Detailed Description

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.

Return true if this operand (which must be a chain) reaches the specified operand without crossing any side-effecting instructions.

reachesChainWithoutSideEffects - Return true if this operand (which must be a chain) reaches the specified operand without crossing any side-effecting instructions on any chain path.

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.

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.

Note that we only need to examine chains when we're searching for side-effects; SelectionDAG requires that all side-effects are represented by chains, even if another operand would force a specific ordering. This constraint is necessary to allow transformations like splitting loads.
