| # This filegroup is necessary because Bazel requires that every file in the .d |
| # file of a compilation action is in a subdirectory of one of the transitive |
| # dependencies of the rule being compiled. |
| # |
| # (this is not an intentional feature but accidentally results from the fact |
| # that lines in the .d files must be turned into Artifact instances and thus |
| # need a source root. See ArtifactFactory.findSourceRoot() for the pertinent |
| # logic) |
| # |
| # The easiest way to ensure this is to add this filegroup to one of the |
| # dependencies of the cc_toolchain. Then the root directory of the repository |
| # becomes part of said transitive dependencies and thus every file is in a |
| # subdirectory of it. |
