Member Enumeration Documentation

enum llvm::AliasAnalysis::PointerAccessInfo::AccessType

AccessType - Specific fine-grained access information for the argument. If none of these classifications is general enough, the getModRefBehavior method should not return AccessesArguments*. If a record is not returned for a particular argument, the argument is never dead and never dereferenced.

Enumerator:

ScalarAccess	ScalarAccess - The pointer is dereferenced.
ArrayAccess	ArrayAccess - The pointer is indexed through as an array of elements.
CallsThrough	ElementAccess ?? P->F only? CallsThrough - Indirect calls are made through the specified function pointer.

Member Data Documentation

ModRefResult llvm::AliasAnalysis::AliasAnalysis::PointerAccessInfo::ModRefInfo

ModRefInfo - Whether the pointer is loaded or stored to/from.

Value* llvm::AliasAnalysis::AliasAnalysis::PointerAccessInfo::V

V - The value this record corresponds to. This may be an Argument for the function, a GlobalVariable, or null, corresponding to the return value for the function.
