Study Notes
Module-I: Formal Language and Regular Expressions
- Formal languages are defined using regular expressions
- Finite Automata is a mathematical model for recognizing regular expressions
- There are two types of Finite Automata: DFA (Deterministic Finite Automata) and NFA (Non-Deterministic Finite Automata)
- Conversion of regular expressions to NFA and NFA to DFA is possible
- Applications of Finite Automata include lexical analysis and lex tools
- Context-Free Grammars (CFG) are used to generate syntax of programming languages
- Parsing is the process of analyzing a string of symbols to determine its grammatical structure
- LL(K) and LL(1) grammars are types of CFGs used for parsing
Module-II: Bottom-up Parsing and Semantics
- Bottom-up parsing is a parsing technique that constructs a parse tree from an input string
- Handle pruning is a technique used to improve the efficiency of bottom-up parsing
- LR Grammar Parsing and LALR parsing are types of bottom-up parsing
- YACC (Yet Another Compiler Compiler) is a tool used to generate parsers
- Syntax-directed translation is a technique used to generate intermediate code
- S-attributed and L-attributed grammars are used to define the semantics of programming languages
- Abstract Syntax Trees (ASTs) are data structures used to represent the source code of a program
Module-III: Context-Sensitive Features
- The Chomsky Hierarchy is a classification of formal languages based on their power
- Type checking is a technique used to ensure the correctness of a program
- Type conversions and equivalence of type expressions are used to check the type safety of a program
- Overloading of functions and operations is a feature of programming languages
- Context-sensitive features are used to analyze the semantics of a program
Module-IV: Run-time Storage and Code Optimization
- Storage organization refers to the way a program's data is stored in memory
- Storage allocation strategies are used to manage memory allocation
- Scope and access control are used to manage the visibility of variables
- Code optimization is the process of improving the performance of a program
- Principal sources of optimization include redundancy elimination and strength reduction
- Peephole optimization and flow graphs are techniques used to optimize basic blocks
- Data flow analysis is used to analyze the flow of data in a program
Module-V: Code Generation
- Machine-dependent code generation is the process of generating code for a specific machine
- Object code forms are used to represent the target code
- Generic code generation algorithms are used to generate code for different machines
- Register allocation and assignment are used to optimize the use of registers
- DAG (Directed Acyclic Graph) representation of blocks is used to optimize the code generation process
