From ee723ffabb4c76f4c1924436af145f5eca1012fc Mon Sep 17 00:00:00 2001 From: Anuj Phogat Date: Thu, 27 Jun 2013 16:12:07 -0700 Subject: mesa: Return ZeroVec/dummyReg instead of NULL pointer Assertions are not sufficient to check for null pointers as they don't show up in release builds. So, return ZeroVec/dummyReg instead of NULL pointer in get_{src,dst}_register_pointer(). This should calm down the warnings from static analysis tool. Note: This is a candidate for the 9.1 branch.
