Each phase transforms the source program from one representation to another. Six phases:
- Lexical Analyser
- Syntax Analyser
- Semantic Analyser
- Intermediate code generation
- Code optimization
- Code Generation
• Symbol table and error handling interact with the six phases.
• Some of the phases may be grouped together.
In Compiler there is no design word ,whereas in compiler design there is design word
Principles of Compiler Design was created in 1977.

There are two types of compilers one-pass and multi-pass. Pass means that some of inner operations are repeated several times. If we have one-pass compiler and this source code: i++; i++; i++; Inside compiler it would generate: i = i + 1; i = i + 1; i = i + 1; If compiler would be two-pass: i = i + 3; The more passes compiler has, the better optimized code it can generate, but it is slower because it must repeat some steps again.
