The linker searches for defined modules in a program and finds out the memory location where all modules are stored. Linker: It links and merges a variety of object files into a single file to make it executable. This can be loaded at any point in time and can be run. Relocatable Machine Code: This enables the movement of a program using its unique address identifier. Another difference is, Interpreted programs are usually slower with respect to compiled ones.
#COMPILER DESIGN COURSES CODE#
The major difference between both is that the interpreter reads and transforms code line by line while Compiler reads the entire code at once and outputs the machine code directly. Interpreter: An interpreter converts high-level language into low-level machine language almost similar to what Compiler does. The output of an assembler is known as an object file which is a combination of machine instruction along with the data required to store these instructions in memory. Each platform (OS + Hardware) has its own assembler. It removes all the #include directives by including the files called file inclusion and all the #define directives using macro expansion.Īssembler: This translates assembly language code into machine understandable language. Pre-Processor: This produces input for the compiler and also deals with file inclusion, augmentation, macro-processing, language extension, etc. They tell the pre-processor about what to do. The (#) tags are referred to as preprocessor directives. They are closer to humans language but far from machines. High-Level Language: These are programs that contain #define or #include directives such as #include or #define.
Multi-Pass Compiler: This is a type of compiler that processes the source code or abstract syntax tree of a program multiple times before translating it to machine language. Two-Pass Compiler: This goes through the code to be translated twice on the first pass it checks the syntax of statements and constructs a table of symbols, while on the second pass it actually translates program statements into machine language. For instance, Pascal programming language. Single Pass Compiler: This directly transforms source code into machine code. Source-to-source Compiler: This can be referred to as a transcompiler or transpiler and it is a compiler that translates source code written in one programming language into source code of another programming language. For instance, it runs on a machine 'A' and produces code for another machine 'B'. Types of Compiler:Ĭross Compiler: This enables the creation of code for a platform other than the one on which the compiler is running. When executing, the compiler first analyzes all the language statements one after the other syntactically and then, if it's successful, builds the output code, making sure that statements that refer to other statements are referred to appropriately, Traditionally, the output code is called Object Code. The compiler process runs through syntax, lexical and semantic analysis in the front end and generates optimized code in the back end. The Compiler also makes the code output efficient and optimized for execution time and memory space. The compiling process has basic translation mechanisms and error detection, it can't compile code if there is an error. It essentially translates the code written in one programming language to another language without changing the logic of the code.

What is Compiler Design?Ĭompiler Design is the structure and set of principles that guide the translation, analysis and optimization process of a compiler.Ī Compiler is computer software that transforms program source code which is written in a high-level language into low-level machine code.
