Topic notes
In GATE CS, this foundational topic tests grammar analysis, parsing techniques, and compiler phase interactions through both theoretical properties and computational mechanics. Questions frequently evaluate FIRST/FOLLOW set computation, LL(1) parsing table construction, LR parser capabilities, and bottom-up reduction steps. In addition, conceptual items regularly test front-end compiler phase responsibilities, phase inputs/outputs, and error detection stages.
