◆ recordBlockInfo()

void CGOpenCLRuntime::recordBlockInfo	(	const BlockExpr *	E,

Record invoke function and block literal emitted during normal codegen for a block expression.

Record emitted llvm invoke function and llvm block literal for the corresponding block expression.

The information is used by emitOpenCLEnqueuedBlock to emit wrapper kernel.

Parameters

InvokeF	invoke function emitted for the block expression.
Block	block literal emitted for the block expression.
