Gcc 4.0.3 20051207 miscompiles fma3d in SPEC CPU 2K when -O2 on i686 and
x86-64.
I got
Running Benchmarks
Running 191.fma3d ref base o2 default
Child returned with invalid return code(0)
*** Miscompare of fma3d.out, see
/export/spec/src/2000/spec/benchspec/CFP2000/191.fma3d/run/00000002/fma3d.out.mis
Gcc 4.1 and 4.2 are OK.

It looks like a regression. Gcc 4.0.2 20050912 works fine.

Gcc 4.0.3 20051113 is bad. So this regression was introduced between 20051111
and 20051113.

I have verified that
http://gcc.gnu.org/ml/gcc-patches/2005-11/msg00874.html
is the cause. Since gcc 4.1 and 4.2 are OK, the problem may be in the backport.

OK, I see now this is not a problem in 4.1 or 4.2. Yes, backport problem.

My apologies, I was looking at the wrong place.
Grigory, thanks for test case.
I have regression tested the patch and see no new failures. There are some
NIST failures, but these are not affected by the patch. We have already fixed
those failures in 4.1 and 4.2.
I will commit the patch tonight as "obvious"
Again, sorry for the confusion.

Evidently I do not have authorization to commit to the 4.0 branch. (I tried
twice) Here is a completed and ready testcase. I strongly suggest people move
on to 4.1 if at all possible. If someone else wants to commit this, please do.

Shouldn't that case also be added to 4.1 and mainline to prevent this bug
from happening there?

------- Comment #22 from kargl at gcc dot gnu dot org 2005-12-20 17:01 -------
The testcase isn't needed and should not be committed.
As explained elsewhere, the problem was caused by merging
one line from a 4.1 patch into 4.0 that should not have
been committed. Jerry has fixed that problem. With very
limited gfortran manpower, gfortran 4.0.x will see very few
if any new changes.
In fact, using gfortran 4.0.x to obtain SPEC benchmarks is
actually rather stupid. Do yourself a favor and upgrade to
gfortran 4.1 (pre-release).
