| # Runs the pytest suite (IR generation + LLC compilation). Kernel verifier | |
| # tests additionally need passwordless sudo and a kernel with BTF/BPF | |
| # enabled, which isn't guaranteed on every runner, so we probe for working | |

| # `push` is scoped to master only: branches here live in this repo rather | |
| # than forks, so a push to a branch with an open PR would otherwise fire | |
| # both `push` and `pull_request` for the same commit, running everything | |
| # twice. `pull_request` covers feature branches; `push` still gives master | |
| # a post-merge check. | |
