Detailed Description

A list of block predecessors.

The (returned) predecessor list is associated with the operation and block whose predecessors these are, and thus extends the lifetime of this operation and block.

WARNING: This Sliceable is more expensive than the others here because mlirBlockGetPredecessor actually iterates the use-def chain (of block operands) anew for each indexed access.
