From 0efa470363699ecba49e67cc3c75f46b300f98a4 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Thu, 28 Sep 2006 16:55:46 +0200 Subject: [S390] config option for z9-109 code generation. Add a kernel config option for the IBM System z9. This will produce faster code on newer compilers using the -march=z9-109 option.
