Detailed Description

Value representing pointer-to-member.

This value is qualified as NonLoc because neither loading nor storing operations are applied to it. Instead, the analyzer uses the L-value coming from pointer-to-member applied to an object. This SVal is represented by a DeclaratorDecl which can be a member function pointer or a member data pointer and a list of CXXBaseSpecifiers. This list is required to accumulate the pointer-to-member cast history to figure out the correct subobject field.
