`-s` option doesn't perfectly fit into debuginfo()'s semantics and may unexpectedly
remove metadata in shared libraries. Remove the implementation and suggest user to
use `strip` utility instead.

Diagnostic renaming 2
A sequel to #121489.
r? `@davidtwco`
|
|
Make it use `impl Into<DiagMessage>` like all the other methods nearby.
|
|
|
|
|
|
Not the dropping of the trailing `s` -- this type describes a single
diagnostic and its name should be singular.

Add a scheme for moving away from `extern "rust-intrinsic"` entirely
All `rust-intrinsic`s can become free functions now, either with a fallback body, or with a dummy body and an attribute, requiring backends to actually implement the intrinsic.
This PR demonstrates the dummy-body scheme with the `vtable_size` intrinsic.

`ParseSess` cleanups
The main change here is to rename all `ParseSess` values as `psess`. Plus a few other small cleanups.

Extract an arguments struct for `Builder::then_else_break`
Most of this method's arguments are usually or always forwarded as-is to recursive invocations.
Wrapping them in a dedicated struct allows us to document each struct field, and lets us use struct-update syntax to indicate which arguments are being modified when making a recursive call.
---
While trying to understand the lowering of `if` expressions, I found it difficult to keep track of the half-dozen arguments passed through to every call to `then_else_break`. I tried switching over to an arguments struct, and I found that it really helps to make sense of what each argument does, and how each call is modifying the arguments.
I have some further ideas for how to streamline these recursive calls, but I've kept those out of this PR so that it's a pure refactoring with no behavioural changes.

Add a way to add constructors for `rustc_type_ir` types
Introduces a module called `rustc_type_ir`, in which we can place traits which are named `Ty`/`Region`/`Const`/etc. which expose constructors for the `rustc_type_ir` types. This means we can construct things `Interner::Ty` with `Ty::new_x(...)`, which is needed to uplift the new trait solver into an interner-agnostic crate.
These traits are placed into a *separate* module because they're only intended to be used in interner-agnostic code, and they should mirror the constructors that are provided by the inherent constructor methods in `rustc_middle`.
Putting this up for vibe-check mostly. I haven't copied over any of the type constructors, except for one to create bound types for use in the canonicalizer.

constify a couple thread_local statics
|
|
Existing names for values of this type are `sess`, `parse_sess`,
`parse_session`, and `ps`. `sess` is particularly annoying because
that's also used for `Session` values, which are often co-located, and
it can be difficult to know which type a value named `sess` refers to.
(That annoyance is the main motivation for this change.) `psess` is nice
and short, which is good for a name used this much.
The commit also renames some `parse_sess_created` values as
`psess_created`.

Add a new `wasm32-wasip1` target to rustc
This commit adds a new target called `wasm32-wasip1` to rustc. This new target is explained in these two MCPs:
* https://github.com/rust-lang/compiler-team/issues/607
* https://github.com/rust-lang/compiler-team/issues/695
In short, the previous `wasm32-wasi` target is going to be renamed to `wasm32-wasip1` to better live alongside the [new `wasm32-wasip2` target](https://github.com/rust-lang/rust/pull/119616). This new target is added alongside the `wasm32-wasi` target and has the exact same definition as the previous target. This PR is effectively a rename of `wasm32-wasi` to `wasm32-wasip1`. Note, however, that as explained in rust-lang/compiler-team#695 the previous `wasm32-wasi` target is not being removed at this time. This change will reach stable Rust before even a warning about the rename will be printed. At this time this change is just the start where a new target is introduced and users can start migrating if they support only Nightly for example.

Properly deal with GATs when looking for method chains to point at
Fixes #121898.
~~While it prevents an ICE and the structured suggestion is correct, the method chain diagnostic notes are weird / useless / incorrect judging by a quick look. I guess I should improve that in this PR.~~ Sufficiently taken care of.

It's always empty.

It doesn't need a `Parser` and a `ParseSess`, because the former
contains the latter.

Always generate GEP i8 / ptradd for struct offsets
This implements #98615, and goes a bit further to remove `struct_gep` entirely.
Upstream LLVM is in the beginning stages of [migrating to `ptradd`](https://discourse.llvm.org/t/rfc-replacing-getelementptr-with-ptradd/68699). LLVM 19 will [canonicalize](https://github.com/llvm/llvm-project/pull/68882) all constant-offset GEPs to i8, which has roughly the same effect as this change.
Fixes #121719.
Split out from #121577.

Consider middle segments of paths in `unused_qualifications`
Currently `unused_qualifications` looks at the last segment of a path to see if it can be trimmed, this PR extends the check to the middle segments also
```rust
// currently linted
use std::env::args();
std::env::args(); // Removes `std::env::`
```
```rust
// newly linted
use std::env;
std::env::args(); // Removes `std::`
```
Paths with generics in them are now linted as long as the part being trimmed is before any generic args, e.g. it will now suggest trimming `std::vec::` from `std::vec::Vec<usize>`
Paths with any segments that are from an expansion are no longer linted
Fixes #100979
Fixes #96698

Add new `pattern_complexity` attribute to add possibility to limit and check recursion in pattern matching
Needed for https://github.com/rust-lang/rust-analyzer/issues/9528.
This PR adds a new attribute only available when running rust testsuite called `pattern_complexity` which allows to set the maximum recursion for the pattern matching. It is quite useful to ensure the complexity doesn't grow, like in `tests/ui/pattern/usefulness/issue-118437-exponential-time-on-diagonal-match.rs`.
