2022-09-16Rollup merge of #101738 - dpaoliello:linkname, r=petrochenkovDylan DPC-4/+3
Fix `#[link kind="raw-dylib"]` to respect `#[link_name]` Issue Details: When using `#[link kind="raw-dylib"]` (#58713), the Rust compiler ignored any `#[link_name]` attributes when generating the import library and so the resulting binary would fail to link due to missing symbols. Fix Details: Use the name from `#[link_name]` if present when generating the `raw-dylib` import library, otherwise default back to the actual symbol name.

2022-03-16rustc_error: make ErrorReported impossible to constructmark-20/+30
There are a few places were we have to construct it, though, and a few places that are more invasive to change. To do this, we create a constructor with a long obvious name.
2022-03-07Clarify `Layout` interning.Nicholas Nethercote-1/+1
`Layout` is another type that is sometimes interned, sometimes not, and we always use references to refer to it so we can't take any advantage of the uniqueness properties for hashing or equality checks. This commit renames `Layout` as `LayoutS`, and then introduces a new `Layout` that is a newtype around an `Interned<LayoutS>`. It also interns more layouts than before. Previously layouts within layouts (via the `variants` field) were never interned, but now they are. Hence the lifetime on the new `Layout` type. Unlike other interned types, these ones are in `rustc_target` instead of `rustc_middle`. This reflects the existing structure of the code, which does layout-specific stuff in `rustc_target` while `TyAndLayout` is generic over the `Ty`, allowing the type-specific stuff to occur in `rustc_middle`. The commit also adds a `HashStable` impl for `Interned`, which was needed. It hashes the contents, unlike the `Hash` impl which hashes the pointer.

2022-01-18Rollup merge of #90782 - ricobbe:binutils-dlltool, r=michaelwoeristerMatthias Krüger-5/+0
Implement raw-dylib support for windows-gnu Add support for `#[link(kind = "raw-dylib")]` on windows-gnu targets. Work around binutils's linker's inability to read import libraries produced by LLVM by calling out to the binutils `dlltool` utility to create an import library from a temporary .DEF file; this approach is effectively a slightly refined version of `@mati865's` earlier attempt at this strategy in PR #88801. (In particular, this attempt at this strategy adds support for `#[link_ordinal(...)]` as well.) In support of #58713.

2021-10-07Rollup merge of #89025 - ricobbe:raw-dylib-link-ordinal, r=michaelwoeristerJubilee-1/+7
Implement `#[link_ordinal(n)]` Allows the use of `#[link_ordinal(n)]` with `#[link(kind = "raw-dylib")]`, allowing Rust to link against DLLs that export symbols by ordinal rather than by name. As long as the ordinal matches, the name of the function in Rust is not required to match the name of the corresponding function in the exporting DLL. Part of #58713.

Move ICH to rustc_query_system Based on https://github.com/rust-lang/rust/pull/89183 The StableHashingContext does not need to be in rustc_middle. This PR moves it to rustc_query_system. This will avoid a dependency between rustc_ast_lowering and rustc_middle in https://github.com/rust-lang/rust/pull/89124.

2021-08-21Remove `Session.used_attrs` and move logic to `CheckAttrVisitor`Aaron Hill-2/+1
Instead of updating global state to mark attributes as used, we now explicitly emit a warning when an attribute is used in an unsupported position. As a side effect, we are to emit more detailed warning messages (instead of just a generic "unused" message). `Session.check_name` is removed, since its only purpose was to mark the attribute as used. All of the callers are modified to use `Attribute.has_name` Additionally, `AttributeType::AssumedUsed` is removed - an 'assumed used' attribute is implemented by simply not performing any checks in `CheckAttrVisitor` for a particular attribute. We no longer emit unused attribute warnings for the `#[rustc_dummy]` attribute - it's an internal attribute used for tests, so it doesn't mark sense to treat it as 'unused'. With this commit, a large source of global untracked state is removed.
