Dodji Seketeli d10402b413 PR c++/54372 - unused attribute inactive on dependant entities ... In the example of this patch, gcc/g++ invoked with -Wunused-local-typedefs warns on dependant entities even when those are decorated with the 'unused' attribute. This is because in cplus_decl_attributes, save_template_attributes makes so that the 'unused' attribute is applied to its appertaining entity only at instantiation time. But then at parsing time maybe_warn_unused_local_typedefs checks for TREE_USED before warning. This patch applies the 'unused' attribute at compilation time. Tested on x86_64-unknown-linux-gnu against trunk. gcc/cp/ * decl2.c (is_late_template_attribute): "unused" attribute is to be applied at compile time. gcc/testsuite/ * c-c++-common/Wunused-local-typedefs-2.c: New test.
