Optimisations for Loops,Since programs tend to spend most of their time in loops, it is worthwhile to study optimisations specific for loops. We will in this chapter look at three specific optimisations for loops: ., which moves loop-invariant code out of a loop, ., which improves cache utilisation, and ., which replaces multiplication in a loop by addition.

Intermediate-Code Generation,ave to be expressed as machine code that can run on the computer. This does not mean that we need to translate directly from the high-level abstract syntax to machine code. Many compilers use a medium-level language as a stepping-stone between the high-level language and the very low-level machine code. Such stepping-stone languages are called ..

Lexical Analysis,, it will filter out whatever separates the tokens (the so-called .), i.e, lay-out characters (spaces, newlines etc.) and comments. For lexical analysis, specifications are traditionally written using .: An algebraic notation for describing sets of strings. The generated lexers are in a class of ext

Interpretation,ecutes it by inspecting the syntax tree to see what needs to be done. This is similar to how a human evaluates a mathematical expression: We insert the values of variables in the expression and evaluate it bit by bit, starting with the innermost parentheses and moving out until we have the result of
