# SWIFT_ENABLE_TENSORFLOW
# NOTE: A non-empty `_Differentiation` module is currently created only on
# master branch, not on tensorflow branch.
#
# Instead, on tensorflow branch, the differentiation-related Swift source files
# in this directory are directly built as part of swiftCore: see
# stdlib/public/core/CMakeLists.txt. The `_Differentiation` module is created
# empty to enable `#if canImport(_Differentiation)` guards in tests.
