            Bug ID: 36456
           Summary: #pragma comment(lib) with relative path does not work
                    in LLD
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: COFF
          Assignee: unassignedbugs at nondot.org

We've got a case where a #pragma comment(lib...) directive is used in a
compilation unit, however with a relative path. Such as:

#define LIB_PATH "..\\..\\..\\..\\..\\extern\\OpenExr220\\lib\\" 
#pragma comment(lib, LIB_PATH "IlmImf-2_2.lib")

This works happily with link.exe, however lld doesn't like it and reports the
library as "not found". The path is relative to the compilation unit. I'm not
sure if link.exe uses that, or the fact that /LIBPATH: already specifies a path
to the correct lib.
