Does your ghc-7.0.2 create 32 or 64 bit Code? What does "ghc --info" say?

As far as I know there was no 64bit ghc-6.12.x for MacOS. Is it possible 
to create a 64bit ghc starting with a 32Bit ghc? I don't think so and 
always used ghc-6.10.4 from macports to create 64bit binary-dists that 
have the suffix -x86_64-apple-darwin.tar.bz2 rather than 
-i386-apple-darwin.tar.bz2 for 32bit compilers.
