Introduction

The compiler works like a computer program used for transforming high-level language into a low-level language without modifying the meaning of a program.

In other words, it acts as an intermediate between machine-readable code and human-understandable language. The various operations that the compiler can perform are lexical analysis, semantic analysis, parsing, etc. The multiple operations consist of different inputs and outputs.

Types of Compiler

There exists a wide variety of compilers. Some of the common types of compilers are:
 

  1. Hardware Compiler: A compiler that produces output due to hardware configuration. Example: Xilinx Synthesis Tool (XST)
  2. Cross Compiler: A compiler that can produce source code in one machine and execute it on the other machine. Example: GNU Compiler Collection (GCC).
  3. JIT Compiler: This compiler is applicable for advanced programming languages such as python and java.
  4. Source to Source Compiler: A compiler that transforms the source code of one language into the source code of the other language. Example: Haxe

Compiler Design Architecture

The Compiler Design Architecture is divided into two main phases, namely:

  1. Analysis
  2. Synthesis

The diagrammatic representation for the Compiler Design Architecture is shown as:
 

Compiler Desgin Architecture

Analysis

This part mentions the front end of compiler design architecture. The various operations included in the phase are predicting the source code, dividing source code into multiple sections, and error analysis.

An intermediate program is taken into consideration as an output of this phase which is further sent for the synthesis scenario.

The various analysis phases are semantic analysis, syntax analysis, and lexical analysis.

Synthesis

This part mentions the back end of compiler design architecture. An intermediate program generated in the analysis phase is used as input for this particular phase.

The various synthesis phases are code generation and optimization.

Frequently Asked Questions

What is a compiler?

A computer program that converts high-level language into low-level language is called a compiler.

What is syntax analysis?

The phase in which the compiler checks the grammar of the programming.

What is a cross-compiler?

A compiler that produces source code on one machine and executes it on the other machine.

What is the full form of YACC?
