4c1f51bf6e Fix link failure on AVR (incompatible ISA error)
Fixes #137739. A reproducer of the issue is present there. I believe the
root cause was introducing the avr-none target (which has no CPU by
default) and trying to get the ISA revision from there. This commit
uses the `target-cpu` option instead, which is already required to be
present for the target.

adb5ecabdb Tweak invalid RTN errors
Make suggestions verbose.

When encountering `method(type)` bound, suggest `method(..)` instead of `method()`.

```
error: argument types not allowed with return type notation
  --> $DIR/bad-inputs-and-output.rs:9:23
   |
LL | fn foo<T: Trait<method(i32): Send>>() {}
   |                       ^^^^^
   |
help: remove the input types
   |
LL - fn foo<T: Trait<method(i32): Send>>() {}
LL + fn foo<T: Trait<method(..): Send>>() {}
   |
```

When encountering both return type and arg list that isn't `..`, suggest replacing both.

9f9a822509 Check for MSRV attributes in late passes using the HIR (#13821)
Closes https://github.com/rust-lang/rust-clippy/issues/13169

Late lints now use a parent iter to check for `#[clippy::msrv]`
attributes instead of keeping track with `extract_msrv_attr`. This is
required for incremental lints since they run per module instead of per
crate so don't visit all the necessary attributes

As a basic optimisation if no `#[clippy::msrv]` attributes are
discovered in early passes the HIR access is skipped completely and just
the configured MSRV is used, for most code bases this will be the case

cdef38812d Use correct error message casing for io::const_errors
Error messages are supposed to start with lowercase letters, but a lot
of `io::const_error` messages did not. This fixes them to start with a
lowercase letter.
I did consider adding a const check for this to the macro, but some of
them start with proper nouns that make sense to uppercase them.

91034adf30 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.

7d4d09eeeb Shorten span of panic failures in const context
Previously, we included a redundant prefix on the panic message and a postfix of the location of the panic. The prefix didn't carry any additional information beyond "something failed", and the location of the panic is redundant with the diagnostic's span, which gets printed out even if its code is not shown.

4606610b21 Rollup merge of #137673 - ChrisDenton:search-path-bug, r=dtolnay
Fix Windows `Command` search path bug

Currently `Command::new` on Windows works differently depending on whether any environment variable is set. For example,

```rust
// Searches for "myapp" in the application and system paths first (aka Windows native behaviour).
Command::new("myapp").spawn();

// Search for "myapp" in `PATH` first
Command::new("myapp").env("a", "b").spawn();
```

This is a bug because the search path should only change if `PATH` is changed for the child (i.e. `.env("PATH", "...")`).

This was discussed in a libs-api meeting where the exact semantics of `Command::new` was not decided but there seemed to be broad agreement that this particular thing is just a bug that can be fixed.

50ed7f974b Rollup merge of #137599 - davidtwco:use-minicore-more, r=jieyouxu
tests: use minicore more

minicore makes it much easier to add new language items to all of the existing `no_core` tests.

Most of the remaining tests that *could* use minicore either fail because..

1. LLVM IR output changes and doesn't pass the test as written. I didn't look into these further.
2. The test has revisions w/ different compilation flags, expecting some to fail, and when using minicore, minicore is compiled with those flags and fails in the expected way because of the flags rather than the test, and that's considered a failure.

But these tests can be changed and make adding new language items a lot easier.

50ef985be2 Rollup merge of #137551 - folkertdev:import-simd-intrinsics, r=RalfJung
import `simd_` intrinsics

In most cases, we can import the simd intrinsics rather than redeclare them. Apparently, most of these tests were written before `std::intrinsics::simd` existed.

There are a couple of exceptions where we can't yet import:

- the intrinsics are not declared as `const fn` in the standard library, causing issues in the `const-eval` tests
- the `simd_shuffle_generic` function is not exposed from `std::intrinsics`
- the `simd_fpow` and `simd_fpowi` functions are not exposed from `std::intrinsics` (removed in https://github.com/rust-lang/rust/pull/137595)
- some tests use `no_core`, and therefore cannot use `std::intrinsics`

Add FileCheck annotations to mir-opt/issues

This resolves a part of #116971 .

The directory `tests/mir-opt/issues` has only one test issue_75439.rs which should add FileCheck annotations.

Originally it was introduced in #75580 to confirm that there were duplicated basic blocks against or-patterns, but in #123067 the duplication was resolved. So FileCheck should ensure that there is no such duplication any more.

update enzyme to handle range metadata

r? `@oli-obk`

I landed two PRs over the last days, one of which is especially important because Enzyme now handles range metadata correctly. This allows a larger Rust project to compile.

Fix enzyme build errors

After [this PR](https://github.com/rust-lang/rust/pull/136428) was merged, I switched to master and attempted building `./x.py build --stage 1 library` with the config mentioned in the enzyme rustbook but it resulted in some errors tho the config.example.toml build succeeded
The errors were re:
### 1. Use of ref in match patterns
The errors were related to match ergonomics in Rust 2024, where ref is no longer needed when matching on references. Examples:
```

error: could not compile `rustc_builtin_macros` (lib) due to 4 previous errors
warning: build failed, waiting for other jobs to finish...
Build completed unsuccessfully in 0:19:39
```
### 2. the use of external C blocks without unsafe in compiler/rustc_codegen_llvm/src/llvm/enzyme_ffi.rs (I don't have the error message handy)

The first commit fixes the errors above

---
## Additional Improvement:
`@ZuseZ4` suggested we consolidate the variants under `#[cfg(llvm_enzyme)]` and `#[cfg(not(llvm_enzyme))]` by conditionally checking for `cfg!(llvm_enzyme)` instead. This way,  the autodiff code is compiled but not executed avoiding such regressions
