src/parallel-rustc.md Outdated
Comment on lines 3 to 9
As of <!-- date-check --> August 2022, the only stage of the compiler that is
parallel is [code generation stage][codegen] (codegen). Some parts of the
compiler have parallel implementations, such as query evaluation, type check
and [monomorphization][monomorphization], but the general version of the
compiler does not include parallelization functions. **To try out the current
parallel compiler**, install `rustc` from source code with `parallel-compiler =
true` in the `Config.toml`.

cc @SparrowLii I feel like some of this is quite outdated, right?

Thanks for the PR!

A lot of content in this article needs to be updated, my opinion is we merge this PR first, after the #132282 merged I will carry on the complete update work.

Update #113349

Most of the rust compilers are now parallelized.

The codegen part is executed concurrently by default. You can use the -C codegen-units=n option to control the number of concurrent tasks.

The parts after HIR lowering to codegen such as type checking, borrowing checking, and mir optimization are parallelized in the nightly version. Currently, they are executed in serial by default, and parallelization is manually enabled by the user using the -Z threads = n option.

Other parts, such as lexical parsing, HIR lowering, and macro expansion, are still executed in serial mode.

I'll slightly adjust this to reflect your wording and then back link to the issue to update the docs for parallel front-end.
