示例1: aliasesPointer
/// aliasesPointer - Return true if the specified pointer "may" (or must)
/// alias one of the members in the set.
///
bool AliasSet::aliasesPointer(const Value *Ptr, unsigned Size,
AliasAnalysis &AA) const {
if (AliasTy == MustAlias) {

// If this is a set of MustAliases, only check to see if the pointer aliases
// SOME value in the set...

return AA.alias(SomePtr->first, SomePtr->second.getSize(), Ptr, Size);

// If this is a may-alias set, we have to check all of the pointers in the set
// to be sure it doesn't alias the set...
for (iterator I = begin(), E = end(); I != E; ++I)
