[PATCH] S/390: Change 2-byte NOPs

2017-03-01 Thread Robin Dapp
Hi, the following patch changes "nopr %r7" to "nopr %r0" which is advantageous from a hardware perspective. It will only be emitted for hotpatching and should not impact normal code. Bootstrapped and regression tested on s390 and s390x. Regards Robin gcc/ChangeLog: 2017-03-02 Robin Dapp
