c++: vtable referring to "unavailable" virtual fn [PR116606]
mark_vtable_entries already has
/* It's OK for the vtable to refer to deprecated virtual functions. */
warning_sentinel w(warn_deprecated_decl);
but that doesn't cover __attribute__((unavailable)). We can use the
following override to cover both.
PR c++/116606
gcc/cp/ChangeLog:
* decl2.cc (mark_vtable_entries): Temporarily override deprecated_state to
UNAVAILABLE_DEPRECATED_SUPPRESS. Remove a warning_sentinel.
gcc/testsuite/ChangeLog:
* g++.dg/ext/attr-unavailable-13.C: New test.
