This was added to in 2019 to speed up rebuild times when LLVM was
modified. Now that download-ci-llvm exists, I don't think it makes sense
to support an unsound option like this that can lead to miscompiles; and
the code cleanup is nice too.
Do some cleanup of doc/index.md
I think a lot of people get to this landing page from `rustup doc`, and it's a bit tricky to find some useful information. I attempted to clean it up here a bit, from the commit message:
- Add quick link to API docs
- Add marker for external links, to help offline users
- Add information about using 'cargo doc' and the playground
- Clean up some of the wording
- Update body & header style to match rustdoc defaults
- Bump heading levels so main page header is 1, others are 2 (all were level 1 before)
Update `fuchsia-test-runner.py` and docs
This updates the test runner to the latest version of the SDK and fixes debugging support for Rust source code.

Add `kernel-address` sanitizer support for freestanding targets
This PR adds support for KASan (kernel address sanitizer) instrumentation in freestanding targets. I included the minimal set of `x86_64-unknown-none`, `riscv64{imac, gc}-unknown-none-elf`, and `aarch64-unknown-none` but there's likely other targets it can be added to. (`linux_kernel_base.rs`?) KASan uses the address sanitizer attributes but has the `CompileKernel` parameter set to `true` in the pass creation.
Most tests involving save-analysis were removed, but I kept a few where
the `-Zsave-analysis` was an add-on to the main thing being tested,
rather than the main thing being tested.
For `x.py install`, the `rust-analysis` target has been removed.
For `x.py dist`, the `rust-analysis` target has been kept in a
degenerate form: it just produces a single file `reduced.json`
indicating that save-analysis has been removed. This is necessary for
rustup to keep working.
Closes#43606.
Update broken link in cargo style guide
Toml now uses [toml.io](https://toml.io) for released specifications and the github repo for development. Also the old link was for the 0.4 specification, while cargo uses toml_edit, which uses toml 1.0 (reference:
https://github.com/toml-rs/toml/blob/main/crates/toml_edit/CHANGELOG.md#030---2021-09-13). Finally the discussion of "Bare keys" vs "Quoted keys" has moved from the `#table` section to `#keys`.
Recognize all bells and whistles that LLVM's XRay pass is capable of.
The always/never settings are a bit dumb without attributes but they're
still there. The default instruction count is chosen by the compiler,
not LLVM pass. We'll do it later.
- Remove logic that limits const eval based on terminators, and use the
stable metric instead (back edges + fn calls)
- Add unstable flag `tiny-const-eval-limit` to add UI tests that do not
have to go up to the regular 2M step limit

Because the old spelling is widely used, some projects may need time to
migrate their uses to the new triple spelling. The old spelling may
eventually be removed altogether.
Historically, Rust's Fuchsia targets have been labeled x86_64-fuchsia
and aarch64-fuchsia. However, they should technically contain vendor
information. This CL changes Fuchsia's target triples to include the
"unknown" vendor since Clang now does normalization and handles all
triple spellings.
This was previously attempted in #90510, which was closed due to
inactivity.
Update Fuchsia walkthrough with new configs
The new `download-ci-llvm` configuration option dosn't work with `lld = true` (see #100853). The Fuchsia walkthrough should recommend setting it to `false`.
r? `@tmandry`
The new `download-ci-llvm` configuration option dosn't work with `lld =
true` (see #100853). The Fuchsia walkthrough should recommend setting it
to `false`.
This allows analyzing the output programatically; for example, finding
the item with the highest `total_estimate`.
I also took the liberty of adding `untracked` tests to `rustc_session` and documentation to the unstable book for `dump-mono-items`.
