# REQUIRES: x86

## 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.
