| 32 | /* Normally, this uses | |
| 33 | ((xword - 0x0101010101010101) & 0x8080808080808080) test | |
| 34 | to find out if any byte in xword could be zero. This is fast, but | |
| 35 | also gives false alarm for any byte in range 0x81-0xff. It does | |
| 36 | not matter for correctness, as if this test tells us there could | |
| 37 | be some zero byte, we check it byte by byte, but if bytes with | |
| 38 | high bits set are common in the strings, then this will give poor | |
| 39 | performance. You can #define EIGHTBIT_NOT_RARE and the algorithm | |
| 40 | will use one tick slower, but more precise test | |
| 41 | ((xword - 0x0101010101010101) & (~xword) & 0x8080808080808080), | |
| 42 | which does not give any false alarms (but if some bits are set, | |
| 43 | one cannot assume from it which bytes are zero and which are not). | |
| 44 | It is yet to be measured, what is the correct default for glibc | |
| 45 | in these days for an average user. | |
