Microsoft PE/COFF Spec clearly states that the field is of signed interger type. However, in reality, it's unsigned. If cl.exe needs to create a large number of sections for COMDAT sections, it will just create more than 32768 sections. Handling large section number as negative number is not correct. I think this is a spec bug. Differential Revision: http://llvm-reviews.chandlerc.com/D3088 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203986 91177308-0d34-0410-b5e6-96231b3b80d8
