Hi Xiao, > 1. In the tutorials, only klee_make_symbolic_name and klee_make_symbolic > are used, where can I find the other methods such as "klee_int" you > mentioned? Any documentation on how to use these methods? You can find the entire list of KLEE intrinsics, with comments, in include/klee/klee.h.

You should be able to simply ignore that directory when you aggregate coverage information.
