Another bison problem

[Andrei Harangus]

Hy,

 

After solving the previous problem I would like to direct your attention to a more complicated one.

I am writing a rather large grammar that generates shift/reduce and reduce/reduce conflicts:

...

call : ID '(' call_list ')' {;}

call_list : expr ',' call_list

          | call ',' call_list

          | expr

          | call

;

 

expr : ...

     | call <-- HERE IT DOES

;

...

 

I know that the grammar is ambiguous, but I was wondering wether just by defining operator priorities

I could solve the problem (which I wasn't able to do), or I'll have to change the grammar

(and I don't know how).

 

Thanks,

Andrei
