| 2059 | * of these analysers in the order of the lower bit to |
| 2060 | * the higher bit. This ordering is very important. |
| 2061 | * An analyser will often add/remove other analysers, |
| 2062 | * including itself. Any changes to itself have no effect |
| 2063 | * on the loop. If it removes any other analysers, we |
| 2064 | * want those analysers not to be called anymore during |
| 2065 | * this loop. If it adds an analyser that is located |
| 2066 | * after itself, we want it to be scheduled for being |
| 2067 | * processed during the loop. If it adds an analyser |
| 2068 | * which is located before it, we want it to switch to |
| 2069 | * it immediately, even if it has already been called |
| 2070 | * once but removed since. |
| 2071 | * |
| 2072 | * In order to achieve this, we compare the analyser |
| 2073 | * list after the call with a copy of it before the |
| 2074 | * call. The work list is fed with analyser bits that |
| 2075 | * appeared during the call. Then we compare previous |
| 2076 | * work list with the new one, and check the bits that |
| 2077 | * appeared. If the lowest of these bits is lower than |
| 2078 | * the current bit, it means we have enabled a previous |
| 2079 | * analyser and must immediately loop again. |
