You should show why deep access is better than shallow access from a programmer's perspective and not rely just on performance arguments.

Let's start with a brief overview of the compiler and then go on to the testability advice.

In your opinion, VLIW or superscalar, which paradigm presents greater difficulty for compilers? Why? Let's check out the compiler's suggested approach to testing and see how it performs. Let's have a look at the compiler's testability recommendation and put it through its paces.

Explain the idea of testability in further detail, and if it's not too much difficulty, give us a high-level overview of the compiler.
