Do you have commit access? It would be good to push the original tests as a preliminary patch.



================
Comment at: llvm/test/Transforms/InstCombine/abs-intrinsic.ll:473
+  %0 = call i32 @llvm.abs.i32(i32 %sub, i1 true)
+  %add = add nsw i32 %0, %x
+  br label %cond.end
----------------
Why did the 'add' operand change from %y to %x?
