--- Comment #3 from Patrick Palka <ppalka at gcc dot gnu.org> ---
What seems to be happening is determine_visibility correctly notices that
begin<R> should have internal linkage due to R having internal linkage, so it
proceeds to clear TREE_PUBLIC, DECL_COMDAT, DECL_EXTERN, etc for begin<R>.
Later in cgraph_node::finalize for begin<R>, we force its definition to be
outputted due to
/* When not optimizing, also output the static functions. (see
PR24561), but don't do so for always_inline functions, functions
declared inline and nested functions. These were optimized out
in the original implementation and it is unclear whether we want
to change the behavior here. */
if (((!opt_for_fn (decl, optimize) || flag_keep_static_functions
|| node->no_reorder)
&& !node->cpp_implicit_alias
&& !DECL_DISREGARD_INLINE_LIMITS (decl)
&& !DECL_DECLARED_INLINE_P (decl)
&& !(DECL_CONTEXT (decl)
&& TREE_CODE (DECL_CONTEXT (decl)) == FUNCTION_DECL))
&& !DECL_COMDAT (decl) && !DECL_EXTERNAL (decl))
node->force_output = 1;
I guess we need to somehow refine the above test to exclude implicit
instantiations with internal linkage?
