For several years now, GHC has had a native code generator (NCG),

desactivated (can some gurus explain why?...), and the first thing
I do with, is its recompilation. Such nasties as above become
then less dangerous.
The newer STG Hugs which we are developing has "real" Doubles as
When I have an -fasm-x86 and an -fvia-C in the command line,
which one is supposed to take precedence? Shouldn't (at the
moment) -fvia-C always take precedence, because it can't
hurt to compile via C?
I agree -fvia-C should take precedence. I'm not sure what

Folks,
The adventurous among you may like to try an innovation
which in some cases nearly doubles the speed at which
ghc compiles programs. This innovation is our native code
generator, which has long been in the GHC source tree,
but has only just been made to work for x86. It reduces

made this page, though. Anybody know who/where
