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).
Loop unrolling, dead code elimination, and constant folding. 💻 Phase 6: Code Generation Input: Optimized intermediate code. Output: Target Assembly or Machine Language. Task: Register allocation and instruction scheduling. 3. Key Technical Concepts for GATE compiler design gate smashers
In SSA, every variable is assigned exactly once. This forces the compiler to handle conditional assignments using . and CLR(1). Loop unrolling
A compiler translates high-level source code into low-level assembly or machine code through several distinct stages: Lexical Analysis (Scanning): dead code elimination
