From 5ea2bad0d9ab6a2465195badd323313553baa61b Mon Sep 17 00:00:00 2001 From: Michael Kinney Date: Wed, 9 Nov 2016 18:31:38 -0800 Subject: MdePkg/BaseMemoryLib: Fix VS2015 build error https://bugzilla.tianocore.org/show_bug.cgi?id=237 Make the smallest change possible to workaround a VS2015 build error. The change is to the loop that handles the case where neither the source nor the destination are 64-bit or 32-bit aligned and the logic falls through to a loop that performs the copy as bytes. Only the loop that copies bytes backwards needs to be updated to avoid the VS2015 build error.
