| # Test parsing and writing of x86_64 text relocations. |
| # |
| # The first step tests if the supplied mach-o file is parsed into the correct |
| # set of references. The second step verifies relocations can be round-tripped |
| # by writing to a new .o file, then parsing that file which should result in |
| # the same references. |
