Hi,
I'm trying to avoid CAF's being created, and I was wondering how is
the best way to do it with GHC. For example:
f = ....
Can I attach {-# INLINE #-} to f, and expect the CAF to be removed
that way? Is there any NOCAF annotation. I can always f _, then change
the callers to f () - if I'm doing that what is the most efficient
fake argument, and should I annotate f in any way? If the dummy
argument isn't used, is GHC going to float the let outside and re-CAF
it?
The next example is:
foreign import ccall safe "stdio.h getchar" getchar2 :: CInt
Can I stop this being CAF'd in any way?
I'm working at a very low level here, so any hacky things with big
disclaimers are still appreciated.
Thanks
Neil
