Topic notes
In GATE CS, Intermediate Code Generation (ICG) is tested through both theoretical/architectural concepts and precise algorithmic computations. Core recurring topics include Static Single Assignment (SSA) form variable counting and renaming, basic block partitioning via leader identification, register allocation on expression trees (Sethi-Ullman / Ershov labeling), array address calculation in 3-address code, and IR structures (Triples, AST, CFG, backpatching). The topic maintains an even split between 1-mark conceptual questions and 2-mark procedural NAT/MCQ problems.
