# cert-*
#   -cert-dcl50-cpp
#     We use variadic functions
#   -cert-err58-cpp
#     GoogleTest creates instances in static scope in a way that trips this
#     warning for every test.
# readability-*
#   -readability-else-after-return
#   -readability-implicit-bool-conversion
#     These checks generate a bunch of noise that we're just not religious
#     about.
# modernize-*
#   -modernize-use-equals-default
#     VS 2015 and Xcode <= 8.2 don't fully support this so we don't use
#     `= default`.
#   -modernize-use-equals-delete
#     GoogleTest generates test classes that use the old idiom of making
#     default constructors and operator= private.
