Bug ID: 63532
Summary: Cannot increase access of member function template.
Product: gcc
Version: 4.9.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: bugs at qult dot net
The following code is rejected by GCC while it is accepted by Clang.
struct Foo {
template <typename>
void meth();
};
struct Bar : private Foo {
using Foo::meth;
};
int main()
{
(void) &Bar::meth<int>;
}
GCC accepts a variant where Foo::meth is a plain (i.e., non-template) member
function.

--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
G++ accepts the using declaration but it seems to have no effect when forming a
pointer to member for a specialization:
in.cc: In function âint main()â:
in.cc:3:11: error: âvoid Foo::meth() [with <template-parameter-1-1> = int]â is
inaccessible
void meth();
^
in.cc:12:16: error: within this context
(void) &Bar::meth<int>;
^

Short repro
The attached reprocase contains an innocent function which can not ever benefit
from inlining. But fnsplit pass still jumps on it and splits it to two
functions thus hurting performance and code size:
gcc -O2 -fconserve-stack -S repro.i -o-
...g.part.0:
...
g:
...
call g.part.0
This can not be recovered later by inliner because of -fconserve-stack option.
The reprocase is a reduced version of a real-world code (from Linux kernel).

This is similar issue to PR 56152 (static call vs non-static).
