Public Attributes
mlir::Block *	optimisticBranchBlock = nullptr

	The destination index value.
cir::BrOp	initialBranch = {}
	The initial branch of the fixup.

Detailed Description

A branch fixup.

These are required when emitting a goto to a label which hasn't been emitted yet. The goto is optimistically emitted as a branch to the basic block for the label, and (if it occurs in a scope with non-trivial cleanups) a fixup is added to the innermost cleanup. When a (normal) cleanup is popped, any unresolved fixups in that scope are threaded through the cleanup.

destination

mlir::Block* clang::CIRGen::BranchFixup::destination = nullptr

The ultimate destination of the branch.

This can be set to null to indicate that this fixup was successfully resolved.

destinationIndex

unsigned clang::CIRGen::BranchFixup::destinationIndex = 0

The destination index value.

initialBranch

cir::BrOp clang::CIRGen::BranchFixup::initialBranch = {}

The initial branch of the fixup.

optimisticBranchBlock

mlir::Block* clang::CIRGen::BranchFixup::optimisticBranchBlock = nullptr

The block containing the terminator which needs to be modified into a switch if this fixup is resolved into the current scope.

If null, LatestBranch points directly to the destination.
