A minimal compiler for the miniJava language, built as part of a compiler design course. It features a full pipeline: lexical analysis, parsing, AST generation, semantic analysis, IR generation, control flow graph generation, and bytecode interpretation.

• Lexical Analysis using Flex
• Parsing using Bison
• AST construction
• Semantic analysis with custom Symbol Table
• Intermediate Representation (IR) generation
• Control Flow Graph (CFG) output
• Bytecode generation and interpretation

• lexer.flex: Lexical analyzer (tokens)
• parser.yy: Parser (grammar rules)
• Node.h: AST structure and DOT generator
• symbolT.cc: Symbol table & semantic analysis
• IR.cc: IR generation and CFG creation
• interpreter.cc: Stack-based bytecode interpreter
• main.cc: Compiler driver
