From dd99a3cc5dd7f369d6463245a88a413262bf5948 Mon Sep 17 00:00:00 2001 From: Sasha Levin Date: Thu, 30 Aug 2012 09:36:41 +0200 Subject: [PATCH] kvm tools: enable LTO Build with -flto set, which should enable link-time-optimizations. I'm not sure if it provides a significant performance increase, but it's probably just worth it for catching issues which it may cause.
