# This script creates a list of data types where each type is followed
# by the C++ mangled name for that type. That list is then compared
# against the list in the c++-types.data file for the platform being
# checked. Any difference between the two would mean that the C++ ABI
# had changed and that should not happen even if the change is compatible
# at the C language level.
#
# The list of data types has been created with
