[antlr-interest] sematic analysis ?

[venkat medhaj]

Hi,

I am kinda new to antlr and I wonder how to perform symantic analysis using
the tool. I was able to generate the AST output for a small grammar and now
I want to check for the type check errors. For ex: if I have a statement
that looks something like

int a + b , I just have to make sure that both are of type int.

or if I define a twice in my input, then thats a redefine error. Can some
one give me some insight into this ?

Thanks,
