Always record reference to binding in match if guards When encountering a binding from a `match` pattern in its `if` guard when computing a generator's interior types, we must always record the type of a reference to the binding because of how `if` guards are lowered to MIR. This was missed in #75213 because the binding in that test case was autorefed and we recorded that adjusted type anyway. Fixes #78366

[resolve] Use `unwrap_or_else` instead of `unwrap_or` in a hot path This improves the performance of the `resolve_crate` function by 30% for a very large single file crate with auto-generated C bindings. cc `@rylev`

Update Clippy - temporary_cstring_as_ptr deprecation In #75671 `clippy::temporary_cstr_as_ptr` was removed instead of being deprecated. This will trigger an error (unknown lint) for users that refer to that lint to e.g. allow it, instead of a more informative warning. This update should fix that for nightly users. r? @oli-obk

Prevent String::retain from creating non-utf8 strings when abusing panic Fixes #78498 The idea is the same as `Vec::drain`, set the len to 0 so that nobody can observe the broken invariant if it escapes the function (in this case if `f` panics)

Use unwrapDIPtr because the Scope may be null. I ran into an assertion when using debug information on Windows with LLVM assertions enabled. It seems like we are using unwrap here (which in turn calls isa and requires the pointer to be non-null) but we expect the value to be null because that is what we are passing from rustc. This change uses unwrapDIPtr which explicitly allows nullptr. The FFI prototype for this method on the rust side has the `LLVMMetadataRef` parameter as `Scope: Option<&'a DIScope>`, and we always pass `None` when `msvc_like_names` is true.

rustc_span: improve bounds checks in byte_pos_to_line_and_col The effect of this change is to consider edge-case spans that start or end at the position one past the end of a file to be valid during span hashing and encoding. This change means that these spans will be preserved across incremental compilation sessions when they are part of a serialized query result, instead of causing the dummy span to be used.

Dogfood {exclusive,half-open} ranges in compiler (nfc) In particular, this allows us to write more explicit matches that avoid the pitfalls of using a fully general fall-through case, yet remain fairly ergonomic. Less logic is in guard cases, more is in the actual exhaustive case analysis. No functional changes.

Improve documentation for slice strip_* functions Prompted by the stabilisation tracking issue #73413 I looked at the docs for `strip_prefix` and `strip_suffix` for both `str` and `slice`, and I felt they could be slightly improved. Thanks for your attention.

Include non-rustup artifacts in the manifest This PR fixes https://github.com/rust-lang/promote-release/issues/22 by including all the files we ship in the generated manifests, even the ones that are not installable through rustup. In practice this adds the following "artifacts": * `source-code`: the tarball containing the full source code used to build the release (`rustc-{channel}-src.tar.xz`) * `installer-msi`: the MSI installer for Windows systems (`rust-{channel}-{target}.msi`) * `installer-pkg`: the PKG installer for macOS systems (`rust-{channel}-{target}.pkg`) These files are included in a new `artifacts` table of the manifest, like so: ```toml [[artifacts.installer-msi.target.aarch64-pc-windows-msvc]] url = "https://example.com/2020-10-28/rust-nightly-aarch64-pc-windows-msvc.msi" hash-sha256 = "6b41d5b829d20834c5d93628d008ec618f8914ee79303363bd13a86fd5f305dd" [[artifacts.installer-msi.target.i686-pc-windows-gnu]] url = "https://example.com/2020-10-28/rust-nightly-i686-pc-windows-gnu.msi" hash-sha256 = "83f020de6e180c155add9fce1cea2ac6e5f744edbd6dc1581e24de8f56b2ca7a" [[artifacts.installer-msi.target.i686-pc-windows-msvc]] url = "https://example.com/2020-10-28/rust-nightly-i686-pc-windows-msvc.msi" hash-sha256 = "dbc80c24e9d5df01616c6f216114b4351f51a94218e2368b5cebe4165b270702" [[artifacts.installer-msi.target.x86_64-pc-windows-gnu]] url = "https://example.com/2020-10-28/rust-nightly-x86_64-pc-windows-gnu.msi" hash-sha256 = "8196eca3f02d72d4c8776ad4fcc72897125e2cf6404ae933e31c07e197e3c9fa" [[artifacts.installer-msi.target.x86_64-pc-windows-msvc]] url = "https://example.com/2020-10-28/rust-nightly-x86_64-pc-windows-msvc.msi" hash-sha256 = "b2e7fd6463790732fcf9c726b9448068712341943199cb40fc11d1138b8a207b" [[artifacts.installer-pkg.target.aarch64-apple-darwin]] url = "https://example.com/2020-10-28/rust-nightly-aarch64-apple-darwin.pkg" hash-sha256 = "70421c191752fb33886f8033b029e634bcc993b72308cef52a38405840e91f5c" [[artifacts.installer-pkg.target.x86_64-apple-darwin]] url = "https://example.com/2020-10-28/rust-nightly-x86_64-apple-darwin.pkg" hash-sha256 = "ebd7a5acb61e82d85e855146cc9bd856f32228ee7f40dd94c659b00614ed4f1f" [[artifacts.source-code.target."*"]] url = "https://example.com/2020-10-28/rustc-nightly-src.tar.gz" hash-sha256 = "5fcc487ee4c15c689de8ddf7daac7ff6a65c80498197b9aea58622dc2b3bca10" [[artifacts.source-code.target."*"]] url = "https://example.com/2020-10-28/rustc-nightly-src.tar.xz" hash-sha256 = "0c618ef0ec5f64da1801e9d0df6c755f6ed1a8780ec5c8ee75e55614be51d42c" ``` Each artifact can be available for multiple targets, and each target can have multiple versions of the same file (for example, a `gz`-compressed one and a `xz`-compressed one). In the future rustup might add functionality to let users retrieve the artifacts, but that's not needed to land this PR, and whether to do the implementation is up to the rustup maintainers. r? `@kinnison` cc `@Mark-Simulacrum`

rustdoc options to set default theme (and other settings) Hi. This is the MR I promised in #77024 It is a little more general than I envisaged there. Once I had found the settings-handling machinery it seemed foolish to add this feature just for the theme. Closes #77024

Clarify main code paths in exhaustiveness checking This PR massively clarifies the main code paths of exhaustiveness checking, by using the `Constructor` enum to a fuller extent. I've been itching to write it for more than a year, but the complexity of matching consts had prevented me. Behold a massive simplification :D. This in particular removes a fair amount of duplication between various parts, localizes code into methods of relevant types when applicable, makes some implicit assumptions explicit, and overall improves legibility a lot (or so I hope). Additionally, after my changes undoing #76918 turned out to be a noticeable perf gain. As usual I tried my best to make the commits self-contained and easy to follow. I've also tried to keep the code well-commented, but I tend to forget how complex this file is; I'm happy to clarify things as needed. My measurements show good perf improvements on the two match-heavy benchmarks (-18.0% on `unicode_normalization-check`! :D); I'd like a perf run to check the overall impact. r? `@varkor` `@rustbot` modify labels: +A-exhaustiveness-checking
