// 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.
