| # This workflow checks if a PR commit has changed the size of a hello world Rust program. | |
| # It downloads Rustc and compiles two versions of a stage0 compiler - one using the base commit | |
| # of the PR, and one using the latest commit in the PR. | |
| # If the size of the hello world program has changed, it posts a comment to the PR. | |
