Revert introduction of `[workspace.dependencies]`.

2025-09-02T09:12:54+00:00

This was done in #145740 and #145947. It is causing problems for people using r-a on anything that uses the rustc-dev rustup package, e.g. Miri, clippy. This repository has lots of submodules and subtrees and various different projects are carved out of pieces of it. It seems like `[workspace.dependencies]` will just be more trouble than it's worth.

Add `tracing` to `[workspace.dependencies]`.

Add `thin-vec` to newly added `[workspace.dependencies]`.

Do not get proc_macro from the sysroot in rustc

2025-05-27T15:49:28+00:00

With the stage0 refactor the proc_macro version found in the sysroot will no longer always match the proc_macro version that proc-macros get compiled with by the rustc executable that uses this proc_macro. This will cause problems as soon as the ABI of the bridge gets changed to implement new features or change the way existing features work. To fix this, this commit changes rustc crates to depend directly on the local version of proc_macro which will also be used in the sysroot that rustc will build.

Revert "Use workspace lints for crates in `compiler/` #138084"

2025-03-10T10:12:47+00:00

Revert to buy time to consider options that avoids breaking downstream usages of cargo on distributed `rustc-src` artifacts, where such cargo invocations fail due to inability to inherit `lints` from workspace root manifest's `workspace.lints` (this is only valid for the source rust-lang/rust workspace, but not really the distributed `rustc-src` artifacts). This breakage was reported in . This reverts commit 48caf81484b50dca5a5cebb614899a3df81ca898, reversing changes made to c6662879b27f5161e95f39395e3c9513a7b97028.

Specify rust lints for `compiler/` crates via Cargo.

2025-03-07T21:41:09+00:00

By naming them in `[workspace.lints.rust]` in the top-level `Cargo.toml`, and then making all `compiler/` crates inherit them with `[lints] workspace = true`. (I omitted `rustc_codegen_{cranelift,gcc}`, because they're a bit different.) The advantages of this over the current approach: - It uses a standard Cargo feature, rather than special handling in bootstrap. So, easier to understand, and less likely to get accidentally broken in the future. - It works for proc macro crates. It's a shame it doesn't work for rustc-specific lints, as the comments explain.
