             Bug #: 13383
           Summary: many clang options and warning flags undocumented
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Documentation
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: mayer.julian at googlemail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


i couldn't find documentation on these flags and warnings anywhere on the llvm
or clang website, in the clang manpage and in the clang --help section:


-fwrapv
-ftrapv
-Wbool-conversion
-Wshift-overflow
-Wliteral-conversion

please document all options. 
we also need a section that documents *all* warnings, probably with an extra
sections for warnings that are unique to clang.
