1 # Testing configuration for back-deployment against older Apple system libunwind.
3 # Under this configuration, we compile and link all the test suite against the latest libunwind,
4 # however we run against the libunwind on a different platform. This emulates the workflow of
5 # a developer building their application using recent tools but with the goal of deploying
6 # on existing devices running an older OS (and hence an older dylib).
