From 6a7524c6aa18f5afa4977314eb01f0360e752789 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Thu, 8 Mar 2018 14:34:09 +1030 Subject: [PATCH] Really remove unnecessary power9 group terminating nop Oops, not tested well enough. -mpower9 sets all the PPC_OPCODE_POWERn for n <= 9. * config/tc-ppc.c (ppc_handle_align): Correct last patch. Really don't emit a group terminating nop for power9.
