Class IRBlockBase

A basic block in the IR. A basic block consists of a sequence of Instructions with the only incoming edges at the beginning of the sequence and the only outgoing edges at the end of the sequence.

This class does not contain any members that query the predecessor or successor edges of the block. This allows different classes that extend IRBlockBase to expose different subsets of edges (e.g. ignoring unreachable edges).

Most consumers should use the class IRBlock.
