My understanding is that the main problem is translating from Haskell to LLVM IR is a lossy process, not the difference between LLVM 2.8 and LLVM 3.4. This blog post demonstrates one such issue: http://blog.omega-prime.co.uk/?p=135 http://blog.omega-prime.co.uk/?p=135 Quote: "In particular, LLVM conservatively assumes that GHC's stack and the heap may alias". LLVM has to assume that short of Haskell-specific analysis, so updating to LLVM 3.4 won't help with such issues.
