Joel,
YYSTYPE my_reportAmbiguity(YYSTYPE yyZ0, YYSTYPE yyZ1, ...)
...
Who writes print_reductions_func? What does it do precisely?
The intent is that my_reportAmbiguity be able to duplicate the functionality of yyreportAmbiguity, so it would be passed yyreportTree as a call back. The other parameters being those passed to yyreportAmbiguity. Of course developers could choose to print, or not, the tree in their own way, but they would have to export the necessary information.
At the moment, the tree underneath a yySemanticOption is resolved (destroyed in some sense) in a bottom-up fashion as the deferred semantic actions are performed and semantic values are produced. I'm not interested in trying to change this logic.
This is the bit I am tempted to have a go at. Stopping things happening is probably easier than making them happen. -- Derek M.
