Take the existing small footprint and mostly time invariant C code and turn it into a SM4 library that can be used for non-performance critical, casual use of SM4, and as a fallback for, e.g., SIMD code that needs a secondary path that can be taken in contexts where the SIMD unit is off limits. Secondly, some codes have been optimized, such as unrolling small times loop, removing unnecessary memory shifts, exporting sbox, fk, ck arrays, and basic encryption and decryption functions.
