encodeCounter()

static unsigned encodeCounter ( ArrayRef< CounterExpression >  Expressions, Counter  C  )

static

Encode the counter.

The encoding uses the following format: Low 2 bits - Tag: Counter::Zero(0) - A Counter with kind Counter::Zero Counter::CounterValueReference(1) - A counter with kind Counter::CounterValueReference Counter::Expression(2) + CounterExpression::Subtract(0) - A counter with kind Counter::Expression and an expression with kind CounterExpression::Subtract Counter::Expression(2) + CounterExpression::Add(1) - A counter with kind Counter::Expression and an expression with kind CounterExpression::Add Remaining bits - Counter/Expression ID.
