- * OpenSSL-specific implementation notes.
- *
- * WHIRLPOOL_Update as well as one-stroke WHIRLPOOL both expect
- * number of *bytes* as input length argument. Bit-oriented routine
- * as specified by authors is called WHIRLPOOL_BitUpdate[!] and
- * does not have one-stroke counterpart.
- *
- * WHIRLPOOL_BitUpdate implements byte-oriented loop, essentially
- * to serve WHIRLPOOL_Update. This is done for performance.
- *
- * Unlike authors' reference implementation, block processing
- * routine whirlpool_block is designed to operate on multi-block
- * input. This is done for performance.

- * Note that every Cn macro expands as two loads: one byte load and

- * is too excessive, as one could load a quadword and "milk" it for
- * eight 8-bit values instead. Well, yes, but in order to do so *and*
- * avoid excessive loads you have to accommodate a handful of 64-bit
- * values in the register bank and issue a bunch of shifts and mask.
- * It's a tradeoff: loads vs. shift and mask in big register bank[!].
- * On most CPUs eight single-byte loads are faster and I let other
- * ones to depend on smart compiler to fold byte loads if beneficial.
- * Hand-coded assembler would be another alternative:-)
