMAddFunctionAttribute() instead. This didn't cause problems yet, because currently only some indirect types require attributes to be set.

This commit makes several changes to the stability index infrastructure: * Stability levels are now inherited lexically, i.e., each item's stability level becomes the default for any nested items. * The computed stability level for an item is stored as part of the metadata. When using an item from an external crate, this data is looked up and cached. * The stability lint works from the computed stability level, rather than manual stability attribute annotations. However, the lint still checks only a limited set of item uses (e.g., it does not check every component of a path on import). This will be addressed in a later PR, as part of issue #8962. * The stability lint only applies to items originating from external crates, since the stability index is intended as a promise to downstream crates. * The "experimental" lint is now _allow_ by default. This is because almost all existing crates have been marked "experimental", pending library stabilization. With inheritance in place, this would generate a massive explosion of warnings for every Rust program. The lint should be changed back to deny-by-default after library stabilization is complete. * The "deprecated" lint still warns by default. The net result: we can begin tracking stability index for the standard libraries as we stabilize, without impacting most clients. Closes #13540.

This PR is changing the error messages for non-exhaustive pattern matching to include a more accurate witness, i.e. a pattern that is not covered by any of the ones provided by the user. Example: ```rust fn main() { match (true, (Some("foo"), [true, true]), Some(42u)) { (false, _, _) => (), (true, (None, [true, _]), None) => (), (true, (None, [false, _]), Some(1u)) => () } } ``` ```sh /tmp/witness.rs:2:2: 6:3 error: non-exhaustive patterns: (true, (core::option::Some(_), _), _) not covered /tmp/witness.rs:2 match (true, (Some("foo"), [true, true]), Some(42u)) { /tmp/witness.rs:3 (false, _, _) => (), /tmp/witness.rs:4 (true, (None, [true, _]), None) => (), /tmp/witness.rs:5 (true, (None, [false, _]), Some(1u)) => () /tmp/witness.rs:6 } ``` As part of that, I refactored some of the relevant code and carried over the changes to fixed vectors from the previous PR. I'm putting it out there for now but the tests will be red.

Closes #8142. This is not the semantics we want long-term. You can continue to use `#[unsafe_destructor]`, but you'll need to add `#![feature(unsafe_destructor)]` to the crate attributes. [breaking-change] r? @alexcrichton

The struct and module doc comments are reformulated. The `execute` method's documentation are put up to date, and failure information is added. A test is also added to address the possible failure.

```test_harness #[test] fn foo() {} ``` will now compile and run the tests, rather than just ignoring & stripping them (i.e. it is as if `--test` was passed). Also, the specific example in https://github.com/rust-lang/rust/issues/12242 was fixed (but that issue is broader than that example).

rustdoc now supports compiling things with `--test` so the examples in this guide can be compiled & tested properly (revealing a few issues & out-dated behaviours). Also, reword an example to be clearer, cc #12242.

Continuing from #15012, this makes four changes to the `rustdoc` static files. - Change the placeholder text of the search bar to `Click or press 'S' to search, '?' for more options...` to make keyboard hotkeys more apparent (capitalizing the `S` to match the help text). - Change the `main.js` file to use browser-normalized key codes (`e.which`, from `jQuery`), instead of `e.keyCode`. - Change the key code for `?` to be the correct `191` instead of `188`, so that the hotkey works to bring up search information. - Change the search information to display `tab` and `shift+tab` instead of `up` and `down`, as those do not yet work outside of Firefox (see #15011). Also, adjust the height so it does not cut off the help text. <s>I've also opened up #15038 about the non-functional `up` and `down` functionality, although this does nothing to fix it.</s>

This adds the `test_harness` directive that runs a code block using the test runner, to allow for `#[test]` items to be demonstrated and still tested (currently they are just stripped and not even compiled, let alone run).
