Parameters

Name	Description
Loc	Memory location whose dependence is queried.
isLoad	True if the query is a load-like access.
ScanIt	Iterator to start scanning backwards from in `BB.`
BB	Basic block in which to scan for a dependence.
QueryInst	Optional instruction providing query metadata.
Limit	Optional remaining instruction scan budget; updated on return.
BatchAA	Batched alias analysis used for this query.
