16# NOTE(piman): This test will not work with other generators because:
17# - it explicitly tests the optimization, which is not implemented (yet?) on
18# other generators
19# - it relies on the exact path to output object files, which is generator
20# dependent, and actually, relies on the ability to build only that object file,
21# which I don't think is available on all generators.
22# TODO(piman): Extend to other generators when possible.
