           Summary: alignment on malloc instruction is not codegened
                    correctly
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Common Code Generator Code
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: alenhar2 at uiuc.edu


the backends (including C and x86) do not respect alignment on malloc.  consider
test/Features/alignment.ll.  The final malloc (%T) should be codegened to a
memalign to preserve the alignment.

Once this is done, all memalign and posix_memalign calls can be safely
transformed into llvm malloc instructions.  Plus it is just broken right now.
