Topic notes
Data flow analysis in GATE Compiler Design primarily evaluates an understanding of live variable analysis both conceptually and computationally on Control Flow Graphs (CFGs). Testing ranges from 1-mark recall questions on the compiler optimizations that rely on data-flow facts (like register allocation) to 2-mark CFG tracing questions tracking variable uses and definitions across program points.
