I've been reading through the ABCD implementation in jitrino, and if
I understand it correctly, I found a bug. I've attached a patch to
fix it. Someone who actually understands the code should verify this.
Also, did anyone ever test this ABCD pass? I ask because I've tried
running it on a bidirectional bubble sort as mentioned in the
original paper. The paper mentions that the pass should be able to
prove all of the bounds checks in the sort method as redundant/
unnecessary. However, when I try running the abcd pass on a
bidirectional bubble sort (attached), none of the bounds checks are
eliminated.
