| ## Show that llvm-readobj/llvm-readelf tools sometimes can dump the |
| ## dynamic table when it is not in a PT_DYNAMIC segment. |
| |
| ## Case 1: The dynamic table found using the dynamic program header is corrupted |
| ## (<size of data> % <size of dynamic entry> != 0). So the table is taken |
| ## from the section header. |
