Changes in directory llvm/lib/CodeGen/SelectionDAG:
SelectionDAG.cpp updated: 1.305 -> 1.306
---
Log message:
Compile:
%tmp152 = setgt uint %tmp144, %tmp149 ; <bool> [#uses=1]
%tmp159 = setlt uint %tmp144, %tmp149 ; <bool> [#uses=1]
%bothcond2 = or bool %tmp152, %tmp159 ; <bool> [#uses=1]
To setne, not setune, which causes an assertion fault.
