Hi,
I get a lot of warnings in my project. Here is one excerpt of my grammar file:
stmtlist : stmt ';' { printf(".."); }
| stmtlist stmt ';' { printf(".."); }
;
1. line -> warning: unused value: $1
2. line -> warning: unused value: $2
The problem is that I don't want to use $1 and $2. Is there a better solution
to get rid of these warnings than to call Bison with "-Wno-other"???
I also get the warning that $$ is not set in some rules. How can I solve this
issue? Should I always set $$ to a value? What if I have rules which clean the
parsing stack and only perform some actions without modifying the stack. $$
always puts a new value on the parsing stack, right?
Cheers,
Bernd
