[PATCH] D127115: [DAGCombine] Make sure combined nodes are added back to the worklist in topological order.

[Amaury SECHET via Phabricator via llvm-commits]

deadalnix added a comment.

I have this one, which repro and is simpler:

  define i64 @foo(i1 %0) {
    br label %2
  
  2:
    %3 = select i1 %0, i1 %0, i1 false
    %4 = freeze i1 %3
    br i1 %4, label %5, label %6
  
  5:
    br label %6
  
  6:
    %7 = phi i64 [ 0, %5 ], [ 1, %2 ]
    ret i64 %7
  }

I'll figure out a fix. That doesn't sound complicated.
