# Disable instrumentation in various external libraries. These
# are fuzzed elsewhere.
# The following disables both coverage-instrumentation and other sanitizer instrumentation.
# We disable instrumentation in:
# antlr4
# google_protobuf
# absl
# googltest
# grpc
# boringssl
# re2
# upb
# brotli
# cel_cpp
# yaml_cpp
# wasm_cpp_host
# libprotobuf-mutator
# google_url (gurl)
# lightstep_tracer
# In addition to this, we disable instrumentation in all *.pb.cc (protobuf-generated files)
# and everything in the bazel-out directory.
