conditionVar

const SVFVar* SVF::IntraCFGEdge::conditionVar

private

conditionVar is a boolean (for if/else) or numeric condition variable (for switch). branchCondVal is the value when this condition should hold to execute this CFGEdge. E.g., Inst1: br cmp label 0, label 1, Inst2: label 0 Inst3: label 1; for edge between Inst1 and Inst 2, the first element is cmp and the second element is 0
