On my machine, Athlon XP 2500 running Fedora Core 3,
-O2 -march=i686 produces OK!, but
-O2 -march=athlon-xp produces WRONG!
if the original testcase is compiled with the current mainline.

As per GDR (a while back) moving 3.4.x regressions to the target milestone for

"-O -frerun-cse-after-loop" is enough to reproduce it on AMD64.

Oh bugger. The tree dump is good.

The tree dump already looks wrong to me on mainline:
g (k, l)
{
int j.0;
int j;
_Bool D.1460;
int D.1459;
int D.1458;
int D.1457;
:
D.1457 = f ();
if (D.1457 != 0) goto ; else g

I can confirm this bug on mainline with this testcase:
--
void abort (void);
int f ()
{
return 0;
}
void __attribute
