Detailed Description

Code generation module for KCC compiler.

Author

KCC Development Team

Version

1.10.0

Date

2024

This module implements code generation for the KCC compiler, supporting multiple target architectures (ARM64 and x86-64). It translates Abstract Syntax Tree (AST) nodes into native assembly code for the target platform.

Architecture Support

• ARM64 (Apple Silicon): Modern ARM 64-bit architecture
• x86-64 (Intel/AMD): Traditional 64-bit x86 architecture

The code generator automatically detects the target architecture at compile time and generates appropriate assembly code using platform-specific instructions, registers, and calling conventions.

Features

• Multi-architecture code generation
• Function call support with proper calling conventions
• Arithmetic and logical operations
• Control flow (if/else, loops)
• Variable storage and retrieval
• Label generation for jumps and branches

Usage Example

// Create code generator
CodeGenerator *codegen = codegen_create("output.s");
 
// Generate code from AST
if (codegen_generate(codegen, ast_root)) {
    printf("Code generation successful\n");
}
 
// Clean up
codegen_destroy(codegen);
