------- Comment #4 from dominiq at lps dot ens dot fr 2010-09-10 12:59 -------
The test in comment #0 has been fixed by revision 164111. However it seems that
191.fma3d in
SPEC CPU 2K is not fixed by this revision (see
http://gcc.gnu.org/ml/gcc-testresults/2010-09/msg00913.html ).

------- Comment #5 from dominiq at lps dot ens dot fr 2010-09-10 13:24 -------
Since pr45634 has been opened for the failure of 191.fma3d in SPEC CPU 2K, I am
closing this one as fixed. Thanks for the commit.
