2022-08-03Rollup merge of #100029 - hdelc:master, r=cjgillotMatthias Krüger-12/+36
Prevent ICE for `doc_alias` on match arm, statement, expression Fixes #99777. This is a pretty minimal fix that should be safe, since rustdoc doesn't generate documentation for match arms, statements, or expressions. I mentioned in the linked issue that the `doc_alias` target checking should probably be improved to avoid future ICEs, but as a new contributor, I'm not confident enough with the HIR types to make a larger change.

relate `closure_substs.parent_substs()` to parent fn in NLL Fixes #98589 The discrepancy between early- and late-bound lifetimes is because we map early-bound lifetimes into those found in the `closure_substs` while late-bound lifetimes are mapped into liberated free regions: https://github.com/rust-lang/rust/blob/5f98537eb7b5f42c246a52c550813c3cff336069/compiler/rustc_borrowck/src/universal_regions.rs#L255-L261 r? `@rust-lang/types`

fix is_disaligned logic for nested packed structs https://github.com/rust-lang/rust/pull/83605 broke the `is_disaligned` logic by bailing out of the loop in `is_within_packed` early. This PR fixes that problem and adds suitable tests. Fixes https://github.com/rust-lang/rust/issues/99838

2022-08-02Auto merge of #92268 - jswrenn:transmute, r=oli-obkbors-0/+4128
Initial implementation of transmutability trait. *T'was the night before Christmas and all through the codebase, not a miri was stirring — no hint of `unsafe`!* This PR provides an initial, **incomplete** implementation of *[MCP 411: Lang Item for Transmutability](https://github.com/rust-lang/compiler-team/issues/411)*. The `core::mem::BikeshedIntrinsicFrom` trait provided by this PR is implemented on-the-fly by the compiler for types `Src` and `Dst` when the bits of all possible values of type `Src` are safely reinterpretable as a value of type `Dst`. What this PR provides is: - [x] [support for transmutations involving primitives](https://github.com/jswrenn/rust/tree/transmute/src/test/ui/transmutability/primitives) - [x] [support for transmutations involving arrays](https://github.com/jswrenn/rust/tree/transmute/src/test/ui/transmutability/arrays) - [x] [support for transmutations involving structs](https://github.com/jswrenn/rust/tree/transmute/src/test/ui/transmutability/structs) - [x] [support for transmutations involving enums](https://github.com/jswrenn/rust/tree/transmute/src/test/ui/transmutability/enums) - [x] [support for transmutations involving unions](https://github.com/jswrenn/rust/tree/transmute/src/test/ui/transmutability/unions) - [x] [support for weaker validity checks](https://github.com/jswrenn/rust/blob/transmute/src/test/ui/transmutability/unions/should_permit_intersecting_if_validity_is_assumed.rs) (i.e., `Assume::VALIDITY`) - [x] visibility checking What isn't yet implemented: - [ ] transmutability options passed using the `Assume` struct - [ ] [support for references](https://github.com/jswrenn/rust/blob/transmute/src/test/ui/transmutability/references.rs) - [ ] smarter error messages These features will be implemented in future PRs.

2022-08-02Rollup merge of #99958 - PrestonFrom:issue_99907, r=compiler-errorsMatthias Krüger-104/+220
Improve position named arguments lint underline and formatting names For named arguments used as implicit position arguments, underline both the opening curly brace and either: * if there is formatting, the next character (which will either be the closing curl brace or the `:` denoting the start of formatting args) * if there is no formatting, the entire arg span (important if there is whitespace like `{ }`) This should make it more obvious where the named argument should be. Additionally, in the lint message, emit the formatting argument names without a dollar sign to avoid potentially confusion. Fixes #99907

RISC-V ASM test: relax label name constraint. The test is currently [broken at LLVM Head](https://buildkite.com/llvm-project/rust-llvm-integrate-prototype/builds/12425#01825d5b-c3d1-4fdc-a98d-5956b246aee2), likely since https://github.com/llvm/llvm-project/commit/260a64106854986a981e49ed87ee740460a23eb5: ```plain /var/lib/buildkite-agent/builds/rust-llvm-integrate/llvm-project/rust-llvm-integrate-prototype/src/test/assembly/asm/riscv-types.rs:59:11: error: CHECK: expected string not found in input --   | // CHECK: lb t0, %pcrel_lo(.Lpcrel_hi0)(t0)   | ^   | /var/lib/buildkite-agent/builds/rust-llvm-integrate/llvm-project/rust-llvm-integrate-prototype/build/x86_64-unknown-linux-gnu/test/assembly/asm/riscv-types.riscv64/riscv-types.s:24:36: note: scanning from here   | auipc t0, %pcrel_hi(extern_static)   | ^   | /var/lib/buildkite-agent/builds/rust-llvm-integrate/llvm-project/rust-llvm-integrate-prototype/build/x86_64-unknown-linux-gnu/test/assembly/asm/riscv-types.riscv64/riscv-types.s:25:2: note: possible intended match here   | lb t0, %pcrel_lo(.Lpcrel_hi18)(t0)   | ^ ``` As far as I can tell, the exact index in the label probably doesn't matter for the test, especially if LLVM can change it to ~arbitrary values, though I'm not an ASM or RISC-V expert. This [fixes the test](https://buildkite.com/llvm-project/rust-llvm-integrate-prototype/builds/12427).

2022-08-02Rollup merge of #100011 - compiler-errors:let-chain-restriction, r=fee1-deadMatthias Krüger-248/+332
Use Parser's `restrictions` instead of `let_expr_allowed` This also means that the `ALLOW_LET` flag is reset properly for subexpressions, so we can properly deny things like `a && (b && let c = d)`. Also the parser is a tiny bit smaller now. It doesn't reject _all_ bad `let` expr usages, just a bit more. cc `@c410-f3r`

Thin `AssocItem` This PR removes a few fields from `AssocItem` that should be easily computed using other queries. This simplifies some of the metadata decoding.
