Warnings by compilation

[Abramov, Evgenia]

Hi,

 

We use bison-2.0 and while compilation of the bison-generated code we receive the following warnings:

 

Compiling...
SystemVerilog.cpp
.\Debug/SystemVerilog.cpp(10567) : warning C4065: switch statement contains 'default' but no 'case' labels
.\Debug/SystemVerilog.cpp(10601) : warning C4065: switch statement contains 'default' but no 'case' labels
.\Debug/SystemVerilog.cpp(24526) : warning C4102: 'yyerrorlab' : unreferenced label

 

 

How it is possible to avoid the above warnings?

 

Thanks,

Genia
