- * _c_mix -- Mix 3 32-bit values reversibly.
- *
- * For every delta with one or two bit set, and the deltas of all three
- * high bits or all three low bits, whether the original value of a,b,c
- * is almost all zero or is uniformly distributed,
- * If _c_mix() is run forward or backward, at least 32 bits in a,b,c
- * have at least 1/4 probability of changing.
- * If _c_mix() is run forward, every bit of c will change between 1/3 and
- * 2/3 of the time.  (Well, 22/100 and 78/100 for some 2-bit deltas.)
- * _c_mix() was built out of 36 single-cycle latency instructions in a 
- * structure that could supported 2x parallelism, like so:
- *     a -= b;
- *     a -= c; x = (c>>13);
- *     b -= c; a ^= x;
- *     b -= a; x = (a<<8);
- *     c -= a; b ^= x;
- *     c -= b; x = (b>>13);
- *     ...
- *
- * Unfortunately, superscalar Pentiums and Sparcs can't take advantage
- * of that parallelism.  They've also turned some of those single-cycle
- * latency instructions into multi-cycle latency instructions.  Still,
- * this is the fastest good hash I could find.  There were about 2^^68
- * to choose from.  I only looked at a billion or so.

- * _c_mix64 -- Mix 3 64-bit values reversibly.
- *
- * _c_mix64() takes 48 machine instructions, but only 24 cycles on a superscalar
- * machine (like Intel's new MMX architecture).  It requires 4 64-bit
- * registers for 4::2 parallelism.
- * All 1-bit deltas, all 2-bit deltas, all deltas composed of top bits of
- * (a,b,c), and all deltas of bottom bits were tested.  All deltas were
- * tested both on random keys and on keys that were nearly all zero.
- * These deltas all cause every bit of c to change between 1/3 and 2/3
- * of the time (well, only 113/400 to 287/400 of the time for some
- * 2-bit delta).  These deltas all cause at least 80 bits to change
- * among (a,b,c) when the _c_mix is run either forward or backward (yes it
- * is reversible).
- * This implies that a hash using _c_mix64 has no funnels.  There may be
- * characteristics with 3-bit deltas or bigger, I didn't test for
- * those.
