> We can use a maximum of 64-bit registers *unless* we use bigint. 

scalar instructions DESIGNED to accelerate bigint operations. 

see svfixedarith.

these are ***SCALAR** instructions.

they are NOT repeat NOT vector instructions.

the whole purpose of this grant is to design SCALAR instructions
*AND* to design a vector-looping-system that can take advantage
of those SCALAR instructions.

we found that maddedu was really damn good when auto-looped by SVP64.

but this task "actually shows and proves it".  if it *doesn't* do
that then we work out *why*, go back to the drawing board and
*design sclar instructions that do*.

this is how it works.
