Description

This is a tracking issue for collecting and triaging bugs and challenges that hinder our ability to produce reproducible and deterministic builds.

This tracking issue is used as a hub for connecting to other relevant issues, e.g., bugs or open design questions. This tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature. Instead, open a dedicated issue for the specific matter and add the https://github.com/rust-lang/rust/labels/A-reproducibility label, and tag with OS/architecture/target labels as suitable.

[!WARNING]

This tracking issue is non-exhaustive. Please add suitable entries and edit as new issues and PRs pop up or if old issues and PRs are rediscovered.

Research direction

Start with tests/run-make/reproducible-builds and review the linked open issues, especially those marked as needing investigation or having unclear status. This tracking issue is a hub rather than a self-contained task; completion depends on selecting a specific reproducibility bug, defining its scope, and updating or resolving the corresponding entry.
