This early-access version of cuFFT previews LTO-enabled callback routines that leverages Just-In-Time Link-Time Optimization (JIT LTO) and enables runtime fusion of user code and library kernels.

cuFFT EA adds support for callbacks to cuFFT on Windows for the first time. On Linux, these new and enhanced LTO-enabed callbacks offer a significant boost to performance in many callback use cases.
