Detailed Description

This class represents a point being branched from in the methods of the RegionBranchOpInterface.

One can branch from one of two kinds of places:

• The parent operation (aka the RegionBranchOpInterface implementation)
• A region within the parent operation.

Constructor & Destructor Documentation

RegionBranchPoint() [1/4]

mlir::RegionBranchPoint::RegionBranchPoint ( Region *  region )

inline

Creates a RegionBranchPoint that branches from the given region.

The pointer must not be null.

Definition at line 206 of file ControlFlowInterfaces.h.

RegionBranchPoint() [2/4]

mlir::RegionBranchPoint::RegionBranchPoint ( Region &  region )

inline

Definition at line 210 of file ControlFlowInterfaces.h.

RegionBranchPoint() [3/4]

mlir::RegionBranchPoint::RegionBranchPoint ( std::nullptr_t  )

delete

Explicitly stops users from constructing with nullptr.

RegionBranchPoint() [4/4]

mlir::RegionBranchPoint::RegionBranchPoint ( RegionSuccessor  successor )

inline

Constructs a RegionBranchPoint from the the target of a RegionSuccessor instance.

Definition at line 217 of file ControlFlowInterfaces.h.

getRegionOrNull()

Region* mlir::RegionBranchPoint::getRegionOrNull ( ) const

inline

Returns the region if branching from a region.

A null pointer otherwise.

isParent()

bool mlir::RegionBranchPoint::isParent ( ) const

inline

Returns true if branching from the parent op.
