Comment:

 * [6:52pm] gabor: solution is this:
 https://github.com/ghc/ghc/blob/master/compiler/cmm/CmmPipeline.hs#L183
  * [6:52pm] gabor: splitting has to happen on PPC/ELF too
  * [6:54pm] Igloo: Could you send a patch please, including another "The
 situation is the same" section for PPC/ELF (or altering the existing ong
 if the asm is identical)
  * [6:54pm] Igloo: And thanks for tracking this down!
  * [7:01pm] gabor: Igloo: this is my first hunch, will test. But maybe
 PPC/ELF has actually consistent PIC-reg, in which case we have to dig
 deeper. But for now I'll go this route and check stuff later
  * [7:02pm] gabor: with domain experts (e.g. the LLVM list)
