Hi, I'm having shift/reduce conflict with the unary expression in my grammar
file. I've tried using the %prec modifier but it doesn't seem to work.
%token NUMBER
%token BIT_NOT NOT
%left PLUS MINUS OR XOR
%left UPLUS
%%
expression_list
: /* empty */
| expression_list summation_expression
;
summation_expression
:unary_expression
| summation_expression PLUS unary_expression
| summation_expression MINUS unary_expression
| summation_expression OR unary_expression
| summation_expression XOR unary_expression
;
unary_expression
: NUMBER
| PLUS NUMBER %prec UPLUS
| BIT_NOT NUMBER
| NOT NUMBER
;
I hope someone can help me with this. Thanks.
