| // 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. |
