hasPathCrossingSuspendPoint()

bool llvm::SuspendCrossingInfo::hasPathCrossingSuspendPoint	(	BasicBlock *	From,
		BasicBlock *	To
	)		const

Returns true if there is a path from From to To crossing a suspend point without crossing From a 2nd time.

hasPathOrLoopCrossingSuspendPoint()

bool llvm::SuspendCrossingInfo::hasPathOrLoopCrossingSuspendPoint	(	BasicBlock *	From,
		BasicBlock *	To
	)		const

Returns true if there is a path from From to To crossing a suspend point without crossing From a 2nd time.

If From is the same as To this will also check if there is a looping path crossing a suspend point.
