| A list of |
| <code><a href="platform.html#constraint_value">constraint_value</a></code>s |
| that must be present in the target platform for this target to be considered |
| <em>compatible</em>. This is in addition to any constraints already set by the |
| rule type. If the target platform does not satisfy all listed constraints then |
| the target is considered <em>incompatible</em>. Incompatible targets are |
| skipped for building and testing when the target pattern is expanded |
| (e.g. `//...`, `:all`). When explicitly specified on the command line, |
| incompatible targets cause Bazel to print an error and cause a build or test |
| failure. |
| </p> |
| |
| <p> |
| Targets that transitively depend on incompatible targets are themselves |
| considered incompatible. They are also skipped for building and testing. |
| </p> |
| |
| <p> |
| An empty list (which is the default) signifies that the target is compatible |
| with all platforms. |
