[lihan via Phabricator via llvm-commits]

lihan2011 added a comment.

when i use SMS.enterRegion(MBB, MBB->begin(), MBB->getFirstTerminator(), size); it occurs 
Assertion failed: VNI && "No value to read by operand"
but if use SMS.enterRegion(MBB, MBB->getFirstNonPHI(), MBB->getFirstTerminator(), size2); it has no error.
Am i use the wrong version of LLVM?
