Avoid generating dead functions #69

Open jxyang opened 5 years ago

Dead functions are the ones never got called. Csmith occasionally generates them, giving compilers (and Creduce) an easy pass. It is generally bad when the generated code are not exercising the compilers.

FWIW, It's actually not as bad as it appears to be, e.g. EMI exploits dead code to find many wrong code bugs. I think it may be better to maintain certain level of dead code in the generated programs.
