2011-04-06RuntimeDyld should use the memory manager API.Jim Grosbach
Start teaching the runtime Dyld interface to use the memory manager API for allocating space. Rather than mapping directly into the MachO object, we extract the payload for each object and copy it into a dedicated buffer allocated via the memory manager. For now, just do Segment64, so this works on x86_64, but not yet on ARM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128973 91177308-0d34-0410-b5e6-96231b3b80d8
