| 1855 | * of these analysers in the order of the lower bit to |
| 1856 | * the higher bit. This ordering is very important. |
| 1857 | * An analyser will often add/remove other analysers, |
| 1858 | * including itself. Any changes to itself have no effect |
| 1859 | * on the loop. If it removes any other analysers, we |
| 1860 | * want those analysers not to be called anymore during |
| 1861 | * this loop. If it adds an analyser that is located |
| 1862 | * after itself, we want it to be scheduled for being |
| 1863 | * processed during the loop. If it adds an analyser |
| 1864 | * which is located before it, we want it to switch to |
| 1865 | * it immediately, even if it has already been called |
| 1866 | * once but removed since. |
| 1867 | * |
| 1868 | * In order to achieve this, we compare the analyser |
| 1869 | * list after the call with a copy of it before the |
| 1870 | * call. The work list is fed with analyser bits that |
| 1871 | * appeared during the call. Then we compare previous |
| 1872 | * work list with the new one, and check the bits that |
| 1873 | * appeared. If the lowest of these bits is lower than |
| 1874 | * the current bit, it means we have enabled a previous |
| 1875 | * analyser and must immediately loop again. |
