| ## If for some bizarre reason the input file defines its own ___dso_handle, we |
| ## should raise an error. At least, we've implemented this behavior if the |
| ## conflicting symbol is a global. A local symbol of the same name will still |
| ## take priority in our implementation, unlike in ld64. But that's a pretty |
| ## far-out edge case that should be safe to ignore. |
