…Veykril fix: complete enum variants as patterns in pattern path close rust-lang#12593
fix regressions on assignment expressions This is a follow-up PR on rust-lang#12428. I'm not sure if this is everything I overlooked, so if there are more things that are not right, we may want to revert rust-lang#12428. This should also fix the increase of the type mismatches and the unknown types in diesel in the [metrics](https://rust-analyzer.github.io/metrics/?start=2022-06-23&end=2022-07-01) introduced by rust-lang#12428. The regressions are: - some coercions don't work in the ordinary (i.e. non-destructuring) assignments In order for coercions on ADT fields instantiations to work, lhs type has to be known before inferring rhs. rust-lang#12428 changed the inference order, making rhs inferred before lhs, breaking the coercion, so I restored the original inference mechanism for the ordinary assignments. Note that this kind of coercion doesn't happen in destructuring assigments, because when they are desugared, the struct expression is first assigned to a temporary, which is then assigned to the assignee, which is not coercion site anymore. - type mismatches on individual identifiers are not reported
This change fixes issue rust-lang#10037, in more or less the most naive fashion possible. We continue to start with the hardcoded default of "fun_name", and now append a counter to the end of it if that name is already in scope. In the future, we can probably apply more heuristics here to wind up with more useful names by default, but for now this resolves the immediate problem.
…on-duplicate-name, r=DorianListens fix: Extract Function produces duplicate fn names This change fixes rust-lang#10037, in more or less the most naive fashion possible. We continue to start with the hardcoded default of "fun_name", and now append a counter to the end of it if that name is already in scope. In the future, we can probably apply more heuristics here to wind up with more useful names by default, but for now this resolves the immediate problem.
This change fixes rust-lang#10036, "Extract to function assist implements nonexistent trait methods". When we detect that the extraction is coming from within a trait impl, and that a `self` param will be necessary, we adjust which `SyntaxNode` to `insert_after`, and create a new empty `impl` block for the newly extracted function.
Improve documentation for `buildScripts.overrideCommand` / `checkOnSave.overrideCommand`

Pkgsrc changes: * This package now contains rust-analyzer, so implicitly conflicts with that pkgsrc package. The same goes for the rust-src package. * Add NetBSD/arm6 port * Add unfinished NetBSD/mipsel port * Revert the use of the internal LLVM, should now build with the new pkgsrc LLVM (15). * Add depndence on compat80 for sparc64 to fix the build * Adapt patches * Add CHECK_INTERPRETER_SKIP for a few (mostly unused) files.

[This is no longer accepted] (rust-lang/rust#99155). - [`impl Trait` was accidentally accepted as the associated type value of return-position `impl Trait`] (rust-lang/rust#97346), without fulfilling all the trait bounds of that associated type, as long as the hidden type satisfies said bounds. This has been fixed. Internal Changes ---------------- These changes do not affect any public interfaces of Rust, but they represent significant improvements to the performance or internals of rustc and related tools. - Windows builds now use profile-guided optimization, providing 10-20% improvements to compiler performance: [Utilize PGO for windows x64 rustc dist builds] (rust-lang/rust#96978) - [Stop keeping metadata in memory before writing it to disk] (rust-lang/rust#96544) - [compiletest: strip debuginfo by default for mode=ui] (rust-lang/rust#98140) - Many improvements to generated code for derives, including performance improvements: - [Don't use match-destructuring for derived ops on structs.] (rust-lang/rust#98446) - [Many small deriving cleanups] (rust-lang/rust#98741) - [More derive output improvements] (rust-lang/rust#98758) - [Clarify deriving code](rust-lang/rust#98915) - [Final derive output improvements] (rust-lang/rust#99046) - [Stop injecting `#[allow(unused_qualifications)]` in generated `derive` implementations](rust-lang/rust#99485) - [Improve `derive(Debug)`](rust-lang/rust#98190) - [Bump to clap 3](rust-lang/rust#98213) - [fully move dropck to mir](rust-lang/rust#98641) - [Optimize `Vec::insert` for the case where `index == len`.] (rust-lang/rust#98755) - [Convert rust-analyzer to an in-tree tool] (rust-lang/rust#99603)

This re-adds
rust-lang/rust-analyzeras a git subtree rather than a submodule.Closes rust-lang/rust-analyzer#12815.
Prior attempt (research PR): #99465
git rm -f src/tools/rust-analyzergit subtree add -P src/tools/rust-analyzer https://github.com/rust-lang/rust-analyzer.git masterSourceType::InTree,rust-analyzer/in-rust-treefeature when built throughx.pyWith this PR, rust-analyzer becomes an "in-tree" tool. Syncs can happen in both directions, see clippy's relevant book section.
Making sure
proc-macro-srvdoesn't break when the proc_macro bridge changes effectively becomes the responsibility ofrust-lang/rustcontributors. These days, that's mostly @mystor, who has been consulted throughout the process. I'm also making myself available in case there's questions / work needed that nobody else signed up for.This doesn't change rust-analyzer's release cycle. After this PR is merged and the next nightly goes out, one can point
rust-analyzer.procMacro.serverto the rustup-providedrust-analyzerbinary. Changes to improve the situation further (auto-discovery/install of the rust-analyzer component) will happen inrust-lang/rust-analyzerand be synced here eventually.
