| # Overall approach to running the tests: | |
| # - Install OCaml 5.1, as this is the version of dependencies our merlin expects. | |
| # - Build flambda-backend (which requires installing OCaml 4.14). | |
| # - Build merlin using OCaml 5.1, and then run the tests while pointing merlin at | |
| # flambda-backend's stdlib and ocamlc. | |
| # | |
| # The second step only needs to be run when we update the flambda-backend version, | |
| # so we cache it. We use [upstream/ocaml_flambda/base-rev.txt] as the cache key, | |
| # given that it is updated when and only when we import new changes from | |
| # flambda-backend into merlin-jst. | |
