Unroll in a sentence as a verb

It is a bit unfortunate that you have to "unroll" your code to get the most out of Numba.

However this does put LuaJIT at an unfair advantage since it can unroll loops to its hearts' content, while gcc can't.

There are a few keys issues many C compilers seem to run into today:- Loop unroll identification is really bad.

This forces you to unroll all of your loops, and you generally end up with a giant state machine, with each state occupying a row and depending on the state of the previous row.

In short, you consider the boolean circuit of what you want to compute and transform it so that the inputs are keys necessary to unroll the computation, until getting the encrypted result.

If you unroll it into three separate loops, one that does dom modification, one that does dom measurement, and another that does modification, then you will drop the number of repaints from potentially 100s to just 2.

For example, ICC will unroll and turn a single-level loop with a very obvious body into streaming stores if the increment is "i++" but not if it is the constant "i+=1".- The register allocation problem has some subtelties.

A "Vector", if allowed to do it is separately compiled from a "Vector"[1] and this is what has given templates an uncanny power in C++ as a method of doing very powerful transformations of code, as used by libraries like Eigen to unroll very complex multiple-pass algorithms into a single fast loop.
