@GuillaumeGomez wanted to check in for what you are looking for from me for reviewing this. cargo pgo is a third party subcommand that I don't even remember if I've heard of before.

GuillaumeGomez · 2023-08-20T11:48:58Z

I have no knowledge about this so set you as reviewer since I know you're in the cargo team and might know more or at least know who to put as reviewer?

@meysam81 @epage Could you please clarify the status of the PR?

meysam81 · 2023-09-12T02:49:21Z

@zamazan4ik
The only concern so far has been whether a backref to community works violates any kind of standard in Rust docs, and perhaps a confirmation/approval of one of the members can benefit in proceeding with this PR. Other than that, we're good to go from my side.

zamazan4ik · 2023-10-21T12:56:12Z

@meysam81 @epage Sorry for the ping but seems like the PR stuck a little. According to the last comment, we need some kind of approval from a Rust dev team member. Do we need to ping someone else to this PR to continue work on it? Because cargo-pgo project is way too helpful for doing PGO across the Rust ecosystem, I want to improve the visibility of such a tool for the Rust community.

I sent a few comments, but as I've said before, I have a conflict of interest here 😆 To move the discussion forward, I'll ask on Zulip if it's ok to include community tools in the official documentation.

src/doc/rustc/src/profile-guided-optimization.md

+```bash
+# Install the binary as usual: cargo install cargo-pgo
+cargo pgo build
+LLVM_PROFILE_FILE=./target/pgo-profiles/rustc-pgo_%m_%p.profraw ./target/x86_64-unknown-linux-gnu/release/myprogram


I would perhaps remove the LLVM_PROFILE_FILE env. var. It's only needed for programs that generate a lot of processes internally (which is not that common), so I think that it could be avoided in this example, to make it simpler.

Reassigning to myself since I am a maintainer/reviewer for these docs.

I wonder when/how is the actual website updated/deployed from the source (?).

ehuss · 2023-10-27T13:34:27Z

When the nightly release is made, the website at https://doc.rust-lang.org/nightly/ is updated.
Similarly, when a beta release is made, https://doc.rust-lang.org/beta/ is updated.
When a stable release is made, the version-specific site is updated, like https://doc.rust-lang.org/1.73.0/, and the aliases at https://doc.rust-lang.org/stable/ and the root https://doc.rust-lang.org/.

Kobzol · 2023-10-27T13:35:29Z

Oh, so it follows the compiler, that makes sense. Thanks!
