            Bug ID: 18728
           Summary: clang-cl balks on /d2Zi+
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: Driver
          Assignee: unassignedclangbugs at nondot.org
          Reporter: sami.liedes at redlynx.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

Using "Windows installer, based on SVN r199995".

clang-cl fails to either understand or ignore the (undocumented, but widely
used) /d2Zi+ flag, which adds useful debug info to optimized code.

I merely switched the toolset in an existing Visual Studio project to LLVM and
tried to build the project. The result contains errors like this:

2>clang-cl.exe : error : no such file or directory: '/d2Zi+'
