//    T getX() { return X; }

// `llvm-objcopy --strip-dwo` strips out dwo sections, as a result, the index of 
// the symbol table, the indices of the symbols and the indices of the sections 
// which go after the removed ones will change. Consequently, the fields 
// Link, Info and the content of .group need to be updated. In the past 
// `llvm-objcopy --strip-dwo` used to produce invalid binaries with 
// broken .group section, this test verifies the correctness of 
// Link, Info and the content of this section.
