# target that doesn't support it will fail at compile time, not at runtime. This can
# be achieved by creating a `.verify.cpp` test that checks for the right errors, and
# mark that test as requiring `stdlib=<vendor>-libc++ && target=<target>`.
#
# Since it is not always known which deployment target to pick there are
# short-hands based on the LLVM version like using-built-library-before-llvm-xx.
# These short-hands make it easy for libc++ developers to select the proper
# version the feature will be available in and allows vendors to set the proper
# target information.
