            Bug ID: 16796
           Summary: MCJIT/RuntimeDyld memory usage is inefficient.
           Product: libraries
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Generic Execution Engine Support
          Assignee: unassignedbugs at nondot.org
          Reporter: andrew.kaylor at intel.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

MCJIT and RuntimeDyld are currently fairly sloppy in their use of memory.
Several objects that are only needed during the compiling and loading phases
are kept in memory throughout the lifetime of the MCJIT engine. This makes use
of MCJIT prohibitively expensive on devices where memory is limited.
