We should really use a C implementation of SHA1, the Haskell version

No, GHC won't be a native cross compiler in 6.12. There are #ifdefs
through the code which control what target architecture GHC is being
compiled for, and at the moment it doesn't support the host
architecture being different from the target architecture.
I did some work on the native
You can certainly create an array with these values, but in the provided code
it looks like each successive array element has a serial dependency on the
previous two elements. How were you expecting it to parallelise?
Repa arrays don't support visible destructive update. For many algorithms

No, I don't think anything extra is done in the native code generator
