> And one more:
x = (x * mult) ^ t;
also appears to work equally well.
The order of operations does not really matter: you can write the loop as
x *= mult # Appears only in FNV-1
x ^= t[0]
x *= mult
x ^= t[1]
x *= mult
x ^= t[2]
x *= mult
x ^= t[3]
x *= mult # Appears only in FNV-1a
The initial multiplication is equivalent to changing the initial value and the
final multiplication is just a permutation of the outputs. None of those should
really affect the quality of the hash.
