Hi all,

I have noticed that there is a great difference between optimizing
modules separately and all at once, e.g., with -fforce-recomp. I have
had examples factors up to 15 in run time (and even different behavior
in context with unsafePerformIO).

Is there any option that makes ghc write out that intermediate
optimization data he seems to use in order to get the same efficiency in
a module-wise compilation?

Greetings
Bernd
