2023-11-04Remove support for compiler plugins.Nicholas Nethercote-15/+1
They've been deprecated for four years. This commit includes the following changes. - It eliminates the `rustc_plugin_impl` crate. - It changes the language used for lints in `compiler/rustc_driver_impl/src/lib.rs` and `compiler/rustc_lint/src/context.rs`. External lints are now called "loaded" lints, rather than "plugins" to avoid confusion with the old plugins. This only has a tiny effect on the output of `-W help`. - E0457 and E0498 are no longer used. - E0463 is narrowed, now only relating to unfound crates, not plugins. - The `plugin` feature was moved from "active" to "removed". - It removes the entire plugins chapter from the unstable book. - It removes quite a few tests, mostly all of those in `tests/ui-fulldeps/plugin/`. Closes #29597.

2023-10-30Remove out-of-date comment.Nicholas Nethercote-2/+0
It was added in 51938c61f6f1b26e463f9071716f543543486e72, a commit with a 7,720 line diff and a one line commit message. Even then the comment was incorrect; there was a removed a `build_output_filenames` call with a `&[]` argument in rustdoc, but the commit removed that call. In such a large commit, it's easy for small errors to occur.

Fix inline const pattern unsafety checking in THIR Fix THIR unsafety checking of inline constants. - Steal THIR in THIR unsafety checking (if enabled) instead of MIR lowering. - Represent inline constants in THIR patterns.

2023-10-16Fix inline const pattern unsafety checking in THIRMatthew Jasper-2/+6
THIR unsafety checking was getting a cycle of function unsafety checking -> building THIR for the function -> evaluating pattern inline constants in the function -> building MIR for the inline constant -> checking unsafety of functions (so that THIR can be stolen) This is fixed by not stealing THIR when generating MIR but instead when unsafety checking. This leaves an issue with pattern inline constants not being unsafety checked because they are evaluated away when generating THIR. To fix that we now represent inline constants in THIR patterns and visit them in THIR unsafety checking.

2023-06-21Remove Queries::ongoing_codegen.Nicholas Nethercote-2/+2
There's no need to store it in `Queries`. We can just use a local variable, because it's always used shortly after it's produced. The commit also removes the `tcx.analysis()` call in `ongoing_codegen`, because it's easy to ensure that's done beforehand. All this makes the dataflow within `run_compiler` easier to follow, at the cost of making one test slightly more verbose, which I think is a good tradeoff.

2023-06-06Write to stdout if `-` is given as output fileJing Peng-28/+47
If `-o -` or `--emit KIND=-` is provided, output will be written to stdout instead. Binary output (`obj`, `llvm-bc`, `link` and `metadata`) being written this way will result in an error unless stdout is not a tty. Multiple output types going to stdout will trigger an error too, as they will all be mixded together.
2023-05-19Auto merge of #111641 - michaelwoerister:debugger-visualizer-fixes, r=cjgillotbors-0/+5
Fix dependency tracking for debugger visualizers This PR fixes dependency tracking for debugger visualizer files by changing the `debugger_visualizers` query to an `eval_always` query that scans the AST while it is still available. This way the set of visualizer files is already available when dep-info is emitted. Since the query is turned into an `eval_always` query, dependency tracking will now reliably detect changes to the visualizer script files themselves.

Only depend on CFG_VERSION in rustc_interface This avoids having to rebuild the whole compiler on each commit when `omit-git-hash = false`. cc https://github.com/rust-lang/rust/issues/76720 - this won't fix it, and I'm not suggesting we turn this on by default, but it will make it less painful for people who do have `omit-git-hash` on as a workaround.

Specialize query execution for incremental and non-incremental This specializes query execution for incremental and non-incremental by passing in a separate `dyn QueryEngine` types, taking advantage of the virtual dispatch to avoid a branch. This ends up duplicating `try_execute_query`, hopefully the compile time cost of that is relatively low. This is a performance improvement for the non-incremental path: <table><tr><td rowspan="2">Benchmark</td><td colspan="1"><b>Before</b></th><td colspan="2"><b>After</b></th></tr><tr><td align="right">Time</td><td align="right">Time</td><td align="right">%</th></tr><tr><td>🟣 <b>clap</b>:check</td><td align="right">1.8420s</td><td align="right">1.8331s</td><td align="right"> -0.48%</td></tr><tr><td>🟣 <b>hyper</b>:check</td><td align="right">0.2652s</td><td align="right">0.2631s</td><td align="right"> -0.78%</td></tr><tr><td>🟣 <b>regex</b>:check</td><td align="right">1.0161s</td><td align="right">1.0062s</td><td align="right"> -0.98%</td></tr><tr><td>🟣 <b>syn</b>:check</td><td align="right">1.6408s</td><td align="right">1.6197s</td><td align="right">💚 -1.28%</td></tr><tr><td>🟣 <b>syntex_syntax</b>:check</td><td align="right">6.3939s</td><td align="right">6.3558s</td><td align="right"> -0.60%</td></tr><tr><td>Total</td><td align="right">11.1580s</td><td align="right">11.0780s</td><td align="right"> -0.72%</td></tr><tr><td>Summary</td><td align="right">1.0000s</td><td align="right">0.9918s</td><td align="right"> -0.82%</td></tr></table> The incremental path is more neutral: <table><tr><td rowspan="2">Benchmark</td><td colspan="1"><b>Before</b></th><td colspan="2"><b>After</b></th></tr><tr><td align="right">Time</td><td align="right">Time</td><td align="right">%</th></tr><tr><td>🟣 <b>clap</b>:check:initial</td><td align="right">2.2210s</td><td align="right">2.2227s</td><td align="right"> 0.08%</td></tr><tr><td>🟣 <b>hyper</b>:check:initial</td><td align="right">0.3441s</td><td align="right">0.3443s</td><td align="right"> 0.05%</td></tr><tr><td>🟣 <b>regex</b>:check:initial</td><td align="right">1.2919s</td><td align="right">1.2877s</td><td align="right"> -0.33%</td></tr><tr><td>🟣 <b>syn</b>:check:initial</td><td align="right">2.0749s</td><td align="right">2.0721s</td><td align="right"> -0.14%</td></tr><tr><td>🟣 <b>syntex_syntax</b>:check:initial</td><td align="right">7.9266s</td><td align="right">7.9206s</td><td align="right"> -0.07%</td></tr><tr><td>Total</td><td align="right">13.8585s</td><td align="right">13.8474s</td><td align="right"> -0.08%</td></tr><tr><td>Summary</td><td align="right">1.0000s</td><td align="right">0.9992s</td><td align="right"> -0.08%</td></tr></table> r? `@cjgillot`

Run various queries from other queries instead of explicitly in phases These are just legacy leftovers from when rustc didn't have a query system. While there are more cleanups of this sort that can be done here, I want to land them in smaller steps. This phased order of query invocations was already a lie, as any query that looks at types (e.g. the wf checks run before) can invoke e.g. const eval which invokes borrowck, which invokes typeck, ...

2023-03-23Rollup merge of #109231 - Zoxc:fs-non-canon, r=eholkMatthias Krüger-2/+3
Add `try_canonicalize` to `rustc_fs_util` and use it over `fs::canonicalize` This adds `try_canonicalize` which tries to call `fs::canonicalize`, but falls back to `std::path::absolute` if it fails. Existing `canonicalize` calls are replaced with it. `fs::canonicalize` is not guaranteed to work on Windows.
2023-03-23rustc_interface: Add a new query `pre_configure`Vadim Petrochenkov-24/+27
It partially expands crate attributes before the main expansion pass (without modifying the crate), and the produced preliminary crate attribute list is used for querying a few attributes that are required very early. Crate-level cfg attributes are then expanded normally during the main expansion pass, like attributes on any other nodes.
