Comment:

 I just sent this [http://www.haskell.org/pipermail/ghc-
 devs/2013-December/003531.html message] to the list characterizing the
 behavior of the NCG and LLVM backends in handling dynamic references. In
 short, the NCG and LLVM backends both handle intra-package references
 efficiently. That is, the branch I cited in comment 24 shouldn't be
 necessary.

 In this case, all we need is the fixes in this
 [https://github.com/bgamari/ghc/commits/llvm-dynamic branch] for
 functional dynamic linking with the LLVM backend. This has been tested on
 both x86_64 and ARM.
