New description:

 LLVM backend does not work for PowerPC.

 From bug #5131 davidt says the order of business is:
 {{{
    a) Get unregistered working.
    b) Get registered without TABLES_NEXT_TO_CODE.
    c) Get TABLES_NEXT_TO_CODE working.
    d) Ask David where to go from there.
 }}}

 Actually there is now a guide of sorts
 [wiki:Commentary/Compiler/Backends/LLVM/GHC_LLVMPorting here].
