Compiler design i aboutthetutorial a compiler translates the codes written in one language to some other language without changing the meaning of the program.
A compiler is a software program that transforms highlevel source code that is written by a developer in a highlevel programming language into a low level object code binary code in machine language, which can be understood by the processor. It enables a computer to be able to read different source codes. A phase is a logically interrelated operation that takes source program in one representation and produces output in another representation. For example, a compiler that runs on a windows 7 pc but generates code that runs on android smartphone is a cross compiler. It uses the same operating system or platform as the software for which it is assembling machine language. The pcodes for the pcode compiler would then be assembled by this system to give another cross compiler figure 3. Analysis phase creates an intermediate representation from the given source code.
