1.8 Organization of the Compiler

The C compilation system consists of a compiler, an assembler, and a link editor. The cc command invokes each of these components automatically unless you use command-line options to specify otherwise.

Table A–15 discusses all the options available with cc.

The following figure shows the organization of the C compilation system.
