Cpylier is a C Compiler written in Python.

1. Parsing & AST Generation
   • Reads source code
   • Generates Abstract Syntax tree
2. Semantic Analysis
   • Type checking & Scope Validation of AST
3. LLVM IR Generation
   • Converts AST to LLVM Intermediate Representation
   • Sets target triple dynamically.
4. User chosen Execution modes
   • JIT Execution - Runs IR directly with LLVM JIT
   • IR Output - Outputs IR
   • Clang Compilation - Compiles IR to executable

1. C Language features
   • Variables & Assignments
   • Conditionals
   • Loops
   • Function Calls
   • Structs & Pointers
   • C Standard Library
2. Backend Improvements
   • Generate ASM instead of IR
   • Custom x86_64 backend to replace Clang
3. IR Optimisations
   • Constant Folding
   • Dead Code Elmination
   • Loop Unrolling
   • Function Inlining
   • LLVM Optimsation Passes
4. Debugging/Error Handling
   • Syntax Error reporting
   • Semantic Error detection
   • AST Pretty-Printing
5. Ahead of Time Compilation
   • Custom Object File Generator
   • Customer Linker
6. Multi-File Compilation
   • Multiple files
   • Support include statements

1. Support variables, conditionals, loops
2. Improve error handling
3. Constant folding, dead code elmination
4. Multi-File Compilation
5. Assembler Backend
