AllowOverloadingOfFunction()

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

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.

getImplicitCodeSegAttrFromClass()

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

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.

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.

Returns

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.
