Add temporary broken `./x test library/std` advisory
The last part of the paragraph did not fit
- `for` loops now use two `match`es for all of their bindings. I'm not sure this is the most helpful way of conveying that, but it's about as informative as before while staying brief. - `while let` and `if let` don't use `match`; they use `let` expressions in their conditions. Since `if let` no longer has significantly different desugaring and having a whole bullet point for `while` would feel redundant with `for`, I've removed those examples.
…ring update AST-to-HIR lowering examples for conditionals and loops
adjust autodiff docs, after splitting up autodiff into two macros
- rewrite all `SmirInterface` apis. - add `BridgeTys` to impl those associated types in `Bridge`. - move `**_def()` stuffs living in `impl Tables` from `rustc_internal` to `stable_mir`.
The previous `rustc_smir::alloc` had many direct calls to rustc queries. This commit splits it into two parts: `rustc_smir::alloc` and `stable_mir::alloc`. Following the same pattern as `SmirCtxt` and `SmirInterface`, the `rustc_smir::alloc` handles all direct interactions with rustc queries and performs the actual memory allocations, while the `stable_mir::alloc` is responsible for constructing stable components.
This commit removes the `Tables` field from `SmirCtxt`, since borrows of `tables` should only be managed by `SmirInterface`. This change prevents `SmirCtxt` from holding separate borrows and requires passing `tables` explicitly when needed. We use the `traits.rs` file to define traits that are used for encapsulating the associated functions in the rustc's internals. This is much easier to use and maintain than directly cramming everything into `SmirCtxt`.
note that this commit delete `convert/error.rs`, we would use `SmirError::from_internal` instead. **Unresolved questions:** - There are still a few direct calls to rustc's internals scattered across `impl Stable`s, but most of them appear to be relatively stable, e.g., `mir::interpret::ConstAllocation::inner(self)` and `mir::syntax::SwitchTargets::otherwise(self)`.
the only functionality of `Tables` is caching results. this commit moves calls to rustc queries from `Tables` to `SmirCtxt`.
bump termize dep Bumps termize to drop one more winapi dep. Only change is really moving from winapi: https://github.com/JohnTitor/termize/releases/tag/v0.2.0 Clippy depends on termize 0.1.1, rust-lang/rust-clippy#15207
