From a9f5cee7edaa88eaf77d134dc1b370ad7d91ed9f Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Wed, 11 Sep 2013 09:29:33 +0200 Subject: [PATCH] s390: always set -march compiler option Currently we only set the -march compiler option if the kbuild system figured out that the compiler actually supports the selected architecture (cc-option test). In result this means that no -march compiler option is set when an unsupported cpu architecture of the current compiler is selected. The kernel compile will afterwards succeed but with the default architecture instead of the (unsupported) selected one. Change this behaviour, so compiles will fail if the compiler does not support the selected cpu architecture.
