| 397 | // A generalization of the best bit counting method to integers of |
| 398 | // bit-widths up to 128 (parameterized by type T) is this: |
| 399 | // |
| 400 | // v = v - ((v >> 1) & (T)~(T)0/3); // temp |
| 401 | // v = (v & (T)~(T)0/15*3) + ((v >> 2) & (T)~(T)0/15*3); // temp |
| 402 | // v = (v + (v >> 4)) & (T)~(T)0/255*15; // temp |
| 403 | // c = (T)(v * ((T)~(T)0/255)) >> (sizeof(T) - 1) * BITS_PER_BYTE; // count |
| 404 | // |
| 405 | // For comparison, for 32-bit quantities, this algorithm can be executed |
| 406 | // using 20 MIPS instructions (the calls to LoadConst32() generate two |
| 407 | // machine instructions each for the values being used in this algorithm). |
| 408 | // A(n unrolled) loop-based algorithm requires 25 instructions. |
| 409 | // |
| 410 | // For a 64-bit operand this can be performed in 24 instructions compared |
| 411 | // to a(n unrolled) loop based algorithm which requires 38 instructions. |
| 412 | // |
| 413 | // There are algorithms which are faster in the cases where very few |
| 414 | // bits are set but the algorithm here attempts to minimize the total |
| 415 | // number of instructions executed even when a large number of bits |
