your 89 arm failures compared to the mainline are the reason that I
still want to hold off.
Seongbae found a bug in the post decrement code today that I sent him a
private patch for and he is moving to the next ia-64 bug even as we speak.
I expect that he will post a progress report patch sometime soon with
the several ia-64 fixes he has made and then we can retest the arm.
However, I admit that these results are promising. I just think that we
should wait until we can test this clean.
