Nicholas Nethercote 75b164d836 Use `tidy` to sort crate attributes for all compiler crates. 
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`).

Mark Rousskov db3e2bacb6 Bump cfg(bootstrap)s 2023-11-15 19:41:28 -05:00
Nicholas Nethercote 8ff624a9f2 Clean up `rustc_*/Cargo.toml`. 
- 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.

Michael Howell 2ff2624722 docs: add Rust logo to more compiler crates 
c6e6ecb1af 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.

Rollup merge of #107006 - b-naber:thir-tree, r=jackh726

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

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.

compiler: remove unnecessary imports and qualified paths 2022-12-10 18:45:34 +01:00
Oli Scherer d30848b30a Use `Symbol` for the crate name instead of `String`/`str` 2022-12-07 20:30:02 +00:00
Nicholas Nethercote 67cfe2cfbb Remove `-Zno-interleave-lints`. 
Because it complicates lint implementation greatly.

bors 872631d0f0 Auto merge of #104507 - WaffleLapkin:asderefsyou, r=wesleywiser 
Use `as_deref` in compiler (but only where it makes sense)

This simplifies some code :3

(there are some changes that are not exacly `as_deref`, but more like "clever `Option`/`Result` method use")

Rollup merge of #103117 - joshtriplett:use-is-terminal, r=eholk 
Use `IsTerminal` in place of `atty`

In any crate that can use nightly features, use `IsTerminal` rather than
`atty`:

- Use `IsTerminal` in `rustc_errors`
- Use `IsTerminal` in `rustc_driver`
- Use `IsTerminal` in `rustc_log`
- Use `IsTerminal` in `librustdoc`

Rollup merge of #104184 - jyn514:rustdoc-version, r=davidtwco 
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.

Kamil Koczurek 4c3cad0620 Add --print=split-debuginfo 
This option prints all supported values for -Csplit-debuginfo=.., i.e.
only stable ones on stable/beta and all of them on nightly/dev.

bors 11ebe6512b Auto merge of #103217 - mejrs:track, r=eholk 
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
```

Martin Nordholts 43e17454e2 Remove `rustc_driver::set_sigpipe_handler()` 
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() {
    // ...
```

Migrate all diagnostics 2022-10-23 10:09:44 +02:00
Nicholas Nethercote cf13d9143d Clarify `run_in_thread_pool_with_globals`. 
- Make the structure of the two variants more similar.
- Add some comments.
- Move various conditional `use` items inside the function that uses
  them.
- Inline some closures.
