Ricardo Rocha 16c1056a01 tabling support for the common global trie is now available by default
(macro GLOBAL_TRIE was removed). Use 'yap_flag(tabling_mode,MODE)' to
set the storing mode for all tabled predicates to MODE ('local_trie' or
'global_trie). Alternatively, use 'tabling_mode(PRED,MODE)' to set the
default tabling mode of predicate PRED to MODE ('local_trie' or
'global_trie'). The default mode for all tabled predicates is 'local_trie'.
