Comment(by carter):

 It looks like head builds / bootstraps via llvm fine as long as stage 2
 and the libs aren't optimized.

 When I did the "quick llvm" build against head and the libs as of
 yesterday, I had the segfault build failure for stage 2 as I reported in
 the other ticket  http://hackage.haskell.org/trac/ghc/ticket/7874. the
 only difference between that and the sucessful build was that the
 libraries were build with -O rather than -O0.  So it might be a linker
 related issue that only happens when the llvm build is doing optimization?

 I'll do a test build at that finger print state in the next day or so
 after I get some other work done.
