We are working on a substantial re-engineering of GHC's code generation, so this problem will eventually go away. But think "2008" not "Christmas 2007". Meanwhile does -fasm work?
There's no NCG for IA64, unfortunately. Unless someone writes one before 6.10, IA64 will be relegated to unregisterised compilation. Cheers, Simon
