Generate diagnostics for an invalid function redeclaration.

This routine handles generating the diagnostic messages for an invalid function redeclaration, including finding possible similar declarations or performing typo correction if there are no previous declarations with the same name.

Returns a NamedDecl iff typo correction was performed and substituting in the new declaration name does not cause new errors.

◆ getImplicitCodeSegAttrFromClass()

static Attr* getImplicitCodeSegAttrFromClass ( Sema S,

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 – this includes compiler-generated special member functions – 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.

hasSimilarParameters - Determine whether the C++ functions Declaration and Definition have "nearly" matching parameters.

This heuristic is used to improve diagnostics in the case where an out-of-line function definition doesn't match any declaration within the class or namespace. Also sets Params to the list of indices to the parameters that differ between the declaration and the definition. If hasSimilarParameters returns true and Params is empty, then all of the parameters match.

InjectAnonymousStructOrUnionMembers - Inject the members of the anonymous struct or union AnonRecord into the owning context Owner and scope S.

This routine will be invoked just after we realize that an unnamed union or struct is actually an anonymous union or struct, e.g.,

union {
int i;
float f;
}; // InjectAnonymousStructOrUnionMembers called here to inject i and
// f into the surrounding scope.x

◆ isIncompleteDeclExternC()

template<typename T >
static bool isIncompleteDeclExternC ( Sema S,
const T *  D 
)
static

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.

FIXME: This is a hack.

◆ isOutOfScopePreviousDeclaration()

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

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
PrevDeclthe previous declaration found by name lookup
DCthe 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.
