            Bug ID: 50186
           Summary: Linker creates invalid executables that crash dyld
                    when linking Intel IPP
           Product: lld
           Version: unspecified
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: MachO
          Assignee: unassignedbugs at nondot.org

I'm trying lld 12 for macOS and can link and run trivial executables.  However
when I move on to another (unfortunately proprietary) codebase the generated
executables cause the following error from dyld:

dyld: REBASE_OPCODE_SET_SEGMENT_AND_OFFSET_ULEB has segment 0 which is not a
writable segment (__TEXT) in dist/lib/libxyz.dylib.1

It's worth noting that libxyz is static linked against Intel's IPP which I'm
guessing has a slightly different object format, since I think it's compiled
with ICC.

I am using clang with the -fuse-ld=lld.darwinnew option.
