Routines to test the hash are included ++if SELF_TEST is defined. You can use this free for any purpose. It's in ++the public domain. It has no warranty. ++ ++You probably want to use hashlittle(). hashlittle() and hashbig() ++hash byte arrays. hashlittle() is is faster than hashbig() on ++little-endian machines. Intel and AMD are little-endian machines. ++On second thought, you probably want hashlittle2(), which is identical to ++hashlittle() except it returns two 32-bit hashes for the price of one. ++You could implement hashbig2() if you wanted but I haven't bothered here. ++ ++If you want to find a hash of, say, exactly 7 integers, do ++ a = i1; b = i2; c = i3; ++ mix(a,b,c); ++ a += i4; b += i5; c += i6; ++ mix(a,b,c); ++ a += i7; ++ final(a,b,c); ++then use c as the hash value. If you have a variable length array of ++4-byte integers to hash, use hashword(). If you have a byte array (like ++a character string), use hashlittle(). If you have several byte arrays, or ++a mix of things, see the comments above hashlittle(). ++ ++Why is this so big? I read 12 bytes at a time into 3 4-byte integers, ++then mix those integers. This is fast (you can do a lot more thorough ++mixing with 12*3 instructions on 3 integers than you can with 3 instructions ++on 1 byte), but shoehorning those bytes into integers efficiently is messy. ++------------------------------------------------------------------------------- ++*/ ++ ++/* ++ * My best guess at if you are big-endian or little-endian.
