compiler & tools: bump windows crate to dedupe versions

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.

Fix logical error with what text is considered whitespace.

2024-12-17T04:34:46+00:00

There is a logical issue around what counts as leading white-space. There is code which does a subtraction assuming that no errors will be reported inside the leading whitespace. However we compute the length of that whitespace with std::char::is_whitespace and not rustc_lexer::is_whitespace. The former will include a no-break space while later will excluded it. We can only safely make the assumption that no errors will be reported in whitespace if it is all "Rust Standard" whitespace. Indeed an error does occur in unicode whitespace if it contains a no-break space.

Delete the `cfg(not(parallel))` serial compiler

2024-11-12T13:38:58+00:00

Since it's inception a long time ago, the parallel compiler and its cfgs have been a maintenance burden. This was a necessary evil the allow iteration while not degrading performance because of synchronization overhead. But this time is over. Thanks to the amazing work by the parallel working group (and the dyn sync crimes), the parallel compiler has now been fast enough to be shipped by default in nightly for quite a while now. Stable and beta have still been on the serial compiler, because they can't use `-Zthreads` anyways. But this is quite suboptimal: - the maintenance burden still sucks - we're not testing the serial compiler in nightly Because of these reasons, it's time to end it. The serial compiler has served us well in the years since it was split from the parallel one, but it's over now. Let the knight slay one head of the two-headed dragon!

compiler: Add rustc_abi dependence to the compiler

2024-10-28T04:10:58+00:00

Depend on rustc_abi in compiler crates that use it indirectly but have not yet taken on that dependency, and are not entangled in my other PRs. This leaves an "excise rustc_target" step after the dust settles.
