From 68a971acc9484559ae8e1cc80950f34919299eba Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Sun, 1 May 2022 21:05:59 +0200 Subject: [PATCH] s390/extable: prefer local labels in .set directives Use local labels in .set directives to avoid potential compile errors with LTO + clang. See commit 334865b2915c ("x86/extable: Prefer local labels in .set directives") for further details. Since s390 doesn't support LTO currently this doesn't fix a real bug for now, but helps to avoid problems as soon as required pieces have been added to llvm.
