As a last resort, with a Mach-O corefile, lldb will iterate through all memory segments looking for a dyld binary (for a userland process core dump) or an xnu kernel binary (kernel coredump). We often have metadata via LC_NOTEs so this final search mechanism is not needed. During the rewrite in https://reviews.llvm.org/D133680 I did not handle the case of finding the xnu kernel by exhaustive search correctly. rdar://103813200
