            Bug ID: 36657
           Summary: lld-link needs to support /ignore:4037
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: COFF
          Assignee: unassignedbugs at nondot.org
          Reporter: nicolasweber at gmx.de
                CC: llvm-bugs at lists.llvm.org

link.exe emits lnk4037 if a symbol in an order file is not found in the program
(https://msdn.microsoft.com/en-us/library/aa234881(v=vs.60).aspx). lld-link
does too, but /ignore:4037 doesn't suppress the warning with lld-link.

In Chromium, we regenerate order files only now and then, so they usually
reference non-existing functions. We pass /ignore:4037 to the linker.

Since lld doesn't yet support /ignore:4037 we can't currently use order files
with lld-link.
