From 4bbc8970688295e9883f152ea84fb7d8cbd6e877 Mon Sep 17 00:00:00 2001 From: Robin Dapp Date: Mon, 6 Mar 2017 12:40:19 +0000 Subject: [PATCH] S/390: Change 2-byte NOPs 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. gcc/ChangeLog: 2017-03-06 Robin Dapp * config/s390/s390.c (s390_asm_output_function_label): Use nopr %r0. * config/s390/s390.md: Likewise. gcc/testsuite/ChangeLog: 2017-03-06 Robin Dapp * gcc.target/s390/hotpatch-1.c: Check for nopr %r0. * gcc.target/s390/hotpatch-10.c: Likewise. * gcc.target/s390/hotpatch-11.c: Likewise. * gcc.target/s390/hotpatch-12.c: Likewise. * gcc.target/s390/hotpatch-13.c: Likewise. * gcc.target/s390/hotpatch-14.c: Likewise. * gcc.target/s390/hotpatch-15.c: Likewise. * gcc.target/s390/hotpatch-16.c: Likewise. * gcc.target/s390/hotpatch-17.c: Likewise. * gcc.target/s390/hotpatch-18.c: Likewise. * gcc.target/s390/hotpatch-19.c: Likewise. * gcc.target/s390/hotpatch-2.c: Likewise. * gcc.target/s390/hotpatch-26.c: Likewise. * gcc.target/s390/hotpatch-27.c: Likewise. * gcc.target/s390/hotpatch-28.c: Likewise. * gcc.target/s390/hotpatch-3.c: Likewise. * gcc.target/s390/hotpatch-4.c: Likewise. * gcc.target/s390/hotpatch-5.c: Likewise. * gcc.target/s390/hotpatch-6.c: Likewise. * gcc.target/s390/hotpatch-7.c: Likewise. * gcc.target/s390/hotpatch-8.c: Likewise. * gcc.target/s390/hotpatch-9.c: Likewise.
