dpiponi: Can you start by retrying with flags from the spectral-norm benchmark: http://shootout.alioth.debian.org/gp4/benchmark.php?test=spectralnorm&lang=ghc&id=0
Actually, that was my starting point for investigating how to optimise Haskell numerical code and I initially used all of those flags. -fvia-C isn't listed among those flags but I also tried adding it anyway. 1.45s every time, they make no difference. (And I made sure I touched the source each time to force recompilation.) It looks like my whole question might become moot with ghc 6.8.1, but so far I've been unable to build it due to the cyclic happy dependency. -- Dan
