986 | * for_all binding (computed during previous phase) | |
987 | * for_all C elements | |
988 | * match control flow of function vs minirule | |
989 | * with the binding and update the set of possible | |
990 | * bindings, and returned the possibly modified function. | |
991 | * pretty print modified C elements and reparse it. | |
992 | * | |
993 | * | |
994 | * On ne prends que les newbinding ou returned_any_state est vrai. | |
995 | * Si ca ne donne rien, on prends ce qu'il y avait au depart. | |
996 | * Mais au nouveau depart de quoi ? | |
997 | * - si ca donne rien apres avoir traité toutes les fonctions avec ce binding ? | |
998 | * - ou alors si ca donne rien, apres avoir traité toutes les fonctions | |
999 | * avec tous les bindings du round d'avant ? | |
1000 | * | |
1001 | * Julia pense qu'il faut prendre la premiere solution. | |
1002 | * Example: on a deux environnements candidats, E1 et E2 apres avoir traité | |
1003 | * la regle ctl 1. On arrive sur la regle ctl 2. | |
1004 | * E1 ne donne rien pour la regle 2, on garde quand meme E1 pour la regle 3. | |
1005 | * E2 donne un match a un endroit et rend E2' alors on utilise ca pour | |
1006 | * la regle 3. | |
1007 | * | |
1008 | * I have not to look at used_after_list to decide to restart from | |
1009 | * scratch. I just need to look if the binding list is empty. | |
1010 | * Indeed, let's suppose that a SP have 3 regions/rules. If we | |
1011 | * don't find a match for the first region, then if this first | |
1012 | * region does not bind metavariable used after, that is if | |
1013 | * used_after_list is empty, then mysat(), even if does not find a | |
1014 | * match, will return a Left, with an empty transformation_info, | |
1015 | * and so current_binding will grow. On the contrary if the first | |
1016 | * region must bind some metavariables used after, and that we | |
1017 | * dont find any such region, then mysat() will returns lots of | |
1018 | * Right, and current_binding will not grow, and so we will have | |
1019 | * an empty list of binding, and we will catch such a case. | |
1020 | * | |
1021 | * opti: julia says that because the binding is | |
1022 | * determined by the used_after_list, the items in the list | |
1023 | * are kind of sorted, so could optimise the insert_set operations. | |
