# RUN: lld -flavor darwin -arch i386 -r -print_atoms %s -o %t | FileCheck %s

# Test parsing of new __eh_frame (dwarf unwind) section that has no .eh labels
# and no relocations.

[macho] Create references from __eh_frame FDEs to their function. We'll also need references back to the CIE eventually, but for now making sure we can work out what an FDE is referring to is enough.
