A search for "loop jamming" (also called fusion) in AltaVista,
"The idea is to combine adjacent loops which loop over the same range of
the same variable."
"If there are two loops with no data dependencies adjacent to one
another, push them together."
"Programmers often encounter two or more independent, vectorizable loops
with the same iteration count. By combining two or more of these loops
into one vector loop, loop control overhead can be reduced."
