WebNon Operators (Bison 3.8.1) 5.3.6 Using Precedence For Non Operators Using properly precedence and associativity directives can help fixing shift/reduce conflicts that do not involve arithmetic-like operators. For instance, the “dangling else ” problem (see Shift/Reduce Conflicts) can be solved elegantly in two different ways. WebMay 17, 2014 · Bison can recognize two type of conflicts: shift/reduce: situation where a token can be shifted and a grammar rule can be reduced reduce/reduce: situation where two grammar rules can be reduced It is possible to instruct Bison to resolve shift/reduce and reduce/reduce conflicts when generating a parser.

WebSep 27, 2015 · There are three possible solutions to this problem: Do nothing. Bison does the right thing here, by design: it always prefers "shift" over "reduce".
