             Bug #: 13073
           Summary: Trunk clang not working on arm
           Product: clang
           Version: trunk
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: -New Bugs
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: scoopr at iki.fi

    Classification: Unclassified


With trunk llvm and clang from few days ago,
the resulting clang doesn't seem to even compile hello world on armv6 linux,
debian squeeze.

This is a raspberry pi, with slightly slow SD card, so a full llvm+clang
rebuild took a about 24hours, so no quick testing..

The resulting error message from hello world compilation:
