            Bug ID: 39763
           Summary: Different linker option list behavior for empty or
                    single item list and list of multiple items.
           Product: clang
           Version: 7.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org

Steps to Reproduce:

test.ll:
!llvm.linker.options = !{!0}
!0 = !{}
or
!llvm.linker.options = !{!0}
!0 = !{!"one"}

command line:
clang test.ll

Actual Results:
warning: overriding the module target triple with x86_64-pc-linux-gnu
[-Woverride-module]
fatal error: error in backend: invalid llvm.linker.options
clang: error: clang frontend command failed with exit code 70 (use -v to see
invocation)
clang version 7.0.0-3 (tags/RELEASE_700/final)
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin
clang: note: diagnostic msg: PLEASE submit a bug report to
https://bugs.llvm.org/ and include the crash backtrace, preprocessed source,
and associated run script.
clang: note: diagnostic msg: Error generating preprocessed source(s) - no
preprocessable inputs.

But
!llvm.linker.options = !{!0}
!0 = !{!"one", !"two"}
is working.
