◆ AllowOverloadingOfFunction()

static bool AllowOverloadingOfFunction ( const LookupResult Previous,

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 alway permitted) or, as a C extension, when either the new declaration or a previous one is declared with the 'overloadable' attribute.

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.

[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.
