| // 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. | |
