Look at the following expression( c-like syntax): 1 - 2 * (TYPE_OR_VAR) - 1
The real token type of TYPE_OR_VAR is unknown. The expression could be parsed as the following two options: 1. TYPE_OR_VAR is a typename. Then "(TYPE_OR_VAR)-1" is a cast expression. And the expression equals to: 1 - ( 2 * ( (TYPE_OR_VAR)-1)) 2. TYPE_OR_VAR is a variable. Then the expression equals to: 1 - 2 * TYPE_OR_VAR - 1 I would like to choose the second option but I can't do it with "%dprec". As when the ambiguity happens, the two options are shifted by the same rule. What can I do to get around this problem? _______________________________________________ help-bison@gnu.org http://lists.gnu.org/mailman/listinfo/help-bison
