c++: Fix bogus warning in deprecated namespace [PR99318]
In GCC 10, I introduced cp_warn_deprecated_use_scopes so that we can
handle attribute deprecated on a namespace declaration. This
function walks the decl's contexts so that we warn for code like
namespace [[deprecated]] N { struct S { }; }
N::S s;
We call cp_warn_deprecated_use_scopes when we encounter a TYPE_DECL.
But in the following testcase we have a TYPE_DECL whose context is
a deprecated function; that itself is not a reason to warn. This
patch limits for which entities we call cp_warn_deprecated_use;
essentially it's what can follow ::.
I noticed that we didn't test that
struct [[deprecated]] S { static void fn(); };
S::fn();
produces the expected warning, so I've added gen-attrs-73.C.
gcc/cp/ChangeLog:
PR c++/99318
* decl2.c (cp_warn_deprecated_use_scopes): Only call
cp_warn_deprecated_use when decl is a namespace, class, or enum.
