-;
-; Instruction does not dominate all uses!
-; %t2 = load i16, i16* @b, align 1, !tbaa !2, !alias.scope !6
-; %tobool = icmp eq i16 %t2, 0
-; LLVM ERROR: Broken function found, compilation aborted!
-;
-; due to a fault where we did not replace the use of %t2 in the icmp in
-; for.end, when adding a new PHI node for the versioned loops based on the
-; loop-defined values used outside of the loop.
-;
-; Verify that the code compiles, that we get a versioned loop, and that the
-; uses of %t2 in for.end and if.then are updated to use the value from the
-; added phi node.
