insertAfterInvokes()

std::pair< bool, bool > BundledRetainClaimRVs::insertAfterInvokes	(	Function &	F,
		DominatorTree *	DT )

Insert a retainRV/claimRV call to the normal destination blocks of invokes with operand bundle "clang.arc.attachedcall".

If the edge to the normal destination block is a critical edge, split it.
