This greatly simplifies how hard it is to set a custom bug report url; previously tools had to copy the entire hook implementation. - Switch clippy to the new hook This also adds a `extra_info` callback so clippy can include its own version number, which differs from rustc's. - Call `install_ice_hook` in rustfmt
When we're adding a method to a type DIE, we only want a DW_AT_declaration there, because LLVM LTO can't unify type definitions when a child DIE is a full subprogram definition. Now the subprogram definition gets added at the CU level with a specification link back to the abstract declaration.

Previously, incorrect spans were reported if inline assembly contained CRLF (Windows) line endings. Fixes rust-lang#110885
… r=lcnr Use fulfillment to check `Drop` impl compatibility Use an `ObligationCtxt` to ensure that a `Drop` impl does not have stricter requirements than the ADT that it's implemented for, rather than using a `SimpleEqRelation` to (more or less) syntactically equate predicates on an ADT with predicates on an impl. r? types ### Some background The old code reads: ```rust // An earlier version of this code attempted to do this checking // via the traits::fulfill machinery. However, it ran into trouble // since the fulfill machinery merely turns outlives-predicates // 'a:'b and T:'b into region inference constraints. It is simpler // just to look for all the predicates directly. ``` I'm not sure what this means, but perhaps in the 8 years since that this comment was written (cc rust-lang#23638) it's gotten easier to process region constraints after doing fulfillment? I don't know how this logic differs from anything we do in the `compare_impl_item` module. Ironically, later on it says: ```rust // However, it may be more efficient in the future to batch // the analysis together via the fulfill (see comment above regarding // the usage of the fulfill machinery), rather than the // repeated `.iter().any(..)` calls. ``` Also: * Removes `SimpleEqRelation` which was far too syntactical in its relation. * Fixes rust-lang#110557
Add Terminator conversion from MIR to SMIR, part #1 This adds internal MIR TerminatorKind to SMIR Terminator conversion. r? ```@oli-obk```

Make the BUG_REPORT_URL configurable by tools This greatly simplifies how hard it is to set a custom bug report url; previously tools had to copy the entire hook implementation. I haven't changed clippy in case they want to make the change upstream instead of the subtree, but I'm happy to do so here if the maintainers want - cc ````@rust-lang/clippy```` Fixes rust-lang#109486.
…michaelwoerister debuginfo: split method declaration and definition When we're adding a method to a type DIE, we only want a DW_AT_declaration there, because LLVM LTO can't unify type definitions when a child DIE is a full subprogram definition. Now the subprogram definition gets added at the CU level with a specification link back to the abstract declaration. Both GCC and Clang write debuginfo this way for C++ class methods. Fixes rust-lang#109730. Fixes rust-lang#109934.

add hint for =< as <=
Adds a compiler hint for when `=<` is typed instead of `<=`
Example hint:
```rust
fn foo() {
if 1 =< 3 {
println!("Hello, World!");
}
}
```
```
error: expected type, found `3`
--> main.rs:2:13
|
2 | if 1 =< 3 {
| -- ^ expected type
| |
| help: did you mean: `<=`
```
This PR only emits the suggestion if there is no space between the `=` and `<`. This hopefully narrows the scope of when this error is emitted, however this still allows this error to be emitted in cases such as this:
```
error: expected expression, found `;`
--> main.rs:2:18
|
2 | if 1 =< [i32;; 3]>::hello() {
| -- ^ expected expression
| |
| help: did you mean: `<=`
```
Which could be a good reason not to merge since I haven't been able to think of any other ways of narrowing the scope of this diagnostic.
closes rust-lang#111128
… r=cjgillot More robust debug assertions for `Instance::resolve` on built-in traits with non-standard trait items In rust-lang#111264, a user added a new item to the `Future` trait, but the code in [`resolve_associated_item`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_ty_utils/instance/fn.resolve_associated_item.html) implicitly assumes that the `Future` trait is defined with only one method (`Future::poll`) and treats the generator body as the implementation of that method. This PR adds some debug assertions to make sure that that new methods defined on `Future`/`Generator`/etc. don't accidentally resolve to the wrong item when they are added, and adds a helpful comment guiding a compiler dev (or curious `#![no_core]` user) to what must be done to support adding new associated items to these built-in implementations. I am open to discuss whether a test should be added, but I chose against it because I opted to make these `bug!()`s instead of, e.g., diagnostics or fatal errors. Arguably it doesn't need a test because it's not a bug that can be triggered by an end user, and internal-facing misuses of core kind of touch on rust-lang/compiler-team#620 -- however, I think the assertions I added in this PR are still a very useful way to make sure this bug doesn't waste debugging resources down the line. Fixes rust-lang#111264
