The last time I checked it wasn't, mainly because this is not really
an IPA problem (if it was, indirect inlining would handle it just
fine).
I believe the current plan is to make early FRE fix this, see the
discussion in PR 40874.

For the record, my favorite example in the C++ library,
testsuite/performance/27_io/fmtflags_manipulators.cc, pretty simple, still
probably noticeable by many of our users, is by now perfectly optimized at -O2.
Many thanks.

--- Comment #31 from Jan Hubicka <hubicka at gcc dot gnu.org> 2013-01-16 14:20:46 UTC ---
Well, after early optimizations we get:
int main() ()
{
struct Foo x;
void Foo::<T392> (const struct Foo *) * iftmp.0;
long int _3;
long int _4;
int (*__vtbl_ptr_type) () * _5;
long int _6;
sizetype _7;
int (*__vtbl_ptr_type) () * _8;
<bb 2>:
_3 = (long int) Bar;
_4 = _3 & 1;
if (_4 == 0)
goto <bb 4>;
else
goto <bb 3>;
<bb 3>:
_5 = MEM[(int (*__vtbl_ptr_type) () * *)&x];
that is only later, at ccp2 times turned int
int main() ()
{
struct Foo x;
long int _3;
<bb 2>:
_3 = (long int) Bar;
Foo::Bar (&x);
x ={v} {CLOBBER};
return 0;
}
ccp1 s not able to do this because it still sees:
int main() ()
{
struct
{
void Foo::<T392> (const struct Foo *) * __pfn;
long int __delta;
} y;
struct Foo x;
void Foo::<T392> (const struct Foo *) * iftmp.0;
void Foo::<T392> (const struct Foo *) * _5;
long int _6;
long int _7;
long int _9;
sizetype _10;
struct Foo * _11;
int (*__vtbl_ptr_type) () * _12;
void Foo::<T392> (const struct Foo *) * _13;
long int _14;
long int _15;
sizetype _16;
int (*__vtbl_ptr_type) () * _17;
long int _19;
sizetype _20;
const struct Foo * _21;
<bb 2>:
y.__pfn = Bar;
y.__delta = 0;
_5 = y.__pfn;
_6 = (long int) _5;
_7 = _6 & 1;
if (_7 == 0)
goto <bb 3>;
else
goto <bb 4>;
This is fixed by SRA to:
<bb 2>:
y$__pfn_4 = Bar;
y$__delta_3 = 0;
_5 = y$__pfn_4;
_6 = (long int) _5;
_7 = _6 & 1;
if (_7 == 0)
goto <bb 3>;
else
goto <bb 4>;
<bb 3>:
iftmp.0_8 = y$__pfn_4;
Richi, is there chance for subsequent FRE to catch this?

Actually the testcase above is not really valid.
The below testcase is more correct as A::p cannot be inlined as it has its address taken (stupid bug in
the C++ front-end really).
But here is a better testcase:
struct A
{
void foo()
{
}
};
int main()
{
void (A::* const p)() = & A::foo;
A a;
(a.*p)();
}
---- cut ---
D.1749 = (int) foo;
if ((D.1749 & 1) != 0) goto <L0>; else goto <L5>;
hmm, we need to know the alignment of a function, which is weird. Why is the C++ front-end
producing code like this, oh well.

... alternately, one we really care about, performance-wise, could be distilled
from libstdc++-v3/testsuite/performance/27_io/fmtflags_manipulators.cc...
