Sure, I will file a ticket once I have more clarity on the problem. BTW, I forgot to mention that this is with ghc-7.10.3. I will try to see how things stand with 8.0.1 at the assembly level though I have not seen any difference in the benchmark performance. I guess it is better to work off 8.0.1 anyway since things might have changed significantly.

hopefully, and you already did some great analysis. But sometimes
things are moving slow, so if nobody picks it up right away (I think
think the number of people who know the register allocator is rather
small), make sure you record your findings in a trac ticket, so that
they are not lost.

Greetings,
