- consistent handling, invalid handles are always an abort
- Helper for reading handles that does the checking and machine stop
- Use real handle types more places
- Adds `File` and `Invalid` types of handle. File support will be added next

Add `*_value` methods to proc_macro lib
This is the (re-)implementation of https://github.com/rust-lang/libs-team/issues/459.
It allows to get the actual value (unescaped) of the different string literals.
It was originally done in https://github.com/rust-lang/rust/pull/136355 but it broke the artifacts build so we decided to move the crate to crates.io to go around this limitation.
Part of https://github.com/rust-lang/rust/issues/136652.
Considering this is a copy-paste of the originally approved PR, no need to go through the whole process again. \o/

tidy: Fix paths to `coretests` and `alloctests`
Following `#135937` and `#136642`, tests for core and alloc are in coretests and alloctests. Fix tidy to lint for the new paths. Also, update comments referring to the old locations.
Some context for changes which don't match that pattern:
- `library/std/src/thread/local/dynamic_tests.rs` and `library/std/src/sync/mpsc/sync_tests.rs` were moved under `library/std/tests/` in 332fb7e6f1d (Move std::thread_local unit tests to integration tests, 2025-01-17) and b8ae372e483 (Move std::sync unit tests to integration tests, 2025-01-17), respectively, so are no longer special cases.
- There never was a `library/core/tests/fmt.rs` file. That comment previously referred to `src/test/ui/ifmt.rs`, which was folded into `library/alloc/tests/fmt.rs` in 949c96660c3 (move format! interface tests, 2020-09-08).
Now, the only matches for `(alloc|core)/tests` are in `compiler/rustc_codegen_{cranelift,gcc}/patches`. I don't know why CI hasn't broken because those patches can't apply. Or maybe they somehow still can apply?

Expose algebraic floating point intrinsics
# Problem
A stable Rust implementation of a simple dot product is 8x slower than C++ on modern x86-64 CPUs. The root cause is an inability to let the compiler reorder floating point operations for better vectorization.
See https://github.com/calder/dot-bench for benchmarks. Measurements below were performed on a i7-10875H.
### C++: 10us ✅
With Clang 18.1.3 and `-O2 -march=haswell`:
<table>
<tr>
<th>C++</th>
<th>Assembly</th>
</tr>
<tr>
<td>
<pre lang="cc">
float dot(float *a, float *b, size_t len) {
#pragma clang fp reassociate(on)
float sum = 0.0;
for (size_t i = 0; i < len; ++i) {
sum += a[i] * b[i];
}
return sum;
}
</pre>
</td>
<td>

</tr>
</table>
### Nightly Rust: 10us ✅
With rustc 1.86.0-nightly (8239a37f9) and `-C opt-level=3 -C target-feature=+avx2,+fma`:
<table>
<tr>
<th>Rust</th>
<th>Assembly</th>
</tr>
<tr>
<td>
<pre lang="rust">
fn dot(a: &[f32], b: &[f32]) -> f32 {
let mut sum = 0.0;
for i in 0..a.len() {
sum = fadd_algebraic(sum, fmul_algebraic(a[i], b[i]));
}
sum
}
</pre>
</td>
<td>
<img src="https://github.com/user-attachments/assets/9dcf953a-2cd7-42f3-bc34-7117de4c5fb9" />
</td>
</tr>
</table>
### Stable Rust: 84us ❌
With rustc 1.84.1 (e71f9a9a9) and `-C opt-level=3 -C target-feature=+avx2,+fma`:
<table>
<tr>
<th>Rust</th>
<th>Assembly</th>
</tr>
<tr>

# Proposed Change
Add `core::intrinsics::f*_algebraic` wrappers to `f16`, `f32`, `f64`, and `f128` gated on a new `float_algebraic` feature.
# Alternatives Considered
https://github.com/rust-lang/rust/issues/21690 has a lot of good discussion of various options for supporting fast math in Rust, but is still open a decade later because any choice that opts in more than individual operations is ultimately contrary to Rust's design principles.
In the mean time, processors have evolved and we're leaving major performance on the table by not supporting vectorization. We shouldn't make users choose between an unstable compiler and an 8x performance hit.

feat(project-model): provide flag for no deps

Cargo update

davidbarsky/davidbarsky/fix-panic-in-view-crate-graph
internal: fix panic in `view_crate_graph`
|
|
fix: don't drop references with more than one definition.
|
|
|
|
Implicit field references during struct initialization were
being dropped because get_definition was returning None because
there were multiple definitions.
This adds a new helper, `get_defintions`, that supports returning
more than one definition for a given token and hooks it up.
Fixes #19393

|
|
|
|
|
A Cargo project can now be built without any dependency metadata being fetched.

compiletest: Encapsulate all of the code that touches libtest
Compiletest currently relies on unstable libtest APIs in order to actually execute tests. That's unfortunate, but removing the dependency isn't trivial.
However, we can make a small step towards removing the libtest dependency by encapsulating the libtest interactions into a single dedicated module. That makes it easier to see what parts of libtest are actually used.
---
As a side-effect of moving the `test_opts` function into that dedicated module, this PR also ends up allowing `--fail-fast` to be passed on the command line, instead of requiring an environment variable.
---
There is still (at least) one other aspect of the libtest dependency that this PR does not address, namely the fact that we rely on libtest's output capture (via unstable std APIs) to capture the output that we print during individual tests. I hope to do something about that at some point.
