Two reasons: one, -O implies -fvia-C and two, -keep-hc-files also implies -fvia-C (because otherwise you don't get any .hc files). You'll need to modify the definition of GhcLibHcOpts in build.mk to put -fasm after -O, and also to remove -keep-hc-files.

I'll try this tonight, thanks.

BTW, am I the only one to find it alarming that GHC would allow conflicting options to override one another without any warning? :)

The GHC command-line isn't declarative, it's imperative. Options are processed left-to-right. That's the general rule, anyway. It would be an interesting exercise to specify the GHC command-line semantics, or better still, redesign it :) Cheers, Simon
