示例1: addParameterValuesToBindings
static void addParameterValuesToBindings(const StackFrameContext *CalleeCtx,

SValBuilder &SVB,
const CallEvent &Call,

// If the function has fewer parameters than the call has arguments, we simply
// do not bind any values to them.
unsigned NumArgs = Call.getNumArgs();
