◆ BaseSet
◆ IMAKind
| Enumerator | |
|---|---|
| IMA_Static | The reference is definitely not an instance member access. |
| IMA_Mixed | The reference may be an implicit instance member access. |
| IMA_Mixed_StaticOrExplicitContext | The reference may be to an instance member, but it might be invalid if so, because the context is not an instance method. |
| IMA_Mixed_Unrelated | The reference may be to an instance member, but it is invalid if so, because the context is from an unrelated class. |
| IMA_Instance | The reference is definitely an implicit instance member access. |
| IMA_Unresolved | The reference may be to an unresolved using declaration. |
| IMA_Abstract | The reference is a contextually-permitted abstract member reference. |
| IMA_Dependent | Whether the context is static is dependent on the enclosing template (i.e. in a dependent class scope explicit specialization). |
| IMA_Unresolved_StaticOrExplicitContext | The reference may be to an unresolved using declaration and the context is not an instance method. |
| IMA_Field_Uneval_Context | |
| IMA_Error_StaticOrExplicitContext | All possible referrents are instance members and the current context is not an instance method. |
| IMA_Error_Unrelated | All possible referrents are instance members of an unrelated class. |

◆ BuildMSPropertyRefExpr()

VK should be set in advance to the value kind of the base expression.

◆ ClassifyImplicitMemberAccess()
The given lookup names class member(s) and is not being used for an address-of-member expression.
Classify the type of access according to whether it's possible that this reference names an instance member. This is best-effort in dependent contexts; it is okay to conservatively answer "yes", in which case some errors will simply not be caught until template-instantiation.

◆ LookupMemberExpr()
Look up the given member of the given non-type-dependent expression.
This can return in one of two ways:
- If it returns a sentinel null-but-valid result, the caller will assume that lookup was performed and the results written into the provided structure. It will take over from there.
- Otherwise, the returned expression will be produced in place of an ordinary member expression.
The ObjCImpDecl bit is a gross hack that will need to be properly fixed for ObjC++.

Given that normal member access failed on the given expression, and given that the expression's type involves builtin-id or builtin-Class, decide whether substituting in the redefinition types would be profitable.
The redefinition type is whatever this translation unit tried to typedef to id/Class; we store it to the side and then re-use it in places like this.
