[cfe-dev] Return type of statement

[Ted Kremenek]

Alexei,

Statements that evalute to a value are known as expressions.   
Expressions are represented by the Expr class (which subclasses  
Stmt).  The method Expr::getType() will return the information you  
want.  I recommend looking at the Clang sources for example uses of  
this method.
