// `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.
