2020-10-14Rollup merge of #77829 - gburgessiv:unused-features-var, r=alexcrichtonDylan DPC-5/+5
bootstrap: only use compiler-builtins-c if they exist The assignment of `features` above was added in rust-lang#60981, but never used. Presumably the intent was to replace the string literal here with it. While I'm in the area, `compiler_builtins_c_feature` doesn't need to be a `String`. I'm not entirely sure of a great way to locally test this -- `./x.py test` passed on my machine, but 🤷‍♂️. r? @alexcrichton
2020-10-14Rollup merge of #77817 - jyn514:const-since, r=petrochenkovDylan DPC-81/+61
Switch rustdoc from `clean::Stability` to `rustc_attr::Stability` This gives greater type safety and is less work to maintain on the rustdoc end. It also makes rustdoc more consistent with rustc. Noticed this while working on https://github.com/rust-lang/rust/issues/76998. - Remove `clean::Stability` in favor of `rustc_attr::Stability` - Remove `impl Clean for Stability`; it's no longer necessary r? @GuillaumeGomez cc @petrochenkov
2020-10-14Rollup merge of #77795 - bjorn3:codegen_backend_interface_refactor, r=oli-obkDylan DPC-32/+26
Codegen backend interface refactor This moves several things away from the codegen backend to rustc_interface. There are a few behavioral changes where previously the incremental cache (incorrectly) wouldn't get finalized, but now it does. See the individual commit messages.

2020-10-14Auto merge of #77135 - Aaron1011:pretty-ignore-paren, r=petrochenkovbors-0/+220
Refactor AST pretty-printing to allow skipping insertion of extra parens Fixes #75734 Makes progress towards #43081 Unblocks PR #76130 When pretty-printing an AST node, we may insert additional parenthesis to ensure that precedence is properly preserved in code we output. However, the proc macro implementation relies on comparing a pretty-printed AST node to the captured `TokenStream`. Inserting extra parenthesis changes the structure of the reparsed `TokenStream`, making the comparison fail. This PR refactors the AST pretty-printing code to allow skipping the insertion of additional parenthesis. Several freestanding methods are moved to trait methods on `PrintState`, which keep track of an internal `insert_extra_parens` flag. This flag is normally `true`, but we expose a public method which allows pretty-printing a nonterminal with `insert_extra_parens = false`. To avoid changing the public interface of `rustc_ast_pretty`, the freestanding `_to_string` methods are changed to delegate to a newly-crated `State`. The main pretty-printing code is moved to a new `state` module to ensure that it does not accidentally call any of these public helper functions (instead, the internal functions with the same name should be used).

`min_const_generics` diagnostics improvements As disscussed in [zulip/project-const-generics/non-trivial anonymous constant](https://rust-lang.zulipchat.com/#narrow/stream/260443-project-const-generics/topic/non-trivial.20anonymous.20constants).

Mention rustdoc in `x.py setup` This lets new contributors know which option they should pick; previously it wasn't clear 'compiler' also included rustdoc. Unresolved questions: should this say 'compiler and tools' instead? I don't know of any tools that are modified in-tree other than rustdoc, though. r? @Mark-Simulacrum

2020-10-13Auto merge of #77762 - pietroalbini:dist-build-manifest, r=Mark-Simulacrumbors-56/+126
Dist build manifest This PR makes two changes that should remove a significant chunk of the time spent in our release process: cloning the `rust-lang/rust` monorepo, all its submodules, and building `bootstrap` to then invoke `build-manifest`: * `build-manifest` doesn't rely on a clone of the monorepo being present anymore. The only remaining bit of information it fetched from it (the Rust version) is instead bundled in the binary. * A new "component" is added, `build-manifest`. That component includes a prebuilt version of the tool, and it's *not* included in the Rustup manifest. This will allow `promote-release` to directly invoke the tool without interacting with our build system. * The Linux x86_64 CI is changed to also build the component mentioned above. It's the only CI builder tasked to do so, and to cleanly support this a new `--include-default-paths` flag was added to `./x.py`. * The `BUILD_MANIFEST_NUM_THREADS` environment variable is added to configure the number of threads at runtime. This PR is best reviewed commit-by-commit. r? `@Mark-Simulacrum`

rustdoc: skip #[allow(missing docs)] for docs in coverage report During the document coverage reporting with: ```bash rustdoc something.rs -Z unstable-options --show-coverage ``` the coverage report counts code that is marked with `#[allow(missing_docs)]` for the calculation, which outputs lower numbers in the coverage report even though these parts should be ignored for the calculation. Right now I'm not sure how this can be tested (CI)? (I verified it by hand and ran the unit tests) r? `@jyn514` **Reference:** Fixes #76121

2020-10-12build-manifest: accept the Rust version instead of the monorepo pathPietro Albini-16/+9
This commit changes the way build-manifest is invoked, to let it accept the Rust version directly instead of requiring the path of the Rust monorepo and letting build-manifest figure out the path on its own. This allows to run build-manifest without a clone of the monorepo.
