nickdesaulniers added a comment. > in SelectionDAGBuilder::visitCallBr
So the issue I hit immediate is that the ValueMap SelectionDAG has maps the indirect destination BB to the original MBB; I can't split the edge and have the CallBrInst lower correctly to refer to the synthesized MBB. I think I can reuse this commit mostly as is, just move it from codegen prepare to another pass. It looks like `indirectbr-expand` _is_ enabled at `-O0` and is necessary for correctness IIUC. Thoughts on moving this there, and maybe renaming the pass to `indirectbr-callbr-expand`?
