With this change, the lint checks all operations that are defined as
being capable of overflow in the Rust Reference.

Fix warning for unused variables in or pattern (issue #67691)
Is this a good way to fix it?
Also, the tests fail, the "fixed" code output says `{ i, j }` instead of `{ i, j: _ }`, how can I fix that?

Add some basic docs to `sym` and `kw` modules
I was looking into improving some Clippy documentation but was missing a
place that explains the `kw` and `sym` modules from rustc.
This adds some very basic usage documentation to these modules.

Normalize source when loading external foreign source into SourceMap
The compiler normalizes source when reading files initially (removes BOMs, etc), but not when loading external sources.
This leads to the external source matching according to the `src_hash`, but differing internally because it was not normalized.
Fixes #70874.

Update links of `rustc guide`
Picks up the things we left behind in the transition, hopefully they're last ones.

Handle `impl Trait` where `Trait` has an assoc type with missing bounds
When encountering a type parameter that needs more bounds the trivial case is `T` `where T: Bound`, but it can also be an `impl Trait` param that needs to be decomposed to a type param for cleaner code. For example, given
```rust
fn foo(constraints: impl Iterator) {
for constraint in constraints {
println!("{:?}", constraint);
}
}
```
the previous output was
```
error[E0277]: `<impl Iterator as std::iter::Iterator>::Item` doesn't implement `std::fmt::Debug`
--> src/main.rs:3:26
|
1 | fn foo(constraints: impl Iterator) {
| - help: consider further restricting the associated type: `where <impl Iterator as std::iter::Iterator>::Item: std::fmt::Debug`
2 | for constraint in constraints {
3 | println!("{:?}", constraint);
| ^^^^^^^^^^ `<impl Iterator as std::iter::Iterator>::Item` cannot be formatted using `{:?}` because it doesn't implement `std::fmt::Debug`
|
= help: the trait `std::fmt::Debug` is not implemented for `<impl Iterator as std::iter::Iterator>::Item`
= note: required by `std::fmt::Debug::fmt`
```
which is incorrect as `where <impl Iterator as std::iter::Iterator>::Item: std::fmt::Debug` is not valid syntax nor would it restrict the positional `impl Iterator` parameter if it were.
The output being introduced is
```
error[E0277]: `<impl Iterator as std::iter::Iterator>::Item` doesn't implement `std::fmt::Debug`
--> src/main.rs:3:26
|
3 | println!("{:?}", constraint);
| ^^^^^^^^^^ `<impl Iterator as std::iter::Iterator>::Item` cannot be formatted using `{:?}` because it doesn't implement `std::fmt::Debug`
|
= help: the trait `std::fmt::Debug` is not implemented for `<impl Iterator as std::iter::Iterator>::Item`
= note: required by `std::fmt::Debug::fmt`
help: introduce a type parameter with a trait bound instead of using `impl Trait`
|
LL | fn foo<T: Iterator>(constraints: T) where <T as std::iter::Iterator>::Item: std::fmt::Debug {
| ^^^^^^^^^^^^^ ^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
```
This suggestion is correct and lead the user in the right direction: because you have an associated type restriction you can no longer use `impl Trait`, the only reasonable alternative is to introduce a named type parameter, bound by `Trait` and with a `where` binding on the associated type for the new type parameter `as Trait` for the missing bound.
*Ideally*, we would want to suggest something like the following, but that is not valid syntax today
```
error[E0277]: `<impl Iterator as std::iter::Iterator>::Item` doesn't implement `std::fmt::Debug`
--> src/main.rs:3:26
|
3 | println!("{:?}", constraint);
| ^^^^^^^^^^ `<impl Iterator as std::iter::Iterator>::Item` cannot be formatted using `{:?}` because it doesn't implement `std::fmt::Debug`
|
= help: the trait `std::fmt::Debug` is not implemented for `<impl Iterator as std::iter::Iterator>::Item`
= note: required by `std::fmt::Debug::fmt`
help: introduce a type parameter with a trait bound instead of using `impl Trait`
|
LL | fn foo(constraints: impl Iterator<Item: std::fmt::Debug>) {
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
```
Fix #69638.

The compiler normalizes source when reading files initially (removes BOMs, etc), but not when loading external sources.
Fixes #70874 by normalizing when loading external sources too. Adds a test to verify normalization.

rustc: Add a warning count upon completion
This adds a `build completed with one warning/x warnings` message, similar to the already present `aborted due to previous error` message.

x.py sets it unconditionally, so want it for plain "cargo build".
We need to load one of the panic runtimes that is in src (vs. pre-built in the
compiler's sysroot) to ensure that we don't load libpanic_unwind from the
sysroot. That would lead to a load of libcore, also from the sysroot, and create
lots of errors about duplicate lang items.
|
|
The code was broken because it printed "llvm-config" instead of the
absolute path to the llvm-config executable, causing Cargo to always
rebuild librustc_llvm if using system LLVM.
Also, it's not the build system's job to rebuild when a system library
changes, so we simply don't emit "rerun-if-changed" if a path to LLVM
was not explicitly provided.

rustc_session exports it for other crates to avoid mismatching
crate versions.
