• Leads: @michaelwoerister
• Meeting Notes: All

What is the goal of this working group?

This working group aims to accomplish the following:

• Implement and stabilize profile-guided optimization in rustc.

How can I get involved?

If you are interested in getting involved in this working group, send a message in the Zulip stream.

• Desired experience level: LLVM + PGO expert ;)
• Relevant repositories: rust-lang/rust
• Zulip stream: #t-compiler/wg-profile-guided-optimization on Zulip

Are there any resources so I can get up to speed?

There are some resources available for those interested in contributing to get some background and context:

• Clang's documentation on PGO. Contains lots of useful information on PGO in LLVM.
• @emilio's initial PR for adding experimental support for PGO.

Do I need to attend any meetings?

No.
