# Cross task outputs can call native dependencies and even when cross
# recipe output doesn't change it might produce different results when

# contains symlink to clang binary from clang-native, but when clang-native
# outhash is changed, clang-cross-${TARGET_ARCH} will still be considered
# equivalent and target recipes aren't rebuilt with new clang binary, see
# work around in https://github.com/kraj/meta-clang/pull/1140 to make target
# recipes to depend directly not only on clang-cross-${TARGET_ARCH} but
# clang-native as well.
#
# This can cause poor interactions with hash equivalence, since this recipes
# output-changing dependency is "hidden" and downstream task only see that this
# recipe has the same outhash and therefore is equivalent. This can result in
# different output in different cases.
#
# To resolve this, unhide the output-changing dependency by adding its unihash
# to this tasks outhash calculation. Unfortunately, don't know specifically
# know which dependencies are output-changing, so we have to add all of them.
