2025-09-05compiler: Add Windows resources to rustc-main and rustc_driverAleksey Kliger-0/+26
Adds Windows resources with the rust version information to rustc-main.exe and rustc_driver.dll Sets the product description to "Rust Compiler" or "Rust Compiler (channel)" for non-stable channels
2025-04-02Remove `recursion_limit` increases.Nicholas Nethercote-1/+0
These are no longer needed now that `Nonterminal` is gone.
2025-03-07Increase recursion_limit in numerous crates.Nicholas Nethercote-0/+1
This is temporarily needed for `x doc compiler` to work. They can be removed once the `Nonterminal` is removed (#124141).

2024-06-12Use `tidy` to sort crate attributes for all compiler crates.Nicholas Nethercote-1/+3
We already do this for a number of crates, e.g. `rustc_middle`, `rustc_span`, `rustc_metadata`, `rustc_span`, `rustc_errors`. For the ones we don't, in many cases the attributes are a mess. - There is no consistency about order of attribute kinds (e.g. `allow`/`deny`/`feature`). - Within attribute kind groups (e.g. the `feature` attributes), sometimes the order is alphabetical, and sometimes there is no particular order. - Sometimes the attributes of a particular kind aren't even grouped all together, e.g. there might be a `feature`, then an `allow`, then another `feature`. This commit extends the existing sorting to all compiler crates, increasing consistency. If any new attribute line is added there is now only one place it can go -- no need for arbitrary decisions. Exceptions: - `rustc_log`, `rustc_next_trait_solver` and `rustc_type_ir_macros`, because they have no crate attributes. - `rustc_codegen_gcc`, because it's quasi-external to rustc (e.g. it's ignored in `rustfmt.toml`).
2023-11-15Bump cfg(bootstrap)sMark Rousskov-3/+3
2023-10-30Clean up `rustc_*/Cargo.toml`.Nicholas Nethercote-0/+2
- Sort dependencies and features sections. - Add `tidy` markers to the sorted sections so they stay sorted. - Remove empty `[lib`] sections. - Remove "See more keys..." comments. Excluded files: - rustc_codegen_{cranelift,gcc}, because they're external. - rustc_lexer, because it has external use. - stable_mir, because it has external use.
2023-10-16docs: add Rust logo to more compiler cratesMichael Howell-0/+4
c6e6ecb1afea9695a42d0f148ce153536b279eb5 added it to some of the compiler's crates, but avoided adding it to all of them to reduce bit-rot. This commit adds to more.

2023-01-29Rollup merge of #107006 - b-naber:thir-tree, r=jackh726Matthias Krüger-0/+15
Output tree representation on thir-tree The current output of `-Zunpretty=thir-tree` is really cumbersome to work with, using an actual tree representation should make it easier to see what the thir looks like.

Add log-backtrace option to show backtraces along with logging according to #90698, I added a compiler option, `-Zlog-backtrace=filter`, where `filter` is a module name, to show backtraces for logging without rebuilding. resolve #90698
2023-01-12Auto merge of #105603 - oli-obk:non_repeatable_queries, r=petrochenkovbors-5/+6
Harden the pre-tyctxt query system against accidental recomputation While the current compiler has no issues where we `take` and then compute the query again, in https://github.com/rust-lang/rust/pull/105462 I accidentally introduced such a case. I also took the opportunity to remove `peek_mut`, which is only ever used for `global_tcx` to then invoke `enter`. I added an `enter` method directly on the query.

Fix `rustdoc --version` when used with download-rustc Previously, rustdoc would unconditionally report the version that *rustc* was compiled with. That showed things like `nightly-2022-10-30`, which wasn't right, since this was a `dev` build compiled from source. Fix it by changing `rustc_driver::version` to a macro expanded at invocation time. cc https://github.com/rust-lang/rust/issues/103206#issuecomment-1284123084

2022-11-01Auto merge of #103217 - mejrs:track, r=eholkbors-0/+1
Track where diagnostics were created. This implements the `-Ztrack-diagnostics` flag, which uses `#[track_caller]` to track where diagnostics are created. It is meant as a debugging tool much like `-Ztreat-err-as-bug`. For example, the following code... ```rust struct A; struct B; fn main(){ let _: A = B; } ``` ...now emits the following error message: ``` error[E0308]: mismatched types --> src\main.rs:5:16 | 5 | let _: A = B; | - ^ expected struct `A`, found struct `B` | | | expected due to this -Ztrack-diagnostics: created at compiler\rustc_infer\src\infer\error_reporting\mod.rs:2275:31 ```
2022-10-25Remove `rustc_driver::set_sigpipe_handler()`Martin Nordholts-12/+0
Its usage was removed in 5e624bf4ba and 093b075d32, so we do not need to keep it around any longer. According to [preliminary input](https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp/topic/Find.20.60rustc_driver.60.20dependent.20projects.3F/near/304490764), we do not need to worry about any deprecation cycle for this API and can just straight up remove it. Migration instructions for remaining clients -------------------------------------------- Change from ```rust extern crate rustc_driver; fn main() { rustc_driver::set_sigpipe_handler(); // ... ``` to ```rust fn main() { // ... ```
