The grammar is as follows:
terminal TERM1,TERM2;
non terminal entry, sector, unit_a, unit_b;
entry ::= sector unit_b;
sector ::= unit_a sector | unit_a;
unit_a ::= TERM1 TERM1;
unit_b ::= TERM1 TERM2;
When i try to generate the parser with jcup, I'm getting the following warnings
Warning : *** Shift/Reduce conflict found in state #1
between sector ::= unit_a (*)
and unit_a ::= (*) TERM1 TERM1
under symbol TERM1
Resolved in favor of shifting.
Warning : *** Production "sector ::= unit_a " never reduced
How can i find what causes this conflict?
