Use the right span when encountering an enum variant followed by an associated item so we don't lose the associated item in the resulting code.
Do not suggest the thing twice, once as a removal of the associated item and a second time as a typo suggestion.
The target name can be anything with custom target specs. Matching on
fields inside the target spec is much more robust than matching on the
target name.
Operations like is_aligned would return actively wrong results at compile-time,
i.e. calling it on the same pointer at compiletime and runtime could yield
different results. That's no good.
Instead of having hacks to make align_offset kind-of work in const-eval, just
use const_eval_select in the few places where it makes sense, which also ensures
those places are all aware they need to make sure the fallback behavior is
consistent.
This commit is the final step in the journey of renaming the historical
`wasm32-wasi` target in the Rust compiler to `wasm32-wasip1`. Various
steps in this journey so far have been:
* 2023-04-03: rust-lang/compiler-team#607 - initial proposal for this rename
* 2024-11-27: rust-lang/compiler-team#695 - amended schedule/procedure for rename
* 2024-01-29: rust-lang/rust#120468 - initial introduction of `wasm32-wasip1`
* 2024-06-18: rust-lang/rust#126662 - warn on usage of `wasm32-wasi`
* 2024-11-08: this PR - remove the `wasm32-wasi` target
The full transition schedule is in [this comment][comment] and is
summarized with:
* 2024-05-02: Rust 1.78 released with `wasm32-wasip1` target
* 2024-09-05: Rust 1.81 released warning on usage of `wasm32-wasi`
* 2025-01-09: Rust 1.84 to be released without the `wasm32-wasi` target
This means that support on stable for the replacement target of
`wasm32-wasip1` has currently been available for 6 months. Users have
already seen warnings on stable for 2 months about usage of
`wasm32-wasi` and stable users have another 2 months of warnings before
the target is removed from stable.
This commit is intended to be the final step in this transition so the
source tree should no longer mention `wasm32-wasi` except in historical
reference to the older name of the `wasm32-wasip1` target.

Port most of `--print=target-cpus` to Rust
The logic and formatting needed by `--print=target-cpus` has historically been carried out in C++ code. Originally it used `printf` to write directly to the console, but later it switched over to writing to a `std::ostringstream` and then passing its buffer to a callback function pointer.
This PR replaces that C++ code with a very simple function that writes a list of CPU names to a `&RustString`, with the rest of the logic and formatting being handled by ordinary safe Rust code.
compiler: Continue introducing rustc_abi to the compiler
Some crates have not heard of rustc_abi before, so arrange introductions.
Encourage some crates to go further and leave rustc_target behind: it was no good for them.
Do not format generic consts
We introduced **nightly support** for generic const items in #113522, but formatting of consts was not modified. Making them format *correctly* is hard, so let's just bail formatting them so we don't accidentally strip their generics and where clauses. This is essentially no-op formatting for generic const items.

make codegen help output more consistent
The output of `rustc -C help` generally has one option per line. There was one exception because of a (presumably) forgotten line continuation escape.
PassWrapper: adapt for llvm/llvm-project@b01e2a8b56
A boolean turned into an enum. None matches the old behavior of false, so we pass that.

Add `--print host-tuple` to print host target tuple
People often parse `-vV` output to get to the host tuple, which is annoying to do. It's easier to just get it directly.
I called it "host-tuple" instead of "host" because it's clearer that it's just the target name. I'm open to different names, but I think this one is fine.
a quick GitHub search for `'^host` reveals many instances of people doing the parsing, for example:
68e0ca57cd/README.md (L369)0e38473b0c/main.sh (L96)8a3553b865/README.md (L625)43f3ec3970/do.sh (L35)
needs a compiler FCP. I could also do an MCP but I think just an FCP here makes the most sense.
AddressSanitizer adds instrumentation to global variables unless the
[`no_sanitize_address`](https://llvm.org/docs/LangRef.html#global-attributes)
attribute is set on them.
This commit extends the existing `#[no_sanitize(address)]` attribute to
set this; previously it only had the desired effect on functions.

* Remove redundant wording
* Introduce trait diff highlighting logic and use it
* Fix incorrect "long type written to path" logic (can be split off)
* Point at tail expression in more cases in E0277
* Avoid long primary span labels in E0277 by moving them to a `help`
Fix#132013.
There are individual commits that can be their own PR. If the review load is too big, happy to split them off.
As with ab5583ed1e, we had been explicitly
passing defaults whose type have changed. Rather than do an ifdef, we
simply rely on the defaults.
@rustbot label: +llvm-main
We don't see a reason to explicitly pass the default here, so just use
the default instead of explicitly passing it and needing an ifdef.

Also treat `impl` definition parent as transparent regarding modules
This PR changes the `non_local_definitions` lint logic to also consider `impl` definition parent as transparent regarding modules.

Move versioned Apple LLVM targets from `rustc_target` to `rustc_codegen_ssa`
Fully specified LLVM targets contain the OS version on macOS/iOS/tvOS/watchOS/visionOS, and this version depends on the deployment target environment variables like `MACOSX_DEPLOYMENT_TARGET`, `IPHONEOS_DEPLOYMENT_TARGET` etc.
We would like to move this to later in the compilation pipeline, both because it feels impure to access environment variables when fetching target information, but mostly because we need access to more information from https://github.com/rust-lang/rust/pull/130883 to do https://github.com/rust-lang/rust/issues/118204. See also https://github.com/rust-lang/rust/pull/129342#issuecomment-2335156119 for some discussion.
The first and second commit does the actual refactor, it should be a non-functional change, the third commit adds diagnostics for invalid deployment targets, which are now possible to do because we have access to the session.
Tested with the same commands as in https://github.com/rust-lang/rust/pull/130435.
