The `max_line_length` property was set to 100 for all filetypes, which
led to git commit messages being wrapped at 100 characters instead of
the usual 75. This introduces an exception for the special file used by
git to write commit messages.

A new syntax node `ast::VariantDef` has been introduced to map between the HIR node and the AST.
The files have been updated with `cargo test -p xtask`.

trim channel value in `get_closest_merge_commit`
This was a silly bug which caused `git_upstream_merge_base` to never work because it was `nightly\n` not `nightly`.
bootstrap and compiletest: Use `size_of_val` from the prelude instead of imported
Use `std::mem::size_of_val` from the prelude instead of importing or qualifying it.
This function was added to all preludes in Rust 1.80.

Add timestamp to unstable feature usage metrics
part of https://github.com/rust-lang/rust/issues/129485
with this we should be able to temporarily enable metrics on docs.rs to gather a nice test dataset for the initial PoC dashboard

Specifically, when a rename of a local will change some code that refers it to refer another local, or some code that refer another local to refer to it.
We do it by introducing a dummy edit with an annotation. I'm not a fond of this approach, but I don't think LSP has a better way.
This is required to format evaluated consts, because we need trait env, and it needs the crate (currently it uses the last crate in topological order, which is wrong, the next commit will fix that).
interpret/provenance_map: consistently use range_is_empty
https://github.com/rust-lang/rust/pull/137704 started using this for per-ptr provenance; let's be consistent and use it also for the per-byte provenance check. Also rename the methods to avoid having both "get" and "is_empty" in the name.

Improve error message for `AsyncFn` trait failure for RPIT
Use a `WellFormedDerived` obligation cause to make sure we can turn an `AsyncFnKindHelper` trait goal into its parent `AsyncFn*` goal, then fix the logic for reporting `AsyncFn*` kind mismatches.

Add minimal platform support documentation for powerpc-unknown-linux-gnuspe
Per https://github.com/rust-lang/rust/pull/137860#issuecomment-2692358259, add minimal platform support documentation, including a brief summary and links to more detailed information about this target.
The added documentation is minimal. This is somewhat similar to [powerpc-unknown-openbsd, which also has no target maintainer](https://doc.rust-lang.org/nightly/rustc/platform-support/powerpc-unknown-openbsd.html). The rest of the template is left to target maintainers.
I also updated powerpc-unknown-linux-muslspe platform support documentation and added link to powerpc-unknown-linux-gnuspe platform support documentation.

Provide more context on resolve error caused from incorrect RTN
When encountering a resolve E0575 error for an associated method (when a type was expected), see if it could have been an intended return type notation bound.
```
error[E0575]: expected associated type, found associated function `Trait::method`
--> $DIR/bad-inputs-and-output.rs:31:36
|
LL | fn foo_qualified<T: Trait>() where <T as Trait>::method(i32): Send {}
| ^^^^^^^^^^^^^^^^^^^^^^^^^ not a associated type
|
help: you might have meant to use the return type notation syntax
|
LL - fn foo_qualified<T: Trait>() where <T as Trait>::method(i32): Send {}
LL + fn foo_qualified<T: Trait>() where T::method(..): Send {}

Clarify why InhabitedPredicate::instantiate_opt exists
At first glance, the extra casework seems pointless and needlessly error-prone. Clarify that there is a reason for it being there.
Do not require that unsafe fields lack drop glue
Instead, we adopt the position that introducing an `unsafe` field itself carries a safety invariant: that if you assign an invariant to that field weaker than what the field's destructor requires, you must ensure that field is in a droppable state in your destructor.

miri native-call support: all previously exposed provenance is accessible to the callee
When Miri invokes a native C function, the memory C can access needs to be "prepared": to avoid false positives, we need to consider all that memory initialized, and we need to consider it to have arbitrary provenance. So far we did this for all pointers passed to C, but not for pointers that were exposed already before the native call. This PR adjusts the logic so that we now "prepare" all memory that has ever been exposed.
This fixes cases such as:
- cast a pointer to integer, send that integer to C, and access the memory there (`test_pass_ptr_as_int`)
- send a pointer to some memory to C, which stores it somewhere; then in Rust store another pointer in that memory, and access that via C (`test_pass_ptr_via_previously_shared_mem`)

Fix char count in `Display` for `ByteStr`
`ByteStr as Display` performs a byte count when a char count is required.

fix usage of ty decl macro fragments in attributes
See the test case. Due to one missing code path (and also the changes in #137517), using $ty or other specific fragments as part of an attr wouldn't work. $tt used to work since it wouldn't be parsed anywhere along the way.
Closes#137662
Re-add `Clone`-derive on `Thir`
This PR adds back `Clone` for `Thir`.
If a tool wants to access a `thir_body` query result in the `Callbacks::after_analysis` hook, it can't do so (I think) without a `Clone` impl on `Thir`, because `check_unsafety` steals the value. With `Clone`, the `thir_body` query provider can be overriden to cache a clone of the `Thir`, circumventing that issue.
Specifically, we need it for https://github.com/rust-corpus/qrates, [here](ca7a230196/extractor/src/lib.rs (L205)).
Please let me know if there are issues with this PR/if there's another way to solve the problem at hand
Add DWARF test case for non-C-like `repr128` enums
LLVM 20 fixes DWARF debuginfo for non-C-like 128-bit enums: this PR adds a test case to the `repr128-dwarf` test to ensure that LLVM doesn't regress in the future.

Try to point of macro expansion from resolver and method errors if it involves macro var
In the case that a macro caller passes an identifier into a macro generating a path or method expression, point out that identifier in the context of the *macro* so it's a bit more clear how the macro is involved in causing the error.

Match Ergonomics 2024: add context and examples to the unstable book
The examples here are pretty limited and don't illustrate the differences between the two feature gates, but my hope is that they get the general idea across. I can try and add some more nuance or more comprehensive examples too if that would help.
Hopefully the doctest isn't too sneaky. I wanted to make the bindings' types explicit, and the most readable way I could think of was to use a helper.
~~Unfortunately it looks like the "run this code" button doesn't work yet, but I made sure the examples are cross-edition, so that should resolve on its own once playground's nightly updates (or if playground's default becomes edition 2024, or if the edition in the markdown gets forwarded to playground).~~ It looks like the default edition on playground is now 2024, so the run button works! There's no output, but having a button to show that it compiles is nice, I think.
