           Summary: Strange link warnings on Linux
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Target Description Classes
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: rspencer at x10sys.com


This has been happening consistently on Linux for a number of weeks now. I don't
really know what it is all about but I suspect it has to do with inlining. The
symbol is translated by c++filt as: 

llvm::TargetLowering::getValueType(llvm::Type const*) const

That function is defined in TargetLowering.h  and has a switch statement and an
assert. If this is an inlining problem then why don't we get this message all
over the place? 

Anyone got a clue on this?
