AllowOverloadingOfFunction()

static bool AllowOverloadingOfFunction ( const LookupResult &  Previous, ASTContext &  Context, const FunctionDecl *  New  )

static

Determine whether overloading is allowed for a new function declaration considering prior declarations of the same name.

This routine determines whether overloading is possible, not whether a new declaration actually overloads a previous one. It will return true in C++ (where overloads are always permitted) or, as a C extension, when either the new declaration or a previous one is declared with the 'overloadable' attribute.

static bool checkForConflictWithNonVisibleExternC ( Sema &  S, const T *  ND, LookupResult &  Previous  )

Apply special rules for handling extern "C" declarations.

Returns true if we have found that this is a redeclaration of some prior entity.

Per C++ [dcl.link]p6: Two declarations [for a function or variable] with C language linkage with the same name that appear in different scopes refer to the same [entity]. An entity with C language linkage shall not be declared with the same name as an entity in global scope.

getImplicitCodeSegAttrFromClass()

static Attr * getImplicitCodeSegAttrFromClass ( Sema &  S, const FunctionDecl *  FD  )

static

Return a CodeSegAttr from a containing class.

The Microsoft docs say when __declspec(code_seg) "is applied to a class, all member functions of the class and nested classes &ndash; this includes compiler-generated special member functions &ndash; are put in the specified segment." The actual behavior is a little more complicated. The Microsoft compiler won't check outer classes if there is an active value from #pragma code_seg. The CodeSeg is always applied from the direct parent but only from outer classes when the #pragma code_seg stack is empty. See: https://reviews.llvm.org/D22931, the Microsoft feedback page is no longer available since MS has removed the page.

Determine whether a variable is extern "C" prior to attaching an initializer.

We can't just call isExternC() here, because that will also compute and cache whether the declaration is externally visible, which might change when we attach the initializer.

This can only be used if the declaration is known to not be a redeclaration of an internal linkage declaration.

For instance:

auto x = []{};

Attaching the initializer here makes this declaration not externally visible, because its type has internal linkage.

isOutOfScopePreviousDeclaration()

static bool isOutOfScopePreviousDeclaration ( NamedDecl *  PrevDecl, DeclContext *  DC, ASTContext &  Context  )

Determines whether the given declaration is an out-of-scope previous declaration.

This routine should be invoked when name lookup has found a previous declaration (PrevDecl) that is not in the scope where a new declaration by the same name is being introduced. If the new declaration occurs in a local scope, previous declarations with linkage may still be considered previous declarations (C99 6.2.2p4-5, C++ [basic.link]p6).

Parameters

PrevDecl	the previous declaration found by name lookup
DC	the context in which the new declaration is being declared.

true if PrevDecl is an out-of-scope previous declaration for a new delcaration with the same name.

[class.mem.special]p6: An eligible special member function is a special member function for which:

• the function is not deleted,
• the associated constraints, if any, are satisfied, and
• no special member function of the same kind whose associated constraints [CWG2595], if any, are satisfied is more constrained.
