141 * hash a string into a long int. 31 bit crc (from andrew appel).
142 * the crc table is computed at run time by crcinit() -- we could
143 * precompute, but it takes 1 clock tick on a 750.
145 * This fast table calculation works only if POLY is a prime polynomial
146 * in the field of integers modulo 2. Since the coefficients of a
147 * 32-bit polynomial won't fit in a 32-bit word, the high-order bit is
148 * implicit. IT MUST ALSO BE THE CASE that the coefficients of orders
149 * 31 down to 25 are zero. Happily, we have candidates, from
150 * E. J. Watson, "Primitive Polynomials (Mod 2)", Math. Comp. 16 (1962):
151 * x^32 + x^7 + x^5 + x^3 + x^2 + x^1 + x^0
154 * We reverse the bits to get:
155 * 111101010000000000000000000000001 but drop the last 1
157 * 010010000000000000000000000000001 ditto, for 31-bit crc
