   Hello everyone,   
      
   i'm a University student and i've almost finished my first course of   
   abstract interpretation. i don't know much about data flow analysis   
   (DFA), and i'm wondering if it's worth of study it more in deep. (i my   
   compiler's course with treated the front-end part of the dragon book   
   only)   
      
   since someone says that nowadays it's better abstract interpretation   
   than DFA can anyone tell me what's the difference among them?  does   
   anybody know what kind of abstract int. (or DFA) techniques are used   
   in GCC and CLANG compiler?   
      
   some people say CLANG semantic analyzer is faster that GCC's one.   
   could this be related with the fact that CLANG's semantic checks are   
   weaker? anyway, how can clang be faster than gcc?   
      
   thank you!
