Hi guys, Is there a way to push, pop and peek into bison's semantic stack (i.e, manipulating the YYSTYPE variables, pushing custom ones) during the recognition of a rule? My goal is to build an AST during the rule matching phase and I need these tools for some special cases. I already did this (AST construction) but using a separate custom stack, I'm maintaining during the processing.. but now I would like to do that using the native bison stack..
Also, is it possible to define YYSTYPE to be a pointer on a structure instead of a union or a structure? I already tried that and just checked if it compiles fine and it was OK, however I didn't check the coherency of the whole recognition process. Best regards, Ilyes Gouta. _______________________________________________ help-bison@gnu.org http://lists.gnu.org/mailman/listinfo/help-bison
