Compiler Design - Gate Smashers

LL(1). Know how to calculate First and Follow sets—this is a guaranteed marks-earner. Bottom-Up Parsers: LR(0), SLR(1), LALR(1), and CLR(1).

Pro Tip: Understand the relationship between these. For example, every SLR(1) grammar is also LALR(1) and CLR(1), but not vice versa. Syntax Directed Translation (SDT)

This is where most GATE questions come from. You need to master : compiler design gate smashers

Memorize the "Power Hierarchy" of parsers. Knowing that CLR is the most powerful and LR(0) is the least helps you eliminate options in MCQ questions instantly.

Producing the actual Assembly or Machine code. 2. High-Yield Topics for GATE Lexical Analysis & Finite Automata GATE loves to test your ability to count tokens. Remember: Keywords, Identifiers, Operators, and Constants are tokens. Comments and White spaces are NOT tokens. Pro Tip: Understand the relationship between these

Creating a platform-independent code (like 3-Address Code ). Code Optimization: Making the code faster and leaner.

Uses both synthesized and inherited attributes (evaluated left-to-right). Code Optimization The focus here is on efficiency. Be ready for questions on: Common Sub-expression Elimination Dead Code Elimination Loop Optimization (Code Motion, Strength Reduction) 3. The "Gate Smashers" Approach: Tips for Success To study effectively, follow these tactical steps: You need to master : Memorize the "Power

Checking grammar using Context-Free Grammars (CFG) and building a Parse Tree .
