2022-07-20Rollup merge of #99436 - Nilstrieb:toggle-box-noalias, r=fee1-deadDylan DPC-0/+1
Add flag to configure `noalias` on `Box<T>` The aliasing rules of `Box<T>` are still not decided, but currently, `Box<T>` is unique and gets `noalias`. To aid making an informed decision about the future of `Box<T>`, this PR adds a flag `-Zbox-noalias` to configure `noalias` for `Box<T>` (for example, for benchmarking). The same flag already exists for `&mut T` `noalias`, where it was added because it was the problem of various miscompilations in LLVM. For more information, see rust-lang/unsafe-code-guidelines#326

To aid making an informed decision about the aliasing rules of box, give users an option to remove `noalias` from box.

2022-07-08Rollup merge of #95635 - davidtwco:terminal-width-stabilization, r=oli-obkMatthias Krüger-0/+20
sess: stabilize `--terminal-width` as `--diagnostic-width` Formerly `-Zterminal-width`, `--terminal-width` allows the user or build tool to inform rustc of the width of the terminal so that diagnostics can be truncated. Pending agreement to stabilize, see tracking issue at #84673. r? ```@oli-obk```
2022-07-06session: `output-width` -> `diagnostic-width`David Wood-3/+3
Rename the `--output-width` flag to `--diagnostic-width` as this appears to be the preferred name within the compiler team. Signed-off-by: David Wood <david.wood@huawei.com>
2022-07-06session: `terminal-width` -> `output-width`David Wood-3/+3
Rename the `--terminal-width` flag to `--output-width` as the behaviour doesn't just apply to terminals (and so is slightly less accurate). Signed-off-by: David Wood <david.wood@huawei.com>

Fix bug in `rustdoc -Whelp` Previously, this printed the debugging options, not the lint options, and only handled `-Whelp`, not `-A/-D/-F`. This also fixes a few other misc issues: - Fix `// check-stdout` for UI tests; previously it only worked for run-fail and compile-fail tests - Add lint headers for tool lints, not just builtin lints https://github.com/rust-lang/rust/pull/98533#issuecomment-1172004197 r? ```@GuillaumeGomez```

rustdoc: Resolve doc links on fields during early resolution Another subset of https://github.com/rust-lang/rust/pull/94857 which fixes https://github.com/rust-lang/rust/issues/96429. This case regressed in https://github.com/rust-lang/rust/pull/96135 when `may_have_doc_links`-based filtering was introduced. Before that filtering structs could collect traits in scope for their fields, but after the filtering structs won't collect anything if they don't have doc comments on them, so we have to visit fields too.

2022-04-16Rollup merge of #95887 - petrochenkov:doclink5, r=cjgillotDylan DPC-0/+17
resolve: Create dummy bindings for all unresolved imports Apparently such bindings weren't previously created for all unresolved imports, causing issues like https://github.com/rust-lang/rust/issues/95879. In this PR I'm trying to create such dummy bindings in a more centralized way by calling `import_dummy_binding` once for all imports in `finalize_imports`. Fixes https://github.com/rust-lang/rust/issues/95879.

rustdoc: Fix resolution of `crate`-relative paths in doc links Resolve `crate::foo` paths transparently to rustdoc, so their resolution no longer affects diagnostics and modules used for determining traits in scope. The proper solution is to account for the current `module_id`/`parent_scope` in `fn resolve_crate_root`, but it's a slightly larger compiler changes. This PR moves the code closer to it, but keeps it rustdoc-specific. Fixes https://github.com/rust-lang/rust/issues/78696 Fixes https://github.com/rust-lang/rust/issues/94924
