Comment(by vivian):
I've attached a patch for what I've done so far, it is not pretty.
Two recommendations after having done some coding:
1) Don't try and have dummy functions for CPUs that don't support specific
instructions, insist that the programmer do the checking that they are
using the right primOps. This is for efficiency and sanity.
2) There needs to be some CMM programming, for example to pack/unpack
scalar to vector, which require combinations of machine ops
