In rust-lang#125443 this comment ended up in the wrong spot. I'm not sure why; after careful checking this was the only case I could find like this.
After things that are immediately followed by a `use` declaration and look like they might apply to that `use` item but actually don't.
It has a single use. This makes the `let` handling case in `parse_stmt_without_recovery` more similar to the statement path and statement expression cases.
`parse_expr_assoc_with` has an awkward structure -- sometimes the lhs is already parsed. This commit splits the post-lhs part into a new method `parse_expr_assoc_rest_with`, which makes everything shorter and simpler.
It can be done more concisely.
When collecting tokens there are two kinds of range: - a range relative to the parser's full token stream (which we get when we are parsing); - a range relative to a single AST node's token stream (which we use within `LazyAttrTokenStreamImpl` when replacing tokens). These are currently both represented with `Range<u32>` and it's easy to mix them up -- until now I hadn't properly understood the difference. This commit introduces `ParserRange` and `NodeRange` to distinguish them. This also requires splitting `ReplaceRange` in two, giving the new types `ParserReplacement` and `NodeReplacement`. (These latter two names reduce the overloading of the word "range".) The commit also rewrites some comments to be clearer. The end result is a little more verbose, but much clearer.
Add the feature in `core/lib.rs`
Added SHA512, SM3, SM4 target-features and `sha512_sm_x86` feature gate This is an effort towards rust-lang#126624. This adds support for these 3 target-features and introduces the feature flag `sha512_sm_x86`, which would gate these target-features and the yet-to-be-implemented detection and intrinsics in stdarch.
Add `#[must_use]` to some `into_raw*` functions. cc rust-lang#121287 r? ``@cuviper`` Adds `#[must_use = "losing the pointer will leak memory"]`[^1] to `Box::into_raw(_with_allocator)`, `Vec::into_raw_parts(_with_alloc)`, `String::into_raw_parts`[^2], and `rc::{Rc, Weak}::into_raw_with_allocator` (Rc's normal `into_raw` and all of `Arc`'s `into_raw*`s are already `must_use`). Adds `#[must_use = "losing the raw <resource name may leak resources"]` to `IntoRawFd::into_raw_fd`, `IntoRawSocket::into_raw_socket`, and `IntoRawHandle::into_raw_handle`. [^1]: "*will* leak memory" may be too-strong wording (since `Box`/`Vec`/`String`/`rc::Weak` might not have a backing allocation), but I left it as-is for simplicity and consistency. [^2]: `String::into_raw_parts`'s `must_use` message is changed from the previous (possibly misleading) "`self` will be dropped if the result is not used".
…riddle nested aux-build in tests/rustdoc/ tests * Fixes bug that prevented using nested aux-build in `tests/rustdoc/` tests. Before, `fn document` and the auxiliary builder disagreed about where to find the nested aux-build source file (`auxiliary/auxiliary/aux.rs` vs `auxiliary/aux.rs`), preventing them from building. Picked the latter in line with other builders in compiletest. * Adds `//@ doc-flags` header, which forwards flags to rustdoc and not rustc. * Adds `//@ unique-doc-out-dir` header, which sets the --out-dir for the rustdoc invocation to a unique directory: `<root out dir>/docs/<test name>/doc` * Changes working directory of the rustdoc invocation to the root out directory (common among all aux-builds). Prior art: exec_compiled_test in runtest.rs * Adds tests that use nested aux builds and new headers These changes provide useful capabilities for writing rustdoc tests on their own. They are also needed to test the implementation for the [mergable-rustdoc-cross-crate-info](rust-lang/rfcs#3662) RFC. try-job: x86_64-msvc
