# Bounds ignore list.
# Array at the end of struct pattern:
# Maybe UBSan itself can be improved here?
# e.g.
# struct blah {
#   int a;
#   char foo[2]; // not actually 2

# UBSan vptr ignore list.
# Function and type based ignorelisting 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-ignorelisted.

# UBSan seems to be emit false positives when virtual base classes are
# involved, see e.g. crbug.com/448102.

# UBsan goes into an infinite recursion when __dynamic_cast instrumented with
