Be more specific when type parameter shadows primitive type When a type parameter shadows a primitive type, the error message was non obvious. For example, given the file `file.rs`: ```rust trait Parser<T> { fn parse(text: &str) -> Option<T>; } impl<bool> Parser<bool> for bool { fn parse(text: &str) -> Option<bool> { Some(true) } } fn main() { println!("{}", bool::parse("ok").unwrap_or(false)); } ``` The output was: ```bash % rustc file.rs error[E0308]: mismatched types --> file.rs:7:14 | 7 | Some(true) | ^^^^ expected type parameter, found bool a | = note: expected type `bool` = note: found type `bool` error: aborting due to previous error ``` We now show extra information about the type: ```bash % rustc file.rs error[E0308]: mismatched types --> file.rs:7:14 | 7 | Some(true) | ^^^^ expected type parameter, found bool a | = note: expected type `bool` (type parameter) = note: found type `bool` (bool) error: aborting due to previous error ``` Fixes #35030

rustbuild: Fix dependency tracking with new Cargo The recent Cargo update changed filenames, which broke a lot of incremental rustbuild builds. What it thought were the output files were indeed no longer the output files! (wreaking havoc). This commit updates this to stop guessing filenames of Cargo and just manage stamp files instead.

clear obligations-added flag with nested fulfillcx This flag is a debugging measure designed to detect cases where we start a snapshot, create type variables, register obligations involving those type variables in the fulfillment cx, and then have to unroll the snapshot, leaving "dangling type variables" behind. HOWEVER, in some cases the flag is wrong. In particular, we sometimes create a "mini-fulfilment-cx" in which we enroll obligations. As long as this fulfillment cx is fully drained before we return, this is not a problem, as there won't be any escaping obligations in the main cx. So we add a fn to save/restore the flag. Fixes #36053. r? @arielb1

Use primitive indexing in slice's Index/IndexMut [T]'s Index implementation is normally not used for indexing, instead the compiler supplied indexing is used. Use the compiler supplied version in Index/IndexMut. This removes an inconsistency: Compiler supplied bound check failures look like this: thread 'main' panicked at 'index out of bounds: the len is 3 but the index is 4' If you convince Rust to use the Index impl for slices, bounds check failure looks like this instead: thread 'main' panicked at 'assertion failed: index < self.len()' The latter is used if you for example use Index generically: ```rust use std::ops::Index; fn foo<T: ?Sized>(x: &T) where T: Index<usize> { &x[4]; } foo(&[1, 2, 3][..]) ```

Assign node ids during macro expansion After this PR, - The `ExtCtxt` can access `resolve`'s `Resolver` through the trait object `ext::base::Resolver`. - The `Resolver` trait object can load macros and replaces today's `MacroLoader` trait object. - The macro expander uses the `Resolver` trait object to resolve macro invocations. - The macro expander assigns node ids and builds the `Resolver`'s `macros_at_scope` map. - This is groundwork for merging import resolution and expansion. - Performance of expansion together with node id assignment improves by ~5%. **EDIT:** Since Github is reordering the commits, here is `git log`: - b54e1e39: Differentiate between monotonic and non-monotonic expansion and only assign node ids during monotonic expansion. - 78c00398: Expand generated test harnesses and macro registries. - f3c2dca3: Remove scope placeholders from the crate root. - c86c8d41: Perform node id assignment and `macros_at_scope` construction during the `InvocationCollector` and `PlaceholderExpander` folds. - 72a63697: Move macro resolution into `librustc_resolve`. - 20b43b23: Rewrite the unit tests in `ext/expand.rs` as a `compile-fail` test. - a9821e16: Refactor `ExtCtxt` to use a `Resolver` instead of a `MacroLoader`. - 60440b22: Refactor `noop_fold_stmt_kind` out of `noop_fold_stmt`. - 50f94f6c: Avoid needless reexpansions. r? @nrc

Fix indeterminism in ty::TraitObject representation. Make sure that projection bounds in `ty::TraitObject` are sorted in a way that is stable across compilation sessions and crate boundaries. This PR + moves `DefPathHashes` up into `librustc` so it can be used there to create a stable sort key for `DefId`s, + changes `PolyExistentialProjection::sort_key()` to take advantage of the above, + and removes the unused `PolyProjectionPredicate::sort_key()` and `ProjectionTy::sort_key()` methods. Fixes #36155

Improve shallow `Clone` deriving `Copy` unions now support `#[derive(Clone)]`. Less code is generated for `#[derive(Clone, Copy)]`. + Unions now support `#[derive(Eq)]`. Less code is generated for `#[derive(Eq)]`. --- Example of code reduction: ``` enum E { A { a: u8, b: u16 }, B { c: [u8; 100] }, } ``` Before: ``` fn clone(&self) -> E { match (&*self,) { (&E::A { a: ref __self_0, b: ref __self_1 },) => { ::std::clone::assert_receiver_is_clone(&(*__self_0)); ::std::clone::assert_receiver_is_clone(&(*__self_1)); *self } (&E::B { c: ref __self_0 },) => { ::std::clone::assert_receiver_is_clone(&(*__self_0)); *self } } } ``` After: ``` fn clone(&self) -> E { { let _: ::std::clone::AssertParamIsClone<u8>; let _: ::std::clone::AssertParamIsClone<u16>; let _: ::std::clone::AssertParamIsClone<[u8; 100]>; *self } } ``` All the matches are removed, bound assertions are more lightweight. `let _: Checker<CheckMe>;`, unlike `checker(&check_me);`, doesn't have to be translated by rustc_trans and then inlined by LLVM, it doesn't even exist in MIR, this means faster compilation. --- Union impls are generated like this: ``` union U { a: u8, b: u16, c: [u8; 100], } ``` ``` fn clone(&self) -> U { { let _: ::std::clone::AssertParamIsCopy<Self>; *self } } ``` Fixes https://github.com/rust-lang/rust/issues/36043 cc @durka r? @alexcrichton
