- * Include the PCLMUL/AVX implementation?  Although our PCLMUL-optimized CRC-32
- * function doesn't use any AVX intrinsics specifically, it can benefit a lot
- * from being compiled for an AVX target: on Skylake, ~16700 MB/s vs. ~10100
- * MB/s.  I expect this is related to the PCLMULQDQ instructions being assembled
- * in the newer three-operand form rather than the older two-operand form.
- *
- * Note: this is only needed if __AVX__ is *not* defined, since otherwise the
- * "regular" PCLMUL implementation would already be AVX enabled.
