◆ DeclHasAttr() ◆ diagnoseImplicitlyRetainedSelf() static void diagnoseImplicitlyRetainedSelf ( Sema &  S ) static ◆ DiagnoseInvalidRedeclaration()

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.

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;

};

This routine is recursive, injecting the names of nested anonymous structs/unions into the owning context and scope as well.
