Hi, I have submitted the patch to fix the ABI mis-matching error caused by LTO on 18th June 2014.
Refer to : https:// gcc.gnu.org/ml/gcc-patches/2014-06/msg01429.html for details. This fix was done for trunk. We need this fix included for gcc 4.9 branch. So could we back porting this fix to upstream gcc 4.9 branch? Thanks and Best Regards, Hale Wang
