* Parameters:
*
* SPH_KECCAK_64 use a 64-bit type
* SPH_KECCAK_UNROLL number of loops to unroll (0/undef for full unroll)
* SPH_KECCAK_INTERLEAVE use bit-interleaving (32-bit type only)
* SPH_KECCAK_NOCOPY do not copy the state into local variables
*
* If there is no usable 64-bit type, the code automatically switches
* back to the 32-bit implementation.
*
* Some tests on an Intel Core2 Q6600 (both 64-bit and 32-bit, 32 kB L1
* code cache), a PowerPC (G3, 32 kB L1 code cache), an ARM920T core
* (16 kB L1 code cache), and a small MIPS-compatible CPU (Broadcom BCM3302,
* 8 kB L1 code cache), seem to show that the following are optimal:
*
* -- x86, 64-bit: use the 64-bit implementation, unroll 8 rounds,
* do not copy the state; unrolling 2, 6 or all rounds also provides
* near-optimal performance.
* -- x86, 32-bit: use the 32-bit implementation, unroll 6 rounds,
* interleave, do not copy the state. Unrolling 1, 2, 4 or 8 rounds
* also provides near-optimal performance.
* -- PowerPC: use the 64-bit implementation, unroll 8 rounds,
* copy the state. Unrolling 4 or 6 rounds is near-optimal.
* -- ARM: use the 64-bit implementation, unroll 2 or 4 rounds,
* copy the state.
* -- MIPS: use the 64-bit implementation, unroll 2 rounds, copy
* the state. Unrolling only 1 round is also near-optimal.
*
* Also, interleaving does not always yield actual improvements when
* using a 32-bit implementation; in particular when the architecture
* does not offer a native rotation opcode (interleaving replaces one
* 64-bit rotation with two 32-bit rotations, which is a gain only if
* there is a native 32-bit rotation opcode and not a native 64-bit
* rotation opcode; also, interleaving implies a small overhead when
* processing input words).
*
* To sum up:
* -- when possible, use the 64-bit code
* -- exception: on 32-bit x86, use 32-bit code
* -- when using 32-bit code, use interleaving
* -- copy the state, except on x86
* -- unroll 8 rounds on "big" machine, 2 rounds on "small" machines
