From 8152e00dce1972be8ad3a39804d65cf8a67a3211 Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Tue, 20 Jun 2017 16:23:13 +0100 Subject: [PATCH] examples/performance-thread: remove non-SSE4 fallbacks Since this example is for x86_64 platforms only, and since SSE4 is now a mandatory requirement, we can remove the ifdefs checking for that instruction set level, and the fallbacks if it is not present.
