They use -mrtm (like we use -mhtm) to build libitm, but it looks like their -mrtm does not enable any other isa flags like we currently are doing with -mhtm. Meaning their -mrtm option is independent of any -mcpu values while ours is not. If we revert the patch I mentioned, then I think we will match what Intel is doing. Hopefully Jakub will correct me if I am wrong. Peter
