From 30241177574be6cd03677884a9ece5c5bf823653 Mon Sep 17 00:00:00 2001 From: Sagar Thakur Date: Tue, 25 Aug 2015 09:52:59 +0000 Subject: Fix build on mips Setting and getting register values as bytes instead of depending on the 128 bit integer support in register value. This patch will fix the build failure in the release branch.
