# Math functions not yet available in the libc project, or those not yet tuned
# for GPU workloads are provided as wrappers over vendor libraries. If we find
# them ahead of time we will import them statically. Otherwise, we will keep
# them as external references and expect them to be resolved by the user when
# they compile. In the future,we will use implementations from the 'libc'
# project and not provide these wrappers.
