The syntax analysis phase can detect errors where the token stream violates the structure rules of the language. During semantic analysis, the compiler tries to construct a right syntactic structure, but no. Conceptually, a compiler operates in phases, each of which transforms the source program from one representation to another In practice, some of the phases may be grouped together One can say that. Phases of Compilation A compiler can be broken into a front end and a back end Separating the front end from the back end enables code re-use.
Phases of a compiler are sub tasks that must be performed to complete the compilation process. Passes refers to the number of times the compiler has to traverse through the entire program.
