Member predicate SsaDefinition::getDefinition

Gets the control-flow node for this definition. This will usually be the control-flow node that assigns to this variable as a side effect, but there are some exceptions. If this is defined by initialization, the result is the value of Initializer.getExpr() for that initialization. If this is a function parameter (see definedByParameter), the result will be the function entry point. If this variable is defined by being passed as a reference in a function call, including overloaded operators, the result will be the VariableAccess expression for this parameter. If this is a phi node (see isPhiNode), the result will be the node where control flow is joined from multiple paths.
