The same change gcc.c-torture/execute/20040709-2.c on all hppa targets
(both 32 and 64 bit). On hppa64-hp-hpux11.11, testK is the first test
to fail. In this case, it appears retmeK is miscompiled.

This:
templatetypename F class Foo { friend class F; };
gets you this:
~/ootbc/asm$ g++ foo.cc
foo.cc:2: error: using template type parameter F after class

Because the C++ standard says you cannot. See PR 24629.

Not really a regression as the warning was just enabled in the first place
recently.

I think the problem is that the vector cost model is not tune for the Intel
Core family.
My understanding of the problem is that without the relevant suboption of
-ffast-math
the inner implicit loops in induct are

I noticed this while looking into tree-ssa-sccvn.c sources (though I doubt it
helps in general really). But anyways we should optimize the following code
into just a return 0;:
struct f
{
int t, k;
int g[1024];
};
int g(void)
{
struct f a;
__builtin_memset(a, 0, sizeof(a));

Yes, but this requires quite a complicated workaround (solution (4) in my
comment #109).
The problem is on the compiler side, which could store every result of a cast
or an assignment to

Is there any possibility for gfortran's output

IMHO when a new optimization technique is enabled by default in -O3
and degrades common benchmark performance, it qualifies as a
performance regression for that release.
