From 4408d0ccd8b860cdbcc63f7f4dd835cab37c6581 Mon Sep 17 00:00:00 2001 From: Thiago Macieira Date: Mon, 27 Feb 2012 15:32:47 +0100 Subject: Rename qatomic_x86_64.h to qatomic_x86.h This is the first step in merging the i386 and x86-64 architectures. The next commit will bring i386 support into qatomic_x86.h. Change-Id: I24105ea70f3fc29b3fb779a70053f99117440573 Reviewed-by: Bradley T.
