# UBSan vptr blacklist.
# Function and type based blacklisting use a mangled name, and it is especially
# tricky to represent C++ types. For now, any possible changes by name manglings
# are simply represented as wildcard expressions of regexp, and thus it might be
# over-blacklisted.
#############################################################################
# Identical layouts.
# If base and derived classes have identifical memory layouts (i.e., the same
# object size) and both have no virtual functions, we blacklist them as there
# would be not much security implications.
