From 1db9e0513d7478f6c80ca0bc4f58f53fe49e27f8 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Wed, 30 Oct 2013 12:12:50 +0100 Subject: s390: allow to set gcc -mtune flag Add a new Kconfig choice group which allows to configure how gcc should tune the generated code (via -mtune option). By default the -mtune parameter will match the -march parameter. This is a rather large patch, but I wouldn't know how to make this shorter unfortunately.
