Hmm, I cannot reproduce this on a cross from powerpc-darwin (but it might be a local patch which is 
causing it to pass which I doubt it).

[Bug target/18321] [3.2 regression] mmix-knuth-mmixware testsuite failure: gcc.c-torture/compile/20031023-4.c -O0, -O1

[hp at gcc dot gnu dot org]

------- Additional Comments From hp at gcc dot gnu dot org  2004-12-28 17:47 -------
A bug in the epilogue code: using "int" instead of HOST_WIDE_INT.
This is a regression from 3.2, where the code got a clear error
(the test-case wasn't present there, though):
/gcc/testsuite/gcc.c-torture/compile/20031023-1.c: In function `bar':
/gcc/testsuite/gcc.c-torture/compile/20031023-1.c:38: stack frame too big
A fix seems trivial.

This isn't a 4.0 regression, it's a 3.2 regression. If you change it again,
please add a comment.

if you mean it is a regression from 3.2, then to mark it as such, not the other way around which is what 
you marked it as.

In reply to Comment #6, I did in comment #4.
I also changed the PR title, because [3.2 regression] meant to me a regression
from 3.2.  I see <URL:http://gcc.gnu.org/bugs/management.html> says otherwise.
Oh well.  Though as I'm not going to change 3.3 or 3.4 (too odd case, but do
feel free after a build and check), I changed back the title to say 4.0.

...oh right: "needs fixing" isn't the same as "going to be fixed".  Changed
back to 3.3/3.4/4.0.  Gah.

Hans, this was also a regression in 3.3 and 3.4, the patch should be applied 
there, or you should clarify that you are not going to fix the branches.

In response to comment #11:
You should clarify what clarification you expect besides what I say in comment
#7 and the target milestone setting.  Perhaps you missed it, because it was said
in passing?  In <URL:http://gcc.gnu.org/bugs/management.html> i see nothing
further on this.  Please add whatever clarification there too.
Again: I'm not going to apply the patch myself on those branches,
but I preapprove backporting it there, assuming the required before/after test
is done, of course.

Hans: our policy prescribes that a regression in Bugzilla be kept open until it 
is fixed on all the active release branches, *or* the maintainter of the code 
affected by the bug explicitally decides that this bug will not be fixed in the 
branches.

This said, I had missed your note in comment #7. Since you are the maintainer 
of mmix, it is up to you to decide if you want to keep this bug in the branches 
or fix it there as well. If you prefer to not fix it, then it's fine.

If HP believs that he has no interest in having the bug fixed on the
branches for mmix-knuth-xx users, let's close the PR.

I have interest, but only a little, not even as much as doing the minimal
work myself.  The PR is already closed.  Nothing here to see, move on.
