# Provides an implementation for _availability_version_check.
#
# This is required due to an upstream compiler builtin (runtime) change
# that marked this function as weakly-linked via __attribute__((weak import))
# As such, no linking failure occurs when the function is unavailable at
# link time. Since the symbol is no longer linked in, App Store review blocks
# publishing due to relying on a private symbol. Instead we link in our own
# implementation, which provides the exact implementation used in clang prior
# to the upstream change.
#
# See: Upstream clang change: https://reviews.llvm.org/D150397
# See: https://github.com/flutter/flutter/issues/133777
