Author: slthakur Date: Tue Aug 25 04:52:59 2015 New Revision: 245927 URL: http://llvm.org/viewvc/llvm-project?rev=245927&view=rev Log: 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.
