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.
