GATE CSE 2023 | Question: 27
Consider the control flow graph shown. Which one of the following choices correctly lists the set of live variables at the exit point of each basic block? $\text{B1: { }, B2: {a}, B3: {a}, B4: {a}}$ $\text{B1: {i, j}, B2: {a}, B3: {a}, B4: {i}}$ $\text{B1: {a, i, j}, B2: {a, i, j}, B3: {a, i}, B4: {a}}$ $\text{B1: {a, i, j}, B2: {a, j}, B3: {a, j}, B4: {a, i, j}}$

Live Variable Analysis | Made Easy Full Syllabus Test
A variable v is live at a program point p if some path from p to program exit contains an r-value occurrence of v which is not preceded by an l-value occurrence of v . That is, the variable should be referenced before ... zero as from the exit point there are no such definitions, to begin with? This is the solution they have provided :
