------- Comment #14 from hjl dot tools at gmail dot com 2008-08-29 18:24 -------
I suspect this patch
http://gcc.gnu.org/ml/gcc-patches/2008-08/msg01903.html
is incorrect. Back it out from IRA branch fixed the testcase
in comment #11. I am running SPEC CPU 2000/2006 with IRA
branch using revision 139581 and revision 139582 on Linux/ia32
and Linux/Intel64. It will tell us if revision 139582 is bad.
