--- Comment #3 from Segher Boessenkool <segher at gcc dot gnu.org> --- So, compgotos does its job just fine. It has duplicated the indirect jump to all its predecessors. One of those is a block that just does an add (the op++ from the testcase) and then jumps to the indirect jump. I'd expect bb-reorder to copy the resulting block -- it's just a few insns -- but it doesn't. Investigating.
