| # This file defines a workflow that runs the libc++ benchmarks when a comment is added to the PR. | |
| # | |
| # The comment is of the form: | |
| # | |
| # /libcxx-bot benchmark <path-to-benchmarks-to-run> | |
| # | |
| # That will cause the specified benchmarks to be run on the PR and on the pull-request target, and | |
| # their results to be compared. | |
