aliasesPointer()

AliasResult AliasSet::aliasesPointer	(	const Value *	Ptr,
		LocationSize	Size,
		const AAMDNodes &	AAInfo,

	)		const

If the specified pointer "may" (or must) alias one of the members in the set return the appropriate AliasResult.

aliasesPointer - If the specified pointer "may" (or must) alias one of the members in the set return the appropriate AliasResult.

Otherwise return NoAlias.
