Add warning for breakage hazard for introducing new builtin attrs
sembr a few files
Fix up `#[linkage]` target checking Fixes rust-lang#134451 r? @JonathanBrouwer
…r=mejrs,JonathanBrouwer Check unsafe impls on safe EIIs Tracking issue: rust-lang#125418 Unsafe EIIs require implementations to use `#[unsafe(...)]`, but safe EIIs currently accept this form as well. This should be rejected, just like `unsafe impl` on a safe trait. This also fixes existing EII UI tests using this pattern and adds a new regression test.
…-never-coercion, r=jieyouxu Add tuple never coercion collection regression test Fixes rust-lang#100727 It's fixed by PR rust-lang#147834
Remove redundant `#[rustc_paren_sugar]` feature gate It is already gated on `rustc_attrs`. Alternatively we could update attribute parsing to optionally require multiple features, but that seems unnecessary. r? @JonathanBrouwer
rustc_parse: Stop returning `Option` from statement parsing `parse_stmt_without_recovery` had one corner case in which it returned `Ok(None)` - when parsing immediately encountered a closing brace `}`, possibly after parsing outer attributes. It is simpler to never call `parse_stmt_without_recovery` in such contexts than deal with a possibility of no statement being returned without an error. So this PR changes the function's return type from `PResult<'a, Option<Stmt>>` to `PResult<'a, Stmt>` and adjusts one call site to check for a closing brace.
Updated expect messages for `CString` struct and method documentation Completes a task with rust-lang#159751. Updates the expect messages in `library/alloc/src/ffi/c_str.rs`.
More cleanup in `rustc_attr_parsing` Follow up to rust-lang#159508. r? @mejrs
Update expect messages in library/alloc/boxed.rs and library/alloc/string.rs to follow the style guide Related issue: rust-lang#159751 Updates the expect messages in library/alloc/boxed.rs and library/alloc/string.rs to follow the style guide.
…uwer Split multiline derives into std/rustc macros Misc cleanup
…nBrouwer Fix `find_attr` hygiene and `rustc_hir` cleanups In particular, `extern crate self as rustc_hir;` leads to very noisy import suggestions if you get an import wrong. Also flatten the `nested_filter` module which seemed to exist just to avoid `None` / `Option:None` nameres conflicts
rustc-dev-guide subtree update Subtree update of `rustc-dev-guide` to rust-lang/rustc-dev-guide@f5333a6. Created using https://github.com/rust-lang/josh-sync. r? @ghost
…target, r=GuillaumeGomez Clarify that the expected runtime symbols signature is for the current target only Some of the signatures expected by our runtime symbols are slightly different from one target to the other one (`i8` vs `u8`), and while the original definition uses type alias, they are not recorded and displayed in the diagnostic. So, to avoid any ambiguity let's add a small note that the displayed signature is only for the current target. r? @GuillaumeGomez
…mejrs Fix error in diagnostic on_unmatched_args fixes rust-lang#159886
rename abort_unwind → abort_on_unwind As suggested in the tracking issue (rust-lang#130338). r? @nia-e Cc @rust-lang/libs-api
