# Unconditionally adding in platform version flags will result in warnings that
# will be treated as errors by some packages. Add any missing flags here.
# There are two things to be configured: the "platform version" (oldest
# supported version of macos, ios, etc), and the "sdk version".
#
# The modern way of configuring these is to use:
# -platform_version $platform $platform_version $sdk_version"
#
# The old way is still supported, and uses flags like:
# -${platform}_version_min $platform_version
# -sdk_version $sdk_version
#
# If both styles are specified ld will combine them. If multiple versions are
# specified for the same platform, ld will emit an error.
#
# The following adds flags for whichever properties have not already been
# provided.

# empty due to being run through the cc-wrapper then the mangle here is a no-op
# and we still do the right thing.
