Intermediate code generation is a phase in the compiler. In our earlier content \u2018Compiler in Computer<\/a>\u2019, we have discussed Intermediate code generation. It gets its input from the semantic analysis phase and serves its output to the code optimizer phase.<\/span><\/div>\n<\/div>\n

The intermediate code generator generates some intermediate representation. And from this intermediate representation, the compiler generates the target code.<\/span><\/div>\n<\/div>\n

    What is Intermediate Code Generation?<\/h3>\n
    \n
    As we know the task of the compiler is to process the source program and translate it into a target program. Well, in this process a compiler may generate one or more intermediate representations. This representation can have various forms.<\/span><\/div>\n
    The intermediate representation must be:<\/div>\n<\/div>\n

    2. Easy to translate into target code.<\/span><\/li>\n<\/ol>\n
      \n
      The intermediate representation can be of various forms. The two most important kinds of intermediate representations are:<\/span><\/div>\n<\/div>\n

      1. Tree i.e. \u201cparse trees\u201d and \u201csyntax tree\u201d.<\/span>
        <\/span><\/li>\n
      2. A Linear representation i.e., \u201cthree address code\u201d.<\/span><\/li>\n<\/ol>\n
        \n
        We have discussed \u201ctrees\u201d <\/span>briefly<\/span><\/span> in our previous content \u2018Syntax Directed Translation<\/a>\u2019. In this context, we will focus on the linear representation code i.e. “three address codes”.\u00a0<\/span><\/div>\n<\/div>\n

        Logical Structure of Compiler<\/h3>\n

        The logical structure of the compiler has two ends i.e., the front end and a back end. The front end generates the intermediate representation of the source program. And this intermediate representation helps the back end in generating the target program.<\/p>\n
