How are compilers made

A compiler is likely to perform some or all of the following operations, often called phases: preprocessing, lexical analysis, parsing, semantic analysis ( syntax-directed translation ), conversion of input programs to an intermediate representation, code optimization and machine specific code generation.

Webmodern compilers, the most common intermediate form looks much like the MIPS instruction set but with an infinite number of virtual registers; later, we describe how to map these virtual registers to a finite set of real registers. Figure 2.12.2 shows how our example might be represented in such an intermediate form. WebCompilers have several disadvantages: Because the source code is translated as a whole, there must be enough memory space to hold the source code, the compiler and the generated object code.
