2023-11-06Auto merge of #117435 - SparrowLii:nightly_parallel, r=oli-obk,davidtwcobors-2/+21
enable parallel rustc front end in nightly builds Refers to the [MCP](https://github.com/rust-lang/compiler-team/issues/681), this pr does: 1. Enable the parallel front end in nightly builds, and keep the default number of threads as 1. Then users can use the parallel rustc front end via -Z threads=n option. 2. Set it up to serial front end for beta/stable builds via bootstrap. 3. Switch over the alt builders from parallel rustc to serial, so we have artifacts without parallel to test against the artifacts with parallel. r? `@oli-obk` cc `@cjgillot` `@nnethercote` `@bjorn3` `@Kobzol`

2023-11-03Use `filter_map` in `try_par_for_each_in`Josh Stone-7/+6
This simplifies the expression, especially for the rayon part, and also lets us drop the `E: Copy` constraint.

Avoid a `track_errors` by bubbling up most errors from `check_well_formed` I believe `track_errors` is mostly papering over issues that a sufficiently convoluted query graph can hit. I made this change, while the actual change I want to do is to stop bailing out early on errors, and instead use this new `ErrorGuaranteed` to invoke `check_well_formed` for individual items before doing all the `typeck` logic on them. This works towards resolving https://github.com/rust-lang/rust/issues/97477 and various other ICEs, as well as allowing us to use parallel rustc more (which is currently rather limited/bottlenecked due to the very sequential nature in which we do `rustc_hir_analysis::check_crate`) cc `@SparrowLii` `@Zoxc` for the new `try_par_for_each_in` function

Remove `IdFunctor` trait. It's defined in `rustc_data_structures` but is only used in `rustc_type_ir`. The code is shorter and easier to read if we remove this layer of abstraction and just do the things directly where they are needed. r? `@BoxyUwU`

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.

Switching to `Ordering::then_with` makes control-flow less complicated, and there is no need to use `partial_cmp` here.
2023-09-11Rollup merge of #115548 - Zoxc:parallel-extract, r=wesleywiserMatthias Krüger-171/+193
Extract parallel operations in `rustc_data_structures::sync` into a new `parallel` submodule This extracts parallel operations in `rustc_data_structures::sync` into a new `parallel` submodule. This cuts down on the size of the large `cfg_if!` in `sync` and makes it easier to compare between serial and parallel variants.
2023-09-11Auto merge of #115388 - Zoxc:sharded-lock, r=SparrowLiibors-194/+242
Add optimized lock methods for `Sharded` and refactor `Lock` This adds methods to `Sharded` which pick a shard and also locks it. These branch on parallelism just once instead of twice, improving performance.

elaborate a bit on the (lack of) safety in 'Mmap::map' Sadly none of the callers of this function even consider it worth mentioning in their unsafe block that what they are doing is completely unsound.

2023-08-24Auto merge of #115082 - Zoxc:syntax-context-decode-race, r=cjgillotbors-0/+6
Fix races conditions with `SyntaxContext` decoding This changes `SyntaxContext` decoding to work with concurrent decoding. The `remapped_ctxts` field now only stores `SyntaxContext` which have completed decoding, while the new `decoding` and `local_in_progress` keeps track of `SyntaxContext`s which are in process of being decoding and on which threads. This fixes 2 issues with the current implementation. It can return an `SyntaxContext` which contains dummy data if another thread starts decoding before the first one has completely finished. Multiple threads could also allocate multiple `SyntaxContext`s for the same `raw_id`.
