This is more in-line with what Apple's tooling expects, and allows us to
better support custom compiler drivers (such as certain Homebrew and
Nixpkgs compilers) that prefer their own `-isysroot` flag.
Effectively, we now invoke the compiler driver as-if it was invoked as
`xcrun -sdk $sdk_name $tool`.

This is a documentation-only deprecation for now.
Over time, we can
- warn and then remove on use of unstable environment variables
- warn on use of stable environment variables (no plan to remove due to
compatibility)
Longer term, we expect test runners, like `cargo test`, to provide the
necessary mechanisms for environmental or persistent configuration (e.g.
using cargo config which supports `.cargo/config.toml` as well as
environment variables).
This would include:
- `RUST_TEST_THREADS`
- `RUST_TEST_NOCAPTURE`
- `RUST_TEST_SHUFFLE` (unstable)
- `RUST_TEST_SHUFFLE_SEED` (unstable)
The primary outcomes for this change are
- Reducing the scope of what is expected for custom test harnesses to
implement
- Reduce the mechanisms that test runners, like `cargo test`, are
expected to track when they are being bypassed to protect against
negative interactions, e.g. `RUST_TEST_NOCAPTURE=1` when json output
is being read.

They could easily get out of sync and miss some fields. Now all steps are instrumented automatically.
|
|
When verbose mode is enabled, it is very hard to see the actually executed steps.
|
|
|
|
|
|
So that it is easier to see which was the last started step when a failure happens on CI.

Ship correct Cranelift library in its dist component
The first commit adds a post-dist UI test to check that Cranelift can be used with the extracted dist x64 Linux archive.
The original codegen copy logic in the Cranelift dist step was a bit redundant, and I didn't notice in https://github.com/rust-lang/rust/pull/144787 that it's copying the codegen backend from the build compiler's sysroot, rather than the target compiler's sysroot. The second commit modifies the logic to directly access the built codegen file (there is no need to search for it in the compiler's sysroot, in fact when you run just `x dist rustc_codegen_cranelift`, it shouldn't "taint" the sysroot with the codegen backend! Which it did before https://github.com/rust-lang/rust/pull/144787) and copy it to the tarball under a normalized name. Thus we get around any similar potential issues in the future, and make previously implicit logic more explicit.
This also fixes running just `x dist rustc_codegen_cranelift` without enabling `cranelift` in `rust.codegen-backends`, which should have been enabled by https://github.com/rust-lang/rust/pull/144787, but it didn't work fully, because the dist step tried to copy the codegen backend from the compiler's sysroot, but it didn't contain the codegen backend if it was not enabled by `rust.codegen-backends`.

Fix Cargo cross-compilation (take two)
In https://github.com/rust-lang/rust/pull/145083, I fixed the case of manually invoking `x dist cargo`, but I realized that `x install` creates the `tool::Cargo` step through the `from_build_frompiler` constructor, which doesn't go through `get_tool_target_compiler`. So we just prepare both the host and target stdlibs directly before building Cargo. Ideally we would get rid of `from_build_compiler`, but that will require refactoring the dist and test steps, which is upcoming.
Hopefully fixes https://github.com/rust-lang/rust/issues/145059 for good.

Enable RUST_BACKTRACE=1 on CI
We should really see the backtrace if something in bootstrap fails on CI. https://github.com/rust-lang/rust/pull/145011#issuecomment-3172664934 doesn't show many details.

Enforce in bootstrap that doc must have stage at least 1
Following with the bootstrap cleanups, this time around `doc` steps. Should be pretty straightforward, because the supporting infrastructure was already there.
The only thing I found a bit fishy is using `Mode::ToolBootstrap` as a "catch-all" mode for non-rustc-private steps in `tool_doc!`, but I don't think that we need to distinguish the tools in some special way when documenting them, apart from supporting `rustc_private`.
Before, `x doc` more or less defaulted to what we call stage 2 now. Now it is properly stage 1, so e.g. `x doc compiler` documents the compiler using the stage0/beta rust(do)c.

Shourya742:2025-07-08-convert-config-method-invoke-inside-parse-functions, r=Kobzol
Make config method invoke inside parse use dwn_ctx
This PR is part of a series of config refactorings. It removes calls from config methods to solid functions defined in `config.rs`. After this, we will remove the default dependencies in the config.

Constify remaining traits/impls for `const_ops`
Tracking issue: rust-lang/rust#143802
This is split into two commits for ease of reviewability:
1. Updates the `forward_ref_*` macros to accept multiple attributes (in anticipation of needing `rust_const_unstable` attributes) and also *require* attributes in these macros. Since the default attribute only helps for the initial implementations, it means it's easy to get wrong for future implementations, as shown for the saturating implementations which were incorrect before.
2. Actually constify the traits/impls.
A few random other notes on the implementation specifically:
* I unindented the attributes that were passed to the `forward_ref_*` macro calls because in some places rustfmt wanted them to be unindented, and in others it was allowed because they were themselves inside of macro bodies. I chose the consistent indenting even though I (personally) think it looks worse.
----
As far as the actual changes go, this constifies the following additional traits:
* `Neg`
* `Not`
* `BitAnd`
* `BitOr`
* `BitXor`
* `Shl`
* `Shr`
* `AddAssign`
* `SubAssign`
* `MulAssign`
* `DivAssign`
* `RemAssign`
* `BitAndAssign`
* `BitOrAssign`
* `BitXorAssign`
* `ShlAssign`
* `ShrAssign`
In terms of constified implementations of these traits, it adds the reference-forwarded versions of all the arithmetic operators, which are defined by the macros in `library/core/src/internal_macros.rs`. I'm not going to fully enumerate these because we'd be here all day, but sufficed to say, it effectively allows adding an `&` to one or both sides of an operator for primitives.
Additionally, I constified the implementations for `Wrapping`, `Saturating`, and `NonZero` as well, since all of them forward to already-const-stable methods. (potentially via intrinsics, to avoid extra overhead)
There are three "non-primitive" types which implement these traits, listed below. Note that I put "non-primitive" in quotes since I'm including `Wrapping`, `Saturating`, and `NonZero`, which are just wrappers over primitives.
* `Duration` (arithmetic operations)
* `SystemTime` (arithmetic operations)
* `Ipv4Addr` (bit operations)
* `Ipv6Addr` (bit operations)
Additionally, because the methods on `SystemTime` needed to make these operations const were not marked const, a separate tracking issue for const-stabilising those methods is rust-lang/rust#144517.
Stuff left out of this PR:
* `Assume` (this could trivially be made const, but since the docs indicate this is still under heavy design, I figured I'd leave it out)
* `Instant` (this could be made const, but cannot reasonably be constructed at constant time, so, isn't useful)
* `SystemTime` (will submit separate PR)
* SIMD types (I'm tackling these all at once later; see rust-lang/portable-simd#467)
