This exampe features a grammar showing both S/R and R/R conflicts.
The grammar produces 4 shift-reduce conflicts and 3 reduce-reduce conflicts.
By default, the S/R conflicts are solved using SHIFT, while the R/R conflicts
are solved using a reduction to the rule first mentioned in the grammar.
Notes on the output generated by bison.
Bison states:
grammar:7.5: warning: rule never reduced because of conflicts: E: i
However, this is probably incorrect considering its own documentation which
states the `first rule' preference in case of R/R conflicts.
Here is the grammar used in this example:
%token i
%%
E:
i
|
i
|
E '+' E
|
E '*' E
;
|
