From 6a11f92ef449bfb87f93e7cc14cb2a717afc7aa3 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Wed, 16 May 2012 08:59:04 +0200 Subject: perf tools: Add union u64_swap type for swapping u64 data The following union: union { u64 val64; u32 val32[2]; } u; is used on more than one place in perf code and will be used more in upcomming patches. Adding union u64_swap to have it defined globaly so we dont need to redefine it all the time.
