Richard Smith 541b38be7b Switch the semantic DeclContext for a block-scope declaration of a function or ... variable from being the function to being the enclosing namespace scope (in C++) or the TU (in C). This allows us to fix a selection of related issues where we would build incorrect redeclaration chains for such declarations, and fail to notice type mismatches. Such declarations are put into a new IdentifierNamespace, IDNS_LocalExtern, which is only found when searching scopes, and not found when searching DeclContexts. Such a declaration is only made visible in its DeclContext if there are no non-LocalExtern declarations. llvm-svn: 191064		2013-09-20 01:15:31 +00:00
