| # This job is meant for testing whether the compiler can be built | |
| # reproducibly given the same build environment. | |
| # | |
| # There are two tools used for this test: | |
| # | |
| # - reprotest: This tool varies the environment in multiple ways, like | |
| # adjusting time, build user, locale, etc. then run the build. | |
| # If the binary matches the control build (build without any | |
| # variations), then it's a pass. Otherwise, diffoscope is | |
| # employed to show the differences. | |
| # | |
| # - diffoscope: This tool visualize differences in binaries in a | |
| # human-readable fashion. This would allow developers to | |
| # figure out what of their changes caused the build to | |
| # varies based on outside environment. | |
| # Skip this for PRs | |
