I'm writing a perl module that interfaces some haskell code and its a bit of a
pain because both perl and ghc have their own custom build system.
Is there a way to get ghc to give you the gcc/as/ld options (library paths,
include paths, flags, etc) required for the FFI stub files it generates?
I tried out some of the vector and uvector fusion benchmarks with the
new LLVM backend

and got some great results for the tight loops generated through fusion.
Up to 2x faster than gcc -O3 in some

I suspect (just guessing...) that a more reliable way to find out is to

Just as a data-point, my code rarely exceeds 128 bits (at least, beyond
that performance isn't so important any

I think opinions are divided on this.
Performance with word-sized Integer's is definitely important.
This is true.
We could start
