Welcome to the compilers tutorial! This section will guide you through the basics of compilers, including their role in programming, the different types of compilers, and their inner workings.
What is a Compiler?
A compiler is a program that translates source code written in one programming language into another language. The most common translation is from a high-level programming language into machine code, which can be executed directly by the computer's hardware.
Why Use a Compiler?
- Translation: Compilers enable the conversion of human-readable code into machine-readable code.
- Efficiency: Machine code is typically more efficient than interpreted code, leading to faster execution.
- Abstraction: High-level languages allow developers to write code at a higher level of abstraction, making programming more accessible.
Types of Compilers
There are several types of compilers, each with its own characteristics:
- Single-Pass Compiler: Processes the source code in a single pass, translating one statement at a time.
- Multi-Pass Compiler: Processes the source code in multiple passes, allowing for more complex analysis and optimization.
- Just-In-Time Compiler (JIT): Translates code at runtime, allowing for optimization based on actual usage patterns.
Compiler Phases
The process of compiling source code into machine code typically involves several phases:
- Lexical Analysis: Splits the source code into tokens.
- Syntax Analysis: Checks the structure of the code based on the grammar of the programming language.
- Semantic Analysis: Ensures that the code makes sense semantically, checking for type compatibility, variable declarations, etc.
- Intermediate Code Generation: Produces an intermediate representation of the source code.
- Code Optimization: Improves the intermediate code for better performance.
- Code Generation: Translates the optimized intermediate code into machine code.
