Detailed Description

SDValue - Unlike LLVM values, Selection DAG nodes may return multiple values as the result of a computation. Many nodes return multiple values, from loads (which define a token and a return value) to ADDC (which returns a result and a carry value), to calls (which may return an arbitrary number of values).

As such, each use of a SelectionDAG computation must indicate the node that computes it as well as which return value to use from that node. This pair of information is represented with the SDValue value type.

reachesChainWithoutSideEffects - Return true if this operand (which must be a chain) reaches the specified operand without crossing any side-effecting instructions. In practice, this looks through token factors and non-volatile loads. In order to remain efficient, this only looks a couple of nodes in, it does not do an exhaustive search.
